Installing a P1.25 LED display involves multiple steps, from initial preparation to final debugging. Here is a detailed installation guide based on industry practices and technical specifications:
I. Pre-Installation Preparation
Environmental Assessment
Confirm the installation location (indoor/outdoor) and evaluate environmental factors such as humidity, dust, and temperature.
P1.25 displays are suitable for 0℃–55℃ environments and require no fans, ensuring silent operation.
Power and Network Planning
Reserve stable power outlets and network ports.
Use SVV2*1.0 soft-core cables (1-square-millimeter double-strand) for main power connections, with line thickness adjusted based on screen size.
Component Checklist
Screen Body: Includes LED lamp beads, PCB circuit boards, IC driver chips, power supplies, waterproof adhesive, plastic masks, and cabinets/magnets.
Control System: Sending/receiving cards (quantity depends on screen size).
Software: LED control software (provided free with purchase).
Accessories: Computers, audio amplifiers, cooling fans, distribution cabinets, multi-function control cards, lightning arresters, TV cards, LED video processors, and cabling.
Structural Materials: Steel frames, screws, and installation tools.
II. Structural Installation
Frame Assembly
Use square or circular steel tubes to construct the outer frame, ensuring precise alignment.
For large screens, create a "田" (field)-shaped steel frame for stability, with internal dimensions matching the screen size.
Unit Board Placement
Position P10 unit boards inside the frame (note the front/back orientation; the grooved side is the front).
Secure back strips accurately to avoid misalignment during subsequent installations.
Magnet and Unit Board Fixation
Attach magnets to the frame after removing it temporarily.
Reinstall the frame and fix unit boards using screws or magnetic mounts.
Cabling
Connect排线 (flat cables) and power lines between unit boards.
Secure the display power supply and LED control card, ensuring correct polarity (marked on the control card).
Use net cables for short-distance control card connections (e.g., Category 5e cables).
III. Electrical and Control System Setup
Power Supply Connection
Link the display power to unit boards, observing polarity.
Connect control cards to nearby unit boards via power lines.
Control Card Configuration
Use net cables to daisy-chain multiple control cards (input/output ports clearly marked).
The first card connects to the computer’s gigabit network port; subsequent cards link sequentially.
Software Installation
Install the provided LED control software on a computer.
Configure parameters such as resolution, refresh rate, and brightness to match the screen specifications.
IV. Debugging and Testing
Module-Level Testing
Conduct preliminary tests to check for dead pixels or color abnormalities before full installation.
Full-Screen Test
Load test images (e.g., solid white, red, green) to verify color uniformity and pixel functionality.
Adjust settings via software to optimize display quality.
V. Final Installation and Packaging
Screen Mounting
Secure the assembled screen to the steel frame using screws or magnetic mounts.
Ensure horizontal and vertical alignment for seamless拼接 (stitching) in multi-cabinet setups.
Stainless Steel Trim
Install decorative stainless steel trim for aesthetic appeal and structural protection.
Final Inspection
Verify all connections are secure and the screen operates stably.
Key Considerations
Precision: P1.25 displays feature a small 1.25mm pixel pitch, demanding high installation accuracy to avoid misalignment.
Environment: Protect outdoor screens with waterproofing and corrosion-resistant treatments (e.g., salt spray tests for coastal areas).
Cost Breakdown (example for P1.25 displays):
Screen body: ~91,000 RMB/m² (varies by material).
Control system: Depends on screen size (more receiving cards needed for larger/higher-density screens).
Accessories: Computers, cabling, etc. (optional based on user needs).
Steel frame and labor: Can be outsourced or self-installed using provided blueprints.
By following these steps, users can ensure a smooth installation process and optimal performance of their P1.25 LED display.
