47.6 Inch Dual Facing LCD Signage Display for Public Corridors

47.6 Inch Dual Facing LCD Signage Display for Public Corridors

This two-faced commercial display combines a native 1920 × 360 canvas, 700 cd/m² luminance and Android-based media playback for covered public spaces.

Product Summary

The Dual Facing LCD Signage Display is designed for corridors, entrances, concourses and other circulation areas where people approach from two directions. Its opposing screen faces allow one suspended or structure-integrated unit to present wayfinding, announcements or promotional content to audiences on both sides.

Each display face uses a wide 1920 × 360 content format. The complete unit measures 1199.84 × 241.42 × 55 mm and provides an active image area of 1189.44 × 223.02 mm. The elongated format is suitable for directional messages, store promotions, service information, transport notices and event guidance.

The system includes Android 7.1 on an RK3288 processing platform and identifies HDMI, USB and TF card as content-input routes. The playback workflow, network functions and ability to run different content on each face must be defined during project review.

Key Specifications

Planning Content for Two Opposing Display Faces

Same-content and different-content workflows

A dual-facing housing does not automatically establish how the two screens are controlled. The project specification must state whether both faces will show the same content or require separate playlists.

Synchronized content is appropriate for:

• Directional arrows
• Public announcements
• Event schedules
• Safety notices
• Building information
• General promotions

Different content may be preferred when each side faces a different destination, tenant group or traffic flow. This requirement must be confirmed against the media-player and control architecture before deployment.

The Dual Facing LCD Signage Display should not be described as independently controlled until the controller configuration, video routing and software functions have been verified.

Native 1920 × 360 artwork

Artwork should be created directly at 1920 × 360 pixels. Scaling conventional 16:9 advertising content into the ultra-wide space can produce undersized text, excessive cropping or large unused areas.

Effective layouts generally use:

• One primary message
• A short supporting line
• Directional icons
• A limited number of product images
• High-contrast typography
• Controlled animation speed
• Clear spacing between information zones

The production team should test actual artwork on a sample at the intended viewing distance. Text height, image cropping and message duration should be evaluated from both traffic directions.

Android and Media Input Integration

Android 7.1 application review

The integrated system is identified with Android 7.1 and an RK3288 quad-core Cortex-A17 processor operating at 1.8 GHz. This provides a defined playback platform, but software suitability depends on the application package, codec, security requirements and peripheral configuration.

Before approval, provide:

• Required application package
• Supported Android version range
• Video and image formats
• Playlist structure
• Startup behaviour
• Orientation requirements
• Offline playback requirements
• Restart and recovery rules
• Required language support
• Content-update procedure

Android compatibility should be validated with the production-intent application rather than assumed from the operating-system name alone.

HDMI, USB and TF-card content routes

HDMI can be used for an external media source when the approved configuration exposes a usable input. USB and TF card support local media workflows, subject to supported file systems, codecs and playback software.

The engineering review should determine:

• Primary content source
• Backup content source
• Required connector access
• Removable-media security
• File-update procedure
• Cable retention
• Service access
• Automatic playback behaviour
• Recovery after power interruption

Wi-Fi, Ethernet, cloud publishing and remote monitoring are separate requirements and should be specified explicitly rather than inferred.

Mechanical Integration of the Dual Facing LCD Signage Display

Housing dimensions and mounting support

The overall housing measures 1199.84 × 241.42 × 55 mm. The mounting system must support the complete finished unit rather than only the LCD glass or one enclosure edge.

A mechanical review should cover:

• Suspension points
• Bracket spacing
• Structural load
• Installation orientation
• Ceiling or wall material
• Safety retention
• Alignment between both faces
• Vibration from nearby equipment
• Service removal
• Local installation requirements

The installation drawing should include all fasteners, secondary safety restraints and cable-entry positions.

Cable, service and ventilation access

The 150 W product reference requires coordinated power delivery and thermal planning. Cable entry should avoid sharp bends, pinch points and visible loops below a suspended installation.

Provide clearance for:

• AC or DC power hardware
• HDMI cables
• USB devices
• TF-card access
• Controller service
• Ventilation paths
• Maintenance tools
• Mounting adjustment
• Safe unit removal

The enclosure should not be boxed into an unventilated cavity without a thermal assessment.

Optical, Power and Temperature Boundaries

The standard luminance is 700 cd/m². This supports evaluation in well-lit indoor and covered public areas, but it does not establish direct-sun performance.

Finished-system readability depends on:

• Ambient illumination
• Screen reflections
• Viewing distance
• Installation height
• Content contrast
• Protective-front construction
• Dust accumulation
• Display orientation
• Temperature inside the housing

The 700 cd/m² value should therefore be tested at the actual site or in a representative lighting environment.

The 150 W figure is a complete-product power reference for electrical and thermal planning. The branch circuit, power conversion, cabling and protective devices should be selected for the approved production configuration.

The stated operating range is 0°C to +50°C. Installations outside that range require a different product configuration or a controlled enclosure. The rating does not establish outdoor, waterproof or cold-start performance.

Application Fit

The display can be evaluated for:

• Building-lobby information
• Shopping-mall corridors
• Hotel passages and entrances
• Hospital hallways
• Station concourses
• Subway circulation areas
• Government-building notices
• Exhibition guidance
• Event schedules
• Covered transport information
• Retail promotional strips
• Public wayfinding

The two opposing faces are most useful where pedestrian traffic passes in both directions. Installation height, content readability and safe structural support should be reviewed for every site.

The product should not be represented as an outdoor, interactive or network-managed display unless the selected project configuration confirms those capabilities.

Project Customization and Sample Review

Project-specific reviews may include:

• Mounting brackets
• Hanging structure
• Enclosure finish
• Logo and visual identity
• Cable-entry position
• Media-player configuration
• Same-content or different-content playback
• Startup screen
• Local media workflow
• Content-management requirements
• Packaging and labeling
• Power-cable configuration

Custom configurations are generally reviewed from 500 pieces, subject to tooling requirements, material availability and specification scope. Sample and standard-product quantities are confirmed separately.

A production release should follow approval of the mechanical drawing, playback workflow, installation method and sample-validation report.
