Definition - What does Bezel mean?
Bezel is a term used to describe the outside frame of a computer, monitor or any other computing device. This is important for product developers and designers in evaluating the overall perimeter of the device/component and its possible ramifications. Newer device designs such the iPad have extremely narrow bezels, allowing for more screen. This has become an increasingly important design factor for consumers.
Techopedia explains Bezel
Electronics such as tablet computers and smartphones are increasingly moving toward a bezel-less design. The bezel serves to hold the screen in place, and perhaps also reduce unintentional inputs on a touch screen. However, newer designs are increasingly reducing the need for the former, while the latter problem can often be solved with software. For example, when the iPad mini was introduced, its thin bezel led Apple to adapt its software to ignore inputs in which a user is simply resting a finger on the screen.
