DRIVING CIRCUIT AND OPERATING METHOD THEREOF

A driving circuit includes a data comparator, a data processor and a driver. The data comparator determines whether a second row of image data is the same with a previous first row of image data. If YES, the data comparator outputs a disable signal, then the data processor stops operating according to the disable signal and outputs an indicating signal, and the driver outputs a previous first row of output image data to a panel according to the indicating signal; if NO, the data comparator outputs the second row of image data to replace the previous first row of image data, then the data processor processes the second row of image data to generate a second row of output image data, and the driver outputs the second row of output image data to the panel to replace the previous first row of output image data.
