What Is A COB LED Display?

COB LED Display

COB LED (Chip-on-Board Light Emitting Diode) Display is an innovative technology revolutionizing visual communication and advertising. It combines the advantages of both traditional LED displays and surface-mount device (SMD) LEDs, resulting in a unique and powerful display solution. With its enhanced brightness, exceptional color uniformity, and improved energy efficiency, COB LED Display has gained significant popularity in various applications, ranging from outdoor billboards to indoor signage.

A COB LED Display consists of numerous tiny LED chips mounted directly onto a circuit board, forming a densely packed array. Unlike conventional LED displays, which employ individual SMD LEDs, the COB technology eliminates the need to package individual LEDs. Instead, multiple LED chips are seamlessly bonded onto a single substrate, creating a cohesive and compact unit.

The working principle of a COB LED Display relies on the collective illumination of the integrated LED chips. When an electrical current is applied to the display, the LED chips emit light independently, but their combined output forms a unified image or text. The proximity of the LED chips on the COB substrate enables a high pixel density, resulting in a crisp and detailed display.
