Description
Technical Field
The invention relates to the field of communication, in particular to a method and a device for preventing key failure of a touch screen.
Background
Touch screens are transparent media attached to the surface of a display, and currently, the touch screens are mainly of the following types: resistive, surface capacitive and inductive capacitive, surface acoustic wave, infrared, etc. Among them, capacitive touch screen is more widely used, mainly involving communication and consumer electronics, such as: smart phones, mobile phones, multimedia players, PADs, etc.
The capacitive touch screen judges a touch point by sensing capacitance change generated by human body touch. It has two sets of signal lines: the driving line emits signals, and the sensing line detects the change of the capacitance value. When a finger touches the metal layer, the finger and the surface of the touch screen form a coupling capacitor due to the existence of an electric field of a human body, and for high-frequency current, the capacitor is a direct conductor, so that the finger sucks a small current from a contact point. The coupling between the two electrodes near the touch point is affected, thereby changing the capacitance between the two electrodes. When the mutual capacitance is detected, the electrodes in the driving line direction sequentially send out excitation signals, and all the electrodes in the sensing line direction simultaneously receive the signals, so that the change of capacitance values of all the intersection points of the transverse electrodes and the longitudinal electrodes, namely the capacitance of the two-dimensional plane of the whole touch screen, can calculate the coordinate of each touch point according to the two-dimensional capacitance variation data of the touch screen, and therefore, even if a plurality of touch points exist on the touch screen, the real coordinate of each touch point can also be calculated.
With the progress of the technology of the handheld touch screen mobile communication terminal, users using the handheld touch screen mobile communication terminal are increasing, and especially large-size touch screen devices are more popular among the users. However, the touch screen devices with larger and larger sizes make the operation of the touch screen device more and more difficult for a user to operate with one hand, when the user holds one hand, the holding hand can touch the touch screen inadvertently, and at the moment, the user operates the screen (including the touch screen keys at the bottom of the screen) with the other hand without any effect, so that the operation and experience of the user are affected.

And the values may be different from top to bottom and from left to right. For example, if the distance is 5mm from the left edge, the first coordinate range is 5mm, the first predetermined range is also 5mm, and all points in the point coordinate range of the touch screen, which is 5mm from the left edge, belong to the points touched by mistake. Similarly, the distance from the right edge can be set to 6 mm. Or 4mm is arranged above the edge, the second coordinate range is 4mm, the second preset range is 4mm, and the touch screen belongs to the point touched by mistake within the point coordinate range which is 4mm away from the upper edge. Similarly, 3mm from the edge may be provided below the edge, and so on. The user can set the value range autonomously.
S104: when the first touch instruction is mistaken touch, detecting whether a second touch instruction exists at the same time;
