The development of electronic applications can take on many new forms to include foldable and wearable displays to monitor human health and act as medical robots.
Such devices rely on organic-light emitting diodes (OLEDs) for optimization. However, it is still challenging to develop semiconducting materials with high mechanical flexibility due to their restricted use in conventional electronic formats.
In a new report on Science Advances, Minwoo Choi and a team of scientists in Electronic Engineering and Materials Science in the Republic of Korea, developed a wearable, full-color OLED display using a two-dimensional (2-D) material-based backplane transistor.
They engineered an 18-by-18 thin-film transistor array on a thin molybdenum disulfide (MoS2) film and transferred it to an aluminum oxide (Al2O3)/polyethylene terephthalate (PET) surface.
Choi et al. then dep
