Abstract: A sensor device includes first sensors, second sensors, and a sensor driver. The first sensors are arranged along a first direction, and the second sensors are arranged along a second direction. The sensor driver is configured to transmit driving signals to the first sensors through first sensor lines and to receive sensing signals from the second sensors through second sensor lines. During a first period, the sensor driver is configured to transmit the driving signals to a first group of sensors, and to transmit offset signals having a frequency that is equal to that of the driving signals and a phase that is different from that of the driving signals to a second group of sensors. During a second period, the sensor driver is configured to transmit the offset signals to the first group of sensors and to transmit the driving signals to the second group of sensors.

Abstract: A display device includes a display panel including light-emitting regions and an input sensor disposed on the display panel and including sensing patterns. The sensing patterns include mesh lines defining opening regions respectively overlapping the light-emitting regions and protruding portions having a shape protruding from at least one of the mesh lines into the opening regions. The protruding portions include a first protruding portion disposed between light-emitting regions spaced apart from each other by a first distance in a first direction and a second protruding portion which is disposed between light-emitting regions spaced apart from each other by a second distance smaller than the first distance in the first direction and has a smaller area than the first protruding portion in a plan view, thereby exhibiting excellent display quality and viewing angle characteristics.
