The present invention provides a method for emulating a multilayered frame using an OLED, in which the body of the OLED is cut into a plurality of flame sheets stacked on each other and isolated from each other. The body and the flame sheets are fabricated into the same shape as the flame shape of a real fire. Each of the flame sheets is electrically connected to a controller via a conductive wire. The brightness of each flame sheet is controlled by a controller to emulate a multi-layered shape of flame. The resulting shape of flame is similar to a flame shape of a burning real fire, thereby providing a vivid emulation effect that can desirably decorate the environment and heighten the atmosphere. The present invention also provides an OLED manufactured with such a method.
