Abstract
A keycap includes a keycap main body and multiple metal oxides. The metal oxides are doped in the keycap main body and forms an opaque region and a light-transmitting region in the keycap main body. The light-transmitting region is formed by irradiating a portion of the opaque region with an energy beam. A transmittancy of the light-transmitting region is greater than a transmittancy of the opaque region. A manufacturing method of the keycap is also disclosed.
Claims24
A keycap, comprising:
- a keycap main body;
- and
- a plurality of metal oxides, wherein the metal oxides are doped in the keycap main body and forms an opaque region and a light-transmitting region in the keycap main body, the light-transmitting region is formed by irradiating a portion of the opaque region with an energy beam, and a transmittancy of the light-transmitting region is greater than a transmittancy of the opaque region.
A keycap, comprising:
- a keycap main body;
- a plurality of metal oxides;
- and
- a character layer disposed on an outer surface of the keycap main body, wherein the metal oxides are doped in the character layer, the character layer comprises an opaque region and a light-transmitting region, the light-transmitting region is formed by irradiating a portion of the opaque region with an energy beam, and a transmittancy of the light-transmitting region is greater than a transmittancy of the opaque region, and a shape of the light-transmitting region is a character or a graphic.
