Abstract: A first product may be provided that comprises a substrate having a first surface, a first side, and a first edge where the first surface meets the first side; and a device disposed over the substrate, the device having a second side, where at least a first portion of the second side is disposed within 3 mm from the first edge of the substrate. The first product may further comprise a first barrier film that covers at least a portion of the first edge of the substrate, at least a portion of the first side of the substrate, and at least the first portion of the second side of the device.

Abstract: A method of forming microelectronic systems on a flexible substrate includes depositing a plurality of layers on one side of the flexible substrate. Each of the plurality of layers is deposited from one of a plurality of sources. A vertical projection of a perimeter of each one of the plurality of sources does not intersect the flexible substrate. The flexible substrate is in motion during the depositing the plurality of layers via a roll to roll feed and retrieval system.

Abstract: Techniques to fabricate and assemble a lighting system including multiple patterned OLED lighting panels to form a high-resolution macro image are provided. An image to be displayed is determined and divided into multiple portions. Patterned static OLED lighting panels that display each portion of the image are fabricated and assembled into a fixture to form a macro-image lighting system. The fixture may removably receive and hold individual panels, such that each panel may be replaced if any malfunction occurs. Each of the patterned OLED panels may be individually driven through an electrical connection within the fixture so as to be operated at substantially the same brightness and/or same chromaticity.
