Description
Technical field
The present invention relates to a kind of big dielectric, low-power consumption, fast-response, high stability liquid-crystal composition, and the liquid comprising the liquid-crystal composition
LCD.
Background technology
Various fields in presentation of information used for liquid crystal display device, can be used for straight watching display and are also used for projection type display.
Type according to display pattern is divided into PC (phase change, phase transformation), TN (twist nematic, twisted-nematic), STN (super twisted
Nematic, super twisted nematic), ECB (electrically controlled birefringence, electrically conerolled birefringence), OCB (optically compensated
It is bend, optical compensation curved), IPS (in-plane switching, coplanar transformation), the type such as VA (vertical alignment, vertical orientation).
It is operated in TN, the element of STN mode uses positive dielectric anisotropic liquid crystal, and the element for being operated in VA patterns is different using negative dielectric items
Property liquid crystal, IPS patterns both can be used positive dielectric anisotropic liquid crystal, it is possible to use negative dielectric anisotropic liquid crystal.Wherein, IPS display patterns have
Good viewing angle characteristic and the response time for improving, more and more it is used for multimedia application (such as mobile phone, panel computer), or even for TV
And desktop monitor.
With the development of technology, requirement of the people to display device is being improved constantly, and such as tends to perfect real effect, low-power consumption, fast-response, longevity
Life length etc., this also requires the continuous improving performance parameter of liquid crystal material from side.
The liquid-crystal composition of the big dielectric anisotropy of absolute value, it is possible to decrease the threshold voltage of liquid crystal, further reduces consumption of electric power.
The small liquid-crystal composition of viscosity, can improve liquid crystal display device response speed.When the fast response time of liquid crystal display device, it is applicable to move
Draw display.In addition, in the liquid crystal cell of liquid crystal display device inject liquid-crystal composition when, injection length can be shortened, it is possible to increase workability.Work as liquid
Crystal composite from saturation voltage state be down to threshold voltage state when required time also further reactive mesogen display device response speed.
Liquid-crystal composition is associated to the stability and heat endurance of ultraviolet (UV) with the life-span of liquid crystal display device.Improve liquid-crystal composition pair
The stability and heat endurance of ultraviolet (UV) can extend the life-span of liquid crystal display device.
Prior art cannot take into account the balancing performance problem of big dielectric and fast-response, anti-UV and high-temperature stable, it is impossible to while meeting each side index.
Therefore, in order to obtain the liquid crystal display state of stabilization, above-mentioned requirements are reached, big dielectric low-power consumption, fast is provided by further optimization liquid crystal material
Response, the liquid crystal material of long lifespan, are the striving directions of those skilled in the art.
From the preparation angle of liquid crystal material, the properties of liquid crystal material check and balance influence, and the lifting of a certain performance indications may make
Other performances change.Therefore, prepare all suitable liquid crystal material of various aspects of performance and generally require creative work.
It is an object of the invention to provide a kind of big dielectric, low-power consumption, fast-response, high stability liquid-crystal composition.
