SHUTTER-BASED LIGHT MODULATORS INCORPORATING INTEGRATED SIDEWALL REFLECTORS

摘要

This disclosure provides systems, methods, and apparatus for a MEMS display incorporating integrated sidewall reflectors. The display can include a light blocking component suspended over a substrate. The light blocking component can include an aperture in its surface that is parallel to the substrate. The display can include one or more sidewall reflectors positioned within the aperture. The one or more sidewall reflectors can be arranged at least partially normal to the surface of the light blocking component. Light that is directed through the aperture can be reflected off of the sidewall reflectors to escape from the display at a higher angle than would otherwise be possible.

主权项

1. A display apparatus, comprising:
a substrate; and a display element including:
a light blocking component suspended over the substrate, the light blocking component including:
an aperture formed through a surface of the light blocking component that is substantially parallel to the substrate, wherein the aperture has a perimeter edge, a first axis and a second axis, and wherein the first axis is longer than, and perpendicular to, the second axis; anda first sidewall positioned within the aperture and spaced away from the perimeter edge of the aperture, extending substantially parallel to the first axis and oriented at least partially normal to the surface of the light blocking component.
