Samsung's next-generation displays are set to engulf and hide cameras completely
The Samsung Galaxy S10 series stands out among flagships as the only ones that avoid the notch by having their displays surround their front-facing cameras. However, these cameras are still visible as punch-holes through these screens. Their AMOLED panels have in fact been perforated using high-tech laser-cutting techniques to allow for this. Therefore, the front-facing modules are constantly visible through them.
This interruption to the otherwise full-screen S10 display may elicit responses ranging from indifference to distraction. However, it is less than completely necessary, Image sensors that can 'hide' under a display are technically possible; for example, they make up part of the optical fingerprint reader found in phones such as the OnePlus 6T. Then again, the technology to do the same for the Galaxy S10's screen must not be there yet.
Samsung's level of research into this matter may nearly be at this point, however. The Korean news outlet Yonhap News Agency reports that the company's vice president of Mobile Communication Display R&D Group, Yang Byung-duk, has stated that it is at least evaluating the possibility of a full-screen display that completely integrates and occludes components such as front-facing cameras.
However, the executive also admitted that this technology will not be available for at least 2 more years. Therefore, the S10 line's Infinity-O display may be a Samsung attribute for at least this long.
