LED display production process: 1
LED display production process: 1. Plug the LED lamp into the PCB lamp board, PCB manufacturers have public board to sell, can also design their own, LED manufacturers purchase. 2. The IC, resistor, capacitor and other components are pasted on the drive board. The automatic machine has high efficiency and can also be manually pasted. 3. Install the PCB lamp board and driver into the plastic package (mold shell) and fix them with row pins. 4. Glue pouring outdoor module needs to be waterproof. Pour silica gel into the mold shell and install the mask. It's a semi-finished module. 5. Module aging module aging is the test of LED performance, the general time is 24 hours. 5. Box assembly assemble the module into led box, install the power supply, connect the power cable, network cable and cable, which is the finished box. 6. Screen body assembly: assemble the box into LED display screen, power on, light up, debug and aging (48 hours). 7. Guide the installation, commissioning and customer acceptance of finished product delivery. The lamp board, drive board, module and box need to be tested, and the "first sample" test (to prevent batch quality problems) can control the quality. www.topledcn.com
