Today there are four types of TVs: kineskopny (elt), plasma, liquid crystal and projective TVs. Each of them occupies the niche in the market and have the advantages and shortcomings. Together with InfoAdvisor.net we will consider in more detail each type of TVs.
Kineskopny TVs (ELT)
The low price promotes a wide circulation of kineskopny TVs.
TVs with the convex screen are less popular, especially among film fans, but cheaper. But at the bigger cost flat screens look beautifully. A lack of ELT-TVs is blinking of the screen though to a dress 50-tigertsovy let out also 100-hertz, but nevertheless at long viewing the fatigue of eyes is noticeable. Couple more of noticeable minuses – influence of magnetic fields on the image and the big sizes. And also you will not find such TVs with a diagonal more than 30 inches. But nevertheless reliability checked by time and big term of work finds the buyers. Besides buyer wide model range of ELT-TVs.
The main advantages of plasma TVs the small thickness of the case and the big size of the screen that gives the chance to place them in any convenient place is. Operation of this TV is based that each point of the screen is the independent shining element. Pluses of technical characteristics in lack of blinking and harmful radiations, and at all this the screen possesses good visibility and does not attract to itself dust. All plasma TVs are equipped with computer entrances, and work on average till 17 years. Unfortunately, in this technology there are also shortcomings. Over time each point of the screen loses the brightness, and maybe in general to fail, especially in those places where there is a constant picture (for example, a logo of TV company). And all this is followed by big consumption of energy, noisy work (because of fans in the cooling system) and rather high cost.
Liquid crystal TVs
The device of the liquid crystal TV are two transparent panels, with the layer of liquid crystals located between them. The picture on the screen of such TV does not flicker because, unlike kineskopny, the picture is output not postrochno, and at once entirely. But thus LCD TVs do not possess sufficient visibility. In spite of the fact that also specify in characteristics to 170 degrees, actually quality of the image is all the same lost at big corners of viewing. Everything also remains a problem with reaction time, i.e. at fast change of the picture the image will be smeared. The size of these TVs reaches 40 inches, but also the price grows about increase in the sizes. Low energy consumption and excellent geometry of the picture speak well for ZhK, to that they do not create electromagnetic waves and do not "burn out" over time. For this reason they can quite be used as displays for the computer.
Popularity of projective TVs grew due to quality and the big sizes of the image.
As a source of creation of the image distinguish the following types: on kinescopes (CRT), on LCD displays (LCD), on micromirrors (DLP).
Projective TVs on kinescopes (CRT)
This type of TVs are more often presented in the form of floor devices. In the lower part projective tubes, speaker systems and electronics, and top – the screen are located. The main characteristic is frequency – 50 and 100 Hz – which directly influence quality of the image. The problem of "burning out" of sites of the screen became a lack of this type of projective TVs that over time puts it out of action. And replacement of this screen costs much very much. But if you are ready to pay such price for quality of the picture with natural flowers and, in addition the big sizes, it is your choice.
Projective TVs on LCD
Advantage this projective in lack of blinking, compactness and rather small cost. They are allocated with the bright big screen with high resolution. But nevertheless there were problems with a natural color rendition, small visibility and spreading of the image. There is also a problem with cooling: noisy fans can be audible in a silent situation.
Projective TVs on micromirrors (DLP)
Popularity of projective TVs on micromirrors (DLP) quite deserved. First of all they attract buyers due to good contrast, image sharpness without spreading, an exact color rendition and high brightness. The main lack of these TVs still remains, service life to several thousand hours, and also rather noisy cooling system. And repair can cost to you in the sum to one thousand dollars.
General advantages to all types of projective TVs the quite inspiring. First, the qualitative sound with a good output power, and in some models is even the built-in subwoofers and systems for creation of volume sounding. Elite models, besides, also are completed with the built-in processor and rear columns. Minus all projective TVs in rather small resource of work of a lamp of illumination and high cost of its subsequent replacement.
If you decided on TV type, among them still it is necessary to choose suitable , the offered different producers.
