I can explain the process of manufacturing and installing store LED screens in detail. The entire process is generally divided into four stages: design, manufacturing, debugging, and installation. Here's a step-by-step explanation:
1️⃣ Design Stage
LED screen production begins with design:
Determine screen size and resolution
The screen's length and width are determined based on the size of the storefront, viewing distance, and budget.
Resolution is determined by the pixel pitch (P, in mm):
P1.25~P2.5mm: Close-range viewing (e.g., in-store advertising screens)
P3~P6mm: Medium distance (shop windows, storefronts)
P10 and above: Long distance (outdoor billboards)
Select LED type
SMD (Surface Mount Device): High pixel density, clear image, suitable for close-range viewing
DIP (Dual In-line Package): High brightness, outdoor sunlight resistance, suitable for long-distance viewing
Determine functional requirements
Indoor/Outdoor
Waterproof and dustproof rating (IP65, IP67, etc.)
Whether it supports dynamic video playback and remote control
2️⃣ Manufacturing Stage
The manufacturing stage mainly involves combining LED modules, control systems, and structures into a complete screen.
LED module manufacturing
LED beads are soldered onto the PCB board → driver chips are soldered → the brightness and color of each LED bead are tested.
LED modules usually have standard sizes (e.g., 320×160mm), and multiple modules are spliced together to form a large screen.
Assembly of the casing/frame
The casing is made of aluminum alloy or steel structure (thickness and strength are determined by the screen size and outdoor conditions).
The LED modules are fixed inside the casing, ensuring flatness and stability.
Installation of the control system
Includes LED control card, receiving card, power module, and connecting cables.
The control system is responsible for screen refresh and playback, and signal transmission and power connections are usually pre-tested.
3️⃣ Debugging Stage
After the screen is manufactured, functional and display debugging is performed:
Single module testing
Check if the brightness and color of each module are uniform.
Whole screen splicing debugging
Check the spliced screen for bright spots, dark spots, and color differences.
Adjust brightness, refresh rate, and color correction.
Software testing
Install playback software and test the display effect of pictures, text, and videos.
Check if the remote control or timed playback function is working properly. 4. Installation Phase
Installation involves securely fixing the screen in its designated location within the store, ensuring both safety and aesthetics.
Bracket or Mount Installation
Large screens typically use wall-mounted or freestanding brackets, requiring attention to load-bearing capacity and wind resistance.
Outdoor screens require waterproof covers and protective netting.
Module and Wiring Connection
Each LED module is installed into the cabinet and connected to the power supply and signal cables.
Ensure seamless splicing between modules.
Overall Debugging and Protection
After installation, perform a comprehensive test to confirm uniform brightness and consistent color.
Outdoor screens require rain and dust protection (e.g., silicone sealing, waterproof cable conduits).
Fixing and Acceptance
Confirm that the screen is securely fixed and free from looseness.
Complete operational training (software playback, remote control).
✅ Summary
Design: Size, pixels, LED type, functional requirements
Manufacturing: Module welding → Cabinet assembly → Control system installation
Debugging: Brightness, color, splicing, software functions
Installation: Bracket fixing → Wiring connection → Full screen debugging → Protection
