Description

Glass cover plates, display devices, vehicles, and manufacturing methods of glass cover plates Technical Field

[0001] This disclosure relates to the field of display screen printing technology, and more specifically, to a glass cover, a display device, a vehicle, and a method for manufacturing the glass cover. Background Technology

[0002] In related technologies, automotive center console screens typically include a main screen and a secondary screen. When driving, the main screen displays vehicle-related information or controls functions such as the car audio and air conditioning, while the secondary screen is primarily for entertainment and interaction for the passenger in the front seat. Additionally, glass covers are usually installed over the main and secondary screens. To enhance the aesthetics of the center console screen, such as by obscuring the main screen or its surrounding area to prevent the internal structure from being seen through the glass cover, a bezel is typically created on the glass cover to form a border between the main and secondary screens. This border usually features a single, pure black / gray design. When the screen is not in use and is in a off-center state, the screen and its surrounding border only display black or gray, resulting in a monotonous color scheme that clashes with the overall interior design of the vehicle. In order to improve this situation, related technologies usually set textures and patterns in the bezel area. When the vehicle is in motion, the main screen is usually in a bright state, while the secondary screen is in a black state when it is not in use. There is a huge visual difference between the texture and the black displayed on the screen, which cannot provide an immersive experience and results in a poor user experience. If the secondary screen is not in use but is kept in a bright state, it will also waste power.

[0003] Summary of the Invention

[0004] The purpose of this disclosure is to provide a glass cover, a display device, a vehicle, and a method for manufacturing a glass cover, which can reduce or even avoid the visual difference between the screen and the bezel, improve the aesthetics and visual effect of the screen and the bezel, optimize the user experience, and at least partially solve the aforementioned technical problems.

[0005] To achieve the above objectives, a first aspect of this disclosure provides a glass cover for covering a screen of a display device, the screen including a first screen, the glass cover comprising: a transparent glass substrate having a first area for covering the first screen; and a pattern layer disposed on one side of the glass substrate and at least covering the first area, the pattern layer having a pattern and a light-transmitting area including a plurality of light-transmitting portions; the pattern layer is used to display the pattern when the first screen is off, and to display the pattern and display an image of the first screen displayed through the light-transmitting area and the pattern layer when the first screen is on.

[0006] Optionally, the glass substrate has a decorative area and a second area covering the second screen. The decorative area includes an intermediate area located between the first area and the second area and a peripheral area surrounding the first area and the second area. The glass cover also includes a gradient pattern layer that covers the intermediate area or covers the intermediate area and at least part of the peripheral area. The gradient pattern layer has a gradient pattern of the same color scheme, and the pattern layer covers the gradient pattern layer.

[0007] Optionally, the pattern layer is provided with a plurality of light-transmitting holes, and the light-transmitting holes are filled with transparent oil that forms the light-transmitting portion.

[0008] Optionally, the glass cover further includes: a first transparent oil layer for covering the first region and the gradient pattern layer, the first transparent oil layer being located on the side of the pattern layer facing the glass substrate; at least one first ink layer covering the side of the pattern layer opposite to the first transparent oil layer; and a second transparent oil layer covering the side of the at least one first ink layer opposite to the pattern layer, the light-transmitting hole penetrating the pattern layer and the at least one first ink layer; and at least one second ink layer covering the side of the second transparent oil layer opposite to the at least one first ink layer.

[0009] A second aspect of this disclosure provides a display device, the display device including the glass cover plate described in the above-mentioned alternative.

[0010] Optionally, the display device includes a first screen and a second screen.

[0011] A third aspect of this disclosure provides a vehicle that includes the display device described in the above-mentioned alternative.

[0012] A fourth aspect of this disclosure provides a method for manufacturing a glass cover plate for covering a screen of a display device, the screen including a first screen. The method includes: providing a transparent glass substrate having a first area for covering the first screen; and providing a pattern layer to cover the first area on one side of the glass substrate, the pattern layer having a pattern and a light-transmitting area including a plurality of light-transmitting portions, such that the pattern layer is used to display the pattern when the first screen is off, and to display the pattern and an image displayed on the first screen through the light-transmitting area via the pattern layer when the first screen is on.

[0013] Optionally, the glass substrate has a decorative area and a second area covering the second screen, the decorative area including an intermediate area between the first area and the second area and a peripheral area surrounding the first area and the second area; before setting the pattern layer, the method further includes: setting a gradient pattern layer to cover the intermediate area or cover the intermediate area and at least part of the peripheral area, the gradient pattern layer having a gradient pattern of the same color scheme; setting the pattern layer includes: covering the gradient pattern layer and the first area with the pattern layer.

[0014] Optionally, setting the gradient pattern layer includes: setting a first transparent oil layer to cover the gradient pattern layer and the first region; setting the pattern layer having the pattern to cover the side of the first transparent oil layer away from the glass substrate; setting at least one first ink layer to cover the side of the pattern layer away from the first transparent oil layer; setting a plurality of light-transmitting holes to penetrate at least the at least one first ink layer and the pattern layer; filling the plurality of light-transmitting holes with transparent oil to form the light-transmitting portion, and forming a second transparent oil layer covering the side of the at least one first ink layer away from the pattern layer with the transparent oil.

[0015] With the above-mentioned technical solution, namely the glass cover provided in this disclosure, when the display screen is covered by the glass cover and the first screen is in a screen-off state, the pattern on the pattern layer will be projected into the human eye. When the first screen is in a screen-on state, the image displayed on the first screen will pass through the light-transmitting area and through the pattern layer, and be projected into the human eye together with the pattern on the pattern layer. Under this projection method, when the first screen is in a screen-off state, it will not only show the black of the screen itself, but can show the pattern of the pattern layer. The pattern can be designed according to the requirements. For example, when the glass cover is used for a central control screen, the pattern layer can be designed to be the same as or similar to the pattern of the frame area, which can reduce the large visual effect difference between the screen and the frame, improve the aesthetics and visual effect of the screen and the frame, improve the user experience, and when the screen (e.g., the secondary screen) is not in use, the screen can be turned off, so as to save power and maintain the user's immersive experience.

Detailed Implementation

[0034] The specific embodiments of this disclosure 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 this disclosure.

[0035] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" refer to the inner and outer contours of the structure or component itself; "first" and "second" are used to distinguish one element from another and do not have sequentiality or importance; furthermore, the same reference numerals in different reference drawings denote the same element.

[0036] A first aspect of this disclosure provides a glass cover, as shown in Figures 1 to 14, for covering the screen of a display device, the screen including a first screen, the glass cover including a transparent glass substrate 2 and a pattern layer 3, the transparent glass substrate 2 having a first region 210 for covering the first screen; the pattern layer 3 is disposed on one side of the glass substrate 2 and at least covers the first region 210, the pattern layer 3 having a pattern 310 and a light-transmitting region 320 including a plurality of light-transmitting portions; the pattern layer 3 is used to display the pattern 310 when the first screen is off, and to display the pattern 310 and the image displayed on the first screen through the light-transmitting region 320 via the pattern layer 3 when the first screen is on.

[0037] In this way, when the display screen is covered by the glass cover provided in this disclosure and the first screen is in a screen-off state, the pattern 310 on the pattern layer 3 will be projected into the viewer's eyes. When the first screen is in a screen-on state, the image displayed on the first screen will pass through the light-transmitting area 320 and through the pattern layer 3, and be projected into the viewer's eyes together with the pattern 310 on the pattern layer 3. Under this projection method, when the first screen is in a screen-off state, it will not only show the black of the screen itself, but can show the pattern of the pattern layer. The pattern can be designed according to the requirements. For example, when the glass cover is used for a central control screen, the pattern layer 3 can be designed to have the same or similar pattern as the border area, which can reduce the large visual effect difference between the screen and the border, improve the aesthetics and visual effect of the screen and the border, improve the user experience, and when the screen (e.g., the secondary screen) is not in use, the screen can be turned off, so as to save power and maintain the user's immersive experience.

[0038] It should be noted that the first screen mentioned in the above embodiments can be any screen capable of displaying patterns. For example, the first screen can be the main screen or secondary screen on a vehicle, or the display screen of an electronic device such as a computer. This disclosure does not make any specific limitations in this regard.

[0039] In one exemplary application scenario, the first screen can be a secondary screen on a vehicle. When the secondary screen is off, it can display the pattern on pattern layer 3. When the secondary screen is on, it can display pattern 310 and the image displayed on the secondary screen. The pattern can be designed according to actual needs. For example, pattern 310 can be the texture of some materials, such as wood grain, leather grain, cloth stripes, jade grain, bamboo grain, antique pattern, etc., or it can be some traditional cultural patterns, such as auspicious cloud pattern, phoenix pattern, ruyi pattern, swastika pattern, winding water pattern, etc., or it can be some animal pattern, such as dragon pattern, phoenix pattern, bird pattern, beast pattern, etc. This disclosure does not make specific limitations in this regard.

[0040] To facilitate understanding of the above effects by those skilled in the art, reference can be made to Figures 13 and 14, which exemplarily illustrate an example where pattern 310 is a wood grain pattern. In Figure 14, the first screen is on, and the wood grain pattern and the image displayed on the first screen (e.g., an image of a goldfish) are simultaneously displayed on the glass cover. Figure 13 exemplarily illustrates an implementation where pattern layer 3 covers the middle area 410 and the outer area 420 (described below), where the middle area 410 and the outer area 420 can be understood as the border area mentioned in the background of this disclosure. In this arrangement, when the first screen is in a sleep state, it displays the original color of pattern 310, such as the wood grain effect shown in Figure 13. At this time, the display area and border of the first screen are all consistent with the wood grain pattern. When the first screen is in a light-on state, pattern 310 and the image displayed on the first screen will be displayed together. At this time, the image or dynamic effect displayed by the first screen through its own illumination will pass through the pattern layer 3 through the light-transmitting area 320 and be projected into the human eye. As shown in Figure 8, in the embodiment given in Figure 8, the direction of arrow X can represent the direction of the light illuminating the first screen itself. During the process of the light shining along the direction of arrow X, it will pass through the pattern layer 3 and then shine on the glass substrate 2, and finally be projected into the human eye, thus achieving the effect shown in Figure 14, to display the image or dynamic effect and the texture of the wood grain pattern.

[0041] Furthermore, Figure 5 illustrates a wood grain-like pattern by way of lines, and Figure 5 illustrates that the spacing between the wood grains can be used to create a light-transmitting area 320, and the light-transmitting area 320 may include a plurality of light-transmitting parts. This disclosure does not specifically limit the size and shape of the light-transmitting parts, as long as they can transmit the image displayed from the first screen.

[0042] It should be noted that the multiple textures mentioned in the above embodiments will not cause excessive screen breakage when the first screen is on. For example, the length of a single texture along the vertical direction of the first screen can be 0.01mm, and the distance between any two adjacent textures can also be 0.01mm, that is, the interval between individual light-transmitting parts is also 0.01mm. Under this arrangement, the gaps formed between multiple textures, that is, the gaps of the light-transmitting holes 330 (described below) of the light-transmitting area 320, will not be directly observed by the naked eye. Under this arrangement, it can satisfy the requirement of displaying the texture of pattern 310 when the first screen is off, and can also smoothly display the picture or dynamic effects when the first screen is on.

[0043] In some embodiments, referring to Figures 1 to 14, the glass substrate 2 has a decorative region 4 and a second region 220 covering the second screen. The decorative region 4 includes an intermediate region 410 located between the first region 210 and the second region 220, and an outer region 420 surrounding the first region 210 and the second region 220. The glass cover also includes a gradient pattern layer 6, which covers the intermediate region 410 or covers the intermediate region 410 and at least part of the outer region 420. The gradient pattern layer 6 has a gradient pattern of the same color scheme, and a pattern layer 3 covers the gradient pattern layer 6. In this way, the gradient pattern layer 6 can further enhance the aesthetic appeal of the gradient transition of the glass cover, as shown in Figures 3, 9, and 13. When there are multiple screens, in order to reduce the large visual contrast caused by color differences between different screens, a gradient pattern layer 6 can be set between multiple screens. In the embodiment shown in Figure 9, this disclosure allows for a smoother color transition between the first and second screens by setting a gradient pattern layer 6 between the first and second screens. Taking a glass cover applied to a central control screen as an example, when the first screen is the secondary screen and the second screen is the primary screen, and both the first and second screens are off, the second screen displays black. The first screen, covered by the pattern layer 3, displays the pattern on the pattern layer 3. Therefore, to avoid the color difference between the first and second screens affecting the user experience, the aforementioned gradient pattern layer 6 can be set. For example, as shown in Figure 9, the gradient pattern layer 6 can adopt a black-and-white gradient transition, that is, the transition from the second screen to the first screen can be black-dark gray-light gray-white. Thus, the visual effect given to the user is that the color changes from dark to light when transitioning from the second screen to the first screen. Combined with the pattern layer 3 covering the first screen, the effect shown in Figure 13 can be displayed, that is, the color of the pattern from the second screen to the first screen gradually changes from dark to light, thereby improving the aesthetic effect of the transition between multiple screens and optimizing the user experience. Therefore, the display effect of overlapping gradient pattern layer 6 and pattern layer 3 further significantly optimizes the user experience.

[0044] Furthermore, this disclosure is not limited to the arrangement of the gradient pattern layer 6 described above. For example, as shown in Figure 9, a gradient pattern layer 6 facing other directions can also be set in the outer area 420 of the second screen (which may be the main screen). In this arrangement, the visual coordination between the border of the second screen and the surrounding interior decoration can be improved, and the gradient transition effect can be enhanced.

[0045] Furthermore, to make the transition between the first and second screens smoother and reduce visual impact, the gradient pattern layer 6, in the direction from the second screen towards the first screen, can use gradient lines to create a transition at the end near the first screen. For example, Figures 10 and 11 show the implementation effects of two different gradient methods. In embodiments not shown, the gradient effect and gradient amplitude can be flexibly changed according to the actual situation. Moreover, the above-mentioned gradient effect is mainly reflected in the unequal spacing design between the lines, such as the unequal distance between multiple vertical lines in Figures 10 and 11. The distance can be designed using mathematical function equations, such as: Y i～n =a+kX i～n , where Y i～n This can represent the distance from the i-th to the n-th vertical line, in millimeters, where n is a positive integer greater than i, 'a' can be the initial equidistant distance and any suitable value, and 'k' is a scaling factor that can be any number between 0 and 100. i～n It can represent the Y of the previous vertical line (i～n-1) The value of is obtained by analogy, and the values ​​of multiple unequal distances can be calculated according to the above formula.

[0046] In some embodiments, referring to Figures 1 to 14, the pattern layer 3 is provided with a plurality of light-transmitting holes 330, and the light-transmitting holes 330 are filled with transparent oil 340 forming light-transmitting portions. In this way, when the first screen is in a bright state, the transparent oil 340 can project the image or dynamic effect outward through the light-transmitting portion, thus playing a role in assisting in displaying the image. Referring to Figure 5, the transparent oil 340 can be evenly arranged within the plurality of light-transmitting holes 330 to project the image outward more clearly.

[0047] It should be noted that in the above-described embodiments, namely the embodiment shown in Figure 5, there are multiple light-transmitting holes 330 and they are distributed in stripes at intervals on the pattern layer 3. However, this disclosure is not limited to this. In the case that the image of the first screen can be clearly projected to the outside, the light-transmitting holes 330 can also be circular, rectangular or other arbitrarily suitable irregular hole structures. This disclosure does not make any specific limitation in this regard.

[0048] In some embodiments, referring to Figures 1 to 14, the glass cover further includes a first transparent oil layer 710, at least one first ink layer 720, a second transparent oil layer 810, and at least one second ink layer 820. The first transparent oil layer 710 is used to cover the first region 210 and the gradient pattern layer 6. The first transparent oil layer 710 is located on the side of the pattern layer 3 facing the glass substrate 2. At least one first ink layer 720 covers the side of the gradient pattern layer 6 away from the first transparent oil layer 710. The second transparent oil layer 810 covers the side of the at least one first ink layer 720 away from the pattern layer 3. A light-transmitting hole 330 penetrates the pattern layer 3 and the at least one first ink layer 720. At least one second ink layer 820 covers the side of the second transparent oil layer 810 away from the at least one first ink layer 720.In this way, both the first ink layer 720 and the second ink layer 820 can be combined with inks of different colors and, when combined with the first screen and / or the second screen, can present a variety of visual effects. For example, they can increase the contrast of the screen display, improve brightness, or achieve other specific optical effects, thereby further enhancing the overall aesthetics of the glass cover. Furthermore, the first ink layer 720 and the second ink layer 820 are not limited to a single layer; they can be composed of multiple layers of different colors. After combining multiple layers of the first ink layer 720 or multiple layers of the second ink layer 820, a lamination process is usually required. The first ink layer 720 and the second ink layer 820 after lamination can also provide some protection for the screen. The first transparent oil layer 710 and the second transparent oil layer 810 can each cover the first ink layer 720 and the second ink layer 820 with a protective film to protect the underlying first ink layer 720 and the second ink layer 820. This prevents contamination of the glass substrate 2 (e.g., dust, grease, moisture, or ultraviolet radiation causing corrosion) from affecting the glass substrate 2. The penetration of oil into the first ink layer 720 or the second ink layer 820, causing damage to the ink, can be understood as follows: In the embodiment shown in Figure 8, when the surface of the glass substrate 2 does not have an oil-resistant structure (e.g., an oleophobic layer), when oil adheres to the surface of the glass substrate 2 away from the first transparent oil layer 710, the oil will corrode the glass substrate 2, and the oil will gradually penetrate through the glass substrate 2 and the gradient pattern layer 6 and move towards the first ink layer 720. During the movement of the oil, when the oil flows to the first transparent oil layer 710, the oil will be stopped by the first transparent oil layer 710. This prevents oil from continuing to damage the ink in the first ink layer 720. If oil accidentally penetrates the first transparent oil layer 710 and damages the ink in the first ink layer 720, the second transparent oil layer 810 can protect the second ink layer 820 to prevent oil from penetrating the second transparent oil layer 810 and continuing to damage the second ink layer 820. Furthermore, the first ink layer 720 and the second ink layer 820 can also increase the optical performance of the screen, such as improving transparency and reducing glare and reflection, so that the patterns projected on the first screen and the second screen can be displayed more clearly.

[0049] It should be noted that the number of layers of the first ink layer 720 and the second ink layer 820 can be selected appropriately based on the actual situation. For example, referring to Figure 8, the first ink layer 720 is located on the side of the pattern layer 3 away from the first transparent ink layer 710, and the number of layers can be three, with each of the three first ink layers 720 having a different color. The second ink layer 820 is located on the side of the second transparent ink layer 810 away from the first ink layer 720, and the number of layers of the second ink layer 820 can be two, with each of the two layers having a different color. In this arrangement, the second transparent ink layer 810 can cover the two second ink layers 820. The first transparent oil layer 710 serves a protective function, protecting the three first ink layers 720. This means that when the glass cover is finished and in use, the first transparent oil layer 710 prevents oil from penetrating the glass substrate 2 and the gradient pattern layer 6 and entering the first ink layer 720, thus preventing damage to the ink printed on the first ink layer 720. The second transparent oil layer 810, on the other hand, protects the second ink layer 820 from further damage if oil accidentally penetrates the first transparent oil layer 710 and damages the first ink layer 720.

[0050] When printing the ink layers in the above embodiments, such as the gradient pattern layer 6, pattern layer 3, first ink layer 720, and second ink layer 820, a screen mesh of 350-500# (a specific unit of measurement for mesh size in screen printing) can be used for printing. The thickness of the ink in a single layer can be reasonably selected within the range of 1-5μm. After printing, the ink needs to be dried and cured. The drying and curing temperature can be reasonably selected within the range of 120℃-180℃, and the time can be reasonably selected within the range of 5-50 minutes.

[0051] After the above-mentioned multi-layer ink printing is completed, the glass cover can also be printed with positioning lines. For example, as shown in Figure 8, the glass cover also includes a positioning line layer 830 located on the second ink layer 820 away from the second transparent ink layer 810. After the above-mentioned ink printing, the positioning lines are printed to form the positioning line layer 830, which can be used for the bonding process. That is, it can be understood as bonding the transparent glass substrate 2 with the first screen or the second screen to complete the bonding process. The positioning lines on the positioning line layer 830 can improve the accuracy of bonding the glass substrate 2 with the first screen or the second screen to ensure that it can meet the production requirements before leaving the factory.

[0052] After the positioning line layer 830 is arranged, the glass cover can be treated with anti-glare, anti-reflection and anti-fingerprint in sequence before packaging and shipping. Referring to Figure 8, the glass cover can also include an anti-glare layer 840, an anti-reflection layer 850 and an anti-fingerprint layer 860 located on the side of the glass substrate 2 away from the gradient pattern layer 6. When treating the first screen or the second screen with anti-glare, one or more of the processes commonly used in the prior art, such as spraying, etching, coating and imprinting, can be used to complete the production of the anti-glare layer 840. When treating the first screen or the second screen with anti-reflection and anti-fingerprint, processes commonly used in the prior art, such as evaporation or sputtering, can be used to complete the production of the anti-reflection layer 850 and the anti-fingerprint layer 860. Since the above methods can usually be used to process glass in the prior art, this disclosure will not elaborate further.

[0053] A second aspect of this disclosure provides a display device including the glass cover plate mentioned in the above-described embodiments, and the glass cover plate possesses all the beneficial effects of the above-described embodiments. In this disclosure, the display device can be any structure that can apply the glass cover plate. For example, the display device can be a liquid crystal display (LCD), a light-emitting diode display (LED), a projector, a tablet computer, or a mobile phone, etc. This disclosure does not specifically limit it. When the above-described display device applies the glass cover plate structure, the visual effect difference between the screen and the frame can be reduced, which can improve the aesthetics and visual effect of the screen and the frame, so as to provide users with a more immersive experience.

[0054] In some embodiments, the display device is the vehicle's central control screen, which may include a first screen and a second screen, i.e., a combination of multiple screens as illustrated in Figure 9. For example, the main and secondary screen structure in the vehicle interior can apply the above-mentioned combination of the first screen and the second screen, i.e., the first screen is the secondary screen of the vehicle and the second screen is the main screen of the vehicle. Furthermore, the positional relationship between the first screen and the second screen is not limited to the arrangement shown in Figure 9, i.e., the first screen is below and the second screen is above. In embodiments not shown in the figure, the first screen and the second screen can also be connected by a left-right splicing position, i.e., the second screen can be understood as the main screen corresponding to the driver's seat, and the first screen can be the secondary screen corresponding to the passenger's seat. Furthermore, the number of the first screen and the second screen is not limited to each being a single screen as shown in the figure. The number of the first screen and the second screen can be adaptively increased or decreased according to the size of the vehicle interior space, and this disclosure does not make specific limitations in this regard.

[0055] A third aspect of this disclosure provides a vehicle that includes the display device mentioned in the above embodiments, and the display device has all the beneficial effects of the above embodiments. The vehicle can be a commercial vehicle, a truck, or a passenger car, such as a gasoline vehicle, a plug-in hybrid vehicle, a pure electric vehicle, or a hydrogen fuel cell vehicle. When the display device is applied to the above-mentioned vehicle, the human-machine interaction of the vehicle can be improved, and the vehicle's intelligence and technological effects can be enhanced.

[0056] A fourth aspect of this disclosure provides a method for manufacturing a glass cover plate, as shown in Figures 1 to 14, the glass cover plate being used to cover the screen of a display device, the screen including a first screen, the method comprising the following steps.

[0057] Step S1: Provide a transparent glass substrate 2, the glass substrate 2 having a screen for covering a display device, the screen including a first screen.

[0058] Step S3: Set a pattern layer 3 to cover a first region 210 on one side of the glass substrate 2. The pattern layer 3 has a pattern 310 and a light-transmitting region 320 including multiple light-transmitting parts, so that the pattern layer 3 is used to display the pattern 310 when the first screen is off, and to display the pattern 310 and the image displayed on the first screen through the light-transmitting region 320 via the pattern layer 3 when the first screen is on.

[0059] When the display screen is covered by the glass cover made by the above method and the first screen is in a screen-off state, the pattern 310 on the pattern layer 3 will be projected into the viewer's eyes. When the first screen is in a screen-on state, the image displayed on the first screen will pass through the light-transmitting area 320 and through the pattern layer 3, and be projected into the viewer's eyes together with the pattern 310 on the pattern layer 3. Under this projection method, the first screen will not only show the black of the screen itself when it is in a screen-off state, but can show the pattern of the pattern layer 3. The pattern can be designed according to the requirements. For example, when the glass cover is used for the central control screen, the pattern layer 3 can be designed to be the same as or similar to the pattern of the border area, which can reduce the large visual effect difference between the screen and the border, improve the aesthetics and visual effect of the screen and the border, improve the user experience, and when the screen (such as the secondary screen) is not in use, the screen can be turned off, so as to save power and maintain the user's immersive experience.

[0060] In this embodiment, the glass cover plate mentioned can be the glass cover plate provided in the first aspect of this disclosure.

[0061] For example, the glass substrate has a decorative region 4 and a second region 220 of a second screen covering the screen. The decorative region 4 includes an intermediate region 410 located between the first region 210 and the second region 220 and a peripheral region 420 surrounding the first region 210 and the second region 220.

[0062] Prior to step S3 above, the method further includes:

[0063] Step S2: Set a gradient pattern layer 6 to cover the middle area 410 or cover the middle area 410 and at least part of the outer area 420. The gradient pattern layer 6 has a gradient pattern of the same color scheme. The gradient pattern layer 6 can further enhance the aesthetic appeal of the gradient transition of the glass cover.

[0064] Based on step S2, in step S3 above, the method further includes: covering the gradient pattern layer 6 and the first region 210 with the pattern layer 3. In this way, when the first screen is in a screen-off state, the original texture of the pattern layer 3, such as the wood grain mentioned in the above embodiments, can be displayed. The wood grain can create a better visual effect with the border of the first screen. For example, when the first screen is applied to vehicle interiors, the wood grain texture can create a better visual effect with patterns in the vehicle interior that have the same wood grain texture or similar texture structure. The gradient pattern layer 6 overlaps with the pattern layer 3, giving the user the visual effect that, when transitioning from the second screen to the first screen, the color can, for example, go from dark to light. Combined with the pattern layer covering the first screen, the effect shown in Figure 13 can be displayed, that is, the color of the pattern gradually changes from dark to light from the second screen to the first screen, thereby improving the aesthetic effect of the transition between multiple screens and optimizing the user experience.

[0065] Specifically, step S3 can be implemented through the following steps, for example, step 3 includes:

[0066] Step S301: Set the first transparent oil layer 710 to cover the gradient pattern layer 6 and the first area 210;

[0067] Step S302: A pattern layer 3 with a pattern 310 is provided to cover the side of the first transparent oil layer 710 facing away from the glass substrate 2.

[0068] Step S303: Deposit at least one first ink layer 720 to cover the side of the pattern layer 3 facing away from the first transparent ink layer 710;

[0069] Step S304: Set multiple light-transmitting holes 330 to penetrate at least one first ink layer 720 and pattern layer 3;

[0070] Step S305: Fill a plurality of light-transmitting holes 330 with transparent oil 340 to form a light-transmitting part, and form a second transparent oil layer 810 covering the side of at least one first ink layer 720 opposite to the pattern layer 3 with transparent oil 340.

[0071] By combining the above methods, the first ink layer 720 and the second ink layer 820 can both be composed of inks of different colors. When combined with the first screen and / or the second screen, they can present a variety of visual effects, such as increasing screen contrast, improving brightness, or achieving other specific optical effects, thereby further enhancing the overall aesthetics of the glass cover. Furthermore, the first ink layer 720 and the second ink layer 820 are not limited to a single layer; they can be composed of multiple layers of different colors. After combining multiple layers of the first ink layer 720 or multiple layers of the second ink layer 820, a lamination process is usually required. The first ink layer 720 and the second ink layer 820 after lamination can also provide a certain degree of protection for the screen. The first transparent oil layer 710 and the second transparent oil layer 810 can respectively cover the first ink layer 720 and the second ink layer 820 with a protective film to protect the underlying first ink layer 720 and the second ink layer 820, preventing corrosion of the glass substrate 2 due to contamination (e.g., dust, grease, moisture, or ultraviolet radiation). When contaminants penetrate the first ink layer 720 or the second ink layer 820, they can damage the ink. Referring to Figure 8, in the embodiment shown in Figure 8, when the surface of the glass substrate 2 does not have an oil-resistant structure (e.g., an oleophobic layer), when oil adheres to the surface of the glass substrate 2 away from the first transparent oil layer 710, the oil will corrode the glass substrate 2. The oil will gradually penetrate the gradient pattern layer 6 and move towards the first ink layer 720. During this movement, when the oil flows to the first transparent oil layer 710, it will be blocked by the first transparent oil layer 710. This prevents oil from continuing to damage the ink in the first ink layer 720. If oil accidentally penetrates the first transparent oil layer 710 and damages the ink in the first ink layer 720, the second transparent oil layer 810 can protect the second ink layer 820 to prevent oil from penetrating the second transparent oil layer 810 and continuing to damage the second ink layer 820. Furthermore, the first ink layer 720 and the second ink layer 820 can also increase the optical performance of the screen, such as improving transparency and reducing glare and reflection, so that the patterns projected on the first screen and the second screen can be displayed more clearly.

[0072] This disclosure exemplarily describes the overall process of manufacturing the glass cover, which may include, for example, the following steps:

[0073] Referring to Figure 1, in step S1, a transparent glass substrate 2 is provided. The material of the glass substrate 2 can be transparent or partially transparent, and it has a first area 210 for covering the first screen. The prepared material is processed by any method such as wire cutting, stamping, grinding, or laser cutting to further obtain a pre-designed shape with a reinforcement expansion allowance. If a 3D three-dimensional shape is required in this step, it can also be processed by shaping processes such as injection molding, compression molding, stamping, or thermoforming. After processing, the material is placed in a 90%-100% potassium nitrate solution at 370℃-450℃ for 3-6 hours to further enhance the structural strength of the material.

[0074] In step S2, a gradient pattern layer 6 is set. The pattern of the gradient pattern layer 6 can be color-separated using digital software (Photoshop, Illustrator, CorelDRAW, etc.) to further obtain single color units of CMYK (cyan / magenta / yellow / black) and output the L*a*b standard values ​​of the colors. After mixing the pigments, dyes, resins, and other materials in appropriate proportions, materials such as paints, inks, or dyes that meet the above L*a*b standard values ​​are obtained. Film is made according to the above color separation data and the shape required by the substrate. After making the screen required for printing, the gradient pattern layer 6 can be used to cover the middle area 410 or cover the middle area 410 and at least part of the outer area 420.

[0075] In step S3, the pattern layer 3 is covered over the gradient pattern layer 6 and the first region 210. In this process, the pattern layer 3 can be set up and can be printed in sequence according to the following steps (S301 to S305).

[0076] In step S301, a first transparent oil layer 710 is set to cover the gradient pattern layer 6 and the first area 210. In this step, the structure of the first transparent oil layer 710 in Figure 8 can be completed in the manner described above, that is, the first transparent oil layer 710 is printed through a screen with a mesh size of 350-500# under the conditions of ink thickness of 1-5μm, baking temperature of 120-180℃, and time of 5-50 minutes.

[0077] In step 302, a pattern layer 3 with pattern 310 is provided to cover the side of the first transparent oil layer 710 facing away from the glass substrate. In this step, the structural layer of pattern layer 3 in FIG8 can be completed in the manner described above, that is, the pattern layer 3 is printed through a screen with a mesh size of 350-500# under the conditions of ink thickness of 1-5μm, baking temperature of 120-180℃, and time of 5-50 minutes.

[0078] In step 303, at least one first ink layer 720 is provided to cover one side of the proportional first transparent ink layer 710 of the pattern layer 3. In this step, the structure of the first ink layer 720 in FIG8 can be completed in the manner described above, that is, the pattern layer 3 is printed through a screen with a mesh size of 350-500# under the conditions of ink thickness of 1-5μm, baking temperature of 120-180℃ and time of 5-50 minutes.

[0079] In step S304, multiple light-transmitting holes 330 are provided to penetrate at least one first ink layer 720 and the pattern layer 3. During this process, an ultrafine degreasing operation can be employed, such as laser or developing, to remove the oil from the light-transmitting holes 330 of the pattern layer 3, allowing the pattern projected onto the first or second screen to pass through the multiple light-transmitting holes 330 and be displayed on the glass substrate 2.

[0080] In step S305, a plurality of light-transmitting holes 330 are filled with transparent oil 340 to form a light-transmitting portion, and a second transparent oil layer 810 is formed by the transparent oil 340 covering the side of at least one first ink layer 720 facing away from the pattern layer 3. In this step, the second transparent oil layer 810 of FIG8 can be completed in the manner described above, that is, the second transparent oil layer 810 is printed through a screen with a mesh size of 350-500# under the conditions of ink thickness of 1-5μm, baking temperature of 120-180℃, and time of 5-50 minutes.

[0081] After the first transparent ink layer 710 is printed, the second ink layer 820 can be printed on the side of the second transparent ink layer 810 away from the first ink layer 720. In this step, the structural layer of the second ink layer 820 in Figure 8 can be completed in the manner described above, that is, the second ink layer 820 is printed through a screen with a mesh size of 350-500# under the conditions of ink thickness of 1-5μm, baking temperature of 120-180℃, and time of 5-50 minutes.

[0082] After the above multi-layer ink printing is completed, the positioning lines can be printed on the glass cover. White ink can be used for printing the positioning lines, and the positioning line layer 830 can be printed using a 350-500# mesh screen as described above, under the conditions of ink thickness of 1-5μm, baking temperature of 120-180℃, and time of 5-50 minutes.

[0083] After the positioning lines are printed, the glass cover can be treated with anti-glare, anti-reflection, and anti-fingerprint agents before packaging and shipping. When treating the first or second screen with anti-glare, one or more of the processes commonly used in the prior art, such as spraying, etching, coating, and embossing, can be used to complete the production of the anti-glare layer 840. When treating the first or second screen with anti-reflection and anti-fingerprint agents, processes commonly used in the prior art, such as evaporation or sputtering, can be used to complete the production of the anti-reflection layer 850 and the anti-fingerprint layer 860. After production, the glass cover can be packaged and shipped.
