The production process of LED display screen

The production process of LED display screens generally includes the following steps:

1. Laser cutting: Hang the LED chip on the blue film and use laser cutting technology to separate the chip into individual LEDs.

2. Welding: Weld a single LED onto a circuit board to form an LED bead. LED chips are usually composed of dozens or even more to form a chip.

3. Encapsulation: Add a casing to the LED beads to protect the LED chip and circuit board.

4. Module production: Combine and package multiple LED beads to form an LED display screen module.

5. Screen production: Install LED display screen modules on a metal frame and add components such as controllers and power supplies.

6. Assembly and debugging: After completing the screen production, assembly and debugging are required to test whether the screen can display and respond to signals normally.

The above is the usual production process for LED displays, and there may be slight differences among different manufacturers and equipment.
