1. A display system, comprising
an emissive body, emitting light over a complete surface as part of a display system, said emissive body including a first transparent conductive coating over a light emitting substrate, and including a transparent substrate, having first and second surfaces, said first surface coupled to said first transparent conductive coating, and said second surface of said transparent substrate including a surface formed with plural light channeling structures thereon.
2. The display system as in claim 1 , wherein said emissive body emits light from both front and back.
3. The display system as in claim 1 , wherein said light channeling structures comprise an array of prisms.
4. The display system as in claim 1 , wherein said light channeling structures comprise an array of micro-lenses.
5. The display system as in claim 1 , further comprising a spatial light modulator, located to receive the light from said second surface of said transparent substrate.
6. The display system as in claim 5 , wherein said spatial light modulator is liquid crystal, forming a liquid crystal display.
7. The display system as in claim 6 , wherein the display system is a television.
8. This display system as in claim 6 wherein the display system is in a portable computer.
9. The display system as in claim 8 , wherein said portable computer is one of a tablet, cell phone, or PDA.
10. The display system as in claim 6 wherein said spatial light modulator is composed of elements that are one of: TFT, VA, IPS, IGZO.
11. A method of forming light, comprising
emitting light over a complete surface as part of a display system, using a device with an emissive body including a first transparent conductive coating over a light emitting material having first and second surfaces; and
channeling the emitted light using a shaped surface on a transparent substrate attached to said first transparent coating, where the shaped surface includes plural light channeling structures thereon.
12. The method as in claim 11 , wherein said emitting light comprises emitting light from both front and back of the surface.
13. The method as in claim 11 , wherein said light channeling structures comprise an array of prisms.
14. The method as in claim 11 , wherein said light channeling structures comprise an array of micro-lenses.
15. The method as in claim 11 , further comprising creating a display using a spatial light modulator, located to receive the light from said second surface of said transparent substrate.
16. The method as in claim 15 , wherein said spatial light modulator is liquid crystal, forming a liquid crystal display.
17. The method as in claim 15 , wherein the display is in a television.
18. This method as in claim 15 wherein the display is in a portable computer.
19. The method as in claim 18 , wherein said portable computer is one of a tablet, cell phone, or PDA.
20. The method as in claim 16 wherein said spatial light modulator is composed of elements that are one of: TFT, VA, IPS, IGZO.
21. A display system, comprising
an emissive body, emitting light over a complete surface as part of a display system, said emissive body including a light emitting material, a first transparent conductive coating over light emitting material, a transparent substrate, having a first surface attached to said first conductive coating and a second surface formed with plural light channeling structures thereon; and
a spatial light modulator, adjacent said emissive body and receiving light from said light channeling structures, over a surface of the spatial light modulator.
22. The display system as in claim 21 , wherein said emissive body emits light from both front and back.
23. The display system as in claim 21 , wherein said light channeling structures comprise an array of prisms.
