12.3 Inch Stretch Bar Advertising Screen for Retail Signage

12.3 Inch Stretch Bar Advertising Screen for Retail Signage

This panoramic 1920 × 720 IPS kit combines DVI and VGA control hardware with a narrow-format screen for controlled-light retail and embedded signage.

Product Summary

The 12.3 Inch Stretch Bar Advertising Screen combines a panoramic IPS Pro panel with an M.NT68676 controller, converter board, signal cable, and wired OSD keypad. Its 1920 × 720 canvas is suited to shelf messaging, counter displays, product-information bands, compact menu strips, and embedded commercial interfaces that need more horizontal space than a conventional small monitor provides.

The panel uses a 50-pin, dual-channel, 8-bit LVDS connection and 3.3 V typical panel logic. The controller accepts DVI and VGA video inputs and requires a 12 V DC supply rated above 2 A. This configuration is a component-level screen-and-controller kit rather than a finished advertising monitor: no enclosure, front glass, environmental sealing, mounting frame, media player, or touch system is confirmed.

The listed luminance is 700 cd/m² typical. That value must be confirmed against approved product documentation and tested in the intended lighting. It does not support sunlight-readable, high-brightness, outdoor, or window-facing claims.

Key Specifications

Stretch-Bar Content and Optical Planning

Native 1920 × 720 Artwork

The 292.032 × 109.512 mm active area creates a long horizontal display zone. Artwork should be prepared at the native 1920 × 720 resolution rather than resized from 1920 × 1080 content. Native layouts preserve text proportions and help prevent cropping, stretched product images, or unused regions.

This format can divide the screen into product name, price, promotion, status, and navigation zones. Text size and contrast should be validated at the actual viewing distance because the narrow height limits how many information rows can remain legible.

IPS Pro Viewing Behavior

IPS Pro, normally black operation, and the listed 85° viewing values support viewing from several positions around a shelf, counter, or equipment console. Final readability still depends on mounting angle, interface colors, front-window reflections, and the position of overhead lighting.

The 700 cd/m² Boundary

The listed 700 cd/m² luminance is appropriate only for controlled-light evaluation until the value is confirmed and the assembled product is tested. A front lens, tinted cover, bonding layer, or reflective site can reduce perceived brightness further.

The listed 700 cd/m² value does not establish high-brightness or daylight-readable performance.

Projects requiring brightly lit retail aisles, storefront windows, direct daylight, or outdoor operation should qualify a different luminance configuration rather than extrapolating from this kit.

Integrating the 12.3 Inch Stretch Bar Advertising Screen

50-Pin LVDS and Firmware Matching

The panel uses dual-channel, 8-bit LVDS through a 50-pin connector. A matching connector count does not prove that another panel or controller is compatible.

A matching 50-pin connector does not establish compatibility without verified timing, voltage, channel mapping, pin assignment, cable orientation, and firmware.

Before first power-up, confirm:

• Native 1920 × 720 timing
• Dual-channel, 8-bit LVDS mapping
• Complete 50-pin assignment
• Connector contact direction
• Cable orientation
• 3.3 V panel logic
• M.NT68676 firmware
• Converter and WLED wiring

DVI and VGA Source Inputs

The confirmed controller inputs are DVI and VGA. DVI supports a digital host path, while VGA can serve legacy computers, industrial systems, and established media sources. HDMI, USB playback, network content management, Android operation, and audio functions are not confirmed for this selected configuration.

The wired keypad provides OSD access for brightness, contrast, automatic adjustment, and language settings. Its position should remain accessible during qualification and servicing.

Separate Power Domains

The M.NT68676 controller requires 12 V DC above 2 A, while the panel logic is listed at 3.3 V typical.

The 3.3 V panel logic rail and the 12 V controller input are separate power domains.

Do not route the 12 V controller input directly to the panel logic rail. The approved wiring diagram should identify controller input, regulated panel power, LVDS cable, converter connections, WLED backlight path, enable control, dimming path, and ground references.

Mechanical and Enclosure Integration

Panel and Viewing Opening

The active area is 292.032 × 109.512 mm and the panel outline is 308.1 × 120.6 × 7 mm. The front opening should expose the intended active image while providing safe border overlap and assembly tolerance.

The design should allow for cable exits, connector clearance, panel support, front-window overlap, strain relief, and service access. The LCD glass and connectors must not carry structural enclosure loads.

Controller-Board Clearance

The controller board measures 125 × 58 × 17 mm. Extra space is required for the DVI connector, VGA connector, 12 V input, LVDS cable, converter wiring, and keypad lead. Use insulated mounting points and prevent the board from contacting conductive housing surfaces.

Included and Excluded Items

The package includes:

• M.NT68676 LCD controller
• 12.3-inch LCD panel
• Converter board
• Signal cable
• Wired OSD keypad

A power adapter, enclosure, mounting hardware, protective glass, touch sensor, touch controller, media player, speakers, network module, and environmental protection are not confirmed.

Advertising and Embedded Application Fit

The 12.3 Inch Stretch Bar Advertising Screen can support controlled-light retail shelf headers, product-information bands, indoor counter promotions, compact menu strips, equipment status displays, and protected embedded HMI prototypes.

The panoramic format is useful where a conventional monitor is too tall or where content must align with a shelf, fascia, console, or narrow opening. DVI and VGA control can also simplify evaluation with existing computers and industrial video sources.

This kit should not be positioned as a complete digital-signage player. Content playback, scheduling, networking, remote management, enclosure safety, thermal management, and site mounting depend on the surrounding system. Outdoor, vehicle-grade, medical, continuous-duty, and weatherproof suitability are not established.

Capacitive touch is not confirmed for this configuration.

A touch project must define the sensor technology, controller, communication interface, cable, cover-lens dimensions, bonding method, firmware, and host support separately.

Customization and Procurement

Project review may cover controller firmware, LVDS cable mapping, board revision, brightness verification, cover glass, anti-glare or anti-reflective treatment, optical bonding, optional touch development, enclosure design, mounting, cable length, branding, and packaging.

Customized packaging is shown from 1,000 sets. Other customization quantities and technical scope should be confirmed after the required functions, materials, tooling, and drawings are defined.
