ELECTRONIC LABEL SYSTEM
First Claim
1. An electronic label system, comprising:
- a control unit, sending display information;
a first net unit, coupled to the control unit, and configured to convert the display information into a display signal;
a second net unit, coupled to the first net unit, and configured to receive the display signal and output a display control signal; and
a plurality of electronic label units, coupled in series to the second net unit, and configured to receive the display control signal and to respectively display according to the corresponding display control signal, wherein the electronic label units respectively output a plurality of state information to the control unit, so that the control unit monitors operation states of the electronic label units according to the state information,wherein the state information is transmitted to the control unit when a state of the electronic label units is varied.

Abstract
An electronic label system including a control unit and a plurality of electronic label units is provided. The control unit transmits wireless power. The electronic label units are coupled to the control unit. The electronic label units respectively output a plurality of state information to the control unit, so that the control unit monitors operation states of the electronic label units according to the state information. The state information is transmitted to the control unit when a state of the electronic label units is varied. The control unit transmits the wireless power to the electronic label units by using wireless communications, and the electronic label units are charged with the wireless power. Furthermore, a wired communication interface is used as the communication interface between the net unit and the electronic label units in the electronic label system, so that the cost of the electronic label system is reduced.
