Abstract

The invention discloses a positive-negative-mixed liquid crystal composition. The positive-negative-mixed liquid crystal composition comprises an additive component A, a component B and a component C, wherein the additive component A comprises one or more compounds shown in formula S-1, formula S-2, formula S-3 and structural formula S-4, the component B comprises one or more negative compounds shown in formula I, and the component C comprises one or more positive compounds shown in formula II. By the positive-negative-mixed liquid crystal composition, the problems that existing liquid crystal compositions are low in transmittance, slow in response and poor in UV resistance are solved.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal materials, and in particular relates to a positive and negative mixed liquid crystal composition and its application in liquid crystal displays. Background technique [0002] Display is the process of converting data information with electrical signals as the medium of transmission into visual information with visible light as the medium of transmission. The device that completes the display is the Man-Machine Interface (MMI). A flat panel display (Flatpanel Display, FPD) is currently the most popular type of display device. Liquid Crystal Display (LCD) is the first product developed and commercialized in FPD. At present, a thin film transistor liquid crystal display (ThinFilmTransistorLiquidCrystalDisplay, TFT-LCD) has become a mainstream product in LCD applications. [0003] In terms of working principle, LCD is a display device that uses the light emitted by the backlight to generate l...
