Abstract
A first movable polarizing plate and a second movable polarizing plate are located on a traveling path of light emitted from a light source and having passed through a stable polarizing plate. The first movable polarizing plate is formed with a first display pattern allowing the light to pass through. The second movable polarizing plate is formed with a second display pattern allowing the light to pass through. An actuation mechanism causes a direction of a polarization axis of only one of the first movable polarizing plate and the second movable polarizing plate to be different from a direction of a polarization axis of the stable polarizing plate.
Claims6
A display switching device, comprising:
- a plurality of movable polarizing plates located on a traveling path of light emitted from a light source and having passed through a stable polarizing plate, and each of which is formed with a display pattern allowing the light to pass through;
- and
- an actuation mechanism configured to cause a direction of a polarization axis of only one of the movable polarizing plates to be different from a direction of a polarization axis of the stable polarizing plate.
