In recent years, LED displays have been used more and more in the outdoor field, and the industries involved are more and more extensive, especially in outdoor advertising. Many advertising media have used LED display cards to expand their presence. Share in the advertising market and increase the impact of the company's brand.
LED display production process and process:
Today, LED display screens should continue to innovate technology, improve production processes, produce high-quality and efficient LED display products, seize the market in the fast-developing LED industry, and lead the development trend of the display market. Therefore, Shenzhen Maipu Guangcai LED Display Factory introduced some of the production process of LED display screen for everyone:
1. Plug the lamp: Insert the diode lamps of different colors into the holes of the PCB to form the pixel points. It is often said that the pixel pitch is the distance between adjacent pixels, and the resolution is the number of lamps per unit area. Diodes mainly include wafers, Huacan, Sanan, Silan, Dalian Lumei, American Corey, Guanglei, AXT, AOC, Japan Nichia, etc.; standard specifications for luminescent film are generally 12mell, G and B are 14mell. Note: a. The direction of the lamp, the positive and negative poles should not be inserted anti-b. Do not plant less, mis-plant c. Check the diode itself for problems d.QC detection
2, solder: a. machine over tin b. check whether there is a drop of light c. whether there is a virtual welding d. chamfering e.
3, the installation of the plastic frame: a. shearing b. will be completed the light board and the frame is fixed c.
4. Soldering the lamp board and the driver board: a. Insert the driver board into the lamp board b. Solder the wire with c.QC
5, the school board: a. Use the baffle to align the lamp b. Fix the c.QC test with the lamp cover, remove the cover
6. Detection: a. Access the cable to check if there is any light that is not bright b. Use the universal meter to measure the cause and solve
7. Fix the lamp board: a. Fix the spacer frame with screws b. Fill the glue c. Cover the lamp cover d. Screw the screws to fix the e.
8. Shelf box: a. The module is fixed on the box, from bottom to top b. upper line, connecting c. upper circuit wiring, positive red and black negative d. on the power line, red, blue and green corresponding to positive and negative e. The plastic belt is stuck
9, testing, computer debugging, aging
Conclusion: The LED display has a refined display effect. It must start from various process steps such as material selection, circuit design, temperature rise control, etc. to meet the requirements of use and prolong the life cycle of the product.
