LG Display announced that its large sized OLED panels for TVs and monitors have received the industry’s first “100% dimming consistency” verification from UL Solutions. The certification confirms the performance of OLED pixel level dimming technology.
Dimming consistency measures how well a display maintains brightness as the reference test area on the screen becomes smaller. LG Display’s OLED panels maintained identical maximum and minimum brightness values even when the test area was reduced to 2/1000 of the panel, achieving 100% consistency. In comparison, LCD panels recorded dimming consistency between 83% and 43% as the area decreased.
OLED achieves this because each pixel emits its own light at around 0.1 mm². This enables stable brightness, accurate color boundaries and reduced light bleeding. LCD based RGB Mini LED panels rely on much larger backlight blocks, which can cause brightness variation and halo effects.
LG Display also highlighted its new OLED TV panel with Primary RGB Tandem 2.0 technology. It stacks red, green and blue light layers independently, reaching peak brightness up to 4,500 nits and reflectance as low as 0.3%.
