>> Chinese Academy of Sciences Ouyang Zhongcan: OLED may not be able to replace the LCD 19th,June,2017
At present, OLED continues to move forward, to a higher resolution and flexible direction evolution; LCD also innovation, to higher clarity, larger size, low cost direction. OLED and LCD who with Commander? Does OLED really replace LCD? In the June 23 at the "2016 cross-strait (Nanjing) new display industry Summit Forum", the Chinese Academy of Sciences Ouyang Zhongcan pointed out that OLED and LCD have room for development.
"Now the controversy about OLED and LCD is not the first time." Ouyang Zhongcan said, "years ago, an economist all day talking about OLED to replace the LCD, and later found him to speculation 'fire' stock market. There are stock analysts in speculation that OLEDs are going to replace LCD.
At present, the domestic on the OLED TV and quantum dots TV controversy, on behalf of the enterprise is Skyworth TCL. It is reported that Samsung will skip OLED TV directly into QLED. The DisplaySearch recently released the report shows that in 2015 ~ 2019, OLED market will be 93.4% compound annual growth rate. Skyworth said that in 2016 only Skyworth OLED TV sales can grow 10 times, by 2019, OLED products will replace the LCD TV, become the mainstream of color TV market.
Ouyang Zhongcan stressed that three years ago, Samsung claimed to do OLED TV, but now Samsung did not immediately implement the OLED TV program, but to do the quantum point of the TV, more inclined to LCD.
"OLED-Info newsletter" above a comment is also worth thinking, the comment reminded: to prevent money wasted. Ouyang Zhongcan said that South Korea's production line built earlier than mainland China, mostly a-Si, and mainland China is low-temperature polysilicon, more competitive than South Korea, so the Korean manufacturers want other equipment to buy equipment, earn money The
At present the LCD process is determined, and OLED process is not determined. In addition, life is the weakness of OLED. A theoretical physicist's explanation: According to the quantum theory of uncertainty principle, energy level width and energy life of the product is constant, energy level inverse wavelength, so blue light life is shorter than red, OLED with a long time will change "red face" The Ouyang Zhongcan explained that the same energy under the red and blue, blue light is relatively weak, short life. Future mobile phone use more and more time, OLED mobile phone screen will not change "red face" it? So OLED may not be able to replace the LCD.
Ouyang Zhongcan said that some people will OLED TV with the best 4K LCD TV last year were compared, OLED TV in blackness, brightness, viewing angle clearly prevail. But there are also points out that "the choice of a TV depends entirely on the use of. In the picture quality and dazzling film experience, OLED TV in theory even better. This is because of its unprecedented perfect black level and picture reproduction. , The function comes from the cost.If the screen is only used to watch the general content and music, then 4K TV is the best for you.
