2.13 Inch 122x250 E Ink Display Module SSD1680 Driver 4-SPI 24 Pin Shelf Tag Panel

The 2.13 inch format is the workhorse of electronic shelf labelling, and this module pairs a 122x250 electrophoretic matrix with the SSD1680 controller. The film works by moving charged pigment inside microcapsules with a short electrical pulse: white particles to the front for a bright field, black for a dark one, with red or yellow available in the colour builds. Once the pulse ends the pigment settles and the image stays without power, which is why a shelf tag can show a price for months on a coin cell. The 23.71 x 48.55 mm active area is deliberately tall, matching a rail: a name, a unit price and a barcode stack vertically without shrinking type. The 24 pin 0.5 mm FPC and a wide 2.2 to 3.7 V supply make the module tolerant of a cell that has drifted toward end of life.

Supermarket shelf rails show a price and a promotion flag. Pharmacy strips show a reimbursed price and a dosage note. Convenience store peg hooks show a planogram code. Liquor store shelf talkers show an origin and a volume. Garden centre plant markers show a variety name and a care icon. Each is replaced on a promotion cycle, and each must be read at a glance by a shopper walking past.

Three features decide the choice. The 122x250 vertical ratio matches rail hardware already installed, so an estate upgrades without new clips. The SSD1680 keeps firmware common with the smaller 2.13 inch tags a chain may already run, which shortens the integration test. And the wide 2.2 to 3.7 V window means a tag keeps working as the cell fades, instead of dropping off the network at a fixed threshold. At 3.24 g with a 1.0 mm profile, the module does not bow a plastic rail.

The panel shows price, unit price, barcode and a red or yellow promotion band, updates over SPI with a full refresh for a new layout and a partial refresh for a number change, and keeps the last price visible through a battery change. Because the image is bistable, a tag that loses radio contact still displays the correct last known price.

Deploy by mapping the tag to its rail position, connecting the FPC, sending the SSD1680 initialization table, writing a frame and refreshing fully. Later price edits arrive as partial refresh commands from the access point, and a full refresh should be scheduled after each battery replacement so residual pigment is cleared.

The 0 to +40 C operating window is narrower than the storage range, so a tag destined for a chiller cabinet or a sunlit window needs a housing check before approval. Avoid condensation, do not flex the FPC when clipping into the rail, and keep cleaning fluid away from the film edge, since the seal is the first part to fail.

Shipments leave 5-10 working days after payment, consolidated per store or distribution centre. Pilot aisles go by express, chain rollouts by air or sea, and capacity of 100,000 pieces monthly supports phased store openings.

T/T, L/C at sight and Western Union are accepted. Trials are paid upfront, rollouts follow a deposit plus balance against documents, and repeat orders release against purchase orders.

Tags ship with protective film in anti-static trays, wrapped in bubble film and sealed with a moisture barrier inside an export carton labelled by store or SKU range for easy splitting.

Minimum order is 10 pieces, enough to test a rail. Transit damage or first power-up failure is replaced after photo verification, the 12 month warranty applies, and our team supports template design and access point mapping.
