Abstract
Description
Technical Field
[0001] This invention relates to the field of electronic price tag technology, and more particularly to a power supply device for price tag rails. Background Technology
[0002] Electronic price tags are electronic display devices used in retail settings such as supermarkets, convenience stores, and pharmacies to display product prices, replacing traditional paper tags. In the retail industry, replacing traditional paper price tags in a supermarket requires staff to print, cut, and insert each tag individually—a time-consuming and labor-intensive process. Manually replacing traditional paper tags is prone to errors, potentially leading to discrepancies between the "tag price" and the "checkout price." Furthermore, traditional paper price tags cannot be updated in real time, easily causing price confusion—"one price online, another in store"—and resulting in customer complaints.
[0003] In related technologies, electronic shelf labels are battery-powered and require periodic battery replacement. This is especially true for color LCD screen electronic shelf labels, which consume a lot of power; frequent battery replacements lead to high maintenance costs. Summary of the Invention
