摘要:
This disclosure provides systems, methods and apparatus for providing compact shutter assemblies. Shutter assemblies can be formed in a more compact fashion, allowing for higher pixel-per-inch displays, by incorporating shutters that during actuation pass over or under portions of the actuators that control those shutters.

This disclosure provides systems, methods and apparatus for displaying images. Some such apparatus include an array of display elements coupled to a substrate and an elevated aperture layer (EAL) suspended over the array of display elements. The EAL is coupled to the substrate, and includes, for each of the display elements, at least one aperture for allowing passage of light therethrough. Methods for manufacturing such apparatus include at least one of forming etch holes through the EAL, employing an at least partially sublimatable sacrificial mold, employing a two phase release process, and releasing the apparatus such that a portion of a sacrificial mold remains surrounding portions of the apparatus.

A display apparatus includes a backlight and an aperture layer that is positioned in front of the backlight and defines a plurality of apertures. The display apparatus also includes a microelectromechanical system (MEMS) light modulator configured to modulate light emitted by the backlight passing through the apertures to form an image on the display apparatus. The MEMS light modulator includes a shutter (1202) that has a light blocking portion having an aperture layer-facing surface and a front-facing surface and at least one depression (1207) formed in the light blocking portion. The width of the at least one depression accounts for at least 50% but less than 100% of a distance separating two edges of the shutter. In other embodiments the shutter perimeter surface is angled. Light leakage is mitigated.

This methods and devices described herein relate to displays and methods of manufacturing cold seal fluid-filled displays, including MEMS. The fluid substantially surrounds the moving components of the MEMS display to reduce the effects of stiction and to improve the optical and electromechanical performance of the display. The invention relates to a method for sealing a MEMS display at a lower temperature such that a vapor bubble does not form forms only at temperatures about 15° C. to about 20° C. below the seal temperature. In some embodiments, the MEMS display apparatus includes a first substrate, a second substrate separated from the first substrate by a gap and supporting an array of light modulators, a fluid substantially filling the gap, a plurality of spacers within the gap, and a sealing material joining the first substrate to the second substrate.

An electromechanical device comprises a substrate and an array of pixels (103) arranged on the substrate in rows and columns, a respective pixel having at least one respective light blocking element (202) and at least one electrode for actuating the light blocking element. A plurality of scan line interconnects (110) are formed on the substrate running in a first direction, and enable a plurality of pixels along the first direction to respond to data voltages. A plurality of data interconnects (112) are formed on the substrate running in a second direction perpendicular to the first direction, and provide data voltages to a plurality of pixels along the second direction. For a respective pixel: a first switch (2956) and a second switch (2966) connected in series, are formed on the substrate, and the first switch (2956) and second switch (2966) together connect an energy source to at least one of a light blocking element and the at least one electrode. A data switch (2957) is coupled to a corresponding one of the scan line interconnects (2946) and a corresponding one of the data interconnects (2948) for controlling movement of the light blocking element.
