Abstract:
1. A resistive touch panel capable of operating in a multi-touch control mode and a sensing-drag control mode synchronously, comprising: a touch layer including a plurality of strip-like touch loops, wherein each of the plurality of touch loops includes a first touch terminal, a second touch terminal, and two conductive contact layers respectively arranged at the first touch terminal and the second touch terminal; a spacer layer being formed at a selected thickness; a sensing layer including a plurality of strip-like sensing loops, wherein each of the plurality of sensing loops includes a first sensing terminal, a second sensing terminal, and two conductive contact layers respectively arranged at the first sensing terminal and the second sensing terminal, and wherein the touch layer and the sensing layer are separated by the spacer layer such that the touch loops and the sensing loops are arranged staggeredly up and down; and a controller connected to the first touch terminals, the second touch terminals, the first sensing terminals and the second sensing terminals via the conductive contact layers, wherein the controller automatically detects and outputs digital-mode voltages and analog-mode voltages respectively corresponding to a plurality of digital time series and a plurality of analog time series that are alternately and consecutively provided in an automatic operation mode, wherein in each of the plurality of digital time series, one digital-mode voltage is input to the first touch terminals and the first sensing terminals via the conductive contact layers, and when the touch loops and the sensing loops form short circuit, the controller detects a digital short-circuit position where the touch loops and the sensing loops are short-circuited and performs multi-touch judgment, and wherein in each of the plurality of analog time series, one analog-mode voltage is input to the first touch terminals via one conductive contact layer, and when the touch loops and the sensing loops form short circuit, the controller detects divided voltages of the second touch terminals, the first sensing terminals and the second sensing terminals and calculates to obtain an analog short-circuit position where the touch loops and the sensing loops are short-circuited and performs drag path judgment.
