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.

Abstract: A driving method for rendering subpixels of each pixel of a display is provided. The display has a plurality of first pixels and a plurality of second pixels. Each second pixel has a first color subpixel and a second color subpixel, but lacks a third color subpixel. Each first pixel has a second color subpixel and a third color subpixel, but lacks a first color subpixel. The first color subpixel, second color subpixel and third color subpixel are used to represent gray levels of a first color, a second color and a third color respectively. Processes of rendering the subpixels of each pixel are performed based on positions, saturations and brightness of neighboring pixels, such that quality of image displayed on the display could be ensured even though each first pixel lacks the first color subpixel and each second pixel lacks the third color subpixel.
