Professor Soo-Seok Choi’s Research Team Publishes Cover Article in Advanced Materials Technologies on Stretchable Multi-Pixel Color Matrix Driving

A research team led by Professor Soo-Seok Choi from POSTECH’s Department of Electrical Engineering, comprising PhD candidates Jun-Hyuk Shin (first author), Seung-Min Nam, and Sang-Hyun Han, as well as master’s students Ji-Yoon Park and Chae-Hyun Kwon, has been recognized for their groundbreaking study on stretchable color devices. Their research has been selected as an Inside Back Cover article in the interdisciplinary journal Advanced Materials Technologies and will be officially published on December 21.

Research Highlights

The study extends the concept of intrinsic stretchable color-changing devices from single-pixel designs to a multi-pixel system capable of uniform and precise color control. The team successfully implemented Segmented Matrix Driving technology, enabling display functionality in stretchable systems.

This innovative technology represents the first demonstration of a stretchable multi-pixel system with intrinsic color changes under mechanical deformation, providing a significant step forward in developing stretchable displays and flexible electronics.

Significance

This achievement highlights a major advancement in stretchable display technology, addressing the challenges of uniform control and scalability. The proposed system opens up new possibilities for applications in wearable electronics, electronic skins, and next-generation flexible displays.

Being featured as a cover article in Advanced Materials Technologies further underscores the importance and potential impact of this research, solidifying POSTECH’s position as a global leader in cutting-edge materials and device engineering.
