The coverlens – also known as a cover glass or front glass – protects the display from scratches, dirt and UV radiation. The cover lens is bonded to the display.

You can adjust many things with a cover lens. Most important are the size and thickness of the glass. But the hardness also plays a role, because no one likes to have scratches on the display. The edges of the Cover Lens glass can be rounded or angled and, if necessary, a privacy screen can be printed around the display. There are different coatings for the surface. The most common are anti-glare and anti-fingerprint coatings.

To adhere the display to the cover lens – also called “bonding” – there are two different ways. The first is air-gap bonding (cheaper). This involves applying an adhesive such as a DST to the edge of the screen and then pressing the cover lens onto it. The second variant is optical bonding (more expensive). Here, the transparent liquid adhesive is spread over the entire screen and then pressed together with the cover lens. The advantages of this are a more robust bond and no impairment of the image due to an air gap (causes reflections).
