Indoor COB Fine-Pitch LED Display Series

Detailed Parameters： Brightness：≥ 600 cd/㎡；Viewing angle (H/V)：160° / 140°；Lifespan：≥ 100,000 hours；Grayscale：16 bit；Refresh rate：3840Hz/7680Hz Product Highlights： 1、Ultra-fine pixel pitch — reliably delivers sub-P1.2 or even P0.4-class extremely small pitch with extremely high pixel density, grain-free at close viewing distance. 2、High contrast — integrated black mask eliminates metal-bracket reflection; the black is uniform and deep, delivering a pure dark field with contrast up to 10,000:1. 3、Eye-friendly, anti-fatigue — surface-emission characteristics deliver soft light with low blue-light emissions, effectively suppressing moire and glare and suiting long viewing sessions. 4、Fully sealed protection — no exposed solder joints or lamp pins; the epoxy-resin covered surface delivers moisture-, dust- and static-resistance with front IP rating IP54 or higher. 5、Impact- and knock-resistant — the integrated potting structure produces a smooth, hard surface that withstands routine cleaning or accidental contact, avoiding the classic LED drop-off issue of traditional screens. 6、Efficient heat dissipation — the LED chips contact the PCB directly with low thermal resistance and short heat-conduction paths; long-term operation shows low temperature rise and slow luminous decay. 7、Avoids high-temperature damage — omits the SMD reflow-soldering step, eliminating at the source the risk of LED damage or cold-solder joints caused by high temperature. 8、Extremely low dead-pixel rate — average service life is about 30 % longer than traditional SMD screens; dead-pixel rate is controlled below 1 in 10,000. 9、Low maintenance cost — extreme stability drastically reduces daily maintenance; total lifecycle O&M cost can be reduced by approximately 75 %.
