Abstract

A video display system includes a light source configured to generate light and a substrate having a plurality of pixels deposited on a first side of the substrate. Each of the pixels is formed from a plurality of photo-luminescent dyes, and the light source is configured to project light onto the first side of the substrate to illuminate at least a subset of the photo-luminescent dyes in a raster pattern to generate an image. In another embodiment omitting the substrate, the photo-luminescent dyes forming the pixels are deposited directly onto a screen.

First claim

What is claimed is:

1. A video display system comprising:
a screen having first and second sides;
a plurality of pixels deposited on the first side, each formed of a plurality of fluorescent dyes and including an infrared sub-pixel; and
a light source configured to project light onto the first side to illuminate at least a subset of the plurality of fluorescent dyes in a raster pattern to generate an image.

2. The video display system of claim 1 , wherein each pixel includes at least one of a red sub-pixel, a blue sub-pixel, and a green sub-pixel.

3. The video display system of claim 1 , wherein each pixel includes a repeating pattern of a red sub-pixel, a blue sub-pixel, a green sub-pixel, and an infrared sub-pixel.

4. The video display system of claim 1 , wherein the screen is substantially transparent to visible light.

5. The video display system of claim 1 , wherein the screen is substantially transparent to infrared light.

6. The video display system of claim 1 , wherein the light source includes a scanning laser configured to pulse on and off according to a duty cycle relative to each pixel position on the screen.

7. The video display system of claim 1 , wherein the fluorescent dyes are configured to emit light having a predetermined wavelength in response to receiving light from the light source.

8. The video display system of claim 7 , wherein the predetermined wavelength is independent of a frequency of the light generated by the light source.

9. The video display system of claim 1 , wherein the screen is a touch screen.

10. A motor vehicle video display system comprising:
a motor vehicle touch screen having first and second sides;
a plurality of pixels deposited on the first side, each formed of a plurality of fluorescent dyes and including an infrared sub-pixel; and
a light source configured to project light onto the first side to illuminate at least a subset of the plurality of dyes in a raster pattern to generate an image to be received by the touch screen.

11. The video display system of claim 10 , wherein the light source includes a scanning laser configured to pulse on and off according to a duty cycle relative to each pixel position on the screen.

12. The video display system of claim 10 , wherein each pixel includes at least one of a red sub-pixel, a blue sub-pixel, and a green sub-pixel.

13. The video display system of claim 10 , wherein each pixel includes a repeating pattern of a red sub-pixel, a blue sub-pixel, a green sub-pixel, and an infrared sub-pixel.

14. The video display system of claim 10 , wherein the screen is substantially transparent to visible light.

15. The video display system of claim 10 , wherein the screen is substantially transparent to infrared light.

16. The video display system of claim 10 , wherein the fluorescent dyes are configured to emit light having a predetermined wavelength in response to receiving light from the light source.

17. A vehicular video display system comprising:
a touch screen having first and second sides;
a plurality of pixels deposited on the first side, each formed of a plurality of fluorescent dyes and including an infrared sub-pixel,
a laser light source configured to project light onto the first side to illuminate at least a subset of the plurality of fluorescent dyes in a raster pattern to generate an image to be received by the touch screen; and
a camera configured to map any detected touches on the touch screen.

18. The video display system of claim 17 , wherein each pixel includes at least one of a red sub-pixel, a blue sub-pixel, and a green sub-pixel.

19. The video display system of claim 17 , wherein the screen is substantially transparent to visible light.

20. The video display system of claim 17 , The video display system of claim 1 , wherein the screen is substantially transparent to infrared light.
