Abstract: A display device includes a processor circuit, a driver circuit, and a display panel. The driver circuit is coupled to the processor circuit to detect whether there is abnormal transmission between the processor circuit and the driver circuit. The display panel is coupled to the driver circuit. The display panel includes a display array and a shift register circuit. The display array is to display an image. The shift register circuit is coupled to the display array. When there is the abnormal transmission in a first display period of a first frame, the driver circuit outputs a control signal having a disable level in the first display period to the shift register circuit to control the shift register circuit not to operate in order to stop updating the image.

Abstract: The present invention discloses a driving method for a source driver, for driving a source line of a display panel. The driving method includes the steps of: driving the source line with a first voltage or a second voltage smaller than the first voltage in a first driving cycle; driving the source line with the first voltage in a second driving cycle next to the first driving cycle when the source line is driven with the first voltage in the first driving cycle; and driving the source line with an overdrive voltage in the second driving cycle when the source line is driven with the second voltage in the first driving cycle. The first voltage is a normal high voltage of the display panel, and the overdrive voltage is greater than the normal high voltage.
