We disassembled two electronic price tags sourced from a supermarket, intending to convert them into calendars. Does anyone have similar experience?
We recently got our hands on a supermarket electronic shelf label (ESL) unit and decided to do a full teardown to understand how these systems actually work in real retail environments.
Most people only see the screen on the shelf, but the internal structure is actually quite interesting.
What is Electronic Shelf Label? Teardown Explained
You need to start by removing the label cover.
Disassemble the exterior to inspect the internal components.
This is the 2.13-inch black-and-white 24-pin display.
Simple but optimized industrial PCB design
The most critical part is not the screen — it’s the backend management system that controls thousands of labels in real time.
The hardware is just the “output terminal”.
Has anyone here worked on large-scale ESL deployments in retail environments? I'd like to display it as an electronic calendar.
