20120000974 | Self-powered Electronic Label - An electronic label system is provided which includes a data source having information to be displayed by an electronic label. An optical source such as an LED array broadcasts optical signals modulated with the data source data to plural electronic labels. Each electronic label has an optical receiver which receives the modulated optical signals and also receives unmodulated optical signals to supply power to an energy storage device. A mode switch switches the optical receiver between a signal reception mode and an energy storage device power-supplying mode. One or more bistable displays display the data received from the modulated optical signals. Through the use of bistable displays, the power consumption of the electronic label is greatly reduced while use of a single receiving element for receiving both the signal light and power storage light reduces the number of components needed to assemble the electronic label, thus reducing cost. | 01-05-2012 |
