Advancements in the applications of organic light emitting diode

Numerous technological developments leading to more flexible devices and affordable manufacturing have been made possible by organic electronics. A subgroup of organic electronics known as organic light emitting diodes (OLEDs) have shown exponential growth in a variety of applications. The performance of these devices is decided by considering the activity of various parameters such as current efficiency, luminescence, power efficiency and external quantum efficiency (EQE). The applications of OLEDs are frequently seen in fields like biological sensors, displays, healthcare, and other critical sectors. This article provides a thorough summary of the developments made in the last decade in OLED real-time applications. The performance of AMOLED, TEOLED, and QD-OLED displays—three types of OLED-based displays—has been meticulously recorded in discussions on their progress. Over the past few years, there has been a significant increase in the use of OLEDs in the biomedical field. Additionally, the performance of a number of devices seen in many biomedical domains—such as wearable sensors and optogenetics—has been highlighted in this article. The purpose of this paper is to educate the next generation of researchers about the versatility and potential applications of OLED devices in the years to come.
