Transcript of "Projector power point slide"

  1. 1. Different Projector TechnologiesMark J. Bartlett
  2. 2. Rear ViewPros• Easy interaction with the projection• Ideal for long halls• Can be viewed in illuminated rooms• Great for Command centres• Clean isntallation
  3. 3. Rear View• Cons• Space is required behind the projector itself• Rear projectors are generally more expensive
  4. 4. Front viewPros• Much bigger Image• Wide viewing angle• Allows for keystone correction where the top of the image is wider than the bottom of the image.
  5. 5. Front viewCons• Room lighting must be designed for the purpose of Projector• Projection equipment is often located in the same room as the screen and unless carefully coordinated creates a new source of noise, glare, distraction, etc.
  6. 6. The main types of Projectors• LCD• DLP• CRT
  7. 7. LCD• Liquid Crystal Display• 3 different LCD glass panels for Red, Blue, Green(These transfer the image signal to the to projector.• Cheap home theatre option
  8. 8. DLP• DLP Optical semi-conductor called a DMD chip(Digital micro mirror device)• Consists of millions of mirrors, that work at 10 different degrees in angles.• DMD chips can produce 1024 shades of grey.
  9. 9. CRT• Cathode Ray tube- three tubes commonly called guns, These 3 tubes combine colors to create the image.• Low picture brightness quality• Very cumbersome in size• Can be tuned and refined to a great picture quality.
  10. 10. Light sources• Lumens• Throw• Lamp
  11. 11. Final NotesI will wrap up this powerpoint with a few little reminders, CRT Is terrible but can be usedto watch video feeds.I also would suggest buying a LCD projector for home entertainment uses, and 3d viewingbecomes a lot more affordable.
