LG Display's OLED panels earn world's first perfect color and brightness accuracy certification

LG Display announced Sunday that it has become the first company in the world to receive "Perfect Color/Brightness Accuracy up to 500lux" certification from global testing firm Intertek, covering its entire lineup of large OLED panels.

The certification confirms that LG Display's OLED panels faithfully reproduce the colors and brightness levels intended by content creators, regardless of viewing conditions or content type.

Until now, display performance has typically been measured against simple specifications such as color gamut and luminance, leaving no objective standard for verifying how accurately a panel reproduces color and brightness.

To assess whether a display accurately renders a creator's intended color and brightness, Intertek used a range of test patterns to measure and quantify color and brightness variations at specific points on the screen.

LG Display's OLED panels achieved 100% color accuracy, 100% brightness accuracy and a color crosstalk-free rating, demonstrating strong performance across all three metrics. Color crosstalk-free means each pixel reproduces its own color without any interference from surrounding areas.

By contrast, LCD panels tested using the same method fell short of 100% in both color and brightness accuracy.

LCD displays rely on backlight blocks far larger than individual pixels. In high-dynamic-range content — such as stars in a night sky or fireworks — where certain areas need to shine brightly, those displays were found to produce lower-than-intended brightness. Some premium LCD TVs using RGB LEDs also showed color distortion in on-screen objects depending on the background color of the image.

These differences stem from how each display technology emits light. LCD technology controls its backlight source by zone, a structural limitation that allows light to leak into adjacent zones. Even some premium LCD products suffered from color crosstalk, where surrounding colors bleed into and distort neighboring areas.

LG Display's OLED panels are driven by pixel dimming technology, in which millions of pixels independently emit their own light, eliminating light bleed and color interference at the source.

This allows the panels to reproduce a content creator's intended colors and brightness exactly as designed, across all conditions — whether the image is bright or dark, large or small in detail.

With the certification now quantifying OLED's advantages, LG Display said it plans to press its lead in the global display picture-quality competition.

"We have objectively proven that OLED accurately reproduces the color and brightness values that consumers need, exactly as the content creator intended," said Lee Hyun-woo, head of LG Display's large display business division. "We will continue to strengthen our market leadership by communicating the premium picture-quality value that only OLED can deliver to customers around the world."
