The COB Revolution for LED Screen – Chip On Board Technology
ARECH Fine Pitch COB Series
The latest innovation COB technology, as known as chip on board, with superior energy efficacy, higher contrast and grayscale, enhanced viewing experience, wider viewing angle, and improved reliability, has already imposed a dramatic impact on LED lighting and display industries, and has been widely applied in various indoor commercial environments, like art gallery/ museums, praviate and public cinemas, broadcast statios, control rooms, XR, gaming, etc.
The tiny LEDs are vulnerable to physical impact, moisture ingress, and static electricity. They can be dislodged during shipping, cleaning, or even by insects in an outdoor setting. Furthermore, the manufacturing process creates microscopic gaps between each pixel package, which traps light and reduces contrast.
We offer wide pixel ranges that inlcude from 0.78mm to 0.93mm to 1.87mm, which contributes easily to higher screen resolution, comparing to conventional SMD technology. That is 2K, 4K, 8K quality. COB series therefore, is able to accurately generate wider colour gamuts, which means much more visual details with 16.8 million colors on screen, making them suitable for applications where color quality plays a critical part, such as home cinema, XR, broadcast, and filming or digital production.
The COB Technology directly mounting the LED chips onto the substrate (the PCB) and then encapsulating them under a single, continuous layer of a protective epoxy resin. This creates a completely solid, smooth surface. The benefits are transformative:
- Unmatched Reliability: The epoxy coating protects the chips from physical damage, dust, moisture, and corrosion. COB displays can be touched, wiped clean, and even sprayed with water without risk of damage, making them ideal for high-traffic public spaces, education, and demanding rental environments.
- Superior Optical Performance: The smooth, lens-like surface eliminates light trapping between pixels, resulting in a higher contrast ratio and wider viewing angles. The image is smoother and more uniform, reducing eye strain for viewers.
- Enhanced Thermal Management: The epoxy layer provides a better thermal path for heat to dissipate from the LED die into the PCB, contributing to a longer lifespan and better stable color performance over time.
The fine pitch COB is more complex and expensive to manufacture, its advantages for fine-pitch applications (e.g P0.7, P0.9, P1.2, P1.5, P1.8… ) are so significant that it is quickly becoming the new premium standard.
We having been partnering with upstream top COB Fine Pitch LED Screen for years, Arech offers reasonable, competitive price for this COB product, and develiers long-term carefree service.

Understanding The COB Revolution for LED Screen: A Paradigm Shift in Display Technology
The landscape of high-end visual display is undergoing a fundamental transformation, driven by the COB Revolution for LED Screen. This is not a simple incremental upgrade but a complete re-engineering of how LED displays are built and perform.
At its core, the COB Revolution for LED Screen represents the shift from traditional Surface-Mounted Device (SMD) packaging to advanced Chip-on-Board (COB) technology. For integrators, designers, and end-users in broadcast, corporate, and public venues, understanding this shift is key to specifying displays that offer future-proof performance, exceptional reliability, and breathtaking image quality.
This revolution addresses the longstanding limitations of SMD technology, paving the way for displays that are as robust as they are beautiful.
To appreciate the COB Revolution for LED Screen, one must first understand the weaknesses of the SMD method it replaces. In SMD displays, individual red, green, and blue LED chips are first packaged into tiny plastic housings before being soldered onto the surface of a circuit board. This two-step process creates inherent vulnerabilities.
The packaged LEDs are exposed, making them susceptible to damage from physical impact, moisture ingress, and static electricity. Furthermore, the microscopic gaps between these discrete packages can trap light, reducing contrast and creating a less uniform visual surface.
The COB Revolution for LED Screen elegantly solves these problems by mounting the bare, microscopic LED chips directly onto the substrate and then encapsulating them under a single, continuous layer of protective epoxy resin. This creates a monolithic, smooth surface that is the foundation for its transformative benefits.
The advantages ushered in by the COB Revolution for LED Screen are comprehensive. First and foremost is unmatched physical reliability. The solid epoxy coating acts as a durable shield, protecting the delicate LED chips from dust, moisture, corrosion, and physical touch.
Displays born from The COB Revolution for LED Screen can be safely cleaned and are ideal for high-traffic public spaces, educational environments, and demanding rental scenarios where longevity is critical. Secondly, this revolution delivers superior optical performance.
The smooth, lens-like surface eliminates light-trapping gaps, resulting in a higher contrast ratio, wider viewing angles with consistent color, and a smoother, more uniform image that reduces viewer eye strain—a key factor for control rooms and extended viewing sessions.
Furthermore, the COB Revolution for LED Screen enables true fine-pitch and high-resolution displays essential for modern content. By allowing for ultra-small pixel pitches (from P0.78mm and below), COB technology facilitates stunning 4K and 8K resolutions on direct-view LED walls, making it the perfect canvas for detailed data visualization, cinematic content, and immersive XR/VR environments.
The epoxy layer also provides enhanced thermal management, offering a better path for heat to dissipate from the LED die. This contributes to a longer operational lifespan, more stable color performance over time, and consistent brightness.
While representing a more advanced manufacturing process, the COB Revolution for LED Screen is rapidly becoming the new premium standard for applications where failure is not an option and image fidelity is paramount, from broadcast studios and corporate boardrooms to high-end home cinemas and digital art galleries.
Conclusion: Embracing the New Standard The COB Revolution for LED Screen
These Screens are redefining expectations for durability, image quality, and application versatility. It moves the industry from fragile, discrete components to robust, integrated systems.
The core benefits—extreme durability, exceptional optical clarity, support for ultra-high resolutions, and improved thermal performance—make it an indispensable technology for the most demanding professional and commercial environments.
By choosing a display born from The COB Revolution for LED Screen, you are not just buying a product; you are investing in a reliable, high-fidelity visual platform built to serve as a cornerstone of communication and experience for years to come.
