only some fifty or sixty years ago it was difficult to imagine a world of modern technologies. And because you can not talk about laptop computers or mobile phones, with a dozen different functions. Then, even a trivial device such as a TV in the house was a luxury item, an object of envy, and the source of the most vivid childhood memories. The world has become more complicated and technically simpler with regard to this constant progress. Now you can without leaving the house, running a web browser on a computer, buy a TV online store in Odessa. And because the choice is not as in Soviet times, not two models!
On the other hand, it is now hard to stumble on the same TV model in two neighboring electronics stores. The range of appliances is staggering, product quality is always on top, and the prices of various models differ in several times. A huge number of domestic and foreign brands offer consumers a variety of devices with additional functions. When you see all this splendor, the eyes just run away. How to make the right choice? What should be guided?
Relationship with all kinds of modern TVs
First of all, decide so, on what the maximum cost you want, and how much cheaper model you seem suspicious. This factor is automatically cut off part of the market offer – both above and below, leaving the band in which both should be sought. It remains only to decide which type of signal outputting surface you prefer.
You can talk about the present, and can be a classic. So it is a cathode ray tube falls into the latter category (or CRT). This type of picture tube for a long time was used in TVs due to the technical impossibility of alternative solutions. CRT TV – it’s always a bulky device with a huge duct on the rear wall. Its only clear advantage is the smoothness of color and natural color transitions, but in other it is markedly inferior technology based on liquid crystals.
LCD and LED TVs are similar in origin and differ only in principle backlight matrix. In one case, light enters from the side, the other – the rear. The latter type is preferable due to the fact that it allows for greater brightness to preserve some contrast. Yes, and the signal thus adjusted three-color and monochromatic LED, in comparison with the first case. Liquid crystal models are compact, have a large wide screen and several popular connectors
The last thing that should be said -. Plasma. This is the common name of the huge widescreen televisions. They use progressive image projection technology, delivering incredible realism to images. Most plasma supplemented with a powerful sound system with a subwoofer for total immersion in the atmosphere of what is happening on screen, turning the room into a true home theater.
