Classification: CPC G | IPC G

Claim 3:
4. The display touch device according to claim 1, wherein the power supply control sub-circuit comprises a first switch sub-circuit, a second switch sub-circuit, a first inversion sub-circuit and a second inversion sub-circuit;
the first inversion sub-circuit is configured to perform phase inversion on the control signal to obtain a first inversion voltage signal, and provide the first inversion voltage signal to a control terminal of the second switch sub-circuit and the second inversion sub-circuit;
the second inversion sub-circuit is configured to perform phase inversion on the first inversion voltage signal to obtain a second inversion voltage signal, and provide the second inversion voltage signal to a control terminal of the first switch sub-circuit;
the first switch sub-circuit is configured to control to connect the display power supply terminal and the voltage input terminal when the second inversion voltage signal is the first voltage signal, and control to disconnect the display power supply terminal from the voltage input terminal when the second inversion voltage signal is the second voltage signal;
the second switch sub-circuit is configured to control to connect the touch power supply terminal and the voltage input terminal when the first inversion voltage signal is the first voltage signal, and control to disconnect the touch power supply terminal from the voltage input terminal when the first inversion voltage signal is the second voltage signal.
