The capacitive touch screen is formed by sticking a layer of transparent special conductive substance on the surface of glass. When a finger touches the conductive layer, the capacitance of a touch point changes, so that the frequency of an oscillator connected with the touch point changes, and the touch position can be determined by measuring the frequency change to obtain information.
In an embodiment, a method for detecting a touch panel false touch operation is provided, which may be applied to an electronic device having a capacitive touch screen and operated by a processor in the electronic device, as shown in fig. 1, the electronic device includes a touch panel, a transition (dummy) area is disposed between a display area of the touch panel and a panel outer frame, the transition area includes a plurality of first-type sensing channels, the display area includes a plurality of second-type sensing channels, where the transition area may be a metal trace disposed outside the display area, and the sensing channels may be understood as nodes in a screen. The first type of sensing channel does not participate in the calculation of the touch position for the sensing quantity of the user touch behavior, and is used for judging whether the user touch behavior is a false touch operation or not; the second type of sensing channel user carries out the calculation of touch position, simultaneously, also can be used for the supplementary judgement user's touch action whether for the operation of mistake touch. When a finger of a user touches the first type of sensing channel in the transition area or the second type of sensing channel in the display area, the sensing quantity of the sensing channels changes, and therefore the touch behavior of the user can be identified.
It should be noted that, in the drawings of the embodiments of the present application, the form of the first type of sensing channel and the second type of sensing channel is only an example, and in an actual processing process, the arrangement form of the first type of sensing channel and the second type of sensing channel may be adjusted according to an actual situation, which is not specifically limited herein.

The processor acquires the induction quantities of all induction channels in the touch panel in real time, and for the capacitive touch screen, the induction quantities are specifically capacitance values, namely the processor detects the capacitance values of the first type of induction channels and the second type of induction channels and compares the obtained capacitance values with a preset threshold value, so as to determine whether touch operation exists on the touch panel.
Step S200, acquiring the capacitance induction information of the first type of induction channel in the transition area and the capacitance induction information of the second type of induction channel in the display area.
After determining that the touch operation exists on the touch panel, the processor acquires capacitance sensing information of the sensing channels in the transition area and the display area so as to detect the false touch operation of the touch panel.

The operation types include a normal touch operation and a false touch operation. After the capacitance sensing information of the sensing channel is obtained, the processor may determine whether the touch operation is a normal touch operation or a false touch operation according to the capacitance sensing information of the first type of sensing channel in the transition area, or determine whether the touch operation is a normal touch operation or a false touch operation according to the capacitance sensing information of the second type of sensing channel in the display area on the basis of the capacitance sensing information of the first type of sensing channel.
And step S410, when the touch operation is determined to be normal touch operation, determining the touch point coordinate corresponding to the touch operation according to the capacitance sensing information of the second type of sensing channel.
After determining that the touch operation is a normal touch operation, the processor executes a normal touch position determination process, and performs subsequent operations, for example, reporting the obtained touch point coordinates, and the like.
In step S420, when it is determined that the touch operation is the erroneous touch operation, the touch operation is not responded.
After determining that the touch operation is the false touch operation, the processor directly does not respond to the touch operation, and does not execute a normal touch position determination process.

The second preset threshold may be obtained according to big data analysis, for example, the induction quantity in the transition region is 30pF to 50pF through big data analysis, and therefore, the second preset threshold may be set to 30pF, and when the capacitance value of at least one first type induction channel is greater than 30pF, it is determined that a touch operation exists on the touch panel.

Specifically, the first capacitance threshold and the first time threshold may be obtained according to big data analysis, for example, the capacitance value of the induction value of the edge click obtained through big data analysis is usually 30pF to 50pF, and then the first capacitance threshold may be 30pF, and the first time threshold may be 200ms, which is not specifically limited herein, and may be adjusted according to actual conditions in an actual processing process.

Specifically, as shown in fig. 4, this embodiment deals with the situation that the touch screen has a touch of the edge of the tiger's mouth, which is the medical point of the valley, specifically, on the radial side of the back of the human index finger joint. The circular black point is the touch point that is located the transition region in the picture, and the treater detects that the capacitance value of the induction channel that corresponds the position is greater than the second electric capacity threshold value to when the quantity that the capacitance value is greater than the induction channel of second electric capacity threshold value is greater than first quantity threshold value, can think that there is the condition of marginal tiger's mouth touch in the transition region this moment, and under the normal operating condition, the user can not use the tiger's mouth to touch the transition region, thereby, the treater can judge that this touch operation belongs to the mistake touch operation.
Specifically, the second capacitance threshold and the first number threshold may be obtained according to big data analysis, for example, the capacitance value of the induction quantity of the edge web touch obtained through big data analysis is usually 60pF to 100pF, the second capacitance threshold may be 60pF, and the first number threshold may be 3, which is not specifically limited herein, and may be adjusted according to actual conditions in an actual processing process.

When the first capacitance value change trend information of the transition area is gradually decreased and the second capacitance value change trend information of the display area is gradually increased, the processor may determine that the touch center of gravity is shifted to the display area, that is, the user is operating the display area at the time, and the operation belongs to a normal user operation, so that the processor may determine that the touch operation belongs to a normal touch operation.
Specifically, when the capacitance value variation trend of the sensing channel is determined, the determination may be performed according to the capacitance value variation condition of a single sensing channel, for example, the number of the sensing channels having a capacitance value variation (excluding the condition that the capacitance value normally fluctuates in a small range) in the transition region is 3, and when the capacitance values of all the 3 sensing channels are reduced, it is determined that the first capacitance value variation trend information corresponding to the transition region is gradually reduced. In addition, when the sensing channels with the capacitance values being larger and smaller exist in the transition region at the same time, the change trend information is determined according to the channel number ratio of different change situations, for example, in 3 sensing channels, 1 is increased, and 2 is decreased, the change trend information of the first capacitance value corresponding to the transition region is determined to be gradually decreased.
The capacitance value change trend may be determined according to the average capacitance value change of the plurality of sensing channels, for example, the average capacitance value of 3 sensing channels at the i-th time is a (pf), the average capacitance value of 3 sensing channels at the i + 1-th time is b (pf), and if a > b, the capacitance value change trend is determined to be gradually reduced.

Specifically, the third capacitance threshold and the second number threshold may be obtained according to big data analysis, for example, the third capacitance threshold may be 100pF, the second number threshold may be 5, which is not specifically limited herein, and may be adjusted according to an actual situation in an actual processing process.

The circle black point in the graph is a touch point located in the transition area, the processor detects that the capacitance value of the induction channel at the corresponding position is larger than the second capacitance threshold value, and when the number of the non-connected areas formed by the induction channels is larger than the third number threshold value, the situation that the grabbing touch exists in the transition area at the moment can be considered, and under the normal operation situation, the user cannot grab the touch transition area, so that the processor can judge that the touch operation belongs to the error touch operation.
Specifically, the connected region refers to a region formed by connecting sensing channels in sequence and internally connected, for example, a region a71, a region a72, a region a73 and a region a74 formed by connecting sensing channels in sequence in fig. 7; the non-connected region refers to a region where an untouched sensing channel exists, for example, in fig. 7, the region a71 and the region a72 are not directly connected, but an untouched sensing channel exists, and therefore, the region a71 and the region a72 belong to the non-connected region. Similarly, the area a71, the area a72, the area a73 and the area a74 are all non-connected areas, that is, the number of the non-connected areas in fig. 7 is 4.
