US 9,804,704 B2 · Touch detecting device, display device with touch detecting function, and electronic apparatus

Abstract

According to an aspect, a touch detecting device includes: a first drive area and a second drive area each including drive electrodes and detection electrodes, the drive electrodes extending in a first direction, being arrayed in a second direction intersecting with the first direction, and being applied with a drive signal, the detection electrodes extending in the second direction, being arrayed in the first direction, and outputting a detection signal. Application of the drive signal to the drive electrodes in the second drive area is stopped at a timing to apply the drive signal to the drive electrodes arranged in a first predetermined area included in the first drive area, and application of the drive signal to the drive electrodes in the first drive area is stopped at a timing to apply the drive signal to a second predetermined area included in the second drive area.

Claims16

Dependent claims

A touch detecting device comprising:

a plurality of drive electrodes arranged in a first direction, in a first drive area and in a second drive area, the first drive area including a first boundary area and a first non-boundary area, and the second drive area including a second boundary area and a second non-boundary area, the first boundary area and the second boundary area being arranged adjacent to each other in the first direction;
and
a controller configured:
to supply a drive signal to a first number of the drive electrodes in the first non-boundary area, and to a second number of the drive electrodes in the second non-boundary area;
and
not to supply the drive signal to the first number of the drive electrodes in the first boundary area at a timing of supplying the drive signal to the second number of the drive electrodes in the second boundary area,
wherein the first number is different from the second number.
