Description
Technical field
The utility model relates to rear-projection display system, especially relates to a kind of overlarge area without splicing optics rear projection hard screen.
Background technology
Rear-projection display system, with the powerful resistibility of its superior picture effect and surround lighting to external world, become the first-selection of indoor each large field display terminal, and the display technique of its core engineering projector is also tending towards perfect; But another vitals rear projection screen that rear-projection display system relies on but is not developed fully, so the powerful effect of engineering projector in brightness after the transmission of rear projection screen, contrast, color etc. is had a greatly reduced quality, its advantage cannot be given full play to.In addition, rear projection screen common is at present many is spliced into the larger rear projection screen of an area by junior unit, and its splicing seams often affects the viewing effect of picture.Have sub-fraction producer can produce the rear projection screen of nothing splicing, but it is lower to the transmission scattering power of light, composition is mixed and disorderly, simple structure, and cause final display frame solar effect serious, fuzzy pictures, color distortion, cannot show fine and smooth picture.
Summary of the invention
The purpose of this utility model is the problems referred to above existed for existing rear-projection display system, there is provided light processing power strong, the picture color demonstrated is undistorted, brightness and contrast decays minimum, ultimate attainment black expressive force is strong, curtain base good toughness, can customize size arbitrarily, and a kind of overlarge area of rollable transport is without splicing optics rear projection hard screen.
The utility model is provided with wavy optics diffuse reflector, dentation light refraction layer and 3 layers of screen base;
Described wavy optics diffuse reflector and dentation light refraction layer are located on the two sides of 3 layers of screen base respectively, wavy optics diffuse reflector is spectators face, dentation light refraction layer is rear-projection face, the surface spraying aterrimus photoreception granule of wavy optics diffuse reflector, the throw light directive dentation light refraction layer that engineering projector sends, the scattered beam directive spectators of wavy optics diffuse reflector.
Described 3 layers of screen base can adopt macromolecule complex photographic material to make.
Rear-projection face of the present utility model is face, dentation light refraction layer place, the incident ray that engineering projector sends is through the adjustment of dentation light refraction layer, light path is tending towards parallel, the ray density that each orientation projected and intensity basically identical, the picture brightness demonstrated, uniform in color, word edge impulse-free robustness.
Spectators face of the present utility model is face, wavy optics diffuse reflector place, and its special optical structure can carry out diffuse reflection to extraneous light such as light, eliminates the impact of extraneous light on spectators and rear-projection display system inside; Its surface spraying aterrimus photoreception granule, to strengthen the expressive force of rear-projection display system to ultimate attainment black.
Because 3 layers of screen base can adopt macromolecule complex photographic material to form, therefore its toughness is strong, shock-resistant and rollable transport; Because light transmission capacity in the photosensitive factor is strong, therefore the decay of its throw light to engineering projector is minimum, and color rendition degree is high; It adopts special producing technique compression molding, therefore size can customize arbitrarily.
The utility model efficiently solves the problems such as large-scale rear projection screen solar effect, brightness decay are large, color distortion, picture of its display has the features such as high-contrast, high definition, brightness uniformity, color be undistorted, size can be customized arbitrarily, toughness is high, omnidistance employing automatic producing technology, cost is low, is applicable to all kinds of rear-projection display system.
Accompanying drawing explanation
Fig. 1 is the structure composition schematic diagram of the utility model embodiment.
Fig. 2 is the operating diagram that the utility model embodiment eliminates extraneous light.
Embodiment
Embodiment will be described further the utility model by reference to the accompanying drawings below.
As illustrated in fig. 1 and 2, the utility model embodiment is provided with wavy optics diffuse reflector 1, dentation light refraction layer 2 and 3 layers of screen base 3.Described wavy optics diffuse reflector 1 and dentation light refraction layer 2 are located on the two sides of 3 layers of screen base 3 respectively, wavy optics diffuse reflector 1 is spectators face, dentation light refraction layer 2 is rear-projection face, the surface spraying aterrimus photoreception granule of wavy optics diffuse reflector 1, the throw light A directive dentation light refraction layer 2 that engineering projector 4 sends, the scattered beam B directive spectators of wavy optics diffuse reflector 1.
Described 3 layers of screen base can adopt macromolecule complex photographic material to make.
Its rear-projection face is face, dentation light refraction layer 2 place, the incident ray A that engineering projector 4 sends is through the adjustment of dentation light refraction layer 2, and light path is tending towards parallel, the ray density that each orientation projected and intensity basically identical, the picture brightness demonstrated, uniform in color, word edge impulse-free robustness.
Its spectators face is face, wavy optics diffuse reflector 1 place, and its special optical structure can carry out diffuse reflection to extraneous light C such as light, eliminates the impact of extraneous light on spectators and rear-projection display system inside; Its surface spraying aterrimus photoreception granule, to strengthen the expressive force of rear-projection display system to ultimate attainment black.
Screen base 3 is made up of macromolecule complex photographic material, therefore its toughness is strong, shock-resistant and rollable transport; Because light transmission capacity in the photosensitive factor is strong, therefore the decay of its throw light to engineering projector 4 is minimum, and color rendition degree is high; It adopts special producing technique compression molding, therefore size can customize arbitrarily.
