Here is presented a nematic LCD based on an electrophoretically controlled orientational effect in suspension of solid nanoparticles in nematic liquid crystal: electrophoretically controlled nematic (EPCN). Polarity controlled electromigration of the nanoparticles, results in the stabilization of the molecular alignment and provides the bistable/multistable switching in a conventional nematic LC cell. The EPCN display allows multiplexing with intrinsic grey scale capability, high resolution and contrast, uses standard LCD materials and techniques and is easily producible by plastic technology.
