Abstract
Official abstract text for this publication.
A head-mounted display includes a left-eye display panel that displays a left-eye image, a left-eye optical system that has an angle of view from 45 to 55 degrees and forms a virtual image of the left-eye image, a right-eye display panel that displays a right-eye image, a right-eye optical system that has an angle of view from 45 to 55 degrees and forms a virtual image of the right-eye image, and a display control unit that controls the screen display of the left-eye display panel and the right-eye display panel.
First claim
Opening claim text (preview).
What is claimed is: 1. A head-mounted display, comprising: a left-eye display panel that displays a left-eye image; a left-eye optical system that has a horizontal angle of view from 45 to 55 degrees and forms a virtual image of the left-eye image; a right-eye display panel that displays a right-eye image; a right-eye optical system that has a horizontal angle of view from 45 to 55 degrees and forms a virtual image of the right-eye image; and a display control unit that controls the screen display of the left-eye display panel and the right-eye display panel. 2. The head-mounted display according to claim 1 , wherein the left-eye optical system forms a magnified virtual image of the left-eye image 10 meters or more away from a left eye, and the right-eye optical system forms a magnified virtual image of the right-eye image 10 meters or more away from a right eye. 3. The head-mounted display according to claim 1 , wherein each of the left-eye optical system and the right-eye optical system has even resolving power in a range of displacement with respect to corresponding eyeballs. 4. The head-mounted display according to claim 1 , wherein the left-eye display panel is disposed in a location displaced by a predetermined convergence horizontal offset from the position of a left eyeball, and the right-eye display panel is disposed in a location displaced by the predetermined convergence horizontal offset from the position of a right eyeball. 5. The head-mounted display according to claim 4 , wherein the predetermined convergence horizontal offset is set on the basis of a maximum interpupillary distance and the ratio of the size of the left-eye display panel and the right-eye display panel to the size of a surface on which the virtual image is focused. 6. The head-mounted display according to claim 5 , wherein the left-eye display panel is disposed in the location displaced by the predetermined convergence horizontal offset and the right-eye display panel is disposed in the location displaced by the predetermined convergence horizontal offset with a positional accuracy of several microns or less. 7. A head-mounted display, comprising: a left-eye display panel that displays a left-eye image; a left-eye optical system that has an angle of view from 45 to 55 degrees and forms a virtual image of the left-eye image; a right-eye display panel that displays a right-eye image; a right-eye optical system that has an angle of view from 45 to 55 degrees and forms a virtual image of the right-eye image; and a display control unit that controls the screen display of the left-eye display panel and the right-eye display panel, wherein the left-eye display panel is disposed in a location displaced by a predetermined convergence horizontal offset from the position of a left eyeball, and the right-eye display panel is disposed in a location displaced by the predetermined convergence horizontal offset from the position of a right eyeball, and wherein the predetermined convergence horizontal offset is set on the basis of a maximum interpupillary distance and the ratio of the size of the left-eye display panel and the right-eye display panel to the size of a surface on which the virtual image is focused. 8. The head-mounted display according to claim 7 , wherein the left-eye display panel is disposed in the location displaced by the predetermined convergence horizontal offset and the right-eye display panel is disposed in the location displaced by the predetermined convergence horizontal offset with a positional accuracy of several microns or less.
