HUE-ADAPTIVE SATURATION INCREASE FOR OLED DISPLAY POWER REDUCTION

Abstract: a processing system adjusts a saturation component of a hue-saturation-value (hsv) color space pixel input for an organic light emitting diode (oled) display panel as a function of the hue component. the processing system converts components of a pixel input from a non-hsv color space to hsv components of the pixel input in hsv color space and modifies the saturation component of the pixel input in hsv color space based on the hue component of the pixel input to generate modified hsv components of the pixel input. the processing system then converts the modified hsv components of the pixel input back into the original color space to produce modified components of the pixel input in the original color space and provides the modified components of the pixel input for receipt by the oled display, allowing the pixel to be driven at a lower pixel value while maintaining perceptual quality.
