What are the advantages
of LCD Displays?
It's easier to watch. Flat-panel displays like LCDs and Plasmas are significantly brighter
and feature higher contrasts than traditional CRT sets. Which means that an LCD TV will perform
exceedingly well under most ambient light conditions. A brightly lit room won't wash out its
picture, nor will lamplight cause a glare on your television screen. The beauty of these flat
screens is that you don't have to turn out the lights to see the image clearly and easily.
Nor do you have to worry about eyestrain, since neither LCDs nor Plasmas flicker the way old-fashioned TVs do.
And, you can watch TV from almost anywhere in a room since flat-screen LCD displays can have up
to a 160?viewing angle, which means your TV will look good when viewed from any point 80?
in either direction from the center of the display.
One issue affecting the overall quality of the picture reproduced on LCDs has to do with dot pitch.
This term refers to the distance between subpixels of the same color in adjoining pixel triads.
The closer these "dots" are to one another, the sharper the resolution will be. This is especially
true when displaying computer signal images and graphs. And the picture in front of you will be
more realistic and detailed. Higher dot pitches also increase the viewing angles of LCD panels.
Since dot pitch is measure in millimeters (mm), a good rule of thumb is this: Smaller dot pitches
make for sharper images. You generally want a dot pitch of .28mm [" 10,000 pixels/in2 of your display]
or finer.
Note: Plasma displays have long been touted as having wider viewing angles than comparably sized LCD
monitors. But recent improvements in quality have made LCD televisions and monitors comparable to
Plasma TVs with respect to their viewing angles. According to Sharp, a leading manufacturer of LCDs,
the newest generation of LCD displays have just as good viewing angles as plasma sets, but this is
only true of the better brands. In any event, even the best LCD monitors have yet to achieve the
breadth of viewing angles found on typical Plasma monitors.
