Why Phone Screens Still Have Bezels: The Engineering Reality

What Happened A Reddit user in the r/explainlikeimfive community asked why electronic displays still need bezels despite ongoing efforts to minimize them. This reflects a broader consumer observation about the smartphone industry’s “bezel-less” marketing claims versus physical reality. While manufacturers like Apple, Samsung, and others have dramatically reduced bezel sizes over the past decade, completely eliminating them remains technically challenging. Even the most advanced “edge-to-edge” displays retain thin borders, particularly at the bottom where home indicators appear.
