1. TVs, screens, monitors

2. What’s The Difference??  CRT  LCD  Plasma Display

3. First.. What are displays based on?  Your brain will reassemble a collection of small colored dots (pixels) into a meaningful image.  Your brain will reassemble a sequence of still pictures (frames) shown in rapid succession into a single, moving scene.

5. CRT  Cathod Ray Tube.  Phosphors. http://www.howstuffworks.com/tv4.htm

8. LCD  Liquid Crystal Display.  What are Liquid Crystals? http://www.wikipedia.org/Liquid_crystal Solid Liquid Liquid Crystals

9. http://www.howstuffworks.com/sunglass2.html LCD  Light Polarization.  Liquid Crystals can be oriented using magnetic/electric fields to control light passage. http://www.wikipedia.org/Polarization

13. Active Matrix (TFT)

15. Plasma Display  What’s Plasma? http://electronics.howstuffworks.com/plasma-display.htm http://www.wikipedia.org/Plasma

16. Plasma Display  What’s Plasma?  Neon and Xenon.

18. So… Which Is The best?

19. May be CRT? Pros:  The Cheapest.  Best colors.  More responsive.  Multiple resolutions.  More rugged. Cons:  High power consumption.  High eye strain.  Too big and heavy.  Uneven light output.  Poor focusing across entire screen.  Picture distorted by magnetic field  Burn Ins(screen saver)!!!!

20. Or, LCD? Pros:  Very power Efficient.  Very thin and weigh less.  Less eye strain.  More adjustable.  Environmentally friendly.  Lives longer.  High Resolutions. Cons:  Narrow viewing angle.  Pixelates on low-resolutions.  Can’t produce true black (poor color saturation).  Picture affected by magnetic and electric fields.  Less responsive (Ghosts and Blurs).  Fragile.

21. Then, is it A Plasma? Pros:  No geometric distortion.  Even light output.  Less eye strain.  Perfect focus.  No susceptibility to magnetic fields.  Largest viewing angle.  Small response time. Cons:  Very expensive.  Low Brightness (not for bright places).  Lower resolutions.  Pixelates on low-resolutions.  Even More Burn Ins!!!!!!!!!  Fragile.  Dies sooner.
