LG OLED earns industry-first ‘perfect black’ verification

Covering all its OLED panel models ranging from 42 to 97 inches, LG Display has received ‘perfect black’ verification from independent safety science company UL Solutions.

Most displays are affected by external light when expressing colours, including black. Consequently, the ability to express accurate black levels regardless of external illumination results in higher colour expression and sharper images.

UL Solutions evaluated the black levels of various displays in a brightly illuminated environment of 500 lux, similar to a living room in broad daylight. Through this assessment process, LG Display’s OLED panels were shown to deliver black levels of 0.15 nit.

By achieving a black level that is around 40% lower than standard ‘perfect black’ criteria of 0.24 nit, LG Display’s OLED was able to become the first existing panel to receive the ‘perfect black’ verification.

Thanks to self-emissive pixels that can be controlled individually, LG Display’s OLED panels minimise light leakage and external light reflections by turning off pixels to achieve the perfect black and infinite contrast, delivering a true image without distortion or exaggeration.

LG Display’s OLED panels have previously been recognised for their ability to accurately express true images in terms of brightness, chroma, and colour chromaticity, having received the ‘100% Colour Fidelity’ verification from Intertek, a global product testing and certification company, prior to the recent ‘Perfect Black’ verification.

“Through UL Solutions’ objective and science-based assessment, LG Display’s OLED has been proven to be the first panel to deliver perfect black levels,” said Jin Min-kyu, head of the life display promotion division at LG Display.

“Utilising the recent verification from UL Solutions, we will continue to actively promote the excellent image quality of OLED.”
