  • Publication number: 20160057396
    Abstract: The invention provides an image device with improved chrominance quality. The image device includes a plurality of RGBW pixels and a plurality of RGBY 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. In a RGBW pixel, the blue sub-pixel has an area about the same as that of the other sub-pixels in the same RGBW pixel. In a RGBY pixel, the blue sub-pixel has an area larger than that of the other sub-pixels in the same RGBY pixel. The RGBW pixels and RGBY pixels are mixed in the image device. Therefore, a white balance status can be achieved within one RGBY pixel, and thus the chrominance quality of the display can be improved.

  • Publication number: 20150235393
    Abstract: A data processing system that in order to process subpixel rendered RGB data such as Clear Type™ font data to be processed and put correctly on a non-RGB stripe image device such as a 2×2 matrix RGBW quad pixel image device, a matching 2×2 quad pixel image device is selected to cope with the corresponding input data triplet from the subpixel rendered RGB input data string. Since the blue dot carries the least luminance information in a white balance, Green/Blue/Red (GBR) triplet from the subpixel rendered input RGB data string is selected to match with a 2×2 matrix quadpixel image device where G and R dots of the 2×2 quad pixel have the maximum overlapping area with the corresponding G and R dots from the GBR stripe pixel data.

  • Publication number: 20150002562
    Abstract: A display formed with multiple pixel groups arranged in a matrix manner. Each of the pixel groups has multiple dots arranged in a predetermined identical matrix form, and has at least one first color dot, at least one second color dot and at least one third color dot. Each color dot has multiple sides adjacent to the other dots having a different color. Each color dot represents a luminance and a chrominance of corresponding full color pixel data by grouping with neighboring dots to form a plurality of overlapping full color dynamics pixel groups. The display has good spatial frequency in both X and Y axes, thus giving a higher visual perception of high resolution after performing weighted dot rendering methods, in which each dot in the display represents the luminance and chrominance of each corresponding RGB pixel by forming overlapping dynamic pixels with neighboring color dots.
