First Claim
1. A display device comprising:
- a plurality of pixels each divided into two pixel areas;
a display functional layer that can change display for each pixel in accordance with an application voltage;
a plurality of driving electrodes, disposed in a first direction so as to be separated from one another, to which a display reference electric potential maintained at a constant level is applied during a display period in which display is performed in a pixel arrangement along the first direction and to which a detection driving signal is applied when detection scanning is performed by changing the display reference electric potential to another electric potential;
a plurality of pixel signal lines to which pixel signals used for applying the application voltage to the display functional layer in accordance with an electric potential difference from the display reference electric potential are applied;
a plurality of detection electrodes that are disposed so as to be separated from one another in a direction other than the first direction, are coupled with the plurality of the driving electrodes as electrostatic capacitance, generate detection electric potentials in response to the detection driving signal that is applied to at least one driving electrode; and
a pixel signal control unit that controls the plurality of pixel signals applied to the plurality of pixel signal lines so that two pulses of pixel signals, which include a pixel signal before being inverted and a pixel signal after being inverted are simultaneously applied to each of the two pixel areas.
