Display apparatus including MEMS devices
First Claim
1. A display apparatus, comprising:
- one or more micro-electro-mechanical system (MEMS) devices, wherein at least one of the MEMS devices includes;
a first electrode including a partially reflective surface;
a second electrode including a partially or completely reflective surface and disposed substantially parallel to the first electrode; and
an analog actuation arrangement coupled to the first electrode, the second electrode or both the first and second electrodes to cause movement of the first electrode from a start position to a selected one of a plurality of end positions, responsive to a selected application of an actuation voltage, to cause the at least one MEMS device to selectively output a reflection of light in a selected wavelength or no reflection of the light,wherein the at least one MEMS device further includes a reflectance control panel disposed underneath the second electrode, wherein the reflectance control panel includes a reflective plate and an additional electrode configured to control reflectance of the reflective plate.

Abstract
Embodiments of the present disclosure provide techniques and configurations for a display apparatus. In one embodiment, the apparatus may include one or more micro-electro-mechanical system (MEMS) devices. The MEMS device may include a first electrode including a partially reflective surface, a second electrode including a partially or completely reflective surface and disposed substantially parallel to the first electrode, and an analog actuation arrangement coupled to the first electrode, the second electrode or both the first and second electrodes to cause movement of the first electrode from a start position to a selected position of a plurality of end positions, responsive to a selected application of an actuation voltage, to cause the MEMS device to selectively output a reflection of a light in a selected wavelength, or no reflection of the light. Other embodiments may be described and/or claimed.

11. A display apparatus, comprising:
-
one or more micro-electro-mechanical system (MEMS) devices, wherein at least one of the one or more MEMS devices includes; a first electrode including a partially reflective surface; a second electrode including a partially or completely reflective surface and disposed on one side of the first electrode, substantially parallel to the first electrode; and a third electrode disposed on an opposite side of the first electrode, substantially parallel to the first electrode; wherein the first electrode is at a start position between the second and third electrodes, when no actuation voltage is applied to either the second or the third electrode, and moveable from the start position to a first or a second position between the second and third electrodes, responsive to selective application of the actuation voltage to either the third or the second electrode, to cause the at least one MEMS device to respectively output a first reflection of light in a first wavelength, a second reflection of the light in a second wavelength, different from the first wavelength, or no reflection of the light, and wherein the at least one MEMS device further includes a reflectance control panel disposed underneath the second electrode, wherein the reflectance control panel includes a reflective plate and an additional electrode configured to control reflectance of the reflective plate. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
