Patent ID: 8847869

Claim:
A liquid crystal display device, comprising: a liquid crystal panel having a pixel array; a gate driver unit for generating a plurality of driving signals to drive the pixel array; a clock generator electrically coupled to the gate driver unit; and a temperature compensation unit electrically coupled to the gate driver unit and the clock generator, the temperature compensation unit adjusting an output of the clock generator for compensating the driving signals generated from the gate driver unit according to a temperature variance of one of a plurality of shift register units of the gate driver unit, the output of the clock generator being a pulse wave having a high level of a first voltage and a low level of a second voltage, the temperature compensation unit comprising: a temperature sensor for sensing the temperature variation of the one of the shift register units of the gate driver unit, and converting the temperature variation to a variation of a voltage; and a negative voltage adjusting unit electrically coupled to the temperature sensor for adjusting the second voltage from the clock generator according to the variation of the voltage.
