interactive touch screen board.Point A is the first place where the touch event occurred . After detection, the first set of positioning coordinate data is generated , which can be collected to the actual place where the first touch event occurs. When the user touches point D after leaving point A to generate a second set of touch signals, the actual location of the second touch event can be collected. At a given time, when both points A and D are pressed , the first group of signals and the second group of signals will overlap during this time, and the microprocessor will calculate multiple position coordinate data, which is The touch point may be one of points A , B , C , and D , so that the touch screen cannot properly respond to the user's operation .
