LG Display developed the world's first large organic light emitting diode (OLED) with applying convex lens technology that is twice as bright as conventional TVs. It took another leap from the last year’s OLED.EX panel, which applied heavy hydrogen technology and personalized algorithm.

The characteristics of the technology is forming a fine convex lens array layer inside the panel, instead of physically attaching the actual lens. The lens material went through a deposition process to be deposited on the OLED very thinly, and patterned to form a shape of convex lens. The lens array layer adjusts the angle of light that dissipates from inside the OLED panel, and amplifies it to increase brightness. The method adjusts the light towards the screen that reflected from the inside of the panel.
LG calls this technology 'Meta-lit Lens Array (MLA)’. OLED peak brightness increases by more than 20% compared to the previous OLEDs when applying MLA technology. The viewing angle will expand by the light scattering effect. The screen can be seen bright and clear even when viewing the TV from the side. The screen brightness reaches up to 2000 nits. This technology makes the OLED screens much brighter when considering that the maximum brightness of the current 1000 nits LG OLEDs.

LG Display first unveiled a 77-inch 8K OLED TV panel with MLA technology at the Society for Information Display’s (SID) Display Week  2022 held in San Jose, California on the 10th (local time) for three days.
LG Display’s 77-inch 8K OLED TV was the first in the world to apply both EX technology and MLA. The EX technology refers to the OLED.EX panel technology that was unveiled last year. LG Display plans to apply MLA technology to large premium OLED TV panel in the future. Hongjae Shin, a research fellow at LG Display, presented the research results on the principles and effects of MLA technology at the 'SID 2022' conference.
