Description
Technical field:
This utility model, about PDLC field, is specifically related to transparent projection film and applies the projection screen of this transparent projection film.
Background technology:
The projection screen used in the market has glass curtain, moulds curtain, metal curtain etc. in vain.These screens have a common point to be exactly one side Projection Display, i.e. beholder can only can only to watch image in the side of screen, and the opposite side of screen cannot show any information.Along with the development of shadow casting technique, all kinds of Novel projection screens arise at the historic moment, and transparent projection screens development in recent years is very fast, and various product emerges in an endless stream.Along with the development of application end, the following application amount in places such as show window, showcase, billboard, household and office teaching will be greatly increased.
Transparent projection screens is to make spectators can see the scenery after screen across screen, can see again the Special Projection screen projecting image on screen clearly, have the miraculous effects every hovering thing magic imaging.Existing transparent projection screens technology is mainly line holographic projections film, this film imprints out microcosmic " hole, hole point point " with precision processing technology on plastic basis material, make the transmission on its surface of the incident projected light, reflect and scattering has individual reasonable layout, require that its transparency is good, then its imaging is the poorest, otherwise require that its imaging is good, then its transparency is naturally the poorest, for example incident projected light has the light transmission of 50%, scatter before then may having the light of 30%, the light back scattering of 20%, imaging effect is just being thrown the most similar with rear-projection.
Patent CN1350510 discloses and utilizes glass microsphere and containing the rear projection screen manufacture method of glass microsphere, and the refractive index of patent requirements glass microsphere is not more than 1.70, wherein defective in microsphere sum is less than 15%, and diameter is less than 150 microns；United States Patent (USP) 5,563,738 (Vance) point out to use the microsphere of high index, this patent to also indicate that, it is necessary to remove non-round, size is unaccommodated and the microsphere that fades, in order to obtain uniform outward appearance；Chinese patent CN203118395U discloses a kind of holographic projection advertisement window；Patent CN201359678 patent name high-definition projection screen discloses and the front lighting of PET film sheet is carved into microprism that several striped stride uprightly arrange to improve gain, contrast is improved again by all painting pressures Lycoperdon polymorphum Vitt crystallite extinction grating between the adjacent faceted pebble of microprism two-by-two, and improve, by arranging crystallite reflectance coating, the ability that environment resistant light disturbs, thus improve the quality of high-definition projection screen in all directions.Chinese patent CN202522840U discloses a kind of liquid crystal double-sided projection screen of smectic phase, can realize biplane projection function；Chinese patent CN203340200U discloses the method utilizing PDLC to prepare projection display equipment；Chinese patent CN104090463A discloses and is composited by scatter-type polaroid and reflective polaroid, and two kinds of polaroid light transmission shafts are parallel.Scatter-type polaroid is made up of stretching polyethylene alcohol film folder polymer dispersed liquid crystal layer, wherein the optical principle of strained polymer dispersed LCD scatter-type polaroid is, stretching liquid crystal droplet is elongated spheroid-like, in liquid crystal droplet, liquid crystal molecule is orientated approximately along draw direction, in stretched vertically direction, liquid crystal ordinary refraction index is close with refractive index polymer, light transmission.Along draw direction, liquid crystal very optical index is unequal with refractive index polymer and differs bigger, light scattering.The optical principle of multilayer film reflective polaroid is, different membrane materials stretching anisotropy are different, stretched vertically direction ordinary refraction index close to identical, light transmission.Bigger along draw direction very optical index difference, a large amount of transmission of neighboring layer interfaces light, trace reflects, but when the number of plies is a lot, reflection light takes care of the pence the most considerable.The existing multilayer film reflective polaroid hundreds of layer of the brightness enhancement film number of plies, is known as " multi-layer steamed bread " structure, and outward appearance is the brightest such as silver mirror.
