    Abstract: A display driving circuit adapted to drive a display panel to display an image is provided. The display driving circuit includes a source driver circuit and a timing controller circuit. The source driver circuit is configured to sense whether noise occurs and output a lock signal. The lock signal indicates whether the noise occurs. The timing controller circuit is coupled to the source driver circuit, and configured to output image data to the source driver circuit and receive the lock signal from the source driver circuit. The timing controller circuit adjusts a data depth of the image data or a frame rate of the display panel when the lock signal indicates the noise occurs.

    Abstract: A method for reducing operating temperature of a source driving circuit and a display system are provided. The method for reducing operating temperature of a source driving circuit includes enabling an over-temperature protection operation by the source driving circuit; and transmitting, by the source driving circuit, a first signal to a timing controller in response to detecting a temperature increasing to be higher than the first threshold temperature, wherein the timing controller is configured to operate a temperature reducing operation in response to receiving the first signal.

    Abstract: A display driver and a polarity inversion method thereof are provided. The display driver includes multiple channel pairs and a polarity inversion control circuit. The channel pairs are suitable for driving a display panel. Each of the channel pairs includes a positive polarity channel, a negative polarity channel, and a switching circuit. The polarity inversion control circuit controls the switching circuits so that the position where the polarity of a first data line of the display panel is inverted in a first frame period is different from the position where the polarity of the first data line is inverted in a second frame period. The display driver can prevent polarity inversion from occurring at a fixed position as much as possible.

    Abstract: A control method, suitable for a display panel including M scan lines and a plurality of source lines, include following operations. M is a positive integer. M gate signals are generated sequentially in M time periods during a first display frame to the M scan lines of the display panel. A level of a data signal to one of the source lines is updated in the M time periods during the first display frame. N gate signals are generated in N time periods selected from the M time periods during a second display frame to N scan lines selected from the M scan lines. (M-N) gate signals are suspended during the second display frame. The level of the data signal is updated in the N time periods and is not updated in the (M-N) time periods during the second display frame. N is a positive integer smaller than M.
