Photo-alignment technology for vertically aligned LCDs

Rolic® light-controlled molecular orientation (LCMO) is a state-of-the-art photoalignment technology used in todays mass production for vertically aligned (VA) liquid crystal display (LCD), where high-resolution LC director patterning with well-defined azimuthal and pretilt angles is required. We provide a description of the LCMO mechanism and show the positive impact of the lower pretilt angle on the intrinsic transmittance of VA-LCDs. Novel LCMO-VA materials for ultra-high definition LCDs are also presented.
