Outdoor SMD Screens
Indoor SMD Screens
Flexible SMD Screens
A COB (chip-on-board) LED display bonds the LED chips directly to the circuit board and covers them with a protective layer. It is used mainly for fine-pitch indoor walls viewed from close range.
Typical specifications
| Specification | Typical range |
|---|---|
| Pixel pitch | about 0.6–1.9 mm |
| Surface | sealed, smooth surface that resists knocks and dust |
| Brightness | indoor levels, set by the model |
| Cabinet | often 16:9 cabinets for HD and 4K walls |
| Service | front service on most models |
These are typical ranges across brands; the exact figures depend on the model we quote.
Where it works best
- control rooms
- boardrooms and executive briefing rooms
- TV studios
- luxury retail
What to check before you buy
- Pitch for your closest viewer
- Colour and brightness uniformity across the wall; ask for calibration data
- Whether repairs are done by module replacement
- Compare against fine-pitch SMD for your budget
Frequently asked questions
Is COB better than SMD?
Each has trade-offs. COB is tougher and suits very fine pitches; SMD covers a wider range of pitches and outdoor use. Read our guide below.
