OLED TVs - the technology of the future

Today, huge television "boxes" with cathode-ray tubes no longer appear in home appliances stores. They were supplanted by flat displays, which at first glance seem to be exactly the same. However, the technologies used in the manufacture of matrices of their screens can be completely different, which affects not only the image quality, but also the vision of the owners of the TV.One of the latest developments are OLED-displays. So what is it - OLED-TV, and what it may interest the buyer?

The essence of technology

The principle of operation of technology OLED

OLED is an organic LED consisting of semiconductor materials( most often doped indium oxide in combination with calcium and other metals) and polymers of organic nature .

When a current is applied to such a diode, a fast recombination of electrons and holes occurs, during which electrons lose energy and emit light of the visible spectrum. Each pixel includes three OLEDs: red, green, and blue.

Advantages of TVs with OLED-matrices

OLED technology wins from LED and LCD in terms of mass parameters

Among the advantages of displays based on OLED technology, the most obvious is the high brightness and contrast of the image. The contrast reaches a value of 1: 1 000 000, unprecedented in the digital world. In most cases, the power consumption of OLED-TVs is much lower than that of their liquid crystal counterparts, due to "economical" electronics. The consumed electrical power is directly proportional to the area and brightness of the screen.

An important advantage, especially relevant in connection with the rapid development of multimedia technologies, is the ability to create displays on organic diodes with very high resolution( up to 8K with relatively compact dimensions), as well as curved screens.

Which models to pay attention to?

Organic Diode Production is a time consuming and expensive process, and therefore there is no in the budget price segment of OLED TVs. One of the best "middle class" devices will be a 55-inch LG 55EG9A7V TV with Full HD resolution. Its price is about 100 thousand rubles.

LG 55EG9A7V - the most affordable option from OLED

LG LG OLED55C6V TV costs twice as much, because with the same diagonal, it has a concave 4K standard display.

LG OLED55C6V is an order of magnitude more expensive because of the concave screen

If you are ready to pay a million for a TV, look at the Sony KD-65A1.It has a smart module running the Android OS, has a diagonal of 65 inches, and its resolution is 3840 × 2160 pixels.

OLED - is the technology of the future, which many still can not afford. It is hoped that the development process of organic semiconductors will go quickly and intensively.
