COB LED DISPLAY

FLIP-CHIP COMMON-CATHODE COB

16:9 Cable-less Indoor Flip-chip COB LED Video Wall

CABINET SIZE

The LED display model, shape and size can be customized according to your needs.

COB TECHNOLOGY

Inverted COB & Formal COB.

COB Chip Packaging Technology

•Chip-on-Board (COB) Architecture: Directly bonds LED chips to the circuit board, eliminating traditional SMD packaging steps.
This reduces pixel failure rates by 80% and enhances mechanical stability, providing superior resistance to dust, moisture
(IP31 indoor protection), and physical impacts (ideal for high-traffic environments).

•Ultra-Fine Pixel Pitch Options: Models available in P1.2, P1.5, P1.8, P1.9, P2, P2.5, P3, and P4, enabling pixel densities from
69444 pixels/㎡ (P1.2) to 6250 pixels/㎡ (P4) for sharp, seamless visuals even at close viewing distances
(recommended <5m for P1.2-P2.5; 5-15m for P3-P4).

OUTSTANDING PERFORMANCE

Flip chip COB with common-cathode solution,
stable quality energy-saving, and high protection performance.

High Protection Package Technology

Can be cleaned directly with wetcloth, completely solve the damage caused by bumps,
impacts, moisture, salt spray corrosion, electrostatic breakdownetc, suitable for the application of wet or coastal places.

Rugged Environmental Adaptability

•Wide Operating Range: Functions stably in -40℃~70℃ temperatures and 10%-90% humidity (non-condensing),
suitable for extreme indoor environments like cold storage display areas or high-temperature exhibition halls.

•Global Power Compatibility: 110V-240V AC universal input with active PFC, ensuring stable operation across international
markets without voltage converters.

5. Energy-Efficient Operation
Low Power Consumption: 150W/㎡ typical power usage (50% lower than conventional SMD small-pitch screens)
with intelligent power management, reducing operational costs and carbon footprint for large-scale installations.

Product Details
