KEYBOARD DESIGN

摘要

Embodiments of a backlit keyboard assembly are described. A keycap (202) assembly is mounted into a case web (104) having intersecting ribs. A flange (210), which can be angled, is on the bottom perimeter of the keycap (202) and a correspondingly shaped flange (212) is on each rib of the case web (104). An overlap of the keycap flange (210) and the case web flanges (212) prevents direct sighting of the backlight light source (208) and also provides a more evenly distributed halo around the keycap (202), thereby improving both aesthetics and functionality by providing better light control and contrast.
