1. A touch display device, comprising a touch display panel, a touch display control driver circuit, a touch integrated circuit, a power management chip, and a touch operation processing circuit, the touch display device further comprising a power supply module; the power supply module comprising a first power supply terminal, a second power supply terminal, and a power supply control circuit;
wherein the power management chip provides the touch operation processing circuit, the touch display control driver circuit and the touch integrated circuit with an operating voltage;
a control terminal of the power supply control circuit is electrically connected to a control signal output terminal of the touch operation processing circuit;
the touch operation processing circuit is configured for providing a first control signal to the control signal output terminal when the touch display device is in a sleep state, to enable the power supply control circuit to supply power to the power management chip via the second power supply terminal under control of the first control signal; and the touch operation processing circuit is further configured for providing a second control signal to the control signal output terminal when the touch display device is in the sleep state and the touch display panel is touched, to enable the power supply control circuit to supply power to the power management chip via the first power supply terminal under control of the second control signal.
