There are plenty of "unbreakable" coatings. It sounds like what makes this unique is that is was suitable as a display cover. An initial evaluation would be measuring things like how much light energy of what frequencies is able to penetrate the coating. Is the viewing angle acceptable for a consumer device, etc. Hitting it with a hammer can always come later when they determine that it is a good display glass first.
