LightStream™ DLP® projection vs. 3LCD for Education
LightStream™ DLP® projection vs. 3LCD for Education
The Challenge

Your school, district or campus is looking to upgrade its projection technology and you’re wondering about the differences between DLP and 3LCD technology. What advantages does DLP offer?

The Solution

Most K-12 classroom projectors are based on single-chip DLP (digital light processing) or LCD (liquid crystal display) technology. While up-to-date market share data is hard to come by, in education DLP tends to be more popular due to an overall better price-performance profile, along with these benefits:

  • High brightness
  • High contrast ratio for outstanding readability
  • Very smooth images due to compact space between pixels
  • Very few, if any, dead pixels
  • Rarity of light engine failures compared to other technologies
  • Long lasting out-of-the-box performance over time, without color degradation (which is common with all other projection technologies)
  • Superior color accuracy
  • No filters to maintain or replace
  • Typically quieter and cooler

Based on these benefits, DLP is generally the best value of available projection technologies, offering an outstanding long-term TCO thanks to filter-free designs that eliminate the need to clean and replace filters, the rarity of light engine failures more common to other technologies and consistent high-quality images over time, free from color degradation and dead pixels. As with any technology, DLP has its weaknesses, which can be greatly mitigated or eliminated by choosing a top-quality manufacturer.
