Abstract
Apparatuses and methods for forming holes or recessed regions in a substrate or a web material used in displays is disclosed. One embodiment of the invention relates to a roller or template that creates recessed regions or holes by pressing protruding structures from a template or roller in the substrate while the substrate is moving through a web process. These recessed regions or holes in the substrate receive, in one embodiment, elements that have integrated circuits thereon. Another embodiment shows recessed regions or holes being created in a web material by a template or a roller while the web material is moving through a web process. Another embodiment of the invention includes using a web wheel to create recessed regions or holes in the substrate. Another embodiment includes using chemical etching to create recessed regions or holes in the web material.
