Device for operating functional elements having electrically controllable optical properties
A device having a functional element having electrically controllable optical properties, includes an electrical energy source having an output voltage U, a functional element having electrically controllable optical properties, and at least two supply lines, by means of which the electrical energy source and the functional element are connected. The output voltage U has an alternating voltage having a frequency f from 40 Hz to 210 Hz, a maximum amplitude Umax from 24 V to 100 V, and a slope in the range of the output voltage U between −80% Umax and 80% Umax from 0.05*Umax/100 μs to 0.1*Umax/100 μs and in the range of the output voltage U between 80% Umax and −80% Umax from −0.05*Umax/100 μs to −0.1*Umax/100 μs.
