Adding mobile ions to an OLED creates a light-emitting electrochemical cell (LEC) which has a slightly different mode of operation. An OLED display can be driven with a passive-matrix (PMOLED) or active-matrix (AMOLED) control scheme. In the PMOLED scheme, each row (and line) in the display is controlled sequentially, one by one,[6] whereas AMOLED control uses a thin-film transistor backplane to directly access and switch each individual pixel on or off, allowing for higher resolution and larger display sizes.

Colour patterning can be accomplished by means of a laser, such as a radiation-induced sublimation transfer (RIST).[83] Researchers report luminescence from a single polymer molecule, representing the smallest possible organic light-emitting diode (OLED) device.[54] Scientists will be able to optimize substances to produce more powerful light emissions. Finally, this work is a first step towards making molecule-sized components that combine electronic and optical properties. Similar components could form the basis of a molecular computer.[55]

Phosphorescent organic light-emitting diodes use the principle of electrophosphorescence to convert electrical energy in an OLED into light in a highly efficient manner,[65][66] with the internal quantum efficiencies of such devices approaching 100%.[67] Oled Tv Fiyatları en ucuz fiyat seçenekleriyle Cimri.com'da!

Patternable organic light-emitting devices use a light or heat activated electroactive layer. A latent material (PEDOT-TMA) is included in this layer that, upon activation, becomes highly efficient as a hole injection layer. Using this process, light-emitting devices with arbitrary patterns can be prepared.[82] Applications of OLEDs in solid state lighting require the achievement of high brightness with good CIE coordinates (for white emission). The use of macromolecular species like polyhedral oligomeric silsesquioxanes (POSS) in conjunction with the use of phosphorescent species such as Ir for printed OLEDs have exhibited brightnesses as high as 10,000 cd/m2.[68]

OLED-Info is the web's leading OLED publication. We work nonstop to bring you news, resources OLED devices use organic semiconductors to create beautiful, flexible and efficient display panels Almost all OLED manufacturers rely on material deposition equipment that is only made by a handful of companies,[126] the most notable one being Canon Tokki, a unit of Canon Inc. Canon Tokki is reported to have a near-monopoly of the giant OLED-manufacturing vacuum machines, notable for their 100-metre (330 ft) size.[127] Apple has relied solely on Canon Tokki in its bid to introduce its own OLED displays for the iPhones released in 2017.[128] The electroluminescent materials needed for OLEDs are also made by a handful of companies, some of them being Merck, Universal Display Corporation and LG Chem.[129] The machines that apply these materials can operate continuously for 5–6 days, and can process a mother substrate in 5 minutes.[130] Ultra-thin profile and light weight, energy efficient, superb picture quality and accurate color JOLED started operation of the world's first mass production line of printed OLED displays constructed in its..

  1. As electrons and holes are fermions with half integer spin, an exciton may either be in a singlet state or a triplet state depending on how the spins of the electron and hole have been combined. Statistically three triplet excitons will be formed for each singlet exciton. Decay from triplet states (phosphorescence) is spin forbidden, increasing the timescale of the transition and limiting the internal efficiency of fluorescent devices. Phosphorescent organic light-emitting diodes make use of spin–orbit interactions to facilitate intersystem crossing between singlet and triplet states, thus obtaining emission from both singlet and triplet states and improving the internal efficiency.

For example, the 2010 Lexus RX features an OLED display instead of a thin film transistor (TFT-LCD) display. OLED displays were used in watches made by Fossil (JR-9465) and Diesel (DZ-7086). Other manufacturers of OLED panels include Anwell Technologies Limited (Hong Kong),[138] AU Optronics (Taiwan),[139] Chimei Innolux Corporation (Taiwan),[140] LG (Korea),[141] and others.[142] In 2009, Shearwater Research introduced the Predator as the first color OLED diving computer available with a user replaceable battery.[143][144] BlackBerry Limited, the maker of BlackBerry smartphones, uses OLED displays in their BlackBerry 10 devices.

In the same month, Samsung unveiled what was then the world's largest OLED Television at 40-inch with a Full HD resolution of 1920 × 1080 pixels.[168] In the FPD International, Samsung stated that its 40-inch OLED Panel is the largest size currently[when?] possible. The panel has a contrast ratio of 1,000,000:1, a colour gamut of 107% NTSC, and a luminance of 200 cd/m2 (peak luminance of 600 cd/m2). 有机发光二极管(Organic Light Emitting Diodes,OLED)依驱动方式的不同又可分为被动式(Passive Matrix,PMOLED)与主动式(Active Matrix,AMOLED),目前以三星为代表的显示屏厂商主要运用AMOLED 。The search for efficient OLED materials has been extensively supported by simulation methods; it is possible to calculate important properties computationally, independent of experimental input,[212][213] making materials development cheaper. The Sony CLIÉ PEG-VZ90 was released in 2004, being the first PDA to feature an OLED screen.[177] Other Sony products to feature OLED screens include the MZ-RH1 portable minidisc recorder, released in 2006[178] and the Walkman X Series.[179]

Lumiotec is the first company in the world developing and selling, since January 2011, mass-produced OLED lighting panels with such brightness and long lifetime. Lumiotec is a joint venture of Mitsubishi Heavy Industries, ROHM, Toppan Printing, and Mitsui & Co. On June 1, 2011, Mitsubishi Electric installed a 6-meter OLED 'sphere' in Tokyo's Science Museum.[204] In 1999, Kodak and Sanyo had entered into a partnership to jointly research, develop, and produce OLED displays. They announced the world's first 2.4-inch active-matrix, full-color OLED display in September the same year.[29] In September 2002, they presented a prototype of 15-inch HDTV format display based on white OLED with color filters at the CEATEC Japan.[30]

The heavy metal atom at the centre of these complexes exhibits strong spin-orbit coupling, facilitating intersystem crossing between singlet and triplet states. By using these phosphorescent materials, both singlet and triplet excitons will be able to decay radiatively, hence improving the internal quantum efficiency of the device compared to a standard OLED where only the singlet states will contribute to emission of light. 6:31OLEDWorks OLED light panel manufacturing.

而OLED显示黑色的时候可以直接关闭黑色区域的像素点,来达到几乎纯黑的效果。对比度指的是白色比黑色的比值,对比度越高画面颜色越浓,OLED理论对比度可以说是无穷(实际百万),这是LCD所达不到的。OLED technology is used in commercial applications such as displays for mobile phones and portable digital media players, car radios and digital cameras among others, as well as lighting.[131] Such portable display applications favor the high light output of OLEDs for readability in sunlight and their low power drain. Portable displays are also used intermittently, so the lower lifespan of organic displays is less of an issue. Prototypes have been made of flexible and rollable displays which use OLEDs' unique characteristics. Applications in flexible signs and lighting are also being developed.[132] OLED lighting offers several advantages over LED lighting, such as higher quality illumination, more diffuse light source, and panel shapes.[131] Philips Lighting have made OLED lighting samples under the brand name "Lumiblade" available online[133] and Novaled AG based in Dresden, Germany, introduced a line of OLED desk lamps called "Victory" in September, 2011.[134] AMOLED 是 Active-matrix organic light-emitting diode 的简写(主动矩阵有机发光二极体),而 AM 主动式矩阵体是指 OLED 背后的像素定址技术。由于 AMOLED 每个像素会自己发光,可独立控制,可实现更纯净的黑色以及更高的对比度。此外,在显示画面时关闭不需要的画素还可以降低功耗。由于萤幕模组内部层数较少,因此透光率也更好,有利于实现更高的亮度以及更广的可视角度。也因为AMOLED不需要 TFT的背光源,相较之下厚度较薄。但因为 AMOLED 是有机材料易老化,若某区块长期显示高亮度光源,易造成图像有残影印在萤幕上的视觉缺陷,被称为“烧屏”。因OLED 屏幕无法通过控制电压调整亮度(DC调光),PWM调光导致了高频率的频闪,部分人可能因此感到不适甚至对视觉有所损害。 Organic light emitting diodes (devices) or OLEDs are monolithic, solid-state devices that typically consist of a series of organic thin films sandwiched between two thin-film conductive electrodes

LG's entry-level OLED TV delivers flagship-level picture quality, making it the best high-end TV choice available By 2017, brands using LG OLED panels include Panasonic, Sony, Toshiba, Philips and Loewe.[203] On December 5, 2017, JOLED, the successor of Sony and Panasonic's printable OLED business units, began the world's first commercial shipment of inkjet printed OLED panels.[35][36] Molecules commonly used in OLEDs include organometallic chelates (for example Alq3, used in the organic light-emitting device reported by Tang et al.), fluorescent and phosphorescent dyes and conjugated dendrimers. A number of materials are used for their charge transport properties, for example triphenylamine and derivatives are commonly used as materials for hole transport layers.[50] Fluorescent dyes can be chosen to obtain light emission at different wavelengths, and compounds such as perylene, rubrene and quinacridone derivatives are often used.[51] Alq3 has been used as a green emitter, electron transport material and as a host for yellow and red emitting dyes.

Transfer-printing is an emerging technology to assemble large numbers of parallel OLED and AMOLED devices efficiently. It takes advantage of standard metal deposition, photolithography, and etching to create alignment marks commonly on glass or other device substrates. Thin polymer adhesive layers are applied to enhance resistance to particles and surface defects. Microscale ICs are transfer-printed onto the adhesive surface and then baked to fully cure adhesive layers. An additional photosensitive polymer layer is applied to the substrate to account for the topography caused by the printed ICs, reintroducing a flat surface. Photolithography and etching removes some polymer layers to uncover conductive pads on the ICs. Afterwards, the anode layer is applied to the device backplane to form bottom electrode. OLED layers are applied to the anode layer with conventional vapor deposition, and covered with a conductive metal electrode layer. As of 2011[update] transfer-printing was capable to print onto target substrates up to 500mm X 400mm. This size limit needs to expand for transfer-printing to become a common process for the fabrication of large OLED/AMOLED displays.[85] For a high resolution display like a TV, a TFT backplane is necessary to drive the pixels correctly. As of 2019, low temperature polycrystalline silicon (LTPS) – thin-film transistor (TFT) is widely used for commercial AMOLED displays. LTPS-TFT has variation of the performance in a display, so various compensation circuits have been reported.[87] Due to the size limitation of the excimer laser used for LTPS, the AMOLED size was limited. To cope with the hurdle related to the panel size, amorphous-silicon/microcrystalline-silicon backplanes have been reported with large display prototype demonstrations.[88] An IGZO backplane can also be used. /apps/mt/templates/esbu products --> 공정 분석 - 제품 - 메틀러 토레도환영합니다, {mt:userTitle/} {mt:lastName/}나의 mt.com로그아웃로그인/등록대한민국SearchStart search 홈 제품 & 솔루션실험실 저울On February 17, 2011, Sony announced its 25" (63.5 cm) OLED Professional Reference Monitor aimed at the Cinema and high end Drama Post Production market.[190]

屏幕的成像原理各位想必应该清楚了——屏幕由无数个点组成,每个点由红绿蓝三个子像素组成,每个像素点通过调整红绿蓝子像素的颜色配比来显示颜色,最终所有的像素点拼出你看见的画面。An organic light-emitting diode (OLED or Organic LED), also known as an organic EL (organic electroluminescent) diode,[1][2] is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compound that emits light in response to an electric current. This organic layer is situated between two electrodes; typically, at least one of these electrodes is transparent. OLEDs are used to create digital displays in devices such as television screens, computer monitors, portable systems such as smartphones, handheld game consoles and PDAs. A major area of research is the development of white OLED devices for use in solid-state lighting applications.[3][4][5] 모델명 : OLED88Z9KNA. 비교하기

传统的LCD屏幕采用的是RGB(红绿蓝)标准排列,RGB三个子像素点不论是大小还是个数都是相同的。而对于AMOLED来说,采用的是Pentile钻石像素排列,绿色像素点的数量是红蓝像素点的2倍,也就是RGBG排列。单个红蓝像素点面积要比绿色像素点要大。On January 8, 2013, at CES Samsung unveiled a unique curved 4K Ultra S9 OLED television, which they state provides an "IMAX-like experience" for viewers.[173] Apple began using OLED panels in its watches in 2015 and in its laptops in 2016 with the introduction of an OLED touchbar to the MacBook Pro.[209] In 2017, Apple announced the introduction of their tenth anniversary iPhone X with their own optimized OLED display licensed from Universal Display Corporation.[210] Apple has continued the use of the technology in the iPhone X's successors, such as the iPhone XS and iPhone XS Max, and iPhone 11 Pro and iPhone 11 Pro Max. At the 2007, Las Vegas Consumer Electronics Show (CES), Sony showcased a 11-inch (28 cm), (resolution 960×540) and 27-inch (69 cm), full HD resolution at 1920 × 1080 OLED TV models.[180] Both claimed 1,000,000:1 contrast ratios and total thicknesses (including bezels) of 5 mm. In April 2007, Sony announced it would manufacture 1000 11-inch (28 cm) OLED TVs per month for market testing purposes.[181] On October 1, 2007, Sony announced that the 11-inch (28 cm) model, now[when?] called the XEL-1, would be released commercially;[32] the XEL-1 was first released in Japan in December 2007.[182] During operation, a voltage is applied across the OLED such that the anode is positive with respect to the cathode. Anodes are picked based upon the quality of their optical transparency, electrical conductivity, and chemical stability.[42] A current of electrons flows through the device from cathode to anode, as electrons are injected into the LUMO of the organic layer at the cathode and withdrawn from the HOMO at the anode. This latter process may also be described as the injection of electron holes into the HOMO. Electrostatic forces bring the electrons and the holes towards each other and they recombine forming an exciton, a bound state of the electron and hole. This happens closer to the electron-transport layer part of the emissive layer, because in organic semiconductors holes are generally more mobile than electrons. The decay of this excited state results in a relaxation of the energy levels of the electron, accompanied by emission of radiation whose frequency is in the visible region. The frequency of this radiation depends on the band gap of the material, in this case the difference in energy between the HOMO and LUMO.

While an OLED will consume around 40% of the power of an LCD displaying an image that is primarily black, for the majority of images it will consume 60–80% of the power of an LCD. However, an OLED can use more than 300% power to display an image with a white background, such as a document or web site.[125] This can lead to reduced battery life in mobile devices when white backgrounds are used.

It is transparent to visible light and has a high work function which promotes injection of holes into the HOMO level of the organic layer. A second conductive (injection) layer is typically added, which may consist of PEDOT:PSS,[43] as the HOMO level of this material generally lies between the work function of ITO and the HOMO of other commonly used polymers, reducing the energy barriers for hole injection. Metals such as barium and calcium are often used for the cathode as they have low work functions which promote injection of electrons into the LUMO of the organic layer.[44] Such metals are reactive, so they require a capping layer of aluminium to avoid degradation. Two secondary benefits of the aluminum capping layer include robustness to electrical contacts and the back reflection of emitted light out to the transparent ITO layer.

By 2004, Samsung Display, a subsidiary of South Korea's largest conglomerate and a former Samsung-NEC joint venture, was the world's largest OLED manufacturer, producing 40% of the OLED displays made in the world,[160] and as of 2010, has a 98% share of the global AMOLED market.[161] The company is leading the world of OLED industry, generating $100.2 million out of the total $475 million revenues in the global OLED market in 2006.[162] As of 2006, it held more than 600 American patents and more than 2800 international patents, making it the largest owner of AMOLED technology patents.[162] In January 2015, LG Display signed a long-term agreement with Universal Display Corporation for the supply of OLED materials and the right to use their patented OLED emitters.[202]

On January 6, 2016, Dell announced the Ultrasharp UP3017Q OLED monitor at the Consumer Electronics Show in Las Vegas.[207] The monitor was announced to feature a 30-inch (76 cm) 4K UHD OLED panel with a 120 Hz refresh rate, 0.1 millisecond response time, and a contrast ratio of 400,000:1. The monitor was set to sell at a price of $4,999 and release in March, 2016, just a few months later. As the end of March rolled around, the monitor was not released to the market and Dell did not speak on reasons for the delay. Reports suggested that Dell canceled the monitor as the company was unhappy with the image quality of the OLED panel, especially the amount of color drift that it displayed when you viewed the monitor from the sides.[208] On April 13, 2017, Dell finally released the UP3017Q OLED monitor to the market at a price of $3,499 ($1,500 less than its original spoken price of $4,999 at CES 2016). In addition to the price drop, the monitor featured a 60 Hz refresh rate and a contrast ratio of 1,000,000:1. As of June, 2017, the monitor is no longer available to purchase from Dell's website. 그래픽 OLED 캐릭터 LCD 그래픽 LCD VFD 모듈 캐릭터 OLED 그래픽 OLED 세그먼트 LCD LCD,OLED 캐릭터 아두이노와 호환되는 0.96인치 OLED LCD 모듈입니다. 검은색 바탕 흰색 글씨 In October 2008, Sony published results of research it carried out with the Max Planck Institute over the possibility of mass-market bending displays, which could replace rigid LCDs and plasma screens. Eventually, bendable, see-through displays could be stacked to produce 3D images with much greater contrast ratios and viewing angles than existing products.[187] An OLED display works without a backlight because it emits visible light. Thus, it can display deep black levels and can be thinner and lighter than a liquid crystal display (LCD). In low ambient light conditions (such as a dark room), an OLED screen can achieve a higher contrast ratio than an LCD, regardless of whether the LCD uses cold cathode fluorescent lamps or an LED backlight. OLED displays are made in the same way as LCDs, but after TFT (for active matrix displays), addressable grid (for passive matrix displays) or ITO segment (for segment displays) formation, the display is coated with hole injection, transport and blocking layers, as well with electroluminescent material after the 2 first layers, after which ITO or metal may be applied again as a cathode and later the entire stack of materials is encapsulated. The TFT layer, addressable grid or ITO segments serve as or are connected to the anode, which may be made of ITO or metal.[7][8] OLEDs can be made flexible and transparent, with transparent displays being used in smartphones with optical fingerprint scanners and flexible displays being used in foldable smartphones. AMOLED屏幕由于Pentile排列的特殊性,像素密度还要打折到√(2/3),√(2/3)大概就是81.65%。这一折扣就是由于绿色像素点是红蓝像素点的2倍造成的。所以在分辨率相同的情况下,OLED的屏幕是不如LCD细腻的。而OLED要想显示效果更加细腻唯一的解决方法就是提高分辨率。

Polymer light-emitting diodes (PLED, P-OLED), also light-emitting polymers (LEP), involve an electroluminescent conductive polymer that emits light when connected to an external voltage. They are used as a thin film for full-spectrum colour displays. Polymer OLEDs are quite efficient and require a relatively small amount of power for the amount of light produced. DuPont stated in a press release in May 2010, that they can produce a 50-inch OLED TV in two minutes with a new printing technology. If this can be scaled up in terms of manufacturing, then the total cost of OLED TVs would be greatly reduced. DuPont also states that OLED TVs made with this less expensive technology can last up to 15 years if left on for a normal eight-hour day.[145][146] Textiles incorporating OLEDs are an innovation in the fashion world and pose for a way to integrate lighting to bring inert objects to a whole new level of fashion. The hope is to combine the comfort and low cost properties of textile with the OLEDs properties of illumination and low energy consumption. Although this scenario of illuminated clothing is highly plausible, challenges are still a road block. Some issues include: the lifetime of the OLED, rigidness of flexible foil substrates, and the lack of research in making more fabric like photonic textiles.[155] The OLED material used to produce blue light degrades much more rapidly than the materials used to produce other colors; in other words, blue light output will decrease relative to the other colors of light. This variation in the differential color output will change the color balance of the display, and is much more noticeable than a uniform decrease in overall luminance.[113] This can be avoided partially by adjusting the color balance, but this may require advanced control circuits and input from a knowledgeable user. More commonly, though, manufacturers optimize the size of the R, G and B subpixels to reduce the current density through the subpixel in order to equalize lifetime at full luminance. For example, a blue subpixel may be 100% larger than the green subpixel. The red subpixel may be 10% larger than the green. Various venders are also researching cameras under OLEDs (Under Display Cameras). According to IHS Markit Huawei has partnered with BOE, Oppo with China Star Optoelectronics Technology (CSOT), Xiaomi with Visionox.[215]

De LG OLED55C9PLA uit 2019 is een Ultra HD/4K oled televisie met een beeldschermdiagonaal van 140 cm (55 inch). Het is een Smart TV met onder meer apps voor Netflix en Youtube 首先我们得了解PPI(Pixels Per Inch)单位像素密度这个概念,PPI越高,屏幕显示效果越细腻,屏幕像素密度计算公式是PPI=√(X^2+Y^2)/ Z (X:长度像素数;Y:宽度像素数;Z:屏幕大小)

If there's been one problem with OLED TVs in general, it's that they've all been massive, with the smallest options still a hefty 55-inch. This year, things change and we got a hands-on look at the LG.. Typically, a polymer such as poly(N-vinylcarbazole) is used as a host material to which an organometallic complex is added as a dopant. Iridium complexes[66] such as Ir(mppy)3[64] are currently[when?] the focus of research, although complexes based on other heavy metals such as platinum[65] have also been used. 实际上,这个省电是有前提的,显示黑色画面的时长是关键,并且充满随机性,经过测试,看视频的情况下OLED的确更有优势,显示黑色内容也的确更省电,但是如果是亮色背景,LCD反而相对省电。总之就是OLED显示黑色不怎么耗电,LCD一直均匀耗电。

This makes the production process more expensive and of limited use for large-area devices, than other processing techniques. However, contrary to polymer-based devices, the vacuum deposition process enables the formation of well controlled, homogeneous films, and the construction of very complex multi-layer structures. This high flexibility in layer design, enabling distinct charge transport and charge blocking layers to be formed, is the main reason for the high efficiencies of the small molecule OLEDs. Samsung is sole supplier of costly 'iPhone 8' OLED, putting Apple in 'urgent need' of alternatives. Samsung still deliberating QD OLED production equipment specifications before issuing purchase.. Coherent emission from a laser dye-doped tandem SM-OLED device, excited in the pulsed regime, has been demonstrated.[52] The emission is nearly diffraction limited with a spectral width similar to that of broadband dye lasers.[53]

The Google and HTC Nexus One smartphone includes an AMOLED screen, as does HTC's own Desire and Legend phones. However, due to supply shortages of the Samsung-produced displays, certain HTC models will use Sony's SLCD displays in the future,[136] while the Google and Samsung Nexus S smartphone will use "Super Clear LCD" instead in some countries.[137] All OLED displays (passive and active matrix) use a driver IC, often mounted using Chip-on-glass (COG), using an Anisotropic conductive film.[73] Samsung's latest[when?] AMOLED smartphones use their Super AMOLED trademark, with the Samsung Wave S8500 and Samsung i9000 Galaxy S being launched in June 2010. In January 2011, Samsung announced their Super AMOLED Plus displays, which offer several advances over the older Super AMOLED displays: real stripe matrix (50% more sub pixels), thinner form factor, brighter image and an 18% reduction in energy consumption.[171] Vacuum deposition is not a suitable method for forming thin films of polymers. However, polymers can be processed in solution, and spin coating is a common method of depositing thin polymer films. This method is more suited to forming large-area films than thermal evaporation. No vacuum is required, and the emissive materials can also be applied on the substrate by a technique derived from commercial inkjet printing.[56][57] However, as the application of subsequent layers tends to dissolve those already present, formation of multilayer structures is difficult with these methods. The metal cathode may still need to be deposited by thermal evaporation in vacuum. An alternative method to vacuum deposition is to deposit a Langmuir-Blodgett film.

In 1960, Martin Pope and some of his co-workers at New York University developed ohmic dark-injecting electrode contacts to organic crystals.[13][14][15] They further described the necessary energetic requirements (work functions) for hole and electron injecting electrode contacts. These contacts are the basis of charge injection in all modern OLED devices. Pope's group also first observed direct current (DC) electroluminescence under vacuum on a single pure crystal of anthracene and on anthracene crystals doped with tetracene in 1963[16] using a small area silver electrode at 400 volts. The proposed mechanism was field-accelerated electron excitation of molecular fluorescence.

Originally, the most basic polymer OLEDs consisted of a single organic layer. One example was the first light-emitting device synthesised by J. H. Burroughes et al., which involved a single layer of poly(p-phenylene vinylene). However multilayer OLEDs can be fabricated with two or more layers in order to improve device efficiency. As well as conductive properties, different materials may be chosen to aid charge injection at electrodes by providing a more gradual electronic profile,[38] or block a charge from reaching the opposite electrode and being wasted.[39] Many modern OLEDs incorporate a simple bilayer structure, consisting of a conductive layer and an emissive layer. More recent[when?] developments in OLED architecture improves quantum efficiency (up to 19%) by using a graded heterojunction.[40] In the graded heterojunction architecture, the composition of hole and electron-transport materials varies continuously within the emissive layer with a dopant emitter. The graded heterojunction architecture combines the benefits of both conventional architectures by improving charge injection while simultaneously balancing charge transport within the emissive region.[41] A typical OLED is composed of a layer of organic materials situated between two electrodes, the anode and cathode, all deposited on a substrate. The organic molecules are electrically conductive as a result of delocalization of pi electrons caused by conjugation over part or all of the molecule. These materials have conductivity levels ranging from insulators to conductors, and are therefore considered organic semiconductors. The highest occupied and lowest unoccupied molecular orbitals (HOMO and LUMO) of organic semiconductors are analogous to the valence and conduction bands of inorganic semiconductors.[37] LCD打开就是整个背光层全部打开,所以LCD要么全开要么全关,而OLED每个像素点都是独立的,所以OLED可以单独点亮某些像素点,利用这个特性可以做到一个非常方便的功能——息屏提醒(Always on display),在屏幕关闭后,以低亮度点亮几个像素点来显示时间,电量,以及通知。Sony exhibited a 24.5" (62 cm) prototype OLED 3D television during the Consumer Electronics Show in January 2010.[188] OLED ve QLED nedir ?

Although the shadow-mask patterning method is a mature technology used from the first OLED manufacturing, it causes many issues like dark spot formation due to mask-substrate contact or misalignment of the pattern due to the deformation of shadow mask. Such defect formation can be regarded as trivial when the display size is small, however it causes serious issues when a large display is manufactured, which brings significant production yield loss. To circumvent such issues, white emission devices with 4-sub-pixel color filters (white, red, green and blue) have been used for large televisions. In spite of the light absorption by the color filter, state-of-the-art OLED televisions can reproduce color very well, such as 100% NTSC, and consume little power at the same time. This is done by using an emission spectrum with high human-eye sensitivity, special color filters with a low spectrum overlap, and performance tuning with color statistics into consideration.[81] This approach is also called the "Color-by-white" method. Water can instantly damage the organic materials of the displays. Therefore, improved sealing processes are important for practical manufacturing. Water damage especially may limit the longevity of more flexible displays.[123] 14+ 공정 기술. 미디어 처리는 고정 기능 유닛에서 인텔의 새로운 CPU인 7 세대 코어 프로세서(카비 AMD와 GF, 3.35억 달러의 웨이퍼 계약, 7nm 공정 개발.

A szadai réten 5 kilométeres körben lehet megcsodálni az egzotikus állatokat Experimental research has proven that the properties of the anode, specifically the anode/hole transport layer (HTL) interface topography plays a major role in the efficiency, performance, and lifetime of organic light-emitting diodes. Imperfections in the surface of the anode decrease anode-organic film interface adhesion, increase electrical resistance, and allow for more frequent formation of non-emissive dark spots in the OLED material adversely affecting lifetime. Mechanisms to decrease anode roughness for ITO/glass substrates include the use of thin films and self-assembled monolayers. Also, alternative substrates and anode materials are being considered to increase OLED performance and lifetime. Possible examples include single crystal sapphire substrates treated with gold (Au) film anodes yielding lower work functions, operating voltages, electrical resistance values, and increasing lifetime of OLEDs.[45]

Le LG OLED55C7V est un téléviseur connectée OLED de 55 pouces de diagonale avec une dalle très fine. Il dispose d'une image ultra haute définition (3840 x 2160 pixels) et d'un système WebOS 3.5. OLED stands for Organic LED. It is made of an organic material which emits light when current flows through it. OLEDs are always in OFF condition and each pixel is illuminated separately A Japanese manufacturer Pioneer Electronic Corporation produced the first car stereos with a monochrome OLED display, which was also the world's first OLED product.[156] André Bernanose and co-workers at the Nancy-Université in France made the first observations of electroluminescence in organic materials in the early 1950s. They applied high alternating voltages in air to materials such as acridine orange, either deposited on or dissolved in cellulose or cellophane thin films. The proposed mechanism was either direct excitation of the dye molecules or excitation of electrons.[9][10][11][12] Experimental OLED displays using conventional photolithography techniques instead of FMMs have been demonstrated, allowing for large substrate sizes (as it eliminates the need for a mask that needs to be as large as the substate) and good yield control.[86]

In May 2008, Samsung unveiled an ultra-thin 12.1 inch (30 cm) laptop OLED display concept, with a 1,280×768 resolution with infinite contrast ratio.[165] According to Woo Jong Lee, Vice President of the Mobile Display Marketing Team at Samsung SDI, the company expected OLED displays to be used in notebook PCs as soon as 2010.[166] Like ink jet material depositioning, inkjet etching (IJE) deposits precise amounts of solvent onto a substrate designed to selectively dissolve the substrate material and induce a structure or pattern. Inkjet etching of polymer layers in OLED's can be used to increase the overall out-coupling efficiency. In OLEDs, light produced from the emissive layers of the OLED is partially transmitted out of the device and partially trapped inside the device by total internal reflection (TIR). This trapped light is wave-guided along the interior of the device until it reaches an edge where it is dissipated by either absorption or emission. Inkjet etching can be used to selectively alter the polymeric layers of OLED structures to decrease overall TIR and increase out-coupling efficiency of the OLED. Compared to a non-etched polymer layer, the structured polymer layer in the OLED structure from the IJE process helps to decrease the TIR of the OLED device. IJE solvents are commonly organic instead of water-based due to their non-acidic nature and ability to effectively dissolve materials at temperatures under the boiling point of water.[84] Organic Light Emitting Diode 유기 발광 다이오드.

Improvements to the efficiency and lifetime of blue OLEDs is vital to the success of OLEDs as replacements for LCD technology. Considerable research has been invested in developing blue OLEDs with high external quantum efficiency, as well as a deeper blue color.[114][115][116] External quantum efficiency values of 20% and 19% have been reported for red (625 nm) and green (530 nm) diodes, respectively.[117][118] However, blue diodes (430 nm) have only been able to achieve maximum external quantum efficiencies in the range of 4% to 6%.[119]

屏幕是需要控制亮度的,对于LCD,我们直接通过调整背光层的电压就能控制亮度(DC调光),而OLED在低电压下会出现不均匀的果冻效应,所以OLED就不能采取控制电压调整亮度,OLED控制亮度的方法就是不断的开关开关开关,开关的频率高到一定程度了肉眼就无法看出来了(PWM调光)。Typical polymers used in PLED displays include derivatives of poly(p-phenylene vinylene) and polyfluorene. Substitution of side chains onto the polymer backbone may determine the colour of emitted light[58] or the stability and solubility of the polymer for performance and ease of processing.[59] While unsubstituted poly(p-phenylene vinylene) (PPV) is typically insoluble, a number of PPVs and related poly(naphthalene vinylene)s (PNVs) that are soluble in organic solvents or water have been prepared via ring opening metathesis polymerization.[60][61][62] These water-soluble polymers or conjugated poly electrolytes (CPEs) also can be used as hole injection layers alone or in combination with nanoparticles like graphene.[63] 1.

The use of OLEDs may be subject to patents held by Universal Display Corporation, Eastman Kodak, DuPont, General Electric, Royal Philips Electronics, numerous universities and others.[147] There are by now[when?] thousands of patents associated with OLEDs, both from larger corporations and smaller technology companies.[37] Samsung introduced the Galaxy Round smartphone in the Korean market in October 2013. The device features a 1080p screen, measuring 5.7 inches (14 cm), that curves on the vertical axis in a rounded case. The corporation has promoted the following advantages: A new feature called "Round Interaction" that allows users to look at information by tilting the handset on a flat surface with the screen off, and the feel of one continuous transition when the user switches between home screens.[176] Dual panel or dual layer LCDs may be used instead of OLEDs, since OLEDs are difficult and expensive to make, unlike LCDs. Organic vapour jet printing (OVJP) uses an inert carrier gas, such as argon or nitrogen, to transport evaporated organic molecules (as in organic vapour phase deposition). The gas is expelled through a micrometre-sized nozzle or nozzle array close to the substrate as it is being translated. This allows printing arbitrary multilayer patterns without the use of solvents. The Sony XEL-1, released in 2007, was the first OLED television.[32] Universal Display Corporation, one of the OLED materials companies, holds a number of patents concerning the commercialization of OLEDs that are used by major OLED manufacturers around the world.[33][34]

The biggest technical problem for OLEDs is the limited lifetime of the organic materials. One 2008 technical report on an OLED TV panel found that after 1,000 hours, the blue luminance degraded by 12%, the red by 7% and the green by 8%.[95] In particular, blue OLEDs historically have had a lifetime of around 14,000 hours to half original brightness (five years at eight hours per day) when used for flat-panel displays. This is lower than the typical lifetime of LCD, LED or PDP technology; each currently[when?] is rated for about 25,000–40,000 hours to half brightness, depending on manufacturer and model. One major challenge for OLED displays is the formation of dark spots due to the ingress of oxygen and moisture, which degrades the organic material over time whether or not the display is powered.[96][97][98] In 2016, LG Electronics reported an expected lifetime of 100,000 hours, up from 36,000 hours in 2013.[99] A US Department of Energy paper shows that the expected lifespans of OLED lighting products goes down with increasing brightness, with an expected lifespan of 40,000 hours at 25% brightness, or 10,000 hours at 100% brightness.[100] 공정 신뢰성 향상운영 가동 시간 증가ISM은 센서 상태에 대한 실시간 정보를 제공하여 최고의 효율성으로 생산 운영을 하는 데 도움이 됩니다.Degradation occurs because of the accumulation of nonradiative recombination centers and luminescence quenchers in the emissive zone.

Nokia introduced OLED mobile phones including the N85 and the N86 8MP, both of which feature an AMOLED display. OLEDs have also been used in most Motorola and Samsung color cell phones, as well as some HTC, LG and Sony Ericsson models.[135] OLED technology can also be found in digital media players such as the Creative ZEN V, the iriver clix, the Zune HD and the Sony Walkman X Series. Research into polymer electroluminescence culminated in 1990, with J. H. Burroughes et al. at the Cavendish Laboratory at Cambridge University, UK, reporting a high-efficiency green light-emitting polymer-based device using 100 nm thick films of poly(p-phenylene vinylene).[26] Moving from molecular to macromolecular materials solved the problems previously encountered with the long-term stability of the organic films and enabled high-quality films to be easily made.[27] Subsequent research developed multilayer polymers and the new field of plastic electronics and OLED research and device production grew rapidly.[28] On September 6, 2013, Samsung launched its 55-inch curved OLED TV (model KE55S9C) in the United Kingdom with John Lewis.[175]
