Keyboard design

摘要

Embodiments of a backlit keyboard assembly are described. A keycap assembly is mounted into a case web having intersecting ribs. A flange, which can be angled, is on the bottom perimeter of the keycap and a correspondingly shaped flange is on each rib of the case web. An overlap of the keycap flange and the case web flanges prevents direct sighting of the backlight light source and also provides a more evenly distributed halo around the keycap, thereby improving both aesthetics and functionality by providing better light control and contrast.

1. An illuminated key positioned within an aperture having a flanged aperture perimeter, the illuminated key comprising:
a keycap positioned within the aperture and comprising a keycap flange having a geometry corresponding to that of the flanged aperture perimeter, the keycap flange extending from a perimeter of a bottom of the keycap; and a backlight positioned below the keycap and oriented to transmit light toward the keycap; wherein the keycap flange at least partially blocks light from the backlight from exiting the aperture.
