Abstract: A thin-film transistor (TFT) switch includes a gate, a drain, a source, a semiconductor layer, and a fourth electrode. The drain is connected to a first signal. The gate is connected to a control signal to control the switch on or off. The source outputs the first signal when the switch turns on. The fourth electrode and the gate are respectively located at two sides of the semiconductor layer. The fourth electrode is conductive and is selectively coupled to different voltage levels, thereby reducing leakage current in a channel to improve switch characteristic when the switch turns off.

Abstract: The present invention provides a liquid crystal display (LCD) panel including a top substrate, a bottom substrate, and a liquid crystal (LC) layer. The bottom substrate further includes an insulating layer between a bottom common electrode and a share sheet. A sub pixel is set on the insulating layer and next to the share sheet. The share sheet is electrically connected with A third thin film transistor (TFT) through a via and extends forward an end of the adjacent sub pixel. A share capacitance is set between the share sheet and the bottom common electrode of the adjacent sub pixel. A drain of the third TFT is coupled to the share capacitance so the two adjacent pixel units display solid color picture when short occurs between the adjacent sub pixel and the share capacitance. The detection is easy and effective so the yield is increased.
