In the past, televisions have been heavy and bulky because a regular cathode ray tube (CTR) TV needed the extra room to enable the visible screen and its scanning picture process the room to work. Today we have the convenience of having magnificent color as well as a lightweight television. These lightweight colorful televisions are Plasma, LCD and DLP TV's.
1) How Plasma, LCD and DLP work
Plasma - Florescent light is the sustaining component of a Plasma TV. Florescent is a matter of gas. Launching electrons into the florescent gas causes the electrons to react quickly. The electrons slam into the atoms, it is much like watching a pinball game in action.
In plasma connected to electricity the negative and positive particles are running at each other. While they are running at each other, they are of course bumping into each other. While striking against each other they display an illustrious intensity of ultraviolet light. This is then displayed upon a screen by several layers of glass with contained gas cells and electrode grids.
LCD - Liquid Crystal Diode - Liquid Crystal is one of those amazing things that are in a state of being more than one matter. Liquid Crystal is multi mattered, just as we are. People are solid, liquid and gaseous, yet we are neither. Therefore, it should not be so hard to understand that LCD is multi mattered.
A heat process that by nature transforms liquid crystal into another aspect of itself that is heat changes the Liquid Crystal into a more liquid than solid matter. As a result, anything made of LCD is temperature sensitive. For instance, a computer monitor or thermometers reaction to hot and cold, as people do shiver and swelter. Liquid crystal is used for many things because of its nature when introduced to polymers, such as bulletproof vests and sails for boats.
With the use of electricity, LCD is able to cast a picture by distributing the crystal-clear sequence or design of blocked light molecules. This in turn manipulates light intensity of its pixels that forms upon the colorful screen face.
DLP - Digital Light Processing
Digital light processing uses technology that is based on optical semiconductors. This digital micro mirror device uses tilting mirrors of aluminum, which uses reflected light and a color filter wheel, to create a picture. The mirrors are laid out in a matrix pattern and each mirror equals one pixel. It is like looking at a photo where each piece displays a small square shaped light reflection. The further away you are from the TV screen the more the picture appears to blend together.
The reflected light is directed through a lens and then onto the TV screens producing the images we see.
DLP TV's are not prone to phosphor burn in, nor are they vulnerable to pixilation where the find lines of the pixels separate.
Current DLP TV's are now made slimmer and more lightweight than in the recent past.
DLP technology is used in many ways besides TV screens, which range from business projectors, video walls and home theaters with more experiments in future uses. DLP is also used for commercial entertainment applications and projection systems used for large group viewing.
