FAQ

What is an indoor COB LED display?

An indoor COB (Chip-on-Board) LED display is an advanced encapsulation technology where LED chips are directly mounted on the PCB board. Unlike traditional SMD, COB eliminates the need for bracket packaging, offering higher pixel density, better stability, and superior visual performance for indoor environments.

What is the difference between COB and SMD LED displays?

The main difference lies in packaging and protection. COB vs SMD LED screen comparison shows that COB offers seamless surface protection (anti-collision, dust-proof), higher contrast ratio, and a wider viewing angle, while SMD uses traditional surface-mounted diodes which are more fragile.

What is Flip-Chip COB LED technology?

Flip-chip COB LED display is an upgrade to regular COB. By inverting the chip, it eliminates wire bonding, which significantly improves heat dissipation, increases brightness efficiency, and lowers the failure rate to nearly zero. Ledu Display utilizes premium flip-chip COB for high-end projects.

What pixel pitches are available for indoor COB LED screens?

As a leading fine pitch LED display manufacturer, Ledu offers a wide range of small pixel pitch COB LED screens, including P0.9, P1.25, P1.5, and P1.875, perfectly designed for close-up viewing distances.

Why is a COB LED video wall ideal for control rooms?

A COB LED video wall is perfect for command and control rooms because it delivers a moiré-free, ultra-high-definition visual experience. Its high reliability ensures 24/7 continuous operation with zero downtime, and the soft light emission reduces eye fatigue during long hours of monitoring.

Can COB LED displays achieve true 4K or 8K resolution?

Yes, due to the ultra-fine pixel pitch capabilities (under P1.0), an indoor HD COB LED screen can easily configure into standard 4K, 8K, or even higher resolutions within a limited wall space, delivering pixel-perfect images.

How does COB technology protect the LED screen from damage?

COB technology seals the entire diode array under a smooth epoxy resin layer. This provides excellent 5-layer protection: waterproof, dustproof, anti-collision, anti-static, and moisture-proof, making it much more durable than SMD screens.

Does the COB LED display cause eye strain during close viewing?

https://gemini.google.com/app/00b7f8370f19641b?pageId=none#:~:text=No.%20Traditional%20SMD%20displays%20emit%20point%20light%2C%20which%20can%20cause%20glare.%20COB%20LED%20screens%20function%20as%20a%20surface%20light%20source%2C%20which%20softens%20the%20light%2C%20eliminates%20graininess%2C%20and%20significantly%20reduces%20eye%20strain%20for%20close%2Dup%20corporate%20or%20broadcast%20audiences.

What is the contrast ratio of Ledu’s indoor COB LED screen?

Ledu’s high-contrast COB LED screen features an ultra-black coating technology that achieves a contrast ratio of up to 10,000:1. This ensures deep blacks, vivid colors, and exceptional grayscale rendering even at low brightness levels.

How does COB LED display perform in energy saving?

By adopting common cathode driving technology and flip-chip architecture, our energy-efficient COB LED display reduces power consumption by up to 30% compared to traditional SMD displays, significantly lowering long-term operational costs.

How do you maintain or repair an indoor COB LED display?

Indoor COB displays support full front maintenance. In the rare event of pixel damage, modules can be hot-swapped instantly. For diode-level repairs, the smooth surface allows for precise on-site resin resealing, ensuring seamless visual recovery.

What are the installation options for a COB LED video wall?

Ledu’s indoor COB LED panels support versatile installation methods, including wall-mounted, stacked, or recessed structures. Our slim cabinet design minimizes space occupation and guarantees perfectly flat alignment.

Is it difficult to align COB LED cabinets smoothly?

Not at all. Ledu Display designs its cabinets with high-precision die-cast aluminum with CNC tolerances under 0.1mm. This ensures a completely seamless LED video wall without visible lines between cabinets.

What is the typical lifespan of an indoor COB LED screen?

A high-quality indoor COB LED screen from a reputable manufacturer like Ledu has a rated lifespan of over 100,000 hours under normal operating conditions, thanks to its superior heat dissipation and robust packaging.

Why is the COB LED display price higher than SMD?

The COB LED display price reflects its advanced manufacturing process, higher yield rate requirements, and unmatched durability. While the initial investment is higher, COB offers a lower Total Cost of Ownership (TCO) due to its near-zero maintenance and longer lifespan.

Can I customize the aspect ratio of my COB LED display?

Yes, our standard 16:9 cabinet design allows you to easily build standard 16:9, 32:9, or custom aspect ratio custom COB LED screens to perfectly match your boardroom or studio dimensions.

What certifications do Ledu’s indoor COB LED displays have?

As an export-oriented China COB LED display factory, Ledu's products comply with international quality and safety standards, holding certifications including CE, RoHS, FCC, and ETL to ensure smooth customs clearance and project compliance.

What is the lead time for an indoor COB LED screen order?

For standard fine pitch COB displays, our lead time is typically 15 to 25 working days, which includes rigorous 72-hour burn-in testing at our factory to ensure flawless quality before shipping.

Why choose Ledu Display as your COB LED display manufacturer in China?

Shenzhen Ledu Display Co., Ltd. is a trusted professional manufacturer specializing in high-end LED solutions. We offer direct factory pricing, cutting-edge flip-chip COB technology, comprehensive customization, and 5-star global technical support.
