The modern market offers many new imported products in the field of household appliances. Today, going into the store, we can see dozens of TVs, including those produced using the most modern technologies. Quite expensive models are LED TVs. And many are interested: LED TVs - what is it, and is it worth paying big money for them?
The abbreviation LED stands for "light emitting diode". These elements, arranged in a matrix, form the basis of the TV screen and give devices in this class a difference from CCFL class liquid crystal screens (using fluorescent lamps), and also distinguish them from cold cathode screens.
What are LED TVs in terms of picture quality on screen? The use of LEDs gives TVs in this class the ability to demonstrate the backlighting of each element of the screen, unlike cold cathode lamps, which illuminatescreen completely. This approach allows you to get a fundamentally new kind of contrast, which makes the image as clear as possible. In addition, LED TVs, whose technology allows the use of both single-color and tri-color diodes, provide a wider color gamut that is not available with other TV models.
Nowadays, in the production of various household appliances, elements that pollute the environment are often used, which does not allow us to consider the future safe. Therefore, some sane people are thinking about what LED TVs are in terms of environmental safety, and how they can be disposed of in the future. And they can be happy: LED-systems do not contain mercury components; unlike incandescent lamps, they consume 35-40% less energy. In addition, damage to a small part of the TV screen does not lead to a complete lack of image. TV can be watched further.
When choosing a TV in a store, some people pay attention to additional abbreviations in the name - Direct or Edge. And many people want to know what Direct class LED TVs are. The word Direct in this case means that the LEDs are evenly spaced on the screen, and the word Edge means that the diode matrix is located at the edges of the screen and is complemented by a diffusing panel. Direct TVs are considered to be better and more expensive, while Edge models are popular due to their minimal thickness (this indicatormaybe around 4 cm).
The latest examples of LED technology have rich functionality. Internet access, the ability to download and view files (music, clips, photos), download from your phone or via USB, image converter to 3D (from 2D), Skype access, watching 3D movies without glasses - that's what LED TVs are today. You just need to choose the right screen size - very large ones are not suitable for all rooms, because they give graininess in the image, which makes it difficult to enjoy the latest technology. All models of LED TVs have an attractive design, which allows them to fit perfectly into any interior and even become its decoration.
