A Full‐Color Textile Display with 122% sRGB Gamut by Designing Three‐Primary‐Color Interwoven Pixels

Textile displays—renowned for inherent flexibility and breathability—have emerged as a transformative platform for next‐generation wearables and IoT integration. Despite substantial advancements, achieving dynamically tunable color display remains a critical challenge for effective information interaction. Here, this limitation is addressed through a woven architecture that integrates luminescent warp fibers with light‐conversion conductive weft fibers, creating a three‐primary‐color electroluminescent pixel array where each unit contains precisely arranged red (R), green (G), and blue (B) interlaced subpixels. These subpixels demonstrate exceptional spectral purity with full‐width at half‐maximum values as low as 37 nm—comparable to quantum dot light‐emitting diodes. The resultant pixel units achieve full‐color display with a color gamut covering 122% of the sRGB standard, representing a 344% enhancement over conventional alternating current electroluminescence devices. Standard‐like white light emission is achieved through precise control of RGB luminance ratios. A 5 × 5 cm 2 prototype textile display demonstrates multicolored text/image displaying via row scanning driving circuitry, while system‐level integration with fiber biosensors enables health monitoring through color‐coded heart rate visualization. This textile display is stable and durable to withstand 1,000 cycles of deformations like bending, stretching, twisting, and pressing. This work establishes a material‐to‐system framework for seamlessly embedding color displays into textiles.
