Abstract

A display device includes a front portion, a rear portion, a halo, and sides extending between the front portion and the rear portion. The front portion, the rear portion, and the sides form an enclosure. The halo includes a rim and an internal structure. The rim is positioned between the front portion and the rear portion. The internal structure is at least partially within the enclosure and includes a sweep portion and a receiving post. The receiving post and the sweep portion are configured to receive light emitted by one or more light emitting devices and at least one of guide, direct, diffuse, focus, and scatter light emitted by the one or more light emitting devices out of the display device.

Claims

1. A display device comprising:

a front portion and a rear portion;

sides extending between the front portion and the rear portion, wherein the sides, the front portion, and the rear portion form an enclosure; and

a halo comprising a rim and an internal structure, wherein the rim is positioned between the front portion and the rear portion and the internal structure of the halo is at least partially within the enclosure and comprises a sweep portion and a receiving post;

wherein the receiving post and the sweep portion are configured to receive light emitted by one or more light emitting devices and at least one of guide, direct, diffuse, focus, and scatter light emitted by the one or more light emitting devices out of the display device.

2. The display device of claim 1, wherein the halo is configured to at least one of guide, direct, diffuse, focus, and scatter the light emitted by the one or more light emitting devices along or outwards from at least one of the sides of the display device through the rim.

3. The display device of claim 1, further comprising a controller configured to adjust at least one of a brightness and a color of at least one of the one or more light emitting devices.

4. The display device of claim 1, wherein the sweep portion is generally S-shaped and protrudes at a first end from the rim.

5. The display device of claim 4, wherein the receiving post extends from a second end of the sweep portion.

6. The display device of claim 5, wherein a width of the sweep portion varies along a path of the sweep portion.

7. The display device of claim 6, wherein the width of the sweep portion decreases from the first end of the sweep portion to the second end of the sweep portion, and wherein a final width of the sweep portion is substantially equal to a width of the receiving post.

8. The display device of claim 1, wherein the halo comprises at least one of a translucent and a transparent material and is configured to allow light to pass through.

9. The display device of claim 1, wherein the internal structure is positioned within the enclosure formed by the sides, the rear portion, and the front portion, and wherein the rim is positioned between the front portion and the rear portion.

10. The display device of claim 1, wherein the front portion comprises a display device configured to display information.

11. The display device of claim 1, wherein the halo is configured to direct light outwards from the display device such that the light is viewable from a side of the display device.

12-20. -20. (canceled)

21. A display device comprising:

a front portion and a rear portion;

sides extending between the front portion and the rear portion, wherein the sides, the front portion, and the rear portion form an enclosure; and

a halo comprising a rim and an internal structure, wherein the rim is positioned between the front portion and the rear portion and the internal structure of the halo is at least partially within the enclosure and comprises a sweep portion and a receiving post;

wherein the halo tracks a gradient color of a status bar for consistency with the rest of the display;

wherein the receiving post and the sweep portion are configured to receive light emitted by one or more light emitting devices and at least one of guide, direct, diffuse, focus, and scatter light emitted by the one or more light emitting devices out of the display device.

22. A display device comprising:

a front portion and a rear portion;

sides extending between the front portion and the rear portion, wherein the sides, the front portion, and the rear portion form an enclosure; and

a halo comprising a rim and an internal structure, wherein the rim is positioned between the front portion and the rear portion and the internal structure of the halo is at least partially within the enclosure;

wherein the internal structure is configured to receive light emitted by one or more light emitting devices and at least one of guide, direct, diffuse, focus, or scatter light emitted by the one or more light emitting devices out of the display device.

23. A display device comprising:

a front portion and a rear portion;

sides extending between the front portion and the rear portion, wherein the sides, the front portion, and the rear portion form an enclosure; and

a hale diffusion element comprising a rim, wherein the rim is positioned between the front portion and the rear portion and the diffusion element extends at least partially within the enclosure;

wherein the halo diffusion element is configured to diffuse light emitted by a light emitting device within the enclosure outwards between the front portion and the rear portion to facilitate an off-axis viewing angle of light emitted by the light emitting device.

24. The display device of claim 23, wherein the halo diffusion element is configured to at least one of guide, direct, focus, and scatter the light emitted by the light emitting device along or outwards from at least one of the sides of the display device through the rim.

25. The display device of claim 23, further comprising a controller configured to adjust at least one of a brightness and a color of at least one of the light emitting device.

26. The display device of claim 23, wherein the halo diffusion element comprises a sweep portion, the sweep portion being generally S-shaped and protruding at a first end from the rim.

27. The display device of claim 26, wherein the receiving post extends from a second end of the sweep portion.

28. The display device of claim 27, wherein a width of the sweep portion varies along a path of the sweep portion.

29. The display device of claim 28, wherein the width of the sweep portion decreases from the first end of the sweep portion to the second end of the sweep portion, and wherein a final width of the sweep portion is substantially equal to a width of the receiving post.

30. The display device of claim 23, wherein the halo diffusion element comprises at least one of a translucent and a transparent material and is configured to allow light to pass through. wherein the internal structure is positioned within the enclosure formed by the sides, the rear portion, and the front portion, and wherein the rim is positioned between the front portion and the rear portion, and wherein the front portion comprises a display device configured to display information.
