KEYPAD HAVING LIGHT GUIDE LAYER AND KEYPAD ASSEMBLY

摘要

A keypad having light conductive layer and a keypad assembly are provided to reduce a number of required light emitting elements and power consumption by mounting the light conductive layer. In a keypad, a light penetrates through an inside of a light conductive layer(220). At least one key button(270) is formed at an upper side of the light conductive layer(220). A lower elastic layer(240) is attached to a lower side of the light conductive layer(220) in an opposite region to the upper side. A reflective pattern(250) formed at the lower side of the light conductive layer(220) reflects a part of light traveling toward the inside of the light conductive layer(220) to the key button(270).
