Description
Technical field
The present invention relates to liquid crystal material and its application fields, and in particular to a kind of containing fluoro terphenyl structure compound
Liquid-crystal composition and its application.
Background technique
Currently, liquid crystal is widely applied in field of information display, while the application in optical communication also achieves one
Fixed progress (S.T.Wu, D.K.Yang.Reflective Liquid Crystal Displays.Wiley, 2001).It is close several
Year, the application field of liquid-crystal compounds significantly widens kinds of displays part, electro-optical device, electronic component, sensor etc.,
Nematic liquid crystal compound obtains most commonly used application in flat-panel monitor, especially for tft active matrix
In system.
Liquid crystal display experienced very long road for development with the discovery of liquid crystal.Austrian botanist in 1888
Friedrich Reinitzer has found the first liquid crystal material benzoic acid cholesterol (cholesteryl benzoate).
Manguin has invented rubbing within 1917, to make single domain liquid crystal and research optical anisotropy.E.Bose in 1909
Moving (Swarm) theory is established, and (1918) are supported in the experiment for obtaining L.S.Ormstein and F.Zernike et al., after
Statistical fluctuation is discussed as through De Gennes.G.W.Oseen and H.Zocher was obtained in foundation continuum theory in 1933
F.C.Frank perfect (1958).M.Born (1916) and K.Lichtennecker (nineteen twenty-six) has found and has studied liquid crystal
Dielectric anisotropy.1932, nematic phase was divided into positive and negative property two major classes accordingly by W.Kast.Nineteen twenty-seven,
V.Freedericksz and V.Zolinao discovery nematic liquid crystal is under electric field or magnetic fields, and deformation occurs and there are voltages
Threshold value (Freederichsz transformation).This production for being found to be liquid crystal display provides foundation.
Nineteen sixty-eight RCA Corp., U.S. R.Williams discovery nematic liquid crystal forms striped farmland under electric field action, and has
Light scattering phenomenon.With dynamic scattering display pattern is developed into and first liquid crystal in the world is made in G.H.Heilmeir
Display (LCD).Early seventies, Helfrich and Schadt have invented TN principle, and people are using TN photoelectric effect and integrate
Circuit combines, and is made into display device (TN-LCD), has opened up wide prospect for the application of liquid crystal.The seventies with
Come, due to the development of large scale integrated circuit and liquid crystal material, application of the liquid crystal in terms of display achieves breakthrough development,
1983~1985 years T.Scheffer et al. successively propose super-twist nematic (Super Twisred Nematic:STN) mode
And active matrix (Active matrix:AM) mode that P.Brody was proposed in 1972 is used again.Traditional TN-
LCD technology has developed into STN-LCD and TFT-LCD technology, although the number of scanning lines of STN up to 768 rows more than, work as temperature
The problems such as response speed, visual angle and gray scale are remained when raising, therefore large area, high information quantity, colored display are mostly
Using Active Matrix LCD At mode.TFT-LCD is widely used for direct viewing type TV, large-curtain projecting TV set, terminal
Display and certain military instrument are shown, it is believed that TFT-LCD technology has more extensive application prospect.
Wherein " active matrix " includes two types: 1, the OMS on the silicon wafer as substrate (partly lead by metal oxide
Body) or other diodes.2, the thin film transistor (TFT) on the glass plate as substrate (TFT).
Monocrystalline silicon limits display size as substrate material, because each section display device even module assembled is in its knot
Occur many problems at conjunction.Thus, second of thin film transistor (TFT) is the promising active matrix type of tool, the photoelectricity effect utilized
It should be usually TN effect.TFT includes compound semiconductor, such as Cdse, or the TFT based on polycrystalline or amorphous silicon.
Currently, LCD product technology is mature, the technologies such as visual angle, resolution ratio, color saturation and brightness are successfully solved
Problem, display performance already close to or be more than CRT monitor.Large scale and small-medium size LCD respective field gradually
Occupy the dominant position of flat-panel monitor.But (viscosity is high) is restricted by liquid crystal material itself, cause the response time to become shadow
Ring the principal element of Performance Monitor.
Specifically, the response time of liquid crystal is limited to the rotary viscosity γ 1 and elastic constant of liquid crystal, liquid crystal group is reduced
It closes the rotary viscosity of object and promotes elastic constant for the response time of reduction liquid crystal display, accelerate the response of liquid crystal display
Speed has significant effect.
