Abstract
The invention relates to light modulators for use in display apparatus. In particular, the invention relates to methods for supporting and support structures for light modulators to reduce unwanted motion.
Claims28
A display apparatus, comprising:
- a modulator for selectively interacting with light in an optical path to form an image on the display apparatus;
- a controllable first actuator providing a first mechanical support providing a supportive connection from a first location on the modulator to a surface over which the modulator is supported;
- and
- a second mechanical support providing a supportive connection from a second location on the modulator to the surface,
- wherein the first actuator drives the shutter in a plane substantially parallel to the surface.

A method of manufacturing a display apparatus, comprising:
- etching a first surface to form a modulator for selectively interacting with light in an optical path;
- etching an actuator in the first surface connecting the modulator and an anchor, wherein the anchor and the actuator serve as a first mechanical support, physically supporting the modulator over a second surface and the actuator is configured to drive the shutter in a plane substantially parallel to the second surface;
- etching a second mechanical support into first surface connecting the modulator and a second anchor, the second mechanical support physically supporting the modulator over the second surface,
- wherein the first anchor and the second anchor are connected to two distinct locations on the second surface.
