Claim:
1. An electronic device comprising: a display device comprising a plurality of first electrodes arranged in a matrix form, second electrodes opposite to the first electrodes, the second electrodes including a plurality of electrode patterns extending in a first direction and aligned in a second direction to cross the first direction, and third electrodes opposite to the second electrodes, the third electrodes including a plurality of electrode patterns extending in the second direction and aligned in the first direction; a display driver configured to apply a sensor drive signal to the plurality of electrode patterns of the second electrodes sequentially; and a detection circuit configured to transmit a detection data including physical quantity data detected from the plurality of electrode patterns of the third electrodes at each time when the sensor drive signal is applied to the plurality of electrode patterns of the second electrodes, wherein the detection circuit outputs an interruption request signal each time the detection circuit detects the physical quantity data from the plurality of electrode patterns of the third electrodes and transmits the detection data according to a response to the interruption request signal, the detection data includes an identification value which identifies an electrode pattern and a frame period which are driven at a time of detection, and the driven electrode pattern and the driven frame period are identified based on a horizontal period signal and a vertical period signal which the detection circuit receives from the display driver.
