Electronic shelf label (ESL)

The retail market is undergoing significant changes as digitization and retail automation in increasingly embraced. One example of this is the use of e-paper displays as Electronic Shelf Labels (ESLs). Used to display product parameters on shelves, ESLs enable retailers to update prices automatically in real-time across a store (or even multiple stores), eliminating days of tedious and error-prone manual work. To remove the operational costs of manually monitoring and replacing batteries of thousands of units within a retail space, autonomous ESL designs are employing rechargeable batteries with indoor light energy harvesting using miniature solar cells.
