subject: Get Great Tv Watching Experience With An Lcd Tv [print this page] LCD TVs are Liquid Crystal Display Televisions that have become a big craze and huge show stealers due to their crystal clear image display, high resolution, lucidity and great transmission. In an LCD TV, a light source shines through a panel of liquid crystals in order to display an image. To provide a more uniform image, the light is scattered and redirected evenly by a white diffusion panel placed behind the television.
Liquid Crystal Display Televisions use an active matrix LCD which is the most advanced type of LCD. The design of the matrix is based on thin film transistors, commonly known as TFT, which are tiny switching transistors and capacitors arranged in a matrix on a glass substrate.
The LCD TVs help a lot in reducing the requirement for a surplus bandwidth as they have the advantage of a digital video compression. The face of these televisions consists of two transparent layers. Liquid crystals are rod shaped molecules and in response to an electric current they align themselves so that no light can pass through which in turn bends the light.
One of the biggest challenges in enhancing the picture quality of LCD televisions is speeding up the pixel response time which means how fast the colour of an individual pixel can change without blurring. This is very critical for fast moving images so that they don't exhibit motion lag or "ghosting".

These HD TVs smartly replacing old fashioned bulky TV sets from our living rooms. As already discussed, compared to the normal CRT (Cathode Ray Tube) TVs, the HD TV uses digital television signals that reduce the bandwidth usage due to the amazing effects of the digital video compression. Another big advantage of this new technology is that they consume less energy to produce brighter, crisper images.
