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 display area; a pixel electrode; a plurality of scan lines; a plurality of data lines; an auxiliary wiring that is a wiring of a metal material having an electrical resistance lower than that of a material of the drive electrodes, is arranged so as to extend in the row direction for each row of the pixels, and is electrically coupled to the drive electrode; a control device that performs image display control and touch detection control; a touch detection electrode that faces the drive electrodes and forms a capacitance with the drive electrodes; and a touch detection unit that detects a position of a proximity object based on a detection signal sent from the touch detection electrode.

1. A display device with a touch detection function comprising:
a display area that has a plurality of pixels arranged in a matrix including a plurality of rows and a plurality of columns, in which one of the pixels includes a plurality of sub-pixels that represent mutually different colors and are arrayed in one column with k rows (k is a natural number of 3 or more), and in which arbitrary sub-pixels representing same color among arbitrary pixels that are adjacent to each other in a row direction are arrayed along the row direction; a display function layer that has an image display function for displaying an image in the display area; a pixel electrode that is provided in each of the sub-pixels and supplies an applied voltage to the display function layer by a potential difference with a common potential which is a reference; a plurality of scan lines that extend in the row direction of the display area and scan switching elements of the sub-pixels; a plurality of data lines that extend in a column direction of the display area and supply an applied voltage to the pixel electrodes; a plurality of drive electrodes that are provided facing the pixel electrodes and extend in the row direction; an auxiliary wiring that is a wiring of a metal material having an electrical resistance lower than that of a material of the drive electrodes, is arranged so as to extend in the row direction for each row of the pixels, and is electrically coupled to the drive electrode; a control device that performs image display control so as to apply the common potential to the drive electrodes based on an image signal to achieve the image display function of the display function layer, and that performs touch detection control so as to supply a drive signal for touch to the drive electrodes; a touch detection electrode that faces the drive electrodes and forms a capacitance with the drive electrodes; and a touch detection unit that detects a position of a proximity object based on a detection signal sent from the touch detection electrode.
