Water stable and matrix addressable OLED fiber textiles for wearable displays with large emission area

Organic light-emitting diode(OLED)fibers with favorable electroluminescence properties and interconnectable pixel configurations have represented the potential for wearable electronic textile displays.Nevertheless,the current technology of OLED fiber-based textile displays still leaves to be desired due to several challenges,including limited emission area and lack of encapsulation systems.Here we present a fibrous OLED textile display that can attain a large emission area and long-term stability by implementing addressable networks comprised of integrated phosphorescence OLED fibers and by designing multilayer encapsulations.The integrated fiber configuration offers decoupled functional fiber surfaces for an interconnectable 1-dimensional OLED pixel array and a data-addressing conductor.Tailored triadic metal/ultrathin oxide/polymer multilayer enables not only the oxygen/water permeation inhibition but also the controllable conductive channels of dielectric antifuses.Together with reliable bending stability,the long-term operation of OLED textiles in water manifests the feasibility of the present device concept toward water-resistant full-emitting-area fibrous textile displays.
