Abstract:
1. A device for driving an LCD comprising: a timing control unit; a gate driving unit operatively connected to said timing control unit and operatively connectable to a power supply circuit, the gate driving unit having a shift register, a level register and an output circuit, wherein the shift register, level register and the output circuit operatively interconnected together; and a control signal transmission line operatively connected to the gate driving unit, the control signal transmission line for transmitting a data carry signal in which the data carry signal is used as an enable signal for each frame wherein the data carry signal is latched using the shift register, and the control signal transmission line for outputting an output control signal in which the output control signal is outputted after the data carry signal is latched, wherein a number of control signals required for driving the LCD is reduced whereby PCB design is simplified and signal interference phenomenon is reduced.
