The most environment friendly LCD TVs
One can really tell the difference between an LCD TV and the other conventional CRT TVs. LCD stands for liquid crystal display. It is possible to a have a material exist in a semi liquid and semi solid state. One can have gases in its natural state or in liquid form. You may wonder how it is possible to make crystals exist in a semi liquid state. When you have educated yourself with the technology behind liquid crystal display, you will begin to appreciate the advantages and disadvantages of LCD TVs. Comprehending on how LCD TV works, will help you decide on the best TV set to purchase for your needs.
The LCD TV is another terrific product that incorporates the liquid crystal technology used in camcorders, digital camera viewing screen, cell phone screen and computer monitors. Basically these types of LCD TV have a very slim design and a very flat viewing screen. What used to be small LCD displays are now changing with new nanotechnology which helps in making larger LCD TV screens.
These screens typically utilize a large flat panel display. The panels are made of 2 sheets of polarized glass-like materials that are glued together. Only 1 layer is coated with a special polymer substance which will hold the thousands of separate liquid crystals. The process of regulating electricity application through each separate crystal makes them either pass or block light in certain proportions results into a series of created images.
A separate light source is needed behind the transparent ‘liquid crystal' panel. An independently housed UV bulb can make the liquid crystal become visible to the viewer. The main reason that these LCD panels are thinner and less power requirements to operate is that they don't require extra electrodes to stimulate phosphors which plasma displays utilize. Another good byproduct of this technique is that no radiation is emitted. The other components needed to from an LCD TV are the Audio/Video input and output connectivity, speakers, standard television controls and a TV tuner. The TV tuner may be analog or digital.
LCD TVs produce clearer pictures which prevent eyestrain. The slim designs that saves room space. They can be mounted just about anywhere you can think of. Since they don't emit radiation, they are eco friendly. They have a wide viewing angle as much as 160 degrees. They can be used also as computer monitors as well as ordinary TVs.
