Indoor fixed LED screen cabinet with solid metal frame and black LED lamp module profile

Block Indoor Series

An indoor fixed LED screen with rear service access, built on a solid metal cabinet with a black LED lamp module profile. Designed for permanent installations in conference rooms, control centres, retail stores and exhibition halls where a stable, high-resolution image is required.

Product Overview

Block Indoor Series

An indoor fixed LED screen with rear service access, built on a solid metal cabinet with a black LED lamp module profile. Designed for permanent installations in conference rooms, control centres, retail stores and exhibition halls where a stable, high-resolution image is required. Pixel pitch options are 3mm, 4mm, 5mm and 6mm, with a focus on fine heat extraction and structural stability. Cabinet size is selected to fit the wall opening without gaps.

  • Rear service access allows maintenance without removing the screen from the wall
  • Solid metal cabinet with black LED lamp module profile ensures structural stability and minimal light reflection
  • Fine heat extraction performance prevents thermal buildup during long operating hours
  • Pixel pitch options from 3mm to 6mm suit close to medium viewing distances
  • Black module profile reduces visual glare and improves contrast in bright indoor environments
  • Cabinet design allows for tight edge-to-edge splicing with no visible gaps
Application Scenarios

Where This Screen Is Used

  • Corporate conference rooms where the screen must stay mounted and run continuously for meetings
  • Control and command centres requiring stable, long-term display performance
  • Retail stores and exhibition booths with fixed wall-mounted displays for product promotion
  • Museum and gallery installations where the screen is part of the permanent exhibit
  • Education facilities with fixed classroom or lecture hall displays
Buyer Fit

Who It Is For

  • AV system integrators installing permanent indoor LED walls in commercial buildings
  • Corporate facilities managers needing low-maintenance, long-life display solutions
  • Exhibition contractors setting up fixed displays for trade shows and events
  • Retail chains deploying branded screens in flagship stores and shopping centres
  • Government and institutional buyers specifying indoor display systems for public spaces
Problems Solved

Problems It Solves

  • Screens that degrade over time due to poor heat dissipation in enclosed wall spaces
  • Rear service access blocked by wall mounting, requiring full removal for repairs
  • Visible seams or gaps between cabinets due to loose alignment or weak cabinet structure
  • Glare from bright LED modules interfering with image clarity in well-lit rooms
  • Cabinets that wobble or shift after installation due to weak frame or poor module alignment
Engineering

Technical Features

  • Solid metal cabinet with black LED lamp module profile for structural rigidity
  • Fine heat extraction performance through cabinet design and material choice
  • Rear service access for module and power supply replacement without wall removal
  • Pixel pitch options: 3mm, 4mm, 5mm, 6mm for matching viewing distance
  • Cabinet edge-to-edge splicing with no visible gap line
  • Black module profile reduces ambient light reflection and improves contrast

Build Materials

Materials

  • Solid metal cabinet frame
  • Black LED lamp module profile
  • High-stability metal components for cabinet structure
  • LED lamps with fine heat extraction design
Manufacturing Process

How This Screen Is Built

  1. SMT placement of LED lamps and driver ICs on the module PCB
  2. Reflow soldering followed by automated soldering inspection
  3. Auto drying and module ageing test before assembly
  4. Cabinet assembly with module flatness alignment on the assembling line
  5. Full screen installation test and screen ageing test before packing
Inspection and Testing

Quality Control

  • Soldering inspection on every module after reflow
  • Module ageing test to catch early-life lamp and driver failures
  • Screen installation test with the cabinets built up as a full wall
  • Screen ageing test on the assembled wall before it is dismantled for shipping
Customisation

Customisation Options

  • Pixel pitch selected based on the intended viewing distance
  • Cabinet size chosen to match the wall opening without gaps
  • Splicing method adjusted for edge-to-edge alignment
  • Black module profile maintained for consistent visual performance
  • Rear service access preserved in all configurations
Comparison

How It Compares With the Alternatives

Front service indoor screenRear service is more common in fixed installations and avoids the need for front clearance, but front service allows access without removing the screen from the wall
Indoor rental cabinetThe fixed cabinet is heavier and not designed for repeated rigging, but it has better heat extraction and structural stability for permanent use
Transparent indoor screenThe block indoor series offers higher resolution and better brightness than transparent screens, but trades off visibility through the screen for image quality
Specifying and Operating

Use Guide

  • Choose pixel pitch based on the closest viewing distance, not on cabinet count
  • Confirm the wall structure can support the cabinet weight before selecting the largest size
  • Ensure rear access is clear for maintenance and module replacement
  • Use the provided mounting hardware and avoid over-tightening to prevent cabinet deformation
  • Request a screen ageing test at the factory and review the wall in the showroom before shipment
Questions Buyers Ask

Questions About the Block Indoor Series

Can the screen be serviced from the rear?

Yes. The cabinet is designed for rear service, allowing modules and power supplies to be replaced without removing the screen from the wall.

What pixel pitches are available?

Available pixel pitches are 3mm, 4mm, 5mm, and 6mm, selected based on viewing distance.

Is the cabinet solid and stable?

Yes. The cabinet uses a solid metal profile with a black LED lamp module for structural stability and minimal light reflection.

Does the screen have good heat extraction?

Yes. The cabinet design supports fine heat extraction to prevent thermal buildup during long operation.

Can cabinets be joined edge to edge?

Yes. Cabinets are designed for edge-to-edge splicing with no visible gap line.

Is the black module profile effective for reducing glare?

Yes. The black module profile reduces ambient light reflection and improves contrast in bright indoor environments.

Can I get a test screen before shipment?

Yes. We offer a screen ageing test and pre-shipment customer review in our in-house showroom.
