Display system with phase oriented reflective control

Abstract:

A vehicle display mirror system is disclosed. The system comprises a display device and a reflecting polarizer. The display device is operable to display image data on a display surface as display light. The reflecting polarizer comprises a light receiving surface proximate the display surface and configured to output the display light in a first polarization from an emitting surface. The system further comprises a liquid crystal element, a polarizing element, and a controller. The controller is in communication with the liquid crystal element and configured to selectively align a liquid crystal material to pass the display light through the liquid crystal element and deactivate the liquid crystal element to adjust a received light from the first polarization to a second polarization and reflect the second polarization from the emitting surface.
