Abstract

The invention discloses a method for a display driving circuit and the display driving circuit. The method comprises the following steps: receiving display data through a display interface; detecting whether the display driving circuit enters a non-operation state, wherein the display driving circuit stops refreshing a display screen in the non-operation state; and setting an internal circuit of the display driving circuit in a power supply state in response to detecting that the display driving circuit enters the non-operation state, so as to save the power consumption of the internal circuit.
