1. A touch detection method applied to a touch screen combining mutual-capacitance detection and self-capacitance detection, the method comprising:

  • determining, using a detection result of a first detection process, whether a touch signal is generated on a screen body of the touch screen, to obtain a first determination result, wherein the first detection process is a Y-direction electrode array detection, an X-direction electrode array detection or an XY-direction electrode array detection;

    in the case that the first determination result indicating that no touch signal is generated on the screen body of the touch screen is obtained, shielding a detection process that has not been executed, wherein the detection process that has not been executed is a detection process among three detection processes comprising the Y-direction electrode array detection, the X-direction electrode array detection and the XY-direction electrode array detection, which is different from the first detection process;

    in the case that the first determination result indicating that a touch signal is generated on the screen body of the touch screen is obtained, determining the touch type of the touch signal according to a detection result of the first detection process or a second detection process, to obtain a second determination result, wherein the touch type comprises single-touch and multi-touch, and the second detection process is one of the three detection processes which is different from the first detection process;

    in the case that the second determination result indicating that the touch signal is a multi-touch signal is obtained, refraining from starting a self-capacitance detection process that has not been executed; and

    obtaining touch information corresponding to the touch signal according to the detection results of the detection processes that have been executed.
