Abstract
A display apparatus providing an expanded eye box including: an image forming apparatus including a plurality of sub-areas respectively forming a plurality of different images; and a plurality of holographic optical elements corresponding to the plurality of sub-areas one-to-one, and collimating images emitted from the plurality of sub-areas to parallel beams having different emission directions, respectively.
Claims20
A display apparatus comprising:
- an image forming apparatus including a plurality of sub-areas respectively configured to form a plurality of images by using light;
- and
- a plurality of holographic optical elements corresponding to the plurality of sub-areas one-to-one, each of the plurality of holographic optical elements configured to collimate light emitted from the plurality of sub-areas corresponding to the plurality of images into respective parallel beams,
- wherein each of the respective parallel beams are emitted in different directions such that at least two of the respective parallel beams overlap on a user's pupil to form an eye box.
1 more element
A display apparatus comprising:
- an image forming apparatus configured to output a plurality of images;
- a first holographic optical element configured collimate first light corresponding to a first image, among the plurality of images emitted from the image forming apparatus, into first parallel beams;
- and
- a second holographic optical element configured collimate second light corresponding to a second image, among the plurality of images emitted from the image forming apparatus, into second parallel beams,
- wherein the first parallel beams and the second parallel beams overlap on a user's pupil to form an eye box.
2 more elements
A display method comprising:
- outputting, by an image forming apparatus, a plurality of images;
- collimating, by a first holographic optical element, first light corresponding to a first image, among the plurality of images emitted from the image forming apparatus, into first parallel beams;
- and
- collimating, by a second holographic optical element, second light corresponding to a second image, among the plurality of images emitted from the image forming apparatus, into second parallel beams,
- wherein the first parallel beams and the second parallel beams overlap on a user's pupil to form an eye box.
