The display panel comprises a display area and a frame area arranged on one side of the display area. The frame area comprises a first sub-frame area and a second sub-frame area arranged on both sides of the first sub-frame area. The polarizing layer is arranged on the light-emitting side of the display panel. The protective layer is partially arranged on the first sub-frame area, and the orthographic projection of the protective layer on the display panel does not overlap with the second sub-frame area.

Description

Technical Field

[0001] This application relates to the field of electronic technology, and more particularly to a display panel and display device. Background Technology

[0002] Organic light-emitting diode (OLED) display technology has attracted widespread attention due to its advantages such as self-illumination, wide viewing angle, high contrast, low power consumption, and fast response speed. An OLED display module mainly consists of a backplane, a display panel, and a cover glass. Since the cover glass is easily affected by ambient light, a polarizing layer needs to be placed between the display panel and the cover glass to eliminate ambient light and make the color and brightness of the light emitted by the OLED display panel more uniform.

[0003] Static electricity on the cover plate surface will move along the edge of the cover plate to the side of the display panel. Since there is UV curing adhesive on both sides of the bottom bezel of the display panel, the UV curing adhesive will block the path of static electricity to the interface between the polarizer and the display panel, causing more static electricity to enter the interface between the display panel and the back plate. This results in an increase in the amount of static electricity accumulated on both sides of the bottom bezel of the display panel, causing abnormal brightness on both sides of the bottom bezel of the display panel.

[0004] Therefore, it is necessary to provide a display module and display device to improve this deficiency. Summary of the Invention

[0005] This application provides a display module and display device that can solve the problem of abnormal brightness on both sides of the lower bezel of the display panel.

[0019] Optionally, one end of the adhesive layer near the frame area protrudes beyond the end of the first polarizing portion near the frame area, and the protective layer is partially disposed between the end of the adhesive layer near the frame area and the end of the first sub-frame area near the bending area.

[0020] Optionally, the material of the protective layer includes a UV-curable adhesive.

[0021] According to a second aspect of this application, a display device is provided, comprising a liquid crystal display module as described in any of the above embodiments.

[0022] In the display module of this application embodiment, by setting the protective layer part on the first sub-bezel area of ​​the bezel area and making the orthographic projection of the protective layer on the display panel not overlap with the second sub-bezel area, the protective layer is prevented from blocking the path of static electricity into the interface between the polarizing layer and the display panel, and a large amount of static electricity is prevented from accumulating in the second sub-bezel area, thereby improving the abnormal brightness on both sides of the bezel area of ​​the display panel.

[0037] 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.

[0038] This application provides a display module, which includes a display panel, a polarizing layer, and a protective layer. The display panel includes a display area, a frame area disposed on one side of the display area, a bending area disposed on the side of the frame area away from the display area, and a terminal area disposed on the side of the bending area away from the frame area. The frame area includes a first sub-frame area and second sub-frame areas disposed on both sides of the first sub-frame area. The polarizing layer is disposed on the light-emitting side of the display panel, and the protective layer is partially disposed on the first sub-frame area. The orthographic projection of the protective layer on the display panel does not overlap with the second sub-frame area.

[0039] In this embodiment, by setting a portion of the protective layer on the first sub-bezel area of ​​the bezel area and ensuring that the orthographic projection of the protective layer on the display panel does not overlap with the second sub-bezel area, the protective layer is prevented from blocking the path of static electricity into the interface between the polarizing layer and the display panel, thus preventing the accumulation of a large amount of static electricity in the second sub-bezel area. This can improve the abnormal brightness on both sides of the bezel area of ​​the display panel.

[0040] Combination Figure 1 As shown, Figure 1 The top view of the display module provided in the embodiment of this application shows that the display module 100 includes a display panel 1. The display panel 1 includes a display area 11, a frame area 12 disposed on one side of the display area 11, a bending area 16 disposed on the side of the frame area 12 away from the display area 11, and a terminal area 17 disposed on the side of the bending area 16 away from the frame area 12. The frame area 12 includes a first sub-frame area 121 and a second sub-frame area 122 disposed on both sides of the first sub-frame area 121. The first sub-frame area 121 is adjacent to the bending area 16.

[0041] In the embodiments of this application, the border area 12 can be regarded as the lower border area of ​​the display panel 1, the first sub-border area 121 is the area in the lower border area that intersects with the bending area 16, and the two second sub-border areas 122 can be symmetrically arranged about the first sub-border area 121. The display panel 1 may also include a left border area 13 and a right border area 14 disposed on the left and right sides of the display area 11, and an upper border area 15 disposed on the upper side of the display area 11.

[0042] Combination Figures 1 to 3 As shown, Figure 2 The display module provided for the embodiments of this application is along Figure 1 The cross-sectional view along the A-A' direction shown. Figure 3 The display module provided for the embodiments of this application is along Figure 1 The cross-sectional view along the B-B' direction shown shows that the display module 100 also includes a polarizing layer 2 and a protective layer 3. The polarizing layer 2 is disposed on the light-emitting side of the display panel 1, and the protective layer 3 is partially disposed on the first sub-frame area 121. The other part of the protective layer 3 extends from the first sub-frame area 121 to the bending area 16 and the terminal area 17. The polarizing layer 2 is a polarizer or a polarizing film.

[0043] In the embodiments of this application, the display panel 1 can be an organic light-emitting diode display panel or a micro light-emitting diode display panel.

[0044] Combination Figure 3 and Figure 4 As shown, Figure 4 The schematic diagram shows the structure of the display module in a bent state according to an embodiment of this application. It should be noted that... Figure 4 The diagram shows the final product form of the display module. The terminal area 17 can be bent along with the bending area 16 to the side of the display area 11 away from the polarizing layer 2, and the bending area 16 is bent. The protective layer 3 is partially disposed on the outer surface of the bending area 16 and the terminal area 17. The protective layer 3 can not only keep the bending area 16 bent and prevent the bending area 16 from deforming or collapsing, but also absorb the impact force applied by the outside, reducing the risk of damage to the bending area 16 caused by external impact.

[0045] In some embodiments, the material of the protective layer 3 includes a UV-curable adhesive.

[0046] Combination Figures 1 to 4 As shown, the protective layer 3 is partially disposed on the first sub-bezel area 121. The orthographic projection of the protective layer 3 on the display panel 1 does not overlap with the second sub-bezel area 122, that is, the second sub-bezel area 122 is not provided with the protective layer 3. This can prevent the protective layer 3 from blocking the path of static electricity at the second sub-bezel area 122 into the interface between the polarizing layer 2 and the display panel 1, and prevent a large amount of static electricity from accumulating at the second sub-bezel area 122, thereby improving the abnormal brightness on both sides of the bezel area of ​​the display panel.

[0047] In some embodiments, combined with Figure 1 and Figure 5 As shown, Figure 5 The polarizing layer 2 provided in the embodiment of this application is a top view. The polarizing layer 2 includes a first polarizing part 21 and a second polarizing part 22 disposed on both sides of the first polarizing part 21. The first polarizing part 21 is partially disposed on the first sub-bezel area 121, and the second polarizing part 22 is partially disposed on the second sub-bezel area 122. The end of the second polarizing part 22 near the bezel area 12 is flush with the end of the second sub-bezel area 122 away from the display area 11.

[0048] Combination Figure 1 , Figure 2 and Figure 5 As shown, the polarizing layer 2 is divided into three parts: a first polarizing part 21 located in the middle, and two second polarizing parts 22 respectively disposed on the left and right sides of the first polarizing part 21. The first polarizing part 21 and the two second polarizing parts 22 are an integral structure, belonging to different parts of the same polarizer. The first polarizing part 21 is partially disposed on the first sub-bezel area 121, and the second polarizing part 22 is disposed on the second sub-bezel area 122 near the bezel area 12. The end of the second polarizing part 22 near the bezel area 12 is flush with the end of the second sub-bezel area 122 away from the display area 11. This allows the edge of the polarizing layer 2 at the second sub-bezel area 122 to be flush with the edge of the second sub-bezel area 122, so that there is no gap between the edge of the polarizing layer 2 at the second sub-bezel area 122 and the edge of the second sub-bezel area 122 to accommodate the protective layer 3. This prevents the protective layer 3 from blocking the path of static electricity at the second sub-bezel area 122 to enter the interface between the polarizing layer 2 and the display panel 1, and prevents the accumulation of a large amount of static electricity at the second sub-bezel area 122, thereby improving the abnormal brightness on both sides of the bezel area of ​​the display panel.

[0049] In some embodiments, combined with Figure 2 and Figure 4 As shown, the end of the first sub-bezel area 121 away from the display area 11 protrudes from the end of the first polarizing part 21 near the bezel area 12. This allows for a certain space to be reserved on the end of the first sub-bezel area 121 away from the display area 11 for placing the protective layer 3. The protective layer 3 protects the end of the first sub-bezel area 121 near the bending area 16, reducing the risk of damage to the part of the first sub-bezel area 121 near the bending area 16 when subjected to external impact.

[0050] In some embodiments, such as Figure 2As shown, the display module 100 includes a first back plate 4, which is disposed on the side of the display panel 1 away from the polarizing layer 2. The portions of the display panel 1 corresponding to the display area 11 and the bezel area 12 are all disposed on the first back plate 4. The end of the second polarizing part 22 near the bezel area 12 is flush with the end of the first back plate 4 near the bezel area 12. By making the end of the second polarizing part 22 near the bezel area 12 flush with the end of the first back plate 4 near the bezel area 12 and the end of the second sub-bezel area 122 away from the display area 11, there is no space at the edges of the lower bezel of the display panel for accommodating the protective layer 3. This prevents the UV-curing adhesive applied during the formation of the protective layer 3 from overflowing from the first sub-bezel area 121 to the second sub-bezel area 122, thereby avoiding the accumulation of a large amount of static electricity in the second sub-bezel area 122 due to the formation of the protective layer 3. This improves the abnormal brightness on both sides of the bezel area of ​​the display panel.

[0051] In some embodiments, the end of the first backplate 4 near the frame area 12 protrudes from the end of the first polarizing portion 21 near the frame area 12.

[0052] Combination Figure 3 and Figure 4 As shown, the end of the first sub-bezel area 121 furthest from the display area 11 protrudes from the end of the first backplate 4 near the bezel area 12. The portion of the first polarizing part 21 near the bezel area 12 is disposed on the first sub-bezel area 121, and the end of the first backplate 4 near the bezel area 12 protrudes from the end of the first polarizing part 21 near the bezel area 12. A protective layer 3 is partially disposed on the portion of the first sub-bezel area 121 near the bending area 16. The protective layer 3 is disposed on the same layer as the polarizing layer 2, and the end of the protective layer 3 near the display area 11 is adjacent to the end of the first polarizing part 21 near the bezel area 12. By making the end of the first backplate 4 near the bezel area 12 protrude from the end of the first polarizing part 21 near the bezel area 12, a certain space is reserved on the first sub-bezel area 121 above the first backplate 4 to accommodate the protective layer 3. This allows the protective layer 3 to protect the edge of the first sub-bezel area 121 near the first backplate 4, reducing the risk of damage to this portion when subjected to external impact.

[0053] In some embodiments, the end of the second polarizing portion 22 near the frame region 12 protrudes from the end of the first polarizing portion 21 near the frame region 12.

[0054] Combination Figures 2 to 5As shown, the outline of the polarizing layer 2 is adapted to the outline of the display panel 1. The part of the polarizing layer 2 corresponding to the bezel area 12 adopts an irregular design, that is, the end of the second polarizing part 22 near the bezel area 12 protrudes from the end of the first polarizing part 21 near the bezel area 12. This not only makes the end of the second polarizing part 22 near the bezel area 12 flush with the end of the first back plate 4 near the bezel area 12 and the end of the second sub-bezel area 122 away from the display area 11, but also prevents the UV curing adhesive applied when forming the protective layer 3 from overflowing from the first sub-bezel area 121 to the second sub-bezel area 122. This avoids the accumulation of a large amount of static electricity in the second sub-bezel area 122 due to the formation of the protective layer 3, thereby improving the abnormal brightness on both sides of the bezel area of ​​the display panel. The protective layer 3 can also protect the edge of the first sub-bezel area 121 near the first back plate 4, reducing the risk of damage to the edge of the first sub-bezel area 121 near the first back plate 4 when subjected to external impact.

[0055] In some embodiments, combined with Figure 3 and Figure 4 As shown, the display module 100 includes a composite support heat dissipation layer 7 and a second back plate 8. The portion of the display panel 1 corresponding to the display area 11 and the frame area 12 is disposed on the first back plate 4, and the portion of the display panel corresponding to the terminal area 17 is disposed on the second back plate 8. The portion of the display panel corresponding to the terminal area 17 and the second back plate 8 are bent along the bending area 16 to the side of the first back plate 4 away from the portion of the display panel 1 corresponding to the display area 11. The composite support heat dissipation layer 7 is disposed between the first back plate 4 and the second back plate 8.

[0056] In some embodiments, the composite support heat dissipation layer 7 may include a buffer layer, a heat dissipation layer and a support layer (not shown in the figure) stacked together, wherein the buffer layer is made of foam and the heat dissipation layer is made of metal.

[0057] In some embodiments, combined with Figure 3 and Figure 4 As shown, the display module 100 also includes an adhesive layer 5 and a cover plate 6. The adhesive layer 5 is disposed on the side of the polarizing layer 2 away from the display panel 1, and the cover plate 6 is disposed on the side of the adhesive layer 5 away from the polarizing layer 2. One end of the adhesive layer 5 near the frame area 12 protrudes from the end of the first polarizing part 21 near the frame area 12. A protective layer 3 is partially disposed between the end of the adhesive layer 5 near the frame area 12 and the end of the first sub-frame area 121 near the bending area 16. In this way, the protective layer 3 protects the part of the first sub-frame area 121 near the bending area 16, reducing the risk of damage to the part of the first sub-frame area 121 near the bending area 16 when subjected to external impact.

[0058] In some embodiments, the cover plate 6 is a glass cover plate, and the adhesive layer 5 is a transparent optical adhesive.

[0059] In some embodiments, such as Figure 3 As shown, the end of the second polarizing part 22 near the frame area 12 protrudes from the end of the adhesive layer 5 near the frame area 12. This prevents the UV-curing adhesive applied during the formation of the protective layer 3 from overflowing from the first sub-frame area 121 to the gap between the adhesive layer 5 and the second sub-frame area 122. This avoids the accumulation of a large amount of static electricity in the second sub-frame area 122 due to the formation of the protective layer 3, thereby improving the abnormal brightness on both sides of the frame area of ​​the display panel.

[0060] In some embodiments, the end of the second polarizing portion 22 near the frame area 12 is flush with the end of the adhesive layer 5 near the frame area 12. This also prevents the UV-curing adhesive applied when forming the protective layer 3 from overflowing from the first sub-frame area 121 to the gap between the adhesive layer 5 and the second sub-frame area 122, thereby avoiding the accumulation of a large amount of static electricity in the second sub-frame area 122 due to the formation of the protective layer 3, which can improve the abnormal brightness on both sides of the frame area of ​​the display panel.

Figure 6 As shown, Figure 6 This is a schematic diagram of the structure of a display device provided in an embodiment of this application.

The display panel includes a display area, a frame area disposed on one side of the display area, a bending area disposed on the side of the frame area away from the display area, and a terminal area disposed on the side of the bending area away from the frame area. The frame area includes a first sub-frame area and second sub-frame areas disposed on both sides of the first sub-frame area. The polarizing layer is disposed on the light-emitting side of the display panel. By partially disposing the protective layer on the first sub-frame area and ensuring that the orthographic projection of the protective layer on the display panel does not overlap with the second sub-frame area, the protective layer is prevented from blocking the path of static electricity into the interface between the polarizing layer and the display panel, and a large amount of static electricity is prevented from accumulating in the second sub-frame area. This can improve the abnormal brightness on both sides of the frame area of ​​the display panel.
