Abstract

An instrument panel including at least one instrument indicator positioned in the panel. At least one active display is positioned in the panel and is capable of displaying images from data provided to the display.

Claims

1. A display system comprising:

a display device for providing images;

a first light source for emitting light; and

a first light collection lens system comprising a hyperspheroid hollow lens having an optical axis, the hollow lens for collecting the light emitted from the first light source and directing the light in a first beam of light to the display device for illuminating the images on the display device for viewing, the hollow lens having a substantially spherical interior portion and an outer surface bulging forward along the optical axis relative to the substantially spherical interior portion, the first light source extending within the substantially spherical interior portion.

2. The display system of claim 1 in which the display device is an active liquid crystal display.

3. The display system of claim 2 in which the first light source is an LED.

4. The display system of claim 3 in which the hollow lens is substantially spherical with an opening on one side.

5. The display system of claim 4 in which the hollow lens has spherically shaped inner and outer surfaces with centers offset from each other.

6. The display system of claim 5 further comprising a projection lens for projecting images from the liquid crystal display.

7. The display system of claim 6 further comprising a screen for displaying the images projected by the projection lens.

8. The display system of claim 7 in which the first light collection lens system further comprises a condenser lens positioned adjacent to the hollow lens for further condensing the first beam of light.

9. The display system of claim 8 further comprising a dispersion lens positioned adjacent to the liquid crystal display for dispersing the first beam of light on the liquid crystal display.

10. The display system of claim 9 further comprising:

a second light source comprising an LED for emitting light, the light from the first and second light sources being different colors;

a second light collection lens system comprising a hollow lens for collecting the light emitted from the second light source and directing the light in a second beam of light, and a condenser lens positioned adjacent to the hollow lens for further condensing the second beam of light; and

a beam splitter for directing the second beam of light through the dispersion lens to the liquid crystal display.

11. The display system of claim 10 further comprising a mirror for directing images projected by the projection lens onto the screen.

12. The display system of claim 10 in which one of the first and second light sources emits green light at about 530 nm and the other emits red light at about 645 nm.

13. The display system of claim 10 in which the display system is contained within a housing, the housing being about 3.5 inches long, 1.5 inches high and 1 inch wide.

14. The display system of claim 13 in which the screen is about 1×

1.3 inches and the displayed images have a dimension of at least 3×

4 inches.

15. The display system of claim 10 further comprising:

a third light source comprising an LED for emitting light, the light from the first, second and third light sources being different colors;

a third light collection lens system comprising a hollow lens for collecting the light emitted from the third light source and directing the light in a third beam of light, and a condenser lens positioned adjacent to the hollow lens for further condensing the third beam of light; and

wherein the beam splitter also directs the third beam of light through the dispersion lens to the liquid crystal display.

16. The display system of claim 15 in which the different colors are green, red and blue.

17. A method of displaying images with a display system comprising:

providing the images with a display device;

emitting light with a first light source; and

collecting the light emitted from the first light source and directing the light in a first beam of light to the display device with a first light collection lens system comprising a hyperspheroid hollow lens having an optical axis, the hollow lens for illuminating the images on the display device for viewing, the hollow lens having a substantially spherical interior portion and an outer surface bulging forward along the optical axis relative to the substantially spherical interior portion, the first light source extending within the substantially spherical interior portion.

18. The method of claim 17 further comprising providing the display device with an active liquid crystal display.

19. The method of claim 18 further comprising forming the first light source from an LED.

20. The method of claim 19 further comprising forming the hollow lens to be substantially spherical with an opening on one side.

21. The method of claim 20 further comprising providing the hollow lens with spherically shaped inner and outer surfaces having centers offset from each other.

22. The method of claim 21 further comprising projecting images from the liquid crystal display with a projection lens.

23. The method of claim 22 further comprising displaying the images projected by the projection lens on a screen.

24. The method of claim 23 further comprising providing the first light collection lens system with a condenser lens positioned adjacent to the hollow lens for further condensing the first beam of light.

25. The method of claim 24 further comprising positioning a dispersion lens adjacent to the liquid crystal display for dispersing the first beam of light on the liquid crystal display.

26. The method of claim 25 further comprising:

emitting light with a second light source comprising an LED, the light from the first and second light sources being different colors;

collecting the light emitted from the second light source and directing the light in a second beam of light with a second light collection lens system comprising a hollow lens and a condenser lens positioned adjacent to the hollow lens for further condensing the second beam of light; and

directing the second beam of light through the dispersion lens to the liquid crystal display with a beam splitter.

27. The method of claim 26 further comprising directing images projected by the projection lens onto the screen with a mirror.

28. The method of claim 26 further comprising emitting green light at about 530 nm with one of the first and second light sources and emitting red light at about 645 nm with the other light source.

29. The method of claim 26 further comprising containing the display system within a housing, the housing being about 3.5 inches long, 1.5 inches high and 1 inch wide.

30. The method of claim 29 further comprising forming the screen to be about 1×

1.3 inches and the displayed images having a dimension of at least 3×

4 inches.

31. The method of claim 26 further comprising:

emitting light with a third light source comprising an LED, the light from the first, second and third light sources being different colors;

collecting the light emitted from the third light source and directing the light in a third beam of light with a third light collection lens system comprising a hollow lens and a condenser lens positioned adjacent to the hollow lens for further condensing the third beam of light; and

directing the third beam of light through the dispersion lens to the liquid crystal display with the beam splitter.

32. The method of claim 31 further comprising providing green, red and blue as the different colors.
