  • Patent number: 7588881
    Abstract: A thin film transistor liquid array substrate includes forming a plurality of amorphous silicon thin film transistors and storage capacities on a transparent substrate, wherein the amorphous silicon thin film transistors and the storage capacities are arranged in an array pattern. The storage capacitor has a top electrode and a bottom electrode, which are made of transparent conductive material to increase aperture ratio. A method of making the amorphous silicon thin film transistors and the storage capacities includes four photomask processes and a back exposure technique. Because the present invention only uses four photomask processes, the number of photomasks used in the process of the present invention is less than the conventional method, and the cost of fabrication is lower also.

  • Publication number: 20070159492
    Abstract: An image processing method is provided for generating multi-color data comprised of three primary-color sub-pixels and a brightness-enhancing sub-pixel, where a combination selected three at a time from these sub-pixels constituting a target pixel for the image processing method. First, a three-color pixel is converted into a four-color pixel, where the sub-pixels of the four-color pixel identical with those of the target pixel are represented by first numerical values, and the sub-pixel of the four-color pixel different to that of the target pixel is represented by a second numerical value. Then, the first numerical values are correlated with third numerical values discarded by neighboring pixels of the target pixel to determine the actual output of the target pixel.
