Altering surface of display screen from matt to optically smooth
A matt surface ( 7 ) of a display screen ( 2 ) is converted to a non-diffuse optically smooth surface ( 11 ). The matt surface may be a diffusive surface ( 7 ) formed on a birefringent film ( 6 ) of an LCD screen ( 2 ). The display screen ( 2 ) is the front screen of a multilevel three dimensional display comprising layered screens ( 2, 3 ). The conversion from matt to non-diffuse and optically smooth surface reduces the blurring of displayed images.
1. A method of altering a surface of a multi focal-plane display said method comprising:
removing an existing material comprising a matte surface from said multi focal-plane display; and and
replacing said existing material comprising said matte surface with a material comprising a non-diffuse surface.
2. The method of claim 1 , wherein at least one display screen of said multi focal-plane display comprises an LCD.
3. The method of claim 1 , wherein said material comprising said non-diffuse surface comprises a polarizer film.
4. The method of claim 3 , wherein said polarizer film is formed from a protective transparent layer encapsulating a polarizing layer.
5. The method of claim 1 , wherein said multi focal-plane display comprises a first display screen and a second display screen, and wherein said first and second display screens overlap.
6. The method of claim 5 , wherein said material comprising said matte surface is removed from said second display screen and replaced with said material comprising said non-diffuse surface.
7. The method of claim 6 , wherein a graphical object displayed on said first display screen is viewable through said second display screen, and wherein said graphical object has greater clarity when viewed through said material comprising said non-diffuse surface than when viewed through said material comprising said matte surface.
8. The method of claim 5 , wherein said second display screen is interchangeable with a third display screen, wherein said second display screen is coupled with said material comprising said matte surface and said third display screen is coupled with said material comprising said non-diffuse surface.
9. The method of claim 8 , wherein a graphical object displayed on said first display screen is viewable through at least one of said second and third display screens, and wherein said graphical object has greater clarity when viewed through said material comprising said non-diffuse surface than when, viewed through said material comprising said matte surface.
10. The method of claim 1 , wherein said non-diffuse surface is optically smooth.
