Article Synopsis
- - Fiber-based organic light-emitting diodes (OLEDs) show great potential for making wearable textile displays due to their good electrical and mechanical properties, but active operation has been challenging due to difficulties in creating suitable fiber-based thin film transistors (TFTs).
- - Researchers developed 1D cylindrical fiber-based IGZO TFTs that achieve high electrical performance and flexibility through a novel four-stage fabrication process tailored for the fibers' characteristics.
- - The successful integration of fiber-based IGZO TFTs with fiber OLEDs suggests the possibility of creating fully textile AMOLED displays, indicating a significant step forward in wearable technology.
Laser lift-off (LLO) of ultrathin polyimide (PI) films is important in the manufacturing of ultrathin displays. However, conventional LLO technologies face challenges in separating the ultrathin PI films without causing mechanical and electrical damage to integrated devices. Here, we propose a graphene-enabled laser lift-off (GLLO) method to address the challenges.
