A method of controlling a display device is disclosed including receiving a plurality of sub-pixel values for a target pixel among a plurality of pixels of an image frame, wherein the sub-pixel values of the target pixel comprise red, green, and blue sub-pixel values; calculating a pixel-based boosting ratio corresponding to the target pixel according to the sub-pixel values of the target pixel; and adjusting at least one of a plurality of backlight duties associated with the target pixel and the plurality of sub-pixel values of the target pixel according to the pixel-based boosting ratio.

Method and electronic device for controlling display device based on color perceived brightness

A method of color conversion from a red-green-blue (RGB) color space to a red-green-blue-white (RGBW) color space on an input image includes calculating RGB and white gains with respect to an image block of the input image, calculating RGB and white gain with respect to a pixel of the image block, wherein the white gain with respect to the pixel of the image block is adjusted based on the RGB gain with respect to the pixel of the image block, and performing the RGB to RGBW color conversion based on the RGB and white gain with respect to the pixel of the image block, which improves local color and detail performance of an output image corresponding to the input image.
