Answer
LCD (Liquid crystal Display) uses a solid florescent back light to light up individual pixels in different ratios between red, green, and blue to get your colors. The color black is achieved by blocking the light in a certain pixel, but the problem here is that you can never get true black with LCD screens because there is still a light on behind it making the color actually more of a charcoal gray.
LED tvs work the same way. That is why LED tvs are actually technically called LED-LCD tvs. They use one of two back lighting schemes, and they use LED lights instead of florescent. The first type is edge lighting which uses a light on the four edges of the screen to light all the pixels on your tv. In this type of lighting you still run into color contrast issues and your blacks are never truly black. The other type is called local dimming LED tvs which use a grid of LED lights behind the pixels. This is the best because certain LED lights or cluster of lights can be turned off for your black color while other lights remain on for your other colors. In local dimming LED tvs you get a far better contrast ratio and a better picture quality overall.
Plasma tvs work differently. Behind every pixel there is a chamber that houses the plasma gas and when that gas is excited it causes that pixel to light up. Depending on the combination of red, green, and blue depends on what color you see, and to achieve black the pixel is simply not illuminated at all. This means that your blacks are truly black and your contrast ratio on plasma's is far better then LCDs and about the same (if not better) then local dimming LED tvs.
The pros and cons to each LCD and Plasma are:
LCD Cons: Narrower viewing angle, less contrast, less vibrant colors, and most models use a slower refresh rate causing image ghosting at times.
Plasma Cons: Uses a glass screen so glare is a potential problem in well naturally lit rooms, screen burn can be a problem, they are heavier and not capable of taking much abuse. The life of a plasma is also significantly less than LCD and it uses more energy to run it.
LCD Pros: No glare problems really so they work in just about any room, they use less energy and LED-LCD tvs use even less. They are lighter and are capable of more wear and tear so they are better for commercial applications. Screen burn is not a problem. And the higher end LCDs have good picture quality and refresh rates.
Plasma Pros: Wider viewing angle so every seat in the house is a good seat. Better contrast and more vibrant colors for a better picture quality (In my opinion). High refresh rates so fast pace games and movies tend to look great on plasma's.
I hope that helps you. If I had a choice between the three I would probably go with plasma only because recording technology hasn't really caught up with what LED tvs can do. I often find that LED tvs make everything look fake, and I personally like the picture quality of plasma tvs, but that's just me.
What is a cheap way to make a cute halloween costume?

I am not allowed to buy a costume, so I want something simple and easy to make or find at home. HELP!
Answer
Not knowing how old or young you are i.e. over 10 years but under 16, why not begin with say black tights and a black turtleneck. You can then add accessories in whatever way you like.
A scarf large enough to be a pareo add some costume jewelry and perhaps another scarf as a turban can create an Carribean feeling.
Black tights & black top led themselves to anything goth if you can find the customary black, white, red make up.
Black cat! All you'll need after your black tights & top is an eyebrow pencil for the whiskers and a pair of black or white gloves. Oh yes, you may have some issues creating a tail...but you could always be a Manx cat. If anyone you know has those fake acrylic nails and the glue, you've got claws or goth nails.
Anything you can use as a cape that won't look as if you are wearing a sheet or blanket? Lot's of demonic possibilities there.
Think about a favorite anything: Animal, food, movie or TV idol, anything/anyone. Use your basic palette of matching tights and top to create. It doesn't have to be black. Pink, blue, whatever matches and is appropriate to your theme. Pink Panther, Banana, Cereal Box, whatever.
Time to take stock of what is on hand at home and perhaps at an aunt's house. Just give it back promptly and undamaged.
If you are a boy, go to the closet. Try black slacks, white shirt and black tie. Remember the Blues Brothers? Borrow a similar coat, find a brief case, add shades and a borrowed hat and you're good to go.
It might not be that difficult to do Indiana Jones if you can find the leather-like jacket, hat and whip. Easy to say find a whip but ask around early if that's what you want. Or substitute another item which relates to the Indiana Jones theme.
TAKE INVENTORY of the closets now. Do it with a notebook. Stay away from clothing that could be accidently damaged or stained. Leave those items off your list. Does anyone have any scrap material around? Get permission to use it.
Make sure that you are comfortable physically and mentally with your decision.
Are you going to a party? Trick or Treating? Allow enough room to dress warmly if you're in a northern climate.
One last suggestion. Go online and look at Halloween costumes to get ideas of what you like so that you know what kind of items to be watching for when you do your inventory.
Once you take a deep breath and exhale, you'll be fine.
