The invention discloses a control circuit and method thereof, which enable a display device to have low power consumption. The display device is able to switch between a normal mode and a standby mode, and reduce the power consumption of the display device under the standby mode. A synchro signal detection circuit, an infrared receiver, and a power switch are used to determine when to output a triggering signal. If an MCU inputs a triggering signal, a switch circuit will provide electricity for a peripheral circuit, then the display device switches to the normal mode; otherwise, the switch circuit will stop providing electricity for the peripheral circuit, and the display device switches to the standby mode.
