The invention relates to the technical field of liquid crystal materials, in particular to a negative liquid crystal composition with quick response time and application thereof. The liquid crystal composition comprises at least one compound represented by a general formula I, at least one compound represented by a general formula II and at least one compound represented by a general formula III.The liquid crystal composition has low rotary viscosity, large elastic constant, good low-temperature intersolubility and high response speed, can be used for fast response liquid crystal displays invarious display modes, can obviously improve the display effect of liquid crystal displays when being used in the displays in a VA/MVA/PVA/PSVA, IPS or FFS mode, and can effectively shorten the response time of the liquid crystal displays.
Description
technical field [0001] The invention relates to the technical field of liquid crystal materials, in particular to a negative liquid crystal composition with fast response time and its application. Background technique [0002] With the improvement of people's requirements for display effects, curved display, high transmittance, high contrast and other requirements are more and more favored by more consumers, relying on PSVA technology can achieve curved display and high transmittance, high contrast Demand, suitable for large-size panel demand, negative liquid crystal used in FFS mode can improve the transmittance and hard screen of the liquid crystal display, reduce backlight power consumption, increase battery life, and is suitable for mobile display devices such as mobile phones and tablets. [0003] Negative liquid crystal was first proposed in the late 1980s. It is mainly used in VA mode. Its main advantage is high contrast, and its main disadvantages are small viewing a...
