Abstract: A resistive touch panel comprises a touch layer, a spacer layer, a sensing layer and a controller. The touch layer and sensing layer are separated by the spacer layer and respectively have a plurality of strip-like touch loops and a plurality of strip-like sensing loops arranged staggeredly up and down. The controller connects two terminals of the touch loops and sensing loops and controls voltages supplied thereto to enable a digital-mode driving and an analog-mode driving respectively corresponding to digital time series and analog time series that are alternately and consecutively provided. Thus the controller can perform multi touch and drag path, and select the digital-mode driving or analog-mode driving through a switch. Therefore is realized a resistive touch panel that is capable of operating in a multi-touch control mode and a sensing-drag control mode synchronously.

Abstract: The present invention discloses a multi-touch and handwriting-recognition resistive touchscreen, which comprises a touch layer, a spacer layer, a sensing layer and a controller. The touch layer and the sensing layer are separated by the spacer layer and respectively have a plurality of strip-like touch loops and a plurality of strip-like sensing loops. The touch layer is superimposed on the sensing layer with the touch loops oriented vertically to the sensing loops. The controller respectively connects to and supplies voltages to the two terminals of each touch loop and the two terminals of each sensing loop to enable a digital-mode driving and an analog-mode driving in different time intervals. The controller can integrate the multi-touch function and the handwriting-recognition function. Alternatively, a switch is used to switch the controller to operate in the digital mode enabling the multi-touch function or the analog mode enabling the handwriting-recognition function.
