Abstract
The present invention modifies LCD panel display modes with a simple circuit configuration. When a driving frequency is supplied that does not drive all the configured pixels, the present invention drives all the pixels according to a multisync mode. The present invention comprises a LCD panel including a plurality of gate lines, a plurality of data lines, and a plurality of TFTs each having a gate electrode connected to the gate line and having a source electrode connected to the data line; a data driver receiving four driving clock signals and performing a multisync function on the driving frequency; a gate driver receiving four shift clock signals and performing multisync function on the driving frequency; and a timing controller outputting four driving clock signals and shift clocks and changing and outputting the status of the four driving clock signal and the shift clocks according to the normal mode or multisync mode.
