Abstract: The present disclosure describes optical and optoelectronic assemblies that, in some cases, include screen-printed micro-spacers, as well as methods for manufacturing such assemblies and modules. For example, micro-spacers can be applied on a first optical element layer, and a second optical element layer can be provided on the first micro-spacers. By providing the second optical element layer on the first micro-spacers, the second optical element layer and the first optical element layer can be separated from one another by air or vacuum gaps each of which is laterally surrounded by a portion of the first micro-spacers.
