Description
Technical field
The present invention relates to a kind of liquid-crystal composition, relate in particular to a kind of nematic liquid crystal composition.Liquid-crystal composition of the present invention can be used for the fields such as varifocal liquid crystal lens (Liquid Crystal lens).
Background technology
1888, F.Reinitzer was measuring when melting points of organic compounds, find some compound after thawing through going through an opaque muddy state, in the middle of the liquid of this muddiness, there is mutually the phenomenon similar with crystal, and is called liquid crystal.20 century 70s are due to the development of large-scale integrated circuit and liquid crystal material, the application of liquid crystal aspect demonstration had breakthrough progress, utilize electrooptic effect and the unicircuit of twisted nematic liquid crystal to combine, be made into display device, realize the industrialization of liquid crystal material, this liquid crystal material is called twisted nematic liquid crystal and shows (TN-LCD) material, and its product is mainly used on Die elektrische Zeituhr and counter.The mid-80, succeeds in developing Super Twisted Nematic Liquid Crystal and shows (STN-LCD) material, and its product is mainly used on beeper, mobile telephone and notebook computer.1993, having grasped array in Japan drives after the production technology of liquid crystal display TFT-LCD, liquid-crystal display has started rapid development, lcd technology has become the main flow of technique of display now, liquid-crystal display is just illustrated in face of people with colourful form, its many products are because its excellent characteristic makes its pursuit that is just becoming fashion, and very powerful and exceedingly arrogant commodity in market.
The devices such as camera, mobile phone camera, the demonstration of 3D stereopsis, phase modulator, often utilize zoom lens by image zoom or dwindle imaging.Traditional zoom camera lens is provided with multiple mirror groups (lens group), by moving along optical axis direction between mirror group, to change spacing each other, thereby whole focal length is changed, but does not affect image-forming range.But this kind of camera lens need to be longer mirror group miles of relative movement, cause the mechanism volume of this focusing large, regulate slowly, focusing range is limited, expensive, device drives consumed energy large and easily damage etc.
For finding the method that substitutes mechanical focusing, and can change focal length on a large scale, prior art discloses a kind of liquid-crystal zoom lens that utilizes electric field to control focal length (Liquid Crystal lens), form special electric field by applying voltage on the electrode with circular hole, liquid crystal molecule in electric field is deflected, thereby light is played to the effect that disperses or assemble.It is actual is a kind of simulated optical element, can realize easily by apply different voltage between electrode the specific optical lens characteristic that we want.
Another prior art also discloses a kind of column liquid crystal lens grating that utilizes electric field to form lens, realize 3D stereo display, by etch strip transparent ITO electrode on transparent glass substrate, then on this electrode, apply different voltage and form electric field, liquid crystal molecule in electric field is deflected, thereby change incident direction of light, the variation of logical superpotential variation and number of electrodes simultaneously changes focal length and the pitch etc. of column liquid crystal lens grating.
For realizing the superiority of the more traditional column physical grating of column liquid crystal lens grating, need column liquid crystal lens grating under 60Hz, 120Hz or higher frequency, can freely switch, to this, need a kind of liquid-crystal composition with high speed response property.
Between each variable of, liquid-crystal composition relevant with the response performance of column liquid crystal lens grating, there is following relation:
Relational expression one:

Wherein, γ
1be rotary viscosity, d is thickness of liquid crystal layer, K
11be the bent elastic constant of exhibition, V is driving voltage, and Vth is threshold voltage.
Can find out from above-mentioned relation formula, by reducing the rotary viscosity of liquid-crystal composition or improving it and open up bent elastic constant, or reduce thickness of liquid crystal layer, can shorten its time of response.But if reduce rotary viscosity to improve the time of response, the elastic constant of liquid crystal and transformation temperature also will decline thereupon, and if elastic constant increases, threshold voltage and rotary viscosity will be tending towards increasing.Meanwhile, if reduce thickness of liquid crystal layer, the degree of birefringence of liquid-crystal composition will increase, and this can cause rotary viscosity to increase equally.Therefore,, for improving the time of response, it is minimum that the equilibrium relationship between these three influence factors must reduce to.
The stereo display column liquid crystal lens as 3D, according to lens calculation formula f=r
2/ (2 Δ nd), r represents 1/2 this lens pitch, Δ n represents the degree of birefringence of liquid crystal, d represents that the box of liquid crystal cell is thick, more specifically drawing needs degree of birefringence (Δ n) is greater than more than 0.25, needs less viscoelastic coefficient ratio, wider transformation temperature scope simultaneously.
(Δ is n) an important physical property of liquid crystalline cpd to degree of birefringence.Double refraction is subject to benzene ring structure and the domination of π key end group in liquid crystal molecule to a great extent, therefore, it is relevant with the dielectric anisotropy of molecule that this character is actually, and the molecule with large dielectric anisotropy often also has large Δ n, but also have the situation of exception to exist.In the composition of homologous series compound composition, Δ n is usually linear with the concentration of component.Therefore generally all there is larger optical anisotropy containing the liquid crystal of isothiocyano, cyano group, ester group, alkoxyl group, phenyl ring or acetylene bond.Common TN, STN shows with the Δ n of mixed liquid crystal material generally between 0.12 to 0.20, TFT shows with the Δ n of liquid crystal material generally between 0.065 to 0.135, PDLC and multistable demonstration generally need to be greater than 0.20 with the Δ n of liquid crystal material, and the Δ n of 3D liquid crystal material of liquid crystal lens (Liquid Crystal lens) for stereo display is generally greater than 0.25.
Because the physicals of the each component of mixed liquid crystal material is each different, be therefore difficult to the parameters combination of realizing ideal, need to monomer liquid crystal select and component proportion aspect do further optimization.
