Abstract
A method of embedding a screen in a substrate includes placing the screen on the substrate, and then melting part of the substrate, so that the screen becomes embedded in the substrate. The melting may involve heating at least part of the screen to melt part of the substrate, or directly heating the part of the substrate. The screen may be a screen of electrically-conductive material, and the heating may be Joule heating in which an electrical current is passed through the screen to heat the screen. Alternatively, the heating may involve microwave, conductive, or laser heating. The produced device of the substrate with an embedded screen may be an optical window with an embedded electromagnetic interference (EMI) screen, may be a touch screen or touch display, or may be a window with an embedded heating element, to give a few non-limiting examples.
