Abstract
A control circuit and a method for maintaining light transmittance of an electrochromic device are revealed. An input power source is turned off once a current input into an electrochromic device is decreased to a preset value. Then a voltage between two electrodes of the electrochromic device is detected. When the voltage between two electrodes of the electrochromic device is dropped to a preset value, the input power source is restored. According to the above steps, the coloration of the electrochromic device is maintained within a preset range. Thus light transmittance of the electrochromic device is kept at a certain range.
