利用摩擦和光控取向技术在基板上分别做成聚酰亚胺(PI)取向膜。由Cano盒测试方位锚定能的原理,测试了在不同温度下摩擦处理的膜和光控取向膜方位锚定能的变化,发现光控取向膜的方位锚定能随温度变化较为敏感,但主要问题还是锚定强度弱,讨论了改善光控取向膜锚定强度的方法。 A polyimide (PI) oriented film is respectively fabricated on the substrate by using the rubbing and photoalignment technology. The change of the azimuthal anchoring energy of the rubbed film and the photo-alignment film at different temperatures was tested by the principle of the Cano box test azimuthal anchorage. It was found that the azimuthal anchoring of the photoalignment film is sensitive to the temperature change. However, The main problem is that the anchoring strength is weak and the method to improve the anchoring strength of the light-controlling oriented film is discussed.
