A metal structure (1) has a display region being a second region and being integrate with another region being a first region which is a display region. The metal structure may constitute a monolithic structure of an information display unit, for example, a front panel of an electronic device. The display region is formed by providing a cluster of small non-through-going cavities (5) in the metal structure, leaving a very small thickness of material, the thickness being translucent (6). In addition to being a display unit when arranging a light source behind the translucent region (6), touch sensitive or non-touch sensitive input devices, optionally connected to acoustical input and registration devices, may also be provided. These input devices may advantageously be arranged in, or adjacent, the cavities in the metal structure, whereby when the front of the metal structure is viewed an indication of display or input options is visible.
