Abstract:
1. A liquid crystal display (LCD) device comprising: a liquid crystal panel having a plurality of pixel regions defined by a plurality of gate lines and a plurality of data lines, each pixel region being associated with a thin film transistor; a first gate driving unit and a second gate driving unit connected with the liquid crystal panel, the first and second gate driving units are made of an amorphous semiconductor, and the first and second gate driving units operable to send scan signals to odd numbered gate lines and even numbered gate lines respectively, each scan signal is extended as wide as a width of a signal lowered due to a low field effect mobility of the amorphous semiconductor, thereby having a pulse width greater than a turn-on time of a thin film transistor formed at the pixel region, wherein each of the first gate driving unit and the second gate driving unit include a clock signal generating unit which generates a plurality of clock signals C wherein the scan signal has a turn off period, and a turn on period including a first period for partially turning on a thin film transistor and a second period for fully turning on a thin film transistor, where the first period is shorter than the second period, and wherein the turn on period is extended by a width corresponding to the first period.
