Researchers at the Korea Institute of Basic Science (IBS) and Seoul NaTIonal University have developed an ultra-thin wearable quantum dot light-emitting diode (QLED) that sticks to the skin of a human body like a sticker. This "electronic tattoo" sticker is based on existing QLED technology. Colloidal quantum dots (QLEDs) continue to receive close attention from next-generation display developers because they have novel properties such as color tunability, photo/air stability, and can be printed on a variety of On different substrates. This QLED assembly is as light and thin as paper and can be applied to the skin like a sticker. QLED can stick to the skin like an electronic tattoo sticker The research team has now developed high-performance red, green, and blue QLED arrays with a resolution of approximately 2,500 pixels per inch. This resolution level is said to be better than other LED components and displays on the market today, even better than the latest smart phones. This technology can also be extended to a larger area. This QLED assembly is suitable for use in a deformable state so that it can be fabricated on unconventional curved substrates, including the surfaces of various objects. Further mechanical deformation, such as stretching or creping, is used to make QLEDs visible on people's skin. This new research breakthrough opens the possibility of opening other new applications for wearable electronics that integrate high-resolution full-color displays. QLED components leverage existing technology to extend IoT applications.
