Abstract
A keycap and a method of manufacturing the same are disclosed. The method is to injection-mold a cap with a layer structure of ink thereon by an in-mold transfer method; then, to form a pattern on the layer structure of ink by a high energy optical engraving method; and at last, to form a light-permeable protection layer on the layer structure of ink to cover the pattern. The keycap according to the invention is therefore obtained. Therefore, the invention can reduce the manufacturing time relatively to a conventional keycap with a pattern formed thereon, such as a keycap for backlight keyboard. Furthermore, the invention can improve the binding strength between the layer structure of ink and the cap by use of the in-mold transfer method.
