Korean researchers develop transparent and foldable perovskite-based LEDs

Researchers from Korea's Ulsan National Institute of Science and Technology developed a new perovskite-based LED (PeLEDs) which are flexible enough to fold and are also transparent. It seems as if these LEDs are similar to OLED devices and provide area-lighting and not point-lighting like inorganic LED chips.

Perovskite-based LEDs have been demonstrated before, but this is the first time a transparent and flexible one has been developed, according to the researchers. Perovskite LEDs feature high electron mobility, good color purity, and easy color control.
