LG Display OLEDs Earn Verification
LG Display announced that its large-sized OLED panels for TVs and monitors have earned the industry's first "100% dimming consistency" verification. The recognition certifies the panels' ability to maintain consistent brightness and color accuracy even at low grayscale levels, a technology the company calls "perfect dimming."
- The verification was conducted by UL Solutions, a global independent safety science company, which lends third-party credibility to the "100% dimming consistency" claim. - The test for dimming consistency measures whether a display can maintain brightness and color as the size of a bright image on the screen shrinks. LG's OLEDs achieved a 100% rating, while LCD-based panels reportedly dropped to as low as 43% consistency in the same test. - This level of consistency is possible because OLED technology controls light at the individual pixel level, allowing for perfect black levels and avoiding the "halo" effect or light bleed common in backlit displays like Mini-LED. - The superior performance in dimming is a key factor in accurately displaying high-contrast HDR (High Dynamic Range) content, ensuring that small, bright highlights in a dark scene retain their intended intensity and color. - LG Display states this "perfect dimming" capability is crucial for the AI era, where displays will need to precisely and naturally render the rich visual information generated by artificial intelligence. - The technology is featured in LG Display's large-sized OLED panels for both televisions and monitors, and underpins their new OLED TV panel which uses a proprietary "Primary RGB Tandem 2.0" technology.
