Liquid-crystal display televisions, or LCD TVs, are common televisions which use an uncommon displaying method. Compared to the cathode ray tube televisions, the liquid-crystal display televisions are lighter, thinner, and they have a huge variety of sizes available.
If you ask yourself what is the mystery behind the glass sheet, but you do not feel like disassembling your TV, then keep reading! It is quite simple, both the black and colored images filter white light. The amount of light that goes through is controlled by millions of shutters, that open and close constantly. The shutters are arranged in a grid, so the light goes through it only as much as it is allowed. Each shutter, is paired with a filter, and this shutter-pixel couple forms a sub-pixel.
A sub-pixel is much smaller than a normal pixel, so even if you watch carefully from a short distance, you would not know they are there. If you watch your television, you will see the blended colors, that form a pixel, and by changing the intensity of the light, the sub-pixels change, and so do the pixels.
The LCD TVs are so thin because they are made of rod-shaped polymers. These, together, form thin layers. And when these layers gather, the screen is obtained. Because of the nematic liquid crystals, the layers are being kept together.
When you look at a liquid-crystal display television, you probably ask yourself how can all that stuff stay in such a thin room. Well, the truth is that this thing is, somehow, a sandwich. All the things are stuffed in, but they are positioned so everything is alright. The glass sheets, the shutters, everything is so thin that it gets in there.
The polarizing film which the rear sheet starts with, along with the addressing electrodes, the glass sheet, the director, and last but not least, the active matrix components are the lower part of the sandwich. The upper part of the sandwich, or the front sheet, is almost the same, but it has a few differences though. The main difference is the active matrix components, which practically do not exist, because they are replaced by color filters components.
There is a huge obstacle that makes this challenge so difficult, and that is the deposition of the active matrix components. Their failure rate is quite high, this being the reason why the process is a really hard thing to achieve. But this problem was solved, and the prices dropped drastically. Today, many people enjoy their LCD TVs and the good quality images they provide.
