(I) Advantages of Omaha indoor single and double color products:

Omaha material advantages: The use of high-quality LED cores to produce single- and dual-color LED displays has the advantages of large viewing angles, uniform color and non-dead light, low failure rate, and easy maintenance. Standard products, streamlined production. International quality and ultra low price.

SMD3528 SMD lamp beads are more stable than LED dot matrix modules in terms of performance, and are not easy to leak and die.

Reduced maintenance costs. Dot-matrix maintenance requires replacing a module (8 × 8 lamps). Surface-mount maintenance only needs to replace one SMD3528 lamp.

The surface mount unit board is light in weight, reducing the load bearing of the mounting structure. In terms of stitching consistency, the surface-mounted unit board uses an indoor full-color kit. Compared with the dot matrix unit board, the stitching consistency is better and the gap is small (<0.1mm).

As for the driver chip, the surface mount unit board uses constant current drive. Compared with the constant voltage drive of the dot matrix unit board, the constant current can reduce the light attenuation of the LED and make the life of the LED longer.

The full color of the surface mount unit board is processed by machine patch. Compared with the dot matrix unit board, it is manually assembled with high efficiency, good consistency and beautiful appearance.

SMD3528 two-color unit board, the ink color is even, the difference between pure red and green is more pure (compared with the module's yellow-green color), and the synchronous display of graphics and text is better.
