Development of low anchoring strength liquid crystal mixtures for bistable nematic displays

Abstract The recent Bistable Nematic (BiNem®) LCD technology presents long term bistability, high level passive matrix multiplexing, gray levels capabilities and high optical quality. The BiNem® device, based on anchoring breaking, needs specific low anchoring strength materials – alignment layers and liquid crystal mixtures. We present here our approach to develop nematic mixtures with wide enough temperature range and low zenithal anchoring energy.
