Sharp LCD TVs use liquid crystal display technology. The liquid
crystals in the LCD TV display can be likened to opaque window panes.
However, when you apply power to them, the panes become clear. Sharp LCD
TV displays use a screen that contains thousands of these tiny crystals,
with a light source located behind the screen.
When power is applied to one of the LCD crystals, it opens up--this
allows light to filter through the screen. If there is no power, the
hole closes and the pixel is black. The pixels are placed in a sequence
and quickly turned on and off. This causes the screen to display a
moving picture. This is the theory; in practice, however, what you see
may not always be what you get.
"Dot pitch" refers to the distance between subpixels of the same
color in adjoining pixel triads, and has a major affect on an LCD
picture's quality. The closer the dots, the sharper the resolution. This
is of the utmost importance if you will also be displaying computer
signal images and graphs on your LCD TV screen. Higher dot pitches can
also increase the viewing angles of LCD panels. Although many people
believe that that plasma sets still have a better viewing angle than LCD
TVs, the Sharp Aqous LCD TVs have a viewing angle of 170 degrees, which
is comparable to the viewing angles of plasma sets.
In fact, Sharp recently made television technology history with their
creation of the Aquos LCD TV. Its 65-inch screen is largest LCD screen
on the market. It uses a 16:9 Full-Spec (1080p) HD panel (1,920 x 1,080
pixels) that delivers a high-resolution, high-definition picture of the
same quality as HDTV. The picture quality on the Sharp Aquos LCD TV will
not be affected by room brightness. For those who don't need the bells
and whistles, 20 LCD TVs and 32 LCD TVs are also available.
