Abstract
The invention relates to mechanically bi-stable shutter assemblies for use in display apparatus to form images.
Claims38
A display apparatus comprising:
- a shutter for interacting with a light in an optical path to form an image on the display apparatus;
- a voltage input for receiving an actuation potential;
- and
- an actuator, responsive to an actuation potential being applied to the voltage input, for moving the shutter from a first mechanically stable position in a plane to a second mechanically stable position in the plane.
1 more element
A method of forming an image on a display apparatus, comprising:
- selectively applying an actuation potential to a voltage input;
- moving a shutter, in response to the application of the actuation potential, in a plane, from a first mechanically stable position to a second mechanically stable position, thereby permitting light to contribute to the formation of an image.
