Method for reducing operating temperature of source driving circuit and display system

A method for reducing operating temperature of a source driving circuit, the method comprising:

• enabling a pattern detection operation;
• and
• operating a temperature reducing operation in response to detecting a preconfigured pattern in a frame to be displayed, wherein the step of operating the temperature reducing operation comprises:
• transmitting, by a timing controller, a first signal to the source driving circuit in response to detecting the preconfigured pattern;
• controlling, by the source driving circuit, a plurality of data output nodes to stay in a first state in response to receiving the first signal, wherein the first state is a high impedance state or data voltages of a currently displayed frame;
• and
• transmitting, by the timing controller, the first signal to the source driving circuit after a preconfigured period from detecting the preconfigured pattern, such that the source driving circuit returns to a normal display state from an inactive state in response to receiving the first signal.
