LED TV

In the world of modern technology, that day is a novelty. And half a century ago, no one could imagine that your favorite movie can be watched without leaving home, and most importantly - in high quality. What makes an ordinary image clear, and the picture brighter? What is an LED TV, what are its features and benefits? Should I buy this equipment at all and how to choose the right model in this case? In this article we will try to reveal all the most important aspects concerning the topic of LED TVs.

What is LED TV?

And yet, what is an ice TV?How to distinguish it from the usual? It would be reasonable to begin by deciphering the term itself. LED from English is interpreted as light-emitting diode, and in Russian the analogue of this term sounds much clearer - "LED".

Having studied the configuration of this device, we can say that LED TVs are the same LCD TVs. Then what is the difference? In order to find out, you should study the features of LCD monitors. The main component of this type of technology is a matrix with pixels. Pixels are luminous points.

Returning to the topic, the main feature is the light sources:

• In LCD monitors - it is a fluorescent lamp with a cold cathode.
• In LED TVs, the role of the backlight is performed by LEDs, which were discussed in the description.

We hope that this information will help you to distinguish these two practically identical types of TV.

How to choose LED TV?

So, now you already know what LED TV is. Now let's move on to the topic: how do you decide, choosing this miracle of technology? How to make an intelligent choice?

General rules

Follow these tips and you will succeed:

• When choosing a led TV, you should pay attention to the diagonal size. According to experts, it is worth to stop on the model, the diagonal of which in threefold size will be equal to the distance from the monitor to the viewing point. This will ensure you a pleasant viewing.
• An important role is played by the brand and manufacturer. Sometimes even the most advertised technique does not meet expectations. Therefore, before buying it would be nice to read reviews of people on the Internet who already own this device.

Important! If you look on the other hand, then the popular manufacturers will provide you with a long-term warranty, and in case of problems - will fix any problems or errors in operation. This is an important aspect when choosing a new TV.

• When choosing the resolution, it is advisable to stop at the biggest one - it's Full HD.With this resolution, the image will be clear, bright and accessible.
• Speaking about the quality of the image, it should be noted that before buying an LED TV, you should test the quality of the picture in the store, namely such items as: whether the brightness of this monitor's ice or the color palette is suitable for you.

Important! To distinguish the quality of flowers, pay attention to the skin color of people in the frame, their movements. If it is mixed with yellowness, and accordingly - the movements are not smooth and sloppy, then on such a technique one should not stop your choice.

White or composite LEDs

As we already know, the backlight of the monitor in the LED TV is carried out with the help of special LEDs. In order to realize this theory, white diodes are used in the manufacture of television sets, from which, as a result of the direction of light to the light filters, red, blue and green colors are obtained.

But since with the help of white LEDs the required spectrum of light could not be obtained, the manufacturers began to use composite LEDs( as they are called, "quantum dots").They work on this principle:

• in these LEDs, the blue and green colors are combined into one and "top" are covered with a red phosphor;
• is sometimes the other way around - red and blue serve to merge, and the green phosphor "covers" them.

In general, the main feature that distinguishes between white and composite LEDs is the principle of the backlighting of the display.

Quantum dots in LED monitors

Quantum dots are one of the innovations in the world of modern technology. During manufacturing, some diodes are replaced with so-called quantum dots. Often, instead of red and green LEDs.

Millions of these points serve as a kind of light filter, with which the necessary color is formed.

Important! This method of providing natural color reproduction is popular among manufacturers, since it is relatively inexpensive and inexpensive.

Features of LED TV

Televisions of this type have certain features that we will now consider. So:

• The case of LED monitors is thinner than that of a conventional TV.
• You can watch such TVs practically from different angles of inclination and foreshortening.
• The image has a high contrast color.
• Led TV - less energy-consuming kind of technology than its "colleagues."
• The color scheme is characterized by high brightness, color saturation and image clarity.

We hope that after studying this information about the features of LED screens, it will be much easier for you to decide on the appropriate model for a new device in your home.
