Polyimide alignment layer is a very important liquid crystal alignment. The most well-known Liquid crystal display (LCD) alignment methods are homogeneous alignment and homeotropic alignment. This paper research uses different fluff depth and number of rubbing into polyimide,and changes the level of rubbing strength, to observe how electro-optical properties of vertical liquid crystal alignment changes with rubbing strength.
By rubbing polyimide with different rubbing strength, this research uses two kind of negative liquid crystal (¡µ£`<0) as samples. This research finds that when rubbing strength increases, the contrast ratio tends to drop.However, the contrast ratio rises after certain level of rubbing strength is applied. Regarding the response time, this research finds that when rubbing strength increases, the response time tends to drop as well. However, the response time rises and falls irregularly after certain level of rubbing strength is applied.
