Therefore, the areas illustrated in the drawings are schematic, and the shapes of the areas shown illustrate specific shapes of the areas of an element, but are not intended to be limiting.

[0045] Please see Figure 1This utility model provides a cover plate assembly 100, including a light-transmitting substrate 101 and a reflective pattern layer 102, a selective shielding layer 103, and a transmissive pattern layer 104 disposed on one side of the light-transmitting substrate 101. The light-transmitting substrate 101 provides mechanical support for each functional layer and is light-transmitting to ensure unobstructed reflection paths of ambient light and transmission paths of the light source. The light transmittance of the light-transmitting substrate 101 is, for example, greater than or equal to 90%. The light-transmitting substrate 101 includes, but is not limited to, a glass substrate, a tempered glass substrate, etc. Tempered glass may include physically tempered glass or chemically tempered glass, etc. In practical applications, the light-transmitting substrate 101 may also be made of a substrate such as a transparent polymer.

[0046] In some embodiments, the light-transmitting substrate 101 is covered with an anti-reflection layer (not shown) on at least one side of the surface adjacent to and away from the reflective pattern layer 102; that is, at least one of the two surfaces of the light-transmitting substrate 101 adjacent to and away from the reflective pattern layer 102 is covered with an anti-reflection layer. The anti-reflection layer is used to improve the light transmittance of the light-transmitting substrate 101, thereby improving the optical performance of the light-transmitting substrate 101. In some embodiments, at least one of the two surfaces of the light-transmitting substrate 101 adjacent to and away from the reflective pattern layer 102 may be coated to form an anti-reflection layer. Of the two surfaces of the light-transmitting substrate 101 adjacent to and away from the reflective pattern layer 102, one surface (i.e., Figure 1 The surface of the medium-transmittance substrate 101 on the lower side is provided with a reflective pattern layer 102, a selective shielding layer 103 and a transmissive pattern layer 104.

[0047] The reflective pattern layer 102 is adjacent to the light-transmitting substrate 101, and the pattern of the reflective pattern layer 102 is visible by reflecting ambient light. Ambient light (such as natural light or indoor lighting) passes through the light-transmitting substrate 101 from the side away from the reflective pattern layer 102 and is reflected by the reflective pattern layer 102. The reflected light is as follows: Figure 1 As shown by the solid arrow, the reflected light can be reflected to the human eye, allowing the human eye to see the pattern on the reflective pattern layer 102. The reflective pattern layer 102 can clearly display the pattern under ambient light, and the user can see the pattern even when the light source 200 is turned off, enhancing the visual effect of the product.

[0048] The reflective pattern layer 102 includes, for example, a fifth substrate and third reflective pigment particles disposed within the fifth substrate. The fifth substrate is, for example, a transparent or translucent resin matrix. The resin possesses good adhesion, mechanical properties, and optical stability, ensuring that the reflective pattern layer 102 is firmly adhered to the light-transmitting substrate 101. The third reflective pigment particles include, for example, aluminum powder, TiO2, silver powder, or other metal oxides. These pigments typically have a reflectivity between 80% and 95%, effectively reflecting ambient light. The mass percentage of the third reflective pigment particles is typically 10% to 30%, a range that ensures sufficient reflectivity while maintaining ink flow and coating performance.

[0049] In some embodiments, the reflective pattern layer 102 can be coated onto the light-transmitting substrate 101, for example, by inkjet printing, to form the pattern of the reflective pattern layer 102. Inkjet printing technology can control the formation of the pattern with micron-level precision (±10μm), ensuring the clarity and accuracy of the pattern. Moreover, this technology can easily realize complex pattern designs, such as text, graphics, icons, etc. During the inkjet printing process, ink is ejected from the printhead onto the light-transmitting substrate 101 to form the reflective pattern layer 102. During the curing process, the ink forms a uniform thin film, fixing the third reflective pigment particles in the fifth substrate.

[0050] On the glass cover (i.e., the light-transmitting substrate 101) of electronic products such as smartphones, tablets, and smartwatches, the reflective pattern layer 102 can be used to display brand logos, decorative patterns, or functional icons, enhancing the product's visual appeal. In automotive dashboards, center consoles, and other areas, the reflective pattern layer 102 can be used to display vehicle information or decorative patterns, while reducing reliance on interior lighting. On outdoor billboards, bus stop signs, and other equipment, the reflective pattern layer 102 can clearly display information under natural light, reducing energy consumption.

[0051] A selective shielding layer 103 is at least partially disposed between the transmissive pattern layer 104 and the reflective pattern layer 102; the orthographic projections of the pattern of the transmissive pattern layer 104 and the pattern of the reflective pattern layer 102 onto the light-transmitting substrate 101 are offset; the selective shielding layer 103 is used to block light from the light source 200 illuminating the non-patterned areas of the transmissive pattern layer 104, while allowing light from the light source 200 illuminating the patterned areas of the transmissive pattern layer 104 to pass through, the path of which is as follows: Figure 1 As shown by the dashed arrow in the image.

[0052] The light source 200 is located on the side of the cover plate assembly 100 away from the light-transmitting substrate 101, that is, Figure 1 The lower side of the middle cover assembly 100. The light source 200 can be a backlight or other light-emitting object that can provide illumination. The backlight includes, but is not limited to, a backlight module, a light guide plate, an LED light assembly, etc.

[0053] The cover plate assembly 100 provided in this application can switch between two modes by turning the light source 200 on or off. These two modes are a reflection mode and a transmission-reflection coexistence mode. By offsetting the orthographic projections of the pattern of the transmission pattern layer 104 and the pattern of the reflection pattern layer 102 onto the light-transmitting substrate 101, i.e., preventing them from overlapping in space, the patterns of the transmission pattern layer 104 and the reflection pattern layer 102 will not interfere with each other, ensuring that the patterns of both the transmission pattern layer 104 and the reflection pattern layer 102 are clearly distinguishable in different modes. Specifically, the two modes include a reflection mode and a transmission-reflection coexistence mode. In reflection mode, the light source 200 is off, the pattern of the reflection pattern layer 102 can be displayed under ambient light, while the pattern of the transmission pattern layer 104 is not displayed. In the transmission and reflection coexistence mode, the light source 200 is turned on. The pattern of the transmission pattern layer 104 is displayed under the illumination of the light source 200, while the pattern of the reflection pattern layer 102 can be displayed under ambient light. Furthermore, the patterns of the transmission pattern layer 104 and the reflection pattern layer 102 do not interfere with each other, ensuring the independence of the display effect. Thus, by turning the light source 200 on or off, a dynamic switching effect between different patterns in the same area is achieved. For example, when the light source 200 is off, a brand logo (the pattern of the reflection pattern layer 102) is displayed; when the light source 200 is on, preset information (the pattern of the transmission pattern layer 104) is displayed. In some embodiments, the color, brightness, and other effects of the displayed information can be adjusted by adjusting the parameters of the light source 200 (e.g., color, light intensity). For example, the brightness of the light source 200 can be changed in real time to dynamically change the brightness of the displayed information.

[0054] In reflection mode, selecting the occlusion layer 103 can simultaneously reflect ambient light and block the transmission pattern layer 104, preventing ambient light from illuminating the transmission pattern layer 104 and thus making the pattern of the transmission pattern layer 104 invisible in reflection mode. When the light source 200 illuminates the transmission pattern layer 104 (i.e., in a coexisting transmission and reflection mode), selecting the occlusion layer 103 blocks light from the light source 200 illuminating the non-patterned areas of the transmission pattern layer 104, while allowing light from the light source 200 to pass through the patterned areas of the transmission pattern layer 104. This allows the pattern of the transmission pattern layer 104 to be visible when the light source 200 is on.

[0055] This application achieves independent display effects in both reflection mode and transmission-reflection coexistence mode by misaligning the orthographic projections of the pattern of the transmission pattern layer 104 and the pattern of the reflection pattern layer 102 onto the light-transmitting substrate 101 and by utilizing the optical properties of the selective blocking layer 103. This ensures that both the pattern of the transmission pattern layer 104 and the pattern of the reflection pattern layer 102 are clearly distinguishable. Furthermore, it enhances the visual experience of the product by dynamically switching modes and light source parameters (such as color and light intensity).

[0056] To achieve the function of selectively blocking the light source 200, the selectively blocking layer 103 blocks light from illuminating the non-patterned areas of the transmissive pattern layer 104 while allowing light from the light source 200 to pass through the patterned areas of the transmissive pattern layer 104. In some embodiments, the selectively blocking layer 103 includes a semi-transparent and semi-reflective layer 103a and a light-shielding layer 103b. The light-shielding layer 103b is disposed on the side of the transmissive pattern layer 104 away from the reflective pattern layer 102, and the orthographic projection of the light-shielding layer 103b onto the transmissive substrate 101 is offset from the orthographic projection of the patterned area of ​​the transmissive pattern layer 104 onto the transmissive substrate 101; that is, the orthographic projection of the light-shielding layer 103b onto the transmissive substrate 101 coincides with the non-patterned area of ​​the transmissive pattern layer 104. In some examples, the non-patterned areas of the transmissive pattern layer 104 are hollowed out. In this case, a portion of the light-shielding layer 103b fills the hollowed-out space containing the non-patterned areas of the transmissive pattern layer 104. It should be noted that... Figure 1 The transmissive pattern layer 104 and the light-shielding layer 103b are shown schematically only in the order of processing. In reality, a portion of the light-shielding layer 103b fills the hollow space where the non-patterned area of ​​the transmissive pattern layer 104 is located. In other examples, the non-patterned area of ​​the transmissive pattern layer 104 has a solid portion; for example, the orthographic projection of the transmissive pattern layer 104 onto the light-transmitting substrate 101 covers the entire light-transmitting substrate 101. In this case, the pattern of the transmissive pattern layer 104 is defined by the hollow portion of the light-shielding layer 103b. That is, the area of ​​the transmissive pattern layer 104 not blocked by the light-shielding layer 103b is the patterned area of ​​the transmissive pattern layer 104, while the area of ​​the transmissive pattern layer 104 blocked by the light-shielding layer 103b is the non-patterned area of ​​the transmissive pattern layer 104.

[0057] The light-shielding layer 103b is used to block light from the light source 200 illuminating the non-patterned area of ​​the transmissive pattern layer 104; the semi-transparent and semi-reflective layer 103a is disposed between the reflective pattern layer 102 and the transmissive pattern layer 104, and the orthogonal projection of the semi-transparent and semi-reflective layer 103a onto the transmissive substrate 101 covers the transmissive substrate 101; the semi-transparent and semi-reflective layer 103a is used to reflect part of the ambient light and transmit part of the light emitted by the light source 200 and transmitted through the patterned area of ​​the transmissive pattern layer 104. It should be noted that... Figure 1 The semi-transparent and semi-reflective layer 103a is shown schematically only in the order of processing. In actual applications, at least a portion of the semi-transparent and semi-reflective layer 103a fills the hollow space where the non-pattern area of ​​the reflective pattern layer 102 is located.

[0058] In the transmission and reflection coexistence mode, under the blocking effect of the light-shielding layer 103b, the light emitted by the light source 200 can only illuminate the patterned area of ​​the transmission pattern layer 104, and cannot illuminate the non-patterned area of ​​the transmission pattern layer 104, thereby ensuring that light can only pass through the patterned area of ​​the transmission pattern layer 104. In some embodiments, the light-shielding layer 103b includes a second substrate and first reflective pigment particles disposed in the second substrate. The function of the second substrate is similar to that of the fifth substrate described above, and for example, the same material can be used.

[0059] In some embodiments, the first reflective pigment particles may be pigment particles with high reflectivity and high opacity, such as carbon black, iron oxide, etc.

[0060] In some embodiments, the light-shielding layer 103b can be fabricated, for example, by inkjet printing.

[0061] The semi-transparent and semi-reflective layer 103a is used to reflect part of the ambient light and transmit part of the light emitted by the light source 200 that passes through the area containing the pattern of the transmissive pattern layer 104. Specifically, in reflection mode, ambient light penetrates the light-transmitting substrate 101, reaches the portion of the reflective pattern layer 102 and the semi-transparent and semi-reflective layer 103a not covered by the reflective pattern layer 102, and is reflected to the human eye, so that the human eye can only see the pattern of the reflective pattern layer 102 and cannot see the pattern of the transmissive pattern layer 104. In the transmission and reflection coexistence mode, the light emitted by the light source 200 can only illuminate the area containing the pattern of the transmissive pattern layer 104, and is transmitted to the semi-transparent and semi-reflective layer 103a, and then transmitted from the semi-transparent and semi-reflective layer 103a to the human eye, so that the human eye can see the pattern of the transmissive pattern layer 104. Since the semi-transparent and semi-reflective layer 103a covers the entire light-transmitting substrate 101, it can ensure that the patterns of the reflective pattern layer 102 and the transmissive pattern layer 104 do not interfere with each other in different modes, thereby realizing the independent display of two different patterns. Furthermore, by turning the light source 200 on or off, dynamic switching between the reflection mode and the transmission and reflection coexistence mode can be achieved. On this basis, the color, brightness, and other effects of the pattern of the transmissive pattern layer 104 can be adjusted by adjusting the parameters of the light source 200 (such as color and light intensity). For example, the brightness of the light source 200 can be changed in real time so that the brightness of the pattern of the transmissive pattern layer 104 changes dynamically.

[0062] like Figure 2 As shown, in reflective mode, the human eye can see the patterns on reflective pattern layer 102, such as "girl," "animal," "flower," "sun," and the "BOE" trademark. Figure 3As shown, in the transmission and reflection coexistence mode, when the light source 200 is turned on, the hidden transmission pattern layer 104, including elements such as "flying birds," "musical notes," "butterflies," and "sun halos," is revealed and visible to the human eye. This provides users with a more vibrant, colorful, and dynamic visual experience from electronic products. It should be noted that, compared to... Figure 2 and Figure 3 It is known that in the transmission and reflection coexistence mode, the pattern of the reflection pattern layer 102 can still be displayed. In some embodiments, the pattern of the reflection pattern layer 102 can be made brighter in the transmission and reflection coexistence mode by making the light-shielding layer 103b have a cutout in the area where the pattern of the reflection pattern layer 102 is located, or by reducing the thickness of the light-shielding layer 103b.

[0063] In some embodiments, the translucent layer 103a includes a first substrate and reflective pigment particles and first transmissive pigment particles disposed in the first substrate. The first substrate functions similarly to the fifth substrate described above and may, for example, be made of the same material. Further, in some embodiments, the transmittance of the translucent layer 103a is greater than or equal to 30% and less than or equal to 70%. This specific range is chosen to achieve optimal optical performance and display effect in both reflective and transmissive-reflective modes. To ensure that the transmittance of the translucent layer 103a is greater than or equal to 30% and less than or equal to 70%, the mass percentage of reflective pigment particles is greater than or equal to 20% and less than or equal to 40%; the mass percentage of first transmissive pigment particles is greater than or equal to 1% and less than or equal to 20%.

[0064] The optical properties of the translucent and reflective layer 103a are primarily determined by its composition. The translucent and reflective layer 103a contains a certain proportion of reflective pigment particles and first-transmittance pigment particles. By adjusting the mass percentage of the reflective pigment particles, the intensity of the transmitted light from the translucent and reflective layer 103a can be adjusted, thereby regulating the brightness of the pattern displayed on the transmissive pattern layer 104 in the coexistence of transmission and reflection. Of course, in practical applications, the brightness of the pattern displayed on the transmissive pattern layer 104 can also be directly affected by adjusting the luminous intensity of the light source 200.

[0065] In some embodiments, the transmissive pattern layer 104 includes a fourth substrate and second transmissive pigment particles disposed in the fourth substrate. The fourth substrate functions similarly to the fifth substrate described above and may, for example, be made of the same material. The second transmissive pigment particles may be made of the same material as the first transmissive pigment particles or may be made of different materials. The second transmissive pigment particles have different light transmittances than the first transmissive pigment particles. The transmissive pattern layer 104 may be coated, for example, by inkjet printing to form the pattern of the transmissive pattern layer 104.

[0066] To achieve the function of selecting the occlusion layer 103, in other embodiments, such as Figure 4As shown, the selected shielding layer 103 includes a microporous light-shielding layer 103c, which is disposed between the reflective pattern layer 102 and the transmissive pattern layer 104, and the orthogonal projection of the microporous light-shielding layer 103c onto the transmissive substrate 101 covers the transmissive substrate 101. It should be noted that... Figure 4 The microporous light-shielding layer 103c is shown schematically only in the order of processing. In practical applications, at least a portion of the microporous light-shielding layer 103c fills the blank space where the non-patterned area of ​​the reflective pattern layer 102 is located. The microporous light-shielding layer 103c is provided with a plurality of light-transmitting micropores 1031 arranged in a preset pattern A. The orthographic projection of the pattern of the transmissive pattern layer 104 onto the light-transmitting substrate 101 at least covers the orthographic projection of each light-transmitting micropore 1031 onto the light-transmitting substrate 101. In some examples, such as Figure 4 , Figure 5 and Figure 6 As shown, the transmissive pattern layer 104 is composed of continuous solid parts in the patterned area, and multiple light-transmitting micro-holes 1031 are arranged in a preset pattern A. The area where the preset pattern A is located coincides with the orthographic projection of the patterned area of ​​the transmissive pattern layer 104 onto the light-transmitting substrate 101. The areas of the micro-hole light-shielding layer 103c other than the area where the preset pattern A is located are used to block the light emitted by the light source 200. The area where the preset pattern A is located in the micro-hole light-shielding layer 103c is used to transmit light emitted by the light source 200 and transmitted through the patterned area of ​​the transmissive pattern layer 104 through each light-transmitting micro-hole 1031. Optionally, as Figure 10 As shown, the solid portion of the transmissive pattern layer 104 in the patterned region can at least partially fill each of the light-transmitting micro-holes 1031. The portion 104a filling each light-transmitting micro-hole 1031 can either completely fill the light-transmitting micro-hole 1031 or partially fill it. In other examples, the transmissive pattern layer 104 in the patterned region is composed of multiple non-continuous solid portions, for example, such as... Figure 11 As shown, the transmissive pattern layer 104 may consist only of solid portions filling each of the light-transmitting micro-holes 1031. These solid portions may completely fill the light-transmitting micro-holes 1031 or partially fill them. In some other examples, the transmissive pattern layer 104 is composed of multiple non-continuous solid portions in the patterned area, such as... Figure 12 As shown, these solid parts are located outside each light-transmitting micro-aperture 1031, and the orthographic projection of each solid part on the light-transmitting substrate 101 at least covers the orthographic projection of each light-transmitting micro-aperture 1031 on the light-transmitting substrate 101. In some other examples, such as Figure 13As shown, the transmissive pattern layer 104 is composed of multiple non-continuous solid parts in the pattern area. A portion of these solid parts is filled in each of the light-transmitting micro-holes 1031, and another portion is located outside each of the light-transmitting micro-holes 1031. The portion filled in each of the light-transmitting micro-holes 1031 can completely fill the light-transmitting micro-holes 1031 or partially fill the light-transmitting micro-holes 1031.

[0067] In reflection mode, the light source 200 is turned off, and ambient light penetrates the light-transmitting substrate 101, reaching the portion of the reflective pattern layer 102 and the microporous light-shielding layer 103c not covered by the reflective pattern layer 102. After being reflected by both, it returns to the human eye. Because the light-transmitting micropores 1031 are very small and densely packed, in some embodiments, such as... Figure 6 As shown, the diameter φ of the light-transmitting micro-hole 1031 is less than or equal to 30 μm. In some embodiments, the spacing between any two adjacent light-transmitting micro-holes 1031 (e.g., including spacing A and spacing B) is less than or equal to 100 μm. The specific values ​​of the diameter and spacing of the light-transmitting micro-holes 1031 can be set according to the pattern, thickness, and transmittance of the transmission pattern layer 104. Figure 5 As shown, the light-transmitting micro-holes 1031 are formed, for example, by high-precision laser engraving technology. These light-transmitting micro-holes 1031 not only transmit light from the light source 200, but also reflect some ambient light.

[0068] In the transmission and reflection coexistence mode, the light source 200 is turned on, and light passes through the transmission pattern layer 104 to reach the microporous light-shielding layer 103c. Since the orthographic projection of the microporous light-shielding layer 103c onto the light-transmitting substrate 101 covers the entire light-transmitting substrate 101, the areas of the microporous light-shielding layer 103c other than the area where the preset pattern A is located can block the light emitted by the light source 200, while the area where the preset pattern A is located, formed by the multiple light-transmitting micropores 1031 of the microporous light-shielding layer 103c, can transmit the light emitted by the light source 200 and passing through the area where the pattern is located in the transmission pattern layer 104, and reach the human eye, so that the human eye can see the pattern in the transmission pattern layer 104.

[0069] In some embodiments, such as Figure 7As shown, the microporous light-shielding layer 103c has a textured structure on the side near the light-transmitting substrate 101 to meet different visual needs and product design requirements. The microporous light-shielding layer 103c can include, but is not limited to, solid colors, brushed textures, wood grain, and stone textures. Solid colors are single colors used to provide a uniform background effect. Brushed textures mimic the effect of brushed metal. Wood grain mimics the texture of natural wood. Stone texture mimics the texture of stone. The textured structure can be applied using high-precision inkjet printing technology. This technology not only achieves high-precision pattern reproduction but also ensures the clarity and consistency of the texture. High-precision inkjet printing technology sprays ink into the substrate surface in the form of tiny droplets through a printhead to form the desired pattern. The precision and control capability of the printhead determine the resolution and quality of the printed pattern. Modern inkjet printing technology can achieve micron-level precision and is suitable for printing high-precision patterns.

[0070] like Figure 8 As shown, in reflection mode, the human eye can see the pattern and texture of the reflective pattern layer 102, such as the "BOE" trademark. The texture is visible because a portion of the microporous light-shielding layer 103c fills the blank space of the non-patterned area of ​​the reflective pattern layer 102. That is, the portion of the microporous light-shielding layer 103c, excluding the pattern corresponding to the "BOE" trademark, is adjacent to the light-transmitting substrate 101, allowing it to reflect ambient light and be detected by the user. Figure 9 As shown, in the transmission and reflection coexistence mode, when the light source is turned on, the pattern of the hidden "lotus" transmission pattern layer 104 is revealed and seen by the human eye.

[0071] In some embodiments, the microporous light-shielding layer 103c includes a third substrate and second reflective pigment particles disposed in the third substrate. The third substrate functions similarly to the fifth substrate described above, and may, for example, be made of the same material. The second reflective pigment particles may be made of the same material as the first reflective pigment particles, or they may be made of different materials. The second reflective pigment particles have different light transmittances than the first reflective pigment particles.

[0072] As another technical solution, this application embodiment also provides an electronic device, including: a light source 200 and the cover plate assembly 100 provided in this application embodiment. The cover plate assembly 100 is disposed on the light-emitting side of the light source 200.

[0073] It should be understood that the above embodiments are merely exemplary implementations used to illustrate the principle of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
