Polysilicon gate bus with interspersed buffers for driving a row of pixels in an active matrix liquid crystal display

摘要

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.
