High Resolution 600*337.5*38mm P1.875 Indoor LED Video Screens

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 display

The height or Red ,Green and Blue light from light emitting diode(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: 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 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 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 IP65

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
