What are the relevant contents for wall-mounted installation of indoor LED display screens?

Relevant Information for Wall-Mounted Indoor LED Displays

1. Pre-installation Site Survey

1. Wall load-bearing test: Solid brick walls and concrete walls support direct wall mounting. Light partition walls and gypsum board walls must be fitted with load-bearing steel frames to prevent screen falling.
2. Wall dimension measurement: Measure wall length and width to match the overall size of the LED screen, and reserve space for maintenance.
3. Site environment inspection: Avoid humid areas, direct sunlight and air conditioner airflow. Reserve positions for power sockets and signal wiring.
4. Ceiling height and viewing distance calculation: Confirm mounting height to achieve optimal viewing angle.

3. Steel Frame Fabrication

1. Simple wall mount: Small-size screens can be fixed directly with wall brackets.
2. Standard steel frame: Medium and large screens require galvanized square tube frames for load bearing and leveling.
3. Rear-maintenance frame: Leave a 15–30cm gap between screen and wall as maintenance channel for modules, power supplies and receiving cards.

4. Wall Mounting & Splicing Procedures

1. Fix bottom load-bearing brackets and level them with a level gauge.
2. Hoist cabinets one by one, lock quick connectors, calibrate seams to ensure uniform gap without height difference.
3. Connect power cables and network cables, organize wiring neatly.
4. Install decorative trims to cover gaps between steel frame and wall for better appearance.

5. Electrical & Signal Wiring Standards

1. Separate strong current and weak current wiring with different conduits for power cords and network cables.
2. Complete whole-screen grounding to avoid static damage to modules.
3. Equip main power switch; distribute power evenly to each cabinet to avoid partial overload.

6. Debugging

1. Power on to check brightness and color consistency of each cabinet.
2. Calibrate grayscale and color of the whole screen to eliminate color difference between cabinets.
3. Test signal transmission to eliminate black screen, screen flickering and picture lag.

7. Daily Maintenance Guidelines

1. Regularly check loose wall bolts and steel frames.
2. Keep rear ventilation unobstructed and do not block heat dissipation space.
3. Regularly remove dust and prevent moisture in humid environments to avoid short circuit.
