Unearthed by LetsGoDigital, most of the design sketches depict a phone with a hole in the display that will house the selfie camera which differ in the way their corners are rounded. Given that the Galaxy S10 is heavily rumored to employ exactly such a design (Samsung calls it Infinity-O), these might be the approaches Samsung will take with the various S10 models' designs.
The fun part is that on most of these images, the hole-in-display camera is placed at the left, except on the J-L schematics which are said to be of a separate design patent filing. How will Samsung manage to pierce through the OLED display and still show uninterrupted imagery around the Hole In Active Area (HIAA) concept?
Korean media is reporting that it will be employing laser drilling between the OLED deposition and thin-film encapsulation (TFE) processes. The process is more challening to do with Samsung's flexible OLED displays that use plastic instead of glass substrate, as the hole's circumference has to be sealed separately against oxygen and moisture to prevent LED deterioration.
Still, if anyone could do it easily, Samsung wouldn't be unique in employing it on its signature flexible OLED screens, and the Galaxy S10 is an anniversary edition of the famed S-line that needs to be unique.
