20130314367 | Touch Gesture Identification Method for Surface Capacitive Touch Screen - The present invention relates to a touch gesture identification method for a surface capacitive touch screen, so as to identify touch gestures executed by at least two touching objects to the surface capacitive touch screen having a transparent substrate, an electrode layer and a transparent protection layer. The surface capacitive touch screen has advantages of simple framework, easy to be manufactured and low cost, so that this surface capacitive touch screen is widely applied in electronic and electrical products with different screen sizes. The main feature of the method is that the displaying images on the touch screen can be zoom in or zoom out by way of computing the difference between a first-time sensed current and a second-time sensed current resulted from the touch gestures executed by the two touching objects and detected by the surface capacitive touch screen. | 11-28-2013 |
