Abstract
An electronic device includes: a display layer displaying an image; a driving controller receiving an input image signal and a control signal and outputting a horizontal synchronization signal and image data; a data driving circuit configured to provide a data signal to the display layer in response to the horizontal synchronization signal and the image data; a sensor layer on the display layer; and a sensor driver driving the sensor layer and receiving sensing signals, wherein the sensor driver is configured to: output a horizontal synchronization control signal of a first level during a touch sensing mode of detecting a touch input; and output the horizontal synchronization control signal of a second level different from the first level during a pen sensing mode of detecting a pen input, and the driving controller changes a horizontal period of the horizontal synchronization signal in response to the horizontal synchronization control signal.
