Several major trends of display screen in 2017: OLED, HDR and flexible LCD

the battle between LCD and AMOLED has been going on for a long time. However, in the industry, a large number of industry experts and machine friends are inclined to AMOLED, believing that it can provide higher display quality and change into various forms, which is a great technological progress. So, AMOLED flexible screen has come out, does it mean that there is no flexible LCD screen to compete with in the future? Not so

2016 is the most critical year in the battle between AMOLED and LCD screens. Because at the size level of 5 inches, the price of AMOLED panels has fallen to the same level as LCD. Over the years, the advantage of lower LCD manufacturing costs has gradually lost. A large number of manufacturers have begun to choose display panels that are cost-effective, especially the listing of display technology and quality, which puts greater pressure on the supply chain

amoled ushered in huge growth

there are many data on this point. For example, the report from Taiwan's supply chain predicts that the shipment of flexible AMOLED panels increased by 200% in 2017, with at least 150million panels shipped, compared with 50million last year. There are also some conservative reports that AMOLED shipments increased by at least 50% in 2017. Even so, this is still a considerable number, because manufacturers no longer need to only look at Samsung's face to build products

according to insiders, sharp under Foxconn is planning to invest 100billion yen in OLED production lines, an increase of about 0.35% compared with the previous investment. At the same time, it is constantly believed that Apple's exclusive investment is as high as $7billion to help build the display production line, but it has not been confirmed yet. However, considering that Apple's iPhone will be fully migrated to the OLED product line, the supply guarantee must be the foundation

LG, Samsung's main competitor, also reportedly invested $1.75 billion last year to establish a flexible OLED production line. Some leaked regulatory documents show that LG will mass produce small to medium-sized flexible OLED panels to meet the demand. In any case, Samsung and LG are significantly more focused on OLED than LCD, and even far more than their competitors. At this speed, it is inevitable that LCD screens will be replaced by OLED screens in the next few years

in Chinese Mainland, Tianma microelectronics, BOE, vicino and other manufacturers also hope to expand AMOLED production capacity and get rid of Samsung as soon as possible. According to the research report from DIGITIMES, the total production capacity of OLED panels in the mainland can be expanded from 272000 square meters to square meters by 2018, which is expected to reach square meters in 2019 and rise to square meters in 2020. Considering that the total capacity of Samsung and LG in 2016 is square meters, and it is expected to be square meters in 2020, the gap between domestic panel manufacturers will be smaller and smaller

it has to be said that OLED panels have become the new darling of the display industry, and the investment in LCD technology has slowed down. But that said, the market still needs competition, and the LCD panel technology will not let AMOLED take the lead

flexible LCD panel comes out

everyone who pays attention to the TV industry knows that quantum dot technology can help improve the brightness and contrast of LCD screen and bring a broader color gamut. Therefore, quantum dots are also regarded by the industry as the key technology to promote the growth of HDR LCD panels in the future. Of course, LCD also has a new technology for the advantages of OLED, that is, flexible LCD display panel

in January, JDI released a 5.5-inch 1080p LCD panel full active flex. Its most special feature is that it can bend like Samsung and LG flexible panels, so manufacturers can build products like S7 edge based on this panel. It should be noted that this flexible technology mainly benefits from the realization of the plastic substrate of the liquid crystal layer. The whole glass substrate is discarded, so the flexible curvature is higher, it can be bent and expanded freely, and it is not easy to break when falling accidentally

jdi plans to start mass production of full active flex panels in 2018, and there are already customers waiting in line. It is estimated that the domestic TPU demand has reached 400000 tons, but the list cannot be disclosed. Therefore, it can be predicted that there will be more relevant information about flexible LCD panels in the second half of this year

4k is good, but HDR is a new pursuit.

Sony xperiaz5 is the world's leading intelligent device equipped with 4K resolution display. There is no doubt about this, but no more manufacturers have been involved since then, mainly because of the high cost and the impact on endurance. Now, manufacturers are turning to the screen of HDR high dynamic range technology, which enables the content displayed to restore more realistic bright colors and contrast

the most basic performance requirements of HDR technology are the brightness and contrast of the panel, otherwise it is difficult to show a real dynamic range. Of course, realistic brightness is unlikely, but at least it can reach the brightness level captured by the shooting device. At present, the high brightness of OLED is basically suitable for this. Quantum dot LCD technology is also a feasible solution. With a panel, the next step is the support of software technology and graphics performance

snapdragon 835 flagship chip released by Qualcomm currently supports a maximum of 10 bit color depth, so it can greatly increase the color range of red, green, blue and how to choose the experimental machine. Black and white color range is the concern of most users. The 1.07 billion colors in different tones displayed on the screen is not a problem, which is greatly improved compared with 16million colors in 8-bit color depth. With this and the new panel technology, many manufacturers can really create a wide color gamut with HDR technology

at present, many signs indicate that smart manufacturers do not intend to further improve the screen resolution, but still maintain 2560 × The level of 1440 pixels can be said that 4K is not the final demand this year. Therefore, after snapdragon 835 ships in the second quarter, a large number of HDR technology screens will appear in the second half of the year. Manufacturers will carry out a lot of marketing publicity for this technology and produce HDR content for mobile devices

vr virtual reality industry is eager to try

vr virtual reality is an area generally favored by industry experts, and machine friends are also quite looking forward to it. This market will certainly grow further in 2017, and the smart screen built around vr virtual reality will become a key component to provide excellent experience. Not surprisingly, the screen of the next generation of VR devices will be characterized by high pixel density, ultra-high refresh rate and ultra-low delay, and may also bring new sub-pixel layout, HDR technology and wide color gamut

at present, the daydream VR platform, which is relatively unified in the industry, is likely to embrace OLED display panels, but thanks to the improvement of the new LCD technology, it will also become one of the options. Under the new technology, the backlight flicker rate of LCD screen will be greatly reduced. At the same time, the delay of black-and-white switching process can also be reduced to the same level as OLED. Whether the refresh rate is high enough will no longer be a big problem for the panel

in the fourth quarter of last year, sharp and JDI both released high-resolution LCD display panels specifically for vr virtual display. Maybe this year we will see the advent of virtual reality products based on this kind of LCD panel. At that time, it may be some independent vr virtual reality headsets, or manufacturers for VR intelligence or accessories. In any case, the new display technology will have a certain impact on the promotion of the VR industry this year, and perhaps this influence will continue for a longer time

2017 display trend

based on the above, it can be predicted that the technology of mobile display screen will continue to develop in a horizontal way in 2017, rather than the rapid development of high resolution. We can expect more AMOLED smart bursts this year, and with the increase of production capacity, AMOLED screens will not only be the patents of high-end flagship, but also cover medium and low-end models

at the same time, high-end equipment may be more inclined to develop HDR technology and the form of large and small curved surface of soft post measurement output, so as to stand out in the fierce competition. LCD will definitely not decline at this point. At the same time, new technological improvements will prove that it still has the characteristics that are not inferior to OLED panels, and can meet the needs of more equipment manufacturers
