You've seen them advertised online with plummeting prices, you've seen
them at electronics stores like Best Buy and Circuit City, and even at
Sam's Club and Costco. They're flat screen televisions, and they're
going to become more important in 2009, when all of the broadcasters
switch over to purely digital systems.

Flat Screen TVs have stabilized on high quality LCD displays. An LCD
(Liquid Crystal Display) contains millions of cells (pixel elements) that
crystallize when the current level drops below a minimum amount. By
making each cell a triplet, one tinted red, one green and one blue, you
can make a color picture; LCD display typically have fluorescent
backlights on them.

The primary benefit of a flat screen tv for you is that it's got a huge
picture at a fraction of the volume of a conventional Cathode Ray Tube
(CRT or just "tube") television, which more or less has to be at least as
deep as it is diagonally across. Now, if you saw early flat screen
televisions, or computer monitors, or remember really old laptops, you
may recall a phenomenon called "ghosting", where an image would smear
across the pixels, because they couldn't respond fast enough. Modern
flat screen televisions have more or less eliminated that problem by
having response times (how quickly the crystal can change phase from
liquid to solid and back) of eight milliseconds or less.

Likewise, one of the other places where LCD flat screen televisions have
seriously picked up in quality is color fidelity; as the technology has
matured, the ability to get precise color matching has grown by
staggering amounts; one of the keys to this is incredibly fine grained
control over the backlight behind the LCD panels; in some cases, going up
to 1024 levels of brightness, to coordinate with the millions of colors
to give absolutely sharp picture clarity.
So, if you've been hesitant about flat screen televisions before, the
technology has grown up in capabilities while coming down considerably in
price.
