Abstract: This disclosure provides systems, methods and apparatus for shutter-based EMS light modulators controlled by electrode actuators that include complementary sets of corrugations or teeth along the opposing beams of the actuators. The complementary sets of corrugations substantially engage one another when drawn together via an actuation voltage. By applying the actuation voltage across the opposing beams of such an actuator, the beams are drawn together both by the electromotive force resulting from the electric field acting between the portions of the beams that are substantially perpendicular to the direction of actuation of the actuator, and by fringing fields between the sides of the corrugations, which are substantially parallel to the direction of actuation. The additional fringing fields provide for increased electromotive force for a given input voltage.

Abstract: This disclosure provides systems, methods and apparatus for a MEMS display apparatus incorporating a tiered backplane slot structure. The backplane can include two or more light-blocking layers defining optical windows and positioned at different heights. Light can pass through the optical windows of the display apparatus at an angle. In some implementations, the angle can be based on the index of refraction of a transparent material inside the display apparatus. The transmission of off-axis and on-axis light can be improved by varying the widths of the optical windows in each layer of the backplane. In some implementations, the difference in the widths of optical windows of adjacent layers can be substantially equal to the separation distance between the layers.

Abstract: This disclosure provides systems, methods, non-transitory computer readable storage media, and apparatus for displaying images using hue-based frame-specific contributing colors (FSCCs). In one aspect, an input is configured to receive image data corresponding to a current image frame. Contributing color selection logic is configured, based on received image data, to obtain a set of FSCCs for use in conjunction with a set of frame-independent contributing colors (FICCs) to generate the current or a subsequent image frame on a display. The set of FSCCs are obtained from determining the dominant hues in the image frame. The image frame is displayed such that subframes associated with displaying the FSCCs have weights that are greater than the subframes associated with displaying the FICCs.

Abstract: Systems, apparatuses and methods are provided for increasing the aperture ratio of a display by increasing the total travel distance of respective light modulating bodies in a display while maintaining fast switching speeds. Increasing the total travel distance allows for a larger aperture ratio in a display, which provides greater power savings and increased display brightness. The total travel distance of a light modulating body includes the distance the body travels from an open position to a closed position, and vice-versa. In one example, the travel distance of a light modulating body (e.g., any of the light modulators as described above) is asymmetric: from a neutral position, the body travels a greater distance in a first direction than in a second direction.
