Microperturbation fluidic assembly systems and methods are provided for the fabrication of emissive panels. The method provides an emissive substrate with a top surface patterned to form an array of wells. A liquid suspension is formed over the emissive substrate top surface, comprising a first liquid and emissive elements. Using an array of micropores, a perturbation medium, which optionally includes emissive elements, is injected into the liquid suspension. The perturbation medium may be the first liquid, a second liquid, or a gas. A laminar flow is created in the liquid suspension along the top surface of the emissive substrate in response to the perturbation medium, and emissive elements are captured in the wells. The ejection of the perturbation medium can also be used to control the thickness of the liquid suspension overlying the top surface of the emissive substrate.

Methods for orientation and placement of computing devices are presented. Aspects include applying, using a viscous material application device, a layer of a viscous material to a surface of an object, the layer of the viscous material having a plurality of computing devices disposed therein. The layer of the viscous material is allowed to dry during a drying period, wherein each of the plurality of computing devices comprises a first material applied to a first side of each of the plurality of computing devices, the first material having a first characteristic. And each of the plurality of computing devices comprises a second material applied to a second side of each of the plurality of computing devices, the second material having a second characteristic. And each of the plurality of computing devices is configured to perform, during the drying period, a self-orientation operation.
