It is to make the box can be taken out from the big screen, which is convenient for on-site emergency maintenance. It is loved by customers. This technology will be necessary for the LED display industry. The development trend.
  3. The PCB circuit board is designed with a perforation: it is convenient to connect the plastic load-bearing face , load-bearing column and the bottom bottom case, and fix the PCB and the lamp bead in the plastic package to prevent the pedal from being damaged.
  5. Interactive technology should be more flexible to capture the movement of controlled objects, making interactive technology more flexible, accurate, error-free, and without delay.
  7. The screen body can be diversified, and it can also be installed vertically. The display effect is better than that of the indoor screen display, which makes the product diversified and feasible.
  9. High load-bearing performance: professional iron box material structure design, lighter weight, stronger structure, bearing capacity of 2-2.5 tons / m2.
