The main purpose is to select metalloid materials to allow visible light to pass and reflect to show the color. At the same time, with its different thickness when visible light passes through, the wavelength of visible light can be changed, so that the displayed color can also be different, so as to achieve the purpose of changing and selecting the color.

Another object of the present invention is to provide a colored layered structure, which exhibits a color, especially a color with metallic luster.

In order to achieve the above-mentioned main objective, the present invention provides a colored layered structure, including a base layer, a color layer, and a light-reflecting layer. The color layer is made of metalloid and has a thickness to overlap the base layer. The layer is stacked together with the base layer and the color layer to form the layered structure; wherein, the visible light passes through the thickness of the color layer and is reflected on the color layer by the reflective layer to present the color.

In order to achieve the above-mentioned main objective, the present invention provides a control method for changing the color of the layered structure, which controls the thickness of the color layer to change the wavelength of visible light, thereby controlling the color presented.

In order to enable your reviewer to further understand the features and technical content of the present invention, please refer to the following detailed description and drawings of the present invention. However, the accompanying drawings are only for reference and illustration, and are not used to limit the present invention. .

Please refer to FIG. 1 and FIG. 2, which are respectively an exploded schematic diagram and a combined schematic diagram of the first embodiment of the present invention. The present invention provides a colored layered structure and a control method for changing its color. The layered structure includes a base layer 1, a color layer 2, and a reflective layer 10; wherein:

The base layer 1 is the processing material or workpiece to be colored, or the surface of the aforementioned workpiece, and the base layer 1 can be made of a material with a certain structural strength or hardness, such as metal, alloy, glass, or plastic. In this embodiment, the casing is mainly used as a product with a communication function such as a mobile phone. Therefore, in this consideration, the base layer 1 is made of plastic and has an outer surface 11 and an inner surface 12, wherein The outer surface 11 can be provided for the above-mentioned color layer 2 and the reflective layer 10 to be stacked, while the inner surface 12 can be provided for the structure such as the antenna 3 for communication reception and transmission.

The color layer 2 is made of metalloid. The so-called metalloid includes boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), polonium (Po ) And 砈 (At) element materials. In the preferred embodiment of the present invention, silicon is used, and pure silicon (purity above 99%) is better; especially in order to avoid affecting mobile phones or Internet communications If the signal causes interference, the color layer 2 is made of a type of metal because it does not contain metal components, so that the above-mentioned purpose and effect can be achieved, and it is more suitable for appearance applications of communication products such as 5G.

As mentioned above, the color layer 2 has a certain thickness d and overlaps the above-mentioned base layer 1. The silicon material can be plated on the base layer 1 or the reflective layer 10 by a method such as coating. The coating method can be performed by a method such as Vacuum Evaporation, Magnetic Sputtering or Cathode Arc Vapor. In order to improve the adhesion between the base layer 1 and the color layer 2, construction methods such as sand blasting, atmospheric plasma, CORONA treatment, vacuum plasma treatment or vacuum ion source can also be used. In addition, surface treatments such as anti-fingerprint or topcoat protection can also be added to the color layer 2 to increase the service life of the color layer 2. The anti-fingerprint surface treatment can be spray coating or vacuum PVD Coating method processing.

The light-reflecting layer 10 is stacked together with the base layer 1 and the color layer 2 to form the layered structure. In this embodiment, the reflective layer 10 is disposed on the outer surface 11 of the base layer 1, and is sandwiched between the base layer 1 and the color layer 2, so that visible light can pass through the thickness d of the color layer 2 from the outside. At this time, the light source can show a color on the color layer 2 by the reflection of the reflective layer 10. What is explained here is that when visible light passes through the color layer 2 with a specific thickness d and reaches the bottom base layer 1 or the reflective layer 10, the light passes through the refraction in the color layer 2 and can change the wavelength of visible light through optical properties such as silicon. , Plus the changes in the base color and surface roughness of the base layer 1 or the reflective layer 10, resulting in changes in the overall spectrum, so that people can clearly feel the different colors and color depths under the naked eye Variety.

Please refer to FIG. 3 again. The present invention further provides an embodiment in which the base layer 1 or the reflective layer 10 is made of aluminum baking black paint as the base color, and the color layer 2 is made of silicon and formed by a coating method. The thickness d is the coating layer. The film thickness is a graph formed by obtaining spectral peaks when the color layer 2 has a different film thickness of the coating layer.

It can be seen from Figure 3 that the spectral peak, that is, its wavelength, can be changed through the thickness of the coating layer, thereby changing the color presented; at the same time, observing the relationship between the thickness of the coating layer and the color, the color of the coating will show a periodic trend Changes, this trend will be related to the thickness, and the appearance of individual colors is also related to the thickness of the film. Finally, when the coating layer exceeds a certain thickness, the intensity of the light reflected from the coating layer surface is much greater than the intensity of the light penetrating into the coating layer and then refracting, which will cause the coating layer color to slowly change back to the original color of the coating material.

Therefore, it can be seen from Figure 3 that under the control of the base color of the base layer 1 or the reflective layer 10 and other factors, the thickness of the color layer 2 can be used to change the wavelength of visible light, so that the displayed colors are different, and then choose the desired color. The color or color spectrum, and use its corresponding thickness as the color. More importantly, since the color layer 2 used is made of metal-like structure, it can make the rendered color have metallic luster, and at the same time, because it has no metal component, it will not interfere with the signal in applications such as communication.

Therefore, the colored layered structure of the present invention and the control method for changing its color can be obtained by the above-mentioned structure composition.

In addition, as shown in FIG. 4, it is a schematic diagram of the combination of the second embodiment of the present invention. Wherein, the reflective layer 10 can also be formed directly on the outer surface 11 of the base layer 1, that is, the outer surface 11 of the base layer 1 has a reflective effect. For example, the base layer 1 is made of aluminum plate, and the outer surface 11 is painted with baking varnish And other methods, and the preferred paint color is darker, such as black and metallic luster. In addition, the base layer 1 itself can also use surface protection treatment technology to make the base layer 1 have a self-protection layer or other color layers, and the surface treatment technology such as painting, micro-arc oxidation, anodic oxidation treatment and so on.

Moreover, as shown in FIG. 5, it is a schematic diagram of the combination of the third embodiment of the present invention. Wherein, the base layer 1 can also be made of transparent material, such as glass, or transparent plastic material such as acrylic, PC or PET. At this time, the reflective layer 10 is made of opaque or low-transmittance materials, such as paints, inks, metal films, or plastics of various colors. Coating and depositing between the base layer 1 and the color layer 2 by spraying, printing or vacuum coating, etc., achieve the effect of reflecting light.

Furthermore, as shown in FIG. 6, it is a schematic diagram of the combination of the fourth embodiment of the present invention. Among them, the color layer 2 can also be arranged between the base layer 1 and the light reflecting layer 10 according to the above-mentioned third embodiment, that is, the inner surface 12 of the base layer 1 is provided with the color layer 2 in the above-mentioned various ways, and then the light reflecting layer 10 is coated , Deposited on the color layer 2, which can also achieve the effect of reflecting light.
