Abstract
A three-dimensional (3D) image display apparatus is provided. The apparatus includes a plurality of light sources; a spatial light modulator configured to modulate light from the plurality of light sources according to 3D image information; and a focusing optical system configured to focus an image formed by the spatial light modulator onto a focal plane. The plurality of light sources may be arranged such that multiple focal points, respectively corresponding to the plurality of light sources, are formed on the focal plane near a pupil of a user.
Claims17
A three-dimensional (3D) image display apparatus comprising:
- a plurality of light sources arranged to form a respective plurality of focal points on a focal plane, wherein each of the plurality of light sources comprises a light emitting element providing light of a red wavelength band, a light emitting element providing light of a green wavelength band, and a light emitting element providing light of a blue wavelength band;
- a spatial light modulator configured to modulate light from the plurality of light sources according to 3D image information;
- a focusing optical system configured to focus an image formed by the spatial light modulator on the focal plane;
- a processor configured to:
- control a turn-on operation and a turn-off operation of the plurality of light sources sequentially to alternately turn on and off the plurality of light sources, and form the respective plurality of focal points on the focal plane;
- and
- select a driving light source, of the plurality of light sources, based on a pupil position of an observer and a position of a focal point of the driving light source, such that the position of the focal point of the driving light source is closest to the pupil position of the observer among positions of the plurality of focal points.
A display system comprising:
- a 3D display device comprising;
- a plurality of light sources arranged to form a respective plurality of focal points on a focal plane, wherein each of the plurality of light sources comprises a light emitting element providing light of a red wavelength band, a light emitting element providing light of a green wavelength band, and a light emitting element providing light of a blue wavelength band;
- a spatial light modulator configured to modulate light from the plurality of light sources according to 3D image information;
- and
- a focusing optical system configured to focus an image formed by the spatial light modulator on the focal plane;
- and
- a smart device including a processor configured to:
- control a turn-on operation and a turn-off operation of the plurality of light sources sequentially to alternately turn on and off the plurality of light sources, and form the respective plurality of focal points on the focal plane;
- and
- select a driving light source, of the plurality of light sources, based on a pupil position of an observer and a position of a focal point of the driving light source, such that the position of the focal point of the driving light source is closest to the pupil position of the observer among positions of the plurality of focal points.
