Abstract
The utility model relates to an optical double view-field three-dimensional helmet display device, comprising a helmet housing, a display device, a data interface and an earphone. The display device is fixed on the front end of the helmet housing. The earphone is fixed on both sides of the helmet housing. The data interface is connected with a video frequency trigger by a data wire. The display device is composed of the video frequency trigger, a liquid crystal display, a diffusion plate, an LEEP optic block, a Fresnel prism and a signal winding displacement. The video frequency trigger is connected with the liquid crystal display by the signal winding displacement. The optic block is arranged between the Fresnel prism and the diffusion plate. The diffusion plate is arranged on one side of the liquid crystal display. The utility model has the advantages of simple structure, small volume, light weight, low cost and broad visual field. The optical double view-field three-dimensional helmet display device is suitable for browsing virtual scenes of a virtual reality system.
Description
Technical field
The utility model relates to a kind of Helmet Mounted Display, the three-dimensional helmet mounted display device of particularly a kind of optics double-view field.
Background technology
Helmet Mounted Display is one of important external equipment of virtual reality system.At present, the Helmet Mounted Display of domestic employing is less, mainly be to buy external Helmet Mounted Display to carry out virtual reality, existing monocular helmet mounted display device can only show two dimensional image, and the liquid crystal helmet mounted display device visual field with binocular demonstration is narrower, and the 3-D view third dimension of demonstration is not strong, and involves great expense, complex structure can not satisfy the needs of virtual reality technology research effectively.
The utility model content
The purpose of this utility model is in order to overcome the shortcoming that existing optics helmet mounted display device exists, provide a kind of simple in structure, volume is little, cost is low, the visual field is wide, can show the three-dimensional helmet mounted display device of optics double-view field of three-dimensional image, be applicable to that the virtual scene of virtual reality system is browsed.
The utility model comprises helmet shell, display unit, data-interface and earphone, display unit is fixed on the front end of helmet shell, earphone is fixed on the both sides of helmet shell, data-interface links to each other with the video trigger by data wire, described display unit is by the video trigger, LCD, diffusion sheet, the LEEP optical system, Fresnel prism and signal line are formed, the video trigger links to each other with LCD by signal line, optical system is arranged between Fresnel prism and the diffusion sheet, diffusion sheet is arranged on a side of LCD, the operation principle of this device is: the video data signal that data-interface transmits is presented on the LCD, amplify through optical system, obtain the picture of similar giant-screen.
The utlity model has simple in structure, volume is little, in light weight, advantage such as cost is low, the visual field is wide, is applicable to that the virtual scene of virtual reality system is browsed.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the cutaway view of Figure 1A-A;
Among the figure: 1 helmet shell, 2 display unit, 3 data-interfaces, 4 earphones, 5 left video triggers, 6 right video triggers, 7 left LCDs, 8 right LCDs, 9 left signal winding displacements, 10 right signal winding displacements, 11 left diffusion sheets, 12 right diffusion sheets, 13 left LEEP optical systems, 14 right LEEP optical systems, 15 left Fresnel prisms, 16 right Fresnel prisms.
The specific embodiment
As shown in the figure, further specify the technical solution of the utility model and the course of work in conjunction with example.
The three-dimensional helmet mounted display device of a kind of optics double-view field, this device comprises helmet shell 1, display unit 2, data-interface 3, earphone 4 is formed, display unit 2 is fixed on the front end of helmet shell 1, earphone 4 is fixed on the both sides of helmet shell 1, data-interface 3 links to each other with 6 with left and right sides video trigger 5 respectively by data wire, display unit 2 is by left and right sides video trigger 5 and 6, left and right sides LCD 7 and 8, left and right sides diffusion sheet 11 and 12, left and right sides LEEP optical system 13 and 14, left and right sides Fresnel prism 15 and 16, left and right sides signal line 9 and 10 is formed, left and right sides video trigger 5 links to each other with 8 with left and right sides LCD 7 with 10 by left and right sides signal line 9 respectively with 6, left and right sides LEEP optical system be separately positioned on left and right sides Fresnel prism 15 and 16 and left and right sides diffusion sheet 11 and 12 between, left and right sides diffusion sheet 11 and 12 is separately positioned on a side of left and right sides LCD 7 and 8, and left and right sides LCD 7 and 8 adopts 2.4 inches respectively, resolution ratio is the liquid crystal micro display of 640 (H) * 320 (V).Its course of work is: data-interface 3 receives virtual scene image and the acoustic information that computer transmits, acoustic information is transported to the earphone 4 of helmet shell 1 by tone frequency channel wire, two width of cloth that Same Scene is drawn out are respectively passed to the left video trigger 5 and the right video trigger 6 of display unit 2 respectively by video line corresponding to the different images of left and right sides eyes, left and right sides video trigger 5 and 6 is passed to left and right sides LCD 7 and 8 to two width of cloth images of left and right sides viewpoint respectively, left and right sides LCD 7 and 8 light see through left and right sides diffusion sheet 11 and 12 and are diffuse reflection output, be input to the amplification of carrying out image in left and right sides LEEP optical system 13 and 14, provide the wide as far as possible visual field to eyes, the left and right sides Fresnel prism 15 and 16 that plastics are made makes the binocular image further draw close mutually and converge, because left and right sides LCD 7 almost becomes an angle of 90 degrees vertical with 8 with the sight line of eyes, thereby the visual field that forms is wideer, the three-dimension space image that third dimension is stronger.
