Abstract

Disclosed herein are example edge-to-edge display devices and related methods. An example display device includes a display screen and a backlight including a light guide frame defining a cavity therein. The example display device includes an integrated circuit coupled to the display screen. The example display device includes a flexible printed circuit in communication with the integrated circuit and including an electrical component coupled thereto. The electrical component is at least partially disposed in the cavity of the light guide frame.

First claim

What is claimed is:

1. An electronic display device comprising:
a housing;
a display screen supported by the housing;
a panel carried by the housing; and
a backlight including:
a first light source coupled to the panel;
a second light source coupled to the panel, the second light source spaced apart from the first light source; and
a first spacer disposed between the first light source and the second light source, the first spacer including a reflective coating.

2. The electronic display device of claim 1 , further including:
a third light source coupled to the panel, the third light source spaced apart from the second light source; and
a second spacer disposed between the second light source and the third light source, the second spacer including the reflective coating.

3. The electronic display device of claim 1 , wherein the panel and the display screen define a gap therebetween, the reflective coating of the first spacer to diffuse light emitted by one or more of the first light source or the second light source over the gap.

4. The electronic display device of claim 1 , wherein the first light source is disposed proximate to an edge of the display screen, at least a portion of light emitted by the first light source to be distributed to the edge of the display screen.

5. The electronic display device of claim 1 , wherein the first light source is a single chip light emitting diode and the second light source is a single chip light emitting diode.

6. The electronic display device of claim 1 , wherein the first light source is a two-chip light emitting diode and the second light source is a two-chip light emitting diode.

7. The electronic display device of claim 1 , wherein the reflective coating includes paint.

8. The electronic display device of claim 1 , wherein the first spacer includes silicon dioxide.

9. An apparatus comprising:
a display screen;
a panel, a gap defined between the panel and the display screen;
a first light source coupled to the panel;
a second light source coupled to the panel, the second light source spaced apart from the first light source, light emitted by one or more of the first light source and the second light source to be emitted over the gap; and
a protrusion coupled to the panel, the protrusion disposed between the first light source and the second light source, the protrusion including a reflective coating.

10. The apparatus of claim 9 , wherein the protrusion is a first protrusion and further including a third light source coupled to the panel, the third light source spaced apart from the first light source and the second light source, a second protrusion disposed between the second light source and the third light source, the second protrusion including the reflective coating.

11. The apparatus of claim 9 , wherein the first light source is a single chip light emitting diode and the second light source is a single chip light emitting diode.

12. The apparatus of claim 9 , wherein the first light source is a two-chip light emitting diode and the second light source is a two-chip light emitting diode.

13. The apparatus of claim 9 , wherein the protrusion includes silicon dioxide.

14. A display comprising:
a display screen; and
a backlight, the backlight including:
a first light source;
a second light source; and
means for diffusing light, the means for diffusing disposed between the first light source and the second light source.

15. The display of claim 14 , wherein the means for diffusing includes a photo spacer.

16. The display of claim 15 , wherein the means for diffusing includes a protrusion having a reflective coating, the protrusion coupled to a panel of the backlight.

17. The display of claim 14 , wherein the first light source and the second light source are coupled to a panel, a gap defined between the panel and the display screen, the means for diffusing to diffuse light emitted by one or more of the first light source or the second light source over the gap.

18. The display of claim 14 , wherein the backlight further includes a third light source and the means for diffusing includes first means for diffusing disposed between the first light source and the second light source and second means for diffusing disposed between the second light source and the third light source.

19. The display of claim 14 , wherein the first light source is disposed proximate to an edge of the display screen, the means for diffusing to cause at least a portion of light emitted by the first light source to be distributed to the edge of the display screen.

20. The display of claim 14 , wherein the first light source includes a light emitting diode having one or more chips.
