Key Features & Engineering Advantages
COB packaging mounts LED chips directly on the board and seals them, removing the weak points of conventional SMD lamps.
Sealed Pixel Surface
Chips are encapsulated under resin, so pixels can't be knocked off during cleaning or contact.
Dust & Moisture Proof
The sealed surface resists dust, humidity, and liquid splashes.
Deep Black Contrast
A matte black surface delivers higher contrast and richer images than SMD.
Ultra-Fine Pitch
Enables very fine pitches from P0.7 for close-range viewing.
Wide Viewing Angle
Uniform colour and brightness even from sharp side angles.
Better Heat Dissipation
Direct chip-on-board mounting conducts heat away efficiently for long life.
Anti-Static & Anti-Glare
Reduced reflections and static build-up for comfortable viewing.
Low Maintenance
Fewer pixel failures mean less downtime and lower service costs.
One Display Technology. Endless Applications.
Where COB LED's toughness and contrast make the biggest difference.
Jewellery & Luxury Retail

Frequently Asked Questions About COB LED Videowalls
What is a COB LED videowall?
COB stands for Chip-on-Board. The LED chips are mounted directly on the circuit board and sealed under a protective layer, instead of being packaged as individual surface-mounted lamps.
How is COB different from SMD LED?
SMD LEDs are separate packages soldered onto the board, which can be knocked off. COB chips are sealed under resin, making the surface tougher, more resistant to dust and moisture, and better at contrast.
Is COB LED good for close viewing?
Yes. COB enables very fine pitches from about P0.7, so it suits boardrooms, control rooms, and luxury retail where viewers stand close.
Can a COB LED screen be cleaned easily?
Yes. The sealed surface can be wiped with a soft dry cloth without the risk of dislodging pixels.
Is COB LED more expensive?
COB usually costs more up front than equivalent SMD displays, but it often lowers long-term costs through fewer pixel failures and less maintenance.
Does Arham supply and install COB LED walls?
Yes. Arham supplies, installs, calibrates, and services COB LED videowalls across India.
