  • Image processing method, image processing circuit, and organic light emitting diode display device using the same
    Patent number: 10157568
    Abstract: Embodiments relate to reducing a ghost image effect caused by fixed images. In a region of the image with an opaque fixed image, a use rate (or intensity) of a color component with a lower luminous efficacy is decreased while a use rate (or intensity) of a color component with a higher luminous efficacy is increased to maintain the luminance. By reducing an excessive use of sub-pixels corresponding to a color component of the lower luminous efficacy, the deterioration of these sub-pixels can be reduced despite presenting a fixed image on the same region of the display.
