Abstract
HUD（10）, including laser projector（11）, diffusion sheet（12）, Image compounding device（13）And anti-dazzling screen（14）.Laser projector sends image strip.Diffusion sheet has reflecting surface（121）To receive and diffusely reflect the image strip from laser projector.Image compounding device receives the image strip reflected from diffusion sheet, to form the virtual image（P1）, thereby user the virtual image and outdoor scene with virtual image the same side are seen by Image compounding device.Anti-dazzling screen includes fence structure, and wherein fence structure is arranged on the reflecting surface of diffusion sheet.
Description
Technical field
The invention relates to a kind of HUD, and in particular to a kind of reflective HUD.
Background technology
Existing HUD, such as U.S. Patent Bulletin US 7, the head-up-display system disclosed by 990,620 in the case of ambient light is stronger, can cause the contrast or brightness ratio of the virtual image produced by it to decline.
The content of the invention
The purpose of the present invention is proposing a kind of HUD, it is possible to decrease influence of the ambient light to the contrast of the virtual image produced by it.
To reach above-mentioned purpose, the present invention proposes a kind of HUD, and it includes laser projector, diffusion sheet, Image compounding device and anti-dazzling screen.Laser projector sends image strip.Diffusion sheet has reflecting surface to receive and diffusely reflect the image strip from laser projector.Image compounding device receives the image strip reflected from diffusion sheet, to form the virtual image, and thereby user sees the virtual image and outdoor scene with virtual image the same side by Image compounding device.Anti-dazzling screen includes fence structure, and wherein fence structure is arranged on the reflecting surface of diffusion sheet.
The HUD that the present invention is provided, in the case of ambient light is stronger, the virtual image produced by it still has preferable contrast.
For above and other objects, features and advantages of the invention can be become apparent, preferred embodiment cited below particularly, and coordinate accompanying drawing, describe in detail as follows.
Brief description of the drawings
Fig. 1 is the schematic diagram of the HUD according to one embodiment of the invention.
Fig. 2 is the schematic diagram of the HUD according to another embodiment of the present invention.
Fig. 3 is the schematic diagram of the anti-dazzling screen according to one embodiment of the invention.

Embodiment
Fig. 1 is the schematic diagram of the HUD according to one embodiment of the invention.Fig. 1 is refer to, HUD 10 includes laser projector 11, diffusion sheet 12, Image compounding device 13 and anti-dazzling screen 14.Laser projector 11 sends image strip.Diffusion sheet 12 has reflecting surface 121 to receive and diffusely reflect the image strip from laser projector 11.Image compounding device 13 receives the image strip reflected from diffusion sheet 12, to form virtual image P1, and thereby user sees virtual image P1 and outdoor scene with virtual image P1 the same sides by Image compounding device 13.Anti-dazzling screen 14 includes fence structure（Do not illustrated in figure）, wherein fence structure is arranged on the reflecting surface 121 of diffusion sheet 12, to stop that wide-angle ambient light is reflected into Image compounding device 13 by diffusion sheet 12, it is possible to decrease influence of the ambient light to the contrast of the virtual image.
In the present embodiment, diffusion sheet 12 can be white plastic sheet, and anti-dazzling screen 14 can be ultra tiny blinds fenestrated membrane（microlouver film）.In the present embodiment, HUD 10 can be used for vehicle with Projection Display running information image, and can be with integrated in one apparatus and located at in-car top.
Fig. 2 is the schematic diagram of the HUD according to another embodiment of the present invention.Fig. 2 is refer to, HUD 20 includes laser projector 21, diffusion sheet 22, Image compounding device 23 and anti-dazzling screen 24.Laser projector 21 sends image strip.Diffusion sheet 22 has reflecting surface 221 to receive and diffusely reflect the image strip from laser projector 21.Image compounding device 23 receives the image strip reflected from diffusion sheet 22, to form virtual image P2, and thereby user sees virtual image P2 and outdoor scene with virtual image P2 the same sides by Image compounding device 23.Anti-dazzling screen 24 includes fence structure（Do not illustrated in figure）, wherein fence structure is arranged on the reflecting surface 221 of diffusion sheet 22, to stop that wide-angle ambient light is reflected into Image compounding device 23 by diffusion sheet 22, it is possible to decrease influence of the ambient light to the contrast of the virtual image.
In the present embodiment, diffusion sheet 22 can be white plastic sheet, and anti-dazzling screen 24 can be ultra tiny blinds fenestrated membrane.In the present embodiment, HUD 20 can be used for vehicle with Projection Display running information image, and typically using discrete mode located at in-car, such as laser projector 21 can be located at roof, diffusion sheet 22 and anti-dazzling screen 24 can be located at instrument board upper stage, and Image compounding device 23 can be located at windshield.
Fig. 3 is the schematic diagram of the anti-dazzling screen according to one embodiment of the invention.Fig. 3 is refer to, anti-dazzling screen 34 includes light transmission piece 341 and lighttight fence structure 342.Fence structure 342 is arranged in light transmission piece 341.Light transmission piece 341 is arranged on the reflecting surface 321 of diffusion sheet 32.
Although the present invention is disclosed above with preferred embodiment; so it is not limited to the present invention, any those skilled in the art, without departing from the spirit and scope of the present invention; when can make a little change and retouching, therefore protection scope of the present invention is when by being defined that claims are defined.
