Description

A kind of liquid-crystal composition with high permeability and its application

Technical field

The present invention relates to a kind of liquid-crystal composition, belong to liquid crystal display material field, more particularly to a kind of liquid-crystal composition with high permeability and its Using.

Background technology

At present, liquid crystal is used widely in field of information display, at the same the application in optical communication also make some progress (S.T.Wu, D.K.Yang.Reflective Liquid Crystal Displays.Wiley, 2001).In recent years, the application of liquid-crystal compoundss was significantly widened Kinds of displays part, electro-optical device, electronic component, sensor etc..For this purpose, many different structures are had been proposed that, particularly in nematic crystal Field, nematic liquid crystal compound have obtained most commonly used application so far in flat faced display.Particularly it is used for the system of tft active matrix In.

Liquid crystal display experienced very long road for development with the discovery of liquid crystal.Austria botanist Friedrich Reinitzer are found that within 1888 A kind of liquid crystal material benzoic acid cholesterol (cholesteryl benzoate).Manguin has invented rubbing within 1917, to make single domain liquid Brilliant and research optical anisotropy.E.Bose in 1909 is established and is collected together (Swarm) theory, and obtains L.S.Ormstein and F.Zernike etc. (1918) are supported in the experiment of people, are discussed as statistical fluctuation by De Gennes.G.W.Oseen and H.Zocher1933 foundes continuum Theory, and obtain F.C.Frank perfect (1958).M.Born (1916) and K.Lichtennecker (nineteen twenty-six) have found and have studied liquid crystal Dielectric anisotropy.1932, nematic phase was divided into positive and negative two big class of property by W.Kast accordingly.Nineteen twenty-seven, V.Freedericksz and V.Zolinao It was found that nematic liquid crystal deforms upon and exists voltage threshold (Freederichsz transformations) under electric field (or magnetic field) effect.This is found to be liquid crystal The making of display provides foundation.

Nineteen sixty-eight RCA Corp. of U.S. R.Williams has found that nematic liquid crystal forms striped farmland under electric field action, and has light scattering phenomenon. G.H.Heilmeir with will its develop into dynamic scattering display pattern, and make first liquid crystal display (LCD) in the world.Early seventies, Helfrich and Schadt have invented TN principles, and people are combined using TN photoelectric effect and integrated circuit, are made display device (TN-LCD) it is, that wide prospect has been opened up in the application of liquid crystal.Since the seventies, due to the development of large scale integrated circuit and liquid crystal material, liquid The brilliant application in terms of display achieves breakthrough development, and 1983～1985 years T.Scheffer et al. successively propose super-twist nematic (Super TwisredNematic：STN) active matrix (the Active matrix that pattern and P.Brody were proposed in 1972：AM) mode is adopted again With.Traditional TN-LCD technologies have developed into STN-LCD and TFT-LCD technologies, although the number of scanning lines of STN up to 768 rows more than, But the problems such as remaining response speed, visual angle and gray scale when the temperature increases, therefore large area, high information quantity, colored display adopted mostly Use Active Matrix LCD At mode.TFT-LCD is widely used for that direct viewing type TV, large-curtain projecting TV set, terminal show and some are military Instrument shows, it is believed that TFT-LCD technologies have more wide application prospect.

Wherein " active matrix " is including two types：1st, on the silicon wafer as substrate OMS (metal-oxide semiconductor (MOS)) or other diodes. 2nd, on the glass plate as substrate thin film transistor (TFT) (TFT).

Monocrystal silicon limits display size as substrate material, because each several part display device even module assembled many problems occurs in its junction. Thus, second thin film transistor (TFT) is that have promising active matrix type, and the photoelectric effect for being utilized is typically TN effects.TFT includes chemical combination Thing quasiconductor, such as Cdse, or the TFT based on polycrystalline or amorphous silicon.

At present, for small size and middle display of size for flat board and smart mobile phone display, (IPS) and fringing field switching (FFS) in face, are changed Pattern is very interesting.The reason for IPS and FFS mode are widely used in intelligent and middle display of size is wide viewing angle, relative to existing The low operational factor of pattern is known in technology, relative to IPS patterns, FFS possesses higher absorbance.Liquid crystal compound feature of the prior art exists It is made up of the compound with positive dielectric anisotropy and optional neutral compound in which.

In a liquid crystal display, expect to contribute to the medium of the following advantage in box：

1st, wide nematic phase range (particularly downwards until low temperature)

2nd, the ability (outdoor application, automobile, avionics) for switching under extremely low temperature

3rd, the toleration (longer service life) to ultraviolet radioactive for improving

4th, low threshold voltage (saving electric energy)

5th, high-transmission rate.

The major function of liquid crystal display is to play a part of photoswitch, light after liquid crystal layer light loss to only original 6% or so, so will Obtain brighter display effect, it is necessary to increase backlight illumination, this will increase the energy consumption of backlight and reduce backlight life.Another approach is to obtain The liquid crystal display of high absorbance, liquid-crystal composition provided by the present invention are conducive to the absorbance for improving liquid crystal display.

It has now been discovered that under IPS and FFS display patterns, with little ε_∥/ε_⊥Liquid-crystal composition can effectively lift the transmission of liquid crystal display Rate characteristic, and the liquid crystal display of low driving voltage requires that liquid crystal has big Δ ε (ε_∥-ε_⊥), therefore, lift ε_⊥Become lifting liquid crystal display The key factor of transmitance.In liquid-crystal composition, how to choose liquid crystal molecule becomes this in the big liquid-crystal compoundss of the dielectric perpendicular to long axis direction Item index is more of paramount importance.

In view of this, it is special to propose the present invention.

The content of the invention

The first object of the present invention is to provide a kind of liquid-crystal composition with high permeability, and the liquid-crystal composition obtained by the present invention is effectively lifted The vertical dielectric of liquid-crystal composition, effectively improves the light transmission rate of liquid crystal display.And the rotary viscosity γ 1 of very low numerical value, big bullet Property constant, the various applications of fast response speed, it is adaptable to TN, IPS and FFS mode, particularly IPS and FFS mode.
