Description

Technical Field

[0001] This utility model relates to a wood grain-look glass panel, belonging to the field of display screen glass technology. Background Technology

[0002] Glass panels are commonly used in human-computer interaction (HCI) displays for visual products, such as computer and mobile phone screens, as well as in-vehicle displays in the automotive industry. With continuous societal development, users have increasingly higher expectations for the design and surface decoration of HCI products. In-mold decoration (IMD) technology, a popular glass surface treatment technique, is also frequently applied to the surface decoration of automotive interior parts and electronic product display panels to achieve a combination of aesthetics and functionality. However, the viewing area of ​​most display screens is usually visible and lacks a concealed function. The integration and unified appearance of the display screen with other components are inconsistent. This is especially true in the automotive industry, where interior parts and control systems in small cars are generally separate systems. For example, in-vehicle dashcams and central control display systems typically have independent control panels. Multiple control panels and components complicate the overall structure, limit design creativity, occupy significant space, and result in poor visual effects and aesthetics. The integration between the display screen and other components is also inadequate.

[0003] To achieve hidden and decorative textured patterns on display panels, products with decorative textured patterns are formed by printing decorative inks onto the glass panel. Existing technology involves printing a layer of ink with a decorative textured pattern, such as a wood grain or metal grain pattern, onto the surface of the glass panel. Then, a white translucent film layer is printed on top of this layer, followed by white light-blocking beacons and window printing ink layers. Finally, a black border masking ink layer is printed on the surface of the area to be shielded by the glass panel. However, this ink layer design suffers from the problem that the black border masking ink layer is directly applied from the translucent ink layer (the light-blocking beacon and window). The transition from the printed ink layer to an opaque black ink layer results in poor overall continuity. While it achieves some screen-hiding functionality, the significant color difference between the black masking ink layer and the previous ink layer leads to poor border concealment at the boundary between the window area and the masked area. This makes the border visible at the boundary, resulting in a faint border even when the screen is off. Furthermore, the single-layer structure of the black masking ink layer causes light leakage due to printing processes, leading to bright spots in the corresponding masked area during use. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a wood grain-look glass panel to solve the issues of light leakage and poor concealment of the window boundary.

[0005] The purpose of this utility model is achieved through the following technical solution: a wood grain-like glass panel, the glass panel comprising a glass substrate, the glass substrate having a viewing area and a shielding area, one side surface of the glass substrate covered with a wood grain-like ink layer, the area of ​​the glass substrate corresponding to the shielding area covered with a black ink border shielding layer, characterized in that the surface of the wood grain-like ink layer is covered with a varnish layer, the surface of the varnish layer is covered with a semi-transparent black ink layer, the surface of the black ink layer is printed with the black ink border shielding layer, and the surface of the black ink border shielding layer is printed with an opaque black ink overlay.

[0006] By printing a semi-transparent black ink layer on the surface of the varnish layer, its semi-transparent properties can effectively bridge the color difference between the varnish layer and the black ink border masking layer, achieving a smoother transition of color. This allows for a smooth transition of ink between the corresponding window area and the masking area, avoiding the problem of poor boundary connection caused by the ink suddenly changing from light to a light-blocking pure black. The addition of a semi-transparent black ink layer improves the overall coordination of the ink layer, thus achieving the advantages of effectively hiding the window display boundary and good consistency with the surrounding environment (masked area). When used as a display panel, the glass panel displays a wood grain effect when the screen is off, without showing the window border, similar to a hidden display screen, allowing the display to blend seamlessly with the surrounding wood grain texture. Simultaneously, a black ink overlay is printed on top of the black ink border masking layer. This multi-layered ink printing design effectively blocks light leaks within the black ink border masking layer area, achieving a masking effect on the corresponding glass panel area and preventing light leaks when the screen is on, thus improving the overall quality of the glass panel. Furthermore, covering the wood grain ink layer with a transparent varnish layer enhances the wood grain effect and provides support, allowing the wood grain characteristics to exhibit a better three-dimensional visual effect.

[0007] In the aforementioned wood grain glass panel, the inner circumferential edge of the black ink border masking layer is located inside the inner circumferential edge of the black ink cover layer. Essentially, there is a certain gap between the boundary of the black ink cover layer on the viewing area side and the boundary of the corresponding black ink border masking layer. Through this ink layer structure design, the inner sides of these two ink layers are staggered, avoiding boundary overlap. This prevents unnecessary unclear boundaries and affects the size of the viewing area due to repeated printing of the viewing area boundary. Consequently, it avoids affecting the boundary accuracy and quality of the viewing area when printing the ink on the black ink cover layer, ensuring the size and precision of the viewing area. Simultaneously, the gap formed between them also creates a transitional effect between the outer periphery of the viewing area and the masking area, resulting in better overall integration.

[0008] In the aforementioned wood grain glass panel, the light transmittance of the black ink layer is 4.0% to 10%. This light transmittance, combined with a better transition characteristic, results in a smoother color difference from the varnish layer side to the black ink border layer side. When this wood grain glass panel is used as a display panel, in the screen-off state, it is more conducive to achieving a completely hidden visual effect, allowing the screen's display interface and interactive functions to be hidden under the interior, achieving a display technology effect that makes the screen "disappear." When the screen is on, it can achieve the effect of displaying the window area interface.

[0009] In the aforementioned wood grain glass panel, the thickness of the transparent varnish layer is greater than the thickness of the black ink layer, with the transparent varnish layer having a thickness of 5μm to 9μm. Controlling the thickness of the transparent varnish layer to within this requirement and exceeding the thickness of the semi-transparent black ink layer allows the wood grain to exhibit a better three-dimensional effect. The relatively thin semi-transparent black ink layer primarily serves as a transition, creating a smooth transition and ensuring color harmony between the other ink layers. Furthermore, this ink layer exhibits good leveling properties. As a further preferred embodiment, the thickness of the black ink layer is preferably 2μm to 5μm.

[0010] In the aforementioned wood grain glass panel, the thickness of the wood grain ink layer is 2μm to 5μm. This is equivalent to making the thickness of the wood grain ink layer lower than that of the transparent varnish layer, which is more conducive to achieving a three-dimensional display effect.

[0011] In the aforementioned wood grain glass panel, an anti-fingerprint film is coated on the other side of the glass substrate. This enhances the overall anti-fingerprint and anti-smudge capabilities of the front surface of the glass panel.

[0012] Compared with existing technologies, this wood grain glass panel has the following advantages:

[0013] 1. This wood grain glass panel can effectively connect the color change between the varnish layer and the black ink border masking layer to achieve a smooth color transition, making the formed ink layer consistent as a whole, thereby effectively hiding the black border of the window area boundary.

[0014] 2. A layer of black ink overlay is printed on the surface of the black ink border masking layer. Through the printing of multiple layers of ink, the light leakage points of the black ink border masking layer can be effectively blocked, so that the corresponding masking area of ​​the glass panel can achieve a complete masking effect, avoiding the defect of light leakage bright spots in the masking area after the screen is turned on.

[0017] In the diagram, 1 is the glass substrate; 11 is the viewing area; 12 is the masking area; 2 is the wood grain ink layer; 3 is the varnish layer; 4 is the black ink layer; 5 is the black ink border masking layer; 6 is the black ink cover layer; and 7 is the anti-fingerprint film layer. Detailed Implementation

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] Combination Figure 1 and Figure 2 As shown, this wood grain glass panel includes a glass substrate 1, which has a viewing area 11 and a shielding area 12. Figure 1The window area 11 and the masking area 12 are illustrated with dashed lines for clarity. In actual use, the window area 11 displays the content or images played on the screen. When the screen is on, the area of ​​the window area 11 is displayed. In a further embodiment, a translucent wood grain ink layer 2 is covered on one side surface of the glass substrate 1. This layer has the characteristics of light transmission and decoration. When the screen is off, it can display the texture characteristics of wood grain. The wood grain ink layer 2 is completely covered on the side surface of the glass substrate 1, and a black ink border masking layer 5 is covered on the area of ​​the glass substrate 1 corresponding to the masking area 12. That is, the black ink border masking layer 5 is superimposed on the corresponding ink layer surface of the corresponding masking area 12. More importantly, a transparent varnish layer 3 is applied to the surface of the wood grain ink layer 2 via screen printing. A semi-transparent black ink layer 4 is then applied to the surface of the transparent varnish layer 3. A black ink border masking layer 5 is printed on the surface of the black ink layer 4, and an opaque black ink overlay layer 6 is printed on the surface of the black ink border masking layer 5. Ideally, the inner circumferential edge of the black ink border masking layer 5 should be located inside the inner circumferential edge of the black ink overlay layer 6. This creates a certain gap between the inner edges of the two ink layers, resulting in a staggered ink layer printing effect. This design offers advantages such as better avoiding the decrease in viewing area size accuracy caused by repeated printing, ensuring the quality of printing boundary dimensions, and providing a buffer zone for color differences between the inside and outside through the aforementioned spacing settings. This further facilitates the integrated concealment effect. Ideally, the light transmittance of the black ink layer 4 should be 4.0% to 10%, possessing both light transmission characteristics and a better transition buffering effect, thus enhancing the overall concealment effect. The printing of the black ink overlay 6 can also effectively prevent light leakage in the concealed area, achieving a better concealment effect. When the aforementioned wood-look glass panel is used as a display screen, the border concealment effect of the viewing area can be more effectively achieved when the screen is off. Ideally, the thickness of the transparent varnish layer should be greater than the thickness of the black ink layer, with the thickness of the transparent varnish layer being 5μm to 9μm, preferably 7μm. To improve the overall fingerprint and smudge resistance, a fingerprint film layer 7 is deposited on the other side surface of the glass substrate 1.

[0020] In a further embodiment, the thickness of the black ink layer can be 2μm to 5μm, and the thickness of the wood grain ink layer can also be 2μm to 5μm.

[0021] When used as a display panel, this wood grain glass panel effectively hides the screen when it is off, and the display panel as a whole displays the overall visual effect of wood grain texture. The boundary border between the window area 11 and the shaded area 12 is not visible. When the screen is on, the corresponding information content can be displayed in the area of ​​the corresponding window area 11.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0023] Although this document frequently uses terms such as glass substrate 1, window area 11, shielding area 12, wood grain ink layer 2, varnish layer 3, black ink layer 4, black ink border shielding layer 5, black ink cover bottom layer 6, and anti-fingerprint film layer 7, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
