Recent Progress in Stretchable OLED Design and Applications

Abstract

With the recently rapid development of flexible electronics, stretchable OLEDs has become a significant direction to study because of its strong potential, like its ultra-thin structure, self-emissive nature, bendability, and stretchability. This new technology not only overcomes the limitations of traditional rigid screens, but also provides new opportunities in developing other fields, for example healthcare and human-computer interaction. From this perspective, the existing technology of OLED and its applications in different fields deserve attention. Firstly, it introduces the laser programming Buckling Process, three different island-bridge structures, Fold Bridge and Curved Bridge, Serpentine Bridge and Fractal Bridge, and talks about the Intrinsically stretchable materials. It then gives a few examples of applications in different fields, including Heart rate and blood oxygen monitoring, Variable-size screens and wearable devices and Phototherapy. This article not only makes a conclusion of current technological achievements and challenges of stretchable OLEDs but also makes a foundation for the future development of this field.
