Abstract
This study introduces a simplified fabrication method for implementing a TFT array on a cylindrical fiber, using only four masks and a low‐temperature process below 120 ℃. To overcome the limitations of the one‐dimensional cylindrical fiber structure, the study emphasizes the design and implementation of a three‐dimensional backplane, utilizing the side or bottom surfaces of the fiber to address patterning and shadowing challenges. The proposed TFTs, part of the 2T1C pixel circuit within the fiber, exhibit electrical properties suitable for driving OLEDs.
