[0005] Part One; and

[0006] The second segment has a second end integrally disposed on the first segment and extending from the first segment along the first direction.

[0012] Optionally, the third surface is a polished surface or a brushed surface;

[0013] The third surface has a first anodic oxide film, which is obtained by polishing or drawing the third surface.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0036] The bezel 100' is used to protect and decorate the screen of the display device. The section of the bezel 100' used for screen protection and decoration has a uniform thickness cross-section. The bezel 100' includes injection-molded decorative bezels, plastic and metal composite decorative bezels, and extruded aluminum decorative bezels, etc. Among them, extruded aluminum decorative bezels have a strong metallic texture and can achieve a narrow bezel effect, thus they are widely used. For example... Figure 1The diagram illustrates an extruded aluminum decorative frame in the prior art. The frame includes a first segment 110' and a second segment 120'. The upper end of the second segment 120' is used to protect and decorate the screen, for example, it can be positioned close to the side edge of the screen directly in front. When the width L' of the second segment 120' exceeds 10mm, the wall thickness D' of the second segment 120' needs to be greater than 0.6mm. Otherwise, during the extrusion process, the second segment 120' is susceptible to deformation due to unstable factors such as extrusion speed, temperature uniformity, and flow uniformity. Therefore, the prior art suffers from the technical problem of frame deformation during the pursuit of extremely thin and narrow bezels.

[0037] Therefore, in order to effectively solve the above-mentioned technical problems, this application proposes a border 100. Specifically, as shown in the embodiments... Figure 2 As shown, the border 100 has a first direction, including:

[0038] Part 1, Section 110; and

[0039] The second segment 120 is used to protect and decorate the screen. The second segment 120 is integrally disposed on the first segment 110 and extends from the first segment along the first direction. The second segment has a first end 121 disposed away from the first segment 110 and a second end 122 disposed on the first segment 110. The thickness D of the second segment 120 gradually narrows in the first direction, and the thickness D1 of the first end 121 is less than a preset value, while the thickness of the second end 122 is greater than a preset value.

[0040] In the technical solution of this application embodiment, the thickness of the second segment 120 is set to gradually narrow in the direction away from the first segment 110, and the thickness of the first end 121 away from the first segment 110 is less than a preset value, so as to meet the requirements of extreme adhesion between the screen and the frame 100 of the display device and achieve the requirement of extremely thin installation. At the same time, since the thickness of the second segment 120 gradually narrows in the direction away from the first segment 110, and the thickness of the second end is greater than the preset value, the risk of wavy deformation of the second segment 120 due to unstable factors such as extrusion speed, temperature uniformity and flow uniformity during the molding process can be significantly reduced.

[0041] Furthermore, in the technical solution of this application embodiment, since the thickness of the second segment 120 gradually narrows in the first direction, the thickness at the position where the second segment 120 connects with the first segment 110 is greater than the thickness of the first end 121, which has a reinforcing effect and can effectively and significantly increase the structural strength of the second segment 120 while reducing the risk of processing deformation.

[0042] It should be noted that the screen is installed in the second segment 120 at a position away from the first segment 110. In this embodiment, the frame 100 at the screen mounting position is locally thinned to meet the requirements for ultra-thin installation while reducing the risk of deformation of the frame 100.

[0043] In the above embodiments, the preset value is the value deemed necessary for achieving a narrow bezel, typically set around 0.6mm. For those skilled in the art, the preset value can also be set to be smaller than 0.6mm.

[0044] As an optional implementation of the above embodiments, the preset value is 0.6 mm. Figure 2 As shown, the thickness of the first end portion is less than 0.6 mm, and the thickness of the second end portion 122 is greater than 0.6 mm. In this embodiment, the thickness at the connection between the second segment 120 and the first segment 110 is greater than 0.6 mm, which enhances the strength of the root of the second segment 120 and reduces the probability of deformation. In this embodiment, in the first direction, the thickness of the second segment 120 gradually narrows from greater than 0.6 mm until the thickness of the first end portion 121 is less than 0.6 mm.

[0045] As an optional embodiment of the above embodiments, the thickness of the second end portion 122 is in the range of [0.8mm, 0.9mm]. Limiting the thickness of the second end portion 122 to between 0.8mm and 0.9mm can significantly improve the structural strength of the second segment 120. Furthermore, the gradual thinning also satisfies the requirement for localized thinning, reducing the risk of wavy deformation in the second segment 120 due to unstable factors such as extrusion speed, temperature uniformity, and flow uniformity during the molding process. And / or, the thickness of the first end portion 121 is in the range of [0.5mm, 0.6mm].

[0046] In some embodiments, the thickness of the second end 122 is 0.7 mm, and the thickness of the first end 121 is 0.55 mm.

[0047] In some embodiments, the thickness of the second end 122 is 0.85 mm, and the thickness of the first end 121 is 0.45 mm.

[0048] In some embodiments, the thickness of the second end 122 is 0.8 mm, and the thickness of the first end 121 is 0.5 mm.

[0049] In some embodiments, the thickness of the second end 122 is 0.9 mm, and the thickness of the first end 121 is 0.55 mm.

[0050] As an optional implementation of the above embodiments, such as Figure 2As shown, the width L of the second segment 120 in the first direction ranges from [10mm, 12mm]. In some embodiments, since the thickness of the second segment 120 gradually narrows in the direction away from the first segment 110, the risk of deformation can be effectively reduced. Therefore, the width of the second segment 120 in the first direction can be increased to more than 10mm. For example, the width of the second segment 120 in the first direction can be any value among 10mm, 10.5mm, 11mm, 11.5mm, and 12mm. The above width values ​​are the most commonly used range.

[0051] In other embodiments, the width of the second segment 120 in the first direction can be adjusted according to the actual needs of the product. For example, the width of the second segment 120 in the first direction can be 9mm or 13mm.

[0052] As an optional implementation of the above embodiments, such as Figure 2 and Figure 3 As shown, the border 100 has a second direction, which is perpendicular to the first direction. In an embodiment, a first segment 110 extends along the second direction, and a second segment 120 extends along the first direction. Figure 2 and Figure 4 As shown, the first segment 110 has a first surface 111 in the first direction, and the second segment 120 has a second surface 123 and a third surface 124 disposed opposite each other in the second direction. In an embodiment, the second segment 120 is disposed on the first surface 111 and extends away from the surface of the first surface 111 along the first direction to form a first end portion 121. The second end portion 122 of the second segment 120 is disposed on the first surface 111. In an embodiment, the first surface 111 and the second surface 123 are used to define the mounting space of the screen. The first surface 111 is perpendicular to the second surface 123, and the angle α between the third surface 124 and the extended surface of the first surface 111 ranges from 90° to 92°.

[0053] It should be noted that the perpendicularity of the first surface 111 to the second surface 123 can be understood as the first surface 111 and the second surface 123 meeting the perpendicularity requirement, and the perpendicularity is set according to the specific product requirements; that is, the included angle β between the first surface 111 and the second surface 123 is 90°, and a certain error is allowed.

[0054] It should be noted that the angle between the third surface 124 and the first surface 111 ranges from 90° to 92°. That is, in the direction away from the first segment 110, the third surface 124 gradually approaches the second surface 123, thereby making the second segment 120 gradually narrower, so as to define the narrowest thickness at the first end 121. In the embodiment, the angle α between the third surface 124 and the first surface 111 can be 90.5°, 91°, 91.5° or 92°.

[0055] In the above embodiments, the second surface 123, the first surface 111, and the third surface 124 are typically planar. In the embodiments of this application, the border 100 has a significantly reduced risk of deformation, and the second surface 123, the first surface 111, and the third surface 124 all possess reliable flatness.

[0056] As an optional embodiment of the above embodiments, the third surface 124 is a polished surface or a brushed surface. The third surface 124 has a first anodic oxide film, which is obtained after polishing or brushing the third surface 124. The third surface 124 also has a first ink layer, which is applied to the third surface 124 after the first anodic oxide film is formed.

[0057] In this embodiment, the frame 100 is manufactured using an aluminum extrusion process. An aluminum ingot is pre-formed into a profile using an extruder according to a corresponding die, and then the profile is cut to create a pre-formed frame 100. The cross-section of this pre-formed product has the following characteristics: Figure 2 Or such as Figure 3 The shape shown. Then the third surface 124 of the preform is polished or brushed to make the third surface 124 a polished surface or a brushed surface; then anodizing is performed on the brushed surface or polished surface to form a first anodized film on the third surface 124; then a first ink layer is printed on the third surface 124.

[0058] In this embodiment, the thickness of the first anodic oxide film is 6-15 μm, and the thickness of the first ink layer is 8-15 μm. In this embodiment, the first ink layer can be a high-gloss black ink layer to match the appearance color of the screen.

[0059] In this embodiment, after printing the first ink layer on the third surface 124, the forming process of the frame 100 further includes: pre-baking the pre-printed product using a tunnel oven at a temperature of 50-60°C for 5-8 minutes, and inspecting the appearance after pre-baking; printing a logo by screen printing or pad printing a light-colored logo on the first ink layer of the third surface 124; and high-temperature baking and curing by baking and curing the workpiece with the logo printed using a tunnel oven at a temperature of 120-160°C for 10-15 minutes to achieve complete curing of the ink layer on the third surface 124 and the logo ink layer.

[0060] As an optional implementation of the above embodiments, such as Figure 4 and Figure 5 As shown, the first segment 110 also has a fourth surface 112 in the second direction; the distance H between the fourth surface 112 and the third surface 124 in the second direction ranges from [0, 0.3 mm]. Here, the distance is understood as the spacing between the second end and the fourth surface. Setting the distance between the fourth surface 112 and the third surface 124 to less than or equal to 0.3 mm is beneficial for ink printing on the second end 122, facilitating complete adhesion of the screen to the third surface 124, and preventing the screen from failing to adhere tightly to the printing surface (especially the third surface 124) due to a large distance, thus affecting ink penetration and causing uneven boundary lines.

[0061] In some embodiments, such as Figure 2 , 3 As shown in Figure 5, the distance between the fourth surface 112 and the third surface 124 is 0, which can be interpreted as the fourth surface 112 and the third surface 124 being directly connected and having no distance in the second direction.

[0062] In some embodiments, such as Figure 4 As shown, the distance between the fourth surface 112 and the third surface 124 is greater than 0 and less than or equal to 0.3 mm, which can be understood as the fourth surface 112 and the third surface 124 having a distance in the second direction. In this embodiment, the middle frame of this structure has a three-dimensional visual effect.

[0063] As an optional embodiment of the above embodiments, the fourth surface 112 is a brushed surface; the fourth surface 112 has a second anodic oxide film, which is obtained after the fourth surface 112 is brushed; the fourth surface 112 also has a second ink layer, which is applied to the fourth surface 112 after the second anodic oxide film is formed. The second ink layer is a different color from the first ink layer.

[0064] Combination Figure 4As shown, taking a structure where the distance between the fourth surface 112 and the third surface 124 is greater than 0 and less than or equal to 0.3 mm as an example, the manufacturing process of the frame 100 of this structure is introduced:

[0065] The frame 100 is manufactured using an aluminum extrusion process. An aluminum ingot is pre-formed into a profile using an extruder according to a corresponding die, and then the profile is cut to create a pre-formed frame 100. The cross-section of this pre-formed product has the following characteristics: Figure 3 The shape shown is then applied. After grinding the preform, the third surface 124 is polished to make it a polished surface. Then, a masking tool is used to mask the polished surface. Finally, the fourth surface 112 is brushed to make it a brushed surface.

[0066] Anodizing is performed on the brushed and polished surfaces to form a first anodic oxide film and a second anodic oxide film on the third surface 124 and the fourth surface 112, respectively. Then, a first ink layer is printed on the third surface 124, and a second ink layer is printed on the fourth surface 112. The first ink layer is a black ink layer, and the second ink layer is a light-colored ink layer. This ensures that the third surface 124 matches the screen color, and the fourth surface 112 has a brushed light-colored anodized effect to match the aluminum alloy frame in the display device.

[0067] The frame 100 made using this process is more economical and reduces costs compared to technical solutions that use two or more anodizing processes.

[0068] In this embodiment, after printing the first ink layer on the third surface 124 and the second ink layer on the fourth surface 112, the forming process of the frame 100 further includes: pre-baking the pre-printed product using a tunnel oven at a temperature of 50-60°C for 5-8 minutes, and inspecting the appearance after pre-baking; printing a logo by screen printing or pad printing a light-colored logo on the first ink layer of the third surface 124; and high-temperature baking and curing by baking and curing the workpiece with the logo printed using a tunnel oven at a temperature of 120-160°C for 10-15 minutes to achieve complete curing of the ink layer on the third surface 124 and the logo ink layer.

[0069] As an optional implementation of the above embodiments, such as Figure 5As shown, the first segment 110 further has a fifth surface 113 in the second direction, the fifth surface 113 being connected to the end of the fourth surface 112 away from the third surface 124; the fifth surface 113 and the fourth surface 112 are inclined relative to each other. The fifth surface 113 is a brushed surface, and the fifth surface 113 has a third anodic oxide film, which is obtained after brushing the fifth surface 113. The fifth surface 113 also has a third ink layer, which is formed on the fifth surface 113 after the third anodic oxide film is formed. The third ink layer is a different color from the first ink layer.

[0070] Combination Figure 5 As shown, the forming process of the frame 100 is described with the distance between the third surface 124 and the fourth surface 112 being 0. In this embodiment, the third surface 124 and the fourth surface 112 can be regarded as a single surface.

[0071] The frame 100 is manufactured using an aluminum extrusion process. An aluminum ingot is pre-formed into a profile using an extruder according to a corresponding die, and then the profile is cut to create a pre-formed frame 100. The cross-section of this pre-formed product has the following characteristics: Figure 3 The shape shown is then polished. The third surface 124 and the fourth surface 112 are then polished to make them polished surfaces. The polished surfaces are then masked using a masking tool. Finally, the fifth surface 113 is brushed to make it a brushed surface.

[0072] Anodizing is performed on the brushed and polished surfaces to form a first anodic oxide film, a second anodic oxide film, and a third anodic oxide film on the third surface 124, the fourth surface 112, and the fifth surface 113, respectively. Then, a first ink layer is printed on the third surface 124, a second ink layer is printed on the fourth surface 112, and a third ink layer is printed on the fifth surface 113. The first and second ink layers are black ink layers, and the third ink layer is a light-colored ink layer. This ensures that the third surface 124 and the fourth surface 112 match the screen color, while the fifth surface 113 has a brushed light-colored anodized effect to match the aluminum alloy frame in the display device.

[0073] In this embodiment, after printing the first ink layer on the third surface 124, the second ink layer on the fourth surface 112, and the second ink layer on the fifth surface 113, the forming process of the frame 100 further includes: pre-baking the pre-printed product using a tunnel oven at a temperature of 50-60°C for 5-8 minutes, and inspecting the appearance after pre-baking; printing a logo by screen printing or pad printing a light-colored logo on the first ink layer of the third surface 124; and high-temperature baking and curing by baking and curing the workpiece with the logo printed using a tunnel oven at a temperature of 120-160°C for 10-15 minutes to achieve complete curing of the ink layer on the third surface 124 and the logo ink layer.

[0074] In the embodiment, the widths of both the fifth surface 113 and the fourth surface 112 are configured to be at least 3 mm to meet printing requirements.

[0075] In the embodiments, the thickness of the first anodic oxide film, the second anodic oxide film, and the third anodic oxide film can be 6 to 15 μm; the thickness of the first ink layer, the second ink layer, and the third ink layer can be 8 to 15 μm.

[0076] In some embodiments proposed in this application, the frame 100 has an integrated dual-effect appearance. The present invention combines wire drawing, polishing, anodizing and printing processes to achieve an integrated dual-color effect. Compared with the complex process of one-time anodizing + two-time anodizing, the production process of the frame 100 in this application is simple, efficient and lower in cost.

[0077] Furthermore, the printing process in this invention differs from traditional printing. It employs a process of first printing black ink on the large surface (third surface 124), then pre-baking at a low temperature, followed by printing a light-colored logo, and finally performing a one-piece high-temperature curing process, achieving a unified dual-effect appearance. This process uses low-temperature pre-baking after printing on the large surface (third surface 124). On the one hand, because the ink is not fully cured, defects can be easily detected and reworked promptly, avoiding the difficulties of ink removal and rework after full high-temperature curing; on the other hand, it enhances the adhesion between the light-colored logo ink layer and the black ink layer. Furthermore, the low-temperature pre-baking process saves energy and reduces energy loss.

[0079] screen; and

[0080] The border as described in one of the previous embodiments is used to protect and decorate the screen.

[0081] The specific structure of the border is as described in the above embodiments.

[0082] In this embodiment, the display device includes, but is not limited to, TVs, commercial all-in-one displays, and smart educational machines.

[0083] The above description is merely an optional embodiment of this application and does not limit the patent scope of this application.
