The 'Color Perception Difference Evaluation Method' developed by LG Display for the first time in the industry was recently officially established as an international standard by the International Electrotechnical Commission (IEC). IEC is one of the world's three major standardization organizations recognized by the World Trade Organization, and major global manufacturers measure product performance according to IEC standards.
On the 31st, LG Display announced that the new image quality evaluation method it designed has been adopted as an international standard.
Color perception difference is a phenomenon in which the same color displayed by the display is perceived differently by each viewer, resulting in color distortion. It is mainly caused by the visual characteristics of the viewer. The difference may be greater depending on the display type.
For example, even if we look at the same white color, we see it differently, such as white mixed with blue or white mixed with yellow. The smaller the difference, the more accurately the general viewer can see the colors intended by the original author. It can also increase work efficiency in industries that require high color accuracy, such as the medical industry that requires image interpretation or the video production industry where multiple people work together on the same scene.
The establishment of this standard provides consumers with a standard for selecting displays that express consistent and accurate colors. LG Display's 'Color Perception Difference Evaluation Method' is a method of calculating and quantifying the difference between the colors precisely measured by a machine for seven standard colors under lighting similar to natural light and the colors seen by the human eye.
According to the new standard, LG Display's large OLED panel had a color perception difference of only about 10%, the lowest level in the industry. This means that color accuracy is high. Some high-definition displays overemphasize red, green, and blue (RGB) pixels, which can cause differences in color perception depending on the sensitivity of visual cells. LG Display's OLED panel alleviates this phenomenon by implementing a light spectrum close to natural light with white organic light emitting elements. You can.
LG Display CTO Sooyoung Yoon said, “We will continue to introduce products and technologies that can provide differentiated customer value with LG Display OLED, which has industry-leading high brightness, infinite contrast ratio, and accurate color expression.”
