A display device, with a built-in touch sensor, including a display unit where sensor electrodes are provided, and a signal processing unit configured to process detection signals obtained from the sensor electrodes is provided with a segment-size switching unit configured to perform electrical connection and electrical disconnection of sensor electrodes such that a size of a segment serving as a unit of processing the detection signal becomes a size depending on an instruction signal. For example, the segment-size switching unit is configured by a switch circuit configured to switch a connection relationship between a plurality of sensor electrodes and a plurality of analog front ends, and a switching control unit configured to control operation of the switch circuit depending on the instruction signal.
A display device, with a built-in touch sensor, including a display unit where K sensor electrodes for touch detection are arranged in a matrix, where K is an integer of four or more, and a signal processing unit configured to process detection signals obtained from the K sensor electrodes, the display device comprising:
A drive method of a display device, with a built-in touch sensor, including a display unit where K sensor electrodes for touch detection are arranged in a matrix, where K is an integer of four or more, and a signal processing unit configured to process detection signals obtained from the K sensor electrodes, the drive method comprising:
