Abstract
In one example embodiment, a display device includes a drive control section operatively coupled to a signal line and a display section. The signal line has a first voltage. In one example embodiment, the display section includes: (a) a touch detection element which outputs a touch voltage; and (b) an electrode which has a second voltage. In one example embodiment, the drive control section increases a potential difference between the first voltage and the second voltage before the touch detection element outputs the touch voltage.

A display device comprising:
- a drive control section;
- a signal line operatively coupled to the drive control section, the signal line having a first voltage;
- and
- a display section operatively coupled to the drive control section, the display section including:
- (a) a touch detection element configured to output a touch voltage;
- and (b) an electrode having a second voltage;

- and (ii) the second voltage of the electrode.
A method of operating a display device, the method comprising:
- causing a drive control section to, before a touch detection element of a display section outputs a touch voltage, increase a potential difference between:
- (i) a first voltage of a signal line;
- and (ii) a second voltage of an electrode of the display section.
A touch panel comprising:
- a drive control section;
- a signal line operatively coupled to the drive control section, the signal line having a first voltage;
- an electrode operatively coupled to the drive control section, the electrode having a second voltage;
- and
- a touch detection element configured to output a touch voltage;
- wherein the drive control section is configured to, before the touch detection element outputs the touch voltage, increase a potential difference between:
