The preparation of switchable, high‐resolution (360 dpi) electrochromic pictures in sealed transparent and reflective cells is described. Viologens were inkjet printed, chemically amplified, and crosslinked on mesoporous TiO 2 thick‐film electrodes (see Figure). As a counter electrode, e.g., optically transparent and electrochemically fast CeO 2 on mesoporous antimony tin oxide was used.
