Ultra low-field-emission stretchable electroluminescent devices enabled by a transparent and high-κ dielectric gel.

ABSTRACT: Stretchable displays are the key components for next-generation flexible electronics, playing a critical role in interactive human-machine interfaces. Stretchable alternating current electroluminescent devices, one of the most promising methods for achieving stretchable displays, face challenges such as high driving alternating voltages and frequencies. Herein, we employ a high-k dielectric gel as the emitting matrix, enabling a stretchable electroluminescent device with a turn-on voltage of 13 V (0.19 V µm^-1) at 50 Hz and a maximum luminance of 1944.7 cd m^-2 at 2.5 V µm^-1 with 1 kHz. Moreover, the gel-based devices exhibit a high elongation up to 600%. We further employ fluorescent electrodes to achieve multi-color display of Yellow, Green, and Red without
