MULTI-TOUCH AND HANDWRITING-RECOGNITION RESISTIVE TOUCHSCREEN

摘要

The present invention discloses a multi-touch and handwriting recognition resistive touch screen including a touch layer, a spacer layer, a sensing layer, and a controller. The touch layer and the sensing layer are spaced apart by a spacer layer and have a plurality of stripped touch loops and a plurality of stripped sensing loops, respectively. The touch layer is superimposed on the sensing layer with the touch loops orthogonal to the sensing loops. The controller is connected to two terminals of each touch loop and two terminals of each sensing loop to supply voltages so as to enable digital mode driving and analog mode driving at different time zones. The controller can integrate a multi-touch function and a handwriting recognition function. On the other hand, the switch is used to switch the controller to operate in the digital mode with the multi-touch function or the analog mode with the handwriting recognition function. ; Multi-touch, handwriting recognition, resistive, touch screen, touch layer, spacer layer, sensing layer, controller, spacer layer, strip type touch loop, strip type sensing loop, switch
