Abstract
A method for controlling a display is provided. An RGB video signal is transformed into an RGBW video signal based on a human factor. The display has a plurality of pixels configured to display images according to the RGBW video signal, where each of the pixels has a red subpixel, a green subpixel, a blue subpixel and a white subpixel. According to the method, when brightness of a backlight module of the display is reduced to decrease energy consumption of the display, quality of the images of the display observed by users is still maintained within an acceptable range.
