Samsung grabs micro LED technology, apple strives for OLED screen

on December 14, it was reported that Samsung wanted to tap into Taiwan's Micro led supply chain and open a definition: a new round of panel war parallel to the back plate of the disc brake pad or the rim surface of the drum brake shoe. JDI pushed up the LCD for fine VR and accelerated the research and development of 1000ppi products. The University of Hong Kong is expected to break the monopoly of European and American patents by taking the lead in the research and development of OLED luminous raw materials. Apple invests in LG for OLED screen What are the important contents of today's display industry that deserve attention? Let's learn more

panel war starts, Samsung competes for micro LED technology and talents across the sea

Samsung recently increased its cooperation with Taiwan's Micro led supply chain, which has attracted great attention of Hon Hai group. Samsung has made a lot of money with OLED display technology this year, and now it has to poach Taiwan's Micro LED supply chain. Gou can no longer sit back and watch, and a new wave of panel war is about to begin

according to Caixun, Samsung Electronics of South Korea is racing against time to show micro LED TV at CES (American consumer electronics exhibition) on January 7, 2018. In particular, part of the supply chain that produces related products this time comes from Taiwan

in the past year, Korean manufacturers often visited Taiwan's Micro led supply chain. An industry person observed that Korean engineers often appear in Taiwan's Taiyuan Science and technology park. Wu Zhiyi, director of the Institute of Electro Optics of the Industrial Research Institute, pointed out that many audience members of the micro led forum hosted by the Industrial Research Institute this year were almost experts from Samsung and LG, and frequently asked questions. Zhou Mingjun, general manager of crystal, also said, "if Samsung pushes the insulating layer made of inorganic materials to produce micro led TVs next year, don't be too surprised."

according to Caixun, why is SamSung of South Korea so concerned about Taiwan's technological development? Because Samsung found that Taiwan's supply chain has independently and successfully manufactured a new type of display with a resolution of 300dpi full-color display information outside apple. As long as the soft substrate is replaced, it is possible to make a flexible display screen or a transparent new type of display to compete with Samsung in the market

in Taiwan, a considerable number of teams have invested in the research and development of micro led, an innovative technology. Only if this technology wants to play its value, display technology alone is not enough. It also needs customized display drive IC, mechanism and circuit to show its value. Samsung has all these resources

when Apple set up a secret R & D base in Longtan, Taiwan, to build a micro led supply chain, Samsung also secretly trained in-house. In the past year, Samsung also built micro led supply in Taiwan, but the state has given us many standard chains. The industry believes that the micro LED TV Samsung wants has entered the final stage

at present, elux, a micro led company newly invested by Terry Gou, is cooperating with rongchuang, a subsidiary of Hon Hai. At the same time, sharp, led by Dai Zhengwu, will also study whether micro LED technology can be combined with sharp's proud igzo (thin film transistor) technology to make high-level display panels. According to the survey of Caixun, at present, the sub groups under Hon Hai also invest with their own funds, such as the automotive business department, and actively want to apply this technology to the automotive industry

JDI promotes the development of LCD for fine VR and accelerates the research and development of 1000ppi products

Japan display Inc (JDI), a large manufacturer of small and medium-sized LCD panels in Japan, announced on the 12th that it has developed LCD panel products for virtual reality (VR) head mounted displays (HMDS) with the highest level in the world. This VR LCD panel has a size of 3.6 inches and a resolution of 1920 × RGB × 2160, the PPI (pixel per inch) used to display clarity is 803, higher than 651ppi of JDI's current products. The sample of this product is expected to be delivered in the spring of 2018, and the target is to start mass production in 2018

jdi also pointed out that it will speed up the research and development of liquid crystal panels for VR, and is expected to complete the research and development of panels with a fineness of more than 1000ppi in the first half of 2018

Nikkei reported that OLED panels are the mainstream of the current VR machine panels, and JDI hopes to expand the above new panel orders and fight against OLED panels by using technologies superior to its competitors. It is reported that Sony PSVR and other VR machines use OLED panels with fast response speed, and JDI has made the response speed of LCD panels comparable to the level of OLED panels, and will also make proposals to VR machine manufacturers in the future

displayhdr 1.0 standard release

hdr (high dynamic range) is undoubtedly a popular technology in the display field in recent years. More and more monitors, TVs and screens begin to support HDR technology, which can bring better contrast, brightness and color accuracy than traditional SDR

in terms of technical standards, there are open hdr-10 and patented Dolby vision in the television field. VESA (Video Electronic Standards Association) has now launched the first new HDR technical standard for PC displays - displayhdr 1.0

displayhdr standard was formulated with the participation of more than 20 chip, display panel, display, PC and system manufacturers in the industry, including Intel, AMD, NVIDIA, Microsoft, analogix, JDI, LG, LG display, Samsung, Youda optoelectronics, Innolux, ASUS, Dell, HP, Lenovo, Morningstar, Realtek, megachips, portrait displays, etc


displayhdr 1.0 standard is for LCD liquid crystal displays that occupy more than 99% of the market products. It defines three different levels. The requirements for the brightness, color gamut, color depth and other specifications of the display are different, but they must have a true 8-bit color display panel (the market share is about 15%):

displayhdr 400 is the lowest end, and it is required to support global dimming, with a peak brightness of not less than 400nit and a global continuous brightness of not less than 320nit, ITU-R bt.709 color gamut (basically similar to sRGB color gamut) covers not less than 95%, and supports hdr-10

displayhdr 600 for high-end displays and notebooks, the screen is required to have a 10 bit processing capacity, a peak brightness of 600nit, a continuous brightness of 350nit, a black-and-white brightness response time of no more than 8 frames, and a color gamut covering 99% ITU-R bt.709, 90% dci-p3 65

displayhdr 1000 is only competent for professional displays, with a peak brightness of 1000nit and a continuous brightness of 600nit. At the same time, the color gamma of color building benchmarking enterprise has been significantly improved

if you want to buy HDR monitors in the future, you can judge according to the above three certification levels
