Abstract: This disclosure provides systems, methods and apparatus for optically obstructing inoperable display elements in a display apparatus. In one aspect, a display apparatus can include a plurality of display elements each having a shutter suspended over a substrate. The shutters can be capable of moving into and out of an optical path aligned with at least one aperture formed in a substrate. When a display element is inoperable, the shutter associated with the display element may be unable to block light passing through the aperture. To improve the quality of images formed on the display apparatus, the aperture associated with the inoperable display element can be optically obstructed, so that light directed toward the aperture is blocked even if the shutter is stuck in the open position. In some implementations, the aperture may be optically obstructed by a light-blocking pigment deposited over the aperture.

Abstract: This disclosure provides systems, methods and apparatus for a shutter-based light modulator. The shutter includes at least three depressions extending outward from the surface of the shutter. Any two adjacent depressions of the at least three depressions define a gap therebetween to reduce damping forces caused by fluids in which the shutter is immersed. In some implementations, the at least three depressions can be aligned into more than one row, each row including more than two of the at least three depressions, along the surface of the shutter. In some implementations, to improve structural stability of the shutter, depressions in one row are staggered with respect to depressions in another row.

Abstract: This disclosure provides systems, methods, and apparatus for displaying images on a display. An image-forming region is formed by a plurality of display elements each having a movable shutter component. Images are generated by controlling the shutter component of each of the plurality of display elements to move into open or closed positions depending on a desired light output intensity. Optically inactive display elements are positioned outside of the image-forming region. The position of the movable shutter component of each optically inactive display element is selected based on the next state of the movable component of at least one display element. The optically inactive display elements can increase the speed of the shutter components of display elements by displacing a fluid that surrounds the display elements and the optically inactive display elements.

In one aspect, the systems include a substrate made of a low dielectric material, such as glass. A layer of semiconductor material extends, substantially continuously over a surface of the substrate and includes an array of display elements that modulate light to form an image and a movable diaphragm that detects acoustic signals. The diaphragm is held away from the substrate by springs that include beams having an aspect ratio of about four to one.

Abstract: This disclosure provides systems, methods, and apparatus for supporting a bezel region of a display device. A display device can include a first substrate and a second substrate coupled by an edge seal. An array of shutter-based display elements can be positioned within an image forming region between the first and second substrates. A plurality of mechanical supports can be positioned within a bezel region outside of the image-rendering region and within the edge seal. Along a side of the bezel region that extends in a direction perpendicular to a direction of shutter motion, adjacent mechanical supports can be separated from one another by a gap that is longer than each of the mechanical supports in the direction perpendicular to the direction of shutter motion.

Abstract: This disclosure provides systems, methods and apparatus utilizing flexures in a display. In some implementations, an electromechanical systems (EMS) device can include flexures that have low stiffness along the axis of motion of a light modulator, and high stiffness in other directions. The flexures may include one or more beams mechanically coupling a MEMS structure to an anchor. The beams may be coupled to a hinge portion, the hinge portion being configured to suppress out of plane motion by the MEMS structure and the flexures. The flexures also may suppress out-of-plane motion using a stiffened portion. The stiffened portion can be mechanically coupled to the hinge portion or at least one beam of the flexure. By varying the cross-section geometry of the stiffened portion, the stiffness of the stiffened portion may be controlled to increase the force required to move the flexure in an out-of-plane direction.
