Abstract
A regulating device includes a voltage regulator configured to receive an input voltage and regulate an amplitude and a frequency of the input voltage to generate an electrical signal acting on the electric control functional layer; and a controller coupled to the voltage regulator and configured to receive a regulating signal, and to send a control signal to the voltage regulator according to the regulating signal to regulate the amplitude and the frequency of the input voltage, the control signal including an amplitude parameter and a frequency parameter of the voltage. Finer regulation of the optical characteristics of the electric control functional layer can be realized by introducing frequency regulation. Such finer regulation can bring about a more comfortable experience to human senses. At the same time, the realization of such fine regulation enables more diversified control of the electronic control function layer.
