Description

Capacitive screen touch point reporting method, electronic equipment and computer readable storage medium Technical Field The embodiment of the application relates to the technical field of display, in particular to a capacitive screen touch point reporting method, electronic equipment and a computer readable storage medium. Background Capacitive screens (which may also be referred to as capacitive touch screens, capacitive touch screens) are typically a four-layer composite glass screen. The inner surface layer and the interlayer of the glass screen are respectively coated with an Indium Tin Oxide (ITO), and the outermost layer is generally a thin silica glass protective layer. The interlayer ITO coating is used as a working surface, four electrodes are led out from four corners, and the inner layer ITO is a shielding layer so as to ensure a good working environment. Briefly, a capacitive screen is a screen in which the location of a touch point is determined by the change in screen capacitance after a user touches. At present, the capacitive screen is deformed under the action of external force, and the corresponding screen capacitance is also changed. However, after the capacitive screen is deformed by compression, the screen capacitance assumes a state gradually decreasing outward with the compression position as the center. Therefore, when the capacitive screen is stressed more severely and the screen deformation is more serious, the problems that the report point of the finger touch point disappears or the additional report point is generated due to the fact that no finger touch exists or the abnormality occurs due to the fact that the capacitance value of the stressed position is too high are easily caused. Disclosure of Invention The embodiment of the application provides a touch point reporting method of a capacitive screen, electronic equipment and a computer readable storage medium, which are used for solving the problem that the point reporting disappears or additional point reporting is generated due to severe compression of the capacitive screen. In order to achieve the above purpose, the embodiment of the present application adopts the following technical scheme: The first aspect provides a touch point reporting method of a capacitive screen, which comprises the steps of detecting that a user touches the capacitive screen by a finger, and firstly obtaining a first capacitance set, wherein the first capacitance set corresponds to an electrode array of the capacitive screen and comprises a plurality of capacitance values generated by the finger touching the capacitive screen. And then, if the sum of the absolute values of all the capacitance values in the first capacitance set reaches the total capacitance threshold, performing capacitance value deduction on the abnormal capacitance value in the first capacitance set to obtain a second capacitance set, wherein the abnormal capacitance value is a capacitance value in an abnormal capacitance range, and the second capacitance set comprises the capacitance value obtained after performing capacitance value deduction on the abnormal capacitance value and the capacitance value which is not subjected to capacitance value deduction. And finally, touch point reporting is carried out according to the second capacitor set. In the first aspect, the total capacitance threshold is used for indicating whether the strength of the finger touch of the user causes the screen to be deformed severely. Therefore, when the sum of the absolute values of the capacitance values reaches the total capacitance threshold, the fact that the finger touch force of the user is relatively large at this time and relatively severe screen deformation is caused can be determined. Furthermore, the abnormal capacitance value of the first capacitance set is detected, the abnormal capacitance value is raised or lowered through deduction processing, and the floating degree of the abnormal capacitance value is relieved, so that the problems that the report point is disappeared and an additional report point is generated due to the fact that the capacitance floats severely because of compression deformation are avoided, normal operation of a screen after compression is ensured, and the touch control effect of a product is ensured. In another possible implementation manner of the first aspect, the first set of capacitors may be a first capacitor matrix and the second set of capacitors may be a second capacitor matrix according to a characteristic of a lateral and longitudinal distribution of the electrode array in the capacitive screen. Therefore, in order to improve the accuracy of abnormal capacitance value detection. In this implementation, the detection of the abnormal capacitance value and the capacitance value subtraction process may be performed by traversing each row and/or each column in the first capacitance matrix. Based on the above, the capacitance value deduction is performed o
