FIG. 2 is a cross-sectional view taken along line II-II of the portable terminal of FIG. 1. As shown in FIG. 2, the keypad 102 is located inside the front cover 111 and the front cover 111 having the key region 102a described above, and emits different color light depending on the mode ( 140). Inside the front cover 111, there are at least two patterns corresponding to each mode, and filter units 131 and 132 are mounted so that only the patterns corresponding to each color light are visible in the key region 102a.

The front cover 111 includes a base cover 120 and a shielding layer 121 positioned outside the base cover 120 to at least partially cover the filter parts 131 and 132.

The base cover 120 may be formed of a synthetic resin-based light-transmitting material, and as described later, when the keypad 102 is a touch type, the base cover 120 may have a constant rigidity to support repetitive touch. It is desirable to be produced with a thick thickness.

The shielding layer 121 is positioned outside the printing layer 122 and the printing layer 122 that is formed in a partially transmissive shape on the outside of the base cover 120, and has a transparent protective layer 123 that protects the printing layer 122. ) The printing layer 122 may be implemented by printing an ink having an arbitrary color to cover the filter unit 131 132 or the light emitting unit 140 when no light is generated in the light emitting unit 140. .

As a possible implementation method, the transparent protective layer 123 may be in a form in which a transparent resin film is in-mold. That is, after the printed layer 122 is printed on the light-transmissive resin film, the printed light-transmissive resin film is integrally molded to the base cover 120. Thereby, the resin film turns into the translucent protective layer 123.

In another embodiment, the printed layer 122 is printed on a film, and the base is formed by transferring the printed layer 122 to the base cover 120 and then removing the film to form a base on which the printed layer 122 is formed. It is also possible to coat a transparent paint on the outside of the cover 120. A transparent paint can be performed by methods, such as vapor deposition. In this case, the transparent paint becomes the light transmissive protective layer 123.

The filter unit 131 and 132 selectively transmits light and filters out the rest by using an interference phenomenon of reflected light generated at the interface of the thin film. In addition to the thin film form, the filter units 131 and 132 may be embodied by making a fine and regular triangular prism rough surface having different angles on the surface to allow selective transmission according to color light.

2 illustrates a case in which the filter units 131 and 132 selectively transmit the light emitted from the light emitter 140. That is, the filter parts 131 and 132 include a first filter part 131 for transmitting only the first color light emitted from the light emitting part 140 and a second filter part 132 for transmitting only the second color light.

The first color light and the second color light can be set to blue light and red light, respectively. In this case, the first filter unit 131 may be formed to have a thickness that transmits only blue light and reflect or block red light, or may be roughened, and the second filter unit 132 may transmit only red light and transmit blue light. It is formed to a thickness or is roughed.

The light emitting unit 140 may have a form of low power consumption, such as a light emitting diode (LED), and collects a form that implements a multicolor or a form that implements a single color for different colors depending on a mode. Form is also possible.

A reflection layer 127 is formed inside the light guide layer 126 to reflect the light of the light guide layer 126 to the outside. The reflective layer 127 may be achieved by attaching a tape having an adhesive surface as a mirror surface or plating a metal on the light guide layer 126.

When the first color light is incident on the second filter part 132, the second filter part 132 blocks the first color light and is extinguished or reflected to continue. When the first color light is incident on the first filter part 131, the first color light is transmitted through the first filter part 131, and the user may recognize the light of the pattern of the first filter part 131. Therefore, the user can input keys set according to the first mode by a touch method (FIG. 3A).

When the portable terminal is in a second mode different from the first mode and the second color light is emitted from the light emitting unit 140, the second color light is extinguished or reflected by the first filter unit 131, but the second filter unit 132 By passing through, the user recognizes the light of the pattern of the second filter unit 132 (FIG. 3B).
