Abstract:
This application is directed to a display device that integrates a two-dimensional array of display elements and a two-dimensional array of capacitive sense elements. A common electrode layer includes a two-dimensional array of common electrodes, which are used in both display elements and capacitive sense elements. One or more sensing control interconnects and a plurality of driving interconnects are arranged in parallel with each other and on top of a first row of common electrodes. Each sensing control interconnect is configured to provide a touch sensing control signal to enable/disable electrical access to common electrodes in the first row of common electrodes in a touch sensing mode. Each common electrode in the first row is electrically coupled to two or more respective driving interconnects in a display driving mode, while each of the plurality of driving interconnects is electrically coupled to a single respective common electrode.
