Abstract

The invention discloses a positive and negative mixed liquid crystal composition. The positive and negative mixed liquid crystal composition is characterized by comprising an additive component A which consists of one or more compounds shown in a general formula S-1, a general formula S-2, a structural formula S-3 and a structural formula S-4, a component B which consists of one or more negative compounds shown in a general formula I and a component C which consists of one or more positive compounds shown in a general formula II. According to the positive and negative mixed liquid crystal composition, the problems of low transmittance, low response speed and especially poor anti-ultraviolet capability of the conventional liquid crystal mixture 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...
