Display device
View Patent ↗A display device includes: a pixel array having pixels arranged in matrix and having a first side parallel to a row and a second side opposite to the first side; scanning lines arranged in each row of the pixel array to supply a scanning signal to the pixels arranged in a corresponding row; signal lines arranged in each column of the pixel array to supply an image signal to the pixels arranged in a corresponding column; drive electrodes arranged in a column of the pixel array and to which a drive signal to detect an external proximate object is supplied; and a first drive electrode circuit arranged along the first side and connected to control lines and the drive electrodes arranged in the pixel array to supply the drive signal to, among the drive electrodes, the drive electrode specified by a selection signal supplied via the control lines.
1. A display device comprising:
a pixel array including a plurality of pixels arranged in a matrix form and having a first side parallel to a row and a second side opposite to the first side;
a plurality of scanning lines arranged in each row of the pixel array to supply a scanning signal to the plurality of pixels arranged in a corresponding row;
a plurality of signal lines arranged in each column of the pixel array to supply an image signal to the plurality of pixels arranged in a corresponding column; a plurality of drive electrodes which are arranged in a column of the pixel array and to which a drive signal to detect an external proximate object is supplied; and
a first drive electrode circuit which is arranged along the first side of the pixel array and connected to a plurality of control lines and the plurality of drive electrodes arranged in the pixel array and supplies the drive signal to, among the plurality of drive electrodes, the drive electrode specified by a selection signal supplied via the plurality of control lines;
wherein at least some of the plurality of signal lines are the plurality of control lines.
2. The display device according to claim 1 , further comprising:
a signal line circuit arranged along the second side of the pixel array and connected to the plurality of signal lines,
wherein the signal line circuit supplies the image signal to the plurality of signal lines when an image is displayed in the pixel array.
3. The display device according to claim 2 , further comprising:
a touch control device which forms the selection signal specifying the drive electrode from the plurality of drive electrodes when the external proximate object is detected.
