A smartphone case is no longer the only way to personalize your device as a company has come up with a way to infuse glass screen protectors with images and graphics that should completely disappear once a device’s screen is turned on.

Using a process the company calls “Phantom Printing,” Glassie has created a line of durable three-layer tempered glass screen protectors that are the first in the world that can be customized without, hopefully, hindering the use of the device they’re applied to. The screen protector’s middle layer can be personalized with text, illustrations, and even photos that have been converted into monochromatic patterns using a custom-developed infusing process, while the other two layers should provide durability against nicks, scratches, and cracks, as well as antimicrobial protection using a mixture of copper and silver ions that Glassie claims to kill up to 99.9 percent of germs and bacteria. That won’t kill COVID-19.

The company doesn’t share the exact details of how Phantom Printing works — presumably it’s a trade secret and it doesn’t want other companies replicating anytime soon.

At launch the Glassie screen protectors are only available for 11 iPhone models and pricing, at least for the versions with pre-made designs, is US$40.(SD-Agencies)
