How To Install Indoor Fixed Display Screen

The installation of indoor fixed display screens is a highly important project. Its quality directly determines the visual performance, stability, and lifespan of the display. Unlike a simple wall-mounted TV, it involves multiple specialized fields such as structural engineering, electrical systems, signal transmission, and heat dissipation. Here’s how it works, step by step:

Step 1：On-site inspection

1）Wall Installation: Confirm the wall material (concrete, brick, light-gauge steel stud drywall partitions, etc.), load-bearing capacity, flatness, and verticality.

The wall must support the combined weight of the display and its support structure (typically 60-150 kg per square meter or more).

2）Ambient Lighting: Assess the intensity of ambient light at the installation location, particularly whether any windows directly face the screen, as this affects the display’s brightness settings.

3）Maintenance Space: Determine whether front or rear maintenance access is required. This dictates whether a service passage must be reserved between the mounting frame and the wall.

4）Front Maintenance: No clearance is required in front of the screen. Modules can be disassembled from the front using specialized tools, suitable for confined spaces or flush-mounted installations.

This is the most common method currently.

5）Rear Maintenance: A minimum clearance of 0.8-1.2 meters is required behind the screen to allow technicians to perform maintenance from the rear.

6）Access Routes: Measure the dimensions of elevators, stairwells, and doorways to ensure the display cabinet or modules can be transported smoothly to the installation site.

Step 2：Design Confirmation

1) Installation Structure Drawing: Based on the survey results, design or confirm the steel structure support drawings for the display screen. The drawings must clearly specify the steel specifications, welding/connection methods, and wall fixing points (e.g., chemical bolts, expansion bolts).

2) Power Distribution Planning: Plan the wire diameter and routing of the power cables, and confirm the location of the main circuit breaker and distribution box.

A separate, dedicated circuit must be set up for the display screen to avoid sharing with equipment such as air conditioners and high-power lighting.

3) Signal Cabling: Plan the routing of network cables, fiber optic cables, and other signal cables from the control room (where the player is located) to the display screen installation location.

Step 3： Cabinet/Module Installation

Cabinet-style LED Display:
Mount each cabinet individually onto pre-installed hooks or bolts on the steel structure support. Installation typically proceeds from bottom to top and from center to both sides to facilitate adjustments.

Module-style LED Display:
First install magnetic or snap-fit brackets onto the steel structure. Then attach each module individually by magnetically attaching or snapping it into place.

Then check and adjust the overall flatness of the screen.

Step 4:Control System Installation

Install the transmitter card inside the control computer, and install the receiver card and video processor inside the display screen cabinet.

Step 5：Connect the power cable and signal cable.

Step 6：LED Display Screen Debugging

1)Connecting to the Debugging Software: Use the manufacturer’s debugging software to search for and connect the receiving card on the screen.

2)Screen Parameter Settings: Set basic parameters such as the display size (length, width, and pixels), scanning method, and refresh rate.

3)Brightness and Color Correction:

4)Brightness Adjustment: Adjust the screen brightness to a comfortable and energy-efficient level based on ambient light intensity.

5)White Balance Correction: Ensures that the screen displays pure white without color cast and accurate color reproduction.

6)Seamless Layout Debugging

Finally, complete the above steps and LED display screen will work normally.
