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.

Abstract: A method of manufacturing a light guide plate containing a plurality of light-guiding micro structures comprises the steps of: preparing a mold that has a concave hole formed by a plurality of light-guiding micro structures; pouring a mixture of ultraviolet curable resins and glass microbeads into the mold; attaching a carrier onto the mixture; using a rolling tool to roll the surface of the carrier, such that the mold is filled up with the mixture uniformly, while the air among the mold, the carrier and the mixture is discharged; and finally projecting the ultraviolet light onto the ultraviolet curable resin, such that the ultraviolet curable resin can be cured at the carrier and removed from the mold, so as to form a light guide plate having a plurality of light-guiding micro structures.

Abstract: A keypad assembly having three-dimensional patterns includes a bottom layer, a light-guiding plate, a pattern layer, a coating layer and a surface layer. The light-guiding plate is overlapped on the bottom layer. The pattern layer is provided on the light-guiding plate. A plurality of three-dimensional patterns is provided on the pattern layer. The coating layer is coated on the upper surface of the pattern layer. The surface layer is overlapped on the coating layer. The surface layer is formed with a plurality of keycaps to correspond to the three-dimensional patterns. Via the above arrangement, patterns such as characters, symbols or icons can be displayed in the keycaps in a three-dimensional manner, thereby increasing recognition and visual effect.

Abstract: In a method for manufacturing keypad having three-dimensional patterns, curable resin is filled in a mold, and a ultra-violet lamp irradiates the curable resin, thereby curing the resin. A plurality of different materials is overlapped with each other, and a coating layer is coated on the surface of each three-dimensional pattern, thereby manufacturing a key having three-dimensional patterns. Via the above arrangement, the recognition and aesthetic feeling of each three-dimensional pattern can be increased.
