Abstract
Embodiments are directed to a keyboard or other input structure having a diaphragm that controls the illumination of a perimeter of a keycap. In one aspect, the keyboard includes a dome configured to buckle in response to a depression of a keycap. A support structure may support the keycap above the dome. A light source may be positioned below the keycap and configured to illuminate one or more illuminable symbols defined on a top surface. A diaphragm may be positioned above the light source and have a barrier portion extending from a perimeter of the keycap. The barrier portion may be configured to control illumination of the perimeter of the light source, including substantially preventing the illumination of the perimeter in order to mask or conceal an illuminated halo around the keycap.
