Abstract

An apparatus, system, and/or method that integrates excitable light emitting materials (that are transparent) into any surface to display an image. Light emitting materials may be integrated into uneven, irregular, and/or random surfaces, displays may be formed on objects that are not practical for flat panel displays (e.g. steering wheels). Light emitting materials may be integrated onto or into the surface of a flat panel display that is responsive to excitation light of a laser pointer, thus allowing flat panel displays to be more effectively used in presentation applications. Since the light emitting materials are transparent, application of light emitting materials into objects does not obstruct the view of the objects when the light emitting materials are not being used to display images.

Claims

1. A system comprising:

a light source;

a physical medium; and

light emitting material integrated into at least a portion of the surface of the physical medium,

wherein the light emitting material is configured to emit visible light in response to absorption of at least one of ultraviolet or lower wavelength visible light from the light source,

wherein the light emitting material comprises a plurality of light emitting particles, and

wherein each of the plurality of light emitting particles has a diameter less than about 500 nanometers, and

the surface of the physical medium is an object on which an emissive image can be displayed by the emitted visible light in response to the light source.

2. The system of claim 1, wherein the light source is a laser pointer and the surface is at least a portion of a display device.

3. The system of claim 2, wherein:

the display device outputs an image which is independent of the visible light emitted in response to absorption of light from the laser pointer; and

a user of the laser pointer at least one of annotates, supplements, and highlights the content output from the display device.

4. The system of claim 2, wherein the display device is at least one of:

a flat panel display;

an LCD display;

an OLED display;

a LED display;

a plasma display;

a quantum dot display;

a CRT display;

a television;

a monitor; and

a heads up display.

5. The system of claim 1, wherein:

the surface is at least one of an uneven surface, an irregular surface, or a random surface; and

an image can be displayed on the at least one of the uneven surface, the irregular surface, or the random surface by emitting visible light in response to absorption of light from the light source.

6. The system of claim 5, wherein the at least one of the uneven surface, the irregular surface, or the random surface comprises a surface of a vehicle.

7. The system of claim 6, wherein the surface of the vehicle comprises at least one of:

a gage cluster of a vehicle;

a transparent cover separated from instruments of the vehicle;

a steering wheel;

a mirror;

a flat panel display;

instruments;

interior surfaces;

exterior body panels; and

windows.

8. The system of claim 1, comprising a proximity sensor coupled to the light source to allow feedback from a user movement in relation to the visible light emitted in response to the absorption of light from the light source.

9. The system of claim 1, wherein the visible light emitted in response to absorption of light from the light source comprises a display of a graphical user interface.

10. The system of claim 1, wherein the light source is an ultraviolet projector.

11. The system of claim 1, wherein the light source is a visible light projector.

12. The system of claim 1, wherein the physical medium has at least one of no visible light transmittance characteristics or relatively low visible light transmittance characteristics.

13. The system of claim 12, wherein the physical medium is substantially dark.

14. The system of claim 12, wherein the physical medium is opaque.

15. The system of claim 1, wherein the physical medium has relatively low visible light absorption characteristics.

16. The system of claim 15, wherein the physical medium is substantially transparent.

17. The system of claim 15, wherein the physical medium is reflective.

18. The system of claim 1, wherein the light emitting material comprises at least one of the following fluorescent materials:

inorganic phosphor nanoparticles;

fluorescent quantum dots;

small molecules with organic chromophore;

organic dyes;

organic pigments;

organo-metallic molecules;

polymers;

or

oligomers.

19. The system of claim 1, wherein the light emitting material comprises:

a first material which emits a first visible color; and

a second material which emits a second visible color, which is different from the first visible color.

20. The apparatus of claim 19, wherein the light emitting material comprises a third material which emits a third visible color, which is different from the first visible color and the second visible color.
