COB contrast SMD led display screen:
1: Production Effeciency
COB :Efficiency and traditional SMD quite solid crystal, wire, suffix point glue, separation, spectral, packing efficiency higher than traditional SMD.
SMD :The production efficiency is lower than COB encapsulation
2: Application
COB: No need for SMT and reflow soldering process, COB light source directly applied on the lamps and lanterns.
SMD :LED devices need to patch, and then fixed by means of reflow soldering on the PCB board.
3: The quality of light
COB:Perspective and easy to adjust, in order to reduce the loss of the refraction of light.
SMD:Discrete device combination point of light and glare.
