As OLED display technology has become the new darling of high-end mobile phones, LCD will not stop there. LCD is still the most mature display technology at present, and there are many more technologies to be developed waiting for the investment of major manufacturers to achieve display quality comparable to OLED. Especially when moving towards 4K or 8K high image quality, LCD has the advantage of lower cost, so it can realize this vision faster than OLED.

Taiwan Nichia Chemical General Manager Dai Zhenjia pointed out that the company’s primary goal before 2019 is to launch its own LCD backlight product NTSV (Nichia Thin Side View) based on a nearly full screen 4K high-definition mobile phone with a narrow bezel.

Dai Zhen’s family shared that from 2016 to the present, the competition in the LED industry market has been very severe. After Apple introduced OLED display technology into smartphones in 2017, the market has become even more important. The change. In 2018, the market demand in the first two quarters was not strong, and the traditional LED backlight market also experienced overcapacity, causing many people to worry about the industry prospects.

Nevertheless, Dai Zhen’s family is still very optimistic about the development of LCD display technology in the future. He pointed out that in the small-size display market, although OLED has become the first choice for high-end smart phones at present, if the future is To progress to 4K and 8K high-definition displays, the high cost will be a very big challenge for OLED; in the large screen market such as TVs, 4K high-definition LCD TVs are now quite popular, and by the end of 2018, there will be more opportunities Seeing the official mass production of 8K products, however, LCD for Samsung is still unable to achieve 4K image quality. Therefore, it seems that, in the direction of progress towards 4K and 8K ultra-high image quality, LCD is a more mature technology than OLED technology, and its cost is relatively more competitive.

In the next two years, LCD display technology will also have more breakthroughs. Dai Zhen's family shared that in 2019, Nichia hopes to expand the application of LCD point light sources to surface light source applications. The Mini LED backlight, which has recently been hotly discussed, is one of the applications of surface light sources.

At the same time, in order to respond to the diversified needs of customers, Nichia has designed and developed LED products that are easy for customers to use, and maintains a smooth communication channel with customers. Recently, Nichia jointly invested in the establishment of a new company in South China. 'Optical Core Vision Technology Co., Ltd.' to provide a comprehensive solution for vertical integration.
