Transmittance control method of electrochromic component

摘要

A transmittance control method of electrochromic element, mainly comprising the following step: firstly, a total current flux input required is obtained by adding current value of each second together by the relationship between different current value and different rate of change of the electrochromic element obtained in terms of the same transmittance and different input voltages, then the total current flux for fixed transmittance is input into the electrochromic element in usage so as to achieve a transmittance of fixed value. In this manner, the electrochromic element can quickly achieve a transmittance of fixed value in precise manner, without repeated adjustment. Further, there is not such case happened as to influence the accuracy of its transmittance even after aging time lapse.

1. A transmittance control method of electrochromic element comprising the following steps:
defining a target transmittance value; providing an input voltage and input current to said electrochromic element; obtaining a total current flux input required for achieving said target transmittance value by adding each incremental input current value of each second together to determine a relationship between different current values and different rate of changes of said electrochromic element obtained in terms of the same target transmittance value and different input voltages; and inputting said total current flux into said electrochromic element so as to achieve a transmittance equal to said target transmittance value.
