• Direct photolithography of electrochromic WO_x nanoparticles via in situ photo-induced ligand exchange is proposed and demonstrated.

• The highest resolution among inorganic electrochromics (< 4 µm) is achieved, which is promising in high-resolution non-emissive displays.

• The as-prepared device exhibits highly remarkable performance including rapid response, high coloration efficiency and durability.
