Abstract: An imaging device with micro-scale optical structures comprises a plurality of display units, where each display unit comprises a plurality of micro-scale optical structures, and each micro-scale optical structure comprises a convex part, a planar part, and base part. The convex part is positioned on the base part and has an arc surface, where the arc surface comprises a left side arc face and a right side arc face for reflecting oblique incident lights from the left or the right to form a reflected light toward the front. And different arrangements of micro-scale optical structures are used for reflecting left side and right side incident lights to display different characters or images.

Abstract: A method of fabricating a plastic part having a three-dimensional image and visual effect. A plastic part having a three-dimensional graphical surface and a flat plane is formed. Subsequently, a thin film layer is formed on the plastic part to provide three-dimensional image and visual effect to the plastic part, where the three-dimensional graphical surface provides the three-dimensional image and the thin film layer provides the visual effect.
