Abstract

A display apparatus includes: a first light source configured to emit light visible from a first viewpoint; a second light source arranged in a row with the first light source in a first direction and configured to emit light visible from a second viewpoint; and a multi-view lens configured to refract the light emitted from the first light source toward the first viewpoint and to refract the light emitted from the second light source toward the second viewpoint, wherein each of the first light source and the second light source includes: a light emitter; and a slit cover covering a portion of the light emitter between the light emitter and the at least one multi-view lens, wherein the slit cover includes a light source slit having a first width and is configured to allow the light emitted from the light emitter to pass through the light source slit.

First claim

What is claimed is:

1 . A display apparatus comprising:
a first light source configured to emit light visible from a first viewpoint; a second light source arranged in a row with the first light source in a first direction and configured to emit light visible from a second viewpoint different from the first viewpoint; and at least one multi-view lens configured to refract the light emitted from the first light source to proceed toward the first viewpoint and to refract the light emitted from the second light source to proceed toward the second viewpoint, wherein each of the first light source and the second light source comprises:
a light emitter; and
a slit cover covering a portion of the light emitter between the light emitter and the at least one multi-view lens, wherein the slit cover comprises a light source slit having a first width and is configured to allow the light emitted from the light emitter to pass through the light source slit.

2 . The display apparatus of claim 1 , wherein the light source slit of the slit cover of each of the first light source and the second light source extends in a direction that is perpendicular to the first direction.

3 . The display apparatus of claim 1 , wherein the light source slit of the slit cover of each of the first light source and the second light source extends in a direction that is perpendicular to a direction in which the first viewpoint and the second viewpoint are arranged.

4 . The display apparatus of claim 1 , wherein the at least one multi-view lens comprises a plurality of multi-view lenses, and
wherein the light source slit of the slit cover of each of the first light source and the second light source extends in a direction that is perpendicular to a direction in which the plurality of multi-view lenses are arranged.

5 . The display apparatus of claim 1 , wherein the light emitter of each of the first light source and the second light source comprises:
a first light emitter configured to emit light of first color; a second light emitter configured to emit light of second color different from the first color; and a third light emitter configured to emit light of third color different from the first color and the second color, and wherein a direction in which the first light emitter, the second light emitter and the third light emitter are arranged is parallel with a direction in which the light source slit of the slit cover of each of the first light source and the second light source extends.

6 . The display apparatus of claim 1 , further comprising:
an entrance surface cover between the at least one multi-view lens and the first light source and the second light source, wherein the entrance surface cover comprises a lens slit having a second width, wherein the lens slit is configured to allow light having passed through the light source slit of one of the first light source or the second light source to pass through the entrance surface cover and enter the at least one multi-view lens.

7 . The display apparatus of claim 6 , wherein the second width is equal to or smaller than the first width.

8 . The display apparatus of claim 6 , wherein the entrance surface cover is on an entrance surface of the at least one multi-view lens, and
wherein the entrance surface of the at least one multi-view lens is adjacent to the first light source and the second light source.

9 . The display apparatus of claim 8 , wherein the entrance surface cover comprises a light absorber coated on the entrance surface of the at least one multi-view lens.

10 . The display apparatus of claim 6 , wherein the lens slit comprises:
a first lens slit configured to allow at least a portion of light having passed through the light source slit of the first light source to pass through the entrance surface cover; and a second lens slit arranged in parallel with the first lens slit and configured to allow at least a portion of light having passed through the light source slit of the second light source to pass through the entrance surface cover, wherein a center of the light emitter of the first light source, a center of the light source slit of the first light source and a center of the first lens slit are arranged in a line, and wherein a center of the light emitter of the second light source, a center of the light source slit of the second light source and a center of the second lens slit are arranged in a line.

11 . The display apparatus of claim 1 , wherein each of the first light source and the second light source further comprises a light source case accommodating the light emitter, and
wherein the slit cover of each of the first light source and the second light source is on a side of the light source case facing toward the at least one multi-view lens.

12 . The display apparatus of claim 11 , wherein each of the first light source and the second light source further comprises a transparent resin in the light source case enclosing the light emitter, and
wherein the slit cover of each of the first light source and the second light source covers a portion of the transparent resin on a side of the transparent resin facing toward the at least one multi-view lens.

13 . The display apparatus of claim 1 , wherein the slit cover of each of the first light source and the second light source comprises a light blocker around the light source slit and configured to block a portion of light emitted from the light emitter.

14 . The display apparatus of claim 13 , wherein the light blocker of each of the first light source and the second light source comprises a black coating layer configured to absorb a portion of light emitted from the light emitter.

15 . The display apparatus of claim 13 , wherein the light blocker of each of the first light source and the second light source comprises a reflective layer configured to reflect a portion of light emitted from the light emitter toward the light emitter.

16 . A display apparatus comprising:
a first light source configured to emit light visible from a first viewpoint; a second light source arranged in a row with the first light source in a first direction and configured to emit light visible from a second viewpoint different from the first viewpoint; and a multi-view lens comprising an entrance surface on a side of the multi-view lens facing the first light source and the second light source, the entrance surface comprising a first lens slit corresponding to the first light source and a second lens slit corresponding to the second light source, wherein the multi-view lens is configured to refract the light emitted from the first light source to proceed toward the first viewpoint and to refract the light emitted from the second light source to proceed toward the second viewpoint, and wherein each of the first light source and the second light source comprises:
a light emitter; and
a light source case accommodating the light emitter, the light source case comprising:
a slit cover on a side of the light source case adjacent to the entrance surface of the multi-view lens, the slit cover covering a portion of the light emitter between the light emitter and the multi-view lens, the slit cover comprising a light source slit having a first width; and
a plurality of walls surrounding the light emitter, wherein an inner surface of at least one of the plurality of walls comprises a slanted surface and an interior width of the light source case increases in a direction moving away from the light emitter and toward the slit cover.
