COB LED Display Solutions for High-End Visual Applications
COB LED display (chip-on-board LED display) is an advanced display technology. It involves directly installing LED chips on a PCB for encapsulation and cutting to form a single module. Compared to traditional SMD LED displays, COB technology offers higher durability, better protection, better heat dissipation, better visual performance, and ultra-fine pixel pitch capability.
Our COB LED Display adopts matte black packaging technology, achieving a contrast ratio of 10,000:1. The high contrast ratio enhances the picture quality, making it more vivid and lively, and providing a stunning visual experience.
COB LED display has become an important display medium for high-end displays, home viewing, high-end meetings, high-end hotels, and brand retail. As a COB LED manufacturer, we have 15 years of industry experience, providing one-stop services covering research and development, design, production, and installation guidance. We have over 20,000 installation cases. Our professional after-sales service ensures the successful completion of your COB LED display project.

Key Advantages of COB LED Display
The COB LED display features a high protection level, high-definition picture quality, seamless and smooth connection without gaps, outstanding performance, and long lifespan, as well as high return on investment.
The COB technology will encapsulate a protective layer on the LED chip, thereby enabling the display screen to have the following protective capabilities: dust-proof, moisture-proof, and shock-proof.
The COB LED display has an extremely small pixel pitch, which enables the following effects: clearer images, better text readability, and smoother visual effects.
Unlike traditional LED displays, COB (chip-level packaging) can offer a more uniform and smoother surface, as well as a better appearance.
High-quality electronic components ensure a service life of over 100,000 hours. The COB LED display is resistant to damage and does not age easily.
The integrated COB design reduces connection points and exposed components. Its protective encapsulation helps reduce damage and maintenance requirements, lowering long-term servicing costs.
The COB technology enables the LED chips to be directly encapsulated on the PCB, significantly enhancing the heat dissipation performance and facilitating stable operation.
Ideal for Mission-Critical Applications
COB displays combine integrated circuit design, stable packaging technology, and strong durability. They are widely used in applications with demanding stability requirements, including command centers, monitoring systems, data visualization, security systems, high-end meetings, and brand retail.
Better Long-Term ROI
Although the initial cost of COB is relatively high, its high-definition image quality, stable 24/7 operation, and long-term benefits can offer greater value. A refined appearance and improved display quality enhance the installation space.
COB LED Display Installation Cases
A business client in Vienna, Austria, needed to equip a meeting room with a high-resolution COB LED display for executive meetings. The main challenge was that due to the close proximity of the attendees to the screen, it was necessary to display electronic spreadsheets, presentations, and video content clearly. Prevision Company configured a 4.8×2.7-meter P1.25 pixel pitch COB LED video wall, providing a native 4K resolution of 3840×2160. Its fine-pitch pixels can achieve high pixel density, ensuring that small text and detailed presentation content are clearly displayed; at the same time, the COB surface packaging technology provides additional protection for the display screens commonly used in meeting environments.
A system integrator in Seoul, South Korea, needed a high-resolution COB LED video wall for the control room to display multiple monitoring windows, data dashboards, maps, and alarm information. The screen must have a backup function. Prevision configured a P0.9 COB LED display with an effective area of approximately 3.456×1.944 meters, featuring a 4K resolution of 3840×2160. Its ultra-small pixel pitch enables operators to clearly read detailed information without the need for a large screen, and the COB LED display is designed with dual backups for power supply and receiving card to ensure long-term stable operation.
A high-end exhibition hall in Kuala Lumpur, Malaysia requires a high-definition indoor LED display for product videos, brand images, and detailed promotional content. The client desires a higher contrast ratio for the display and wants to reduce the risk of damage to visitors when they approach the display. Prevision has configured a 4.8 × 2.7-meter P1.2 COB LED display, achieving a 4K resolution of 3840 × 2160. The COB technology provides a protected display surface, and the fine pixel pitch supports clear product images when viewed closely. The screen’s contrast ratio of up to 10000:1 enhances the vividness of the colors and improves the display quality of the product on the COB LED display.
A corporate auditorium in Doha, Qatar requires a large COB LED display screen for presentations, corporate videos, real-time camera feeds, and executive events. The existing display system was unable to provide sufficient details under the auditorium’s lighting conditions, especially for small-sized presentation text. Prevision has equipped a COB LED display screen with dimensions of 6×3.375 meters and a native resolution of 3840×2160, featuring a pixel pitch of 1.5mm. Its high pixel density direct-view LED technology can clearly display the content. The 600 nits screen brightness does not rely on a dark projection environment. The high refresh rate of 7680Hz for real-time shooting images has no scan lines and offers a better video effect.
A media studio located in São Paulo, Brazil, requires a high-resolution COB LED display for presentations, video recording, and content production based on cameras. Due to the extremely limited maintenance space behind the wall installation, the traditional rear service access method is not practical. Prevision has configured a P1.56 COB LED video wall, with an actual size of approximately 6×3.375 meters and a resolution of 3840×2160 4K. With the front-service configuration, technicians can install and maintain this COB LED display at the front end, thereby reducing the maintenance space required behind the LED wall. The COB packaging process is waterproof, dustproof, and impact-resistant.
