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.
LCD

LCD
Light Polarization. Liquid Crystals can be oriented using
magnetic/electric fields to control light passage.

Plasma Display
What’s Plasma?

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)!!!!
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.
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.
