Abstract: A method of handling operation of a source driver of a display system used in a timing controller of a display system, which is coupled to the source driver via a data bus for delivering a plurality of line data, includes determining whether a first line data among the plurality of line data is identical to a second line data among the plurality of line data previous to the first line data; and transmitting a sleep command to the source driver when the first line data is determined to be identical to the second line data, wherein the sleep command instructs the source driver to enter a sleep mode; wherein the source driver stops receiving the plurality of line data from the timing controller when the source driver is in the sleep mode.

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.
