Abstract: 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.

Abstract: This disclosure provides systems, methods and apparatus for improving an aperture ratio of a display apparatus. In particular, display elements are configured to have a length that is greater in one dimension than that in the other dimension. This implementation can reduce overhead costs associated with components such as actuators and actuator circuitry and improves the aperture ratio. Furthermore, display elements within the display apparatus can be arranged in a staggered manner. The staggered arrangement improves the perceived display element density of the display apparatus. In some implementations, the display elements are staggered along the rows of the display apparatus, while in some other implementations, the display elements are staggered along the columns of the display apparatus. In some implementations, multiple image pixels in one dimension are utilized to generate signals for each display elements.

Abstract: This disclosure provides systems, methods and apparatus for reducing hotspots in backlit displays. Hotspot artifacts in multi-color backlit displays can be reduced by incorporating optical structures along the edges of light guides incorporated into the backlights. The optical structures are positioned adjacent to light emitting modules that emit light into the light guide. Light emitted from the light emitting modules passes through the optical structures before entering the light guide. Hotspot size can be reduced by appropriately configuring the shapes and sizes of these optical structures. In some implementations, the optical structures may include serrations along the side of the light guide adjacent to the light sources. In some other implementations, the optical structures may include dimples. Size of hotspots may also be reduced by reducing the distance between adjacent light sources of the same color.

Abstract: Displays having a plurality of shutter assemblies with movable shutters. Typically, the shutter assemblies are arranged in a grid of rows and columns, and the grid has a horizontal axis aligned with a horizontal axis of the display. The shutter assembly is aligned within the grid to have the axis of motion of respective shutters extend at an angle relative to the horizontal axis of the grid. In certain implementations, the shutter assemblies have a rectangular peripheral edge, and are arranged in the grid to have the square peripheral edge disposed at an angle relative to the horizontal axis of the grid. This can arrange the shutter assemblies into a diamond layout within the grid and place the shutter assemblies of adjacent columns into spatially offset rows of the grid. In some implementations, this increases the pixels per inch of the display, in other implementations, increases the aperture ratio.
