To select the TV – no small thing. There was a time when buying such a device is flush big holiday or event. Today we will tell you what to look for when purchasing your TV. Listen to our advice, and you will not be disappointed when you come home after a hard day, he fell on his sofa waiting for quality pictures and favorite program.
Probably no appliance has not been awarded such a huge attention of marketers different companies. It is interesting that for 20 years he kinescope three times already changed shape. First was a classic screen layout in the shape of a sphere, then in the early ’90s, the company SONY marketers have come up with an ingenious advertising campaign. Client strongly explained that the screen must necessarily be flat and only with the CRT, you will get excellent picture quality. In 2012, there were fancy and expensive TVs in the form of a concave sphere. In principle, for all these 20 years by changing the shape of the screen itself is advertising rhetoric has not changed.
Marking
himself to understand the marking of the TV is almost impossible. Each manufacturer introduces their values, figures and things like that. For TV unified labeling does not exist. If you have decided on the brand, visit the company’s website and carefully read their values, which are present in the product name. The marking indicates parameters such as size, year of production, series.
Country of origin and “gray TVs»
We on the market a long time ago no technology in Japan. Most of all the equipment is made in China. China – it is now a global factory that assembled anywhere and for anyone; there collect Sony equipment, Aple, Toshiba, and many more famous brands. A different situation is with LG and Samsung Korean firms. Televisions these brands can be found European assembly and assembly in Korea. In general, you should not puzzle over where he was going. What is more important. Pay attention to the price of the TV, if the price is significantly lower, it is likely that you are trying to sell illegally vvezёnny television, “gray”. These televisions tend to the European assembly, Poland or Russia. What you are threatened with the purchase of the TV? Quite simply, a guarantee on these TVs are not covered. Even in the company’s service center you absolutely refuse warranty repair. This does not mean that the machinery will break or be of lower quality. Many people buy a “gray” products, saving seriously, and use such devices for many years. Rather, it is as lucky.
What brand to buy
You should understand that now the market prevail two companies manufacturers matrices for TV – a Korean firms Samsung and LG. So theoretically, no matter what you buy, you will get the TV on the matrix from LG or Samsung. There is an option to buy a TV on the matrix from Sony Sharp. So bother to any particular company is not worth it. Here is a matter of design.
Resolution and Frequency
With this indicator, in principle, too, everything is not difficult. The higher the resolution – better. Now the standard is to allow Ful HD 1920 * 1080. TVs with lower resolution makes no sense to buy, picture quality will not be it is not really suitable for viewing from close range. The best purchase is to buy a 4K resolution. Of course, content with such a resolution a little, but soon the situation will change. In TVs with a resolution of difficult to discern individual pixels even with a small distance, which is very pleasing, especially if the television is purchased for a small kitchen.
Many manufacturers write on their products, it is sky-high frequency performance in the 200, 300, there even at 600 hertz. Now, those numbers are irrelevant to the refresh rate (scan) of the matrix itself. Absolutely all manufacturers are capitalizing on this indicator. In fact, it is only the most frequency backlight. This technology helps the “fool the eye”. Picture really turn out fine. But the real difference between 100 and 600 hertz you do not notice it. About the real rate of the matrix can be found on specialized forums.
Type of matrix
This is the most important, what you need to pay attention. Today, there are more than 10 variations of the matrices from different manufacturers. We will look at the most basic.
TN matrix. Once this type of matrix was the most common, but with the development of other more advanced types, TN gradually leave the market. The advantage of such a matrix is the high price and response time, thereby in dynamic scenes is no loop from the image and blur. Minus – small viewing angles and color reproduction is mediocre. TV on these screens are very cheap segment and stop for a more detailed description makes no sense.
IPS. Matrix, which is ideal for TV medium segment
Advantages:. Wide viewing angles
Disadvantages:. High black level (~ 0.16 nits), a large response time
.
Installed in TVs LG 3-9 series (ie, virtually all without division by levels), Philips 4, 6 series of (mostly), Panasonic different variations and many others. If the screen is protected by glass is not flexible, then check availability ips on TV, you can: Swipe your finger gently from the matrix, applying slight pressure – if there is a trail – it means not ips
S-PVA (Samsung production).. Matrix classes for TV above the
Advantages:. Deeper black (0.05-0.1 nits depending on the implementation of the backlight)
Disadvantages:. Smaller than the IPS, the angle of view, the worst, than the IPS, color rendition.
Installed in TVs Samsung 7-8 series, Sony 7-8 series, Philips 7-8-series, and some others.
UV²A (manufactured by Sharp ). A new type of matrix. Soon the technology as it is necessary to break in, and indicators on the TV so the matrix will increase
Advantages:. Angles greater than that of S-PVA (but less than in the IPS). The deepest black level (0.02 – 0.06 nit)
Disadvantages: Sharp produces them in insufficient quantities
Installed in TVs Philips 9 series and popular series of Sharp..
plasma
With these words connected a lot of myths and misconceptions. Any uninformed seller is required to tell you that the plasma is outdated. This is due to a set of stereotypes and problems have occurred.
The image is formed using the phosphor glow when exposed to UV rays. Each plasma cell is an independent light source, so TV does not require a backlight. Previously, plasma TVs have a very large thickness and cell size, so we were very cumbersome and diagonal Full HD began with 50-60. “Now, the thickness of the modern plasma TV does not exceed 3-4 cm, and begin with a diagonal 42″.
In plasma TVs do not have different types of matrices with the marketing names, but there is a generation of panels
Now the plasma is almost superseded LCD-TV and its production has been only 3 companies:. Panasonic, Samsung and LG (and, own development have only the first two). This is due to the unprofitability of production, competition from LCD TVs and their popularization. But plasma holds the first position in the large diagonals
In the plasma is characterized by:.
Burn (burn) the problem is practically solved. To “burnt out” cell, you need to leave a still image contrast at least a couple of days (perhaps more precise data are not known to me). TV security system (if you have not turned off intentionally) will not do
RI (afterimage). Depend on the specific model, but in general are taking place. Suffice it to 3 hours with the static element and silhouette may appear on a black background. Coming off itself after a few tens of minutes, and on a normal picture by. If you look at a movie plasma – OI you will never see it. If a long time to play or watch TV channels, in which. For example. is the emblem in the corner – it is possible. Connect the monitor – the plasma is not for that
OLED
One of the new imaging technology in TVs.. OLEDs that somewhere between IPS and plasma. The image is formed by means of self-illuminating diodes that glow under the influence of an electric current. As in the plasma, each cell is independent of light source – the displays do not require backlighting. Developments in this field are engaged in LG and Samsung. Now it released a bit serial samples at a price much higher than the similar LCD and plasma TVs. But companies will cheapen the cost of production, to run in the technology. Within 3 years matrices significantly drop in price, if at the same time have excellent quality.
There are several characteristics that need to pay attention when choosing a TV. Such as: the type of lighting, contrast, black level, brightness, color accuracy. But before you choose something, we advise you to visit thematic forum, in order for you to have an idea about the technology on which modern TVs built, and already the basis of this made your choice.
