Abstract:
1. A display device comprising: a display panel unit including: 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.
