Abstract

The invention provides a positive and negative mixed liquid crystal combination. The liquid crystal combination has large vertical dielectrics, so that the transmittance characteristic of a liquid crystal display can be effectively improved; a first-class compound is added in the liquid crystal combination to increasing parallel dielectrics of the liquid crystal combination, a second-class compound with negative dielectric anisotropy is added to increasing the vertical dielectrics of the combination, a third-class compound is further utilized to reduce the rotational viscosity of the liquid crystal combination, and therefore the liquid crystal combination with quick response and high transmittance is achieved. The liquid crystal combination is suitable for TN, IPS, FFS type liquid crystal displays, and especially suitable for the IPS and FFS type liquid crystal displays.

Description

technical field

[0001] The invention relates to a liquid crystal composition, which belongs to the field of liquid crystal display materials, in particular to a positive and negative mixed liquid crystal composition with high transmittance and its application. Background technique

[0002] At present, liquid crystals are widely used in the field of information display, and at the same time, some progress has been made in the application in optical communication (S.T.Wu, D.K.Yang. Reflective Liquid Crystal Displays. Wiley, 2001). In recent years, the application fields of liquid crystal compounds have been significantly expanded to various display devices, electro-optic devices, electronic components, sensors, etc. For this reason, many different structures have been proposed, especially in the field of nematic liquid crystals, and nematic liquid crystal compounds have been most widely used in flat panel displays so far. Especially for TFT active matrix systems.
