US Patent 12111556 Multi-segment electro-optic apparatus and control methods

An electro-optic device includes a first electrode electrically connecting with power supply circuitry. A second electrode is spaced from the first electrode and electrically connecting with the power supply circuitry. An electro-optic medium is disposed between the first electrode and the second electrode. At least one third electrode is disposed between the first electrode and the second electrode and electrically connecting with one of the first electrode and the second electrode via switching circuitry. The switching circuitry is operable to control an electrical current through the first electrode, the electro-optic medium, and the second electrode.
