Patent ID: 11960672
Assignee: JAPAN DISPLAY INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 6:
7. A display device comprising:
a signal line;
a pixel electrode;
a drive electrode opposed to the pixel electrode;
scanning lines; and
display periods and a detection period in one of unit drive periods, the unit drive periods forming a frame period, and, the detection period not overlapping the display periods in the one of unit drive periods,
wherein during one of the display periods,
a display operation with respect to a horizontal line of an image is performed,
touch detections are not performed,
a common voltage is applied to the drive electrode,
a scanning signal is applied to one of the scanning lines and is not applied to a rest of the scanning lines, the one of the scanning lines being used for the display operation with respect to the horizontal line of the image,
a pixel signal is applied to the pixel electrode,
wherein, during the detection period,
the touch detections are performed and the display operation with respect to the horizontal line of the image is not performed,
an AC drive signal or a pulse drive signal is applied to the drive electrode, the AC drive signal or the pulse drive signal having pulses,
wherein during the display periods,
a scanning signal is applied to some of the scanning lines sequentially, the some of the scanning lines include the one of the scanning lines, and
wherein a number of the pulses during the detection period is more than a number of the some of the scanning lines.
