Abstract

We describe a new kind of bistable nematic display where bistability is achieved by a field induced surface anchoring transition. The system uses simple planar anchorings with different strengths. The system is intrinsically fast, with a writing response time in the 30 microseconds range on the order of 20 V pulses, and a contrast on the order of 10. We describe the physics of coupled field induced anchoring transitions which explains these properties.
