Abstract

A display structure for an information handling system, including a top surface layer; a first nanoporous layer; a first polarizer layer; a thin-film-transistor (TFT) layer; a second polarizer layer; and a back light layer, wherein the first nanoporous layer is positioned between the top surface layer and the first polarizer layer, and wherein the first nanoporous layer has an index of refraction less than the index of refraction of the top surface layer to reduce specular reflection of the display structure.

Claims (34)

1. A display structure for an information handling system, including:

a top surface layer;

a first nanoporous layer;

a first polarizer layer;

a second nanoporous layer;

a thin-film-transistor (TFT) layer;

a second polarizer layer; and

a back light layer,

wherein the first nanoporous layer is positioned between the top surface layer and the first polarizer layer, and the second nanoporous layer is positioned between the first polarizer layer and the TFT layer, and

wherein the first nanoporous layer has an index of refraction less than an index of refraction of the top surface layer to reduce specular reflection of the display structure, and the second nanoporous layer has an index of refraction less than an index of refraction of the TFT layer to reduce specular reflection of the display structure.

2. The display structure of claim 1 , further comprising a mesoporous layer positioned on the top surface layer.

3. The display structure of claim 1 , further comprising a mesoporous layer positioned between the first nanoporous layer and the first polarizer layer.

4. The display structure of claim 1 , wherein the top surface layer is glass.

5. The display structure of claim 1 , wherein the top surface layer is plastic.

6. The display structure of claim 1 , wherein the index of refraction of the first nanoporous layer is less than 1.5.

7. The display structure of claim 1 , wherein the index of refraction of the first nanoporous layer is approximately 1.3.

8. The display structure of claim 1 , wherein the index of refraction of the first nanoporous layer is approximately 1.13.

9. The display structure of claim 1 , wherein the specular reflection of the display structure is approximately 1.6 percent of incident light upon the display structure.

10. The display structure of claim 1 , wherein the display structure is a liquid crystal display (LCD) display structure.

11. A display structure for an information handling system, including:

a top surface layer;

a first nanoporous layer;

a polarizer layer;

a second nanoporous layer; and

an organic light emitting diode (OLED) film layer,

wherein the first nanoporous layer is positioned between the top surface layer and the polarizer layer, wherein the second nanoporous layer is positioned between the polarizer layer and the OLED film layer, and

wherein the first nanoporous layer has an index of refraction less than an index of refraction of the top surface layer to reduce specular reflection of the display structure, and wherein the second nanoporous layer has an index of refraction less than an index of refraction of the OLED film layer to reduce specular reflection of the display structure.

12. The display structure of claim 11 , further comprising a mesoporous layer positioned on the top surface layer.

13. The display structure of claim 11 , wherein the top surface layer is glass.

14. The display structure of claim 11 , wherein the top surface layer is plastic.

15. The display structure of claim 11 , wherein the index of refraction of the nanoporous layer is less than 1.5.

16. The display structure of claim 11 , wherein the index of refraction of the nanoporous layer is approximately 1.3.

17. The display structure of claim 11 , wherein the index of refraction of the nanoporous layer is approximately 1.13.

18. The display structure of claim 11 , wherein the display structure is an OLED display structure.
