Abstract:
A method of producing spatially varying pretilt angles across a liquid crystal cell coats a substrate with a polyimide alignment layer and a layer of photoalignment material on top of the polyimide layer. An applied beam with variable light dosage spatial or temporal profiles is then used to achieve a corresponding pretilt angle distribution.
