Abstract
Provided are an electronic shelf label, an electronic shelf label system, and an electronic shelf label method. The electronic shelf label includes a power supply unit configured to provide driving power to one or more terminals, a communication interface configured to provide a display signal to the one or more terminals, a terminal selection unit configured to select a terminal to be controlled among the one or more terminals, and a controller configured to control the terminal selection unit so as to select the terminal to be controlled and generate the display signal.
Claims20
An electronic shelf label comprising:
- a power supply unit configured to provide driving power to one or more terminals;
- a communication interface configured to provide a display signal to the one or more terminals;
- a terminal selection unit configured to select a terminal to be controlled among the one or more terminals;
- and
- a controller configured to control the terminal selection unit so as to select the terminal to be controlled and generate the display signal.
A terminal comprising:
- a display unit configured to output an image based on a display signal and a driving voltage provided from a control device;
- and
- a circuit unit including a driving power reception unit that generates a driving voltage based on driving power provided from the control device, and configured to provide the driving voltage to the display unit when a terminal to be controlled by the control device is selected.
An electronic shelf label method comprising:
- setting a setup switch of a plurality of terminals;
- supplying, by a control device, power to the plurality of terminals;
- providing, by the control device, a PWM signal corresponding to a terminal to be controlled to the plurality of terminals;
- driving power of the terminal to be controlled, based on the PWM signal;
- providing, by the control device, a display signal to the plurality of terminals;
- and
- outputting an image in the terminal to be controlled, based on the display signal.
