Have the effect of being imaged every hovering object, main application fields include Window Display, interaction display, multimedia image displaying etc..
Polymer dispersed liquid crystals, also known as PDLC (polymer dispersed liquid crystal) are to utilize phase
Liquid crystal is evenly dispersed in the small droplet of micron dimension in organic solid-state polymer matrix body by isolation technics, due to by liquid crystal point
The optical axis for the small droplet that son is constituted is in and is freely orientated, and the refractive index of refractive index and matrix mismatches, when light passes through matrix
It is scattered strongly by droplet and is in opaque milky white state or translucent.The optical axis for applying electric field-tunable section liquid crystal droplet takes
To, when the two refractive index matches, presentation transparent state.Electric field is removed, liquid crystal droplet has the light-scattering state for restoring initial, from
And it is shown.Milky is presented under obstructed electricity condition in polymer dispersed liquid crystal film, and it is first-class to be pasted onto window-glass, can use
Make rear projection type projecting apparatus screen, display effect is clear, and visual angle is wide in range.But after being powered, film is changing to pellucidity, can penetrate
Glass sees interior, under pellucidity, no Projection Display effect.Thus, polymer dispersed liquid crystal film is in terms of shadow casting technique
Using being extremely limited.
In view of this, special propose the present invention.
Invention content
The first object of the present invention is to provide a kind of line holographic projections film, is being powered with solving pdlc film in the prior art
Under state can not Projection Display effect the problem of.
The second object of the present invention is to provide a kind of preparation method of line holographic projections film, the preparation method operation letter
Single, reproducible, the stability for the line holographic projections film being prepared is good, can not only carry out back projection, but also can carry out orthographic projection.
The third object of the present invention is to provide a kind of application in projection screen of the line holographic projections film, by the throwing
Shadow film is set in glass surface or interlayer, and the mist degree and/or transparency of transparent projection film are controlled by external power supply.
In order to realize that the above-mentioned purpose of the present invention, spy use following technical scheme：
