CORRELATED COLOR TEMPERATURE TRANSITION METHOD FOR RGBW ORGANIC LIGHT EMITTING DISPLAY DEVICE

摘要

PURPOSE: A color temperature converting method of an RGBW organic electroluminescent display device is provided to minimize the distortion of an optical compensation value by implementing the CCT(Correlated color temperature) conversion of a transition function. CONSTITUTION: A reference color temperature(CCT) of a display panel is set(S110). The optical compensation of a RGBW sub pixel is performed(S120). An optical compensation gain value of the reference color temperature is drawn. The section of a target color temperature is set. A transition function by section of the corresponding section of the target color temperature is generated(S130). The transition function by section is applied to the optical compensation gain value of the reference color temperature(S140). The optical compensation gain value of the reference color temperature is transitioned to the target color temperature inputted by a user. The optical compensation value of the color temperature of the RGBW sub pixel is generated(S150). The optical compensation value of the color temperature of the RGBW sub pixel is applied(S160).
