3.Higher Contrast Ratio
4.Higher Contrast Ratio
Advantages of COB LED Display
1. Pack closely
High-density LED arrangement can be achieved, and multiple LED chips are closely arranged on a small area of the substrate, so as to achieve high resolution and fine display effect.
2. No module gap
Module gaps can be reduced between LED pixels, making the gap between adjacent pixels smaller, resulting in a smoother, more coherent image visually.
3. High brightness and contrast
Because the LED chips are closely arranged, COB packaging technology enables higher brightness and contrast, resulting in sharp images in both indoor and outdoor environments.
4. Color consistency
Multiple LED chips can be packaged on the same substrate to achieve better color consistency and avoid color differences.
5. Good heat dissipation effect
The LED chip is directly pasted on the substrate, which can transfer heat more effectively, improve the heat dissipation effect, and help to extend the life of the LED display.
5. Compact structure
The overall size of the LED display can be reduced, making the display more thin and suitable for places with limited space.
Appilication of COB LED Display
The COB technology realizes the conversion from the "point" light source to the "surface" light source, eliminating the pixel graininess. In addition, it can effectively control the brightness of the pixel center, reduce light intensity radiation, inhibit glare, moire and retinal stimulation, suitable for close and long-term viewing, avoid visual fatigue, so in close range scenes, such as meetings, monitoring, charge center, etc., is the best solution.
