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.

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 generating images on a multi-primary 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 an intermediate color space according to a gamut mapping function and then decomposing the mapped pixel values into color subfields associated with the display's primary colors. The control logic can be configured to identify a lossy gamut mapping saturation parameter value to use in the gamut mapping process which results in a power-saving desaturated image that is perceived by the Human Visual System (HVS) as substantially maintaining its color fidelity.

Abstract: In one innovative aspect of the disclosure, a method includes patterning a first region and a first portion of a second region of a substrate using a first reticle. The method also includes patterning the second region and a first portion of the first region using a second reticle. The method additionally includes forming a first array of first patterned elements based on the patterning by the first reticle, and forming a second array of second patterned elements based on the patterning by the second reticle. In some implementations, each of the first and the second arrays are incomplete in each of the first portions. However, the first patterned elements in the first portion of the second region are complementary to the second patterned elements in the first portion of the second region. Similarly, the first patterned elements in the first portion of the first region are complementary to the second patterned elements in the first portion of the first region. In some such implementations, the combination of the first array and the second array form a complete array of patterned elements.

Abstract: This disclosure provides systems, methods and apparatus for reducing flicker in display devices. In one image formation process, the controller can determine a number of subframes to be displayed for a subfield based on a temperature of a display apparatus. In some implementations, the controller can determine dithering parameters based on the determined number of subframes, and perform dithering on pixel intensity values based on the determined dithering parameters. In some implementations, a vector error diffusion technique can be utilized for performing dithering. In some implementations the controller can determine drive voltages for light modulators and drive currents for light sources used for displaying the subframes, based on the temperature of the display apparatus.
