Abstract
The utility model discloses a holographic liquid crystal display, which comprises a piece of liquid crystal, a polarizer, an analyzer and a reflection shield. The holographic liquid crystal display is characterized in that the reflection shield is a holographic reflector, and transparent adhesive is arranged between the holographic reflector and the analyzer. The holographic reflector can be a holographic reflector wit a uniformly bright background so as to brighten the images and strengthen the contrast ratio of the liquid crystal, and can also be a holographic reflector with three-dimensional holographic images, so that the display of the liquid crystal can be diversified and interesting, and the utility model can also has the function of anti-counterfeiting.
Description
The utility model relates to a kind of holographic LCD.
Common liquid crystals shows for realizing reflection at present, generally pastes a kind of radiation shield with diffusing characteristic diffuser at the liquid crystal back side.Thereby like this since liquid crystal polarizer to the decay of light make show dim, poor contrast.Display image is single two dimensional image in addition, can not show the 3D hologram figure.
The purpose of this utility model is the above-mentioned shortcoming that overcomes prior art, and a kind of holographic LCD is provided, and image is bright, contrast is strong.
To achieve these goals, the utility model provides a kind of holographic LCD, comprises liquid crystal, the polarizer, analyzer and radiation shield, it is characterized in that: used radiation shield is a holographic reflector, between this holographic reflector and analyzer transparent adhesive tape is arranged.
Owing to adopt such scheme, when holographic reflector during by ambient light illumination, will be in the specific direction scope diffraction go out hologram image than high several times of common radiation shield brightness.Can improve liquid crystal display contrast and brightness like this.In addition, owing to can form the background of liquid crystal display according to the corresponding three-dimensional hologram of the production of different brands, thus make liquid crystal display variation, interest and appeal, also can have anti-fake effect concurrently in such cases.
The utility model is done to carry out the explanation in a step below in conjunction with accompanying drawing and example:
Fig. 1 is this utility model synoptic diagram.
Fig. 2 takes the light path layout for main hologram.
Fig. 3 duplicates light path layout figure for reflection hologram.
Fig. 4 takes synoptic diagram for the logical master hologram of penetrating.
As shown in Figure 1, be respectively polarizer P1 and analyzer P2 in the front and back of liquid crystal LC, realize liquid crystal display thereby the variable voltage electrode is added in the polarization characteristic that can change liquid crystal on the liquid crystal LC.Holographic reflector HR (can be the transmission hologram or the photopolymer reflection hologram in plating reflection horizon) is sticked on the analyzer P2 with transparent adhesive tape G, when ambient light L shines on the hologram by liquid crystal display, hologram will go out holographic images than strong several times of common diffuse reflection along a coning angle θ diffraction.Thereby human eye E can see light ground or holographic images on the liquid crystal display in this scope the time, to reach the purpose of improving liquid crystal word effect.In addition, this holographic reflector also can form the background of liquid crystal display according to the corresponding three-dimensional hologram of the production of different brands, thereby make liquid crystal display variation, interest and appeal, be useful for all kinds of liquid crystal display products such as mobile phone, game machine, BB machine, laptop computer, e-commerce.
Fig. 2 is the shooting light path of the main hologram H1 of production liquid crystal reflectors, the size of H1 has determined the viewing angle θ of hologram, laser beam L1 is divided into object beam and participate-reform light beam by beam splitter BS, object beam is by mirror M 1 pinhole filter SF1 and collimation lens CL1 back lighting target subject O, through shining after the scattering on the main hologram H1, when if target subject O is the object of diffusion type, then object beam passes through mirror M 3 along the dotted line light path after mirror M 1, shines on the target subject O behind the pin hole wave-wave device SF3.The participate-reform light beam is by mirror M 2, pinhole filter SF2 and collimation lens CL2, with the H1 angle be that the directional lights of 45 degree are directly according to penetrating main hologram H1.Can produce needed holographic reflector effect with this light path.When only needing a holographic reflector to produce even bright background, object O is that simple frosted glass or diffuse reflection are shielded in vain, the size of its area has determined the size of holographic reflector, when the needs holographic reflector produces 3D pattern or other word content, can in conjunction with the real dotted line layout in the light path and on main hologram H1 subregion or repeat multiexposure, multiple exposure and produce various needed hologram images.
Fig. 3 is that reflection hologram duplicates index path, and it is to make reflection hologram with the photo-induced polymer holographic recording medium.Laser beam L1 is divided into object beam and participate-reform light beam by beam splitter BS2, wherein object beam is by mirror M 21, pinhole filter SF21, and behind the collimation lens CL21 with directional light the opposite direction irradiation main hologram H1 during from as shown in Figure 1 recorded hologram, promptly conjugation is reproduced.The photo-induced polymer holographic recording medium is placed on the recording reflection holography figure H2 of conjugation real image place of main hologram H1.Participate-reform light is by mirror M 22, and pinhole filter SF22, collimation lens CL22 have formed the striated structure of refraction back modulation like this from the reverse side recorded hologram of reflection hologram H2 in hologram H2 inside, will reveal bright holographic images again when rayed.Because photopolymer can be the package film, thereby can add automatic unwinding device U and automatic winding device R in light path, then can realize continuous optical reproduction.With this reflection hologram with transparent gluing card after analyzer P2 goes up, just formed final holographic finished LCD products.The method is to utilize the principle of reflection hologram to take and duplicate, and promptly makes reflection hologram on the photo-induced polymer holographic recording medium.Because the Bragg effect of reflection hologram is only carried out diffraction to specific wavelength, thereby this hologram can only show filtergram, is not suitable for Color Liquid Crystal Display, production lot is limited, but brightness is fine, and in the viewing angle of no holographic images, its background patterns is similar with common radiation shield.
Fig. 4 is that the transmission hologram mother matrix is taken synoptic diagram, and it is to make transmission-type hologram with the embossed holographic copy mode.Laser beam L1 is divided into thing light and participate-reform light by beam splitter BS3, and object beam reproduces main hologram H1 with the directional light conjugation by SF31 behind the CL31.At the record photoresist transmission hologram H3 of the conjugation real image place of H1.Participate-reform light is by mirror M 31, and pinhole filter SF32 is behind the collimation lens CL32, from the positive incident recorded hologram of transmission hologram H3.Will form the interference fringe of relief type like this on hologram H3 surface, this striped through chemical silvering, behind the precise electrotyping nickel, has just been formed the mold pressing mother matrix.With this piece mother matrix, rout up working version through electroforming again and just can on the plastic foil in plating reflection horizon, batch hot pressing duplicate.Again this holographic reflector is pasted on transparent adhesive tape and just forms final holographic finished LCD products after analyzer P2 goes up.The method is to utilize the principle of transmission hologram to take hologram, then formation of hologram is become the metallic nickel version and aluminize or the plastic foil (as PET) in other reflection horizon on be similar to common holographic trademark the mode of production carry out moulding replication.Because there is not the Bragg effect in the plane transmission hologram, can make hologram reconstruction white picture from light path design, thereby can be used for Color Liquid Crystal Display, make it more Bai Gengliang.
