The bezel is the physical frame or border surrounding the active area of a display. It serves protective and structural functions: it shields the panel edges from mechanical damage and environmental ingress (moisture, dust) and provides a mounting surface for the screen within the device enclosure. Bezels may be made of plastic, metal, or glass and can range from thick, prominent edges to very thin or nearly invisible borders.
In industrial screens, wider bezels are often used to reinforce the structure or integrate sealing gaskets, while consumer devices tend to minimize bezel width to maximize the visible area for a given overall footprint. The term “bezel” can also refer to decorative trim elements around the screen, such as printed designs or finished edges.
