Abstract
The invention relates to a display and an image data processing system. According to the arrangement of the display, two color dots having lower light intensity than the other two color dots in a white balance status are disposed on diagonal positions of the pixel group. Therefore, the display of the invention can improve the color balance in the pixel group to avoid visible dark vertical line. The image data processing system of the invention utilizes the weighted dot rendering device for pre-compressing data. We can expect that the video compressed data size or the video transmission speed is reduced accordingly to a ratio of ⅓ (¼ in the case of RGBW of 2×2 matrix arrangement because white (W) can be regenerated from the corresponding R, G, B), thus storage memory and transmission bandwidth can be reduced considerably without degrading the visual perception of the video quality on the proprietary VP display.
