Touch screen control method and device

The invention relates to a touch screen control method and device, and belongs to the technical field of touch control of screens. The touch screen control method comprises the following steps: acquiring the actual capacitance values of all testing points on a touch screen; determining the interference level of a conducting liquid according to the variation of an actual capacitance value relative to a reference capacitance value, wherein the reference capacitance value is the capacitance value when the testing points are not influenced by conducting media; controlling the touch screen to be in an operation mode corresponding to the interference level. The invention solves the problem that when the conducting liquid covers the surface of the capacitive touch screen, the sensitivity and the detection precision of the capacitive touch screen are seriously influenced; the touch screen is controlled to be in the operating mode corresponding to the interference level according to the interference level of the conducting liquid, the influence of the conducting liquid on the touch screen is reduced to a great degree, and the sensitivity and the detection precision of the touch screen are improved.
