Abstract
A liquid crystal display device includes a timing controller generating a voltage compensation control pulse and a gate control signal, a voltage compensation signal generator generating a voltage compensation signal, the voltage level of which is gradually reduced during one frame period, in response to the voltage compensation control pulse, a power unit outputting a gate-on voltage to a plurality of gate lines by gradually increasing the level of the gate-on voltage in response to the voltage compensation signal, and a gate driver sequentially supplying the gate-on voltage to the plurality of gate lines in response to the gate control signal.

A liquid crystal display (LCD) device comprising:
- a timing controller generating a voltage compensation control pulse and a gate control signal;
- a voltage compensation signal generator generating a voltage compensation signal, of which voltage level is gradually changed during one frame period, in response to the voltage compensation control pulse;
- a power unit outputting a gate-on voltage to a plurality of gate lines by gradually changing the level of the gate-on voltage in response to the voltage compensation signal;
- and
- a gate driver having a plurality of stages, the gate driver sequentially supplying the gate-on voltage to the plurality of gate lines in response to the gate control signal.
A method of driving an LCD device, comprising:
- generating, at a timing controller, a voltage compensation control pulse and a gate control signal;
- generating, at a voltage compensation signal generator, a voltage compensation signal, a voltage level of the voltage compensation signal being gradually reduced during one frame period, in response to the voltage compensation control pulse;
- outputting, at a power unit, a gate-on voltage to a plurality of gate lines by gradually increasing the level of the gate-on voltage in response to the voltage compensation signal;
- and
- supplying, sequentially, at a gate driver, the gate-on voltage to the plurality of gate lines in response to the gate control signal.
