LIQUID CRYSTAL DRIVING DEVICE AND DRIVING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a liquid crystal driving device which improves uniformity of a screen and does not have a gate printed circuit board and a driving method therefor. SOLUTION: The liquid crystal driving device which generates gate-on/off signals to drive a liquid crystal comprises; a sequence recognition means for recognizing the sequence of a pertinent gate driver IC from the pulse width of a vertical start signal inputted in synchronization with a vertical synchronous signal and generating the carry signal and the location signal of the pertinent gate driver IC; and a gate-off voltage generation means for receiving a first gate-off voltage and location data of the pertinent gate driver IC and outputting a second gate-off voltage which is generated by subtracting a voltage attenuation quantity corresponding to the location data of the gate driver IC from the first gate-off voltage.
