Conventionally,, under the effect of different driving voltages, capacitance type sensor is suitable for surveying the electric field of different distance; Driving voltage is larger, and capacitance type sensor is suitable for surveying more remote electric field.

Alternatively, described at least two driving voltages are corresponding one by one with space, at least two, front of described touch-screen.Particularly, under the effect of each driving voltage, the capacitance profile of described multiple capacitance type sensors can more accurately be reflected to the distribution of electric field in the space that this driving voltage is corresponding.Wherein, due to the magnitude of voltage difference of described at least two driving voltages, the distance of described at least two spaces and described touch-screen, distance range in other words, conventionally also different.Alternatively, the distance range of described at least two spaces and described touch-screen can be overlapping, or not overlapping, the present embodiment is not construed as limiting this.

For instance, the space that a driving voltage is corresponding and the distance range of described touch-screen are [5 centimetres, 10 centimetres], and the space that another driving voltage is corresponding and the distance range of described touch-screen are [20 centimetres, 30 centimetres]; Again for instance, the space that a driving voltage is corresponding and the distance range of touch-screen are [5 centimetres, 15 centimetres], and the space that another driving voltage is corresponding and the distance range of described touch-screen are [12 centimetres, 30 centimetres].

The method of the present embodiment is described further below by some optional implementations.

The present embodiment 110 in, can successively encourage the multiple capacitance type sensors in described touch-screen with the each driving voltage in described at least two driving voltages in sequence, particularly, the excitation order of described at least two driving voltages can be arbitrarily, or, set the adjustment strategy of driving voltage according to the applied environment of described touch-screen, or, driving voltage next time adjusted according to the capacitance profile obtaining before.

In the optional implementation of one, described in obtain the capacitance profile of multiple capacitance type sensors under at least two driving voltages in described touch-screen, comprising:

Obtain the capacitance profile of multiple the first capacitance type sensors under one first driving voltage in described touch-screen;

Obtain the capacitance profile of multiple the second capacitance type sensors under one second driving voltage that is different from described the first driving voltage in described touch-screen.

That is to say, can be first with multiple the first capacitance type sensors in touch-screen described in the first activation voltage, obtain the capacitance profile of described multiple the first capacitance type sensors, with multiple the second capacitance type sensors in touch-screen described in the second activation voltage, obtain the capacitance profile of described multiple the second capacitance type sensors again.

A kind of possible scene is that it can be pre-set encouraging which capacitance type sensor in described touch-screen at every turn.Particularly, described multiple the first capacitance type sensors can be identical with described multiple the second capacitance type sensors, or, difference.
