Abstract
A driving system of a liquid crystal display includes a pixel data line, a timing controller, a source driver and a gate driver. The pixel data line provides pixel data to the source driver directly. The timing controller is operative to receive a clock signal and a synchronization signal, so as to output a source control signal and a gate control signal. The source driver receives the clock signal, the source control signal and the pixel data, so as to output an image data signal. Upon receiving the gate control signal, the gate driver is operative to output an on/off signal.
Claims17
A driving circuit for a liquid crystal display, comprising:
- a timing controller for receiving a clock signal and a synchronization signal and outputting a source control signal and a gate control signal;
- a source driver electrically connected to the timing controller for receiving the source control signal;
- a gate driver electrically connected to the timing controller for receiving the gate control signal, so as to output an on/off signal;
- and
- a pixel data line directly connected to the source driver to provide a pixel data thereto,
- wherein the source driver is operative to output an image data signal by receiving the clock signal, the source control signal and the pixel data directly.
