COB packaged LED display screen directly integrates and packages the LED chip on the PCB, and uses a special process to form the optical component. It no longer uses a frame (bracket), which effectively solves the problem of producing a larger LED volume due to the inability of separate devices to further reduce the size of the LED. The pain points of LED displays with small dot pitches. COB technology can achieve a point spacing of 0.5mm using the formal mounting process, and a minimum dot pitch of 0.1mm using the flip-chip process.

 

FAQ
 

Q: 1.What is COB LED screen?

A: One type of LED display packaging technology is called COB (Chip on Board). For complete protection of the light-emitting surface, LED light-emitting chips are precisely glued to the module board and connected to driver components via specific media.

Q: 2.Are COB LEDs better?

A: The size and design of COB and SMD LEDs varies significantly from one another.Greater in size, COB LEDs are made up of many LED chips that are affixed directly to a substrate. This makes it possible to produce light at a higher density and utilize space more effectively.

Q: 3.What does COB mean in LED lights?

A: chip-on-board LED
A chip-on-board LED, or COB LED, is a single unit consisting of many LED chips affixed to a thermally efficient substrate beneath a consistent phosphor coating. Anybody who enters a business or residence with track or recessed lighting is probably exposed to light coming from a chip-on-board LED (COB).

Q: 4.What is the difference between SMD and COB LED display?

A: SMD: A SMD is a point light that is produced by several connected point light sources. There are separate SMD devices for glare and point light. COB: A surface-mounted lamp. When compared to SMD, the illumination is more consistent, halo-free, and features a broad, easily adjustable angle beam from COB that eliminates glare and spot lighting.
