Patent ID: 8018421

Claim:
A gate driver, comprising: a first driving circuit, comprising: a first shift register for outputting a first gate pulse according to a first voltage amplifying signal; a first logic circuit for outputting a first control signal according to a starting signal and the first gate pulse; and a first switch for controlling enablement of the first shift register by controlling whether an operation voltage is input to the first shift register according to the first control signal; and a first charge pump, coupled to the first shift register, for outputting the first voltage amplifying signal according to the starting signal; and a second driving circuit, coupled to the first driving circuit, the second driving circuit comprising: a second shift register for outputting a second gate pulse according to a second voltage amplifying signal; a second logic circuit for outputting a second control signal according to the first gate pulse and the second gate pulse; and a second switch for controlling enablement of the second shift register by controlling whether the operation voltage is input to the second shift register according to the second control signal; and a second charge pump, coupled to the second shift register, for outputting the second voltage amplifying signal according to the first gate pulse.
