Low-damage deposition of transparent conductive oxides as top contacts for transparent organic light emitting diodes

Organic light emitting diodes, or OLEDs have become a common technology in everyday displays such as mobile phones, laptops, and televisions. These types of devices rely on an OLED structure that uses bottom-emission, meaning that the top of the device consists of a non-transparent backplane, and the light and colours generated in the device are emitted through the transparent, bottom side of the device. In order to incorporate OLED technology into new and exciting applications such as heads up displays, smart windows, or augmented reality, the device must be fabricated so that it is completely transparent and capable of both bottom emission and top emission. A significant challenge with a transparent OLED (TOLED) is that the transparent electrode which must be deposited directly on top of the light-generating organic layers can cause damage to the device and limit performance.
