Researchers from Yonsei University managed to use a graphene-like 2D material called Molybdenum Disulfide (MoS2) to create a transistor that can drive flexible OLED displays.
The researcher created a 6x6 OLED pixel array on a 7 mm plastic substrate that is so bendable (1 mm radius) it can be used as a skin sticker as can be seen in the video above.
The researchers say that up until now it was impossible to use MoS2 as a transistor as the resistance between the material and the source and drain electrodes are too high. The new design, builds the transistor on AiO3 layers, unlike the usually used SiO2. This boosts the charge carrier mobility of the MoS2 transistors.
