11. A method of driving an electrostatic capacitance-type sensor-equipped display device comprising a display panel, the display panel including a first substrate, a second substrate which includes a display surface for displaying an image and is disposed opposite to the first substrate with a gap, a plurality of pixels, and a common electrode provided on the first substrate or the second substrate and shared by the pixels, each of the pixels including a pixel switching element formed on the first substrate and connected to a gate line and a source line, and a pixel electrode formed on the first substrate and connected to the pixel switching element, and the electrostatic capacitance-type sensor including a plurality of detection electrodes disposed in a matrix, mutually electrically independently provided above the display surface and configured to detect a variation in electrostatic capacitance, and a plurality of lead lines provided above the display surface, connected to the detection electrodes in a one-to-one correspondence, and formed of a metal, the method comprising:
-
delivering a control signal to the gate line and a video signal to the source line, in a display operation period, thereby driving the display panel, stopping an input of the control signal and the video signal to the display panel, and driving the electrostatic capacitance-type sensor, in an input position information detection period that does not overlap the display operation period; and writing a potential adjustment signal, which has the same waveform as a write signal which is written in the electrostatic capacitance-type sensor, in the common electrode in synchronism with the write signal, in the input position information detection period. - View Dependent Claims (12, 13, 14, 15, 16, 17)
