[0003] During the normal touch process, the sensing value of the finger pressing area is positive, but when the finger presses the touch screen hard, the touch capacitance value changes due to the deformation of the touch screen, and there will be an induction around the finger pressing area. Abnormal value (the sensing value of the touch node in a large area becomes a negative value), and when the finger is lifted, it takes a certain time for the deformation generated in the touch screen to return to the normal state, so during this period There are still abnormalities in the induction value
Regardless of whether there is a touch operation or not, once more touch nodes with negative sensing values are detected in the touch area, the touch reference value calibration mechanism will be automatically triggered to change the touch reference value of each touch node , so that the sensing value of each touch node tends to 0. Due to the large positive and negative difference between the adjacent area (the area pressed by the finger and the surrounding area), deviations are prone to occur during the calibration process, resulting in the touch of the area pressed by the finger The sensing value of the node changes from a positive value to a negative value (that is, the phenomenon of disconnection), and the sensing value of the touch nodes in the area around the finger pressing area changes from a negative value to a positive value. Since the number of touch nodes with positive sensing values exceeds that of the touch Control the threshold, the touch screen mistakenly judges the area where the positive touch nodes are located as the finger operation area, resulting in false touches

The embodiment of the invention provides a touch calibration method and device, a storage medium and electronic equipment. The touch calibration method comprises the steps that when it is detected that an induction value of a touch node in a touch area is abnormal, whether touch operation exists in the touch area is judged; if not, calibrating the touch reference value of the touch node in the touch area when the touch area meets the first preset condition; and if yes, calibrating the induction value of the touch control node in the touch control area. When it is detected that the touch screen is abnormal, the corresponding touch calibration mechanism is started according to different touch states to calibrate the screen, the problem that the screen is touched by mistake due to automatic triggering of the calibration mechanism is avoided, and the touch accuracy is improved.
Description
technical field [0001] The present application relates to the field of touch technology, and in particular to a touch calibration method, device, storage medium and electronic equipment. Background technique [0002] With the continuous development of touch technology, the touch technology has been widely used, and many electronic devices equipped with touch screens appear on the market, and users can control the electronic devices by performing touch operations on the touch screen. [0003] During the normal touch process, the sensing value of the finger pressing area is positive, but when the finger presses the touch screen hard, due to the deformation of the touch screen, the touch capacitance value changes, and there will be an induction around the finger pressing area. Value abnormality (the sensing value of the touch node in a large area becomes a negative value), and when the finger is lifted, it takes a certain time for the deformation generated in the touch screen t...
