Abstract

In a high visibility head-up display system where display light outputted from a display part 12 is reflected near a position of a front window shield 7, a portion of a masking portion 2a that covers a circumferential portion of the front window shield 7 is enlarged to form an area-enlarged masking portion 2. The display light is outputted from the display part 12 in a portion of the front window shield 7 corresponding to the area-enlarged masking portion 2, and the display light is reflected on the area-enlarged masking portion 2. The area-enlarged masking portion 2 functions as a background part of a display.

Claims

1. A high visibility head-up display system where display light outputted from a display part of a head-up display unit is reflected near a position of a front window shield to provide a driver with a display produced by a virtual image due to the reflected light, the head-up display system characterized in that

an area-enlarged and colored portion is provided by a portion of a colored portion, which covers a circumferential portion of the front window shield, being enlarged, wherein

the display light outputting from the display unit is reflected on a portion of the front window shield corresponding to the area-enlarged and colored portion to provide the display due to the virtual image, and wherein

the area-enlarged and colored portion provides a background part of the display.

2. The high visibility head-up display system according to claim 1, wherein

an upper surface of an installment panel is dented downward at a position corresponding to the area-enlarged and colored portion to further enlarge the area-enlarged and colored portion.

3. The high visibility head-up display system according to claim 1, wherein

the area-enlarged and colored portion is coated in dark color.

4. The high visibility head-up display system according to claim 1, wherein

the area-enlarged and colored portion is arranged between a vehicle interior central portion in a lateral direction of a motor vehicle and a steering wheel.

5. The high visibility head-up display system according to claim 1, wherein

a graduation portion is provided at a boundary between the colored portion covering the circumferential portion of the front window shield at left and right sides of the area-enlarged and colored portion and a transparent portion of the front window shield, so as to make the boundary graded.

6. The high visibility head-up display system according to claim 5, wherein

the graduation portion is modestly and the area-enlarged and colored portion are formed to be moderately connected with each other so that a boundary portion between the graduation portion and the area-enlarged portion is made indistinct.

7. The high visibility head-up display system according to claim 1, wherein

the front window shield has a construction where two transparent plates are attached with each other by an adhesive layer, wherein

the area-enlarged and colored portion is arranged between the transparent plates at a vehicle front exterior side and the adhesive layer, and wherein

a vehicle interior side surface of the area-enlarged and colored portion has a rough surface.

8. The high visibility head-up display system according to claim 1, wherein

the area-enlarged and colored portion is formed by one of a printing, a coating and a film.

9. The high visibility head-up display system according to claim 2, wherein

the area-enlarged and colored portion is coated in dark color.

10. The high visibility head-up display system according to claim 2, wherein

the area-enlarged and colored portion is arranged between a vehicle interior central portion in a lateral direction of a motor vehicle and a steering wheel.

11. The high visibility head-up display system according to claim 3, wherein

the area-enlarged and colored portion is arranged between a vehicle interior central portion in a lateral direction of a motor vehicle and a steering wheel.

12. The high visibility head-up display system according to claim 2, wherein

a graduation portion is provided at a boundary between the colored portion covering the circumferential portion of the front window shield at left and right sides of the area-enlarged and colored portion and a transparent portion of the front window shield, so as to make the boundary graded.

13. The high visibility head-up display system according to claim 3, wherein

a graduation portion is provided at a boundary between the colored portion covering the circumferential portion of the front window shield at left and right sides of the area-enlarged and colored portion and a transparent portion of the front window shield, so as to make the boundary graded.

14. The high visibility head-up display system according to claim 4, wherein

a graduation portion is provided at a boundary between the colored portion covering the circumferential portion of the front window shield at left and right sides of the area-enlarged and colored portion and a transparent portion of the front window shield, so as to make the boundary graded.

15. The high visibility head-up display system according to claim 2, wherein

the front window shield has a construction where two transparent plates are attached with each other by an adhesive layer, wherein

the area-enlarged and colored portion is arranged between the transparent plates at a vehicle front exterior side and the adhesive layer, and wherein

a vehicle interior side surface of the area-enlarged and colored portion has a rough surface.

16. The high visibility head-up display system according to claim 3, wherein

the front window shield has a construction where two transparent plates are attached with each other by an adhesive layer, wherein

the area-enlarged and colored portion is arranged between the transparent plates at a vehicle front exterior side and the adhesive layer, and wherein
