A major Chinese supermarket chain has completed a large‑scale digital transformation by deploying Datallen electronic shelf labels (ESLs) across virtually all its in‑store zones.
Covering snacks, beverages, produce, deli, dry goods, bakery, frozen foods, fresh meat & seafood, condiments, home goods, personal care, paper products, eggs, and more – dozens of core categories – the project uses about 10,000 ESLs to achieve true full‑store digitization.

Hardware that adapts to any environment
The deployment includes both ambient four‑color ESLs (for dry aisles and general merchandise) and anti‑freeze waterproof ESLs. The latter operate reliably at -20°C in freezer and fresh food sections.
Main sizes are 4.2″, 2.9″, and 2.66″ – a balance between readability and shelf fit. A full range of mounting accessories (T‑hook, table stand, buckle plug‑in, waterproof box, and iron wire hook) ensures flexible installation on shelves, peg hooks, grid back panels, promotional tables, and cold chain cabinets.


Beyond simple price tags
Datallen’s ESL system solves real retail pain points:
- Ultra‑low power consumption – battery life lasts years, drastically reducing maintenance.
- One‑click bulk updates via cloud platform, eliminating manual errors.
- Custom templates for QR codes, images, and color blocks – brand‑friendly displays.
- Seamless integration with existing POS/ERP systems, backed by Datallen’s technical support.
- Smart assist – flashing LED for item location, automatic price sync.

A replicable benchmark
This case demonstrates how one ESL solution can simultaneously cover ambient, chilled, and frozen environments at scale – a blueprint for other large retailers.
