--Organic light-emitting diodes (OLEDs) are among the most successful
organic electronic devices so far. They currently dominate the mobile
display market and are expanding into a broad range of lighting, automotive
and wearable device applications. Here we introduce a new class of organic
light-emitting device that exhibits bistability owing to positive photonic
feedback between an organic photodiode and a tandem OLED integrated
in the same layer stack. These unusual devices display giant hysteresis in
both their current and light emission, and respond sensitively to low-level
external illumination, enabling optoelectronic upconversion with 100-fold
photon-to-photon gain. Given their compatibility with existing OLED
materials and manufacturing lines, these devices could find near-term
use in new types of display and upconversion imaging applications, as
well as offer a new platform for neuromorphic optoelectronics and image
recognition.--
