Abstract
A gate driving circuit and a driving method thereof are provided. The gate driving circuit includes a control signal generator and at least one gate channel set, each of the at least one gate channel set includes a plurality of gate channels, and the plurality of gate channels share a level shifter. The driving method includes generating a plurality of first control signals and a plurality of second control signals according to a gate driver start pulse, and determining that one of the gate channels uses the level shifter during a time period according to the plurality of first control signals and the plurality of second control signals. Therefore, the number of the level shifters can be decreased.
Claims19
A gate driving circuit, comprising:
- a control signal generator, receiving a gate driver start pulse to generate a plurality of first control signals and a plurality of second control signals;
- and
- at least one first gate channel set, coupled to the control signal generator, wherein each of the at least one first gate channel set comprises a plurality of first gate channels, and the first gate channels are controlled by the first control signals and the second control signals to share a first level shifter, and generate a plurality of gate driving signals.
A driving method of a gate driving circuit, comprising:
- generating a plurality of first control signals and a plurality of second control signals according to a gate driver start pulse;
- and
- determining a plurality of first gate channels of a first gate channel set to share a first level shifter in time-division according to the first control signals and the second control signals, so as to generate a plurality of gate driving signals.
