Abstract:A portable electrochromic display window (7 cm × 5 cm) has been constructed using a polyaniline-coated SnO2 glass plate and an AlCl3(aq) melt. The window colour can be switched from dark green to yellow or colourless by applying a small voltage of −0.5 to 2.5 V. It exhibits a fast response time (ms) and a long cycle life (1000).
