Abstract
According to one embodiment, a display device includes a display part, a plurality of sensor electrodes and a controller. The display part is configured to display an image. The plurality of sensor electrodes are arranged to surround the display part. The controller is electrically connected to the sensor electrodes, and is configured to detect an object close to or contacting the sensor electrodes. The controller drives at least one of the sensor electrodes as a detection electrode and drives at least one of the sensor electrodes as a drive electrode.
Claims19
A display device comprising:
- a display part configured to display an image;
- a plurality of sensor electrodes arranged to surround the display part;
- and
- a controller electrically connected to the sensor electrodes, and configured to detect an object close to or contacting the sensor electrodes, wherein
- the plurality of sensor electrodes are circularly arranged in series to surround the display part,
- width of each of the sensor electrodes is maximized in a center part,
- each of the sensor electrodes includes a connecting part to be electrically connected to the controller, in the center part,
- each of the connecting parts are located such that as the connecting part is located closer to the controller, the connecting part is closer to the display part, and
- the controller drives at least one of the sensor electrodes as a detection electrode and drives at least one of the sensor electrodes as a drive electrode.
