For outdoor applications or distance viewing, SMD is sufficient and more cost-effective.<\/p>\n<\/details><details>\n<summary>Q: Can COB displays be used outdoors?<\/summary>\n<p>A: Yes, but COB typically has lower brightness (1,000-1,500 nits) than outdoor SMD (4,000-6,000+ nits). For shaded outdoor areas, COB works. For direct sunlight, use high-brightness SMD.<\/p>\n<\/details><details>\n<summary>Q: Are COB displays more expensive to repair?<\/summary>\n<p>A: No. While COB modules cost more upfront, they fail less often. When repair is needed, the entire module is replaced \u2013 similar to SMD. The lower failure rate means fewer repairs over time.<\/p>\n<\/details><details>\n<summary>Q: What pixel pitch COB do I need for a conference room?<\/summary>\n<p>A: For a conference room where people sit 2-3 meters away, P1.5 or P1.9 COB is ideal. The image will be perfectly smooth at normal viewing distance.<\/p>\n<\/details><details>\n<summary>Q: Does IVANLED manufacture COB displays?<\/summary>\n<p>A: Yes.
