摘要： A direct-view display includes an array of MEMS light modulators and a control matrix formed on a transparent substrate, where each light modulator can be driven into at least two states, and a controller for controlling the states of each light modulator in the array. The control matrix transmits data and actuation voltages to the array. The controller includes an input, a processor, a memory, and an output. The input receives image data encoding an image frame for display. The processor derives a plurality of sub-frame data sets from the image data, where each sub-frame data set indicates desired states of light modulators in multiple rows and multiple columns of the array. The memory stores the plurality of sub-frame data sets. The output outputs the plurality of sub-frame data sets according to an output sequence to drive light modulators into the states indicated in the sub-frame data sets.

摘要： This disclosure provides systems, methods and apparatus for displaying images. One such apparatus includes a substrate, an elevated aperture layer (EAL) defining a plurality of apertures formed therethrough, a plurality of anchors for supporting the EAL over the substrate and a plurality of display elements positioned between the substrate and the EAL. Each of the display elements may correspond to at least one respective aperture of the plurality of apertures defined by the EAL. Each display element also includes a movable portion supported over the substrate by a corresponding anchor supporting the EAL over the substrate. In some implementations, one or more light dispersion elements may be disposed in optical paths passing through the apertures defined by the EAL.

摘要： 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.

摘要： An illumination device, comprising a reflective optical cavity (2104, 2116) including a plurality of light-transmissive regions (2108) through which light can escape the reflective optical cavity (2104, 2116); a light source (2118) arranged to introduce the light into the reflective optical cavity (2104, 2116); a plurality of light modulators (2102), each having at least first and second states, wherein, in the first state, a light modulator (2102) obstructs a corresponding light-transmissive region (2108) thereby preventing light introduced into the reflective optical cavity (2104, 2116) from illuminating an image pixel that corresponds to the light-transmissive region (2108), and in the second state, the light modulator (2102) allows light escaping the reflective optical cavity (2104, 2116) through the corresponding light-transmissive region (2108) to illuminate the image pixel corresponding to the light-transmissive region (2108).
