Description
Technical field
The present invention relates to field of liquid crystal display, be specifically related to a kind of liquid-crystal composition and comprise liquid crystal display device or the liquid-crystal display of this liquid-crystal composition.
Background technology
At present, it is more and more wider that the range of application of liquid crystalline cpd is expanded, and it can be applicable in polytype indicating meter, electro-optical device, sensor.For liquid crystalline cpd of a great variety in above-mentioned display field, wherein nematic liquid crystal is most widely used.Nematic liquid crystal has been applied in passive TN, STN matrix display and has had in the system of tft active matrix.
For thin-film transistor technologies (TFT-LCD) Application Areas, although market is very huge in recent years, technology is also ripe gradually, people to the requirement of technique of display also in continuous raising, especially in realization response fast, driving voltage is reduced to reduce the aspects such as power consumption.Liquid crystal material as one of important photoelectron material of liquid-crystal display, the effect important to the performance improving liquid-crystal display.
As liquid crystal material, need to have good chemistry and thermostability and the stability to electric field and electromagnetic radiation.And as thin-film transistor technologies (TFT-LCD) liquid crystal material, not only need to have as outside upward stability, also should have the performances such as wider nematic temperature range, suitable degree of birefringence anisotropy, very high resistivity, good anti-ultraviolet property, high electric charge conservation rate and low-steam pressure.
For dynamic menu display application, eliminate display frame ghost and hangover, require that liquid crystal has very fast response speed, therefore require that liquid crystal has lower rotary viscosity γ
1; In addition, for handheld device, in order to reduce equipment energy consumption, wish that the driving voltage of liquid crystal is low as far as possible; And for the indicating meter of the purposes such as TV, the driving voltage for liquid crystal requires it is not so low.
The viscosity of liquid crystalline cpd, especially rotary viscosity γ
1direct affect liquid crystal power up after time of response, no matter be rise time (t
on) or fall time (t
off), all with the rotary viscosity γ of liquid crystal
1proportional, rise time (t
on) due to relevant with liquid crystal cell and driving voltage, can be regulated with reduction liquid crystal cell box is thick by the method strengthening driving voltage; And fall time (t
off) have nothing to do with driving voltage, mainly thick relevant with liquid crystal cell box with the elastic constant of liquid crystal, the decline that box is thick can reduce fall time (t
off), and under different display modes, the mode of motion of liquid crystal molecule is different, TN, IPS, VA Three models respectively with average elastic constants K, distortion elastic constant, bend elastic constant inversely.
According to liquid crystal continuum theory, after there is deformation in various different liquid crystal under external force (electric field, magnetic field) effect, can by intermolecular interaction, original shape is returned in meeting " resilience "; Same, liquid crystal is also because intermolecular interaction force forms " viscosity ".The subtle change of liquid crystal molecule, can make the conventional parameter performance of liquid crystal that significantly change occurs, these changes have plenty of certain rule, seeming of having not easily finds rule, also obvious impact can be produced for the interaction between liquid crystal molecule, these impacts are very delicate, also do not form very perfect theoretical explanation so far.
The viscosity of liquid crystal is relevant with liquid crystal molecule structure, and the relation studied between the viscosity of the liquid crystal system that different liquid crystal molecule is formed and liquid crystal molecule structure is one of vital task of dispensing liquid crystal slip-stick artist.
