发明名称 TOUCH PANEL DEVICE AND TOUCH INPUT POINT SPACING DISTANCE DETECTION METHOD OF TOUCH PANEL
摘要 There are provided a touch panel apparatus and a method for detecting a distance between touch input points of a touch panel, with which it is possible to detect the distance between two points with accuracy, when two points are touched on the touch panel. Whether or not two points are touched on the touch panel TP is determined based upon a resistance value between terminals opposing each other. When it is determined that two points are touched, the distances between touched two points XDual and YDual are detected. In this situation, the distances between touched two points XDual and YDual are detected based upon the resistance value of the opposing terminals and a pressing force (contact resistance value) of the touch input points.
