Abstract
A key structure is disclosed in which the use of space for a keypad is maximized, thereby allowing free key inputs. The key structure includes a first keypad layer converted into a transparent state and a semi-transparent state, for displaying characters and numbers printed on the first keypad layer when the first keypad layer is in the semi-transparent state while displaying characters and numbers printed on a second keypad layer when the first keypad layer is in the transparent state. The key structure further includes the second keypad layer displaying characters and numbers printed on the second keypad layer by using light emitted from a light source when the first keypad layer is in the transparent state, and the light source emitting light to the second keypad layer when the first keypad layer is in the transparent state.
