[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] Currently, flat-screen TVs, LCD TVs, and LCD monitors are widely used in people's daily lives. Taking LCD TVs as an example, as an indispensable home appliance for family entertainment, people often pay attention to the appearance and price of LCD TVs when purchasing or using them. The front bezel of the display device, as part of the LCD TV, naturally receives considerable attention.

[0033] In related technologies, ultra-thin front bezels, extremely narrow front bezels, and borderless designs have become the industry mainstream. Because the manufacturing process of the front bezel for display devices is relatively simple, it is often not aesthetically pleasing; to make the front bezel of a display device more refined, complex manufacturing processes are often required, leading to increased production costs.

[0034] The current mainstream design involves the front frame and decorative panel being independent structures. To avoid gaps between the front frame and decorative panel, they need to be glued together with double-sided tape. Since the decorative panel is made of stainless steel sheet, and the stainless steel sheet is supplied in an L-shaped strip, processing it requires the development of a separate mold for stamping, increasing both cost and manufacturing complexity.

[0035] Therefore, this application provides a method for manufacturing a front frame of a display device, a front frame of a display device, and a display device. This method for manufacturing the front frame of a display device can efficiently and cost-effectively produce the front frame. The method for manufacturing the front frame of a display device in this application can save on stainless steel sheet materials, molds, adhesive strips, etc., used in the front frame of a display device in related technologies. It has a simple structure, is easy to implement, has a high yield, and is conducive to production. A detailed analysis is provided below with reference to the accompanying drawings.

[0036] Please see Figures 1 to 4 , Figure 1 This is a schematic flowchart illustrating the method for manufacturing the front frame of the display device according to an embodiment of this application. Figure 2 This is a schematic diagram of the front frame of the display device provided in an embodiment of this application. Figure 3 This is a schematic flowchart illustrating the manufacturing process of the front frame of the display device provided in an embodiment of this application. Figure 4 This is a schematic diagram of the structure of the display device provided in the embodiments of this application.

[0037] This application provides a method for manufacturing a front frame 10 of a display device. The method for manufacturing the front frame 10 of the display device includes the following steps.

[0038] S100, provides a front frame body 11.

[0039] S200. Use a knife 20 to scrape and fold the surface of the front frame body 11 to form a decorative piece 12.

[0040] The front frame body 11 and the decorative piece 12 enclose a receiving space 13, which is used to accommodate the screen assembly 30. The front frame body 11 is made of materials such as aluminum alloy and magnesium alloy, and is manufactured by injection molding or extrusion molding. The front frame body 11 is used to fix to the back panel of the display device 1.

[0041] The cutting tool 20 can fold from the middle of the front frame body 11 towards the edge, thereby folding out a thin sheet to form a decorative piece 12. The length L2 of the front frame body 11 is greater than the length L1 of the decorative piece 12. The decorative piece 12 is a rectangular structure with decorative color. After the front frame body 11 is assembled with the back panel of the display device 1 to form the display device 1, the decorative piece 12 is located in the non-display area of ​​the front display screen of the display device 1.

[0042] The decorative piece 12 forms a preset angle with the front frame body 11, thereby enclosing and forming a receiving space 13, which is used to accommodate the screen assembly 30. The screen assembly 30 can be a screen body, a backlight module, etc.

[0043] The present application provides a method for manufacturing a display device front frame 10, the display device front frame 10, and a display device 1. In this method, the decorative piece 12 is formed simply by using a cutting tool 20 to fold and bend the surface of the front frame body 11. The front frame body 11 and the decorative piece 12 enclose a receiving space 13, which in turn accommodates the screen assembly 30. Therefore, this method for manufacturing the display device front frame 10 can efficiently and cost-effectively manufacture the display device front frame 10.

[0044] Please see Figure 5 , Figure 5 for Figure 4 A partial enlarged view at point A. In some embodiments, after forming the decorative piece 12, the method for preparing the front frame 10 of the display device further includes coating the side of the decorative piece 12 away from the receiving space 13 with black ink, that is, the non-display area of ​​the front display screen of the display device 1 is black. When the display device 1 is in a screen-off state, the color of the decorative piece 12 is close to the color of the display screen, thereby achieving a borderless display effect. The coating of the decorative piece 12 with black ink away from the receiving space 13 can be done by spraying or printing, such as screen printing.

[0045] Please see Figure 6 , Figure 6 This is a schematic diagram of the structure of a cutting tool provided in an embodiment of this application. In some embodiments, the cutting tool 20 has a wedge-shaped structure. The wedge-shaped structure has a bottom surface 21, an inclined surface 22, a first side surface 23, a second side surface 24, and an end face 25. The bottom surface 21 has a first side surface, a second side surface, a third side surface, and a fourth side surface that are continuously connected. The inclined surface 22 is connected to the first side surface of the bottom surface 21, and the inclined surface 22 and the bottom surface 21 have a certain angle. The second side surface of the bottom surface 21 extends upward to form the first side surface 23, and the first side surface 23 is connected to the inclined surface 22. The third side surface of the bottom surface 21 extends upward to form the second side surface 24, and the second side surface 24 is connected to the inclined surface 22. The fourth side surface of the bottom surface 21 extends upward to form the end face 25, and the end face 25 is connected to the inclined surface 22.

[0046] Since the inclined surface 22 and the bottom surface 21 have a certain angle, when the front frame body 11 is scraped by the tool 20, the front frame body 11 is parallel to the bottom surface 21 and the decorative piece 12 is parallel to the inclined surface 22, which can stably separate one end of the decorative piece 12 from the front frame body 11.

[0047] Please see Figure 7 and Figure 8 , Figure 7 for Figure 4 Sectional view along section line BB. Figure 8 for Figure 7A partial enlarged view at point C. In some embodiments, the thickness of the decorative piece 12 is 0.3 to 1 mm. It is understood that since the decorative piece 12 in this embodiment is formed by folding the surface of the front frame body 11 with a tool 20, the thickness of the decorative piece 12 can be compressed. This allows the decorative piece 12 to be formed while reducing its protrusion from the display screen, thus minimizing its visual presence and creating a borderless effect. For example, the thickness of the decorative piece 12 is 0.4 mm.

[0048] In some embodiments, after the surface of the front frame body 11 is scraped and bent using the tool 20, the method for manufacturing the front frame 10 of the display device further includes adjusting the angle of the decorative piece 12 relative to the front frame body 11 to provide different sized receiving spaces 13 and to accommodate different screen assemblies 30. It is understood that the decorative piece 12 is at a 90-degree angle relative to the front frame body 11. When the front frame body 11 and the decorative piece 12 are L-shaped, the receiving space 13 formed by the front frame body 11 and the decorative piece 12 is larger, and this receiving space 13 can accommodate the screen assembly 30.

[0049] This application embodiment also provides a display device front frame 10, which includes a front frame body 11 and a decorative piece 12 on the front frame body 11. The decorative piece 12 is formed by folding the surface of the front frame body 11 with a cutting tool 20. The front frame body 11 and the decorative piece 12 enclose a receiving space 13 for receiving a screen assembly 30.

[0050] The front frame body 11 and the decorative piece 12 enclose a receiving space 13, which is used to accommodate the screen assembly 30. The front frame body 11 is made of materials such as aluminum alloy and magnesium alloy, and is manufactured by injection molding or extrusion molding. The front frame body 11 is used to fix to the back panel of the display device 1.

[0051] The cutting tool 20 can fold from the middle of the front frame body 11 towards the edge, thereby folding out a thin sheet to form a decorative piece 12. The length L2 of the front frame body 11 is greater than the length L1 of the decorative piece 12. The decorative piece 12 is a rectangular structure with decorative color. When the front frame 10 of the display device is installed in the display device 1, the decorative piece 12 is located in the non-display area of ​​the front display screen of the display device 1.

[0052] The decorative piece 12 forms a preset angle with the front frame body 11, thereby enclosing and forming a receiving space 13, which is used to accommodate the screen assembly 30. The screen assembly 30 can be a screen body, a backlight module, etc.

[0053] The angle between the front frame body 11 and the decorative piece 12 is 90 degrees. When the front frame body 11 and the decorative piece 12 are L-shaped, the front frame body 11 and the decorative piece 12 form a large accommodating space 13, which can accommodate the screen assembly 30.

[0054] The decorative piece 12 has a black side facing away from the receiving space 13. When the display device 1 is in a screen-off state, the color of the decorative piece 12 is close to the color of the display screen, thus achieving a borderless display effect. The black ink coating on the side of the decorative piece 12 facing away from the receiving space 13 can be achieved by spraying or printing, such as screen printing.

[0055] The decorative piece 12 has a thickness of 0.3 to 1 mm. It is understood that since the decorative piece 12 in this embodiment is formed by scraping the surface of the front frame body 11 with a tool 20, the thickness of the decorative piece 12 can be compressed. This not only forms the decorative piece 12, but also reduces the height of the decorative piece 12 protruding from the display screen, thereby reducing the presence of the decorative piece 12 and presenting a borderless effect.

[0056] Please refer to section 4. This application embodiment also provides a display device 1, which includes a screen assembly 30 and a front frame 10. The front frame 10 is prepared by the aforementioned method for preparing the front frame 10 or is the aforementioned front frame 10. The display device 1 can be an electronic device with display function, such as a television, computer, tablet, mobile phone, or smartwatch.

[0057] The present application provides a method for manufacturing a display device front frame 10, the display device front frame 10, and a display device 1. In this method, the decorative piece 12 is formed simply by using a cutting tool 20 to fold and bend the surface of the front frame body 11. The front frame body 11 and the decorative piece 12 enclose a receiving space 13, which in turn accommodates the screen assembly 30. Therefore, this method for manufacturing the display device front frame 10 can efficiently and cost-effectively manufacture the display device front frame 10.
