ABSTRACT:
An active matrix thin film transistor liquid crystal display having two thin film transistors for use in driving each of the liquid crystal pixels making up the matrix of the display. The first thin film transistor associated with each pixel is used in driving the pixel to capture data off of data lines in response to gate drive signals. The second thin film transistor associated with each pixel is used in compensating for the parasitic capacitances associated with the first thin film transistor and is driven by special compensating pulses.
