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.
