An emissive panel and associated assembly method are provided. The method provides an emissive substrate having an insulating layer with a top surface and a back surface, and a dielectric layer overlying the insulating layer patterned to form a plurality of wells. Each well has a bottom surface formed on the insulating layer top surface with a first electrical interface electrically connected to a first conductive pressure channel (CPC). The CPCs are each made up of a pressure via with sidewalls formed between the well bottom surface and the insulating layer back surface. A metal layer coats the sidewalls, and a medium flow passage formed interior to the metal layer. The method uses negative pressure through the CPCs to help capture emissive elements in a liquid flow deposition process.

Printing complex electronic circuits using a printable solution defined by a patterned hydrophobic layer

A programmable circuit includes an array of printed groups of microscopic transistors or diodes. The devices are pre-formed and printed as an ink and cured. A patterned hydrophobic layer defines the locations of the printed dots of the devices. The devices in each group are connected in parallel so that each group acts as a single device. Each group has at least one electrical lead that terminates in a patch area on the substrate. An interconnection conductor pattern interconnects at least some of the leads of the groups in the patch area to create logic circuits for a customized application of the generic circuit. The groups may also be interconnected to be logic gates, and the gate leads terminate in the patch area. The interconnection conductor pattern then interconnects the gates for form complex logic circuits.
