发明名称 Method of manufacturing a keypad structure having a transparent keycap and keypad structure having a transparent keycap
摘要 The present invention discloses a method of manufacturing a keypad structure having a transparent keycap and a keypad structure having a transparent keycap. A metal pattern layer is formed on a transparent resin layer of a keycap component. Two print layers are formed on a transparent resin layer of an overprint component. Two print layers and the metal pattern layer are overlapped and have a level difference in height of the total thickness of the two transparent layers. Accordingly, the figure of the keypad seems to be floated and is felt to be three-dimensional.
