Nanowerk  March 23, 2022 A team of researchers in the US (Stanford University, Berkeley National Laboratory, Southern Mississippi University) has developed a material design strategy and fabrication processes to achieve stretchable all-polymer-based light-emitting diodes with high brightness and stretchability (about 100 per cent strain). The final display contains seven layers. Two outer layers are two substrates that encapsulate the device. There are two electrode layers, each followed by charge transporting layers and the light-emitting layer sits sandwiched in the center. When electricity runs through the display, one electrode injects positive charges into the light-emitting layer while the other injects negatively […]
