Micro Type COB LED Display Flip Chip Common Cathode Ultra Fine Display

Micro-type fully flip-chip common cathode COB display panel

Main features:

• Flip Chip Technology COB flip chip technology means that the electrodes of the flip chip face downwards, and it does not require the wire bonding process of the upright chip. This makes the active layer closer to the substrate, shortens the heat flow path from the heat source to the substrate, has lower thermal resistance, and can greatly improve product stability.
• "Common cathode" refers to using a common cathode method to power LED displays. For products of the same specifications and brightness, common cathode LED displays consume approximately 40% less power than conventional LED displays, resulting in reduced energy consumption.
• Matte Finish
  This product combines a nano-superconducting epoxy resin coating on the screen to ensure consistent ink color over a long period, achieving ultra-high contrast without affecting brightness. The surface uses a matte, non-reflective treatment technology to prevent glare and protect the eyes, bringing a comfortable visual experience.
• High Protection: Compared to SMD LED screens, COB technology offers a higher level of protection. It provides advantages such as waterproofing, impact resistance, moisture resistance, shock resistance, oxidation resistance, salt spray resistance, anti-static properties, and easy cleaning, significantly reducing issues like dead LEDs and poor contact caused by collisions during transportation, installation, and use.
• Low failure rate: The COB process encapsulates the light-emitting chip on a PCB board, and the heat of the chip is quickly transferred out through the copper foil on the PCB board. It also eliminates the need for high-temperature processes such as reflow soldering, which greatly reduces the damage to the light-emitting chip. In addition, the yield rate of the COB process is constantly improving, so the failure rate is greatly reduced.
• The image is softer. COB realizes the conversion from "point" light source to "area" light source, which has better light perception. The area light source emits light without pixelation, making the image softer. It effectively suppresses moiré patterns, resulting in a higher quality display. It is not harmful to the eyes when viewed at close range and is less likely to cause visual fatigue.

Product Advantages:

• Seamless splicing – no visible gaps, creating a truly unified display surface.
• Excellent heat dissipation – efficient thermal management for stable performance.
• Superior flatness – ensures consistent image quality across the entire screen.
• Low temperature rise – keeps the panel cool even during extended operation.
• Long lifespan – built with durable components for years of reliable service.
• Fanless design – eliminates moving parts, reducing maintenance needs.
• Silent operation – zero noise, perfect for quiet environments like home theaters and conference rooms.
• Automatic alarm system – real‑time monitoring with instant fault alerts.
• Low failure rate – high reliability with minimal downtime.
• Safe and secure – designed with multiple protections for worry‑free use

Product Specifications

Strict Aging Test Procedure

Before shipment, every display unit undergoes a rigorous aging test (burn‑in test) . During this process, the screen operates continuously under full‑load conditions for an extended period, simulating real‑world usage scenarios. This critical step ensures long‑term stability, identifies any potential component issues early, and guarantees that your display delivers reliable, flicker‑free performance from day one.

Pre‑Shipment Precision Calibration

Prior to packaging, our experienced engineers perform a comprehensive pre‑shipment calibration on each cabinet. Using advanced optical instruments, we fine‑tune brightness, color uniformity, and grayscale accuracy pixel by pixel. This meticulous process ensures that every unit achieves optimal visual consistency, so your screen arrives ready to deliver stunning, perfectly matched imagery – right out of the box.

Your Assurance of Quality

With our aging and calibration protocols, you can be confident that your display will perform flawlessly upon installation, providing the exceptional visual experience you expect.
