COB Small Pitch LED Screen

The COB (Chip on Board) small-pitch LED display uses advanced packaging technology to directly integrate LED chips on the PCB board, with high density, high reliability and excellent display effects. Its pixel pitch can reach below P1.5, which is suitable for scenes with extremely high requirements for picture quality. COB technology significantly improves the protection performance of the display, with characteristics such as moisture-proof, dust-proof, and impact-resistant, while effectively solving the common problem of lamp bead shedding in traditional SMD packaging. Its surface mask-free design brings a wider viewing angle (up to more than 170°) and higher contrast, and the picture is delicate and grainless. In addition, the COB display has excellent heat dissipation performance, a lifespan of more than 100,000 hours, and supports 7×24 hours of continuous operation. With technical advantages such as low brightness and high gray, no flicker, and high refresh rate, COB small-pitch LEDs have outstanding performance in energy saving, environmental protection, and visual health, becoming the preferred solution for the high-end indoor display market.

Feature and Advantage

High-density integrated small pitch: COB technology uses an exclusive chip-level packaging process to directly bond the LED chip to the PCB board accurately. Compared with the traditional SMD surface mounting technology, it reduces 3 intermediate processes, achieves the industry-leading P0.4-P1.2 ultra-fine pitch, and increases the pixel density by more than 40%. The original bracket-free integrated design eliminates the visual seam of ≥1.2mm between modules, and with the patented optical processing technology, the display screen is viewed at close range without graininess, and the overall consistency exceeds the industry standard by 80%.

Excellent durability: The innovative design without exposed pins and high-hardness epoxy resin sealing process greatly improve the resistance to mechanical shock and vibration, ensuring zero risk during transportation and installation. The integrated sealed structure effectively isolates moisture and dust, and the core protection standard exceeds IP54, easily coping with extremely humid and dusty working conditions. The chip-PCB direct connection technology is used to significantly enhance the electrostatic discharge capability (ESD protection level increased by 300%)

Better display effect: Black PCB background + matte surface treatment, reduce reflection, contrast ratio can reach more than 10000:1. Uniform light emission, horizontal/vertical viewing angle exceeds 170°, no color deviation when viewed from the side. Point-by-point correction technology reduces brightness/chromaticity deviation, and the display is more delicate and realistic.

 

 

 

 

Heat dissipation/power consumption: The chip conducts heat directly to the PCB, with a large heat dissipation area, and the temperature rise is 10-15°C lower than SMD, which prolongs the life. The working temperature is stable, the light decay is small, and the life can reach more than 100,000 hours, which is more durable than the SMD process.
