We fixed reactive monomer (RM) on the side chain of Polyimide (PI), successfully removed the UV2 process, and named as Surface Control Vertivally Aligned (SC‐VA) technology. At present, Polymer Stabilized Vertivally Aligned (PSVA) technology need long time irradiation (UV2 process) to remove residual RM, to ensure good reliabitity performance. The liquid crystal alignment process of SC‐VA same as PSVA, the panel is applied voltage, meanwhile, irradiated by UV light. Reliabitity performance is excellent although bypass UV2 process. The contrast ratio potential improved beacause of smooth PI suface.
