LED Display Manufacturing Process

The manufacturing process of LED displays encompasses a large number of various steps. If you are looking to better understand these steps, our guide below will outline the main procedures going into LED screen production.

LED Display Production Process

Initial Inquiry

We will receive your initial inquiry with your idea, requirements, application, and specifications. Then, we will send you a quote and wait for your confirmation and down payment. Through it all, the process will be started by you and our customer support team.

3D Design

Your requests and the technical concepts necessary to carry out a new order will be carefully examined by our engineers. They will create a detailed CAD model to plan out the manufacturing process for your LED screen.

Structural Prototype Parts

A large LED screen’s frames are custom-made to properly match the features and dimensions specified by the customer. These frames can have cable knockouts, several panels, installation accessories, and anything else that is needed.

Electric Prototype Parts

One of the trickiest and most sensitive jobs in the whole procedure is the production of electronic part such as LED modules and diodes, IC drivers, various circuits, and complete panels that are completely functional and capable of recreating a full-color images.

LED Lamp Baking

Lamp beads are typically baked before use to help ensure that they may be utilized regularly. LEDs are plugged in by placing various-colored diodes into the PCB plate holes to create LED pixel points.


Before pasting the IC, resistors, capacitors, power sockets, and signal sockets, IC SMT requires to brush the solder paste onto the components. The lamp bead surface also requires solder paste brushing, SMT machine patching, and reflowed finishing. The electric capacity and resistance are then mounted on.

Light Testing

This is the initial lighting test; if there are any issues, they will be fixed before moving on to the next stage.

Brush Anti-Paint

After curing, the three-proof paint creates a transparent protective film with outstanding insulation, moisture proof, anti-leakage, shock proof, dust proof, anti-corrosion, anti-aging resistance, and other properties. The three-proof paint also exhibits good high and low temperature resistance.


The manufactured structure is put together using screws, so that there is generally no apparent division throughout the entire unit. The lights are welded in behind the drive plate and bottom plate is mounted to seal everything in place. All of the interior components are organized into a pattern and precisely laser-aligned.

Glue & Mask

Waterproof glue is filled in at this stage as well, before attaching the mask. Lastly, the plastic frame is installed with the LED module, the screws are laid, drive cables jointed, and an SMT patches any welds. The LED modules and the whole display are put together, including a screwed-in mask.


To provide uniform sharpness and colour across the entire LED display, LED panels are calibrated for light and chromatic levels. Photoelectric sensors that measure, modify, and memorise each LED component are employed to do this.

LED Module Testing

Before moving on to the next process, the LED module will be aged for 24 to 48 hours after it has been made to make sure there are no issues.

Cabinet Assembly

The LED module, power supply, receiving card, and cabinet should all be put together and screwed in place.

Final Testing

Testing involves assembly testing and image testing, as well as quality testing. Extensive testing is done after turning on the entire screen. Several test videos are replicated during the image control process to examine chromaticism and its degree of quality. After a 48-hour age test, the LED display is ready for packaging and shipping.


Anything can happen during freight. A high-resistance box is meticulously crafted to safeguard the LED screen during shipment. We will diligently package your LED screen so that it arrives at your location undamaged.


Although the above are the standard and key manufacturing processes, the production may be somewhat different due to custom requests. Contact your LED display manufacturer for more information.
