Abstract

Improvements to computer displays particular displays for tablet PCs to: increase their clarity, contrast ratio and viewability in high ambient light conditions such as sunlight; cooler operation; and more rugged structure.

Claims

1. A computer system with a combined output and input display comprising:

a computer system which generates a video output signal;

a display which converts the video output signal into a visual for perceptible by a human user;

a digitizer mounted adjacent to the display which detects the user input in relation to the display output and converts the input into a signal processable by the computer system; and

a protective sheet affixed to the display adhesively so that there is no air gap between the protective sheet and the display.

2. The computer system with input/output display of claim 1 wherein the protective sheet has an antireflective coating

3. The computer system with input/output display of claim 1 wherein the protective sheet has an interference coating

4. The computer system with input/output display of claim 3 wherein the interference coating is optimized for the primary colors generated by said display.

5. The computer system with input/output display of claim 3 wherein the interference coating is optimized for the primary colors detectible by the cones in the retna of the human eye.

6. The computer system with input/output display of claim 1 wherein the protective sheet has a hydrophobic coating

7. The computer system with input/output display of claim 6 wherein the protective sheet is textured to provide resistance for stylus input.

8. The computer system with input/output display of claim 1 wherein the protective sheet has an antireflective coating and a an anit-smudge coating.

9. The computer system with input/output display of claim 8 wherein the protective sheet is textured to provide resistance for stylus input.

10. The computer system with input/output display of claim 1 wherein the protective sheet has a coating that provides broadband light transmission properties and high hydrophobicity properties.

11. The computer system with input/output display of claim 10 wherein the protective sheet is textured to provide resistance for stylus input.

12. A combined input and output display input/output display comprising:

a computer system which generates a video output signal;

a display which converts the video output signal into a visual for perceptible by a human user wherein the display as a continuous set of functional protective layers with no air gaps between the layers;

a digitizer mounted adjacent to the display which detects the user input in relation to the display output and converts the input into a signal processable by the computer system; and

a protective sheet affixed to the display adhesively so that there is no air gap between the protective sheet and the display.

13. The input/output display of claim 12 wherein the functional layers include a hydrophobicity layer.

14. The input/output display of claim 12 wherein the functional layers include an antireflective layer.

15. The input/output display of claim 12 wherein the functional layers include a hydrophobicity and antireflective layer.

16. The input/output display of claim 12 wherein the outer surface is textured to provide resistance for stylus input.

17. A combined input and output display input/output display comprising:

a computer system which generates a video output signal;

a display which converts the video output signal into a visual for perceptible by a human user wherein the display as a continuous set of functional protective layers including a combined antireflective anti-smudge layer with no air gaps between the layers;

a digitizer mounted adjacent to the display which detects the user input in relation to the display output and converts the input into a signal processable by the computer system; and

a protective sheet affixed to the display adhesively so that there is no air gap between the protective sheet and the display.

18. A combined input and output display input/output display of claim 17 wherein the protective layers are mounted to the display with an index of refraction matching adhesive layer.

19. A combined input and output display input/output display of claim 17 wherein a protective bezel is mounted on top of the outer edges of the protective layers.
