LG Display OLED panels achieve perfect color and brightness certification

Buyers of high-end monitors and televisions now have independent confirmation that OLED screens can maintain precise color and brightness levels in typical room lighting. This certification addresses a common concern about display accuracy, ensuring that the vivid images advertised by manufacturers match what viewers actually see on their walls or desks. LG Display achieved this milestone by having its entire lineup of large-sized OLED panels tested and approved by Intertek. The "Perfect Color/Brightness Accuracy up to 500 lux" label verifies that these panels perform reliably under everyday viewing conditions rather than just in controlled dark rooms.

Intertek validates zero crosstalk and full accuracy in everyday lighting

The certification applies to LG Display's full range of large OLED panels intended for both computer monitors and television sets. These displays use self-emissive pixel technology, which allows each pixel to generate its own light without relying on a separate backlight unit. This fundamental architectural difference separates OLED panels from traditional LCD screens, which require a global or zone-based backlight to illuminate the image. The self-emissive nature of the OLED technology is central to the accuracy claims validated by the new certification.

Intertek, a global testing and certification organization, conducted the objective evaluation of picture quality accuracy across various viewing scenarios. The testing results confirmed that the LG OLED panels achieve 100% color accuracy and 100% brightness accuracy. The certification also verifies that the panels are free from color crosstalk, a defect where color information bleeds into adjacent pixels. This level of precision ensures that the displayed image remains consistent and true to the source material without distortion.

The testing process highlighted the limitations of LCD-based displays, which control light through backlight zones that can cause light leakage into adjacent areas. This leakage often leads to color distortion and reduced contrast in HDR content, particularly when bright objects appear against dark backgrounds. LG Display states that its OLED panels operate using pixel dimming technology, which fundamentally eliminates light leakage and interference. This technical advantage allows OLED screens to deliver accurate color and brightness even in environments with up to 500 lux of ambient light.

Hyeon-woo Lee, Head of the Large Display Business Unit at LG Display, stated that the OLED technology has been objectively proven to deliver the most accurate color and brightness. He emphasized that this accuracy holds true even in everyday viewing environments, not just in idealized studio conditions. The certification serves as a technical benchmark for consumers evaluating display quality. It provides a clear metric for distinguishing OLED performance from traditional LCD limitations in real-world usage.
