LG Display's 'Color Perception Difference Evaluation Method' Adopted as International Standard

Development of a New Image Quality Assessment Method

LG Display's newly devised image quality evaluation method has been adopted as an international standard.

LG Display announced on the 31st that its industry-first developed 'Color Perception Difference Evaluation Method' was recently officially established as an international standard by the International Electrotechnical Commission (IEC).

The IEC is one of the world's top three standardization organizations recognized by the World Trade Organization, and major global manufacturers measure product performance according to IEC standards.

Color perception difference refers to the phenomenon where the same color displayed by a display is perceived differently by different viewers, causing color distortion. This mainly occurs due to the visual characteristics of the viewers, and the difference can be greater depending on the type of display. For example, even when looking at the same white, some may see white mixed with blue, while others see white mixed with yellow.

The smaller this difference, the more accurately general viewers can see the colors intended by the original creator, and it can also improve work efficiency in industries requiring high color accuracy, such as the medical field where video interpretation is necessary, or the video production industry where multiple people collaborate on the same scene.

An LG Display official explained, "Previously, color accuracy was evaluated based on how good a display's color reproduction was, without reflecting the color perception differences occurring among viewers," adding, "The significance of this standard establishment lies in providing a criterion to select displays that express consistent and accurate colors to consumers."

LG Display's color perception difference evaluation method quantifies and calculates the difference between colors precisely measured by machines under lighting similar to natural light for seven standard colors and the colors perceived by the human eye.

According to the new standard, LG Display's large OLED panels showed a color perception difference of about 10%, the lowest level in the industry, indicating high color accuracy. Some high-definition displays may cause color perception differences due to excessive emphasis on red, green, and blue (RGB) pixels, which can vary according to cone cell sensitivity. However, LG Display's OLED panels implement the spectrum of light from white organic light-emitting elements close to natural light, mitigating this phenomenon.
