(54) Method and apparatus for generating gate control signal of liquid crystal display


(57) A liquid crystal display is disclosed, which includes a panel having an array of pixels, a timing controller outputting image data and source control signals, a series of source drivers and a gate driver. One of the source drivers is selected to generate gate control signals by reference to an identification signal of the source control signals and transmitted to the gate driver. Thus, the gate driver along with a selected one of the source drivers can drive the panel pixels.
Each source driver comprises transcievers and can operate in one of two modes. In a first mode, control and image data are received by the driver. In the second mode control and image data are transmitted to a next source driver.
