A three-dimensional sticker has an adhering layer removably attaching the three-dimensional sticker to an object. A filler material is positioned on an interior surface of the adhering layer, the filler material forming a three-dimensional configuration. A recording device is positioned on the interior surface of the adhering layer allowing the three-dimensional sticker to play a pre-recorded message and record a new message. A cover layer is positioned over the interior surface of the adhering layer enclosing the filler material and the recording device between the interior surface of the adhering layer and the cover layer.

The present invention discloses an optical film and a cover plate for an electronic device. The optical film comprises: a support; a micro/nano-structure layer which is formed by providing a groove on a surface of the support, which groove forms a micro/nano-structure and is provided with a filler; wherein the micro/nanostructure layer has a visual gradient in at least one direction. The present invention provides an optical film, which realizes a visual change or a gradient effect, by adjusting the area ratio of the micro/nano-structure, the depth of the groove, the period of the micro/nano-structure or the density of the micro/nano-structure, and produces a decorative or practical effect. It plays an aesthetic role when used in the casing of an electronic device, and it can shade light but not block the sight line when used in buildings or automotive glass. Furthermore, no black spots will appear with this structure, and it is visually more artistic.

An optical illusion device and method of production is described. The method comprises producing a digital sculpt. A rendered visual image and a thinned digital sculpt are then produced from the digital sculpt. Next a digital thickness shell is produced from the thinned digital sculpt. Finally, the rendered visual image is employed to impart a lithophane depth map onto the digital thickness shell. The overall result is an optical illusion device comprising a negative image forming surface with a registered lithophane image imparted on thereon. When the optical illusion device is viewed from various angles (and with a light source placed behind it), the negative image forming surface appears to the viewer as a positive or convex model with a photographic image applied to the profiled surface. The illusion created is of a panning, three-dimensional photographic image, complete with improved detail due to the presence of the lithophane depth map.

A decorative sheet is caused to emit light from part of the front surface to improve the design features. A decorative sheet 1 according to an embodiment includes a first refractive index layer (high refractive index layer) 11 having a first refractive index, a decorative layer 14, a second refractive index layer (low refractive index resin layer) 12 that has a second refractive index lower than the first refractive index and is provided between the first refractive index layer and the decorative layer, and a light diffusion layer 15 that is provided in partial contact with one surface of the first refractive index layer and diffuses light entering from the first refractive index layer so that light is released from part of the front surface of the decorative sheet. A resin molded body 21 may be integrally laminated on the back surface side of the decorative sheet 1 to form a decorative molded article 2. In addition, the decorative molded article 2 may be provided with a light source 31 that injects light from the side surface of the decorative sheet 1 to form a decorative module 3.

The present disclosure relates to ornamental indicia carrier and method of producing the same. In some embodiments, the ornamental indicia carrier comprises an ultraviolet light (UV) cured ink printed on a thin flexible film and combined with an adhesive layer. The ornamental indicia carrier is capable of enduring the conditions inside the mouth for an extended period of time and can be used in conjunction with a dental appliance.

A display panel includes a base material that transmits light, a groove portion defined in a back surface of the base material and defined corresponding to a display pattern that is displayed on a front surface side of the base material, a light-blocking film, formed on the back surface where the groove portion is not defined and on a side surface of the groove portion, that blocks light through the back surface, a light-transmissive region that includes a region on an upper surface of the groove portion where the light-blocking film is not formed and that transmits light, and a metal film formed in at least the light-transmissive region.

A partially perforated assembly includes a perforated film layer, a perforated adhesive layer applied to one side of said film layer, a non-perforated overlaminate film layer on the other side of said perforated film layer, and a release liner on the side of said perforated adhesive layer remote from said perforated film layer. When the release liner is removed and the remaining layers of the assembly are applied to a substrate, the remaining layers of the assembly comprise a void network. The void network fluidly interconnects at least two discrete perforation holes in the perforated film and adhesive layers with each other and/or the ambient environment around the assembly so as to facilitate air communication among the holes and/or between the holes and the ambient environment.
