  • Patent number: 5396262
    Abstract: A polysilicon gate bus structure used for activating a row of pixels in a matrix of pixels of an active matrix liquid crystal display is described. The polysilicon gate bus is formed with a plurality of buffers interspersed along its length. A plurality of field effect transistors, each associated with one pixel in a row of pixels, have their gate electrodes connected to the polysilicon gate bus with the buffers interspersed among the gate electrode connections so as to speed up a row scanning signal propagation time to each of the gate electrode connections.

  • Patent number: 5365355
    Abstract: A back plate structure for a reflective type active matrix liquid crystal display and methods for forming the same, is described. The structure includes an array of reflective electrodes for selectively altering the molecular alignment of liquid crystal material confined above each of the reflective electrodes and an array of light shields spatially offset with the array of reflective electrodes so that the light shields block light passing through portions of gaps formed between adjacent reflective electrodes. Each of the reflective electrodes also has a corresponding light shield which is electrically connected to that reflective electrode so that the liquid crystal material confined above portions of the gaps between adjacent reflective materials can also be altered by the electrically connected light shields.
