Shelf edge · price · promotion

Displays that sell at the shelf.

The shelf edge is where buying decisions happen. We put full-colour Android displays on powered rails, e-paper signs where power is scarce, and QR-scanning bars that switch to the product a shopper scans — all updated remotely.

PT Series price-tag displays mounted on a powered shelf rail

How it works

From your price system to the shelf edge.

Prices and promotions come from your system — a content platform, your ERP or LUMA AI Studio — and reach every display over the network. The displays snap onto a powered rail, so a shelf needs one power feed instead of a cable per screen.

Use cases

Where this hardware works.

Common applications by industry, and the setup we would typically build for each. Every project starts from your site, so sizes and parts change with it.

Supermarkets

Shelf prices that match the till

Prices on the shelf edge change from the store system overnight, so the shelf and the checkout always agree.

Typical setup: PT Series displays on powered rails in key aisles; e-paper signs where there is no power.
What matters here: Price accuracy without printing and swapping paper labels.

Fresh food and bakery

Markdowns before the sell-by date

Short-dated products are marked down in steps through the day so they sell before they expire.

Typical setup: Shelf displays in fresh and bakery aisles, with prices from the store system.
What matters here: Fast, repeated price changes with no relabelling by staff.

Electronics stores

Compare models at the shelf

Shoppers scan a product and the screen shows specifications, comparisons and reviews, or a link to order online.

Typical setup: A 29" QR-scanning bar (1920×540) and stretched bars above display tables.
What matters here: Product detail at the shelf without waiting for staff.

Shelf-edge media

Shelf strips that sell space to brands

Full-colour strips along the shelf edge play brand video and promotions next to the product, sold as retail media.

Typical setup: Stretched bar displays and PT Series displays on powered rails, fed by the retail media platform.
What matters here: Bright full-colour video where an e-paper label can only show a price.

Pharmacies and drugstores

Product information on demand

A QR code at the shelf opens usage, ingredients and origin, while screens explain promotions and services.

Typical setup: Shelf displays and e-paper signs with QR codes, plus counter displays.
What matters here: Clear information in a small space.

Pop-up stores and events

Signs that need no outlet

Price and promotion signs on tables, counters and stands at tastings, launches and events.

Typical setup: Double-sided 10" battery table signs that play for 5–6 hours, up to 8.
What matters here: Set up anywhere in minutes.

Why iTEMP

One team, from the board to the software.

A typical rollout stitches together a board vendor, a panel supplier, a firmware contractor and a software team. We design the board, build the display and write the firmware ourselves, then integrate your software — so when something has to change, one team changes it.

01 BoardDesigned in-house
Our KTM boards inside every shelf display, on the same firmware as all our devices.
02 Display and enclosureBuilt in our factory
Shelf displays, stretched bars and e-paper signs built in our factory, with the rail and connectors designed together.

03 FirmwareWritten by our team

Rotation, brightness and power schedules set through the system API; displays restart themselves every night.

04 Software and testingIntegrated and burned in
Prices from your software or LUMA AI Studio. Every unit runs a one-to-two-day burn-in before it ships.

Custom development

Built to your spec.

Standard products ship as they are. For a project, any of these can change — and because the board, display and firmware are ours, the change is made at the source.

How a custom project runs

Display size, orientation, single or double-sided
Rail length and mounting for your shelving
Your price or content app preinstalled
Scanner integration on bar displays

Products

Hardware for this job.

Displays run Android, so prices can come from your content system or your own software.

FAQ

Smart Retail

ESL or a price-tag display?

Electronic shelf labels for low-cost price labels; full-colour PT displays where the shelf should promote. Many stores combine both.

How are prices updated?

Remotely, from your content system or your own software — the displays run Android, so either works.

How many displays can one rail power?

A 50 cm rail (12 V / 3 A) powers up to two displays; 1 m and 2 m rails (12 V / 5 A) up to four. A desk stand powers one.

What does the QR-scanning bar do?

It reads a product barcode or QR code and switches the screen to that product — price, details, a coupon or a review page.
