Digital Outdoor Wall LED Screen Price in Bangladesh

Digital Outdoor Wall LED Screens are powerful, dynamic tools for advertising, branding, and information display. Here’s a comprehensive guide covering everything from benefits and types to key considerations for purchase and installation.

What is an Outdoor Wall LED Screen?

It’s a large, modular display system made up of thousands of light-emitting diodes (LEDs) mounted on a building’s exterior wall or structure.

Key Benefits & Applications

• High Impact Advertising: Captivates attention 24/7 with dynamic video, animations, and graphics.

• Real-Time Content Updates: Change messages instantly from a central computer or remotely. Perfect for promotions, events, news, or social media feeds.

• Branding & Landmark Creation: Transforms a building into a recognizable icon, enhancing corporate identity or venue appeal.

• Revenue Generation: Prime advertising space that can be sold to third parties.

• Public Information & Wayfinding: Used at stadiums, transportation hubs, and city centers for announcements, schedules, and directions.

• Entertainment & Events: For concerts, sports screenings, and public gatherings.

Critical Technical Specifications to Consider

1. Pixel Pitch (P): The most crucial specification. It’s the distance (in millimeters) between the centers of two adjacent LED pixels

   • Viewing Distance Rule: Minimum viewing distance (in meters) ≈ Pixel Pitch (mm) x 2.5.

     • P4-P6: Ideal for high-traffic urban areas, retail fronts, and pedestrian zones (viewing distance 10m+).

     • P8-P10: Common for roadside billboards, larger building facades (viewing distance 20m+).

     • P16+: For very large installations viewed from hundreds of meters away (highways, stadium roofs).

2. Brightness: Must be high enough to overcome direct sunlight.

   • Minimum: 6,000 nits (cd/m²) for most daytime visibility.

   • Recommended: 8,000 nits or higher for areas with intense, direct sunlight. Screens should have auto-dimming for nighttime to save energy and reduce light pollution.

3. IP Rating (Ingress Protection):

   • IP65 is the absolute minimum standard: Dust-tight and protected against water jets from any direction.

   • IP66/IP67 is highly recommended: Protection against powerful jets (IP66) or temporary immersion (IP67). This ensures longevity in harsh weather.

4. Cabinet Design:

   • Material: Die-cast aluminum is best for lightweight, robust, and heat-dissipating cabinets.

   • Weight: Lighter cabinets reduce stress on the building structure.

   • Front & Rear Service Access: Front-serviceable cabinets are essential if the back is against the building wall.

Pre-Installation Checklist & Considerations

• Structural Assessment: MANDATORY. A licensed structural engineer must assess the wall’s load-bearing capacity, wind load resistance, and seismic requirements.

• Permits & Regulations: Check with local authorities regarding:

  • Building permits.

  • Zoning laws and size restrictions.

  • Signage/advertising regulations.

  • Light pollution and brightness curfews (common in residential areas).

• Power & Data: Plan for sufficient electrical supply (often 3-phase) near the installation site. Data lines (fiber optic is best for long distances) must run from the control room to the screen.

• Visibility & Viewing Angles: Analyze site sightlines. Choose an LED product with a wide viewing angle (140-160° horizontal/vertical is standard).

• Cooling & Maintenance: Screens generate heat. Ensure proper ventilation.

• Content Management System (CMS): The software used to schedule and play content. Ensure it’s user-friendly and meets your needs (remote access, playlist scheduling, real-time inputs).

Typical Process Flow

1. Consultation & Site Survey: With a professional LED supplier/integrator.

2. Design & Quotation: Based on specs, they provide CAD drawings, system design, and a quote.

3. Permitting & Approval: Handle legal and regulatory requirements.

4. Structural Reinforcement: If required by the engineer.

5. Framework Installation: A custom aluminum frame is securely attached to the building.

6. LED Cabinet Mounting: Modules are snapped or bolted onto the frame.

7. Electrical & Data Wiring: Professional connection to power and control systems.

8. Calibration & Testing: The entire screen is calibrated for uniform color and brightness.
