Abstract: In a flip-chip LED assembly having an array of LEDs formed on the same substrate, different LEDs of the array have different distances to the n-contacts of the assembly. This may cause current crowding as current has to spread from the n-contacts through the substrate to each the farthest LEDs of the LED array, requiring LEDs that are farther away to be driven with a higher voltage in order to receive a desired amount of current. To spread current more evenly through the LED assembly and reduce a voltage difference between the closest and farthest LEDs of the array, one or more additional n-contacts are formed within the LED array. In some embodiments, the n-contacts may replace a pixel of the LED array. In other embodiments, one or more p-contacts of the LED array are resized or repositioned to accommodate the additional n-contacts without sacrificing pixels of the LED array.

Abstract: A near-eye display assembly presented herein includes an electronic display, an optical assembly, and scanning assembly. The electronic display has a first resolution.

The scanning assembly shifts a direction of at least one of the light rays in accordance with emission instructions such that a virtual display is presented to the eye box, the virtual display having a second resolution greater than the first resolution. The display assembly can be implemented as a component of a head-mounted display of an artificial reality system.

Abstract: In one embodiment, a method includes, by a computing system, determining a sample point within a texture. The sample point corresponds to a specified output position in a display system. The method includes accessing texels in the texture that are used for determining properties of the sample point. Each identified texel includes a color and a transparency level. The method includes determining an interpolation optimization by comparing the colors and transparency levels of the identified texels. The method includes determining, according to the determined interpolation optimization, a pixel color and a pixel transparency level for the sample point using the identified texels. At least one of the pixel color or the pixel transparency level is determined by copying the colors or transparency levels of the texels, respectively, without performing interpolation. The method includes providing the determined pixel color and the determined pixel transparency level for the sample point for display.

Abstract: A tunable liquid crystal (LC) device includes an LC layer between a pair of reflectors forming an optical cavity. The reflectors include conductive layers for applying an electrical signal to the LC layer. One of the conductive layers may include an array of conductive pixels for spatially selective control of the effective refractive index of the LC layer. The phase delay introduced by the LC layer may be greatly increased or magnified by placing the LC layer into the optical cavity. This enables a substantial reduction of the LC layer thickness, which in its turn enables very tight pitches of the LC pixels, with a reduced inter-pixel crosstalk caused by fringing electric fields, as well as faster switching times. A tight-pitch, fast LC device may be used as a configurable hologram or a spatial light modulator.

The method also includes generating by the computing system a virtual environment including the virtual object by retrieving a model of the object and utilizing the model and the container effect to render a virtual object.

The disclosed systems can then modify design variables based on the determined performance metrics to explore the design space and generate a new aircraft model.

Abstract: An example device includes a nanovoided polymer element, which may be located at least in part between the electrodes. In some examples, the nanovoided polymer element may include anisotropic voids, including a gas, and separated from each other by polymer walls.

The nanovoids may be sufficiently small (e.g., below 1 micron in diameter or an analogous dimension), and/or the polymer walls may be sufficiently thin, such that the gas interchange between gas in the voids and gas absorbed by the polymer walls may occur faster than the response time, and in some examples, effectively instantaneously.
