Display circuit structure for liquid crystal display

摘要

A scan line is used to control two thin film transistors and a video data line is used to transmit video signal to pixel capacitors and maintenance capacitors. When the thin film transistors are selected by the selection signal, the video signal stored therein charges the pixel capacitors and maintenance capacitors. When the selection signal is removed, the charge in the pixel capacitors is preserved until the next repetition when that scan line is again selected by a selection signal and new voltages are stored therein. Thus a picture is displayed on the matrix display by the charges stored in the pixel capacitors.
