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. |
