Description
Technical field
The utility model relates to forward projection's optical screen, particularly a kind of incident ray reflection configuration for forward projection's optical screen.
Background technology
In recent years, along with the raising of the luminosity of projector own, most of projection screens need to use in natural light or very bright environment.Due to the problem of know-why, with general glass bead screen, when moulding curtain, ash curtain etc. and carry out projected image in vain, black pattern on the stronger projected image of surround lighting is thereupon brighter, the contrast degradation of projected image, image color is thin out because of the surround lighting that superposeed, and causes color reducibility very undesirable.
Thereby use projection screen under bright light environments, and especially forward projection's screen, the true reappearance ability of the color rendition performance, particularly black pattern of solution projected image, seems particularly important.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, provides a kind of and have high-gain under bright light environments, and high-contrast also has the incident ray reflection configuration for forward projection's optical screen without surperficial dazzle and high color rendition degree simultaneously.
The purpose of this utility model is achieved through the following technical solutions: a kind of incident ray reflection configuration for forward projection's optical screen, it comprises basalis and microprism array structure, multiple microprism array structures are arranged on basalis evenly and at intervals, the xsect of described single microprism array structure is triangular structure, the incident ray that comes from projector is radiated on the side of microprism array structure, microprism array structure is also provided with metal medium minute surface reflective membrane near projector's one side, the outside of metal medium minute surface reflective membrane is also provided with light diffuse reflector.
Described metal medium minute surface reflective membrane starts from the top of microprism array structure, extend to bottom surface side along microprism array structure, and terminate in the incident ray intersection point place crossing with this microprism array structure, and incident ray just passes the microprism array structure top of adjacent and close projector one side.
The section of described light diffuse reflector is circular arc, ellipse or rectangle.
The utlity model has following advantage: under bright light environments, have high-gain, high-contrast also has without surperficial dazzle and high color rendition degree simultaneously.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
In figure: 1-basalis, 2-microprism array structure, 3-metal medium minute surface reflective membrane, 4-light diffuse reflector, 5-incident ray.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1, a kind of incident ray reflection configuration for forward projection's optical screen, it comprises basalis 1 and microprism array structure 2, multiple microprism array structures 2 are arranged on basalis 1 evenly and at intervals, the xsect of described single microprism array structure 2 is triangular structure, the incident ray 5 that comes from projector is radiated on the side of microprism array structure 2, microprism array structure 2 is also provided with metal medium minute surface reflective membrane 3 near projector's one side, and the outside of metal medium minute surface reflective membrane 3 is also provided with light diffuse reflector 4.
Described metal medium minute surface reflective membrane 3 starts from the top of microprism array structure 2, extend to bottom surface side along microprism array structure 2, and terminate in the incident ray 5 intersection point place crossing with this microprism array structure 2, and incident ray 5 just passes microprism array structure 2 tops of adjacent and close projector one side.
The section of described light diffuse reflector 4 is circular arc, ellipse or rectangle.
Basalis 1 can be hard macromolecular material (as PMMA, PC, PVC etc.), with 2 pressing of microprism array structure layer to form hard curtain, also can be soft material (as TPU, EVA, PET, silicon rubber etc.), push formation with microprism array structure layer 2 simultaneously, or pressing again after forming respectively, forms soft curtain.Microprism array structure layer 2 is made up of black material visible ray to high-absorbility, its cut-open view is jagged prism array, the adjacent crown distance of microprism array structure layer 2 is by the direction away from projector, can be to remain unchanged, also can be to reduce gradually, and this spacing is at least 1/2 of projected image pixel wide, or less, especially taking 1/10 as best.
Metal medium minute surface reflective membrane 3 can be made up of argent, aluminium, copper, gold etc., thickness can be 0.05 μ m between 1 μ m, taking 0.3 μ m as best, metal medium minute surface reflective membrane 3 has high specular reflectance to visible ray, light diffuse reflector 4 is by BaSO
4or TiO
2form Deng light diffusion material, be arranged at metal medium minute surface reflective membrane 3 outsides on projector's incident ray shadow surface 7, its width equals the width of metal medium minute surface reflective membrane 3, the thickness 1 μ m～50 μ m of light diffuse reflector 4, taking 25 μ m as best, light diffuse reflector 4 has diffusivity to projector's incident ray, change the original direction of propagation of incident ray, incident ray energy is redistributed in space, and can adjust accordingly according to different demands, projector's incident ray via this light diffuse reflector 4 after, it can be Lambertian reflection light distribution, also can be to distribute by the diffuse reflection light intensity of certain chief ray direction.
