摘要:
A gate driver for driving a TFT-LCD panel includes a number of gate-driver circuits arranged in groups and stages. Each gate-driver circuit has a main driver and an output section. The main driver is used to provide a charging signal to the output section which has two or more output circuits. Each of the output circuits is configured to provide a gate-line signal in response to the charging signal and a clock signal. The gate-driver circuit uses fewer switching elements, such as thin-film transistors, than the conventional circuit. When the gate driver is integrated in a TFT-LCD display panel and disposed within the periphery area around the display area, it is desirable to reduce or minimize the number of switching elements in the gate driver so that the periphery area can be reduced.

A tri-gate pixel structure includes three sub-pixel regions, three gate lines, a data line, three thin film transistors (TFTs), three pixel electrodes, and a common line. The gate lines are disposed along a first direction, and the data line is disposed along a second direction. The TFTs are disposed in the sub-pixel regions respectively, wherein each TFT has a gate electrode electrically connected to a corresponding gate line, a source electrode electrically connected to the data line, and a drain electrode. The three pixel electrodes are disposed in the three sub-pixel regions respectively, and each pixel electrode is electrically connected to the drain electrode of one TFT respectively. The common line crosses the gate lines and partially overlaps the three gate lines, and the common line and the three pixel electrodes are partially overlapped to respectively form three storage capacitors.
