Apparatus and method for performing a mirror function in a portable terminal |
摘要 |
<p>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. <IMAGE></p> |
