The initials OLED comes from the English expression organic light-emitting diode; that is to say, "Organic light emitting diode" or "Organic light emitting diode" . This is the name of diode made with organic materials able to react to an electrical stimulus.
OLED technology, therefore, does not use semiconductors or metals. His organic film is electroluminescent : upon receiving electricity, generates and emits light .
The structure of an OLED has a conduction layer and an emission layer, both made of polymers or molecules that can conduct electricity. Sony , LG , Manzana and Samsung are some of the Business who have appealed to this resource on different devices.
OLEDs have produced monitors, televisions, cell phone screens (mobile) and advertising posters, for example. Among the advantages attributed to it compared to the screens of led or LCD , its flexibility and its thinness are usually mentioned.
OLEDs, on the other hand, consume less electricity (since they do not require a backlight) and allow a wide range of contrast and colors. At the other extreme, its useful life is limited and easily damaged.
If you specifically compare an OLED with a LED, the OLED offers greater efficiency, speed and brightness. The led, meanwhile, is cheaper and has a durability up to five times higher than the OLED.
It is important to keep in mind that, while an LED TV needs LEDs for the backlight of the screen, on an OLED TV they are the own organic diodes those that form the screen and light it up.
