Abstract: This disclosure provides systems, methods, and apparatus for generating images on a display. Images are generated by displaying, for a first color, a first number of subframes at a full intensity level and a second number of subframes at reduced intensity levels. A third number of subframes of a second color are displayed at a full illumination level and a fourth number of subframes of the second color are displayed at reduced illumination levels. The number of subframes of the second color shown at reduced illumination levels is fewer than the number of subframes of the first color shown at reduced intensity levels.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for forming an image on a display in a display device including a plurality of backlight segments. Each backlight segment is capable of illuminating a respective illumination display segment of a plurality of illumination display segments. In one aspect, a controller associated with the display device is capable of decomposing an image frame into a plurality of frame segments to be displayed on the plurality of illumination display segments. The controller can determine a separate frame segment specific contributing color (FSSCC) for each frame segment based on content of the respective frame segment and a criterion limiting the color difference between a pair of FSSCCs based on the spatial proximity of the respective display regions. The controller can display the image frame according to the plurality of determined FSSCCs.

Abstract: This disclosure provides systems, methods, and apparatus for generating images on a display. A multi-primary display can include control logic that converts input image data into the multi-primary color space employed by the display by mapping the input pixel values into the XYZ color space according to a gamut mapping function and then decomposing the XYZ tristimulus values into color subfields associated with the display's primary colors. For example, such a process can be used to covert image frames encoded in an RGB color space into a RGBW color space. In some implementations, the control logic can adapt the gamut mapping and/or the decomposition processes based on a saturation level of the image being processed.

Abstract: This disclosure provides systems, methods and apparatus for providing relatively thinner and less stiff compliant beams for a shutter assembly. A protective coating is deposited and patterned over the shutter assembly before it is released from a sacrificial mold over which the shutter assembly is formed. Because some primary surfaces of the compliant beams are in contact with the sacrificial mold, these primary surfaces are not coated with the protective coating. Therefore, when the shutter assembly is finally released, the resulting compliant beams are relatively thinner and less stiff providing a reduction in an actuation voltage used to operate the shutter assembly. In some instances, the protective coating is patterned into discontinuous segments before release.

Abstract translation: 本公开提供了用于为快门组件提供相对较薄且较不硬的柔性梁的系统，方法和装置。 在从快门组件形成的牺牲模具释放之前，将保护涂层沉积并在其上形成图案。 由于柔性梁的一些主表面与牺牲模具接触，所以这些主表面没有涂覆保护涂层。 因此，当快门组件最终被释放时，所产生的柔性梁相对较薄并且较不硬，从而降低用于操作闸板组件的致动电压。 在一些情况下，保护性涂层在释放之前被图案化成不连续段。
