[0034] 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 protection scope of this application.

[0035] An embodiment of this application provides a display module, including a display area and a frame area disposed around the display area. The display module includes a display panel, a first polarizer and a front frame. The first polarizer is disposed on the display panel and includes a main body portion corresponding to the display area and an edge portion corresponding to the frame area. The front frame covers the edge of the light-emitting surface of the display panel. The display module also includes a first light-shielding coating and a second light-shielding coating. The first light-shielding coating is disposed on the edge portion and the second light-shielding coating is disposed on the front frame.

[0036] In the embodiments of this application, by providing a first light-shielding coating on the edge of the first polarizer and a second light-shielding coating on the front frame, the color difference between the part of the corresponding border area of ​​the display module and the front frame can be reduced, thereby improving the integrated appearance of the display module.

[0037] Combination Figure 1 As shown, Figure 1 This is a perspective view of a display panel provided in an embodiment of this application. The display module has a display area AA and a border area NA, with the border area NA located around the display area AA. The display area AA is used to display the image, and may include pixel driving circuitry. The border area NA is used to house peripheral circuitry and wiring, which may include gate driving circuitry, etc.

[0038] Combination Figure 2 and Figure 3 As shown, Figure 2 The first type of display module provided for embodiments of this application is along Figure 1 The cross-sectional view along the A-A' direction shown. Figure 3 for Figure 2 The enlarged schematic diagram at point a shows that the display module 100 includes a display panel 1, a first polarizer 2, and a front frame 3. The first polarizer 2 is disposed on the display panel 1 and includes a main body portion 21 corresponding to the display area AA and an edge portion 22 corresponding to the border area NA. The front frame 3 covers the edge of the light-emitting surface of the display panel 1.

[0039] Combination Figures 1 to 3 As shown, the display module 100 also includes a first light-shielding coating 4 and a second light-shielding coating 5. The first light-shielding coating 4 is disposed on the edge portion 22, and the second light-shielding coating 5 is disposed on the front frame 3. By disposing the first light-shielding coating 4 on the edge portion 22 of the first polarizer 2 and the second light-shielding coating 5 on the front frame 3, the color difference between the corresponding border area of ​​the display module and the front frame can be reduced, thereby improving the integrated appearance of the display module.

[0040] In some embodiments, such as Figure 3 As shown, the display panel 1 is a liquid crystal display panel. The display panel 1 includes an array substrate 11, a counter substrate 12 disposed opposite to the array substrate 11, and a liquid crystal layer (not shown in the figure) located between the array substrate 11 and the counter substrate 12. A first polarizer 2 is disposed on the surface of the counter substrate 12 away from the array substrate 11. The first polarizer 2 can be bonded to the upper surface of the counter substrate 12 by optical adhesive.

[0041] In some embodiments, the color difference between the first light-shielding coating 4 and the second light-shielding coating 5 is less than 1. For example, the color difference between the first light-shielding coating 4 and the second light-shielding coating 5 can be 1, 0.8, 0.6, 0.4, 0.2, 0.1, or 0. This makes the color difference between the first light-shielding coating 4 and the second light-shielding coating 5 smaller, so that the colors of the first light-shielding coating 4 and the second light-shielding coating 5 are closer, thereby improving the integrated appearance of the display module.

[0042] In some embodiments, the first light-shielding coating 4 and the second light-shielding coating 5 are the same color, that is, the color difference between the first light-shielding coating 4 and the second light-shielding coating 5 is 0. This allows the edge portion 22 of the first polarizer 2 to have the same color as the front frame 3, thereby further improving the integrated appearance of the display module.

[0043] In some embodiments, the first light-shielding coating 4 and the second light-shielding coating 5 are both black.

[0044] In some embodiments, the front frame 3 includes a front panel 31 and a first side panel 32 connected to the front panel 31. One end of the front panel 31 overlaps the edge of one side of the light-emitting surface of the display panel 1. The front panel 31 is parallel to the light-emitting surface of the display panel 1. The first side panel 32 is bent along the thickness direction of the display module. The front panel 31 covers the edge of one side of the light-emitting surface of the display panel 1. The first side panel 32 covers one side of the display panel 1. A first light-shielding coating 4 is disposed on the front panel 31 and the first side panel 32. The first polarizer 2 is spaced apart from the front panel 31 in the direction from the display area AA to the frame area NA.

[0045] like Figure 3 As shown, one end of the front panel 31 overlaps the surface of the opposing substrate 12 away from the array substrate 11, and the first polarizer 2 is disposed on the surface of the opposing substrate 12 away from the array substrate 11. The front panel 31 is flush with the first polarizer 2. By making the front panel 31 flush with the first polarizer 2, the height difference between the first light-shielding coating 4 and the second light-shielding coating 5 can be reduced. This avoids color differences in visual effect caused by a large height difference between the first light-shielding coating 4 and the second light-shielding coating 5, thereby further improving the integrated appearance of the display module.

[0046] In some embodiments, such as Figure 3 As shown, in the direction from the display area AA to the bezel area NA, there is a first distance d1 between the first polarizer 2 and the front panel 31. The first distance d1 is greater than 0 and less than or equal to 0.1 mm. For example, the first distance d1 can be 0.01 mm, 0.03 mm, 0.05 mm, 0.07 mm, or 0.1 mm, etc. This avoids a noticeable gap between the first polarizer 2 and the front bezel 3, thereby further improving the integrated appearance of the display module.

[0047] In some embodiments, such as Figure 3 As shown, both the first light-shielding coating 4 and the second light-shielding coating 5 are conductive. The first light-shielding coating 4 is grounded through the second light-shielding coating 5 and the front frame 3. When an electric charge strikes, the charge in the frame area NA can be conducted to the front frame 3 through the first light-shielding coating 4 and the second light-shielding coating 5, and then grounded through the front frame 3. This improves the side electrostatic protection capability of the display module, eliminating the need to attach conductive cloth to the side of the display module. Therefore, it not only improves the integrated appearance of the display module, but also simplifies the structure of the display module, reduces the assembly difficulty of the display module, and lowers the production cost of the display module.

[0048] In some embodiments, such as Figure 3 As shown, the display module 100 also includes a backlight module 6, which is disposed on the light-incident side of the display panel 1. The backlight module 6 includes a back plate 61, the front frame 3 is electrically connected to the back plate 61, and the first light-shielding coating 4 is grounded through the second light-shielding coating 5, the front frame 3 and the back plate 61.

[0049] Both the front frame 3 and the back plate 61 are conductive. When subjected to an electrical charge, the charge in the frame area NA can be conducted to the front frame 3 through the first light-shielding coating 4 and the second light-shielding coating 5, and then connected to the back plate 61 from the front frame 3 to achieve grounding. This improves the side electrostatic protection capability of the display module, eliminating the need to attach conductive cloth to the side of the display module. Therefore, it not only improves the integrated appearance of the display module but also simplifies its structure, reduces assembly difficulty, and lowers production costs.

[0050] In some embodiments, such as Figure 3 As shown, the display module 100 includes a conductive connector 7, and the front frame 3 is electrically connected to the back panel 61 through the conductive connector 7.

[0051] like Figure 3 As shown, the conductive connector 7 is disposed between the front frame 3 and the back plate 61. The front frame 3 can be fixedly connected to the back plate 61 via the conductive connector 7, or the front frame 3 can be detachably connected to the back plate 61 via the conductive connector 7. The conductive connector 7 is conductive and can electrically connect the front frame 3 and the back plate 61, so that the charge can be grounded through the first light-shielding coating 4, the second light-shielding coating 5, the front frame 3, the magnet, and the back plate 61.

[0052] In some embodiments, such as Figure 3 As shown, the conductive connector 7 includes a magnet. The front frame 3 and the back plate 61 are both made of metal. The front frame 3 can be attracted and fixed together with the back plate 61 by the magnet. The front frame 3 can also be electrically connected to the back plate 61 by the magnet, so that the charge can be grounded through the first light-shielding coating 4, the second light-shielding coating 5, the front frame 3, the magnet and the back plate 61.

[0053] In some embodiments, such as Figure 3 As shown, the conductive connector 7 includes conductive tape. The front frame 3 and the back plate 61 can be bonded together by the conductive tape. The front frame 3 can also be electrically connected to the back plate 61 by the conductive tape, so that the charge can be grounded through the first light-shielding coating 4, the second light-shielding coating 5, the front frame 3, the magnet and the back plate 61.

[0054] In some embodiments, such as Figure 3 As shown, the backlight module 6 also includes a light source assembly 62. The back plate 61 includes a bottom plate 611 and a second side plate 612. The second side plate 612 is erected on the periphery of the bottom plate 611. The bottom plate 611 and the second side plate 612 enclose a receiving cavity, in which the light source assembly 62 is housed.

[0055] In some embodiments, such as Figure 3 As shown, the end of the second side plate 612 away from the bottom plate 611 is bent, and the conductive connector 7 is disposed between one end of the side plate 612 and the front frame 3 to connect the front frame 3 and the side plate 612 and make them electrically connected.

[0056] In some embodiments, such as Figure 3 As shown, the light source assembly 62 includes a light source 621, a light guide plate 622, and a reflector 623. The light source 621 is disposed at one end of the light guide plate 622. The light source 621 can be fixedly installed on the light guide plate 622 or the back plate 61. The light source 621 includes a circuit board and a light-emitting element. The reflector 623 is disposed at the bottom of the light guide plate 622.

[0057] In some embodiments, such as Figure 3 As shown, the backlight module 6 also includes an optical film 63, which is disposed on the side of the light guide plate 622 near the display panel 1. The optical film 63 may include at least one of a brightness enhancement film, a diffusion film, and a prism film.

[0058] In some embodiments, such as Figure 3 As shown, the backlight module 6 also includes a frame 64, which is mounted on the back plate 61. The display module 100 also includes a first adhesive member 8, which is disposed between the display panel 1 and the frame 64, and the display panel 1 is fixedly connected to the frame 64 through the first adhesive member 8.

[0059] In some embodiments, such as Figure 3 As shown, the display module 100 also includes a lower polarizer 9, which is disposed on the side of the display panel 1 near the backlight module 6.

[0060] In some embodiments, combined with Figures 1 to 4 As shown, Figure 4 for Figure 2The enlarged schematic diagram at point b shows that the front frame 3 is located on one side of the display panel 1 and covers one edge of the display panel 1. The other side edges of the display panel 1 do not cover the front frame 3. On the other side edges of the display panel 1, the edge portion 22 of the first polarizer 2 is provided with a first light-shielding coating 4. This can ensure the color consistency of the four edges of the display module, thereby further improving the integrated appearance of the display module.

[0061] Combination Figure 5 and Figure 6 As shown, Figure 5 The second display module provided for embodiments of this application is along Figure 1 The cross-sectional view along the A-A' direction shown. Figure 6 for Figure 5 An enlarged schematic diagram at point c in the diagram shows its structure is similar to... Figures 2 to 4 The structure of the first type of display module shown is roughly the same, except that one end of the front panel 31 overlaps the edge portion 22.

[0062] like Figure 6 As shown, the first light-shielding coating 4 is disposed on the edge portion 22 of the first polarizer 2, and a portion of the front panel 31 of the front frame 3 overlaps the edge portion 22 and covers part of the first light-shielding coating 4. The second light-shielding coating 5 is disposed on the front panel 31, and the second light-shielding coating 5 and the first light-shielding coating 4 partially overlap in the thickness direction of the display module. This can eliminate the gap between the first light-shielding coating 4 and the second light-shielding coating 5 in the horizontal direction, thereby further improving the integrated appearance of the display module.

[0063] In some embodiments, the thickness of the front frame 3 is greater than or equal to 0.15 mm and less than or equal to 0.3 mm. For example, the thickness of the front frame 3 can be 0.15 mm, 0.18 mm, 0.2 mm, 0.23 mm, 0.25 mm, 0.28 mm, or 0.3 mm, etc. Because the front frame 3 is thin, even if the front frame 3 is attached to the edge portion 22 of the first polarizer 2, it can be ensured that the front appearance of the display module is still close to a single piece.

Please refer to [link to relevant documentation]. Figure 7 , Figure 7 This is a schematic diagram of a display device provided in an embodiment of this application.
