Abstract: An example of a pixel module comprises a module substrate having light emitters disposed on a light-emitter surface and a controller disposed on a controller surface opposed to the light-emitter surface. At least one module electrode is electrically connected to the controller and at least one module electrode is electrically connected to each light emitter. An example of a pixel-module wafer comprises a module source wafer comprising sacrificial portions and module anchors, each sacrificial portion laterally separated from an adjacent sacrificial portion by a module anchor and a pixel module disposed entirely over each sacrificial portion. At least one module tether physically connects each of the pixel modules to at least one of the module anchors. An example of a pixel-module display comprises a display substrate, pixel modules disposed on the display substrate and display electrodes disposed on the display substrate, each display electrode electrically connected to a module electrode.

Abstract: Methods, apparatus, systems, and articles of manufacture to generate 3D point clouds based on spatiotemporal light patterns are disclosed. A controller includes processor circuitry to execute the instructions to generate a series of light patterns based on a set of light pattern tiles. Each of the light pattern tiles is defined by a different arrangement of illuminated pixels. Each of the light patterns is defined by a different arrangement of the light pattern tiles. The processor circuitry is to instruct a projector to project the series of light patterns; instruct an image sensor to capture a series of images of reflections of the series of light patterns; and generate a three-dimensional point cloud based on the series of captured images.
