Abstract:
An improved device switchable between reflective and display states comprising an optical element and a display element. The optical element comprising a liquid crystal medium disposed between first and second substrates. The optical element may further comprise a first electrode, a second electrode, an absorptive polarizer, and a reflective polarizer. The first electrode and the absorptive polarizer may be disposed in a first direction relative the liquid crystal medium. Similarly, the second electrode and the reflective polarizer may be disposed in a second direction relative the liquid crystal medium. The second direction is opposite the first direction. In some embodiments, one or more of the absorptive and reflective polarizers may be further disposed between the first and second substrates. The display may be disposed in the first direction relative the optical element. Additionally, the device may further comprise a housing. In some embodiments, the housing may not have a bezel.
