Abstract

This creation is an optical structure with a three-dimensional effect. It mainly forms prism surfaces composed of continuous concave and convex surfaces in the longitudinal and transverse directions on the surface of the optical substrate (molding methods include injection molding, roll molding, etc.), and then uses spray printing to The machine sprays the preset image layer on the prism surface of the optical structure to form an optical structure that makes the image layer present a three-dimensional effect when viewed from the reverse side. Since the size and depth range of the convex and concave peaks and valleys on the prism surface is between 20 and 80μ, the pigment of the printed image layer only covers the convex peaks and fails to penetrate into the concave valleys. The valley is transparent because there is no pigment; when light is incident from the reverse side of the optical structure, through multi-angle reflection and refraction, the image layer presents a three-dimensional visual change effect.

Description

Optical structure with stereoscopic effect

This invention is an optical structure with stereoscopic effects that is widely used in electronic products, especially one that is integrated and can show optical visual changes.

Existing flat prints include 2D images and 3D images. The printing technology of 2D images is quite mature, but the visual effect is limited to 2D effects and has certain limitations. Existing 3D image prints generally use a concave-convex film to produce the 3D effect, which is not only rough but also produces unsatisfactory visual effects. It can easily give people a dazzling, soft or even dizzy feeling.

In recent years, young people are pursuing the form of protective cases for mobile phones, requiring dazzling appearance, cool shapes, and novel patterns. Therefore, manufacturers of mobile phone related spare parts use this as a starting point to conduct research and development designs on mobile phone cases. Generally speaking, It is said that the most common one is to directly print various 2D image layers (3) on the outer surface of the mobile phone case (4), as shown in the first picture; a small number of better quality ones will print the pattern printing layer on the surface. It is then covered with a protective transparent film, and furthermore, the image layer (3) is printed on a plastic injection mold of the plastic plate body to be integrally formed.

Although the above-mentioned methods can form images on the surface of the mobile phone case, they only simply present the visual effect of 2D images. Apart from adding a little more variety to the bland mobile phone case, they have no distinctive features, and it is more difficult to create an eye-catching effect. Amazing results. Furthermore, when the image layer is printed directly on the outer side of the mobile phone case, it is often easy to cause the image to become damaged due to accidental collisions, drops, scratches and other factors after use. The image layer is scratched, peeled off, faded, etc., prompting the phone case to be replaced or discarded.

The creator of this project felt that the visual effect of directly printing a 2D image layer on the surface of the substrate was not obvious, so he conducted in-depth research and applied it based on his own experience, and proposed an optical structure with a three-dimensional effect, which he hopes will bring benefits. society at large.

The main purpose of this creation is to provide an optical structure with a three-dimensional effect. By forming an optical structure with concave and convex prism surfaces through injection molding, the image layer is spray-printed on the prism surface of the optical structure and the pigment does not Completely covered, through the reflection and refraction when light enters, the opposite side of the prism surface of the optical structure presents a visual effect that enhances the image.

In order to achieve the above-mentioned projects, the creator of this project designed an optical structure with a three-dimensional effect.

In a preferred embodiment, the prism surface is composed of a plurality of parallel and equidistant transverse curved V-shaped grooves, which are staggered with a plurality of parallel and equidistant longitudinal V-shaped grooves.

In one embodiment, the depth range of the longitudinal and transverse V-shaped grooves on the prism surface is between 20 and 80 μ, and is preferably below 50 μ.

In one embodiment, the inverted V-shaped angle range of the prism surface convex part is between 90~140 degrees.

In a preferred embodiment, the optical structure with prism surfaces can be used as a transparent structure of a photo frame.
