Mexico. Using a molecule that can produce the colors to denote the chromatic range in OLED diodes, researchers from the Universidad Veracruzana seek to optimize OLED technology for flexible screens and lighting, achieving significant energy savings.
This molecule, developed by them, makes a significant difference with the way OLED diodes emit coloration today. Today, to generate luminescence, diodes require the excitation of electrons from various organic molecules to produce the colors blue, green, and red.
The development of the Faculty of Bioanalysis of the Mexican university, which was directed by Jorge Domínguez, is focused on not having to use three molecules separately to generate colors, but that a molecule generates RGB colors. This is achieved because the new system does not require chemically altering the molecule for color change.
The researchers pointed out that some functions of these new organic diodes would be focused on flexible screens, because they would have a longer service life, in addition to being a much greener product than the conventional screens that are found today in the market.
Another segment that would benefit is that of lighting, since it will be possible to further reduce the energy used to generate incandescence. That is, with lower voltage they can have greater luminosity.
