In practical application scene, touch screen capacitance variation concrete reason is caused to have following two：
Reason one, capacitive touch screen posts particulate metal conductive materials of layer of transparent in glass surface, when finger touches
When touching on the metal layer, the capacitance of contact will change.
Reason two, capacitive touch screen is highly susceptible to electromagnetic interference, when there being electromagnetic interference, from either internally or externally

Situation two, capacitance are less than the capacitance threshold value of systemic presupposition, abandon this capacitance, terminate current operation and enter again
Wait reception state.
It should be noted that in above judge process, capacitance threshold value is more than pressure threshold, and these are only pin of the present invention
It is whether a kind of preferred embodiment of maloperation to this trigger action, on the basis of with this result as basis for estimation, specifically
The difference of judgment mode have no effect on protection scope of the present invention.
In addition it is also necessary to explanation is it is contemplated that when capacitance is more than default capacitance threshold value it is also possible to due to former
The charge movement producing because of interference voltage in two and the capacitance variation causing, belong to maloperation, and improper trigger action,
Therefore, after the capacitance obtaining being processed and got coordinate figure by conventional algorithm, it is additionally added in this step
The Rule of judgment of pressure value is filtered, by pressure sensing it is intended to be realized the second layer to maloperation by the detection of pressure value
The pressure value of device is incorporated in the testing conditions of the touch event of touch screen, increases the dimension of detection, improves touch operation and knows
Other accuracy.
In this step, the comparing result of pressure value and the pressure threshold of systemic presupposition is analyzed, also has following two feelings
Condition：
Situation one, pressure value exceed the pressure threshold of systemic presupposition, and coordinate figure is reported system, then terminate currently to grasp
Resume waiting for reception state as entrance.
Situation two, pressure value, not less than the pressure threshold of systemic presupposition, abandon this pressure value and coordinate figure, terminate current behaviour
Resume waiting for reception state as entrance.
Specifically, the concrete numerical value of pressure threshold can be configured according to actual needs, the change of concrete set content
Protection scope of the present invention can't be affected, in the present invention in order to the concrete numerical value of pressure threshold can be set by initialized operation
It is set to 0.
If step S303 exceedes described pressure threshold, described capacitance variations event is defined as touch event, will be described
Coordinate figure reports.
When pressure value exceedes the pressure threshold of systemic presupposition, determine that this capacitance variations event is touch event, and by coordinate
Value reports system.
