| Technology |
LED chips are individually mounted on PCB |
SMD LEDs coated with protective epoxy layer |
LED chips directly bonded on PCB surface |
| Protection Level |
Standard protection |
Enhanced protection (anti-collision, dust, moisture) |
Highest protection (fully encapsulated surface) |
| Surface Durability |
Moderate, LED beads exposed |
Improved resistance to impact and humidity |
Very high durability, strong physical protection |
| Pixel Stability |
Mature and widely used |
More stable than SMD in harsh environments |
Very stable, fewer dead pixels in fine-pitch applications |
| Maintenance |
Easy module-level repair |
Slightly more complex due to glue layer |
More complex repair, module replacement preferred |
| Heat Dissipation |
Good |
Slightly reduced due to glue layer |
Excellent thermal integration design |
| Viewing Experience |
High maturity, wide viewing angles |
Smoother surface, reduced pixel exposure |
Ultra-smooth surface, excellent close viewing |
| Cost Level |
Lowest |
Medium |
Highest |
| Best Use Cases |
Standard indoor LED screens |
High-traffic areas, rental LED, semi-protection environments |
Fine-pitch LED, high-end display, XR, control rooms |
