Abstract: A liquid crystal display includes a base plate having a plurality of pixels on a surface thereof with the pixels arranged in an array of spaced rows and columns. Each of the pixels includes a substantially rectangular region of polycrystalline silicon. A separate select line of polycrystalline silicon extends over and across the polycrystalline silicon regions of each row of pixels adjacent one side of the polycrystalline silicon region. The select lines has two extensions extending over and along two opposite sides of each polycrystalline silicon region. A layer of a dielectric material extends between the polycrystalline silicon regions and the first lines and the extensions of the first lines. Each of the first lines and its extensions forms a capacitor with the respective polycrystalline silicon region of each pixel. Data lines extend along the rows of the pixels and are electrically connected to each polycrystalline silicon region in its respective column of pixels.

Abstract: A Self Scanned Amorphous Silicon Integrated Display (SASID) uses one or more operational amplifiers in a differential amplifier configuration, to apply the ramp signal to the column drivers. The operational amplifiers are configured to receive the ramp signal at non-inverting input terminals and to apply the ramp signal to the data bus at respectively different locations. The operational amplifiers are also coupled to receive respective feedback signals at inverting input terminals. The feedback signals are taken from points on the bus that are distant from the point at which the amplifiers apply the ramp data signal to the bus. The display device includes a column driver having an initialization sequence in the vertical blanking interval. The signal used to render the column driver TFT conductive is determined in the vertical blanking interval and maintained on a capacitor in the column driver for the duration of the vertical field.
