KEY PAD AND KEY PAD ASSEMBLY

摘要

A keypad and a keypad assembly are provided to enable a user to press an accurate key by allowing the user to experience a pressing feeling of a key button region. A keypad includes an elastic layer(110) and an electron paper(130). The elastic layer provides a restoring force to the keypad. Plural key button regions are defined on the electronic paper which is arranged on the elastic layer. The key button regions provide various symbols in images. The keypad includes a buffer region(112) which is formed to correspond to respective key button regions between the elastic layer and the electronic paper on one portion in the elastic layer. The elastic layer includes plural bumps(111) which are protruded downwards from a position which is opposite to an upper surface of the electronic paper with which the elastic layer is contacted.
