Patent number: 11278900Abstract: 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.Type: GrantFiled: January 8, 2020Date of Patent: March 22, 2022Assignee: eLux, Inc.Inventors: Kenji Sasaki, Shu-han Yu, Paul J.
