Abstract
A gate driver includes a plurality of stage groups, a gate driving circuit, and an output controller. The gate driving circuit supplies the plurality of stage groups with a plurality of clock pulses. The plurality of stage groups supply the input clock pulses to associated gate lines of a liquid crystal panel. The output controller generates a plurality of control voltage signals that control which of the plurality of stage groups generate an output signal.
Claims27
A gate driver comprising:
- a plurality of stages for supplying input clock pulses to associated gate lines of a liquid crystal panel, respectively;
- a gate-driving integrated circuit for dividing the stages into m stage groups each including n stages, and supplying n phase-different clock pulses to each of the stage groups;
- and
- an output controller that controls which of the plurality of stage groups generate an output signal,
- wherein m is a natural number greater than or equal to 2, and wherein n is a natural number greater than or equal to 2.

A gate driver comprising:
- a plurality of stages each supplying a currently-input clock pulse to an associated one of gate lines of a liquid crystal panel in accordance with a clock pulse supplied from the stage previous to the stage associated with the gate line, while being disabled in accordance with a clock pulse supplied from the stage next to the stage associated with the gate line;
- and
- a gate-driving integrated circuit for dividing the stages into m stage groups each including n stages, and supplying n phase-different clock pulses to each of the stage groups,
- wherein m is a natural number greater than or equal to 2, and
- wherein n is a natural number greater than or equal to 2.

A gate driver comprising:
- a plurality of stages each supplying a currently-input clock pulse to an associated one of gate lines of a liquid crystal panel in accordance with a clock pulse supplied from the stage previous to the stage associated with the gate line, while being disabled in response to a clock pulse having a phase identical to a phase of a clock pulse supplied to an input terminal of the stage next to the stage associated with the gate line;
- and
- a gate-driving integrated circuit for dividing the stages into m stage groups each including n stages, and supplying n phase-different clock pulses to each of the stage groups, wherein m is a natural number greater than or equal to 2, and
- wherein n is a natural number greater than or equal to 2.
