1. An enclosure of a mobile terminal, comprising:
a substrate; and
a composite film layer coated onto the substrate, having a thickness changing along a first direction, a difference in thickness between any two regions arranged along the first direction of the composite film layer being less than or equal to 350 nanometers, the enclosure having a spatially varying color corresponding to a wavelength between 400 nanometers and 760 nanometers;
wherein the thickness of the composite film layer changes along a second direction, wherein the second direction is different from the first direction;
wherein an angle between the second direction and the first direction is less than or equal to 90°; and
wherein the thickness of the composite film layer increases in both the first direction and the second direction, or the thickness of the composite film layer decreases in both the first direction and the second direction.
