We fabricated a novel device assembled by coupling a transparent organic light-emitting diode (TOLED) and a glare-tunable transparent electrochemical device. This device could be operated in six different states, namely, (1) transparent, (2) mirror, (3) black, (4) dual emission, (5) single-side emission with mirror, and (6) single-side emission with black. Switching between each of these states could be tuned by varying/ selecting the applied DC bias voltage. The device showed 63.8% transmittance in the transparent state, and 42.1% reflectance in the mirror state at 700 nm. Transmittance in both the mirror and black states was less than 0.1% in the visible range.

Inverted transparent organic light-emitting diodes (i-TOLEDs) were fabricated using thermal evaporation and spray methods. Only oxide compounds were used for the electron injection layer (EIL) of the diodes, and no alkali metals were included. Furthermore, these i-TOLEDs were fabricated with a nanoscale metal/dielectric multilayered transparent conductive film, which served as the anode.
