Disclosed is a manufacturing method of a keypad for a mobile phone and the keypad manufactured thereby, in which a vacuum deposition layer and a cellophane paper are attached to a lower surface of a key in the keypad. The keypad for a mobile phone includes a plurality of keys, each key includes a key body of a transparent resin material and a high-hardness transparent coating layer coated onto a surface of the key body in order to increase hardness, and each key comprises a key background color paint layer for color presentation, coated onto a lower surface of the key body; an opaque paint layer coated onto a lower surface of the key background color paint layer; a transparent marking portion formed by performing a laser processing according to a shape of a numeral, a character, or a symbol with respect to the lower surface of the key body so as to remove the color paint layer and the opaque paint layer; a metallic vacuum deposition layer formed on the lower surface of the key body and a lower surface of the opaque paint layer; and a transparent color-printed layer or a cellophane paper attached to a lower surface of the metallic vacuum deposition layer so as to present various colors.

Provided are a wireless communication terminal having an external mike sensing function and its method that determine an operation state of a wireless communication terminal's own mike by sensing an operation of an external mike depending on whether or not a mike signal sensing is issued from the external mike. The inventive wireless communication terminal includes a connection unit for generating a predetermined state level value when an earphone is connected, and receiving a mike sensing signal from the earphone, a voice input unit, a voice output unit, and a control unit for controlling an operation of each of the voice input unit and the voice output unit based on the predetermined state level value and the mike sensing signal from the connection unit.

Disclosed is a two-way display-type liquid crystal display device. The device includes a pair of upper and lower display modules for displaying different information; a plurality of two-way light sources for simultaneously supplying predetermined amounts of light rays to the upper and lower display modules; a light guide panel separately located at a side of the two-way light sources in a manner such that the upper and lower display modules are positioned on upper and lower surfaces of the light guide panel, respectively, the light guide panel functioning to guide light rays radiated from the two-way light sources in two directions toward the upper and lower display modules; a scattering film interposed between the light guide panel and the lower display module, for scattering and reflecting the light rays radiated from the two-way light sources, toward the upper display module; and a reflective and transmissive sheet interposed between the light guide panel and the lower display module, for reflecting one part of the light rays radiated from the two-way light sources, toward the upper display module, and transmitting the other part of the light rays toward the lower display module.

Disclosed is a method for manufacturing an electronic device using LDS and an electronic manufacturing by the method, in which resin for LDS is adhered to an inner surface of an external case by double injection or insert injection so as to implement a circuit. The electronic device using LDS includes upper and lower external cases, wherein resin for LDS is adhered to an inner surface of the lower external case by double injection or insert injection. Components of the electronic device are mounted on the resin, and the upper and lower external case are assembled with each other.

Provided is a key for a portable terminal. The key includes a metallic case including a plated layer exposed to the outside of the portable terminal and an electro-forming layer formed on the inner side of the plated layer and a synthetic resin layer formed on the inner side of the electro-forming layer. The synthetic resin layer is formed on the inner side of the electro-forming layer by mounting the metallic case in a mold and performing insert injection. Since the key includes the electro-forming layer made of copper and the plated layer plated on the electro-forming layer on a surface for forming the exterior, it can be easily manufactured and can contribute to improvement of the exterior design of the portable terminal. Moreover, instead of plating the surface of the synthetic resin layer with nickel for forming the metallic case, the metallic case including the electro-forming layer made of copper and the plated layer is separately manufactured and insert injection is performed, thereby reducing the risk of causing allergy resulting from the use of nickel.
