LCD TV - A trick of light
Probably without thinking about it, use items containing an LCD (liquid crystal display) every day. Every day items such as notebooks, the digital clock, cell phones, microwaves and many more electronic gadgets using LCD technology. Screens LCDs have many advantages compared with the display technology available several others. In a television, are thinner and lighter and draw much less power the old-style tube cathode ray (CRT) TVs and produce much less heat.
You may know that a traditional CRT TV uses three electron guns to produce the image. They are the equivalent of three very fast, precise brush the flash back and forth, painting a moving picture on the back of the screen you see when sitting in front of her.
Like the computer screen and digital photo frames, even if you get in close to a flat screen television that will image is composed of millions of minutes squares known as pixels. Each of them is, in simple terms, a particular red, blue or green that can be lit or off at an incredible speed to make the color image in motion. In an LCD TV, the pixels are activated or deactivated by rotating liquid crystal polarized light.
Take 2 pairs of polarized sunglasses, which must be polarizing for this simple test to work. When the two pairs are at 90 degrees to each other, you can not see through them all.
Using the trick of sunglasses, LCD televisions are able to switch lights pixel colors from time to time to high speed. A big bright light emits light to the viewer. Pixels are against this, each pixel consists of red, green and blue sub-pixels.
A crystal fluid is placed between the filters and it is turned on and off electronically. When lit, the light passing through it is rotated 90 degrees so the Light passes through the filters and making the bright pixel. The transistors that control the pixels on and off very quickly, many times per second, of done.
Thus, unlike traditional and plasma televisions, no phosphors that light up, less power is needed for the operation and the light source an LCD television generates less heat than a Plasma or traditional television. Another great advantage is that the LCD technology emits no radiation from the TV screen.
The original version of LCD TVs in general were of a higher price bracket than plasma models. The prices are far more in a couple today and taking into account the life of LCD TVs is usually much longer than a plasma equivalent model, but use much less electricity to operate, an LCD TV in my opinion is a great option.
