Spacer for an assembly of a backlight of a display
The present disclosure relates to a spacer for an assembly of a backlight of a display. The disclosure additionally relates to an assembly for a backlight of a display having such a spacer, and to a display having a backlight having such an assembly. The spacer comprises at least one crosspiece. The crosspiece in this case has attachment surfaces for attachment of a first light guide and a second light guide and a receptacle for a sheet stack.
1. An assembly for a backlight of a display, the assembly comprising:
a spacer, comprising:
at least one crosspiece with attachment surfaces;
a first light guide;
a second light guide, wherein the first light guide and the second light guide are attached to attachment surfaces of the spacer by optically clear adhesive sheets; and
a sheet stack.
2. The assembly as claimed in claim 1 , wherein the spacer, the first light guide, and the second light guide have substantially the same coefficient of expansion.
3. The assembly as claimed in claim 1 , wherein the spacer comprising the at least one crosspiece with attachment surfaces is for attachment of the first light guide and the second light guide and a receptable for the sheet stack.
4. The assembly as claimed in claim 3 , wherein the spacer further comprises alignment elements for aligning the first light guide, the second light guide, or the sheet stack.
5. The assembly as claimed in claim 3 , wherein the receptable for the sheet stack is formed by a cutout in the at least one crosspiece.
6. The assembly as claimed in claim 3 , wherein the spacer is designed to optically screen off the first light guide and the second light guide from one another.
7. The assembly as claimed in claim 3 , wherein the spacer is designed for use as a positioning element and a holding element in the display.
8. A display, comprising:
a backlight, wherein the backlight further comprises an assembly comprising:
at least one crosspiece with attachment surfaces;
a first light guide;
a second light guide, wherein the first light guide and the second light guide are attached to attachment surfaces of the spacer by optically clear adhesive sheets; and
a sheet stack.
9. The display as claimed in claim 8 , wherein the backlight further comprises a printed circuit board with two or more light sources.
10. An assembly for a backlight of a display, the assembly comprising:
a spacer, comprising:
at least one crosspiece with attachment surfaces;
a first light guide;
a second light guide, wherein the spacer, the first light guide, and the second light guide have substantially the same coefficient of expansion; and
a sheet stack.
11. The assembly as claimed in claim 10 , wherein the spacer comprising the at least one crosspiece with attachment surfaces is for attachment of the first light guide and the second light guide and a receptable for the sheet stack.
12. The assembly as claimed in claim 11 , wherein the spacer further comprises alignment elements for aligning the first light guide, the second light guide, or the sheet stack.
13. The assembly as claimed in claim 11 , wherein the receptable for the sheet stack is formed by a cutout in the at least one crosspiece.
14. The assembly as claimed in claim 11 , wherein the spacer is designed to optically screen off the first light guide and the second light guide from one another.
15. The assembly as claimed in claim 11 , wherein the spacer is designed for use as a positioning element and a holding element in the display.
