Description
Technical field
The present invention relates to display technique field, particularly relate to method for making and the structure thereof of the adjustable public advertising display screen of a kind of mist degree.
Background technology
The backlight module that liquid crystal display (LiquidCrystalDisplay, LCD) comprises housing, is located at the liquid crystal panel in housing and is located in housing.Usual liquid crystal panel is by a colored filter substrate (ColorFilter, CF) liquid crystal layer (LiquidCrystalLayer) that, a thin-film transistor array base-plate (ThinFilmTransistorArraySubstrate, TFTArraySubstrate) and is filled between two substrates formed.The relative inner of CF substrate and TFT substrate is provided with transparency electrode.Liquid crystal display is controlled by the orientation of electric field to liquid crystal molecule, changes polarisation of light state, and realizes penetrating and stop of light path by Polarizer, reach the object of display.
Active TFT-LCD display device obtains development at full speed in recent years and applies widely, can say, is big-and-middle undersized display no matter current, all by TFT-LCD in occupation of absolute market.And in current LCD application market, the terminal display screen that can be used for the public place that megastore, supermarket, hotel lobby, movie theatre, education, medical treatment and other stream of people collect obtains increasing demand and application, and just with annual more than 30% speed increment.Namely such public advertising display screen has common feature: dust and moisture, dispel the heat outstanding, low in energy consumption, wide viewing angle, high brightness and have certain anti-dazzle antireflecting function.Based on the singularity of public advertising display screen service condition, as the factor such as view and admire distant, ambient light is stronger, its antireflection and anti-dazzle function seem outbalance.Prior art can by carrying out surface treatment to Polarizer, make public advertising display screen have certain mist degree (Haze), to play out of doors or antireflection and anti-dazzle effect under indoor bright light usually.At present, the mist degree that public advertising display screen is conventional is in the industry generally about 44%, and the Polarizer handled well is with after LCD laminating, and mist degree is non-adjustable, cause the service condition of existing public advertising display screen limited, environmentally light intensity change can not carry out mist degree adjustment.
On the other hand, polymer-dispersed liquid crystal (PolymerDispersedLiquidCrystal, PDLC) as liquid crystal light modulation valve, in recent years by extensive concern and use.Low molecular weight liquid crystal mixes with prepolymer by PDLC mutually, under certain condition through polyreaction, forming micron-sized liquid crystal droplet is evenly dispersed in high molecular polymer network, the dielectric anisotropy of recycling liquid crystal molecule obtains has the material of electro-optic response characteristic, and it to operate mainly between scattering states and clear state and has certain gray scale.PDLC liquid crystal display has lot of advantages, such as do not need polaroid and oriented layer, preparation technology is simple, is easy to make large area flexible display etc., in optical modulator, temperature-sensitive and pressure-sensitive device, automatically controlled glass, light valve, Projection Display, e-book etc., obtains application at present.
The principle of work of PDLC liquid crystal display is: without impressed voltage when, intermembranously can not form regular electric field, and the direction of optic axis of liquid crystal particle is random, presents disordered state, its effective refractive index not with the index matching of polymkeric substance.Incident ray is by strong scattering, and film is opaque or translucent; When being applied with external voltage, the optical axis of liquid crystal particle arranges perpendicular to film surface, namely consistent with direction of an electric field, the effective refractive index of liquid crystal particle mates substantially with the refractive index of polymkeric substance, without obvious interface, constitute a basic uniform medium, can not there is scattering in incident light, the transparent shape of film.Therefore, under the driving of extra electric field, PDLC possesses switch feature, and its transparency also can improve along with executing alive increase.
