Description

Liquid-crystal composition

Technical field

The present invention relates to field of liquid crystal display, and in particular to a kind of liquid-crystal composition and the liquid crystal comprising the liquid-crystal composition Display element or liquid crystal display.

Background technology

Currently, the application range expansion of liquid-crystal compounds is increasingly wider, a plurality of types of displays, electricity can be applied to In optical device, sensor etc..The type of liquid-crystal compounds for above-mentioned display field is various, and wherein nematic liquid crystal is using most It is extensive.Nematic liquid crystal has been applied in passive TN, STN matrix display and system with tft active matrix.

For thin-film transistor technologies (TFT-LCD) application field, although market is very huge in recent years, technology It is gradually ripe, but requirement of the people to display technology is also constantly improving, and is especially realizing quick response, reduces driving electricity Pressure is to reduce power consumption etc..The liquid crystal material photoelectron material one of important as liquid crystal display, to improving liquid crystal display The performance of device plays an important role.

As liquid crystal material it is necessary to have good chemically and thermally stability and to the stabilization of electric field and electromagnetic radiation Property.And as thin-film transistor technologies (TFT-LCD) liquid crystal material, it does not need only to have as outside upward stability, should also have Wider nematic temperature range, suitable birefringence anisotropy, very high resistivity, good uviolresistance The performances such as energy, high charge conservation rate and low-steam pressure.

Dynamic menu is shown and is applied, eliminates and shows picture ghost and hangover, it is desirable that liquid crystal has response speed quickly Degree, therefore it is required that liquid crystal has lower rotary viscosity γ₁；In addition, for portable device, in order to reduce equipment energy consumption, wish Hope the driving voltage of liquid crystal as low as possible；And for the display of the purposes such as TV, the driving voltage requirement for liquid crystal It is not so low.

The viscosity of liquid-crystal compounds, especially rotary viscosity γ₁The response time after liquid crystal power-up is directly affected, either Rise time (t_on) or fall time (t_off), all with the rotary viscosity γ of liquid crystal₁It is proportional, rise time (t_on) by In related with liquid crystal cell and driving voltage, can be adjusted with reduction liquid crystal cell box thickness by the method for increasing driving voltage；And Fall time (t_off), mainly with the elastic constant of liquid crystal with liquid crystal cell box thickness related, the decline of box thickness unrelated with driving voltage (t can be reduced fall time_off), and under different display modes, the motion mode of liquid crystal molecule is different, tri- kinds of moulds of TN, IPS, VA Formula respectively with average elastic constants K, distortion elastic constant, bend elastic constant inversely.

According to liquid crystal continuum theory, after a variety of different liquid crystal deform upon under external force (electric field, magnetic field) effect, meeting By intermolecular interaction, original shape is returned in meeting " rebound "；Likewise, liquid crystal is also due to intermolecular interaction Power forms " viscosity ".The minor change of liquid crystal molecule can make the conventional parameter performance of liquid crystal that apparent variation occur, these variations Has plenty of certain rule, some seems to be not easy to find rule, and the interaction between liquid crystal molecule also will produce obviously Influence, these influences are very delicate, so far also without forming very perfect theoretical explanation.

The viscosity of liquid crystal is related with liquid crystal molecule structure, studies the viscosity and liquid of the liquid crystal system that different liquid crystal molecules are formed Relationship between brilliant molecular structure is one of the vital task of dispensing liquid crystal engineer.
