Description

A kind of negative dielectric liquid crystal composition containing benzofuran compound and its application
Technical field
The present invention relates to a kind of liquid-crystal composition, specifically a kind of nematic phase liquid crystal composition, exactly, this hair Liquid-crystal composition provided by bright has negative dielectric anisotropy, more specifically liquid-crystal composition tool provided by the present invention There is the fast response time.
Background technique
With the raising that people require display effect, the requirements such as curved-surface display, high transmittance, high contrast increasingly by To the favor of more consumers, the demand that curved-surface display and high transmittance, high contrast may be implemented with PSVA technology is relied on, is fitted For large size panel demand, transmitance of the negative liquid crystal for liquid crystal display to can be improved in FFS mode is shielded with hard, reduces back Light power consumption increases cruise duration, is suitable for the mobile display devices such as mobile phone, plate.
Negative liquid crystal is most proposed earlier than the end of the eighties in last century, is mainly used for VA mode, major advantage is to compare Degree is high, and major defect is that visual angle is small, and the response time is slow.With the development of display technology, the technologies such as MVA, PVA, PSVA go out in succession It is existing, solve the problems, such as response time and visual angle.In recent years, as touch screen becomes the mobile device market mainstream, IPS and FFS The hard panel type display of class has inborn advantage, IPS and FFS class display both can be used positivity liquid crystal, negativity also can be used Liquid crystal is bent electric field as present in the class display, and positivity liquid crystal is arranged along electric field line direction, curved so as to cause molecule Song, and decline in transmitance；Negative liquid crystal is arranged perpendicular to electric field line direction, thus transmitance can be substantially improved, and be current It promotes transmitance, reduce backlight power consumption the best way.But response time problem existing for negative liquid crystal is the weight currently encountered Hang-up, the FFS display response time slow 50% or more using the FFS display of negative liquid crystal relative to positivity liquid crystal. Therefore, the response time for how promoting negative liquid crystal becomes current key problem.
Specifically, the response time of liquid crystal display, (d was thickness of liquid crystal layer, and γ 1 is liquid depending on (d^2 γ 1)/Keff Brilliant rotary viscosity, Keff are effective elastic constant), therefore, rotary viscosity is reduced, thickness of liquid crystal layer is reduced and promotes elastic constant It can achieve the purpose for improving the response time, thickness of liquid crystal layer depends on the design of liquid crystal display；For liquid-crystal composition, It reduces rotary viscosity and thickness of liquid crystal is most effective.
