RGB Tandem OLED certified "perfect" for bright living rooms

Are OLED TVs still too dim for bright living rooms? According to LG Display and certification center UL, that is no longer the case.

OLED TVs are still not as bright as the brightest miniLED LCDs, but both WOLED and QD-OLED have made notable progress in recent years.

Specifically, full-screen brightness – when the entire display is illuminated white – has increased from around 150 nits on early OLED TVs to approximately 350-400 nits on 2025 models such as LG G5 (review) and Samsung S95F (review) – roughly 2.5 times brighter. Peak brightness in small areas of the pictures has also jumped from around 600 nits to over 2000 nits in calibrated mode, or up to 3500 nits momentarily in vivid mode.


Bright enough?
While 400 nits in full-screen is still below the 600–800 nits achieved by some of the latest, brightest miniLED LCD TVs from brands like Hisense and TCL, the more relevant question is if it is enough.

 4th-gen OLED has more emissive layers
According to LG Display, the maker of all WOLED panels, it is, backed by certification from global safety science company UL Solutions for the 4th-gen RGB Tandem OLED panel, which also features low-reflection coating.

- "LG Display announced today that its fourth-generation OLED panels have been verified by UL Solutions, a global leader in applied safety science, for Perfect Reproduction technology under lighting conditions of up to 500 lux, which is the brightness of a living room in broad daylight," said LG Display and continued:

- "To put it another way, these panels perfectly reproduce content at a level of visual quality typically found only in darkened movie theaters, even when they are placed in the brightest living room."


Brightness and perceived brightness
UL Solutions explained that this industry-first certification applies to both color and brightness reproduction in bright rooms, with over 95% of the original 4K test images being accurately reproduced on RGB Tandem OLED.

This follows UL Solutions' previous verification of claims from Samsung Display, the maker of QD-OLED panels, that a 300-nit OLED can match a 500-nit LCD in perceived brightness.
