First of all, it's important to remember how an OLED works. A single-layer OLED, the simplest device, consists of a layer of a small organic molecule or polymer deposited between two electrodes . EL is produced by injecting holes (at the anode) and electrons (at the cathode) into the organic layer, transporting these charges through the material, allowing them to recombine into an electron-hole pair known as an "exciton", and then relaxing these excitons to emit light. The color emitted by OLEDs is directly linked to the nature of the organic layer, and...
