Product Overview

Detailed Information

What is COB

COB (Chip-on-Board) is a cutting-edge LED technology where microscopic chips are directly embedded onto the circuit board and protected by a seamless nano-coating. Unlike traditional displays, COB offers a smooth, pixel-free surface that is waterproof, dustproof, and incredibly durable delivering cinema-grade visuals in a sleek,modern form factor Why is COB important for your Poster Display?

Better Protection (Durability)

Since there is no plastic reflector cup, the surface is smooth and solid. It is naturally dustproof, moisture-proof, and anti-collision. You can even wipe it with a wet cloth without damaging the pixels.

Higher Contrast & Clarity

Without the black walls of the SMD plastic cups, COB displays have a much higher contrast ratio (often 10,000:1). The images look deeper and richer, similar to an OLED TV.

No Glare

The epoxy layer acts as a natural diffuser, reducing the harsh glare common in traditional LEDs. This makes it comfortable to view up close—perfect for poster displays in retail stores.

Smaller Pixel Pitch

COB technology allows manufacturers to pack more LEDs into a smaller space, making P1.25 or P1.5 fine-pitch displays possible. This means a much sharper image for high-definition advertising.

Heat Dissipation

Direct bonding helps transfer heat away from the chips more efficiently, leading to a longer lifespan and less brightness decay over time.

Free Standing LED COB Poster

Brilliant full color with high brightness delivers clear, vivid visuals even in bright environments, maximizing advertising impact.

Die-cast Aluminum Body Foldable & Ultra Slim Ultra Light Foldable design for easy storage and transport.

Ultra slim and lightweight body saves space and allows flexible placement.

Wheeled & Movable Design With rolling casters for easy movement, perfect for mobile promotion,events and on-site advertising displays.

Poster LED screen supports remote content updates ,on multiple devices, whether it is an iPad, mobile phone, computer orlaptop, it can be easily operated. Supporting USB and WiFi connections, content publishing is more efficient and flexible.

Specification

What is the main difference between COB and traditional SMD LED posters?

COB (Chip on Board) encapsulates LED chips directly on the PCB board without bracket legs, offering much higher impact resistance, better moisture/dust protection, and zero bead-loss risks compared to SMD. COB also provides wider viewing angles and a smoother, anti-glare visual presentation without pixelated glare.

What pixel pitches are available for COB LED poster screens?

We offer ultra-fine pitch options including P0.93, P1.25, P1.56, and P1.87. For close-up viewing distance (1-3 meters) in indoor locations like retail stores and high-end showrooms, P1.25 and P1.56 are our top-selling models.

How do I control and upload content to the COB poster display?

It supports multiple flexible control options: WiFi, 4G, USB plug-and-play, and mobile APP control (iOS & Android). You can remotely update videos, images, and schedules from your phone or PC anytime, anywhere via cloud management.

Can multiple COB posters be spliced together to form a larger video wall?

Yes. Our COB posters feature ultra-slim bezel designs and precision edge structure, allowing multi-screen seamless cascading (e.g., 6 units linked into a standard 16:9 1080P screen) without visible physical borders.

Is the COB poster screen easy to move and install?

Absolutely. It features an ultra-slim aluminum cabinet and comes equipped with silent castor wheels at the base, making it easy for one person to move. Setup is 100% plug-and-play with no complicated wiring required.

How durable is the screen surface? Can customers touch it directly?

Yes, it is fully touchable and safe. The epoxy resin coating layer makes the display surface IP54/IP65 equivalent against moisture, dust, static, and accidental collisions. It can easily be wiped clean with a microfiber cloth if it gets dirty.

What is the lifespan and power consumption of COB poster screens?

COB technology features optimized heat dissipation directly through the PCB, extending the operational lifespan up to 100,000 hours. Additionally, it consumes up to 30% less energy compared to traditional SMD screens of the same brightness level.

What is your warranty policy, and how do you handle after-sales maintenance?

We offer a 2 to 3-year full warranty. The display adopts a modular design with full front-service support; spare modules and critical tools are included in the shipment. If a unit fails, you can swap out the module in under 1 minute using a magnetic tool.
