ABSTRACT:
A touch sensor array system includes a row and column array of individual sensing elements each of which has a bistable circuit arranged to adopt one of the other of its two stable state in dependence upon whether or not a touch input, by e.g. a stylus or finger, exists at the sensing element location. The rows of sensing elements are periodically reset in sequence by a scanning address circuit and the states of their bistable circuits are determined at regular intervals related to resetting by a detection circuit using active matrix addressing of the sensing elements. Each sensing element includes a switching device. The array of sensing elements is fabricated using thin film, e.g. TFT, technology so that high resolution is possible. The system can be used as an overlay to a display device, e.g. a matrix liquid crystal display device.
