Abstract

The method aims at establishing a method for measuring reactive monomer content in multiple different liquid crystals at one time. The measuring method comprises respectively utilizing nonreactive monomers contained by the various liquid crystals as internal standard references, diluting by a solvent, then sending into gas chromatography-mass spectrometry (CGMS), detecting the reactive monomers in the various liquid crystals and the specific ion fragments of the internal standard references, and then respectively performing internal-standard-method quantification according to an ion chromatogram, so as to obtain the content of the reactive monomers in the multiple liquid crystals. Therefore, the purpose of measuring the reactive monomer(RM) content in multiple different liquid crystals at one time is realized.

Description

technical field [0001] The invention relates to the field of liquid crystal display panels, in particular to the analysis and detection of photoreactive monomer (RM) content in liquid crystal materials. Background technique [0002] With the high development of the information society, displays for human-machine communication are becoming more and more important. As the leader of flat-panel displays, TFT-LCD (Thinfilm Transistor-liquid crystal display, that is, thin film transistor-liquid crystal display) is currently the only display that has fully caught up with and surpassed CRT in terms of brightness, contrast, power consumption, life, volume and weight. device. It has excellent performance, good mass production characteristics, high degree of automation, and broad development space, and has gradually occupied a dominant position in the display field. The TFT-LCD liquid crystal screen includes a Cell liquid crystal panel, which is composed of liquid crystals sealed bet...
