•Electrochromic devices (ECDs) having a high switching speed and a good durability were developed with viologen-anchored TiO2 (VTO) nanoparticles and antimony-doped SnO2 (ATO) nanoparticles.•The fabricated single cell ECD showed a good stability after 30,000 cycles driving at 4 Hz speed.•The pre-reduction step of ATO counter electrodes and the thickness control of two electrodes make an increase of cell stability because of the charge balance of ECDs.•Also, 6×6 patterned array cells were designed to study the dynamic behaviour of their devices.•The switching charges using the ATO half cell made the “cross-talk” problem because of residual charges in the VTO layer. On the other hand, the driving method of 3 types shows blur-free images.
Electrochromic devices (ECDs) having a high switching speed and a good durability were developed with viologen-anchored TiO2 (VTO) nanoparticles and antimony-doped SnO2 (ATO) nanoparticles. The fabricated ECDs showed a good stability after 30,000 cycles driving at 4 Hz speed. Also, the dynamic behavior of their devices was studied using 6×6 patterned array cells. The driving tests of 4 types were used to understand the exact driving mechanism and to prevent the rapid blur problem.
