A study of highly efficient organic light emitting transistors that outperforms organic light emitting diodes

Organic light emitting transistors (OLETs), which are used in optoelectronic devices, have progressed in recent years. Electroluminescence is a characteristic of organic light emitting diodes (OLEDs), and OLETs integrate OFET's synchronising processes with the OLEDs. OLETs are ideal for creating the next generation of displays because of their distinctive look. OLETs, the upgraded form of OLEDs, are attracting attention these days because of its architecture, flexibility, light weight, and low cost. This review specifically looks at the process of developing high-efficiency OLETs considering different OLET structures and optimizations. In this paper, various properties, behavior characteristics, and performance parameters are taken into account. Besides this, we also present a comparison between OLEDs and OLETs. Additionally, OLET performance is examined in terms of drive current, mobility, ON-OFF current ratios, and external quantum efficiency for single and multilayer designs. It is the goal of this study to emphasise and build a better knowledge of the future design of OLETs by analysing the existing state of the art.

Automated summary

Organic light emitting transistors (OLETs) have made progress in the field of optoelectronic devices, integrating the characteristics of electroluminescence from organic light emitting diodes (OLEDs) with the processes of organic field-effect transistors (OFETs). OLETs, as an upgraded form of OLEDs, have gained attention due to their architecture, flexibility, light weight, and low cost. This review focuses on the development of high-efficiency OLETs, considering different OLET structures and optimizations, and also compares them to OLEDs.
