If in the evenings you want to enjoy watching your favorite movies, TV shows and TV shows, then you just need to purchase a good LED-TV. Currently, manufacturers of equipment offer a huge number of such devices at different prices. Find out what an LED TV is. These TV panels have a huge number of advantages and will please their owners with high-quality, vivid images.

What are LED TVs

LED-TV is a device that is a TV receiver with a liquid crystal screen. The matrix is ​​equipped with a special backlight from a set of LEDs. Decoding of the abbreviation LED is “Light Emitting Diode”. From a technical point of view, such devices would be more correct to call liquid crystal with LED backlight. However, Samsung was the first to launch such a device on the market under the name “LED TV”. Other manufacturers adopted it, so it became common.

LED backlight

Now they produce different types of such devices. They differ in the type of LEDs used, the arrangement in relation to the screen. By the color of the lamps:

1. One-color (white White LED). A budget option. Deprived of the minuses of luminescent backlight, creates an image with a similar color gamut, but not as contrasting.
2. Multi-colored (base color triad RGB LED). The color palette is expanded due to the brightness control of the LEDs. The number of halftones increased. To support this technology, you need a powerful graphics processor. The model will cost more and consume more power..
3. Mixed. Blue backlight LEDs and a special film with green and red quantum dots. This technology reduces the power consumption of the device..

What is the LED backlight on the TV, we found out. In addition to the color of the lamps, it differs by their location. There are two options:

1. Directly behind the LCD matrix. Direct backlight type Full or Direct LED. These models are cheaper than Edge, but not so thin. With a high level of contrast. They have white and multi-colored LEDs.
2. Along the perimeter of the LCD matrix. End type of illumination Edge LED. LEDs are located on one (bottom), two (side) or four sides of the screen. Due to this, manufacturers produce models with a thickness of less than 1 cm in these white LED devices. Budget models made using this technology have a drawback. They are visible highlights along the edges of the screen. In addition, they have a low level of contrast.

Characteristics

The market offers a huge variety of models from different manufacturers. They differ in price depending on the parameters they possess. To make it easier to choose a model based on your budget when buying, learn to understand at least the key features that an LED TV has:

1. Resolution. There are several options: Full HD, HD Ready, Ultra HD. The latter is considered the best.
2. Smart function. Thanks to this option, the Internet is accessed directly from the device. There are models with a built-in router and without.
3. Sweep frequency. Shows how many times per unit of time the image is updated..
4. 3D image function. If you plan to watch movies in this format, then choose from two options for display technology: active and passive. Compare both options in the store and determine which eyes are more comfortable..
5. Matte or glossy screen. The first one has a not so wide viewing angle, and the second glare.

Benefits

An LED TV is nothing more than an LCD screen, but an advanced one. In liquid crystal, CCFL cold cathode fluorescent tubes were used as a light source. They were replaced by LED backlight. This eliminated the liquid crystal devices from characteristic shortcomings. Thanks to LED technology, TVs have become thinner (especially Edge models). They are environmentally friendly and energy efficient, do not contain mercury, do not require specialized disposal. Benefits:

• more contrast image in comparison with other technologies;
• maximum viewing angles;
• rich and natural colors;
• the consumption of a relatively small amount of energy;
• display high definition signals;

How to choose an LED TV

Buying home appliances is a very crucial moment that you need to approach with all seriousness. It is important to contact stores with a good reputation that guarantee the quality of their goods. You can either buy a LED-TV, or order in the online store with delivery from Moscow or St. Petersburg to your home by mail. It is profitable to buy equipment before the holidays, during such periods in stores often arrange sales and promotions, offer excellent discounts. Tips for choosing an LED TV:

1. Screen diagonal. This is one of the most important indicators. Many people think that the larger the screen, the better. The optimal size should be calculated as follows: divide the estimated distance from the viewing point to the LED TV by three. The diagonal should be equal to the number you got.
2. Screen resolution. Best for today, but also the most expensive will be an Ultra HD LED TV.
3. Image quality. This parameter must be chosen, focusing on personal preferences. In stores, as a rule, there are a lot of working TVs broadcasting the same file. Compare which image you like best.
4. Screen coverage. Glossy contrast and brighter. However, it is not suitable for a room in which there is a lot of sun, it will glare. Matte makes the image less clear, but does not shine at all..
5. Format. The most popular at the present time is 16: 9. Suitable for watching both digital and satellite television. The second 4: 3 format option is suitable for cable channels.
6. Manufacturer. Buy only products of companies that have long been working in the market and have proven themselves. Pay attention to online reviews.
7. Settings The more options you can adjust, the better. On some budget models it is impossible to change even the brightness of the image.
8. Additional functions. Modern LED TVs are equipped with many options that are not critical: voice control, wi-fi, built-in router. Evaluate the budget and decide which of the “bells and whistles” you need.
9. A set of functional connectors. It is better to purchase a TV that has HDMI, USB ports for connecting other devices. Check if the connectors are conveniently located, whether access to them will be difficult.
