Bezel

The bezel is the frame around the edge of the screen. It holds the front of the panel stack in place, protects its fragile edges and gives the TV its finished look. Modern TVs have made it very thin, often just a few millimeters, so the picture seems to float.

On this TV it is made of aluminum alloy by extrusion. A billet of the alloy is heated to around 450 to 500 °C, soft but not melted, and a huge ram pushes it through a steel die with an opening shaped like the frame's cross-section. A long bar with that exact profile slides out. It is cooled, stretched straight, aged in an oven to reach full strength and cut into four sides with angled ends. The surface is brushed or blasted, then anodized, which grows a hard, colored oxide skin, or painted. The four pieces are joined at the corners and fitted around the panel.

In the television, the bezel clips or screws to the frame behind it. Many budget TVs use a molded plastic bezel instead, and some designs have almost no bezel at all, with the panel's own edge forming the border.
