Touch detecting device including a plurality of drive areas, display device with touch detecting function and electronic apparatus including the same

摘要

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.

1. A display apparatus with a touch detecting function comprising:
a touch detecting device including:
a first drive area and a second drive area each including a plurality of drive electrodes and a plurality of detection electrodes, the plurality of drive electrodes extending in a first direction, being arrayed in a second direction intersecting with the first direction, and configured to be applied with a drive signal serving as a signal for detecting at least one of approach and contact of an object, the plurality of detection electrodes extending in the second direction, being arrayed in the first direction, and configured to output a detection signal serving as a signal corresponding to a change in capacitance generated between the detection electrodes and the drive electrodes, the first drive area and the second drive area being arranged adjacent to each other in the second direction;a boundary between the first drive area and the second drive area adjacent to each other;a first boundary area and a first non-boundary area included in the first drive area; anda second boundary area and a second non-boundary area included in the second drive area, the first boundary area and the second boundary area facing each other with the boundary interposed therebetween; a display device integrated with the touch detecting device, wherein a direction of display scanning performed by the display device is different from a direction of touch detection scanning performed by the touch detecting device, wherein the drive signal is applied simultaneously to a first number of the drive electrodes in the first non-boundary area, and the drive signal is applied simultaneously to a second number of the drive electrodes in the second non-boundary area, wherein the drive signal is applied simultaneously to the first number of the drive electrodes in the first boundary area, and the drive signal is applied simultaneously to the second number of the drive electrodes in the second boundary area, wherein application of the drive signal to the drive electrodes arranged in the second drive area is stopped at a timing to apply the drive signal to one of the drive electrodes arranged in the first boundary area, wherein application of the drive signal to the drive electrodes arranged in the first drive area is stopped at a timing to apply the drive signal to one of the drive electrodes arranged in the second boundary area, and wherein the first number is different from the second number.
