OLED screen technology is already on everyone's lips: ultra-thin, flexible and even transparent screens. But what do we know about this technology? What are the advantages? Will it be within our reach in the near future?
The English abbreviation OLED refers to the acronym for Organic Light Emitting Diode, a technology that uses an electroluminescent layer formed by an organic thin film to react when a current is applied. Emitting light by itself.
This concept in itself has more advantages than its predecessors, because the previous ones are based on LCD technology that must be backlit by using plasma or LEDs. On the other hand, OLEDs do not require auxiliary lighting systems, which allows them to win in terms of size reduction, color contrast and energy efficiency.
There are still limitations in the use of OLED screens, such as high production costs, difficulty in recycling, or the complexity of the technology to obtain large sizes; so we will not see large exterior walls covered with organic LEDs.
The latest advances in this evolving technology show that this thin layer of organic LEDs can be deposited onto a flexible surface, allowing you to reproduce dubbed images or use them as transparent media. The day has come when we have "unfolded" our smartphone to get a tablet, and be able to watch our favorite videos in the most comfortable way.
For now, the use of OLED will have to wait a while to be perfected, but without a doubt we will wait for the birth of a technological revolution.
