Abstract

A display arrangement for displaying information perspectively or three-dimensionally has a first and second display devices. The first display device is positioned behind a semitransparent mirror and displays a first information which is directly viewed through the semitransparent mirror. The second display device is positioned to intersect the first display device at an acute angle and displays a second information downwardly. The second information from the second display device is reflected by the semitransparent mirror to be viewed indirectly. Since the virtual image of the second information is formed on a plane which is symmetric to the second display device with respect to the semitransparent mirror, it is viewed as displayed perspectively or three-dimensionally.

Claims

1. A display arrangement for a vehicle having a windshield glass, an instrument panel provided below said windshield glass and in front of a driver'"'"'s seat, and a hood for said instrument panel extending between said windshield glass and said instrument panel toward said driver'"'"'s seat, said display arrangement comprising:

a display device provided in said hood for displaying in a substantially downward direction information arranged in a first pattern indicative of a first condition of said vehicle, said first pattern extending in substantially the same direction as said display device extends from said instrument panel, said display device including means for providing substantially downward directed light in said first pattern; and

a mirror panel provided in said instrument panel at an acute angle relative to said display device, said mirror panel reflecting light from said display device toward said driver'"'"'s seat, in such a manner that a virtual image of said first pattern is formed in perspective behind said mirror panel.

2. A display device according to claim 1, wherein said mirror panel is a semi-transparent panel for transmission and reflection of light.

3. A display device according to claim 2, further comprising another display device provided in said instrument panel for displaying toward said driver'"'"'s seat a second information arranged in a second pattern indicative of a second condition of said vehicle.

4. A display device according to claim 3, wherein said another display device is positioned behind said semi-transparent panel.

5. A display device according to claim 4, wherein said another display device is positioned in front of a plane where said virtual image is formed.

6. A display arrangement according to claim 1, wherein said second pattern is shaped in a bar graph extending diagonally.

7. A display arrangement according to claim 1, wherein said display device further includes:

means for providing a colored light; and

means for transmitting said colored light to said mirror panel in said second pattern.

8. A display arrangement according to claim 7, wherein said colored light providing means includes:

a light source; and

a colored filter for coloring light from said light source.

9. A display arrangement according to claim 8, wherein said hood has an opening through which sunlight incident through said windshield glass passes in a substantially downward direction, and wherein said colored filter is provided in said hood opening for coloring said sunlight incident thereto.

10. A display arrangement according to claim 9, further comprising a light conductive plate for transmitting light from said light source therethrough to said colored filter.

11. A display arrangement according to claim 10, wherein said transmitting means comprises a liquid crystal panel having electrodes shaped in said first pattern.

12. A display arrangement according to claim 3 wherein said another display device has a display surface that is parallel to said mirror panel.

13. A display arrangement for a vehicle having a windshield glass, an instrument panel provided below said windshield glass and in front of a driver'"'"'s seat, and a hood for said instrument panel extending between said windshield glass and said instrument panel toward said driver'"'"'s seat, said display arrangement comprising:

a first display device provided in said instrument panel for displaying toward said driver'"'"'s seat information arranged in a first pattern indicative of a first condition of said vehicle;

a second display device provided in said hood for displaying in a substantially downward direction information arranged in a second pattern indicative of a second condition of said vehicle, said second display device including means for providing in a substantially downward direction light in said second pattern; and

a mirror panel provided in said instrument panel at an acute angle relative to said second display device, said mirror panel reflecting light from said second display device toward said driver'"'"'s seat in such a manner that a virtual image of said second pattern is formed in perspective behind said first display device so that said first pattern and said virtual image of said second pattern are displayed three-dimensionally in said instrument panel.

14. A display arrangement according to claim 13, wherein said hood has an opening through which sunlight incident through said windshield glass passes substantially in a downward direction, and wherein said light providing means of said second display device has a colored filter provided in said hood opening for coloring said sun light incident thereto and means for shaping said sun light from said colored filter into said second pattern.

15. A display arrangement according to claim 14, wherein said second display device includes a light source provided adjacent to said hood opening for emitting light toward said colored filter when activated, and wherein said shaping means comprises a liquid crystal panel having electrodes shaped in said second pattern.

16. A display arrangement according to claim 13, wherein said mirror panel is semitransparent, and wherein said first display device is positioned behind said mirror panel but in front of a plane where the virtual image of said second pattern is formed.

17. A display arrangement according to claim 16, wherein said second display device includes a light source provided in said hood for emitting light, and wherein said light providing means includes first means for coloring the light from said light source and second means for shaping the colored light from said first means into said second pattern

18. A display arrangement according to claim 16, wherein said second display device includes light source provided in said hood for emitting light, a light conductive plate for transmitting light from said light source therethrough, a liquid crystal panel having an electrode shaped in said second pattern, and a colored filter sandwiched between said light conductive plate and said liquid crystal panel for providing said liquid crystal panel with a colored light.

19. A display arrangement according to claim 13, wherein said second condition of said vehicle is a rotational speed of an engine in said vehicle.

20. A display arrangement according to claim 13 wherein said first display device has a display surface that is parallel to said mirror panel.
