South Korea develops world's first fiber-based white OLED or could be used in vehicle design

Core Tip: According to foreign media reports, researchers at the Korea Institute of Science and Technology (KAIST) claimed to have developed the world's first fiber-based white organic light-emitting diodes (WOLEDs), paving the way for more powerful wearable technology. flat road.
According to foreign media reports, researchers at the Korea Institute of Science and Technology (KAIST) claim to have developed the world's first fiber-based white organic light-emitting diodes (WOLEDs), paving the way for more powerful wearable technology.
The research team proposes a single dip-coated white emissive layer suitable for fiber structures to design fiber-based WOLEDs. According to KAIST, during the design process, the researchers found a way to implement WOLEDs on fiber strings by simulating and optimizing the white spectrum. Related research papers have been published in the journal Advanced Science.

Putting WOLEDs on a string of optical fibers has been difficult until this research. Because WOLEDs consist of tandem structures, they are two to three times larger than the single-stack structures of tri-color (red, yellow, and blue) OLEDs.

According to KAIST, the fiber-based WOLED shows strong lighting performance and reliable color index, and also has stable durability in terms of sweat resistance, pressure resistance and biocompatibility.

Hwang Yong-ha, lead author of the study, said: "As a fundamental technology is missing in the field of developing electronic fiber displays, we hope that WOLEDs will enable high-quality electronic fiber displays."

The researchers point out that WOLEDs are necessary for full-color displays. The researchers say the fiber-based WOLEDs could be used in various fields such as fashion, functional clothing and vehicle design in the future. KAIST also added that there is a global effort to improve electronic fiber display technology to help redefine the field of wearable technology.
