Method for controlling light transmittance of electrochromic element

摘要: The invention relates to a method for controlling light transmittance of an electrochromic element. Primarily, form the relationship between different current values and change rates generated by input voltages under condition that element has same transmittance, per second are added learn total electric magnitude which should be input. Thus when is used, it can fixed so as have transmittance. Accordingly, achieve rapidly accurately without repeat adjustment. Furthermore, accuracy will not affected over time aging phenomenon, increase thesubstantial efficiency whole implementation.
