Abstract
Intrinsically and fully stretchable active-matrix-driven displays are an important element to skin electronics that can be applied to many exciting emerging fields, such as wearable electronics, consumer electronics and biomedical devices. Here, we report for the first time a fully stretchable active-matrix-driven organic light-emitting electrochemical cell (AMOLEC) array that serves as a skin display device. Briefly, this array is comprised of an all solution-processed vertically integrated stretchable organic thin-film transistor (OTFT) active-matrix and a stretchable light-emitting electrochemical cell (LEC) array, all of which are enabled by the development of chemically orthogonal and intrinsically stretchable electronic and optical materials. Our resulting AMOLEC array can be readily bent, twisted and stretched without affecting its device performance. When mounted on skin the AMOLEC array can tolerant to repeated cycles at 30% strain. This work demonstrates the feasibility of skin applied displays and lays the foundation for further materials development.
