Abstract

A display assembly includes a display member and backlight member. The backlight member has a light source and is bonded directly to the display member. The backlight member can be bonded directly to a display area of the display member, and an optically transparent adhesive can be used to bond a first surface of the backlight member to a first surface of the display member.

Claims

1. A display assembly, comprising:

a display member, the display member being configured to be operatively coupled to a processor and configured to modulate light to produce an image; and

a plurality of backlight members, each backlight member being separate from each other backlight member, each backlight member having a plurality of embedded light sources including at least one white light source and at least one color light source, each backlight member being configured to supply the light that is modulated by the display member, an entire surface of each backlight member being bonded directly to the display member.

2. The display assembly of claim 1, wherein the display member includes an inner surface and an outer surface opposite the inner surface, each backlight member is bonded directly to the inner surface of the display member.

3. The display assembly of claim 1, wherein the display member has a display area, each backlight member being bonded directly to the display area of the display member.

4. The display assembly of claim 1, wherein each backlight member is bonded directly to the display member via an adhesive.

5. The display assembly of claim 1, wherein each backlight member is bonded directly to the display member via an optically transparent adhesive.

6. The display assembly of claim 1, each backlight member is a separate monolithic block having the plurality of embedded light sources, and each separate monolithic block being bonded directly to the display member.

7. The display assembly of claim 1, further comprising:

a housing, the housing being coupled to each backlight member such that each backlight member is disposed between the display member and the housing.

8. The display assembly of claim 1, further comprising:

a housing member, the housing being bonded directly to each backlight member via an adhesive such that each backlight member is disposed between the display member and the housing member.

9. The display assembly of claim 1, further comprising:

a frame configured to receive and support the backlight members that are bonded to the display member, the frame including tapered portions configured to couple with tapered portions of the backlight members.

10. The display assembly of claim 1, wherein the display member is a liquid crystal display.

11. The display assembly of claim 1, wherein each backlight member is monolithic, and each backlight member includes angled side surfaces configured to interconnect with neighboring backlight members.

12. A display assembly, comprising:

a display member, the display member having a display area;

a first backlight member defined as a first monolithic block having a first plurality of light sources including at least one white light source and at least one color light source, and being configured to supply first light that is modulated by the display member, the first backlight member being bonded directly to a surface of the display member within the display area of the display member; and

a second backlight member defined as a second monolithic block having a second plurality of light sources including at least one white light source and at least one color light source, and being configured to supply second light that is modulated by the display member, the second backlight member being bonded directly to the surface of the display member within the display area of the display member.

13. The display assembly of claim 12, wherein the first backlight member includes a first surface and a second surface opposite the first surface, the display member includes an inner surface and an outer surface opposite the inner surface, and the entire outer surface of the backlight member is coupled to the inner surface of the display member.

14. The display assembly of claim 12, further comprising:

a housing member coupled to the plurality of light sources such that the plurality of light sources are disposed between the housing and the display.

23. The display assembly of claim 12, further comprising:

one or more additional backlight members with each additional backlight member having multiple light sources including at least one white light source and at least one color light source, and being configured to supply light that is modulated by the display member, the one or more additional backlight members being bonded directly to the surface of the display member within the display area of the display member.

24. The display assembly of claim 12, wherein each backlight member is separate from each other backlight member, and each backlight member is bonded directly to the surface of the display member within the display area of the display member using an adhesive.

25. The display assembly of claim 12, wherein each backlight member is a separate monolithic block, and each separate monolithic block is bonded directly to the surface of the display member within the display area of the display member.

26. The display assembly of claim 12, further comprising:

a frame configured to receive and support the backlight members that are bonded to the display member, the frame including tapered portions configured to couple with tapered portions of the backlight members.

27. The display assembly of claim 12, wherein each backlight member includes angled side surfaces configured to interconnect with neighboring backlight members.

15. A method of assembling a display, comprising:

providing a display member;

providing a plurality of individual backlight members, each individual backlight member being a separate monolithic block from each other individual backlight member, each individual backlight member having multiple embedded light sources including at least one white light source and at least one color light source; and

directly bonding an entire first surface of each individual backlight member to a first surface of the display member.

16. The method of claim 15, wherein the directly bonding includes applying an adhesive to at least one of the first surface of the display member and the first surface of each individual backlight member.

17. The method of claim 15, wherein the directly bonding includes applying an adhesive to at least one of the first surface of the display member and the first surface of each individual backlight member and applying a pressure to at least one of the display and each individual backlight member.

18. The method of claim 15, wherein the directly bonding includes applying an adhesive to at least one of the first surface of the display member and the first surface of each individual backlight member and exposing the adhesive to ultraviolet radiation to cure the adhesive.

19. The method of claim 15, wherein the directly bonding includes directly bonding the first surface of each individual backlight member to a portion of the first surface of the display member, the portion of the first surface of the display member being within a display area of the display member.

20. The method of claim 15, wherein directly bonding includes directly bonding each separate monolithic block to the first surface of the display member using an adhesive.

21. The method of claim 15, further comprising:

directly bonding a housing member to each backlight member such that each backlight member is disposed between the housing and the display member.

22. The method of claim 15, wherein the display member is a liquid crystal display and each light source is a light emitting diode.

28. The method of claim 15, further comprising:

providing a frame configured to receive and support the backlight members that are bonded to the display member, the frame including tapered portions configured to couple with tapered portions of the backlight members.

29. The method of claim 15, wherein each backlight member includes angled side surfaces configured to interconnect with neighboring backlight members.
