Black foil on OLED display damaged
As my top glass on the Apple Watch 3 broke, I ordered a new digitizer. When I removed the glass from the display, I damaged a black foil on the OLED display at the edges. The display is still working, but there are bright areas, where the foil is missing. What kind of foil is on the display? Can I replace it? Where to buy?
The display looks like this now (glass removed, dark foil damaged):
