10.2 Inch E Ink Display Module for Supermarket Price Signs

10.2 Inch E Ink Display Module for Supermarket Price Signs

A red-and-white SPI panel sized for reusable supermarket pricing and promotion graphics.

The 10.2 Inch E Ink Display Module is a 960×640 electronic-paper component for supermarket price boards, promotion cards and reusable retail notices. Its red-and-white display format supports high-contrast price figures, product names and promotional highlights, while the 215.52 × 143.68 mm active area provides more content space than a compact shelf-edge label.

The panel uses an SPI interface for integration with an external host or controller. It is a display component rather than a complete wireless electronic shelf label, so the final system must separately address the processor, power design, communications, enclosure and content-update workflow.

Key Specifications at a Glance

Final electrical, timing and mechanical compatibility must be based on the approved module specification and sample.

Product Overview

The 10.2 Inch E Ink Display Module is intended for retail information that changes periodically rather than continuously. A 960×640 canvas can accommodate large prices, product descriptions, origin information, weight, promotional text and simple graphic elements.

Its red-and-white output is particularly relevant where red is used to separate promotional prices, discounts or priority messages from the main white content area. The exact background and pigment behavior should be checked on a physical sample because the provided facts define only the available colors, not contrast, reflectance or refresh characteristics.

Larger retail information area

The 215.52 × 143.68 mm active area supports layouts that would be difficult to fit on a small shelf-edge tag. Potential formats include produce price cards, end-cap promotions, service-counter notices and reusable product-information signs.

Resolution and content planning

A 960×640 pixel image should be prepared around the panel’s native aspect ratio. Font size, stroke thickness, red-area coverage and graphic complexity should be tested on the real display rather than judged only from a desktop preview.

The design workflow should preserve the confirmed red-and-white color limitation. Black or grayscale output must not be assumed without confirmation of the exact panel version.

E Ink Display Behavior for Retail Signs

Electronic-paper technology is commonly selected for information that remains static between updates. For this module, however, update time, waveform requirements, ghosting behavior and retained-image performance are not specified and require engineering confirmation.

Appropriate content types

The panel may be considered for:

• Supermarket produce prices
• Promotional price cards
• Shelf-end product information
• Fresh-food counter notices
• Reusable retail campaign signs
• Inventory or availability notices
• Low-update-rate service information

The module is not documented as a video, animation or frequently refreshing display.

Red-and-white graphic hierarchy

Red can be reserved for sale prices, discount labels or attention elements, while white areas can carry the supporting information. The content-generation system must use the correct pixel encoding and update process for the approved module.

SPI Integration and Host Compatibility

The SPI designation identifies the communication family, but it does not establish the exact connector, pin assignment, operating voltage, clock rate, signal polarity or initialization sequence.

An SPI interface name alone does not guarantee compatibility with an existing controller board.

Information required from the module specification

Before PCB design, confirm:

• Connector and FPC details
• Complete pin assignment
• Logic and panel voltage requirements
• SPI clock and signal timing
• Chip-select behavior
• Reset and busy-signal requirements
• Image-data format
• Update waveform resources
• Power-on and power-off requirements
• FPC contact side and orientation

Panel versus complete electronic shelf label

The 10.2 Inch E Ink Display Module should not be treated as a complete electronic shelf label without additional hardware.

A finished ESL may require a processor, memory, radio, battery or power supply, antenna, housing, mounting system, communication gateway and label-management platform. None of those system elements is confirmed as part of this panel.

A controller or adapter board may therefore be required between the display and the selected host platform.

Mechanical Layout and Enclosure Planning

The confirmed active area is 215.52 × 143.68 mm. This value describes the visible image region, not the total module outline or enclosure opening.

Active area is not the outside dimension

The bezel aperture must not be designed from the active-area value alone. The complete drawing is needed to determine:

• Overall width and height
• Panel thickness
• Border dimensions
• FPC exit position
• Connector clearance
• Mounting tolerances
• Front-window overlap
• Protective-cover requirements

FPC routing

The product image shows a bottom FPC connection. The enclosure should provide a controlled bend radius, strain relief and clearance from sharp metal edges. Final routing depends on the confirmed FPC length, contact side and connector position.

When to Choose This Display Module

This module is a practical candidate when the project requires:

• A 10.2-inch retail information area
• Native 960×640 content
• Red-and-white promotional graphics
• Periodic rather than video-rate updates
• SPI host integration
• A custom enclosure or price-card assembly

A different display should be considered when the project requires full color, video, rapid animation, standard HDMI input, integrated wireless communication, confirmed touch operation or a ready-to-deploy complete ESL device.

Customization and Project Qualification

Customization scope is not confirmed from the available technical information. Requested changes to the FPC, interface, color version, mechanical construction, branding, protective front or controller integration require a separate feasibility review.

Custom configurations are generally evaluated according to tooling requirements, material availability and the requested specification. Sample quantities and production quantities are confirmed separately.
