More Information
Summary:The present invention provides an organic light emitting display comprising: a cognitive profit control unit which controls the profit of RGB signal data for a color to be controlled based on the color difference (ΔEab), which reflects the cognitive characteristic of human; a data control unit which converts the RGB data signal into RGBW data signal and compensates the RGBW data signal; and a display panel which displays an image based on the RGBW data signal. 본 발명은 사람의 인지 특성을 반영하는 색차(△Eab)를 기준으로 색이 제어되도록 RGB 데이터신호의 이득을 조절하는 인지적 이득조절부; RGB 데이터신호를 RGBW 데이터신호로 변환함과 더불어 RGBW 데이터신호를 보상하는 데이터 조절부; 및 RGBW 데이터신호를 기반으로 영상을 표시하는 표시 패널을 포함하는 유기전계발광표시장치를 제공한다.
