Abstract
The invention provides an image device with improved chrominance quality. The image device includes a plurality of RGBW pixels, a plurality of RGBY pixels, and a plurality of RBGB pixels. Each RGBW pixel includes a red sub-pixel, a green sub-pixel, a blue sub-pixel and a white sub-pixel. Each RGBY pixel includes a red sub-pixel, a green sub-pixel, a blue sub-pixel and a yellow sub-pixel. Each RBGB pixel includes a red sub-pixel, a green sub-pixel, and two blue sub-pixels. The RGBW pixels, RGBY pixels, and RBGB pixels are mixed in the image device. The image device of the present invention can solve the problem of dark yellow in the conventional RGBW display while achieving a white balance status. As a result the chrominance quality is improved.
