ABSTRACT:
A keypad having three-dimensional patterns and a method for manufacturing the same. The keypad includes a base layer, a light-guiding plate, a pattern layer, a shielding layer and a keycap layer. The light-guiding plate is overlapped on the base layer. The pattern layer is provided on the light-guiding plate. A plurality of three-dimensional patterns is provided on the front surface of the pattern layer. The shielding layer is coated on the back surface of the pattern layer, and is formed with a plurality of hollowed regions to correspond to the three-dimensional patterns. The keycap layer is overlapped on the pattern layer and formed with a plurality of keycaps to correspond to the three-dimensional patterns. In addition, the present invention provides a method for manufacturing keypad having three-dimensional patterns. Via the above arrangement, the recognition and aesthetic feeling of each three-dimensional pattern can be increased.
