Identification device

Abstract

The invention provides an identification device, which includes: a carrier and a plurality of pixel-like. The plurality of pixel-like pixels are formed on the carrier, and the pixel-like pixels further include at least one grating, the grating has a plurality of grating structures formed on the carrier, and the distance between the grating structure and the grating structure is between 50nm and 900nm. Through the identification device, specific images and specific colors can be presented at specific angles, which can be recognized by the naked eye. When the specific angle is deviated from, the specific images and specific colors cannot be recognized, so an excellent recognition effect can be achieved.

Description

technical field [0001] The present invention relates to an identification device, in particular to a method that utilizes a grating with a color rendering effect to form a type of pixel through at least one type of grating, and then forms a specific image through a plurality of similar pixels to form a specific image. A recognition device that presents a specific image and a specific color at an angle to achieve an excellent recognition effect. Background technique [0002] For the high-tech industry or boutique market, its noble market value is established through years of marketing reputation and high-quality products. High profits, but consumers have no way of distinguishing the authenticity of counterfeit products that look almost fake. After buying, they find that the quality is far from the real product. Therefore, counterfeiting behaviors damage the rights of genuine manufacturers and consumers at the same time, and the profit There are only counterfeit manufacturers...

Problems solved by technology

However, this technology has the following disadvantages: (1) The aluminum foil is easy to be scratched, or warps or even falls off on the surface of the object after losing its viscosity

(2) If the diffraction components shown in this case are to be integrated with multiple structures, it will easily cause difficulties in actual production

(3) Although there is a color change, it cannot be recognized with the naked eye and has a better color rendering effect, so the recognition effect is also reduced

However, this patent can only be applied to flexible materials (such as banknotes), and it cannot be applied to rigid plates (such as credit cards), so the application range of identification is greatly limited
