Abstract: A touch display device including sensing electrodes arranged on a single layer of a touch panel and a touch detection circuit configured to determine whether an object touched the touch panel by a voltage detected by the sensing electrodes. The sensing electrodes include a first group including two first sensing electrodes spaced apart by having a second sensing electrode interposed between the two first sensing electrodes. The first group is connected to the touch detection circuit through one wire. The sensing electrodes also include a second group including one second sensing electrode. The second group is connected to the touch detection circuit through one wire.

Abstract: A display device includes a display panel, a signal controller, sensing signal lines, and a touch sensor controller. The display panel includes pixels configured to display images, and touch sensor electrodes configured to sense a touch event. The touch sensor electrodes overlap a conductive layer. The signal controller is configured to generate signals to control the display of the images via the display panel. The sensing signal lines are respectively connected to the touch sensor electrodes. The touch sensor controller is configured to transmit a sensing input signal via the sensing signal lines, receive a sensing output signal via the sensing signal lines, and generate touch information based on reception of the sensing output signal. The touch sensor controller is configured to apply the same signal to the touch sensor electrodes and the conductive layer.
