Sophomoric questions
 

Please, do not throw rotten tomatoes at me! ( :

I can easily guess mine are sophomoric questions but, after some honest
efforts, I could not find responses on the Net FOR IGNORANT (at least
in this respect) DUMMIES such as me. I am technically inept and possess
only one traditional, cheap television. I'm thinking, now with the
prices going down and all, to get finally one of those better (that
much I understand!) TVs.

Where should I look in order to begin to understand, in layman's terms,
what is the relationship between the notions of HDTV, LCD, and Plasma.
I looked up the individual terms, but I don't understand which term
implies the other, or whether they are all separate notions or what.

Please be patient with somebody who may not be a total retard in many
other areas, but DOES need patience when it comes to technological
explanations.

Thank you so much.

HDTV just means high definition TV, nothing more.

LCD is Liquid Crystal Display. it's a type of flat panel display
technology.

Plasma is another type of flat panel display. Both come in both SD
(standard definition, or regular TV) and HDTV. Plasma also comes in
Enhanced definition TV, but don't worry about that.

Both have their strengths and weaknesses.

what is the relationship between the notions of HDTV, LCD, and Plasma.

HDTV: High Definition TeleVision. These are televisions that display
a digital television picture with AT LEAST 720 lines of vertical
resolution and in a width to height ratio of 16:9 That means
16*720/9 = 1280 giving 1280 x 720 pixels. Also popular is 1080
lines vertical which gives 1920 x 1080 pixels.

LCD and Plasma are display technologies. LCD is liquid crystal display
which is the display in laptops. Plasma uses ionized glowing gas like
a neon tube, and is typically found in bigger than 40 inch HDTVs.

Yes you have OVERsimplified. Plasma and LCD are types of displays.
Lots of computers, especially laptops have LCDs that are not
HDTVs.

Have you gone to http://electronics.howstuffworks.com/hdtv.htm at How Stuff
Works? I really like this site.

As interesting as it is to go over the if's and buts of the techology, it
always comes down to how much you have to spend and "can you really see the
difference?" You buy the TV that looks the best to you (or your wife) in
your price range.

Can you tell the difference between a TV program shot on film and one shot
with an electronic camera? If not, and most people can't, you won't see the
difference between LCD, plasma, DLP or XYZ displays of the same size. Don't
let the specs, the geeks or the 16 year-old salesman intimidate you into
buying something more expensive if the set next to it looks just as good to
you and it's a thousand bucks less.

Anything you buy will have its upside/downside against some other
brand/quality/price or specs. They all break sooner or later and will be
expensive to repair. Whatever you get probably won't be compatible with
some other piece of gear/technolgy you or your neighbors have. Most of the
features that you pay for you won't need.

It'll be a very long time before TV is 100 percent digital and 100 percent
high def. There's a lot of hardware between the digital camera in the TV
studio and your brand new state of the art HD set at home. Most of that
stuff in between is analog or at best, some kind of digital standard def
that won't be getting replaced just because analog tv transmissions cease in
a couple of years. And by then, a new generation of receiver/monitors will
be out there vexing us.

Go to http://www.vanns.com/shop/servlet/co...128718047092/1 and
scroll down to the articles about TV's. It should help a lot. There
are numerous other articles available, on the internet and in magazines,
that attempt to answer your questions.

Right, laptops are not HDTVs because they are not TVs. It was understood
the OP was asking about TVs, not laptops. My point was to help the OP
understand the hierarchy at play.

These are display technologies, not types of HDTV. There are many
standard definition
LCD televisions.

HDTV is about high resolution (from 1920x1080 to 1280x720) and 5.1 surround
sound as well as broadcast/cable standards to allow it to be sent over the
air or through wires. But you have to have a technology to build a display
for HD.

LCD and plasma are just display technologies to get the pretty pictures.

Two kinds of LCD's - flat panels (like the pc laptop) and rear projection.

The flat LCD panels have fluorescent or LED illumination behind a big LCD
panel with millions of controlled LCD cells shuttering the light to make the
image, LCD RP's have a tiny LCD panel that acts as a controlled reflector
with a big lamp illuminating it and mirrors to get the resulting image on
the screen. LCD RP's are not thin little panels but more like a regular TV
in depth since they have to have those mirrors and stuff.

Plasma is just a big plate of glass with little pockets of xenon gas in it.
Each pocket has an electrode to make the gas glow UV, which is converted to
color by a phosphor coating. You have millions of these little flash lamps
and you have a great big screen.
