Abstract: A method of displaying a high resolution multicolor image on a lower resolution display. The image comprises a plurality of image pixels containing at least first and second image subpixels having first and second colors. The image is displayed on a display having display pixels comprising at least first and second spatially offset display subpixels capable of displaying the first and second colors, respectively. In the method, the first display subpixel is displayed with an intensity which is a function of the intensities of at least two first image subpixels having positions extending over a first region having an area greater than the area of the first display subpixel. The first region is approximately centered on the position of the first display subpixel. A second display subpixel is displayed with an intensity which is a function of the intensities of at least two second image subpixels having positions extending over a second region having an area greater than the area of the second display subpixel. The second region is approximately centered on the position of the second display subpixel. By using a different centered region for each separate subpixel of a composite RGB display picture element in transforming a high resolution multicolor image to a lower resolution display, higher quality images are produced as compared to using a single region for each composite RGB display picture element.

Abstract: YO987-097 A METHOD FOR ELIMINATING CROSSTALK IN A THIN FILM TRANSISTOR/LIQUID CRYSTAL DISPLAY The elimination of crosstalk between data lines and pixel cells in a thin film transistor/liquid crystal display is accomplished by applying a data signal to a given data line for a time period less than the standard scan line period of the display, and applying a crosstalk compensation signal to the given data line for the remainder of the scan line period.

Abstract: of the Invention PROCESS FOR MAKING SELF-ALIGNING THIN FILM TRANSISTORS A process for making a self-aligned thin film transistor, said process comprising the steps of: (1) providing a gate which comprises a glass substrate, a transparent electrode on top thereof, and a metal electrode on top of said transparent electrode, (2) forming a stack by depositing over said gate a triple layer structure consisting of gate dielectric material, active material and a top passivating dielectric, (3) coating the top of said triple layer with a dual-tone photoresist, (4) exposing said photoresist from the top through a mask having transparent areas, opaque areas and areas transparent to selective wavelengths, using broad band UV light, (5) developing the photoresist by treatment with a solvent, (6) etching the stack with a liquid etchant through to the glass substrate, (7) exposing the photoresist from the bottom through the glass substrate using near UV light, (8) developing the photoresist with a solvent, and (9) etching off the top passivating layer of the stack.
