Description
Technical field
The invention belongs to field of application of liquid crystal, be specifically related to the application of a kind of liquid-crystal composition and this liquid-crystal composition.
Background technology
Since Austrian scientist Lai Nicier first time in 1888 has been synthesized liquid crystal, the real development of liquid crystal industry is the thing of nearly more than 30 years, because liquid crystal display material has obvious advantage, as driving voltage is low, power consumption is small, reliability is high, display contains much information, colored display, flicker free, flat pannel display etc. can be realized, liquid crystal monomer and liquid-crystal display all experienced by huge development, liquid crystal monomer has synthesized 10,000 plurality of liquid crystals materials at present, wherein conventional liquid crystal display material has thousands of kinds, classify by the center bridged bond of liquid crystal molecule and the feature of ring, mainly contain biphenyl liquid crystal, Santosol 360 liquid crystal, ester liquid crystal, alkynes class, difluoromethoxy bridge, ethane and heterocyclic etc.Liquid-crystal display also develops into TN-TFT, VA-TFT, IPS-TFT, PDLC etc. of present large color screen from TN, the STN of the black and white the small screen before 30 years.
Main novel liquid crystal display mode has optical compensation bending mode (OCB), coplanar transformation liquid-crystal display (IPS), vertical alignment mode (VA), rotational symmetry microstructure liquid-crystal display (ASM), the display of multidomain twisted liquid crystal etc.
The design of various display mode liquid crystal cell is different, type of drive is different, liquid crystal molecule director is different with glass substrate direction, optical compensation bending mode (OCB), coplanar transformation liquid-crystal display (IPS) liquid crystal molecule director are parallel with glass substrate direction, and vertical alignment mode (VA), rotational symmetry microstructure liquid-crystal display (ASM) is vertical with glass substrate direction without liquid crystal molecule director under electric field status.
The IPS of parallel arrangement mode, the dielectric anisotropy (△ ε) of liquid crystal both can be positive, also can be negative.
Vertical alignment mode (VA) all liquid crystal molecules are vertical with glass substrate direction when null field, with vertical incidence light ray parallel.When polaroid is orthogonal, can show good dark-state, so such device has good contrast gradient, the dielectric anisotropy (△ ε) using liquid crystal must be negative.The optical anisotropy (△ n) of liquid crystal, the thickness (d) of liquid crystal cell, the wavelength (λ) of incident light almost do not affect contrast gradient.The time of response of vertical alignment mode (VA) wants much shorter than meander configuration device, about being about half.Under applied voltages affect, the Bending Deformation of what VA device mainly produced is liquid crystal molecule, what ECB produced is the curved change of exhibition of liquid crystal molecule, and distortion display produces is the twist distortion of liquid crystal molecule, its time of response is also inversely proportional to bending, Zhan Qu, distortion elastic constant respectively, bend elastic constant due to most liquid crystal liquid crystal is in normal circumstances greater than the bent elastic constant of exhibition, and open up bent elastic constant and be greater than again distortion elastic constant, this is also VA response device time reason faster.
OLED adopts organic electro luminescent layer initiatively reflective as light source as a kind of emerging display format, panel can be made more frivolous simultaneously, can be reduced operating voltage simultaneously, and high temperature performance does not affect by the change of material.Its display black is purer simultaneously.But cause human eye directly to receive the stimulation of light source due to its active illuminating, long-time viewing can feel tired out, be unfavorable for health, and liquid crystal material well avoids light source irradiation eyes in liquid-crystal display, simultaneously by thinning backlight, its frivolous degree and OLED can be made to match in excellence or beauty with glass substrate, but due to the reason of liquid crystal material, impact by temperature is comparatively large, and simultaneously responsive to photo-thermal, process of alignment causes contrast gradient to be declined to become LCD short slab simultaneously
Cyclopropyl structure is applied to liquid crystalline cpd also has bibliographical information, but on the compounds property in document, defect is comparatively large, and such as structural stability is poor, viscosity is very large, synthesis difficulty is large, does not thus obtain practical application so far.
Summary of the invention
The invention provides a kind of liquid-crystal composition, by the component A containing cyclopropyl structure, and the B component of twin nuclei, realize at good low temperature intersolubility and low rotary viscosity, with the demand of high reliability aspect, simultaneously by two kinds of structure matchings, the degree of order of whole liquid crystal system is promoted, enhance the globality with liquid crystal arrangement, improve the uneven and light leak of display that liquid crystal panel easily produces in the fabrication process.
The invention provides a kind of liquid-crystal composition, described liquid-crystal composition comprises component A and B component, and described component A is made up of compound shown in one or more formula I, formula II and/or formula III,
