Abstract
A source driving circuit includes a gamma voltage generator, a common voltage generator and a driver. The gamma voltage generator receives gamma data from a timing controller through reduced swing differential signaling (RSDS) transmission interface to generate corresponding gamma voltages. The common voltage generator receives common voltage data from the timing controller to generate a corresponding common voltage. The driver receives image data from the timing controller through the RSDS transmission interface, the gamma voltages from the gamma voltage generator and the common voltage from the common voltage generator for modifying the image data using the gamma voltages and the common voltage and transmitting the modified image data to a panel of the liquid crystal display.
