Abstract

A display device to be disposed in front of eyes of a user includes a display unit having a right-eye region and a left-eye region, a detector configured to detect detection information enabling estimation of a direction of a line of sight of the user, a setting unit configured to set display region information indicating display regions of the right-eye and left-eye regions, and a controller configured to output the display region information and the detection information to a control device. After receiving an image including a right-eye image and a left-eye image corresponding to the display regions indicated by the display region information from the control device, the controller displays the received right-eye image in the display region of the right-eye region indicated by the display region information, and display the received left-eye image in the display region of the left-eye region indicated by the display region information.

First claim

What is claimed is:

1. A display device to be disposed in front of both eyes of a user, the display device comprising:
a display panel having a right-eye region and a left-eye region;
a detector configured to detect detection information enabling estimation of a direction of a line of sight of the user;
a setting switch configured to set display region information indicating display regions of the right-eye region and the left-eye region each of which displays an image that follows the direction of the line of sight of the user; and
a controller configured to output the display region information of the setting switch and the detection information of the detector to a control device, wherein
the setting switch is configured to set, as the display region information, information that indicates a first mode of setting an entire region of the right-eye region and an entire region of the left-eye region as the display regions or a second mode of setting a partial region of the right-eye region and a partial region of the left-eye region as the display regions smaller than those in the first mode,
the controller is configured to:
display the received right-eye image in the display region of the right-eye region indicated by the display region information and display the received left-eye image in the display region of the left-eye region indicated by the display region information when the first mode is set by the setting switch; and
display the received right-eye image in the display region serving as the partial region of the right-eye region indicated by the display region information and display the received left-eye image in the display region serving as the partial region of the left-eye region indicated by the display region information when the second mode is set by the setting switch, and
when the second mode is set, a region other than the partial region of the right-eye region indicated by the display region information is a non-display region and a region other than the partial region of the left-eye region indicated by the display region information is a non-display region,
the display panel comprises a display panel including a plurality of scanning lines, and
the display panel is configured to, when the second mode is set, set a region including effective scanning lines in the plurality of scanning lines as the display region, and set a region including scanning lines different from the effective scanning lines as each non-display region.

2. The display device according to claim 1 , wherein
the setting switch is configured to set, as the display region information, information that indicates a first mode of displaying different images in the right-eye region and the left-eye region or a second mode of displaying the same image in the display regions of the right-eye region and the left-eye region, and
the controller is configured to:
display the received right-eye image in the display region of the right-eye region indicated by the display region information and display the received left-eye image in the display region of the left-eye region indicated by the display region information when the first mode is set by the setting switch; and
display, after receiving the image including only one of the right-eye image and the left-eye image corresponding to the display regions indicated by the display region information, the received image in both the display regions of the right-eye region and the left-eye region indicated by the display region information when the second mode is set by the setting switch.

3. The display device according to claim 1 , wherein
the setting switch is configured to set, as the display region information, information that indicates a first mode of setting an entire region of the right-eye region and an entire region of the left-eye region as the display regions or a second mode of setting a partial region of the right-eye region and a partial region of the left-eye region as the display regions smaller than those in the first mode and displaying the same image in the display regions, and
the controller is configured to:
display the received right-eye image in the display region of the right-eye region indicated by the display region information and display the received left-eye image in the display region of the left-eye region indicated by the display region information when the first mode is set by the setting switch; and
display, after receiving the image including only one of the right-eye image and the left-eye image corresponding to the display regions indicated by the display region information, the received image in both of the display regions that are the partial region of the right-eye region and the partial region of the left-eye region indicated by the display region information when the second mode is set by the setting switch.

4. A display system comprising:
the display device as claimed in claim 1 ; and
a control device configured to control display of an image on the display device, wherein
the control device comprises a second controller configured to output, to the display device, the image that follows the direction of the line of sight of the user and includes the right-eye image and the left-eye image corresponding to the display regions indicated by the display region information based on the detection information of the detector output by the display device.

5. A display device to be disposed in front of a user, the display device comprising:
a display panel having a right-eye region and a left-eye region;
a detector configured to detect detection information including a direction and movement of a line of sight of the user; and
a controller configured to output the detection information of the detector and a display region information to a control device, the display region information including positional information on a first display region positioned in the right-eye region and positional information on a second display region positioned in the left-eye region, wherein
the control device is configured to output a first image signal of a right-eye image and a second image signal of a left-eye image to the controller,
the controller is configured to display the right-eye image in the first display region and the left-eye image in the second display region,
the display device has
a first mode in which an entire region of the right-eye region is the first display region and an entire region of the left-eye region is the second display region, and
a second mode in which a partial region of the right-eye region is the first display region and a partial region of the left-eye region is the second display region,
when in the second mode, a region other than the partial region of the right-eye region that is the first display region is a non-display region and a region other than the partial region of the left-eye region that is the second display region is a non-display region,
the display panel includes a plurality of pixels, and
the display region information includes the number of pixels and pixel density of the first display region and the number of pixels and pixel density of the second display region.

6. The display device according to claim 5 , wherein a position of the first display region and a position of the second display region are configured to change.

7. The display device according to claim 5 , wherein the right-eye image and the left-eye image are changed depending on the detection information.

8. The display device according to claim 7 , wherein a position of the first display region and a position of the second display region are configured to change.

9. The display device according to claim 5 , wherein the detector is configured
