Three-dimensional display apparatus, three-dimensional display system, head-up display system, and mobile body

A three-dimensional display system comprising:

• a detection apparatus configured to detect a position of a user's eye;
• and
• a three-dimensional display apparatus that includes:
• a display surface formed as a curved surface that does not have curvature in a first direction and has curvature in a plane orthogonal to the first direction, the display surface including a plurality of subpixels arranged in a grid pattern along the first direction and a direction in the display surface that is orthogonal to the first direction;
• an optical element that is arranged to follow the curved surface and defines a beam direction of image light emitted from each of the plurality of subpixels for each of a plurality of strip-shaped regions extending in a certain direction in a surface following the curved surface;
• and
• a controller configured to acquire the position of the user's eye and change an image displayed by each of the plurality of subpixels based on the display surface, the optical element, and the position of the user's eye.

A head-up display system comprising:

• a three-dimensional display apparatus that includes:
• a display surface formed as a curved surface that does not have curvature in a first direction and has curvature in a plane orthogonal to the first direction, the display surface including a plurality of subpixels arranged in a grid pattern along the first direction and a direction in the display surface that is orthogonal to the first direction;
• an optical element that is arranged to follow the curved surface and defines a beam direction of image light emitted from each of the plurality of subpixels for each of a plurality of strip-shaped regions extending in a certain direction in a surface following the curved surface;
• and
• a controller configured to acquire a position of a user's eye and change an image displayed by each of the plurality of subpixels based on the display surface, the optical element, and the position of the user's eye.

A mobile body comprising:

• a three-dimensional display system that includes:
• a detection apparatus configured to detect a position of a user's eye;
• and
• a three-dimensional display apparatus that includes:
• a display surface that is configured from a curved surface that does not curve along a first direction but curves within a plane orthogonal to the first direction, the display surface including a plurality of subpixels arranged in a grid pattern along the first direction and a direction that is orthogonal to the first direction within the display surface;
• an optical element that is arranged along the curved surface and defines a beam direction of image light emitted from each of the plurality of subpixels for each of a plurality of strip-shaped regions extending in a certain direction within a plane that is along the curved surface;
• and
• a controller configured to acquire the position of the user's eye and change an image displayed by each of the plurality of subpixels based on the display surface, the optical element, and the position of the user's eye.
