During a conference in Korea, LG Display's OLED technical strategy team leader Lim Joo-son said that the company's WRGB technology does not place any limits to the size of the OLED TVs they can make, and once the M2 goes into operation, the company will be able to produce 110" TVs.
LG also managed to increase the pixel density, and can now produce 8K (7680x4320) panels - but they admit that the smaller aperture in such panels limits the lifetime and they urgently need to develop longer lasting OLED materials.
Finally, Loo-son said that LG Display decided to apply out coupling technology (used in OLED Lighting panels) to maximize the luminance efficiency.
