New OLED tech by researchers promises energy-efficient TV and smartphone screens, enhancing sustainability by reducing power consumption.
High-efficiency blue organic light-emitting diodes are a type of organic electronics that are already widely used in displays and cellphones and have the potential to be more efficient than rival technologies.
Now, a team of researchers at Northumbria, Cambridge, Imperial, and Loughborough universities have developed a novel approach to simplifying OLED architecture with high efficiency.An organic semiconductor layer is sandwiched between two electrodes in an OLED’s construction. The emissive layer, which glows when driven by electricity, is located in the middle of the stack. The molecules absorb electrical energy, which is subsequently released as light.
A crucial component of this investigation is the findings related to characteristics of organic semiconductors derived by Dr. Marc Etherington, Assistant Professor in Molecular Photophysics at the Department of Mathematics, Physics, and Electrical Engineering at Northumbria University. Researchers present a molecular design wherein ultra narrowband blue emitters are securely encapsulated through covalent bonding with insulating alkylene straps. “Organic light-emitting diodes with simple emissive layers consisting of pristine thermally activated delayed fluorescence hosts doped with encapsulated terminal emitters exhibit negligible external quantum efficiency drops compared with non-doped devices, enabling a maximum external quantum efficiency of 21.5 percent,” said the study.
