Panel

A panel is a flat surface, typically rectangular or curved, that forms part of a larger device, structure, or system. Panels can serve as coverings, partitions, or interaction surfaces. The word also refers to a group of people convened to discuss or decide on a topic, such as a panel of experts.

In engineering and manufacturing, panels are used as protective enclosures, diagnostic access doors, or decorative facades. They are made from metal, wood, plastic, glass, or composites. Common examples include instrument panels in vehicles and aircraft, control panels for electrical equipment, and solar panels that contain photovoltaic cells.

In display technology, display panels present information to the user, including LCD, LED, and OLED panels used in monitors, televisions, and mobile devices.

In architecture and interior design, paneling covers walls, ceilings, or furniture with arranged panels for aesthetics or acoustics.

In art, a panel is a painting prepared on a wooden surface, a traditional support for medieval and early Renaissance works.

In media and events, a panel refers to a group of experts who discuss topics in front of an audience; a panel discussion organizes their commentary and responses.
