Quality Guarantee:
1.The Selection of led
Red,Green and Blue light emitting diode (LED) lamps should be the same grade, height and wavelength on the same displayThe height or Red ,Green and Blue light from light emitting diode(LED ) lamps at the proportion of R:G:B=3:6:1The 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: Before gluing
semi-finished modules , more than 48 hours aging should be made in
the high temperature for all the modules , After QC inspection ok
then can package itThe 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 waterproof test : During the
rainy seasons , the waterproof performance for the outdoor led
display is quite important. the performs high-press water spraying
as well as against the front cabinet to ensure, if waterproof test
in good conditions , therefore , protection rate can reach IP65The
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
