ESL and E-paper POP Displays: Different Roles on the Same Retail Shelf

Electronic Shelf Labels and E-paper POP displays can both use E Ink technology, but they serve different purposes. ESL manages shelf information. E-paper POP communicates the brand and campaign. They are not replacements for each other; they can work side by side.

Same E Ink foundation. Different display architectures. Complementary roles in retail.

At a glance

Two roles on the same retail shelf

01

Electronic Shelf Label (ESL)

The shelf information layer. An ESL is a compact digital price tag that presents price, SKU, barcode, promotion or stock information and is commonly connected to a retailer's central management system.

02

E-paper POP Display

The brand communication layer. An E-paper POP display combines changing electronic paper segments with printed campaign artwork and a custom structure to attract attention and explain a selected product.

Inside the display

The same E Ink technology, built differently

Both products share the reflective, paper-like appearance, wide viewing angles and bistable low-power behavior associated with E Ink. The key difference is how the image is constructed: graphic ESLs normally use a pixel matrix, while SoliDisplay E-paper POP uses flexible, predefined segments.

ESL display architecture

Active-matrix dot-matrix E-paper

Individually controlled pixels can render changing prices, text, barcodes and graphics in monochrome or selected color E Ink platforms.

SoliDisplay POP architecture

Flexible segmented E-paper

Predefined black-and-white segments create planned visual changes and can be shaped around printed campaign artwork and the POP structure.

Display platformESL uses an active-matrix dot-matrix panel; SoliDisplay E-paper POP uses flexible segmented E-paper.
Color systemESL can use black and white, Spectra 3000 three-color, Spectra 3100 four-color, and selected newer Spectra 6 formats. E-paper POP uses changing black-and-white segments with a full-color printed overlay.
Image logicA matrix renders different digital layouts pixel by pixel. A segmented display switches predefined campaign shapes in a planned sequence.
Physical formatESL modules are commonly rigid and rectangular. Flexible segmented E-paper can follow custom two-dimensional shapes and integrate with a POP structure.

Working together

Designed to work together

The ESL below a product can keep its price and product data accurate, while an E-paper POP display beside it adds campaign movement, product benefits and a stronger branded message. One supports retail operations; the other supports in-store communication.

01
Shelf edge layer

ESL displays the current price, product code and operational information below the product.

02
Campaign layer

E-paper POP sits beside or around selected products to present benefits and branded visual movement.

03
Shared benefit

Both retain a paper-like, reflective appearance and consume very little power between visual changes.

04
Combined result

Accurate shelf information and stronger campaign communication can coexist in one retail experience.

One shelf, two communication layers

01 / ESLAccurate shelf data

Price and product information stay clear at the shelf edge.

02 / E-paper POPVisible campaign story

Motion and printed artwork bring attention to selected products.

Together: information accuracy plus campaign impact

Common questions

FAQ

Is an E-paper POP display the same as an electronic shelf label?

No. Both can use E Ink technology, but graphic ESLs normally use a dot-matrix display for changing data, while SoliDisplay E-paper POP uses flexible predefined segments for campaign visuals.

Which E Ink color technologies can be used for ESL?

ESL products can use black-and-white E-paper as well as color platforms such as Spectra 3000 and Spectra 3100. Selected newer ESL and retail signage formats can also use Spectra 6.

Can ESL and E-paper POP displays be used in the same store?

Yes. ESL can manage accurate shelf information across many products, while E-paper POP can add a larger branded message around selected launches, promotions or priority products.

Can segmented E-paper display any new image?

Segmented E-paper switches predefined shapes rather than rendering an unrestricted pixel image. The segment pattern, visual sequence and printed overlay are therefore designed around the campaign before production.
