Methods and apparatus for bi-stable actuation of displays
First Claim
Patent Images
1. 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.

35. 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. - View Dependent Claims (36, 37, 38)
