Types of TV screens
Lamp TVs have sunk into summer. Their era has come to an end. The old round CRTs were replaced by flat screens, distinguished by their beautiful views. From now on, manufacturers have been able to create such monitors that are impressive in size. Of course, all of them are presented on the market within reason, so that it is convenient and comfortable to use them.
Buyers, in turn, are happy to learn information about mega-inches and do not spare money to purchase new large TVs in the conditions of home appliances stores. But do not forget that the bigger the screen does not mean that in practice it will be better. Before you understand how to choose the right TV diagonal, it is recommended to learn about the types of devices on the market.
OLED TVs
OLED screens are based on a matrix equipped with organic diodes. During the transmission of an electrical impulse, they glow. On the surface of the crystal there is a phosphor, which is responsible for the color of the light beam in green, blue or red. This method makes it possible to produce screens of different shapes. There are flexible panels on the market, but this solution is rarely used in the case of TVs.
pros
- the quality is high;
- the brightness of the image reaches 100,000 cd / m2;
- viewing angles are not limited;
- contrast and color reproduction are excellent;
- energy consumption is low;
- no flickering, the minimum response time is 1000 fractions of a second;
- the picture is realistic;
- there is a large selection of sizes, although large OLED formats are rarely successful, as experience shows.
Minuses
- the blue phosphor burns out very quickly;
- the price is very high;
- not every manufacturer was able to master the Oled technology.
LCD TVs
These devices work by taking into account the sifting of the luminous flux. This process is called polarization. In LED models, it is formed by diodes, but in LCD special fluorescent lamps are responsible for the process. In general, the principle of operation does not differ from each other.
There are liquid crystals on the glass of the monitor. They also contribute to the delay of light waves and their transmission. As a result, a part of the picture is formed on the screen.It is important to note that the properties of the electromagnetic field that acts on the LCD coating, as well as the sifting itself, occurs somewhat differently. The picture on the TV will change. This technology makes it possible to create wide and thin screens. Of course, it has both pros and cons. It is also important to know about them in order to understand how to choose the right TV diagonal.
pros
- electricity is consumed at a low level;
- lack of image flicker, which tires the human eye;
- the brightness is quite sufficient for the glow. It meets indicators in the region of 170-250 Cd / m2;
- picture transmission is clear, there is no distortion;
- the choice of diagonals is very large;
- affordable cost in the market;
- service life is long.
Minuses
- lack of volume and depth of the picture;
- the response time of the matrix is quite long;
- the angles are small, the view corresponds to the limits of 50-125 degrees;
- the resolution is fixed.
Plasma TVs
In appearance, this option has a lot in common with LCD monitors. But if you look at it, it is based on a completely different technology for image image. Here, pixels appear in the light, which are created by cells with gas, which is included in them. In case of voltage supply, ionization of the internal gas medium is observed, which is accompanied by a glow. Those. for those who are familiar, the same process is carried out in lamps of the fluorescent principle of operation.
pros
- the viewing angle is large, the picture quality is not lost;
- the image is juicy, realistic enough, the contrast is high;
- the blinking frequency is approximately 600 Hz. The human eye will not notice such an indicator;
- the response is fast. Screen movements will not be blurry.
Minuses
- plasma has a large format, such TVs with small diagonals are not available on the market;
- the cost is high, and the energy consumption is at the same level, and therefore this product segment is gradually leaving the market;
- short service time when compared with LCD models;
- the pixels are large.
Features of the choice of the diagonal
Parameters: Distance to screen
This is a really important criterion. It is worth knowing which diagonal of the TV to choose with the distance to it from the sofa. Agree that if the TV is small, it is very difficult to watch what is happening on the screen from a distance of 10 meters. And it is inconvenient to turn your head while standing close to the plasma, because it can occupy half of the wall. For this reason, it is important to understand how far from the TV area the sofa is located in your home.
Experts often recommend that the distance from the TV to the sofa fit in 3-4 lengths of the diagonal of the device itself. But there are other tips, and we'll talk about them a little below:
- a diagonal of 17 inches will be a good solution if the distance is not more than 1-1.5 m;
- 25 ″ - 2m;
- 32 ″ - 2.5m;
- 37 ″ - 2.7m;
- 40 ″ - 3m;
- 50 ″ - 4m;
- 63 ″ - 5m;
- 80 ″ - 6m.
Resolution rate
When choosing which diagonal TV to choose in a room, it is important to decide with such a parameter as resolution. It can be Ultra HD (4K), HD (1280x720) and Full HD.
The most common format today is considered to be HD. The distance to the screen and the diagonal are 1: 2.3. If the distance is 1 m, then choose a 17 "TV, but at 2 m - 34". Those. for each meter, add another 17 ″ until the desired value is reached.
Full HD resolution is designed for 1920 x 1080 pixels. The distance to the screen and the dependence of the diagonal distance will be as follows: 1 m - 25 inches, 2 m - 50 inches. Those. follow the addition of 25 inches per meter. A factor of 1.56 is taken into account.
But the modern Ultra HD (4K) format provides the best picture quality. The resolution is 3840x2160 pixels. Those. you can afford to buy a modern panel, the diagonal of which will be impressive. With a distance of 1 m - 39 inches, with a distance of 2 m - 78 inches.
It gives even better picture quality with a resolution of 3840x2160 pixels, which means that you can afford a cool panel with the largest diagonal:
The relationship of the diagonal and resolution of the TV screen
Choosing the right screen and display size isn't easy. It is important to consider the resolution features of the device, as well as take into consideration the appropriate formats. The thing is that the final picture, the comfort of viewing it on the screen, largely depends on the resolution.
The higher the number of pixels, the better the image quality. If the picture on the screen is made on the basis of a large number of dots, then TV viewing can be even at the minimum distance. For example, with a diagonal of 32 inches and 625 pixels, it is more convenient to watch TV from 2.5 meters. But if the pixels are 720, and the diagonal is 32 inches, then the distance will be 1.9 meters optimal.
Not every buyer today knows what resolution is and how the correct distance from the screen to the sofa with the viewer is calculated. For this reason, this information was included in our article. We hope you find it really useful.
Features of the room
It is important to achieve an optimal result not only in terms of the distance between the TV and the viewer, but also to make it fit harmoniously into the overall interior. It is not necessary to allow it to get lost against the general background, and it is ugly if the device obstructs half a wall in a small room.
In a store environment, it is really difficult to understand what the dimensions of the panel are. Unless there is an opportunity to compare it with screens from other brands. For this reason, it is better to clarify the indicators of the height and width of the TV, and at home, transfer the dimensions to the wall and estimate how successful the model will be.
If the room is small, then give preference to a TV with a 20-inch screen. With an area of up to 18 sq. m, choose a TV that is not more than 37 inches diagonally. Above 40 "options are optimal for spacious rooms. It could be 20 sq. m and more.
If there is a choice of a TV for the kitchen, then it is better to stop at HD resolution and 17-20 inches diagonally. Such a device will be appropriate for installation above a table or in the existing free opening between cabinets.
In the living room or bedroom, which are more than 20 sq. m, it is better to install a TV with FHD resolution and 40-42 inches of screen. Panel size can be increased up to 75 inches. As a rule, in such rooms the distance to the screen from the sofa will not be more than 3 meters.
But if you have a large enough budget at your disposal, and even sq. meters allow, purchase Ultra HD resolution. Large-format TV with high image quality can occupy the entire wall.
Price question: how much do TVs with different diagonal settings cost?
This is really an equally important nuance that you should rely on when buying. Today, not every our fellow countryman is able to afford to buy a large TV with 4K technology. Of course, such a purchase may not always be appropriate, as the information in the article makes clear.
As for the analysis of prices on the market, if you need a small TV with a diagonal of no more than 20 inches, then you can buy it from 5800 - 70,000 rubles.
But for a size of 30-40 inches, you will have to spend in the region of 10,000 - 227,000 rubles. 50 inches is a little more expensive - 50,000 - 250,000 rubles.
If you decide to buy a large screen with a diagonal of 60-70 inches, then count on 156,000 rubles. For such models, the highest price varies around 1.6 million rubles.
But this is not the ceiling yet. For the panel, which will have a mega-diagonal of 100 inches, you need to pay about 4.5 million rubles. But such a purchase will certainly not fit - neither in price nor in size for most of our compatriots.
Summing up
In the modern market, there are a lot of LCD TVs with different diagonals. Experience shows that they are all fundamentally different. The parameters you should rely on at the time of purchase vary. Please note that, not knowing how to choose the correct TV diagonal for the room, you run the risk of making an unreasonably large waste, which will not bring the desired result in the future.The greater the distance from the TV to the viewer, the higher the monitor diagonal should be.
What choice to make is up to you. But keep in mind that in any case, it is very important to take into account the parameters of the room itself. Don't forget to consider your personal preferences as well. You should like the TV, fit well into the interior. Anyone who wants to buy an acceptable option that suits the quality of the picture and cost, you need to study the range of goods in more detail. The choice is very difficult, there are many models, and therefore it is not surprising that you can get confused.
Approach the purchase as responsibly as possible, and then in the future the model will certainly not disappoint you, and leisure in front of the TV will bring extremely positive emotions.
