The acronym OLED comes from the English expression organic light-emitting diode ; that is, “organic light-emitting diode” or “organic light-emitting diode” . This is the name given to a 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 : upon receiving electricity, it generates and emits light .
The structure of an OLED features 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 on different devices.
OLEDs have been used to produce monitors, televisions, cell phone (mobile) screens and advertising billboards, for example. Among the advantages attributed to it over LED or LCD screens, its flexibility and thinness are usually mentioned.
OLEDs, on the other hand, consume less electricity (since they do not require backlighting) 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 manufacturing of systems that have it will be much less expensive than others with similar characteristics.
-In the same way, we cannot ignore that, without a doubt, televisions and other devices that have it offer higher image quality.
-Likewise, 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 are less thick than others that have other technology.
Among its disadvantages we can highlight some such as the following:
-They have a much shorter useful life than 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 panel has about 14,000 hours.
-It must also be established that OLED panels are damaged more easily and can break completely if they come into contact with water.
-In addition, it is necessary to know that the panels in question degrade the color blue at a faster rate than other panels with different technology.
If you specifically compare an OLED with an LED, the OLED offers greater efficiency, speed and brightness. LED, for its part, is cheaper and has a durability up to five times greater than OLED.
It is important to keep in mind that, while an LED television needs LEDs to backlight the screen, in an OLED television it is the organic diodes themselves that form the screen and illuminate it.
