Description
Technical field
The present invention relates to a kind of liquid-crystal composition being applied to liquid crystal display device, be particularly applied to the liquid-crystal composition of liquid crystal display device and the application in electrooptics liquid-crystal display thereof of the in-plane switching mode (IPS) that active-matrix mode drives.
Background technology
Liquid crystal display device be utilize liquid crystal material itself to possess optical anisotropy and dielectric anisotropy to carry out work, be widely used at present.The characteristic utilizing liquid crystal material different and mode of operation, various different operating mode can be designed device to, what wherein conventional display generally used has TN pattern (twistnematic, twisted nematic mode), STN pattern (supertwistednematic, supertwisted nematic mode), ecb mode (electricallycontrolled birefringence, electrically controlled birefringence mode), ocb mode (opticallycompensatedbend, optical compensation bending mode), IPS pattern (in-planeswitching, in-plane switching mode), VA pattern (verticalalignment, vertical alignment mode) etc.
In Poor information, the general passive mode that adopts drives, but along with the increasing of quantity of information, increasing of display size and display way, crosstalk and contrast gradient reduce phenomenon and become serious, therefore generally adopt active matrix (AM) mode to drive.In AM-TFT element, the addressing in two-dimensional grid of TFT switch device, charges to pixel electrode, becomes off condition again afterwards in the finite time being in conducting, until addressed again in next cycle.Therefore, between two addressing periods, do not wish that the voltage on pixel changes, otherwise the transmittance of pixel can change, cause the instability shown.The velocity of discharge of pixel depends on the resistivity of electrode capacity and inter-electrode dielectric.Therefore require that liquid crystal material has higher resistivity, require that material has suitable optical anisotropy △ n(△ n value generally between 0.08-0.15 simultaneously), and lower threshold voltage, to reach reduction driving voltage, reduce the object of power consumption; Also require that there is lower viscosity, to meet the needs of response fast.
The beginning of the seventies in last century, experimental research is carried out to basic electro-optical characteristic that is evenly distributed, aligned twisted and nematic liquid crystal IPS pattern, be characterized in that pair of electrodes makes on the same substrate, and another substrate there is no electrode, controlling the arrangement of liquid crystal molecule by being added in this interelectrode transverse electric field, this pattern therefore also can be claimed to be transverse field pattern.Nematic liquid crystal molecules uniform parallel arrangement between two substrates in IPS pattern, the orthogonal placement of two polaroids.IPS pattern is when not added electric field, and incident light is blocked by two orthogonal polaroids and in dark-state, during added electric field, liquid crystal molecule rotates and causes delay, so there is light to spill from two orthogonal polaroids.
Because IPS pattern making is simple and have very wide visual angle, thus they become can improve viewing angle characteristic and realized the most attractive way of large-area displays.
In-plane switching mode (i.e. IPS pattern) only needs linear polarizer and does not need compensate film, and just its response speed is too slow, can not show the picture of rapid movement.Therefore relative to traditional TN-TFT type display format, IPS type display liquid crystal demand response speed faster.
But, based on the complicacy of liquid crystal mixed crystal modulation, consider from the angle of liquid-crystal composition material modulation, various aspects of performance (the low optical anisotropy value of material, high dielectric anisotropy value, high resistivity, low rotary viscosity, low fusing point, high clearing point, good thermostability and ultraviolet stability etc.) between mutually pin down, improve performance on the one hand often along with the reduction of another aspect performance, the liquid-crystal composition that modulation various aspects of performance is all suitable is often very difficult.
In prior art, in in-plane switching mode (i.e. IPS pattern), liquid crystal material is subject to the disturbance of temperature, generation light is at random, and then causes the problem of dark-state light leak, contrast gradient deficiency, as document " the review prospect of coplanar switching liquid crystal display panel technology development " etc.There is the problems such as response speed is inadequate, driving voltage is high, aperture opening ratio is low simultaneously.
The electric field controlling Liquid Crystal Molecules Alignment state under IPS pattern is applied by respective electrode on hypocoxa; Because the distance between adjacent electrode is larger than the upper lower glass substrate of general T N mode liquid crystal box, this just causes the strength of electric field under same drive voltage between two electrodes relatively weak (compared with general T N pattern), and its result is exactly that response speed is slack-off.To improve response speed, just must strengthen driving voltage, thus power consumption is increased.
Therefore, need a kind of liquid-crystal composition badly, this liquid-crystal composition needs to have distortion elastic constant K
22the material that value is larger reduces the essential dark-state light leak of IPS when room temperature, or adopts optimized liquid crystal cell retardation to promote contrast gradient, thus makes in-plane switching mode (i.e. IPS pattern) have more black dark-state, and the characteristic of higher contrast gradient.Said composition can realize fast-response simultaneously, possesses low rotary viscosity, suitably high optical anisotropy, high dielectric anisotropy, the performances such as good thermostability and ultraviolet stability.
Summary of the invention
Goal of the invention: the object of this invention is to provide a kind of liquid-crystal composition being applicable to the IPS pattern of active matrix, said composition can while realizing fast-response, possesses suitably high optical anisotropy, there is the liquid crystal material of less rotational viscosity and larger dielectric anisotropy, shorten making the time of response (rise time and fall time) of indicating meter further and driving voltage reduction, thus can power consumption be reduced, there is the performances such as good thermostability and ultraviolet stability simultaneously.
