Abstract: A driving circuit includes several first electrostatic current limiting resistors and several digital to analog converter (DAC) units. First ends of these first electrostatic current limiting resistors common coupled to a global path to receive a reference voltage. These DAC units respectively coupled to second ends of the first electrostatic current limiting resistors one-on-one to receive the reference voltage through the first electrostatic current limiting resistors.

Abstract: A display driving apparatus configured to drive a display panel is provided. The display driving apparatus includes a plurality of source drivers. The source drivers are configured to output a video image data to drive the display panel. Each of the source drivers includes a plurality of driving channels. Each of the source drivers randomly turns on at least one of the included driving channels via a control signal, so as to allow the driving channels outputting the video image data. In each of the source drivers, at least a part of the driving channels are randomly turned on to output the video image data. Furthermore, a method for driving the display panel of the foregoing display driving apparatus is also provided.
