Abstract: This disclosure provides systems, methods and apparatus for forming microbolometers on glass substrates. In one aspect, the formation of microbolometers on glass substrates can reduce the size and cost of the resultant array and associated circuitry. In one aspect, a portion of the measurement and control circuitry can be formed by thin-film deposition on the glass substrate, while sensitive measurement and control circuitry can be formed on ancillary CMOS substrates. In one aspect, the microbolometers may be packaged using a variety of techniques, including a wafer-level packaging process or a pixel-level packaging process.

Abstract: This disclosure provides systems, methods and apparatus for three-dimensional (3-D) through-glass via inductors. In one aspect, the through-glass via inductor includes a glass substrate with a first cavity, a second cavity, and at least two through-glass vias. The through-glass vias include metal bars that are connected by a metal trace. The metal bars and the metal trace define the inductor, and each cavity is at least partially filled with magnetic material. The magnetic material can include a plurality of particles having an average diameter of less than about 20 nm. The first cavity can be inside the inductor and the second cavity can be outside inductor. In some implementations, the first and the second cavity can be vias that extend only partially through the glass substrate.

In one embodiment, a lighting device includes a light guide having a planar first surface, the light guide configured such that at least some ambient light enters the light guide through the first surface and propagates therein, and at least one light detector disposed along an edge of the light guide, the at least one detector optically coupled to the light guide to receive light propagating therein. The light detector can be configured to produce a control signal. In some embodiments, the lighting device also includes at least one light turning feature disposed on the first surface, the at least one light turning feature configured to direct light incident into the light guide through the first surface.

Abstract: 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.

Abstract: 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. In one aspect, a method includes processing the drive instructions for the plurality of display devices to produce a first color in a set of potential colors for the plurality of display devices, selecting a color for the first display device that approximates the produced first color, displaying the selected color with the first display device, determining an error between the selected color and the produced first color, and diffusing the error by displaying at least another color on at least a portion of the plurality of display devices.

Abstract: 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.

Abstract: An apparatus for displaying data includes a first array of display elements having a plurality of rows and columns, a second array display of display elements having a plurality of rows and columns, and a third array of display elements having a plurality of rows and columns. In some implementations, the third array is disposed between the first and second arrays. The apparatus further includes a first set of busses connected to supply display signals to columns of the first array, a second set of busses connected to supply display signals to columns of the second array, and a third set of busses connected to supply display signals to columns of the third array.

Abstract: Power efficient power supply regulator circuits are disclosed. The circuits are configured to modify their overhead current according to current load. This is particularly advantageous for use in display devices with widely varying current loads. Such displays include bi-stable displays, such as interferometric modulation displays, LCD displays, and DMD displays.
