TOUCH SENSOR DEVICE, DISPLAY DEVICE AND ELECTRONIC EQUIPMENT

摘要

The touch sensor device and the display device include: a panel unit having a touch detection area in which a plurality of drive electrodes extend in an X-direction, a plurality of detection electrodes extend in a Y-direction, and a plurality of detection units each composed of a pair of the drive electrode and the detection electrode are formed in a matrix pattern; the drive electrodes each having a width forming two detection units in the Y-direction; and regions each formed by the intersection between one drive electrode and first to fourth detection electrodes. In this region, detection regions having a first sensitivity in which first to fourth detection units are provided and non-detection regions having a second sensitivity are alternately disposed. For example, the detection electrodes have different shapes between the detection region and the non-detection region.

1. A display device comprising:
a display panel unit including:
a touch detection area having:
a plurality of drive electrodes used for both of display driving and touch driving and extending in a first direction,a plurality of detection electrodes extending in a second direction, anda plurality of detection units each composed of a pair of the drive electrode and the detection electrode, the plurality of detection units being formed in a matrix pattern,a display area in which pixels are formed in a matrix pattern, anda display functional layer which is controlled by the pixels and used for displaying an image on the display area; a first circuit unit which generates a signal for the display driving and an input signal for the touch driving and applies the signals to the plurality of drive electrodes; a second circuit unit which detects an output signal from the plurality of detection electrodes based on the input signal for the touch driving; a third circuit unit which applies the signal for the display driving to the pixels in the display area; the plurality of drive electrodes each having a width forming two detection units in the second direction; first to fourth detection electrodes of the plurality of detection electrodes; a plurality of touch detection regions which are provided in the touch detection area, formed by respective intersections between the plurality of drive electrodes and the first to fourth detection electrodes, and repeatedly disposed in the first direction and the second direction; first detection regions with a first sensitivity, which are provided in each of the plurality of touch detection regions and have first to fourth detection units; and second detection regions with a second sensitivity lower than the first sensitivity, which are provided in each of the plurality of touch detection regions, wherein at least either the plurality of drive electrodes or the plurality of detection electrodes have different shapes between the first detection region and the second detection region, the first detection regions and the second detection regions are alternately disposed in the first direction and the second direction, and when a first input signal is applied to each of the plurality of drive electrodes, four output signals are obtained from the first to fourth detection electrodes through the first to fourth detection units in each of the plurality of touch detection regions.
