Abstract: A variable transmission device forms a surface area including a plurality of electro-optic elements and first and second electrodes electrically connecting with a power supply circuit. An electro-optic medium is disposed between the first and second electrodes. A plurality of third electrodes is disposed between the first and second electrodes. A control circuit is electrically connected to one of the at least one first electrode and the at least one second electrode and configured to supply control signals to the electro-optic elements.

Abstract: 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.

Abstract: A display assembly for a vehicle is disclosed. The display assembly may include a variable transmittance panel in connection with a support structure connecting the display assembly to the vehicle. The variable transmittance panel may include an electro-optic element configured to vary in transmittance in response to a transmittance control signal and a display that is at least partially light transmissive. The display may include opposing display surfaces on a first side and a second side. The first side is disposed adjacent to the electro-optic element. In operation, the display may output display content as display light from both the first side and the second side. The visibility of the display light output from the first side may be controlled or adjusted by the transmittance of the electro-optic element.
