Description

Optical flat

technical field

This case belongs to the field of optical products, especially about an optical plate structure with at least two optical microstructures completed in one process.

Background technique

Generally, it is commonly used for optical microstructures on stationery such as cards, backing boards or book covers, such as Lenticular or Fresnel Lens. Among them, the grating plate is a transparent sheet composed of many slender straight plano-convex lenses (Plano-Convex Lens) arranged side by side. Since each plano-convex lens can partially enlarge the image under the grating plate, when When the angle of the eyes watching the image changes, different positions of the image will be partially enlarged with the angle of sight, so different patterns will be presented at different viewing angles, resulting in such as: changing circle (Flips), animation (Motion ) or 3D stereoscopic and other optical effects. Since the plano-convex lenses on the grating plate are equidistantly arranged side by side, the plano-convex lenses are formed by rolling a roller-shaped mold on the surface of a material during the manufacturing process.

However, this Fresnel lens is an optical microstructure of a planar lens, which has the property of converging light and can be used as a magnifying glass. With the advancement of plastic material technology, this Fresnel lens is also made into a low-cost A magnifying glass that can be easily carried around in the shape of an ultra-thin business card. The Fresnel lens uses a mold to press one side of the plastic material to record a plurality of refraction structures arranged in concentric circles, and the other side is a smooth plane. Furthermore, the angle and thickness of each ring of refraction structures are different, which is basically equivalent to the plano-convex lens in traditional optical elements, so it can use the interference and diffraction of light to focus the light beam on one point. Generally, it can be used in spotlights, projectors, car headlights, infrared human body sensors, small magnifying glasses, various bookmarks, automatic door sensors, forehead temperature guns, infrared thermometers, LED lighting, etc.

However, the manufacturing process (rolling) of the above-mentioned grating plate and the manufacturing process (pressing) of the Fresnel lens belong to two completely different types of manufacturing processes. There is a certain degree of difficulty.

Or, as in the Taiwan Province of China New Patent No. M263232 "Card with Lens Function", please refer to Figure 1, which is a schematic structural diagram of the existing patent case.

This method of embedding and fixing the lens 10 can also be expanded and applied to the combination of two different lenses. Usually, there is a problem of strength, so an adhesive is used to bond between the card and the lens or between the lens and the lens. , but it is also very easy to cause the lens to fall off due to improper external force.

Therefore, the inventor provides an optical plate structure, which uses a process to simultaneously manufacture a light-transmitting plate body with at least two optical effects, and the light-transmitting plate body has a first optical microstructure and a first optical microstructure adjacent to each other.

Furthermore, one of the optical microstructures also has a flat surface to form a three-dimensional image with the subsequent and patterned layers, which is quite suitable for the customization process.
