DISPLAY DEVICE WITH TOUCH DETECTION FUNCTION AND ELECTRONIC APPARATUS |
摘要 |
According to an aspect, a display device with a touch detection function includes a plurality of drive electrodes that face a plurality of pixel electrodes in an orthogonal direction to the surface of the substrate, and extend in a direction parallel to the direction in which a plurality of signal lines extend. The display device with a touch detection function also includes a scan driving unit that applies a touch drive signal to a signal line that faces, in an overlapping manner in the orthogonal direction, a drive electrode to which the touch drive signal is applied. |

1. A display device with a touch detection function comprising:
a substrate; a plurality of pixel electrodes that are arranged in rows and columns in a plane parallel to the substrate; a plurality of signal lines that extend in a plane parallel to a surface of the substrate, and supply pixel signals for displaying an image on the plurality of pixel electrodes; a display function layer that exerts an image display function based on the pixel signals; a plurality of drive electrodes that face the plurality of pixel electrodes in an orthogonal direction to the surface of the substrate, and extend in a direction parallel to the direction in which the plurality of signal lines extend; a plurality of touch detection electrodes that face the plurality of drive electrodes in the orthogonal direction, extend in a direction different from the direction in which the plurality of signal lines extend, and capacitively couple with the plurality of drive electrodes; and a scan driving unit that scans the plurality of drive electrodes, and applies thereto a touch drive signal for touch detection, wherein the scan driving unit applies the touch drive signal to a signal line that faces, in an overlapping manner in the orthogonal direction, a drive electrode to which the touch drive signal is applied.
