AB  - Flexible, lightweight, low-power, and low-cost displays are an active area of 
      interest in the electronics community. In this work, we have developed a 
      composite electrothermochromic material consisting of silver nanowires (Ag NWs) 
      and thermochromic powders, which exhibits reversible color (phase) change during 
      biasing due to Joule heating. A wide variety of color combinations are possible 
      with suitable thermochromic material selection. We have formulated this composite 
      material as a printable ink so that patterned deposition can be achieved in a 
      single step. A low processing temperature of 100  degrees C makes the composite 
      compatible with a wide range of flexible substrates such as paper and 
      polyethylene terephthalate (PET). The material (encapsulated with 
      polydimethylsiloxane (PDMS)) exhibits good flexibility and is observed to be 
      functional after 10 000 bending cycles with <7% resistance change. We have 
      fabricated a low-power seven-segment color display to show the material's 
      suitability for practical display applications. We have also demonstrated that 
      the same layer can function as a display and as a touch sensor because of its 
      conducting and chromatic properties without additional active layers on top. The 
      material is suitable for the fabrication of low-cost, flexible touch color 
      displays for interactive electronic readers, digital posters, and flexible 
      digital signboards.
