Abstract
An image display apparatus includes a light source, a display device, an at least one illumination prism, and an at least one eyepiece optic. The light source emits illumination light. The display device modulates the illumination light and emits the modulated light as image light. The illumination light emitted from the light source is incident on the illumination prism. The at least one eyepiece optic transmits the image light emitted from the display device.
Claims36
An image display apparatus comprising:
- a light source that emits illumination light;
- a display device that modulates the illumination light and emits the modulated light as image light;
- at least one illumination optic that transmits the illumination light emitted from the light source to the display device and that has an optical surface having positive optical power;
- and
- at least one eyepiece optic that transmits the image light from the display device and that has an eyepiece surface transmitting the transmitted image light,
- wherein the at least one illumination optic focuses an image of the light source on one of the eyepiece surface and the vicinity of the eyepiece surface in a first plane, the first plane comprising a central ray of the image light emitted from the display device.

- a display device that modulates the illumination light and transmits the modulated light as image light;
- at least one illumination optic that transmits the illumination light emitted from the light source to the display device and that has positive optical power;
- and
- at least one eyepiece optic that transmits the image light from the display device and that has an eyepiece surface transmitting the transmitted image light to outside of the at least one eyepiece optic,
- wherein the at least one illumination optic:
- focuses the transmitted image light on the outside of the at least one eyepiece optic in a first plane, the first plane comprising a central ray of the image light transmitted from the display device, and
- focuses the transmitted image light between the display device and the eyepiece surface in a second plane, the second plane different from the first plane and the second plane comprising the central ray.

An image display apparatus comprising:
- a first light source that emits illumination light;
- a display device that modulates the illumination light and transmits the modulated light as image light;
- at least one illumination optic that transmits the illumination light emitted from the first light source to the display device and that has positive optical power;
- and
- at least one eyepiece optic that transmits the image light from the display device and that has an eyepiece surface transmitting the transmitted image light,
- wherein a sagittal focal position which is a focal position of the at least one illumination optic in a sagittal plane with the light source as an object point is located closer to the display device than a meridional focal position which is a focal position in a meridional plane.
