What is OLED?

What Does OLED Mean

The acronym OLED comes from the English expression organic light-emitting diode ; ie "organic light emitting diode " or "organic light emitting diode" . This is the name given to the diode made of organic materials capable of reacting to an electrical stimulus.

OLED technology, therefore, does not use semiconductors or metals. Its organic film is electroluminescent : when it receives electricity, it 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 , Apple and Samsung are some of the companies that have used this resource in different devices.

With OLEDs, monitors, televisions, cell phone screens (mobile) and billboards have been produced, for example. Among the advantages attributed to it over LED or LCD screens , its flexibility and thinness are often 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.
In addition to the aforementioned advantages, we cannot ignore that OLED technology brings with it another significant series of benefits, among which the following must be highlighted:

-In the future it is expected that the manufacture of systems that have it will be much less expensive than others with similar characteristics.

-In the same way, we cannot ignore either that, without a doubt, televisions and other devices that have it offer higher image quality.

-Also, it must be emphasized that the response time of a pixel in what is an OLED-class panel is much higher. Specifically, it is 0.01 ms.

-In this list of benefits of OLED technology, we must also include the fact that its panels have less thickness than others that have other technology.
Among their disadvantages we can highlight, for their part, some such as the following:

-They have a much shorter useful life than that of other systems that may exist. Thus, while a TFT type panel has a life of between 25,000 to 40,000 hours, an OLED type has about 14,000 hours.

-It must also be established that OLED panels are more easily damaged and that they can break completely if they come into contact with water.

-In addition, it is necessary to know that the panels we are dealing with degrade at a higher speed what the blue color is than other panels with different technology.
If an OLED is specifically compared to an LED, the OLED offers greater efficiency, speed and brightness. The LED, for its part, is cheaper and has a durability up to five times higher than the OLED.

It is important to bear in mind that, while a LED TV needs LEDs for the backlighting of the screen, in an OLED TV it is the organic diodes themselves that form the screen and illuminate it.
