The modern market offers many new imported products in the field of household appliances. Today, going to the store, we can see dozens of televisions, including those released using the most modern technologies. Quite expensive models are LED class televisions. And many are interested in: LED TVs - what is it, and is it worth it to pay a lot of money?
The abbreviation LED means “light emitting diode”, which translates as “LED”. These elements, arranged in a matrix, form the basis of the TV screen and give devices of this class a difference from liquid crystal screens of the CCFL class ( fluorescent lamps are used), and also distinguish them from screens with cold cathodes.
What are LED TVs in terms of screen image quality? The use of LEDs gives TVs of this class the opportunity to demonstrate the illumination of each element of the screen, in contrast to lamps that include a cold cathode, which illuminate the screen completely. This approach allows you to get a fundamentally new type of contrast, which makes the image as clear as possible. In addition, LED TVs, the technology of which allows the use of both single-color and tri-color diodes, give a wider color gamut, inaccessible to other TV models.
Nowadays, the production of various household appliances often uses elements that pollute the environment, which does not allow us to consider the future safe. Therefore, some sane people think about what LED TVs are in terms of environmental safety, and how they can be disposed of in the future. And they can be pleased: 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 entail a complete lack of image. You can watch TV further.
When choosing a TV in the store, some pay attention to additional abbreviations in the name - Direct or Edge. And many want to know
what Direct
- class
LED TVs are. The word Direct in this case means that the LEDs are evenly distributed on the screen, and the word Edge means that the diode array is located at the edges of the screen and is supplemented by a diffusing panel. It is believed that Direct class televisions show better and cost more, and Edge models are popular due to their minimal thickness (this figure can be 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 a phone or via a USB connector, an image converter in 3D (from 2D), access to Skype, watch 3D movies without glasses - these are LED TVs Today. You just need to choose the right screen size - not all rooms are very large, because they give granularity in the image, which makes it difficult to enjoy the last word of technology. All models of LED TVs have an attractive design, which allows them to fit perfectly into any interior and even become its decoration.
