What is COB?
COB (Chip on Board) is an advanced LED packaging technology that directly packages LED chips on PCB boards instead of soldering lamp beads separately like traditional SMD (surface mount) technology. This packaging method can effectively improve the stability and display effect of the display screen while reducing maintenance costs.
Technical advantages of COB LED display
1. High reliability and stronger durability
COB packaging eliminates the need for brackets and welding wires, reduces the possibility of solder joint failure, and makes the LED display screen more stable and suitable for various complex environments.
2. Higher protection level
COB technology forms a transparent protective layer on the surface of the LED chip, which can effectively prevent water, dust and impact, especially suitable for outdoor and high-density scenes.
3. Higher contrast and more delicate picture quality
The surface of the COB-packaged LED display screen is smoother, with less light scattering, which can present higher contrast and clearer and more delicate pictures, especially suitable for high-definition small-pitch LED displays.
4. Lower power consumption, higher heat dissipation performance
COB packaged LED chips are directly attached to the PCB board, with a shorter heat dissipation path, which can effectively reduce chip temperature, reduce light decay, and improve energy efficiency.
5. Wide viewing angle design, better viewing experience
The luminous angle of COB LED display is wider than that of traditional SMD, and there will be no problem of too small viewing angle, ensuring consistent display effects when viewed from different directions.
Conclusion
COB packaging technology is becoming a development trend in the LED display industry, especially in the field of small pitch and high-definition display. Its high stability, low power consumption and strong protection performance make it obvious. With the further maturity of technology, COB LED display will be widely used in more application scenarios.
