摘要： A display device includes sensor electrodes for sensing a touch. The sensor electrodes may also be used as an antenna. A display circuit board of the display device includes a radio signal connection unit for providing touch sensing signals and radio reception signals of the sensor electrodes to a touch driving circuit and an antenna driving circuit. Therefore, the display device not only senses a user's touch using the sensor electrodes but also conducts mobile communication using the sensor electrodes. For example, sensor electrodes for sensing a touch may also be used as an antenna.

摘要： An input sensing device includes a first base layer, a plurality of first sensing electrodes, a plurality of second sensing electrodes, a plurality of third sensing electrodes, and a plurality of fourth sensing electrodes. The first sensing electrodes are arranged on the first base layer along a first direction. The second sensing electrodes are arranged on the first base layer in different rows from the first sensing electrodes. The third sensing electrodes are arranged on the second sensing electrodes along a second direction different from the first direction. The third sensing electrodes overlap the second sensing electrodes. The fourth sensing electrodes are arranged on the same layer as the third sensing electrodes and overlap the first sensing electrodes. A constant voltage is applied to the third sensing electrodes during a touch pressure sensing operation.
