ABSTRACT:
The present invention is directed to methods and devices to increase the brightness of images in display devices. A white signal component is generated according to an input color signal, comprising primary signal components Red, Green and Blue. The generated white signal component and the primary signal components will be manipulated by methods and devices disclosed in the invention to generate adjusted primary signal components. Then the white signal component and the adjusted primary signal components will form a display signal for displaying brightness controlled images. Compared with the input color signal, the brightness of the display signal is increased while the color saturation thereof is almost kept.
