Starting in 2017, the display market is destined to launch a battle on mainstream display technology in the future. The two sides of the war are the OLED camp and the QLED camp. Judging from the current trend, the intensity of this battle will not be as good as that of the liquid crystal and plasma. In the end, the liquid crystal technology won the plasma and occupied the display market for nearly two decades. The world's major manufacturers have invested heavily in research and development of new technologies. The exact battle of the deceased is the "one mountain can not be two tigers", or "equal split", not yet known. Every 1° sister was confused by the technical terms when she saw the relevant information. She couldn’t help but feel the blood pressure soaring. This is really difficult for me to be a non-technical woman and a non-technical house. But how can such a wonderful drama be out of the way? ! So I painfully tried to uncover the veil of these "high on the" nouns, and sorted out some of the company's related information, I hope that my work can play a role in "bringing bricks and jade", readers can rely on their own interests, in this article Related content to carry out personalized extracurricular deep learning. Display classification LCDLCD is the most mature display panel product with the most stable technical performance and the largest output. The structure of the LCD is relatively complicated. The upper and lower layers are glass substrates that function as polarization, and the middle layer is composed of a thin film transistor (TFT) and a color filter (C/F Glass). The thin film transistor controls the polymer liquid crystal material through signal and voltage changes. Display effect. The LCD essentially emits different colors by selectively passing the backlight through the optical polarization characteristics of different molecular chains and functional groups in the liquid crystal material, so the polarizing filter can reduce the light source efficiency of the LCD by at least 50%. In addition, the color gamut and viewing angle of the LCD are its disadvantages. OLEDOLED technology is maturing and costs are decreasing, but it is still about 20% more expensive than LCD. The organic fluorescent layer in the OLED receives the signal emitted by the TFT, and can independently emit light of different colors, which is different from the passive filtering of the backlight in the LCD, so the OLED is in contrast, full color, light efficiency, refresh frequency, There are obvious advantages in terms of viewing angle. The device structure of QLEDQLED is similar to that of OLED, except that the organic polymer layer is replaced by a quantum dot material film. The unique properties of quantum dots are based on its own quantum effects, and when the particle size enters the nanometer order, it exhibits many physicochemical properties different from macroscopic materials. Whenever a quantum dot is stimulated by light or electricity, the quantum dot emits colored light. The color of the light is determined by the composition and size of the quantum dot. This feature allows the quantum dot to change the color of the light emitted by the light source. Quantum dots can completely convert the blue light emitted by the LED light source into white light, and the efficient performance makes it better in energy saving and emission reduction. In addition, AMQLED can achieve full color display with a color gamut of more than 100%. Compared with AMOLED, it has the potential advantages of long life, wide color gamut and low cost. Especially in the field of large-size active illuminating display, AMQLED has more advantages than AMOLED. Understand the structural characteristics of OLED and QLED, let's look at the layout of the two manufacturers in terms of these two displays. QLED camp 1, Samsung Speaking of global display manufacturers, Samsung has to mention one, because Samsung is a company that "foot on two boats." Both the OLED business and the QLED display industry. 2, TCL TCL's high-end brand XESS third-generation inorganic three-primary quantum dot TV has achieved 110% NTSC color gamut coverage due to the use of inorganic three-primary quantum dot display materials, achieving accurate restoration of 1.07 billion colors, and color purity compared to ordinary LEDs. Increased by 58.3%. TCL categorizes the main points of popular quantum dot TV into four aspects: one is to reduce costs, to make the cost of quantum TV and the cost of ordinary TV reach a basically consistent level; the second is to make quantum dot TV thinner; the third is from image quality, Layout of color gamut and color stability; Fourth, continuous promotion of printing technology, has achieved the production of screens like printed newspapers. TCL has invested billions of dollars in quantum dot technology. Nowadays, it is using the existing OLED materials to practice printing technology, and gradually realize the application of quantum dot technology, and plans to realize the commercialization of quantum dot technology for five years. 3. Hisense Hisense chose the technical route of ULED+ quantum dots. (ULED uses blue light chip to excite red and green phosphors or quantum dots. Through the study of the spectral distribution of hundreds of LED backlight spectra and dozens of color filters, a simulation model of the color gamut of the liquid crystal module is established and passed. Thousands of experimental data were optimized to design relatively good color filters and high color gamut LED backlight spectra.) ULED can obtain more accurate backlight, and quantum dot is a very good color gamut enhancement technology. The color gamut is flat and the brightness is deep. The combination of the two can enhance the three-dimensional color space and obtain more real. visual effect. Hisense's series of ULED super-quality TV sets combine the strengths of these two points and become representative products of LCD TVs. It is also another milestone product of Hisense's promotion of LCD display technology upgrade. OLED camp 1, LG At the recent 5th China Electronic Information Expo, LG Display demonstrated its ultra-thin design of 65-inch Wallpaper OLED products with a thickness of only 3mm, which can be attached to the wall like wallpaper. . It also shows the Crystal Sound OLED product itself as a stereo, 77-inch UHD double-sided display and a cylindrical commercial display with 6 UHD 77-inch screens. These exhibits demonstrate the application possibilities of OLEDs in a variety of application scenarios. South Korea's "Electronic Times" quoted an unnamed news that Google has proposed at least 1 trillion won (about 880.29 million US dollars) to help LG monitors increase the output of OLED screens used in smart phones. Google hopes to use this investment to establish a strategic partnership with LG Display. OLED screens are currently in short supply, and Google hopes to give priority to the supply of OLED screens and stabilize supply and demand. 2, Skyworth As the first color TV manufacturer to launch OLED TV in China, Skyworth took the lead in mass production of 4K OLED organic TV S9300 in August 2015. It acquired OLED TV in mass production in Europe after acquiring Metz in Germany in 2015, becoming the second brand to launch OLED products in the European market after LGD. In addition to continuing to expand the market coverage of OLEDs, Skyworth also launched the world's first OLED organic TV S9D equipped with AR technology in August 2016. The S9D won the Epland Award, which is known as the "Oscar of China's home appliance industry". 3. Changhong Sichuan Changhong Group invested 705 million yuan in the Hongshi OLED project, which is China's first complete OLED screen production line and a new move to accelerate the development of the third generation of display technology. The Hongshi OLED project was completed and put into production in the first quarter of 2009. After completion, it will form an annual production capacity of 12 million OLED display screens, ranking among the top OLED industry in the world. 4, Konka Konka bets on OLED technology in the face of the general trend and is a leader in the promotion and application of the industry. As early as 2013, it launched the first curved OLED TV in China, setting a new historical record. After five years of hard work, Konka has not only become the main force in the promotion and application of OLED technology, but also brought the initial maturity of OLED technology to the whole industry. 5, Sony Panasonic Sony, Panasonic and Japan Innovation Network Inc. (INCJ) and Japan Display Corporation (JDI) jointly established JOLED Inc. in 2015. The goal is to integrate Sony and Panasonic's OLED display technologies, including the use of printed production technology, transparent amorphous oxide thin film semiconductors, and flexible display technology. JOLED will focus on developing medium-sized OLED displays for tablets, mobile PCs and boot screens. 6, Philips According to data from Avi Cloud (AVC), the volume of Philips TV retail sales in 2016 was 2.574 million units, up 128.1% year-on-year; the retail sales volume was 5.84 billion yuan, up 119.5% year-on-year. The Philips 9 Series Ambilight OLED TV is amazing in the TV industry with its OLED display technology and other related technologies. According to the relevant person in charge of Philips TV, the future OLED TV will be Philips' key force model, continuing the high-end route and boutique route to create the real Philips "Sanhao TV". Summary In general, OLED has taken the lead in people's field of vision. The concept of "OLED stands for next-generation display technology" has been accepted by most people. Compared with QLED, the biggest advantage of OLED is that its technology is mature, the cost of products is declining, the quality defects of products are improving, and most mainstream companies in the world have entered the OLED camp. But in this way, the winners and losers have been divided? Actually not. The transformation of the giant company Samsung or the "two-pronged" strategy has made the OLED side not sure to completely eat QLED. The advantages of OLED are mainly reflected in the morphological diversity of products. However, the existing quantum dot TV relies on the basis of LCD, and has the advantages of mature technology, low price and complete industrial chain. It can be said that the two parties are evenly matched. In the future development, OLED urgently needs to solve the problems of output, product yield and service life, and further compress the development space of QLED, and QLED urgently needs to launch a true quantum dot TV-electroluminescence quantum dot TV. Get rid of the saying that "QLED TV is just a technical upgrade of LCD", and improve the bottom of the quantum dot camp. For our consumers, the battle of manufacturers will bring better products, better experience, more favorable prices, and we are optimistic.
