Description

Technical Field

[0001] This invention relates to the field of process technology, specifically to a method for producing luminescent glass patterns and a glass product capable of displaying internally engraved patterns. Background Technology

[0002] Existing solutions for luminescent patterns in glass displays typically involve laser engraving the pattern off the underlying ink layer of the glass, leaving the pre-defined luminescent pattern area blank. When the bottom light source is illuminated, the pattern emits a glow. Please refer to [reference needed]. Figure 1 , Figure 1 This is a schematic diagram of the existing glass luminescent pattern design. When the light source is illuminated, the pattern boundaries are sharp and abrupt, failing to achieve good visual integration with the glass. Furthermore, this method ensures that the pre-designed luminescent pattern remains clearly visible even when the light source is off; in the color showing through the ink overlay, there is a distinct boundary between the laser-engraved white portion of the luminescent pattern and the ink's original color. While the existing method is simple in its process, it offers limited visual appeal and fails to achieve a superior decorative effect. Summary of the Invention

[0003] The purpose of this invention is to provide a method for producing luminescent glass patterns and a glass product capable of displaying engraved patterns, so as to at least solve the problem of the above-mentioned single display effect and inability to achieve better decorative effect.

[0004] To achieve the above objectives, a first aspect of the present invention provides a method for manufacturing a glass luminescent pattern, comprising:

[0005] Engraving patterns within patterned areas of flat glass to create a pattern layer;

[0006] A semi-transparent and semi-reflective film surface is formed by physical vapor deposition of optical materials on the surface of flat glass.

[0007] The film used as the substrate is used as the pattern substrate layer so that the engraved pattern is not visible to the naked eye.

[0008] Optionally, the above-mentioned engraving of patterns within the patterned area of ​​the flat glass includes:

[0009] The method of using a laser to create damage points inside a flat glass plate is used to engrave a pre-defined shape pattern.

[0010] Optionally, the film used as the substrate described above is used as a patterned substrate layer, including:

[0011] Coat the diaphragm with optical adhesive;

[0012] A film coated with optical adhesive is attached to the bottom surface of a flat glass plate as a pattern substrate layer.

[0013] Optionally, the above-mentioned coating of the diaphragm with optical adhesive includes:

[0014] Optical adhesive is applied along the edge of the film, leaving an uncoated portion so that an air layer is left when the film is bonded to the bottom surface of the flat glass.

[0015] A second aspect of the present invention provides a glass article capable of displaying an engraved pattern, comprising:

[0016] Patterned substrate layer;

[0017] A pattern layer with an intricate engraving pattern is located above the pattern substrate layer;

[0018] A semi-transparent, semi-reflective film layer covers the pattern layer.

[0019] Optionally, the patterned substrate layer described above is a film used as a substrate.

[0020] Optionally, an optical adhesive layer is provided between the film and the bottom surface of the patterned layer.

[0021] Optionally, an air layer is provided between the above-mentioned film and the bottom surface of the patterned layer.

[0022] Optionally, the glass product that can display an engraved pattern also includes a light source, which is disposed on the side of the pattern layer.

[0023] A third aspect of the present invention provides an electronic product, including a glass panel layer, wherein the glass panel layer includes a glass article capable of displaying an engraved pattern as described in any of the second aspects above.

[0024] The above technical solution first involves forming an engraved pattern within the patterned area of ​​a flat glass panel. Then, physical vapor deposition using optical materials is performed on the glass surface to create a semi-transparent, semi-reflective film layer with optical effects. This allows the glass to have a mirror-like effect when no light source is applied, resulting in low visibility of the engraved pattern when the light source is off, but clear visibility when the light source is on. Finally, a substrate film is attached to the uncoated side of the glass, serving as the pattern substrate. The front of the glass has a mirror film; the mirror effect of the film further enhances the mirror effect of the coated glass surface, improving the concealment of the engraved pattern. Consequently, the engraved pattern is invisible from both sides of the glass when no light source is applied, thus achieving a unique pattern display effect when combined with a light source.

[0025] This method integrates the engraved pattern with the glass, creating a visually distinct boundary without any obvious dividing line, resulting in a good visual effect when illuminated.

[0026] Other features and advantages of the embodiments of the present invention will be described in detail in the following detailed description section. Attached Figure Description

[0034] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0035] Figure 2 This is a flowchart of a method for creating a glass luminescent pattern according to one embodiment of the present invention. Figure 2 As shown, an embodiment of the present invention provides a method for creating a glass luminescent pattern, the method comprising:

[0036] S110: Engraving a pattern within the patterned area of ​​the flat glass 2 as a pattern layer;

[0037] Figure 4 This is a schematic diagram of an internal engraving provided in one embodiment of the present invention. For example... Figure 4 As shown, this embodiment provides an internal engraving pattern 3.

[0038] S120: Physical vapor deposition is performed on the surface of flat glass 2 using optical materials to form a semi-transparent and semi-reflective film surface.

[0039] Specifically, after PVD coating is applied to the flat glass 2, when the light source 7 is not lit, the coated surface of the flat glass 2 has a mirror effect, the visibility of the engraved pattern 3 is low, and the uncoated surface of the flat glass 2 has a transparent effect, and the engraved pattern 3 is visible.

[0040] When the light source 7 is lit, the engraved pattern 3 is clearly visible on the coated surface of the flat glass 2. This results in different effects on the coated surface when the light source 7 is not emitting light and when it is emitting light.

[0041] Among these methods, the use of PVD coating allows for a wider variety of color options for the mirror.

[0042] S130: Use the film used as the substrate as the pattern substrate layer so that the engraved pattern 3 is not visible to the naked eye.

[0043] The film used as the substrate can be a black film 6 or a film of other colors. The light transmittance of the film should be less than 1%, and it should be able to absorb most of the light.

[0044] In some embodiments of this example, the color of the film selected by the user can match the color of the PVD coating. Specifically, the black film 6 can be matched with various colors of the PVD coating.

[0045] In the above implementation process, the method first engraves an internal pattern 3 within the flat glass 2. After forming the internal pattern 3, physical vapor deposition is performed on the surface of the flat glass 2 using optical materials to form a semi-transparent, semi-reflective PVD film layer 1 with optical effects. This makes the flat glass 2 appear mirror-like when the light source 7 is not lit. The internal pattern 3 within the flat glass 2 has low visibility when the light source 7 is not lit, but becomes clearly visible when the light source 7 is lit. Finally, a black film 6 is attached to the uncoated side of the flat glass 2, serving as a pattern substrate. The front of the flat glass 2 has a mirror film. Under the influence of the black film 6, the mirror effect of the coated surface of the flat glass 2 becomes more pronounced, resulting in a better concealment effect for the internal pattern 3. Thus, when the light source 7 is not lit, the internal pattern 3 is invisible from both sides of the flat glass 2. This, combined with the light source 7, achieves a unique pattern display effect. Furthermore, this method creates an engraved pattern 3 within the flat glass 2, making the engraved pattern 3 an integral part of the flat glass 2, with no obvious dividing line in visual contrast, resulting in a good visual effect when lit.

[0046] In this embodiment, the black film 6 is used as a substrate layer, including:

[0047] Coat the black film 6 with optical adhesive 5;

[0048] A black film 6 coated with optical adhesive 5 is attached to the bottom surface of the flat glass 2 as a pattern substrate.

[0049] Optionally, the black film 6 is coated with optical adhesive 5, including:

[0050] Optical adhesive 5 is applied along the edge of the black film 6, leaving an uncoated portion so that an air layer 4 is left when the black film 6 is bonded to the bottom surface of the flat glass 2.

[0051] Specifically, optical adhesive 5 is applied to the inner ring of the black film 6. The optical adhesive 5 is distributed around the black film 6, but not completely covering it, leaving gaps between the inner rings. This creates an air layer 4 between the black film 6 and the flat glass 2 during bonding, facilitating light propagation and its effect on the engraved pattern 3. The presence of the air layer 4 effectively reduces light absorption by the black film 6, resulting in a better display effect of the luminescent pattern.

[0052] Figure 3 This is a schematic diagram of the luminescent pattern structure of a flat glass 2 after laser engraving and PVD coating, provided by one embodiment of the present invention. Figure 3 As shown, an inner engraving pattern 3 is engraved inside the flat glass 2, a PVD film layer 1 is deposited on the top layer of the flat glass 2, and a black film 6 is attached to the bottom layer of the flat glass 2 using optical adhesive 5. The optical adhesive 5 is distributed around the black film 6, but does not completely cover it, leaving some gaps between the inner rings, so that an air layer 4 is left between the black film 6 and the flat glass 2 when they are attached.

[0053] In this embodiment, engraving a pattern within a patterned area of ​​the flat glass 2 includes: engraving a preset shape pattern by using a laser to focus and form damage points within the flat glass 2.

[0054] Optionally, pattern engraving can be performed in a cleanroom environment using laser focusing.

[0055] In this embodiment, the aforementioned clean environment can be achieved by cleaning the surface of the flat glass 2 with a lint-free cloth and alcohol.

[0056] In this embodiment, an ultraviolet nanolaser is used for laser focusing to achieve in-pattern engraving.

[0057] Specifically, during sample preparation, the surface of the flat glass 2 is first cleaned with a lint-free cloth and alcohol. In a dust-free environment, a computer-controlled laser beam is used to focus an ultraviolet nanolaser on the central part of the flat glass 2. It is important to note that sufficient energy needs to be generated at the focal point to damage the flat glass 2, but the energy above or below the focal point is insufficient to damage the surrounding flat glass 2. The energy at the focal point instantaneously destroys the material, forming a vacuum sphere, thus achieving the effect of creating a damage point. The sphere is approximately 2µm in diameter and is invisible to the naked eye; only bubbles outlining the pre-defined shape pattern are visible.

[0058] In this embodiment, the center wavelength of the ultraviolet nanolaser is 355nm.

[0059] In this embodiment, the threshold of the maximum single-pulse energy of the above-mentioned ultraviolet nanolaser is 200uJ to 250uJ.

[0060] Please refer to Table 1, which shows the parameters of the ultraviolet nanolaser in this embodiment:

[0061] center wavelength 355nm Output power 10～20W Maximum single pulse energy 200~250uJ repetition frequency 50kHz~200kHz Pulse width <15ns Operating temperature 10～30℃

[0062] Table 1 Parameters of the ultraviolet nanolaser

[0063] In this embodiment, the optical adhesive 5 can be OCA adhesive.

[0064] Optionally, the above methods also include:

[0065] A light source 7 is provided on the side of the pattern layer of the flat glass 2. Specifically, after the glass is manufactured using this glass luminescent pattern manufacturing method, the light source 7 can be lit on the side of the flat glass 2.

[0066] Specifically, light source 7 is a side light source. Using a side light source in this method helps maintain the thickness of the product itself, meaning that no additional thickness space is needed to place the light source 7, thus increasing the advantages of this method in electronic product applications. When light source 7 is lit, the engraved pattern 3 can be displayed on the mirror surface, clearly visible with soft edges, blending seamlessly with the mirror effect.

[0067] In this embodiment, before engraving the pattern within the patterned area of ​​the flat glass 2, the process further includes:

[0068] Design an inner engraved pattern 3 that corresponds to the size of the flat glass 2.

[0069] Specifically, an inner engraved pattern 3 corresponding to the size of the flat glass 2 can be designed using Adobe Illustrator software.

[0070] In this embodiment, the inner engraved pattern 3, which corresponds to the size of the flat glass 2, includes:

[0071] The engraved pattern is composed of dots or planes. Specifically, one or more shapes, either dots or planes, are selected to design the engraved pattern 3, with the preferred choice being an engraved pattern composed of dots.

[0072] Specifically, based on the size of the flat glass 2 itself, use Adobe Illustrator software to design an inner engraved pattern 3 of the corresponding size. When designing the pattern, it should be noted that the pattern composed of dots has a better hiding effect than the pattern composed of blocks, and the refraction effect when the light is emitted is better and more beautiful.

[0073] This invention also provides a glass article capable of displaying an internally engraved pattern, comprising:

[0074] Patterned substrate layer;

[0075] A pattern layer with an inner engraved pattern 3 is located on top of the pattern substrate layer;

[0076] A semi-transparent, semi-reflective film layer covers the pattern layer.

[0077] Specifically, when the light source 7 is lit, the engraved pattern 3 on the pattern layer of the glass product is clearly visible. However, when the light source 7 is not lit, the engraved pattern 3 is not visible from either side of the flat glass 2. This, combined with the light source 7, achieves a unique pattern display effect. Furthermore, the glass product displaying the engraved pattern does not have a visually distinct dividing line, providing a good visual effect when illuminated.

[0078] In some embodiments of this example, the patterned substrate layer is a film used as a substrate. The film used as a substrate can be a black film 6 or a film of other colors, and the film's transmittance should be less than 1%, and it should be able to absorb most of the light.

[0079] In some embodiments of this example, an optical adhesive layer is provided between the film and the bottom surface of the patterned layer.

[0080] In some embodiments of this example, an air layer 4 is provided between the film and the bottom surface of the patterned layer.

[0081] Specifically, optical adhesive 5 can be applied to the inner ring of the black film 6. The optical adhesive 5 is distributed around the black film 6, but not completely covering it, leaving gaps between the inner rings. This creates an air layer 4 between the black film 6 and the flat glass 2 during bonding, facilitating light propagation and its effect on the engraved pattern 3. The presence of the air layer 4 effectively reduces the absorption of light by the black film 6, thereby achieving a better display effect of the luminescent pattern.

[0082] In some embodiments of this example, the glass product capable of displaying an engraved pattern further includes a light source 7, which is disposed on the side of the pattern layer.

[0083] Specifically, placing the light source on the side of the pattern layer helps maintain the thickness of the product itself, meaning that there is no need to add extra thickness space to place the light source 7.

[0084] The present invention also provides an electronic product, including a glass panel layer, the glass panel layer including the glass article described above that can display an engraved pattern.

[0085] Specifically, the aforementioned glass products capable of displaying engraved patterns can be applied to electronic products such as mobile phones, tablets, wearable watches, cameras, and automobiles. For example, by using such glass products in the area where the logo of a mobile phone / tablet / wearable watch / camera is located, the glass product can display the corresponding logo when visible light is present, while the logo remains invisible when no visible light is present, thus achieving a unique pattern display effect.

[0086] The optional embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the embodiments of the present invention are not limited to the specific details described above. Within the scope of the technical concept of the embodiments of the present invention, various simple modifications can be made to the technical solutions of the embodiments of the present invention, and these simple modifications all fall within the protection scope of the embodiments of the present invention. It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the embodiments of the present invention will not further describe the various possible combinations.

[0087] Furthermore, various different embodiments of the present invention can be combined in any way, as long as they do not violate the spirit of the embodiments of the present invention, they should also be regarded as the content disclosed by the embodiments of the present invention.
