COB and SMD are currently two of the most discussed technologies in the LED industry.
Many customers assume the difference is only about image quality.
In reality, the differences also involve:
- protection performance
- maintenance logic
- viewing experience
- 長期的な信頼性
Why COB Is Growing Rapidly
COB technology provides:
- smoother surface appearance
- stronger protection
- reduced dead pixel risk
- better anti-collision performance
This is especially valuable in:
- XRスタジオ
- 高級小売
- コマンドセンター
premium conference rooms
Why SMD Still Dominates Many Projects
SMD remains extremely competitive because it provides:
- mature production technology
- cost efficiency
- strong brightness
- flexible application range
特に：
- レンタルステージ
- outdoor displays
- medium-pitch projects
SMD still offers excellent practicality.
Why Fine-Pitch Projects Prefer COB
In close-viewing environments, COB usually provides:
- cleaner black surface
- smoother visuals
- better premium appearance
This becomes very noticeable in:
- broadcast studios
- automotive showrooms
- executive briefing centers
