Hereinafter, the manufacturing process of the light-transmitting plate body of some embodiments of the present disclosure will be described with reference to the drawings.

In order to form the light-transmissive plate body of the present disclosure, in some embodiments, as shown in FIG. 1, a transparent substrate 100 is first provided, which includes two opposite first sides 100a and second sides 100b, one of which is laterally opposite. light source. For example, the transparent substrate 100 can be a plastic substrate, a glass substrate, or a combination thereof. When the transparent substrate 100 is a plastic substrate, the plastic substrate may be an acrylic substrate having a surface hardness of 5H or more. The acrylic substrate has good light transmission characteristics and high surface hardness and is not easily scratched. In addition, the acrylic substrate has high strength and is not easily broken due to impact. Therefore, when the transparent substrate 100 is located at the outermost side, the transparent substrate can be used It is the decorative board of the outermost layer of the electronic device. The thickness of the transparent substrate 100 can be adjusted according to the needs of use, for example, 0.5 mm to 1.5 mm. Generally, a transparent substrate 100 having a light transmittance of 10% to 20% can be used, but not limited thereto.

Next, as shown in FIG. 2, a metal layer 201 having a certain light transmittance is formed on one side of the transparent substrate 100 facing the light source (the first side 100a or the second side 100b) (assuming the first side 100a faces the light source) The metal layer 201 is formed on the first side 100a, and the first side 100a will be described below as an example. In some embodiments, the light transmittance of the metal layer 201 may be 10% to 20%, preferably 10% to 12%. The design of the transmittance range of the above metal layer is considered when the transmittance of the metal layer is too small (for example, 10% or less), the metallic luster cannot be exhibited under the general light source, and the color of the color ink layer is transparent; When the transmittance of the metal layer is too large (for example, 20% or more), the color of the metal is too strong when there is light, and the color of the color ink layer cannot be exhibited. The metal layer 201 allows the light-transmitting plate body to have a mirror-like effect and a metallic color in the case of insufficient light or no backlight. For example, metal layer 201 can be formed of aluminum, silver, tin, copper, chromium, chromium-iron alloys, chromium-cobalt alloys, chromium-nickel alloys, chromium-copper alloys, combinations of the foregoing, or other suitable metals. In some embodiments, the metal layer 201 may have a thickness of 0.01 mm to 0.5 mm, such as 0.01 mm to 0.02 mm, and a metallic color tone of 250 GU to 450 GU. Alternatively, the metal layer 201 may be formed by vacuum sputtering, vapor deposition, non-conductive vacuum metallization (NCVM), water plating, or other suitable method.

Next, referring to FIG. 3A, the color ink layer 301 is applied onto the metal layer 201 to form the light-transmitting plate body 300A of the present disclosure. In some embodiments, the color ink layer 301 has a thickness of 0.005 mm to 0.015 mm and a light transmittance of 20% to 50%. The design of the light transmittance range of the above color ink layer considers that when the light transmittance of the color ink layer is less than 20%, the color of the color ink layer is already present under the general light source; conversely, the light transmittance of the color ink layer. When it is more than 50%, the color of the color ink layer cannot be rendered or the color is light when there is light. The color ink layer 301 converts the translucent plate body 300A into a color of the color ink layer 301 from the mirror-like effect and the metallic color which are originally exhibited in the dark when the light is present. The color of the color ink layer 301 is any color other than white. For example, the color of the color ink layer 301 can be red, yellow, blue, green, orange, black, or other suitable color (eg, a color that meets the design requirements). The color ink layer 301 can be formed by screen printing, ink jetting, or other suitable method.

In some embodiments, the color ink layer 301 may include two or more different portions, such as 301a and 301b shown in FIG. 3B, such that the light transmissive plate 300B may exhibit two or More blocks with different colors.

In other embodiments, as shown in FIG. 3C, the color ink layer 301 may include a single color, but portions having different light transmittances (for example, 301c and 301d) to form the light-transmitting plate body 300C. The portions of the different light transmittances described above enable the light-transmitting plate body 300C to exhibit a gradual effect in the presence of light. For example, the two portions 301c and 301d of the color ink layer 301 can have different thicknesses and different light transmittances.

In addition, in some other embodiments, the color ink layer 301 may include two or more colors and portions having different light transmittances, so that the light-transmitting plate body can exhibit richer colors and gradients when there is light. effect.

Next, as shown in FIG. 4, it may be in the light transmissive plate body 300A as needed. A saturation enhancement unit 401 is further formed on the color ink layer 301 to form a light-transmitting plate body 400A. The saturation enhancement unit 401 allows the light transmissive plate 400A to have a more saturated color than the light transmissive plate 300A when there is light. In some embodiments, the saturation enhancement unit 401 can be a white ink layer having a thickness of 0.01 mm or less and a light transmittance of 5% to 10%. The design of the light transmittance range of the above white ink layer is considered to be the color of the color ink layer when the light transmittance of the white ink layer is less than 5%, and the light transmittance of the white ink layer. When it is more than 10%, the color becomes lighter or darker after light transmission. When the saturation enhancement unit 401 is a white ink layer, it can be formed by ink jet, screen printing or other suitable method. In some other embodiments, the saturation enhancement unit 401 can also be a homogenizer, a light guide, a backlight, or a combination thereof.

Although the saturation enhancement unit 401 of FIG. 4 is formed on the light-transmissive plate body 300A of FIG. 3, it should be understood that the above-mentioned saturation enhancement unit 401 may be formed as needed in the other light-transmissive plate body of the present disclosure ( For example, on the color ink layer of the light-transmitting plate body 300B of FIG. 3B or the light-transmitting plate body 300C of FIG. 3C.

In some other embodiments, a light transmissive pattern layer may be formed on the second side 100b of the transparent substrate (the side on which the corresponding surface is not provided with the metal layer 201), which may be through engraving or the like. The lines formed on the second side (for example, hair, checkerboard, sand blasting, concentric circles, carbon fiber, stripe, etc.) are used to increase the richness and enhance the surface texture.

Next, as shown in FIG. 5, in some embodiments, in order to form the light-transmitting plate module 500 of the present disclosure, the light source A may be disposed on the first side 100a of the light-transmitting plate body 400A so that the first side 100a faces For light source A. The light source A is used to control the color of the light transmissive plate module 500. At least in part due to a metal layer with appropriate light transmission 201 and the color ink layer 301, when the light source plate module 500 is turned on, the color of the color ink layer 301 can be observed by the observer B on the other side, and when the light source A is turned off, the observer B can A mirror-like effect and metallic color were observed. The light source A can be a point light source, a line light source, a surface light source, a combination thereof, or other suitable type, and can be a backlight module formed by an LED or a cold cathode and a light guide plate. For example, light source A can be a screen backlight, a keyboard backlight, a mouse backlight, or other suitable light source. Alternatively, the light source A may be disposed on the second side 100b of the light-transmitting plate body 400A. In some other embodiments, the light source A may be disposed on one side of the other light transmissive plate body (for example, 300B, 300C, or other light transmissive plate body including the saturation enhancement unit) of the present disclosure to form a discolorable light transmissive plate. Module.

For example, when the light source A is the backlight of the notebook screen disposed on the first side 100a of the transparent plate body 400A, the light-transmitting plate body 400A can be the mark L (logo) of the back surface 601 of the notebook battery 600, as described in Figure 6 shows. When the notebook 600 is not turned on without the screen backlight, the observer B on the second side 100b can see the sign L having the mirror-like effect and the metallic color, and when the notebook 600 is turned on and has the screen backlight, the observation is made. B can see the logo L with a color of the color of the ink layer (for example: orange, blue, yellow, red, black, or other suitable color). The mark L can be machined into different shapes by mechanical processing or other suitable methods (for example, computer numerical control machine tools) according to design requirements (for example: square, circle, letter shape, animal shape, character shape, or other) Designed to meet the needs of the design). The step of the above-described forming process may be performed before the formation of the metal layer on the transparent substrate, after the formation of the color ink layer, or at other appropriate timings.

In summary, the light-transmitting plate body of the present disclosure includes a metal layer of a suitable light transmittance and a color ink layer, so that a light source is disposed on the light-transmitting plate body. The light transmissive plate module can produce discoloration when the light source is turned off and the light source is turned on.
