[0025] Please see Figure 1 This utility model provides a technical solution: a multi-color display element that can display different characters and patterns in the same position. The multi-color display element includes a thin film layer 1 disposed on the upper part; a multi-layer printed light-selective ink layer 2 is disposed below the thin film layer 1. The thin film layer 1 mainly serves as the outermost protective layer for the component during use, preventing the product from being scratched. The multi-layer printed light-selective ink layer 2 is the key ink layer that mainly enables the display of different characters and patterns in the same position. It achieves different display effects mainly by printing different transmissive color inks in multiple layers.

[0026] The multi-color display component also includes an adhesive layer 3 disposed beneath the multi-layer printed light-selective transmissive ink layer 2. The adhesive layer 3 is used to bond the display layer to a specific product when it is necessary to fix or attach it to the product.

[0027] A light-diffusing layer 4 is provided below the adhesive layer 3. The light-diffusing layer 4 is used to generate light and to homogenize the light.

[0028] The multi-color display element also includes protective layers 5 on the upper and lower surfaces. To prevent unnecessary damage during transportation before use, the display element is protected by protective layers 5 on both the upper and lower surfaces. These layers can be removed before installation or use.

[0029] The thin film layer 1 includes any one or a combination of two of the PC layer 11 and the PMMA layer 12. The thin film layer mainly serves as the outermost protective layer. It can be made of PC (polycarbonate), PMMA (polymethyl methacrylate), or a composite of the two materials, all of which can achieve the product requirements of high transparency, low cost, easy processing, and good toughness.

[0030] The multi-layer printed light-selective ink layer 2 includes at least two light-transmitting color ink layers. The display element of this utility model mainly achieves the effect of displaying different characters and patterns in the same position through this multi-layer printed light-selective ink layer 2. Specifically, it involves printing at least two different colors of light-transmitting ink layers in multiple layers, and then cutting out the characters or patterns to be displayed on the corresponding light-transmitting color ink layers. Through the cutout design and the selective transmission of different wavelengths of light by each layer, a rich display effect is achieved.

[0031] In some embodiments, two light-transmitting ink layers are selected: a blue light-transmitting ink layer 22 and a red light-transmitting ink layer 23. Characters or patterns intended to be displayed in red are cut out and printed on the blue light-transmitting ink layer 22, while characters or patterns intended to be displayed in blue are cut out and printed on the red light-transmitting ink layer 23. In the non-cutout areas of the blue light-transmitting ink layer 22, only blue light can pass through, while other colors of light are absorbed. Similarly, in the non-cutout areas of the red light-transmitting ink layer 23, only red light can pass through, while other colors of light are absorbed.

[0032] The multilayer printed light-selective ink layer 2 also includes a semi-transparent silver or soot layer 21 disposed above the light-transmitting ink layer, and a diffusion ink layer 24 and a shock-resistant varnish layer 25 disposed below the light-transmitting ink layer. To enhance the product's appearance when no characters or patterns are displayed, a semi-transparent silver or soot layer 21 with a semi-transparent silver or soot effect is printed below the transparent film layer 1. This semi-transparent silver or soot layer 21 achieves its effect through ink printing, giving it a metallic luster. Furthermore, to ensure more uniform light distribution before passing through the two light-transmitting ink layers, a diffusion ink layer 24 is disposed below the light-transmitting ink layer. This diffusion ink layer 24 is primarily printed using resin diffusion or matting powder-based inks, resulting in more even light dispersion. To prevent the ink from being washed away by heat during injection molding or hot pressing of the printed film product, a shock-resistant varnish layer 25 is disposed below, primarily printed using resin-based transparent inks.

[0033] The adhesive layer 3 includes an adhesive layer 31 and a PC or ABS granular material layer 32 disposed below it; the light-diffusing layer 4 includes a diffusion film layer 41 disposed below the adhesive layer 3, and a multi-color LED light assembly 42 disposed below the diffusion film layer 41. The adhesive layer 3 mainly consists of an adhesive layer 31 and a granular material layer, i.e., a PC or ABS granular material layer 32. The adhesive layer 31 is mainly formed by the solidification of a transparent glue structure, while the PC or ABS granular material layer is a polymer material layer composed of polycarbonate or acrylonitrile-styrene-butadiene copolymer. The lower diffusion film layer 41 also serves to homogenize the light, and the multi-color LED light assembly 42 is mainly for emitting various colors of light.

[0034] The protective layer 5 includes a PE conformal film 51 disposed on the upper part of the thin film layer 1 and a PE film 52 disposed on the lower part of the light-diffusing layer 4. The protective layer 5 is mainly for preventing scratches during transportation and plays a protective role. It can be removed before installation and use at the terminal.

[0035] Working principle:

[0036] 1. When it is necessary to display characters or patterns with a cutout design printed on the red translucent ink layer 23:

[0037] The multi-color LED light group 42 emits blue light. After passing through the diffusion layer 41, the blue light achieves a uniform light effect. The blue light passes through the transparent adhesive layer 3 and the anti-impact varnish layer 25 without damage. The light is further homogenized in the diffusion ink layer 24. Then, the blue light is completely absorbed in the non-perforated area of ​​the red transmissive ink layer 23. Only the blue light in the perforated area can propagate upward. When it passes through the upper blue transmissive ink layer 22, since both the perforated and non-perforated areas can transmit blue light, it has no distinguishing effect on the blue light. As a result, the light transmitted from the thin film layer 1 is the blue light transmitted through the perforated area of ​​the red transmissive ink layer 23, thus achieving the effect of displaying a character or pattern and its corresponding color.

[0038] 2. When it is necessary to display characters or patterns with a cutout design printed on the blue translucent ink layer 22:

[0039] The multi-color LED light group 42 emits red light. After passing through the diffusion layer 41, the red light achieves a uniform light effect. The red light passes through the transparent adhesive layer 3 and the anti-impact varnish layer 25 without damage. The light is further homogenized in the diffusion ink layer 24. Since both the hollow and non-hollow areas of the red transmissive ink layer 23 can transmit red light, it has no distinguishing effect on the red light. All the red light can pass through the red transmissive ink layer 23. When the red light reaches the blue transmissive ink layer 22, since the non-hollow areas can only transmit blue light, the red light is absorbed, while the hollow areas can transmit red light, thus displaying the characters or patterns on them. This results in the light ultimately transmitted from the thin film layer 1 being the red light that is dragged across the hollow areas of the blue transmissive ink layer 22, achieving the effect of displaying another text or pattern and its corresponding color.
