Transparent keycaps
Keycaps for keyboards that have transparent top portions have a set of layered components to define a top surface that provides key definition by curvature, texture, ridges, or other external structural features. Other portions of the keycaps define a glyph or support structure for the top layer. Features such as angle filters and partially reflective materials are implemented to improve the visibility, contrast, and reflectivity of the keycaps. Multiple methods are used to bend or otherwise modify rigid transparent materials such as glass in order to add surface features and to improve aesthetics of the keycaps of a keyboard.
1. A keycap for a keyboard, the keycap comprising:
a key body comprising:
a transparent body having a bottom surface;
a partially mirrored material positioned under the bottom surface of the transparent body;
a lower layer positioned under and contacting the partially mirrored material, the lower layer having a first section defining a boundary and a second section within the boundary, the partially mirrored material overlapping the boundary, the first section comprising a first opaque or translucent material, the second section comprising a second opaque or translucent material, the first opaque or translucent material and the second opaque or translucent material each having different color properties; and
a carrier body configured to support the transparent body and the partially mirrored material.
2. The keycap of claim 1 , wherein the partially mirrored material includes a third section defining a glyph boundary and a fourth section surrounding the glyph boundary.
3. A keycap for a keyboard, the keycap comprising:
a key body comprising:
a transparent body having a bottom surface;
a partially mirrored material positioned under the bottom surface of the transparent body, the partially mirrored material having a first section defining a first glyph boundary and a second section surrounding the first glyph boundary, the first and second sections having different visual characteristics;
an opaque layer positioned under and contacting the partially mirrored material, the opaque layer having a third section forming a second glyph boundary and a fourth section surrounding the second glyph boundary, the third and fourth sections having different visual characteristics, the first section of the partially mirrored material overlapping the third section of the opaque layer; and
a carrier body configured to support the transparent body and the partially mirrored material.
4. The keycap of claim 3 , wherein the key body further comprises an opaque material positioned under the bottom surface of the transparent body, the opaque material having a glyph aperture bounded by the second glyph boundary, the partially mirrored material covering the glyph aperture, wherein the carrier body, the partially mirrored material, and the transparent body are configured to pass light from a light source below the carrier body through the carrier body, the partially mirrored material, and the transparent body.
5. The keycap of claim 3 , wherein the partially mirrored material is an angle filter.
6. The keycap of claim 3 , wherein the transparent body comprises a top surface having edges and a center, the edges being raised relative to the center.
7. The keycap of claim 3 , wherein the second glyph boundary defines an outer area of a glyph of the key body and the first glyph boundary defines an inner area of the glyph.
8. The keycap of claim 3 , wherein an aperture is formed within the second glyph boundary, the aperture being filled with a translucent material.
9. The keycap of claim 3 , wherein a non-mirrored material is positioned in the first section of the partially mirrored material.
