Product Features :
This product is a synchronous and asynchronous shelf screen, which
can be used for debugging,
uploading programs, editing programs, etc. via USB, wifi, 4G, and
network ports. The screen adopts COB
encapsulation technology, which is different from the traditional
SMD surface-mount encapsulation. It
integrates the light-emitting RGB chip in the PCB board instead of
soldering LED lamp to the PCB one by
one. This technology effectively improves the reliability, light
color and protection performance of LED
display screens.
