1. A composite membrane, comprising:
a carrier layer; and
an information layer, wherein the information layer is disposed on one side of the carrier layer along a thickness direction of the composite membrane, and the information layer further comprises a light-transmitting layer, a first pattern layer, and a second pattern layer, which are disposed along the thickness direction of the composite membrane, wherein:
the first pattern layer is disposed close to the carrier layer;
the light-transmitting layer is disposed on one side of the first pattern layer facing away from the carrier layer; and
the second pattern layer is disposed on the other side of the light-transmitting layer facing away from the carrier layer, and the second pattern layer and the first pattern layer present different visual information of one multi-dimensional object, wherein the first pattern layer has a first thickness, the second pattern layer has a second thickness, and the first thickness and the second thickness are in a same pre-defined range such that the release layer, the first pattern layer, the light-transmitting layer, and the second pattern layer bind together;
a light-transmitting metal layer disposed on one side of the second pattern layer, wherein the second pattern layer is sandwiched between the light-transmitting metal layer and the light-transmitting layer, and the light-transmitting metal layer permits light to pass through; and
a light-transmitting protection layer disposed on one side of the light-transmitting metal layer facing away from the carrier layer.
