Scientists create stretchable OLED display to increase size

Researchers at the University of California, Los Angeles (UCLA), new screen oled can be stretched more than twice its length while maintaining light output and a sharp image and can be used in wearable electronic devices.

Scientists have built several prototypes using computer guesses to develop new flexible electroluminescent polymers. The resulting materials were flexible, stretchable, shiny, durable and energy efficient.

A key feature in the design was the use of “thermally activated delayed fluorescence”, which allowed the materials to convert electrical energy into light quite efficiently. These third-generation mechanisms for organic emitters can provide materials with performance comparable to commercial OLED technologies.

Organic light-emitting diodes (OLEDs) are thin, flexible sheets of small organic molecules that emit light in response to an electric current. They are used in TV screens, computer screens, smartphones and handheld game consoles.

You OLEDs are one of the most advanced electroluminescent technologies. With their low voltage, high efficiency and brightness, and low price, they are perfect for integration into wearable and implantable devices. However, they do need adjustments to improve their softness and elasticity.

Research published in the journal Natureshows that new elastic oled It was developed using computer predictions and testing multiple prototypes to arrive at a winner with thermally activated delayed fluorescence (TADF).

The team plans to develop new screen versionsimproves performance and efficiency by integrating additional colors into fluorescent. The aim is to achieve the same level of performance as existing commercial technologies. This new elastic OLED is a class of material that could drive its development. Really flexible displays.
