A cover is physically coupled to the light guide and disposed over the turning microstructure. An interlayer is between the cover and the light guide, wherein the interlayer physically couples the cover to the light guide. A plurality of open regions is between the interlayer and the plurality of indentations. Various embodiments include methods of coupling the cover to the light guide while preserving open regions between the cover and plurality of indentations. | 05-09-2013 |

20130127881 | SYSTEMS, DEVICES, AND METHODS FOR DRIVING A DISPLAY - This disclosure provides systems, methods and apparatus for writing data to a display. The frame rate is improved by simultaneously and independently writing data to multiple common lines of the display. In some implementations, lines of common color are written simultaneously. In some implementations, more common lines of lower visual importance are written simultaneously than common lines of higher visual importance. In these implementations, colors of higher visual importance can be displayed at a higher resolution to maintain good image quality while still improving frame rate. Display element electrodes may be coupled along common lines in various ways to implement simultaneous writing to multiple common lines. | 05-23-2013 |
20130135335 | METHODS AND APPARATUS FOR INTERPOLATING COLORS - This disclosure provides methods, apparatus, and computer programs encoded on computer storage media for displaying a target color on an electronic display having display devices capable of displaying a set of native colors. In one aspect, the method includes identifying a plurality of weights including at least a first weight and one or more other weights, selecting a first color from the set of native colors that is closest to the target color and assigning it to the first weight, determining an error between the first color and the target color, recursively assigning a subsequent color from the set of native colors to the one or more other weights. Each subsequent color is selected based on the target color and an error normalized by previously assigned weights. The method also displays each assigned color according to its weight on the electronic display. | 05-30-2013 |
20130135364 | METHODS AND APPARATUS FOR INTERPOLATING COLORS - This disclosure provides methods, apparatus, and computer programs encoded on computer storage media for converting drive instructions for a plurality of display devices to drive instructions for a first display device.

20130176518 | BACK-TO-BACK DISPLAYS - Two-sided, back-to-back displays are formed by sealing the backplates of two displays against one another. Mechanical parameters of the backplates, e.g., stiffness and strength, do not meet the requirements for standalone one-sided displays which are otherwise similar to the two displays. However, when sealed against one another, the backplates reinforce each other to meet or exceed the requirements for both one-sided and two-sided displays. The presence of backplates on each of the constituent one-sided displays allows one or both of those displays to be individually tested, thereby increasing the production yield of the back-to-back displays. The display elements of the displays can comprise interferometric modulators. | 07-11-2013 |
