Description
Technical field
The invention belongs to liquid crystal material technical field, more particularly to a kind of negative dielectric anisotropy liquid crystal composition and its application.
Background technology
At present, liquid crystal is widely applied in field of information display, while the application in optical communication also makes some progress (S.T.Wu, D.K.Yang.Reflective Liquid Crystal Displays.Wiley, 2001).In recent years, 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, particularly in the system of tft active matrix.
Liquid crystal display experienced very long road for development with the discovery of liquid crystal.Austria botanist Friedrich Reinitzer are found that the first liquid crystal material benzoic acid cholesterol (cholesteryl benzoate) within 1888.Manguin has invented rubbing within 1917, to make single domain liquid crystal and research optical anisotropy.E.Bose in 1909 establishes moving (Swarm) theory, and obtains L.S.Ormstein and F.Zernike et al. experiment support (1918), and statistical fluctuation is discussed as by De Gennes.G.W.Oseen and H.Zocher founded continuum theory in 1933, and obtained F.C.Frank perfect (1958).M.Born (1916) and K.Lichtennecker (nineteen twenty-six) has found and have studied the dielectric anisotropy of liquid crystal.1932, nematic phase was divided into the positive and negative major class of property two by W.Kast accordingly.Nineteen twenty-seven, V.Freedericksz and V.Zolinao have found that nematic liquid crystal under electric field or magnetic fields, deforms upon and there is voltage threshold (Freederichsz transformations).This making for being found to be liquid crystal 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.With dynamic scattering display pattern is developed into and first liquid crystal display (LCD) in the world is made in G.H.Heilmeir.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), are 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, application of the liquid crystal in terms of display achieves breakthrough development, and 1983~1985 years T.Scheffer et al. successively propose super-twist nematic (Super Twisred Nematic：STN) active matrix (the Active matrix that pattern and P.Brody were proposed in 1972：AM) mode is used again.Traditional TN-LCD technologies have developed into STN-LCD and TFT-LCD technologies, although STN number of scanning lines up to 768 rows more than, but the problems such as remain response speed, visual angle and gray scale when the temperature increases, therefore large area, high information quantity, colored display use Active Matrix LCD At mode mostly.TFT-LCD is widely used for that direct viewing type TV, large-curtain projecting TV set, terminal are shown and some military instrument are shown, it is believed that TFT-LCD technologies have more wide application prospect.
Wherein " active matrix " includes 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).
Monocrystalline silicon limits display size as substrate material, because each several part display device even module assembled many problems occurs in its junction.Thus, second of thin film transistor (TFT) is the promising active matrix type of tool, and the photoelectric effect utilized is typically TN effects.TFT includes compound semiconductor, such as Cdse, or the TFT based on polycrystalline or amorphous silicon.
Current large scale TV classes liquid crystal display is main based on VA (vertical arrangement) patterns and FFS (fringing field effect) pattern, VA class displays have very excellent contrast performance, it is highly profitable for the display effect for lifting liquid crystal display, and current VA class display technologies have been mature on the whole, but its response time problem run into hampers the progress of Display Technique always.
