LG Display announced that the International Electrotechnical Commission (IEC) has adopted its “color perception difference measurement method” as an international standard. According to the new standard, LG Display’s large-sized OLED panels have high color accuracy, with a color perception difference of only about 10%, the lowest in the industry.
LG Display explains that in this context, differences in color perception refer to a phenomenon in which different viewers perceive the same color differently when it is shown on a display, resulting in color distortion. It is mainly caused by viewers’ visual characteristics, but the difference can be greater depending on the type of display. For example, the same white color can be perceived by different viewers to have either a blue or yellow tone.
Until now, the general opinion has been that the better a display’s color reproduction, the higher its color accuracy. But this does not reflect differences in viewers’ color perception. The significance of the new standard is that it provides consumers with a way to select displays that express consistent and accurate colors.
LG Display's measurement method quantifies and calculates the difference between the machine-measured color of seven standard colors and that seen by the human eye under conditions similar to natural light.
While some high-definition displays potentially cause differences in color perception by overemphasizing
red, green, and blue (RGB) pixels, depending on the eye sensitivity of viewers, LG Display’s OLED panels alleviate this phenomenon by using with white organic light emitting elements to create a light spectrum that is close to natural light.
