Abstract: Improved manufacturing using a printer that deposits a liquid to fabricate a layer having specified thickness includes automated adjustment or print parameters based on ink or substrate characteristics which have been specifically measured or estimated. In one embodiment, ink spreading characteristics are used to select droplet size used to produce a particular layer, and/or to select a specific baseline volume/area or droplet density that is then scaled and/or adjusted to provide for layer homogeneity. In a second embodiment, expected per-droplet particulars are used to interleave droplets in order to carefully control melding of deposited droplets, and so assist with layer homogeneity. The liquid layer is then cured or baked to provide for a permanent structure.

Abstract: The present invention has an object to provide a planar light-emitting panel attached with a jacket to protect edges of a light-emitting tile, while the jacket is prevented from being peeled off or removed from the light-emitting tile. The planar light-emitting panel includes the light-emitting using a glass substrate as a base, and an elastic jacket covering end faces of the glass substrate. An emission surface is provided on a front face of the light-emitting tile. The elastic jacket has a rear face side opening, on a rear face side of the light-emitting tile. On opening edges of the rear face side opening, when viewed from rear, a plurality of jacket side protrusions protruding toward a center side of the rear face side opening are formed. The jacket side protrusions are separated at predetermined intervals along the opening edges.

Abstract: The invention relates to a substrate (2) for manufacturing an organic conversion device for converting electrical energy into light energy or light energy into electrical energy, wherein the substrate comprises a) an encapsulation layer (3) on the substrate, wherein the encapsulation layer includes a first inorganic layer (7), a second inorganic layer (9) and an intermediate organic layer (8), and b) a getter reservoir (6) in contact with the organic layer of the encapsulation layer. Water molecules will therefore not only be transported along the intermediate organic layer, but will also be gathered, especially absorbed, by the getter reservoir, if the encapsulation is damaged. This can slow down a transport of water molecules along a leakage path towards an organic conversion layer of the organic conversion device and hence slow down a possible degradation of the performance of the organic conversion device, if the encapsulation layer is damaged.
