Graphic overlay is a decorative and functional element displaying graphical information at all times – even when the device is switched off. It can be a current keyboard cover, info or brand label, a scale, or a measuring-tape, as well as a barrier shielding the device against dust, moisture, chemicals, and mechanical impact. The simplest graphic overlay is a graphic, self-adhesive plastic layer, but it can be supplemented with various technical elements, relief, windows. Thanks to its high mechanical durability and excellent optical clarity, this is a very popular solution.
