Weight pressure process method and system of self capacitive touch screen
The present invention relates to touch screen technology, and provide a weight pressure process method and system of the self capacitive touch screen. In the weight pressure process method and system of the self capacitive touch screen provided by the invention, a threshold relationship is used to modify the existing touch threshold, the threshold relationship uses the touch threshold and the minor change of the changes of two channels adjacent to the channel corresponding to the maximum value as variables, if the maximum value is not greater than the value of the threshold relationship, identify the point causing the current change as a fake point and filter out the fake point. In the method, the change of the self capacitor caused by the deformation due to pressure, so the actual touch point can be identified more accurately, a touch application can be performed correctly, and the user experience is improved greatly.
