Problems solved by technology

For high-resolution products, as the PPI increases and the pixel size decreases, the aperture ratio of the panel decreases sharply. At this time, in order to ensure the brightness of the panel, it is necessary to increase the brightness of the backlight or the number of backlights, but this will greatly increase the power consumption of the panel.

Abstract

The invention discloses a liquid crystal composition and the application of the liquid crystal composition to a liquid crystal display. The liquid crystal composition has positive dielectric anisotropy and is excellent in performance; the refractive index of the liquid crystal composition is larger than 0.100 and smaller than 0.120; the liquid crystal composition is suitable for a liquid crystal panel which is small in thickness and high in respond speed, has a wide application prospect and a good application value, and is particularly suitable for displays which comprise TN-TFT, IPS-TFT and FFS-TFT active matrixes and are high in respond speed, small in thickness, and high in image display quality. The liquid crystal composition comprises the following liquid crystal compounds of I, II, III, IV and V which are shown in the description.

Description

technical field [0001] The invention relates to the field of liquid crystal displays, in particular to a liquid crystal composition and a liquid crystal display containing the liquid crystal composition. technical background [0002] At present, the application range of liquid crystal compounds is expanding more and more widely, and it can be applied to various types of displays, electro-optic devices, sensors, and the like. There are various types of liquid crystal compounds used in the above-mentioned display fields, among which nematic liquid crystals are most widely used. Nematic liquid crystals have been used in passive TN, STN matrix displays and systems with TFT active matrix. [0003] For the application field of thin film transistor technology (TFT-LCD), although the market has been huge in recent years and the technology has gradually matured, people's requirements for display technology are also constantly improving, especially in terms of fast response and high ...
