Abstract

Smart textiles consist of discrete devices fabricated from—or incorporated onto—fibres. Despite the tremendous progress in smart textiles for lighting/display applications, a large scale approach for a smart display system with integrated multifunctional devices in traditional textile platforms has yet to be demonstrated. Here we report the realisation of a fully operational 46-inch smart textile lighting/display system consisting of RGB fibrous LEDs coupled with multifunctional fibre devices that are capable of wireless power transmission, touch sensing, photodetection, environmental/biosignal monitoring, and energy storage. The smart textile display system exhibits full freedom of form factors, including flexibility, bendability, and rollability as a vivid RGB lighting/grey-level-controlled full colour display apparatus with embedded fibre devices that are configured to provide external stimuli detection. Our systematic design and integration strategies are transformational and provide the foundation for realising highly functional smart lighting/display textiles over large area for revolutionary applications on smart homes and internet of things (IoT).

Highlights

Breakthroughs in materials[1–6] and process development[7–11] have enabled emerging smart textiles technologies based on electronics with new form factors
Smart or electronic textiles (e-textiles) consist of versatile electronic devices incorporated onto fibre substances[17–22], which have been focused on wearables[23–26]
To realise a broad range of multifunctionalities in a single smart textile display system, we integrated one output and six input devices, which are compatible with symmetric and asymmetric weaving pattern, including; (i) F-radio frequency antenna (F-RF), (ii) F-photodetector, (iii) F-touch sensor, (iv) F-temperature sensor, (v) F-biosensor module, and (vi) F-energy storage that assembled within a natural cotton textile platform
