In an LCD TV or "transmissive" display, a light source shines through a section of liquid crystals so that you can display a graphic. A white diffusion panel behind the LCD blows and scatters the light evenly to offer an even more consistent image than most competing technologies.

The LCD experience includes two transparent layers which polarize a crystal layer sandwiched in between. The top layer of glass is etched with a pattern on the inside surface to create a theme for the liquid crystals. Liquid crystals are rod shaped elements 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, both blocking light or and can move across. A structure of clear or dark deposits forms the image. As electronic watches this same technology has been around for awhile, even yet in such unsophisticated objects.

LCD TVs use an "active matrix" LCD; the absolute most advanced form of LCD. The effective matrix design is dependant on TFT, or thin film transistors. These are little switching transistors and capacitors that are organized in a on a substrate, they move the LCD pixels on and off. In a TV's LCD, each color pixel is done by three sub-pixels with red, green, and blue color filters.

One of the greatest problems for LCD TELEVISION companies has been quickening the pixel reaction time, (how fast an individual pixel's color can transform without blurring) to ensure that fast moving pictures do not show action lag or "ghosting." That is particularly important for larger-screen LCD TVs, or for LCD TVs which much of the viewing will be HDTV, or DVD movies.

A significant difference between LCD engineering and Plasma is an LCD screen does not have a coating of phosphor dots; LCD TVs color is established through the usage of filters. That keeps picture burn-in from being a problem--- that is good news in-particular for those who might use a video gaming program or PC on their TV. Yet another good thing about buying a LCD TELEVISION may be the energy efficiency with this technology. LCD TVs generally consume 60% lees energy than comparably sized tube-type, direct-view TVs.

In most methods really matter there is not much variation between LCD TVs and Plasma TVs. Both of the very popular forms of flat screen TVs are slender enough to be placed virtually anywhere, and both create pictures that are amazingly clear, sharp, and brilliant. The most notable huge difference is screen size. The majority of LCD TVs have a display dimension measuring 30 inches and smaller. Plasma TVs are, for the most part, uninhibited by measurement constraints.

Basically, LCD and Plasma TVs are different ways to exactly the same result since the superior images are created by both using radically different technology. e39 lowering springs discussions
