1. A keyboard for a laptop computer, the keyboard comprising:
- a key comprising;
a keycap comprising an at least partially transparent material, the at least partially transparent material having a bottom surface;
a background ink layer disposed on the bottom surface of the at least partially transparent material and defining a glyph window having a side surface, the background ink layer comprising a bottom surface and a top surface; and
a glyph diffuser contacting the side surface of the glyph window between the top surface and the bottom surface of the background ink layer and having a bottom surface coplanar with the bottom surface of the background ink layer;
a substrate positioned below the key;
a switch positioned between the substrate and the key;
a support mechanism configured to support the key while the key is depressed by a user relative to the substrate.

Abstract
An illuminated glass keycap having a glyph diffuser layer that may diffuse light through a glyph window opened in a background layer. The background layer may be opaque and the glyph window may be transparent. The keycap is adhered to a scissor mechanism positioned above electrical switch circuitry. Included within, below, or adjacent to the scissor mechanism may be one or more light sources positioned to emit light through the keycap, around the perimeter of the keycap, and/or through the background layer.

11. A method of manufacturing a keycap, the method comprising:
-
depositing a background ink layer on a bottom surface of the keycap, the keycap comprising an at least partially transparent material; creating a glyph aperture through the background ink layer, the glyph aperture having a lateral width, wherein the keycap is at least partially exposed through the background ink layer; depositing a glyph diffuser material into the glyph aperture between a top surface of the background ink layer and a bottom surface of the background ink layer and filling the lateral width of the glyph aperture; planing the glyph diffuser material such that a bottom surface of the glyph diffuser material is coplanar with the bottom surface of the background ink layer. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A keycap for a keyboard of an electronic device, the keycap comprising:
-
a transparent body having a top surface and a bottom surface, the top surface being at least partially concave; a background layer formed on the bottom surface of the transparent body, the background layer defining a glyph shape; a diffuser layer configured to distribute light through the background layer or the glyph shape, the diffuser layer being positioned on an underside of the background layer and abutting sides of the glyph shape of the background layer, the diffuser layer being configured to link the background layer to a key support mechanism. - View Dependent Claims (19, 20)
