The screen in a plasma TV is made up of array of pixels, and each individual pixel contains a gaseous substance. The pixels receive charge from a set of electrodes producing photons, giving away ultraviolet light. The light particles generated fall on the pixel wall which is coated with phosphor. When you view the same channel for a long time, or play the same game on your Plasma TV for long hours, the phosphor on the pixel wall may age more in certain areas and start to produce lights of less intensity. At times, with continued lights from the phosphor, the screen is liable to get burn-in, leaving a shadow of an image on the screen. To avoid plasma TV burn-in, you will have to use your plasma TV in a balanced way and avoid leaving the same TV channel or playing the same game for many hours in a row.

For a plasma TV set to show an image, a current of electricity must first pass through the plasma TV set's screen. This will cause the plasma substance inside the pixels to react and cast off ultraviolet rays. Each pixel will glow or dim appropriately to form a perfectly vivid image.

The LCD face consists of two transparent layers which polarize a liquid crystal layer sandwiched in between. The front layer of glass is etched with a grid pattern on the inside surface to form a template for the liquid crystals. Liquid crystals are rod shaped molecules that bend light in response to an electric current; the crystals align so that no light can pass through. Each crystal acts like a camera's shutter, either blocking light or allowing it to pass through. A pattern of transparent or dark crystals forms the image. This same technology has been around for a while, even in such unsophisticated items as digital watches.

Liquid crystal displays have been around for a long time your VCR clock, microwave display, the clock in your room and so on.

The LCD television display consists of two polarizing transparent panels and a liquid crystal solution sandwiched in between. The front layer of glass on the screen is etched on the inside surface in a pattern to form a template for the layer of liquid crystals. Liquid crystals are shaped like rods they bend light when electricity is applied to them this way light can not pass through them. Each crystal acts like a on off switch, either allowing light to pass through or blocking it, the pattern of transparent and dark formed from switching crystals forms the image you see.

LCD monitors have an edge over other monitors as they have better resolution and sleek design. Due to the liquid crystal display technology, an LCD monitor can produce 16.7 million colors, which means, the tiniest of hues can be detected. LCD monitors are sleekly built, so they occupy less space on the table.

LCD TV monitors are a combination of monitors used for computers and a normal television. They have a TV tuner built into them, which can allow them to function as both. They also have audio visual inputs, which can allow speakers and even woofers to be attached.

LCD TVs use an "active matrix" LCD; the most advanced type of LCD. The active matrix design is based on TFT, or thin film transistors. These are tiny switching transistors and capacitors that are arranged in a matrix on a glass substrate, they switch the LCD pixels on and off. In a color TV's LCD, each color pixel is created by three sub-pixels with red, green, and blue color filters.

One of the biggest challenges for LCD TV manufacturers has been speeding up the pixel response time, (how fast an individual pixel's color can change without blurring) so that fast moving images don't exhibit motion lag or "ghosting". This is especially critical for larger-screen LCD TVs, or for LCD TVs on which much of the viewing will be HDTV, or DVD movies.

LCD TV monitors work on the principle of blocking unwanted colors from the white spectrum. Their screens have a large number of pixels, each of which twist and turn at appropriate angles to produce an image. The pixels are illuminated by a thin lamp or a projector LCD. Due to this, the LCD TV monitors can be designed very compactly. They also offer great viewing angles. Some LCD TV monitors can also produce good quality images when viewed at an angle as obtuse as 170 degrees.

LCD TV monitors also have non glare screens. This makes them easy on the eyes, even when viewed very closely. Also, they are not affected by light falling on them. Even in a bright room, the quality of image on an LCD monitor will be as crisp as in a dark room.
