Abstract

First electrodes include a left-side first electrode disposed on a left side of a virtual line bisecting a display region and passing through a geometric center of the display region, and a right-side first electrode disposed on a right side of the virtual line, and a detector includes a determination processor configured to determine a detection target moving from the left side to the right side to be a left-side user approaching from the left side based on a detection value of the left-side first electrode, and determine the detection target moving from the right side to the left side of the display region to be a right-side user approaching from the right side based on a detection value of the right-side first electrode.

Claims (14)

1 . A display device comprising:

a display panel including a display region configured to display an image;

a plurality of first electrodes provided in a frame region outside the display region;

a plurality of second electrodes provided in the display region; and

a detector configured to detect a detection target based on detection signals of the first electrodes, wherein

the first electrodes include a left-side first electrode disposed on a left side of a virtual line bisecting the display region and passing through a geometric center of the display region, and a right-side first electrode disposed on a right side of the virtual line, and

the detector includes a determination processor configured to

determine the detection target moving from the left side to the right side to be a left-side user approaching from the left side based on a detection value of the left-side first electrode, and

determine the detection target moving from the right side to the left side of the display region to be a right-side user approaching from the right side based on a detection value of the right-side first electrode.

2 . The display device according to claim 1 , further comprising a parallax barrier at a position overlapping the display panel, the parallax barrier being configured to distribute light having transmitted through the display panel to either one user or the other user, wherein the display panel allows a first image to be visually recognized by one user and a second image to be visually recognized by the other user.

3 . The display device according to claim 1 , wherein the determination processor disables operations by a left-side user approaching from the left side and enables operations by a right-side user approaching from the right side.

4 . The display device according to claim 1 , wherein the determination processor disables operations by a right-side user approaching from the right side and enables operations by a left-side user approaching from the left side.

5 . The display device according to claim 3 , wherein the determination processor enables operations by both a left-side user approaching from the left side and a right-side user approaching from the right side.

6 . The display device according to claim 4 , wherein the determination processor enables operations by both a left-side user approaching from the left side and a right-side user approaching from the right side.
