Description
Technical field
This utility model relates to a kind of light modulation film, is specifically related to a kind of novel big visual angle electrically-controlled liquid crystal colour light modulation film.
Background technology
Eighties of last century late nineteen eighties, U.S. Polytronix, commercialization volume production liquid crystal film product are invented and authorized to PDLC technology by Texas, USA University of Kent.The earliest liquid crystal film product be mainly used in interlayer produce liquid crystal light modulation glass, and in the beginning of the nineties first Application in the project of U.S. NASA, this is known PDLC liquid crystal light modulation glass application case the earliest.As whole world PDLC liquid crystal light modulation film and the production pioneer of liquid crystal light modulation glass, Polytronix, Inc. the synonym of liquid crystal light modulation glass time the brand Polyvision Privacy Glass under is also taken as, America and Europe's the most therefore dimming glass is called Polyvision glass or secret glass (literal translation of Privacy Glass).The manufacturer such as Korea S, Japan started to get involved this field in middle nineteen nineties in last century later, and domestic manufacturer of China also puts into this production field after PDLC liquid crystal film comes out more than 10 years.
Without applied voltage when, intermembranous can not form regular electric field, the direction of optic axis of liquid crystal particle is random, presents disordered state, and its effective refractive index n0 does not mates with refractive index np of polymer.Incident ray is scattered strongly, and thin film is opaque or translucent.
Being applied with external voltage, the optical axis of liquid crystal particle is perpendicular to film surface arrangement, i.e. consistent with direction of an electric field.The ordinary refraction index of microgranule mates substantially with the refractive index of polymer, without obvious interface, constitutes a substantially homogeneous medium, so incident illumination will not scatter, and the transparent shape of thin film.Therefore, under the driving of extra electric field, PDLC possesses switch feature.
The factor of the electrooptic effect affecting PDLC photoswitch is many, such as the frequency etc. of thin and thick, liquid crystal and the mixing ratio of polymer of film, separated time, temperature and driving voltage.

Detailed description of the invention
See Fig. 1, be the one that the utility model proposes novel big visual angle electrically-controlled liquid crystal colour light modulation film structure chart.
As shown in Figure 1, a kind of novel big visual angle electrically-controlled liquid crystal colour light modulation film, including: transparent color substrate layer 1, first transparent substrate layer 3, first conductive layer 4, liquid crystalline polymer layer 5, second conductive layer 6, second transparent substrate layer 7, transparent color substrate layer 1 is bondd with the first transparent substrate layer 3 by transparent bonding layer 2, liquid crystalline polymer layer 5 is arranged between the first conductive layer 4 and the second conductive layer 6, first conductive layer 4 and the second conductive layer 6 are connected with the first transparent substrate layer 3 and the second transparent substrate layer 7 respectively, wherein liquid crystalline polymer layer 5 is different from the color of described transparent color substrate layer 1.
In this utility model embodiment, present during energising be liquid crystal polymer carry out with the color of colourful transparent base material overlapping after the third color.Present when disconnecting electricity is the color of liquid crystal in light modulation film.Wherein the capacitive load power consumption of the first conductive layer and the second conductive layer is little, power and energy saving, and the stable performance life-span is long.Can use as rear projection screen, meet office, home intelligent entertainment requirements.Light modulation film can shield infrared ray and the ultraviolet of more than 90%, and shielding infrared ray reduces heat radiation and transmission.And shield ultraviolet, can protect the furnishings of indoor that situations such as fading, aging, the disease that protection personnel are not caused by ultraviolet direct projection do not occur because of ultraviolet irradiation.
In this utility model embodiment, liquid crystalline polymer layer 5 includes polymer liquid crystal and the liquid crystal droplet being dispersed therein.PDLC (PDLC) be again liquid crystal light modulation film, it is by low molecular weight liquid crystal (1iquid crystal, it is abbreviated as LC) mix mutually with prepolymer Kuer UV65 glue, the most aggregated reaction, form micron-sized liquid crystal droplet to be evenly dispersed in macromolecule network, the dielectric anisotropy of recycling liquid crystal molecule obtains the material with electro-optic response characteristic, and it operates mainly between scattering states and clear state and has certain gray scale.Polymer dispersed liquid crystal film is the membrane material that liquid crystal and polymer combine a kind of excellent combination property obtained.
In the case of being not powered on, when i.e. light modulation film is in OFF state, the side through light modulation film looks over it is seen that the color of liquid crystal in light modulation film, looks over from opposite side, is the color of corresponding colourful transparent base material.In the case of energising, when i.e. light modulation film is in ON state, the transparent state of polymer liquid crystal color, and the color of colourful transparent base material does not has any change, therefore what difference is the color seen from light modulation film both sides do not have, i.e. see be all liquid crystal polymer carry out with the color of colourful transparent base material overlapping after the third color.
In this utility model embodiment, by controlling the color of colored transparent materials layer, can reach to reduce further the purpose of the OFF state transmitance of light modulation film.Under at powering-off state, the light transmittance of light modulation film is light transmittance during OFF state；On the other hand, when, in the case of energising, the light transmittance of light modulation film is light transmittance during ON state.If the light transmittance needing the OFF state of light modulation film is lower, colored light modulation base material can select color deeper colored light modulation base material.
The material of transparent substrate layer acts primarily as the effect supporting protection, and material is more difficult to find, it is not necessary to synthesize voluntarily, it is preferred that the first transparent substrate layer 3 and the second transparent substrate layer 7 use transparent polyethylene terephthalate (PET).
In this utility model embodiment, conductive layer can directly plating over the transparent substrate, the most widely used have nano indium tin metal conductive oxide layer, play after energising and make light modulation film become bright effect；I.e. first conductive layer 4 and the second conductive layer 6 plating respectively is in the first transparent substrate layer 3 and the second transparent substrate layer 7.Preferably, the first conductive layer 4 and the second conductive layer 6 use nano indium tin metal-oxide.
Above this utility model is described in detail, but this utility model is not limited to above-mentioned embodiment, in the ken that those of ordinary skill in the art are possessed, it is also possible to make a variety of changes on the premise of without departing from this utility model objective.Many other can be made without departing from spirit and scope of the present utility model to change and remodeling.Should be appreciated that this utility model is not limited to specific embodiment, scope of the present utility model is defined by the following claims.
