Abstract
A method for control of electrochromic devices is revealed. First a duty cycle of PWM is changed to a preset Q value according to a signal detected by a detector while the electrochromic device is switched to the colored state. The Q value represents electric charge that corresponds to colored-state transmittance. Then turn off the PWM. Thus the response time for coloration and the transmittance of the electrochromic device are maintained within a preset range, without being affected by ambient temperature, setting time and aging of the materials used. Thus the electrochromic device is more convenient to use and having more practical value.
