What is COB LED display?
COB (Chip-on-Board) is an advanced LED technology that marks a breakthrough in the display industry. Unlike traditional LED screens, COB technology allows LED chips to be mounted directly on the circuit board without the need for separate plastic or ceramic packaging. This minimalist design not only optimizes space but also significantly improves overall luminous efficiency and brightness. Thanks to its modern and efficient structure, COB LED screens provide superior display quality, meeting the most demanding requirements in professional display environments.
Luxmage ’s advanced COB LED display module – the ultimate solution for OEM applications that require precision and performance. Engineered with cutting-edge Chip-on-Board technology, Luxmage’s COB LED module delivers high resolution, superior pixel density and seamless projection – ideal for digital signage systems, specialty LED walls and display applications that require high aesthetics.

COB (Chip-on-Board) LED technology allows red, green and blue LED chips to be mounted directly onto a PCB, creating a flat, uniform display surface with exceptionally high pixel density. By eliminating connecting wires and taking up less space, COB allows for narrower pixel pitches, improving resolution and image quality compared to traditional packaging technologies such as SMD or DIP. This is a breakthrough in the LED display field - opening up great potential for reliability, energy efficiency and true color reproduction in modern display applications.

COB technology requires an extremely high level of precision during chip mounting, as each microLED is extremely small and must be aligned absolutely precisely in the predetermined position. Near-zero mounting error is required to ensure image quality.
To meet the ultra-high resolution demands of modern displays such as 4K or 8K, COB technology needs to process millions of sub-pixels in a short time. Therefore, the speed of batch chip transfer is a key factor to optimize production costs and efficiency.
With increasingly stringent standards in the display industry, COB technology offers exceptional reliability. Tight quality control at scale ensures consistent performance, long life, and extremely low failure rates – key factors in professional display applications.
To ensure color consistency and optimize display performance in various application environments, COB Flip Chip technology incorporates advanced surface treatment processes.
Current COB LED display lines offer three superior surface treatment options:

These three options allow for flexible customization for every use, from high-end conference rooms to commercial centers or professional stages.
COB technology directly welds ultra-small RGB chips onto the PCB, allowing for a dramatic increase in pixel density. The result is sharper, smoother images with much higher detail than traditional LED technology.
Smaller pixel pitch means higher resolution. COB LED optimizes pixel density, delivering clear viewing even at close range — ideal for luxury spaces and sophisticated displays.

Thanks to the ability to dissipate heat directly from the chip to the PCB, COB technology helps reduce light degradation and maintain stable brightness for a long time. The larger heat dissipation surface compared to SMD allows light efficiency to always be maintained at an optimal level.
COB LED achieves a static contrast ratio of 13,000:1 to 20,000:1 and a dynamic contrast ratio of up to 100,000:1, delivering vivid images, good depth and excellent clarity in all lighting conditions.

COB is the most advanced packaging technology, which reproduces true and smooth colors. There is no graininess when viewed up close, suitable for applications that require high color fidelity such as museums, conference rooms, and television.

Not limited by the secondary packaging layer like SMD, COB LED displays maintain uniform color and brightness at viewing angles up to 160°, providing a panoramic visual experience, ideal for public spaces and large halls.

The LED chip of the COB LED display is directly soldered on the PCB board, which can dissipate heat directly and quickly. The thermal resistance is low, so the COB LED display can always work at low temperature, reducing heat and power.

The COB LED display is characterized by its effective anti-collision, waterproof, dustproof and anti-static properties. Thanks to the epoxy resin treatment on the surface and the device being completely sealed on the PCB board, the LED chips are not exposed. This makes the display durable against physical impacts such as impacts during transportation or vibrations during installation without causing the lights to fall or be damaged. At the same time, the moisture-proof, dust-proof and anti-static properties also significantly improve the stability and reliability of the device.
The special design of COB LED display increases the heat dissipation contact area when the LED chip is soldered directly to the PCB. The effective heat dissipation ability helps to minimize light degradation and prolong the life of the display. Compared with traditional SMD technology, COB display ensures low operating temperature, contributing to maintaining optimal display performance for a long time.

The COB LED display is designed with an integrated module, eliminating many of the complicated steps and auxiliary equipment required in the SMD packaging process. This not only saves production time and reduces material costs, but also significantly reduces the weight and size during installation. The convenient connection system and low failure rate make maintenance simple, fast and save long-term operating costs.

COB LED screens are capable of achieving extremely small pixel pitches while possessing superior device protection thanks to the technology of packaging chips directly on the PCB, forming a completely sealed structure. Therefore, during transportation, installation or dismantling, the device is not affected by physical impacts and the rate of lamp breakage is almost non-existent. This helps to minimize maintenance costs and increase product life.
Compared with traditional SMD LED screens, COB screens clearly demonstrate superiority in display performance, image quality, durability and operating costs. Many industry experts predict that in the coming years, COB LED screens will occupy more than 80% of the global large-size indoor display market share.
