Background technology

With the gradual quickening of city process, the quantity of building increases severely year by year.At the same time, the number of plies of building is also more next More, some megaplex building have become the landmark building in city（City terrestrial reference）.Along with the hair of city process Exhibition, sponsored media is also increasingly prevailing, is projected out updated look product using huge LED screen or LCD screen or enterprise marks Will has become a kind of popular prevailing custom.

In order to improve projection quality, people have produced reflective membrane（Such as aluminium foil reflective sheeting）, the surface of reflective membrane can be with Diffusing reflection is formed, by the way that reflective membrane is adhered on the windowpane of building, the reflecting rate of building can be increased substantially, therefore The requirement for projecting acc power is then greatly lowered.

However, above-mentioned under the influence of high-rise building and sponsored media, people are by shadow casting technique（Such as 3D projections）Using In building, be projected out miscellaneous design, to form bright and colourful media advertisement or light show, and then publicize and Live beautifying city.In view of the height of city building is general all at tens meters to hundreds of meters, therefore suspension LED screen can cause The huge load-bearing of windowpane, suspension projection screen can wave with the wind again.

In existing projection process, multiple high power projectors directly focus to the light beam of high lumen on building, Design or image are formed on the wall and windowpane of building.In projection, the building of gravel wall exist reflecting rate compared with The problem of low and image quality is poor；There is specular reflectivity in the building of glass curtain wall and transmissivity is high（Light is refracted to day It is empty and be transmitted through inside building）The problem of, when serious, the building of gravel wall and the building image quality of glass wall are very poor, It can not even be imaged at all.

Throw reflective membrane in order to reduce cost and lifting and the problem of light transmittance difference again be present, when handling official business daytime, due to light Reflective membrane can not be passed through to enter inside building, therefore the illuminance inside building is relatively low, have impact on normal office work and people couple The primary demand of sunlight.

Existing Patent No.:CN203520005U discloses a kind of building glass curtain wall projection imaging film, the projection imaging Film includes a base membrane layer, and the base membrane layer, which is gone into battle, shows multiple printing opacity primitives, and array is gone back on the base membrane layer multiple reflective primitives, Those printing opacity primitives and those reflective spaced settings of primitive, those printing opacity primitives are transmissive to light, keep inside building Normal intensity of illumination, it ensure that the demand of normal office work and people to sunlight.
