  • Patent number: 10950185
    Abstract: An organic light-emitting display (OLED) device includes an image display member, an aging display member, a degradation compensation control member for compensating for degradation of original image data of display pixels of the image display member. Aging pixels of the aging display member are degraded by reflecting image driving data of the display pixels, and the degradation of the original image data is compensated depending on degradation confirmation values of standard cumulative stress indexes corresponding to cumulative stress of the display pixels. The degree of degradation of the pixels may be accurately reflected while having a high aperture ratio, so that effective degradation compensation may be performed.
