The Origins of Our LCD Screens and High Definiton Plasma TV in Vintage Computer Monitors

It may be amazing to current computer users who are used to small compact LCD monitors. Not only were initial computer monitors large and cumbersome but that the early monitors used by computer enthusiasts were Cathode Ray Monitors that were not color,

Initial vintage monitors were monochrome - one color only not the brilliant color displays that we take for granted today.

Some of these monochrome monitors were green or orange iridescent. Others were similar to a black and white television that is grey scale.

It is taken for granted now by young computer surfers and gamers that television was always "color", not so.

Initially TV broadcasts were in "black and white ".

Color TV had been developed but the technology but the widespread use did not arise till the early 1970's and even later in some areas.

The broadcasts were seen as black and white on those sets and color on color sets. Color TVs could receive programs that were in the black and white mode as well. Sort of the backwards compatibility of the day.

What then would be the difference between the picture qualities of a television set a monitor has vastly greater resolution than standard TV sets.

The TV sets of that time (as opposed to current high end LCD and plasma high definition TVs) were basically 1950's technology - even the newer color TV sets. .

A monitor's screen display should be stable and of good quality, since the computer user may sit very close to the monitor and spend many hours reading the display.

If the images are fuzzy (low resolution) or waver constantly, you would have a throbbing headache and wavering eyes in no time.

Monitors have knobs to adjust for clarity. On vintage monochrome monitors these usually include a brightness knob which adjusts the illumination of the entire screen, and a contrast knob which makes the letters lighter or darker in relation to the background screen newer color monitors will have additional adjustments for color.

The question will arise - how did the vintage CRT (Cathode Ray Tube) monitors initially handle the color technology which came later and became the accepted standard.

A typical color monitor screen worked in much the same way as a standard CRT television.

The inside of the picture tube is coated with three different phosphors: red, green and blue.

Phosphors are special chemical compounds that glow with characteristic colors when bombarded a stream of electrons.

The phosphor gets "excited" and thanks to the additive properties of the color wheel the different colored lights resulting get mixed and that all types of combinations of the three primary colors result.

The end result is that virtually any color of the rainbow can be produced.

And as for the color white the eyes play a useful trick. When all three colors are mixed together in equal quantities, the eye sees this as "white light".

Finally the sharpness of the CRT color monitor or a TV set's image is determined by three factors: the monitor's bandwidth, its dot pitch, and the accuracy of its convergence.

Although the bandwidth and dot pitch are important to determine a good monitor, convergence is the real measurement.

Indeed we have come a long way from the initial simple vintage monochrome monitors. What we now take for granted with LCD monitors and indeed our high definition TV sets all originated with simple CRT monochrome monitor technology which was merged with the technology and tricks gleaned from the color TV industry.

We should all be grateful. We owe much to "Uncle Miltie".

Eager To Purchase Plasma Screen Television

I have wanted a new plasma television for years now, but up to this point, I did not know what it even was. All I knew is

that plasma televisions are the newest in high tech, and that they have a picture that is out of this world. I do not know

what it was that inspired this craze for a plasma screen television, but it is certainly not the first time that I have had a

serious high tech jones in my life. I have always been a sucker for the latest electronic gizmo, be it plasma screen

television or personal computer, and I guess that this is just simply one more case of the same.

I will not bore you with all of the technical details, but it turns out that plasma screen televisions are really quite as

good as I had always thought. Although it is true that a plasma screen television is not the end all and be all of high tech,

it is also true that it is one of the best ways to go. But lately, I have been questioning my priorities. I have known for

some time that my old color television has to go. It could scarcely even be called a color tv anymore, because the quality of

the picture has degraded so far. But what should I use to replace it with? Do I really have to spend the thousand bucks or so

that it will take to get a nice, big plasma screen television? A couple years ago, I would have said yes without even a

second thought. I would be watching that <a rel="nofollow" href="http://www.BUSINESS-RESOURCE-JOURNAL.COM"plasma screen television

instead of writing this, but then a couple years ago, all Idid was to sit on my fat behind and watch movies. I think that I

can do better than that now, but I do not think that a plasma screen television will really encourage me in the right

direction with my life.

Then again, a new plasma screen television has its advantages. No one ever comes over to my house to watch the big game

because my old tv is so lousy, but with a brand new plasma screen television, I would be the hit of the party. Everyone would

be dying to watch all of the plays in sharp detail on the new plasma screen tv. I guess that, in that way, the plasma screen

television would really improve my life. Maybe I should buy a plasma screen television after all.

The Wholesale Plasma Television Guide

You've finally made the decision to purchase that wholesale plasma television that you have been dreaming of, but you don't want to spend a lot of money. What do you do? Here's a simple, straightforward guide to buying your plasma television at wholesale prices.

There are many advantages to owning a wholesale plasma television. They have great resolution and incredible colour definition. You can finally enjoy that big game or your favourite film on a larger than life screen. But buying one costs a fortune, right. It doesn't have to, if you know the right places- and when- to shop. The first thing that you should do is to check out your local chain television stores, like Best Buys or Circuit City, and see what their prices are. If they are too high for your budget, you might want to sign up to receive their sales fliers, so that you know when they will be on sale.

If you don't want to wait for a sale price to purchase your plasma television, you could check to see if there are any outlet stores in your area. Before you say that you don't want to purchase a refurb- wait. Yes, many outlet stores stock home entertainment equipment which has been returned and repaired, before making its way to the sales floor once more. However, many name brand shops also maintain outlet stores that sell 'dented and scratched' models, at unbelievably low wholesale prices. You can sometimes find great plasma TVs for up to 75% off and they come with a money back guarantee, so you can be sure that if it doesn't meet your standards, you can get your money back.

However, if a 'dented and scratched' model is not for you, try getting some price comparisons online. There are many reputable sites that offer wholesale plasma television comparisons for plasma televisions, like Nextag and Overstock.com. Just type the make and model into the search engine on their sites, and you will see a side by side comparisons of prices.

All you have to do is decide which one you want!
