Abstract
An optical stack includes a first variable element and a second variable element. The first variable element is configured to vary light transmission through the first variable element as a function of a first control signal. The second variable element is in series with the first variable element and is configured to vary light transmission through the second variable element as a function of a second control signal. A controller dynamically supplies the first control signal to the first variable element and supplies the second control signal to the second variable element.
