摘要运用Raman光谱与²⁹Si 核磁共振光谱测试 (NMR),研究了液晶显示屏中使用的三种不同类型玻璃的网络结构,包括显示屏盖板玻璃、导电膜玻璃和液晶显示基板玻璃,主要比较光谱中涉及到的桥氧与非桥氧参与的振动比例,来获取玻璃网络结构的紧密度信息。结果表明,导电膜玻璃网络紧密度最低,而液晶显示基板玻璃紧密度最高,显示屏盖板玻璃介于两者之间,而结构紧密度的关系体现在了玻璃性能指标的差异,液晶显示基板玻璃具有最高的应变点、退火点与软化点,而相应的浮法成型工艺温度点也最高,导电膜玻璃则最低。

Abstract: Raman spectroscopy and²⁹Si NMR spectroscopy were used to study the network structure of three different types of glass used in LCD, including cover glass, ITO glass and substrate glass. The vibration ratio of bridging oxygen and non bridging oxygen in the spectra was mainly compared to obtain the tightness information of the glass network. The results showed that the tightness of ITO glass network was the lowest, while the structure of the substrate glass was the densest and the cover glass was between them. The relationship of structural tightness was reflected in the difference of glass performances. The substrate glass showed the highest strain point, annealing point and softening point, and the corresponding float forming point was also the highest, while the index of ITO glass was the lowest.

Key words: liquid crystal display Raman,²⁹Si NMR cover glass ITO glass substrate glass
