Abstract
Light-control panels including layered optical components are described in this application. An example of a light-control panel includes first, second, and third glazing layers, first and second switchable components extending between the first and second glazing layers, and a third switchable component extending between the second and third glazing layers. The switchable components include a polymer-dispersed liquid-crystal (PDLC) device having a clear state and a hazy state, a guest-host liquid-crystal (GHLC) device having a clear state and a tinted state, and a light-guide device having a clear state and a bright state.
