Disclosed is a control method of a state of a touch screen. The touch screen comprises a touch sensor, and the touch sensor comprises a plurality of touch nodes. The control method comprises the following steps: S1, detecting that capacitance detection values of touch nodes in a preset specific region on the touch sensor change uniformly in a preset time length; S2, obtaining the number of touch nodes with changes of capacitance detection values greater than a preset capacitance detection value threshold; and S3, when the number of the touch nodes with the changes of the capacitance detection values greater than the preset capacitance detection value threshold is greater than a preset number, controlling the touch screen to perform state switching. According to the control method, change conditions of the capacitance detection values of the touch nodes in the preset specific region on the touch sensor are detected to implement control on the state of the touch screen, so that the control method is simple and convenient, no complex detection circuit needs to be set, and a cost is reduced. Further disclosed are a touch screen and a portable touch terminal provided with the touch screen. |
