LG Display OLED panels receive ‘Perfect Black’ verification

LG Display has announced that its OLED panels have received ‘Perfect Black’ verification, noting that they are currently the only existing TV and monitor panels to achieve perfect black levels in any environment.

This ‘Perfect Black’ verification covers all OLED panel models, ranging from 42- to 97-inches, from US-based UL Solutions, a recognised test and measurement laboratory.

The observation is actually reflective of a panel’s ability to display a full gamut of colour. Most displays are affected by external light when expressing colours, including black. More accurate black levels, regardless of external illumination, results in higher colour expression and sharper images, says the company.

UL Solutions evaluated black levels of various displays in a brightly illuminated environment of 500 lux. This is similar to the brightness of a living room in daytime. LG Display’s OLED panels were shown to deliver black levels of 0.15 nit. By achieving a black level that is around 40 per cent 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.

OLED’s self-emissive pixels can be controlled individually, which minimises light leakage and external light reflection.

LG Display’s OLED panels have previously received ‘100% Color Fidelity’ verification from Intertek, another global product testing and certification company, reflecting their accuracy when it comes to brightness, chroma, and colour chromaticity.
