    Abstract: The disclosed waveguide display device may include a waveguide and one or more projector assemblies configured to project image light into the waveguide, where each of the one or more projector assemblies includes a first monochromatic emitter array having a plurality of emitters of a first color disposed in a two-dimensional configuration and a second monochromatic emitter array having a plurality of emitters of a second color disposed in a two-dimensional configuration. The display device may also include at least one application specific integrated circuit (ASIC) configured to drive the first and second monochromatic emitter arrays to emit images of the first and second color along a common axis, with the first color being different from the second color. Various other devices, systems, and methods are also disclosed.

    Abstract: A display device includes a display panel including a first array of light emitters having a first spacing in a first emission region of the display panel and a second array of light emitters having a second spacing in a second emission region of the display panel. The second spacing is distinct from the first spacing. The display device includes an optical filter including a first filter region and a second filter region. The first filter region changes distribution of first light from the first array of light emitters impinging on the first filter region so that the first light has a first distribution after passing through the first filter region. The second filter region changes distribution of second light from the second array of light emitters impinging on the second filter region so that the second light has a second distribution after passing through the second filter region.

    Abstract: A display device includes a display panel having a first emission region and a second emission region that surrounds the first emission region. The display device includes a first plurality of light emitters arranged in the first emission region, a plurality of activation lines for the first emission region, a second plurality of light emitters arranged in the second emission region, and a plurality of activation lines for the second emission region. A single activation line of the plurality of activation lines for the first emission region is electrically coupled with a first number of light emitters in the first emission region and a single activation line of the plurality of activation lines for the second emission region is electrically coupled with a second number, distinct from the first number, of light emitters in the second emission region.

    Abstract: Embodiments relate to nanoporous copper interconnects on a first body for electrically connecting to a second body. To fabricate the nanoporous copper interconnect, a zinc-copper alloy is deposited on recesses on the surface of the first body, and then the zinc is removed from the zinc-copper alloy to obtain nanoporous copper. The first body and the second body can be attached using bonding between oxide surfaces of the two bodies or be provided with underfill between the two bodies. The nanoporous copper electrically connects to an active layer or electrical components of the first body and the second bodies. Using nanoporous copper as interconnects is advantageous, among other reasons, because it can be formed at a low temperature, it is compatible with a standard complementary metal-oxide-semiconductor (CMOS) process, it provides good electrical conductivity, and it is less likely to cause issues due to migration of material.
