Abstract: A display device includes a display panel, an input sensor disposed on the display panel and sensing an input during a sensing frame period, a display controller receiving a vertical synchronization signal and a horizontal synchronization signal and controlling driving of the display panel in response to the vertical synchronization signal and the horizontal synchronization signal, and a sensor controller providing a transmission signal including a plurality of sampling periods to the input sensor. The display controller provides frequency information of a display frame period to the sensor controller using at least one of the vertical synchronization signal and the horizontal synchronization signal, and the sensor controller controls the number of the sampling periods of the sensing frame period based on the frequency information.

Abstract: An electronic device includes a sensor in which a sensing area and a peripheral area proximate to the sensing area are defined, and a sensor driver driving the sensor. The sensor includes first electrodes disposed in the sensing area and arranged along a first direction, and second electrodes arranged along a second direction intersecting the first direction. A boundary extending along the second direction is defined in the sensing area. The sensor driver simultaneously outputs a plurality of boundary transmit signals to a plurality of boundary electrodes disposed in a boundary area including the boundary among the plurality of first electrodes.

Abstract: An electronic device includes: a sensor layer including a first area and a second area adjacent to the first area; a first driving circuit providing a first driving signal to the sensor layer and receiving first data output from the first area of the sensor layer; and a second driving circuit providing a second driving signal to the sensor layer and receiving second data output from the second area of the sensor layer. The second driving circuit provides intermediate data to the first driving circuit. The intermediate data is obtained based on the second data, and the first driving circuit generates result data based on the first data and the intermediate data.
