摘要： A light-transmissible keycap and the manufacturing method thereof are provided. The light-transmissible keycap has multiple light-transmissible symbol areas, and each light-transmissible symbol area has at least one character assigned with a color. Each light-transmissible symbol area is covered with only one light-transmissible color layer. Thus, when an external light is emitted from a light source beneath the keycap, the external light will only pass through one light-transmissible color layer covering that light-transmissible symbol area, and not pass through the light-transmissible color layer covering the other light-transmissible symbol area. Therefore, a bleeding problem due to multiple light-transmissible color layers overlapped and covering the same light-transmissible symbol area is avoided.

摘要： A transparent keycap manufacturing method includes adhering an opaque base to a fixing film, performing a laser engraving process or an etching process on a bottom surface of the opaque base to generate a continuous hollow pattern region and a pattern component surrounded by the continuous hollow pattern region, coating transparent glue on the bottom surface of the opaque base to fill the continuous hollow pattern region with the transparent glue, adhering a transparent base to the bottom surface of the opaque base, and removing the fixing film from the opaque base.

摘要： A method of manufacturing keycaps, each keycap having a top and a skirt, includes: providing a first jig having a plurality of positioning units; arranging correspondingly a plurality of keycaps onto the plurality of positioning units; attaching a first film including an ink layer and a first release layer to the plurality of keycaps by using an out-mold transfer technique, such that the first film covers respective upper surfaces of the tops and respective side surfaces of the skirts of keycaps; removing the first release film; laser-engraving the ink layer; and forming a protection layer on the laser-engraved ink layer. A keycap manufactured by the method of the present invention is also disclosed.

摘要翻译： 提供了一种光传输键帽及其制造方法。 光传输键帽具有多个透光符号区域，并且每个光透射符号区域具有至少一个颜色分配的字符。 每个透光符号区域只覆盖一个透光色层。 因此，当从键帽下方的光源发射外部光时，外部光将仅穿过覆盖该透光符号区域的一个透光性色层，并且不穿过覆盖另一个的透光色层 光传输符号区域。 因此，避免了由于多个透光的彩色层重叠并覆盖相同的光透射符号区域的渗色问题。
