What is Micro COB LED Display
A micro COB (Chips on Board) LED display is an advanced display technology that utilizes a cutting-edge LED packaging method for LED light engines. Specifically, COB technology involves mounting LED chips directly onto the substrate on the back of the circuit board, which enhances durability and performance.
To achieve this, ultrasonic welding technology is used to conduct lead bonding of the LED chip, ensuring strong and reliable electrical connections. Afterward, resin glue is applied to encapsulate the lamp position, thereby protecting the LED chip from environmental factors such as moisture, dust, and physical damage.
As a result, micro COB LED displays offer superior brightness, energy efficiency, and longevity compared to traditional LED displays. Additionally, this technology enables finer pixel pitches, making it ideal for high-resolution applications like indoor screens, control rooms, and high-end commercial displays.
Larger Viewing Angle
COB package adopts the class of surface luminescence, so the viewing angle is wider, so that the COB encapsulated micro-pitch LED display screen has a vertical and horizontal bidirectional 170° wide viewing angle, which ensures that any angle of viewing, no color deviation, the images and videos can always be displayed perfectly.

Frequently Asked Questions
1 What is a micro COB LED display?
A micro COB (Chip-on-Board) LED display mounts LED chips directly onto the PCB substrate and seals them with epoxy resin, eliminating exposed pins. This delivers finer pixel pitch, higher brightness, and stronger protection than traditional SMD screens.
2 COB vs SMD LED display — what's the difference?
COB encapsulates chips under a flat resin surface for better heat dissipation, contrast, and durability, while SMD mounts discrete packaged LEDs. COB supports finer pitches (below P1.0) with fewer dead pixels and lower power draw.
3 Is a micro COB LED display waterproof and dustproof?
Yes. Because REISSDISPLAY COB panels are fully sealed with epoxy resin and have no bare pins, they reach front-side IP54 protection against dust, water, oil stains, impact, and static electricity, and the surface can be cleaned directly with water — ideal for high-traffic control rooms and studios.
4 What pixel pitches does the REISSDISPLAY micro COB series offer?
The IFM-COB series covers P0.78, P0.9375, P1.25, and P1.5625, with pixel density up to 1,508,800 dots/m². A 600×337.5mm 16:9 cabinet enables seamless 2K, 4K, and 8K video walls with center-distance deviation under 3%.
5 Where are micro COB LED displays typically used?
Common applications include home cinema, broadcast and TV studios, monitoring and command centers, high-end conference rooms, showrooms, and stage backdrops — anywhere fine detail, wide 170° viewing angles, and no color deviation are required.
6 Does COB LED save energy compared to conventional LED screens?
Yes. Flip-chip COB packaging combined with a common-cathode circuit design cuts power consumption by around 40% versus conventional LED screens, while improving brightness efficiency and heat dissipation for a longer service life.
