Apparatus and method for performing a mirror function in a portable terminal
First Claim
1. A method for performing a mirror function in a portable terminal which includes a Liquid Crystal Display (LCD), comprising the steps of:
- determining if there is a key input from a user while the LCD performs a common display function;
if there is a key input, determining if the key input corresponds to a mirror function on;
if the key input corresponds to the mirror function on, powering off the LCD;
determining if there is a key input or call receipt from the user corresponding to a mirror function off condition while the LCD performs as a mirror; and
if the key input or call receipt is performed, powering on the LCD, whereby the LCD returns to said common display function,wherein the LCD operates as a mirror when no power is applied to the LCD, and as a common display unit when power is applied to the LCD.

Abstract
Disclosed is an apparatus and method for embodying mirror function in a portable terminal by which a user can use an LCD of the portable terminal as a mirror, with a rear polarizer of the LCD constructed to allow the LCD to reflect incident light and to perform as a mirror when powered off, and to perform the original function of LCD when powered on. The LCD may further comprise a front polarizer for polarizing the external incident light to a certain direction, a liquid crystal for deflecting the incident light from the front polarizer about a molecular axis in the liquid crystal and arraying the light parallel to the direction of an electric field to pass the light along the molecular axis, and a rear polarizer for reflecting incident light from the liquid crystal when power is not applied and allowing the incident light to pass by the liquid crystal when power is applied.
