Abstract: The fabrication of a single-layer NIR OLED by a new luminescent material. Demonstrate vertically stacked device consisting of organic photovoltaic device (OPV) and organic light-emitting diode (OLED) inside a polymer dispersed liquid crystal (PDLC) cell. In such a device, OLED and PDLC acted as transmissive (T-) and reflective (R-) mode respectively, of a transflective display without the tradeoff of aperture ratio between R- and T- modes in a conventional transflective LC display. The characteristics of this diode is considered and investigated with different thicknesses. Electroluminescence is observed with the peak at 800 nm. Storage lifetime of OLED increased in the stacked device because LC material helped to prevent the water and oxygen attack. Driving voltage of PDLC increased due to the insertion of passivation layer upon the electrode which was used protect the OLED and OPV underneath.
