▎ 摘　　要

NOVELTY - The label has a display module (10) with a display surface (100); a rectenna module (11) disposed on the display surface of the display module; and a control drive module (12) used to convert an electrical energy signal into electrical energy to power the label and used to send a command signal to display module. The display module is further used to display a label signal on display surface according to command signal. It is e.g. electronic paper (e-paper). The rectenna is made of metal grid, indium tin oxide (ITO), graphene film or sputtered thin metal film. USE - Wireless electronic label e.g. electronic shelf label (ESL) for use in a wireless electronic label system of shops, stores, or department stores for displaying product pricing and related information. ADVANTAGE - The space above the display surface of the display module can be used effectively, so that the effect of reducing the volume or area of the wireless electronic label can be achieved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a wireless electronic label system. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a wireless electronic label.
