Zusammenfassung: | A touch display device includes a display panel, a plurality of receive electrodes, an enable electrode driver, and a touch sense circuit. The display panel includes a plurality of data electrodes and a plurality of enable electrodes connected to a plurality of display cells. Each display cell is connected to a pair of an enable electrode and a data electrode. The enable electrode driver drives a first enable electrode with a display voltage to activate display cells coupled to the first enable electrode, and drives a second enable electrode different than the first enable electrode with a transmit voltage to produce a capacitive coupling between the second enable electrode and a receive electrode. The touch sense circuit is configured to recognize a touch input to the touch display device based on a change in capacitance between the second enable electrode and the receive electrode. |
