LG Display may apply micro lenses to OLED TV panels to further boost brightness by 20% to around 1200 nits. Production may start as early as this year, according to a report by The Elec.
By applying micro lenses to the existing OLED TV panel the light path can be optimized for efficiency, meaning that brightness is increased while overall power consumption is reduced.
- "LG Display is known to expect a 20% improvement in OLED luminance by applying a micro lens. Under the premise that the product lifespan is the same, if the OLED luminance increases, power consumption can be saved at the same luminance," the report said (translated).
This could increase peak brightness to 1200 nits. However, it would still be lower than Samsung Display's QD-OLED TV panel which maxes out at around 1500 nits.

- "The maximum luminance of LG Display's existing large OLED was 800 nits. The maximum luminance of OLED.EX is estimated to be 1000 nits, which is 30% higher than this. By adding a micro lens, the maximum luminance can be raised to 1200 nits."
Micro lenses may boost brightness an addition 20% compared to OLED EX
As early as this yearThe report cautions that LG Display is still reviewing the technology. If it decides to press forward, the "micro lenses are likely to be applied as early as this year" to mass-production units at one of LG Display's two current OLED TV factories (Paju, Korea and Guangzhou, China).
If mass production of panels starts in late 2022, the new technology may be introduced in LG's 2023 OLED TVs.
Micro lenses are already used in some LED LCD panels as well as mobile OLED panels including the one in Samsung's Galaxy S21 Ultra.
