However, the solution adopted here is flat, and simply covers the rounded edges without sticking it or follow its contours.
Two problems then with this solution:
1. / dust is dramatically accumulates under the "black" parts (not glued, so)
2. / black parts are very fragile, since there is an "empty" below (rounded parts of the screen) and thus a cantilever.
I had shards of glass on the side after less than a week of use. However splinters have not scratched my screen because the glass has a plastic layer on the side in contact with the screen.
So good product for a fair bit design for my taste.
To find a similar solution with a silicone filler (or other) between the glass and the rounded parts!
