Abstract
Head -up display (10) are including laser projection ware (11), diffusion piece (12), image synthesizer (13) and anti -dazzling screen (14). The laser projection ware sends the image light beam. The diffusion piece has plane of reflection (121) in order to receive and to spread the image light beam that the ground return comes from the laser projection ware. The image light beam of self -diffusion piece reflection is received by the image synthesizer to form the virtual image (P1), the user sees the virtual image and the outdoor scene of the virtual image with one side through the image synthesizer by this. The anti -dazzling screen includes fence structure, and wherein fence structure sets up on the plane of reflection of diffusion piece.
Description
Technical field
This utility model 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, when ambient light is stronger, can cause the contrast of the virtual image produced by it or brightness ratio to decline.
Utility model content
The purpose of this utility model is proposing a kind of HUD, it is possible to decrease the ambient light impact on the contrast of the virtual image produced by it.
For reaching above-mentioned purpose, the utility model proposes a kind of HUD, it includes laser projector, diffusion sheet, Image compounding device and brake sack.Laser projector sends image strip.Diffusion sheet has reflecting surface to receive and to reflect the image strip from laser projector diffusely.Image compounding device receives the image strip from diffusion sheet reflection, and to form the virtual image, thereby user sees the virtual image and the outdoor scene with virtual image the same side by Image compounding device.Brake sack includes fence structure, and wherein fence structure is arranged on the reflecting surface of diffusion sheet.
The HUD that this utility model provides, when ambient light is stronger, the virtual image produced by it still has preferable contrast.
For the above and other objects, features and advantages of this utility model can be become apparent, preferred embodiment cited below particularly, and coordinate accompanying drawing, describe in detail as follows.

Detailed description of the invention
Fig. 1 is the schematic diagram of the HUD according to this utility model one embodiment.Refer to Fig. 1, HUD 10 includes laser projector 11, diffusion sheet 12, Image compounding device 13 and brake sack 14.Laser projector 11 sends image strip.Diffusion sheet 12 has reflecting surface 121 to receive and to reflect the image strip from laser projector 11 diffusely.Image compounding device 13 receives the image strip from diffusion sheet 12 reflection, and to form virtual image P1, thereby user sees virtual image P1 and the outdoor scene with virtual image P1 the same side by Image compounding device 13.Brake sack 14 includes fence structure (not illustrating in figure), and 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 the ambient light impact on the contrast of the virtual image.
In the present embodiment, diffusion sheet 12 can be white plastic sheet, and brake sack 14 can be ultra tiny BAIYE fenestrated membrane (microlouver film).In the present embodiment, HUD 10 may be used for vehicle with Projection Display running information image, and can integrated in one apparatus and be located at car inner top.
Fig. 2 is the schematic diagram of the HUD according to another embodiment of this utility model.Refer to Fig. 2, HUD 20 includes laser projector 21, diffusion sheet 22, Image compounding device 23 and brake sack 24.Laser projector 21 sends image strip.Diffusion sheet 22 has reflecting surface 221 to receive and to reflect the image strip from laser projector 21 diffusely.Image compounding device 23 receives the image strip from diffusion sheet 22 reflection, and to form virtual image P2, thereby user sees virtual image P2 and the outdoor scene with virtual image P2 the same side by Image compounding device 23.Brake sack 24 includes fence structure (not illustrating in figure), and 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 the ambient light impact on the contrast of the virtual image.
In the present embodiment, diffusion sheet 22 can be white plastic sheet, and brake sack 24 can be ultra tiny BAIYE fenestrated membrane.In the present embodiment, HUD 20 may be used for vehicle with Projection Display running information image, and typically uses discrete mode to be located in car, as laser projector 21 can be located at roof, diffusion sheet 22 and brake sack 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 brake sack according to this utility model one embodiment.Refer to Fig. 3, brake sack 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 this utility model is disclosed above with preferred embodiment; so it is not limited to this utility model; any those skilled in the art; without departing from spirit and scope of the present utility model; when making a little change and retouching, protection domain the most of the present utility model is when with being as the criterion that claims are defined.
