Abstract
The utility model discloses an optical projection curtain of anti environment light, including the curtain body, the curtain body includes PET stratum basale, imaging layer and transmission layer, and the upper surface of PET stratum basale is equipped with and is the microlens array structure that the concave lenticule constitutes by a set of, the internal surface of every lenticule has plated the aluminium rete, the imaging layer is covered in the upper surface of PET stratum basale, and the transmission layer is located on the imaging layer. The utility model discloses an optical projection curtain uses the lens optical property to increase the screen gain, under bright environment greatly increased the colorful degree and the contrast of projection picture, this projection curtain material is good, and friendly to environment is pollution -free, easily installs and use, and the projector is just being thrown to the disposable type that is applicable to on the market.
Description
Technical field
The utility model belongs to image projecting playback equipment, relates to the environment resistant light optical projection curtain of a kind of high-gain, high-contrast.
Background technology
Environment resistant light curtain sold on the market is also the mode using Typical spray front surface coating now, use silver color high-gain coating, higher gain can be presented, because silver coating is also by diffuse reflectance reflected image, surround lighting and projected light all can reflex to spectators and watch a little, and the raising of gain can't the interference of filter out context light.Projection screen contrast is because using silver coating when there being surround lighting, and curtain face contrast room for promotion is limited, and contrast has good performance compared to white curtain.
But existing environment resistant light high-gain curtain has higher gain relative to Bai Muyin, and when practical application, surround lighting is not fairly obvious, but is slightly better than white curtain.High-gain coating drops into the while that light carrying out diffuse reflection projector has also carried out diffuse reflection by the ambient light be incident upon in coating, when environmental light brightness rate has lifting, the brightness and contrast of imaging decreases, make projects images color dim, brightness of image reduces, until cannot see image on projection screen.So exist in existing environment resistant light curtain go to the bottom that brightness projection machine picture brightness is low, picture color is dim in the situation that surround lighting is bright, common white curtain and the performance of silver color curtain black field poor, the problem that contrast is low.
Utility model content
the technical matters solved:the utility model provides a kind of optical projection curtain of environment resistant light with high-gain, high-contrast.
technical scheme:a kind of optical projection curtain of environment resistant light, comprise curtain body, curtain body comprises PET base layer, imaging layer and transmission layer, the upper surface of PET base layer is provided with the microlens array structure be made up of one group of lenticule in spill, described each lenticular inside surface is coated with aluminum membranous layer, described imaging layer is overlying on the upper surface of PET base layer, and transmission layer is located on imaging layer.
Described lenticule is hemispherical dome structure, semiellipse spherical structure or parabolic surface structure.
The arrangement mode of described microlens array structure is one of rounded projections arranged, regular hexagon arrangement, rectangular arranged, radial arrangement, circular arrangement mode or is combined by wherein at least two kinds of arrangement modes.
Described imaging layer is grey black or light/dark balance imaging layer.
The material of described transmission layer is glass microballoon.
beneficial effect:optical projection curtain of the present utility model uses lenticular optical property to add screen gain, considerably increases colour vividness and the contrast of projected picture under bright light environments; This projection screen material is good, environmentally friendly, pollution-free, is easy to install and use, and is applicable to disposable type Zheng Tou projector on the market.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1 be PET base layer, 2 be microlens array structure in figure, 3 be aluminum membranous layer, 4 be imaging layer, 5 for transmission layer.
Embodiment
embodiment 1
A kind of optical projection curtain of environment resistant light, comprise curtain body, curtain body comprises PET base layer, imaging layer and transmission layer, the upper surface of PET base layer is provided with the microlens array structure be made up of one group of lenticule in spill, described each lenticular inside surface is coated with aluminum membranous layer, described imaging layer is overlying on the upper surface of PET base layer, and transmission layer is located on imaging layer.Lenticule is hemispherical dome structure, semiellipse spherical structure or parabolic surface structure.The arrangement mode of microlens array structure is one of rounded projections arranged, regular hexagon arrangement, rectangular arranged, radial arrangement, circular arrangement mode or is combined by wherein at least two kinds of arrangement modes.Imaging layer is grey black or light/dark balance imaging layer.The material of transmission layer is glass microballoon.
embodiment 2
PET base layer uses precision machined microlens array mould running roller, heating running roller to 250 degree Celsius, accurate control running roller contacts the Distance geometry roll-in time with PET, make it to impress out microlens array (simple lens specification is 15 μm * 15 μm), form the microlens array structure of a group, lenticule is hemispherical dome structure, and arrangement mode is rectangular arranged, the lenticular inside surface shaping to hot padding does vacuum coating process, plated aluminum rete.Then apply one deck imaging layer by coating process in the upper surface of PET base layer, this imaging layer adds color by PVC and reconciles into uniform grey black; Then glass microballoon is fixed on imaging layer surface by light-sensitive emulsion UV curing mode or alternate manner and forms transmission layer.
Light enters microlens array structure by imaging layer, and lens are focusing on light and on imaging layer, presenting image after reflecting, and image reflects light through transmission layer and arrives viewing point.Optical projection curtain, by specific microlens array reflection special angle light, is crossed all the other light beyond filtering projector light line, is improved projection screen gain.Curtain base material is tinted grey black background color, increases curtain contrast, compares white curtain contrast and improve more than 5 times.Projection screen curtain face adopts microstructure coating technique, makes while gain gets a promotion, and half gain visual angle increases.
Claims (5)
