| Full Form | Surface Mounted Device | Glue on Board | Chip on Board |
| Technology | Individual LED lamps (R, G, B) are soldered onto the surface of the PCB | SMD screen with a transparent protective glue layer applied over the lamps | Bare LED chips are bonded directly onto the PCB and sealed with resin |
| Protection | Basic, since the lamps are exposed to dust, moisture and knocks | High, as the glue coating makes it waterproof, dustproof and impact-resistant | High, as the sealed surface resists moisture, dust and collisions |
| Pixel Pitch | Common range from P1.2 to P20 | Similar to SMD, usually P1.2 and above | Very fine, going down to P0.9 and below |
| Image Quality | Good brightness and color, with visible gaps between lamps | Similar to SMD, with a smoother surface but slightly lower light output | Seamless, uniform surface with high contrast and a wide viewing angle |
| Maintenance | Easy, because individual lamps can be replaced quickly | Harder, because the glue layer must be removed before repair | Difficult, as the chips are fixed directly to the board |
| Cost | Lowest | Moderate | Highest |
| Best Use | Indoor and outdoor ads, stages, rental and general displays | Rental screens, outdoor and public areas, places with frequent handling | Control rooms, studios, boardrooms and premium fine-pitch indoor displays |
