Gate driver stage outputting multiple, partially overlapping gate-line signals to a liquid crystal display
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.
