COB Small Pitch Display

Stonbel COB high-definition full-color large screen adopts a color management system with the advantages of self-illumination, high contrast, high color gamut, ultra-long service life, high refresh rate, and ultra-high pixel density. Under the sunlight, the screen surface content can be presented in high-definition, with a high degree of gray control. It can use 1024~4020 levels of gray control to clearly and realistically display more than 16.7M colors, ensuring the ultra-strong stereoscopic effect of the screen; Use modern digital processing technology to process video, mainly select the technology distribution mode for scanning, design and display modular, adopt static constant current drive, automatically adjust brightness, achieve high fidelity of the image, and improve the clarity of the image; It has high protection performance, indoor low brightness eye protection, outdoor IP68 protection grade, waterproof, dust-proof, moisture-proof, wear-resistant and impact-resistant, and is mainly used in command center, dispatching center, urban traffic, data center, large conference room, enterprise exhibition hall, etc.

Super protection, high stability

Using unique D-COB packaging and technology, it can be wiped and cleaned directly;

Secondary packaging technology, bearing vertical pressure of 100N/cm², stronger pressure resistance and higher protection level;

Epoxy resin glue is encapsulated and cured, the surface is smooth and seamless, super protection, moisture-proof, dust-proof and anti-static.

Super high contrast ratio for true color reproduction

125% NTSC broadcast-grade color gamut, 281 trillion colors, more delicate and richer colors

8000:1 ultra-high contrast ratio, restore true color

The image display is softer and enhances the visual experience

The area-type packaging technology makes the LED module emit light evenly, and the horizontal and vertical viewing angles are 170°/170° without color cast, effectively eliminating moiré.

The use of matte coating secondary optical diffusion technology can effectively reduce the intensity of light radiation and reduce the impact on the viewer's retina.

Excellent heat dissipation and energy saving effect

Directly connected to the circuit on the PCB, the heat conduction path is the shortest, the thermal resistance value is the smallest, and the heat dissipation effect is better than that of SMD discrete devices;

Adopt common cathode design, lower heat generation and more energy saving.
