This article presents a review on various aspect of organic light emitting diodes (OLEDs), such as their working, various categorization, impact of fabrication methodologies (organic vapor phase deposition, vacuum thermal evaporation, inkjet printing etc.) that are low-cost and their applications in serval domains like medical, sensor, display, lighting etc. Three categorizations of OLED are discussed with respect to circuit, architecture and color of emission. Different layers of multi-layered structures such as injection layer, transport layer, block layers are also reviewed and their impacts are analyzed and compared. Moreover, an experimental fabrication technique for flexible substrate is reviewed that highlights low-cost fabrication method. In this technique, dynamic viscosity and contact angle are measured using rotational viscometer and contact angle meter, respectively. The result illustrates sheet resistance and effective opening ratio of 3.8 ohms per square and 82.5%, correspondingly. Additionally, various performance parameters like luminescence, external quantum efficiency, and current efficiency are compared. The paper also incorporates recent advancement in organic thin film transistors along with some OTFT driven OLED devices.

TOLEDs (transparent organic light-emitting diodes) have emerged as one of the most promising ways to implement next-generation display form factors. Transparent OLEDs can provide new added value to HMDs (head mounted displays), automobiles, smart windows, mobile devices, TVs, etc. through their transparency, which allows objects to be seen from the other side. However, previous approaches using metal thin films have faced limitations in attempting to achieve high transmittance. In this study, TOLEDs were designed using a new cathode structure consisting of an interlayer and an emission pattern layer, and these layers connect the light-emitting part and the nonemitting part by themselves without requiring the use of another interconnection layer. This structure, which was intended to improve transmittance, was implemented by applying an in situ evaporation process that adds only one shadow mask without the need to use any difficult methods. Through this process, the optimal condition was found when the light-emitting part was deposited in a mesh pattern with a length of 120 μm and a width of 80 μm, in which case the transmittance of the TOLED improved by up to 83% while maintaining electro-optical performance. It was also confirmed that this new structure can be applied to flexible devices.
