摘要:
A keypad module using light guide print and a method for manufacturing the same are provided to minimize a manufacturing cost by including only a light guide panel without an additional film between a keypad and a metal dome switch, a metal dome sheet, or a poly dome sheet. Light guide print layers(2a) are protrusively formed on positions in contact with a metal dome switch, a metal dome sheet, or poly dome sheets(3) of a lower end of a light guide panel(2). Color print layers(6) are formed on the light guide print layers and are printed with ink of various colors . The metal dome switch, the metal dome sheet, or the poly dome sheet are adhered and fixed to adhesion ink(7) by adhering and printing the adhesion ink to the color print layers. A keypad(1) is adhered and fixed to adhesion ink(7a) by adhering the adhesion ink to an upper end of the light guide panel. Light shielding ink(8) is attached to a peripheral circumference of a lower end of the light guide panel. A printed circuit board is adhered and fixed to adhesion ink(7b) by adhering the adhesion ink to the light shielding ink.
