However, OLED displays are light and thin, colorful, power-saving, and can achieve full screen, etc., but also have branding, color decay speed, short life, considerable power consumption when white light, and panel damage Unrepairable, costly, etc.. Therefore, the price of smart phone products using OLED displays is relatively higher than that of LCD monitors, and OLEDs are encountered in the future when they enter the 4K, 8K ultra-high image quality era. The technical bottleneck will make it 'noble' to be accepted by smartphone manufacturers or consumers.
Dai Zhenjia, general manager of Taiwan's Nichia (NICHIA), said that Apple's smart phones use OLED displays, which have certain impacts and challenges on the LED market. However, LCD backlights and LCD panels are quite mature technologies, although in wisdom. On the full screen performance of the mobile phone, the LCD display still has to leave a 4~4.5mm frame. If the OLED display can be designed with almost no border, the LDC display and LED technology will continue to evolve and will catch up with the OLED display. Leading distance.
In fact, Nissan Chemical's new LCD backlight product NTSV can further reduce the LCD display frame. Nichia's second department technology chief, Sakamoto Kazuo, said that the company's latest LCD backlight technology NTSV can do LCD The display frame is reduced from the traditional 4~45.mm to 2~2.5mm, which is quite close to the OLED display, and the picture quality is quite delicate. In addition, since the LCD backlight and LCD display are mature technologies, it is bound to be cost. It has advantages over OLED. At present, a mobile phone manufacturing company has adopted Nichia Chemicals NTSV LCD backlight products to develop new mobile phones.
Not only that, LCD monitors have absolute lead in 4K, 8K, and even 10K quality display. Dai Zhenjia said that LCD TVs can now display 4K quality, and 8K TVs will be listed at the end of 2018. OLED, currently only Samsung (Samsung) can achieve 4K quality OLED display. OLED display to 8K, 10K, technical challenges are quite high, and even if you overcome various technical challenges, make an OLED display that can display 8K quality, but The cost can be prohibitively high.
In the future, the 5G era will enter the 5G era. The high transmission rate of 5G will allow more high-quality images and video to be streamed between various smart devices. At this time, LCD and OLED displays stand out, and OLED displays will eventually It may not be the mainstream of smart phone displays. Dai Zhenjia stressed that there are still many functions of LCD monitors that have not been developed. In the technological development, LCD monitors have gradually caught up, and will soon surpass OLED displays.
Faced with the grim market situation of LEDs and the prospects for industry, Dai Zhenjia believes that Nichia has adopted the newly released three technologies - allowing LCD backlights to stabilize NTSV in the smart phone display market; Optisolis LEDs close to natural light can take advantage of areas such as medical, planting, indoor lighting, etc., and GigaWhite, which will change the design of automotive headlights, will continue to win market opportunities.
