The height or Red ,Green and Blue light from LED lamps at the proportion of R:G:B=3:6:1

The chips were imported from Optotech Cree/ Nichia are adopted;

Adopted automation solid crystal, light split, bonding wire, bagging;

2. Reliability Test

In order to avoid the potential defects caused in the design and production , we conduct a series of reliability test such as the electronic performance test for the semi-finished products , the anti dust test, the waterproof test , the anticorrosion test( salty spraying test ), the vibration test and thermal shock tester etc.

The reliability test for the semi-finished products: for modules , more than 48 hours aging should be made in the high temperature for all the modules , After QC inspection ok then can package it

The reliability test for the finished products.: After assembling finished modules to the led cabinets and simulating the assembly for the whole cabinets , we keep them aging for more than 72 hours , if no defects found , then we will delivery goods to our customers .

The anti corrosion test : In order to ensure the reliability of anti corrosion of the PCB and cabinet , hence the salty spraying test must be made during the productions

Vibration test : For different kind of screens , in order to ensure the reliability of transportation and moving , therefore , the simulated vibration test must be conducted .

The environment test : The real outdoor environment can ensure the effects of display in factory are the same as the spot effects
