QLEDs use quantum dots (nanoscale semiconductor particles) for the emission of light. Thanks to their outstanding electroluminescence, they have attracted considerable attention as a candidate for the next generation of display technologies. QLED displays do not require any bulky components such as backlight units, potentially allowing them to be manufactured with ultrathin form factors.
A research team of experts from Seoul National University and the Institute for Basic Science presented a prototype QLED in 2015 that had a thickness of just 3μm. Thanks to its thinness, it had outstanding mechanical flexibility, which allowed it to be applied in wearable devices such as electronic tattoos.
The team has now presented the next stage of this technology - a foldable variant of the ultrathin QLED inspired by origami. Considering the rising popularity of foldable smartphones, the evolution of foldable display technology is becoming more relevant. It is expected...
