Light modulator, light modulator method and smart glazing

A light modulator method comprising:

• providing a light modulator comprising:
• a first substrate and a second substrate, the first and second substrates being arranged with inner sides opposite to each other, multiple electrodes being applied to the inner side of each of the first and second substrates, each of the multiple electrodes being arranged in a pattern across the substrate, the multiple electrodes each comprising
• a multiple of main-lines extending across the substrate in a first direction, the multiple of main-lines of the multiple electrodes being arranged alternatingly with respect to each other on the substrate;
• an optical layer between at least the first and second substrate, the optical layer comprising
• a fluid comprising particles, wherein the particles are electrically charged or chargeable, and wherein the particles are adapted to absorb or reflect light;
• at least one current sensing circuit connected to an electrode on a substrate, the current sensing circuit being configured to measure a current in the electrode to which it is connected;
• receiving at least one current sensing signal from the at least one current sensing circuits indicating current in a corresponding electrode,
• determining driving signals for the electrodes from the at least one current sensing signals and from a target transparency or reflectivity, and
• transmitting the driving signal to the light modulator for applying an electric potential to the multiple electrodes according to the driving signal to obtain an electro-magnetic field between the multiple electrodes, wherein the electro-magnetic field provides electrophoretic movement of the particles towards or from one of the multiple electrodes.
