摘要
早期的标准扭曲向列相分段显示LCD电子货架价签卡只能更新价格。控制信息显示量,可以在持续使用中极大地降低电池驱动显示屏的能耗,这满足了一部分零售商对低能耗的需求。而双稳态被动矩阵显示屏不仅可以为零售商提供更多的信息,电池还可以使用数年。文章讨论了双稳态LCD和RF整合的技术,旨在为零售商提供更强的功能性和便利性。
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.
