Previous electronic shelf‐edge labels based on standard twisted‐nematic segmented LCDs have allowed updates of price only. Limiting the information shown meant ultra‐low‐power requirements for the battery‐operated displays in constant use, which in turn supported the need for low cost on the part of retailers. Bistable passive‐matrix displays allow retailers to supply more information while also enabling battery options that last for years. This article discusses a bistable LCD and RF protocol designed to provide both functionality and ease of use for retailers.
