Liquid crystal display manufacturing process innovation 2: Photoalignment technology
Photo-alignment equipment is primarily used in the production of liquid crystal displays. This equipment uses linearly polarized ultraviolet light to apply anisotropy to the alignment layer and arrange the liquid crystal in the required orientation. The equipment uses short arc lamps (super-high pressure mercury lamps) and long arc lamps (high pressure mercury lamps or metal halide lamps) as light sources. Use of linearly polarized light to align liquid crystal allows alignment to be conducted in a cleaner environment than was possible with former methods of alignment such as rubbing.
