Abstract
A gate driver is provided. The gate driver generates a original signal by a signal generator, and then the original signal into a plurality of signal parts by a demultiplexer and the signal parts are transmitted into a corresponding gate channel in order to reduce the number of shift registers and level shifters of front-end circuit. Thus, the manufacturing cost of the gate driver and the space occupation of the chip can be effectively reduced.
Claims12
A gate driver, comprising:
- a signal generator, for generating at least one original signal having a plurality of gate driving periods during an actuating period;
- and
- a demultiplexer, coupled to the signal generator, for dividing the original signal into a plurality of signal parts and transmitting the signal parts to a corresponding gate channel during the gate driving periods, wherein the gate channel corresponds to a gate line of a load.
