What’s COB LED Display?

COB LED display stands for “Chip on Board” LED display. In this technology, multiple LED chips are mounted directly onto a PCB (Printed Circuit Board) substrate, and then covered with a layer of phosphor to create a single lighting module. This results in a dense concentration of LEDs, which enables the COB display to produce high-quality illumination with a very high lumen output.

COB LED displays have several advantages over other LED display technologies. First, because the LEDs are closely packed together, they produce a uniform light output with no visible gaps or seams between the individual chips. This results in a smoother, more continuous image without the “mosaic effect” that can be seen in some other types of LED displays.

Additionally, COB LED displays are highly energy-efficient, due to their high luminous efficacy (lumens per watt). They also have a longer lifespan than traditional LED displays, and require less maintenance, as they do not have any moving parts or components that need frequent replacement.

COB LED displays are commonly used in a variety of applications, such as indoor and outdoor advertising, large-scale video walls, and stage lighting for concerts and other events.
