Small pitch LED COB splicing screen

Our COB small pitch adopts advanced COB integrated packaging technology to directly bond the LED chip to the PCB substrate to achieve true micro-pitch (below PH1.2) point-to-point seamless splicing. The product has excellent anti-collision, moisture-proof and dust-proof properties, effectively eliminating the hidden dangers of dead lights in traditional SMD, and greatly improving reliability. With the characteristics of high contrast, high refresh rate, low brightness and high gray, there is no lag in viewing, the colors are full and realistic, the picture is delicate and without graininess, and it can present rich layers even in low-brightness environments. It is designed for high-end conference rooms, command and control centers, radio and television studios, brand showrooms and other places with strict requirements on picture quality and stability. It is an ideal choice for creating immersive ultra-high-definition visual solutions.

Production Process

Ultra-high density and seamless display

Using chip-on-board technology, LED wafers are directly bonded to the PCB substrate, eliminating the SMD surface mount bracket structure, and achieving pixel pitch miniaturization . The screen has no physical seams and no graininess when viewed from close range.

Full flip-chip COB further breaks through the physical limit, and the welding area is expanded from point to surface, supporting true ultra-fine pitch and adapting to multi-scenario ultra-high-definition display needs.

Surface light source and visual comfort

Converting traditional point light source into uniform surface light source effectively suppresses moiré and glare, and with matte coating technology, it has low reflectivity, achieves wide viewing angle and no color deviation.

Through RG8 Gamma independent correction and low blue light design, it reduces visual fatigue after long-term viewing and meets TUV eye protection certification standards

 

High-quality color performance

Supports HDR high dynamic range, color gamut coverage reaches 125% of NTSC, contrast ratio is increased to 20,000:1, dark field blackness is deeper, and bright details are sharper.

Using 16bit+ grayscale technology, the grayscale level is increased by 32 times, and the 1920/3840Hz ultra-high refresh rate eliminates ghosting, and the dynamic picture is smooth without afterimage.
