Displays are basic building blocks of modern electronics^,. Integrating displays into textiles offers exciting opportunities for smart electronic textiles—the ultimate goal of wearable technology, poised to change the way in which we interact with electronic devices^{, , –}. Display textiles serve to bridge human–machine interactions^{, –}, offering, for instance, a real-time communication tool for individuals with voice or speech difficulties. Electronic textiles capable of communicating, sensing^, and supplying electricity^, have been reported previously. However, textiles with functional, large-area displays have not yet been achieved, because it is challenging to obtain small illuminating units that are both durable and easy to assemble over a wide area. Here we report a 6-metre-long, 25-centimetre-wide display textile containing 5 × 10⁵ electroluminescent units spaced approximately 800 micrometres apart. Weaving conductive weft …
