Description

Technical Field

[0001] The present application relates to the field of electronic technology, and in particular to a display panel and a display device. Background Art

[0002] Organic Light-Emitting Diode (OLED) display technology has the advantages of self-luminescence, wide viewing angle, high contrast, low power consumption, and fast response speed, and has attracted widespread attention. The OLED display module mainly includes a backplane, a display panel, and a cover plate. Since the cover plate is easily affected by ambient light, a polarizing layer needs to be set between the display panel and the cover plate to eliminate ambient light, so as to make the color and brightness of the light emitted by the OLED display panel more uniform.

[0003] Static electricity on the surface of the cover plate will move along the edge of the cover plate to the side of the display panel. Since there is UV light-curing adhesive on both sides of the lower frame of the display panel, the UV light-curing adhesive will block the path of static electricity moving to the interface between the polarizer and the display panel, allowing more static electricity to enter the interface between the display panel and the back panel, resulting in an increase in the amount of static electricity accumulated on both sides of the lower frame of the display panel, causing both sides of the lower frame of the display panel to become abnormally bright.

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

[0005] The embodiments of the present application provide a display module and a display device, which can solve the problem of abnormal brightness of parts on both sides of the lower frame of the display panel.

[0009] Optionally, one end of the first sub-frame area away from the display area protrudes beyond one end of the first polarizing portion close to the frame area.

[0010] Optionally, the display module includes a first back plate, which is arranged on a side of the display panel away from the polarizing layer, and an end of the second polarizing portion close to the frame area is arranged flush with an end of the first back plate close to the frame area.

[0011] Optionally, one end of the first back plate close to the frame area protrudes beyond one end of the first polarizing portion close to the frame area.

[0012] Optionally, the display module further includes: An adhesive layer, disposed on a side of the polarizing layer away from the display panel; A cover plate, disposed on a side of the adhesive layer away from the polarizing layer; Wherein, one end of the second polarizing portion close to the frame area is flush with one end of the adhesive layer close to the frame area; or, one end of the second polarizing portion close to the frame area protrudes from one end of the adhesive layer close to the frame area.

[0015] According to a second aspect of the present application, a display device is provided, comprising a liquid crystal display module as described in any one of the above embodiments.

[0016] In the display module of the embodiment of the present application, the protective layer is partially disposed on the first sub-frame area of ​​the frame area, and the orthographic projection of the protective layer on the display panel does not overlap with the second sub-frame area.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0022] The present 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 arranged on one side of the display area, a bending area arranged on a side of the frame area away from the display area, and a terminal area arranged on a side of the bending area away from the frame area. The frame area includes a first sub-frame area and second sub-frame areas arranged on both sides of the first sub-frame area. The polarizing layer is arranged on the light emitting side of the display panel, and the protective layer is partially arranged on the first sub-frame area.

[0023] In this embodiment, a portion of the protective layer is disposed on the first sub-frame area of ​​the frame area, and the orthographic projection of the protective layer on the display panel does not overlap with the second sub-frame area. This prevents the protective layer from blocking the path of static electricity entering the interface between the polarizing layer and the display panel, thereby preventing a large amount of static electricity 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.

[0024] Combination Figure 1 As shown, Figure 1 The top view of the display module provided in the embodiment of the present application, the display module 100 includes a display panel 1, the display panel 1 includes a display area 11, a frame area 12 arranged on one side of the display area 11, a bending area 16 arranged on a side of the frame area 12 away from the display area 11, and a terminal area 17 arranged on a side of the bending area 16 away from the frame area 12, the frame area 12 includes a first sub-frame area 121 and second sub-frame areas 122 arranged on both sides of the first sub-frame area 121, and the first sub-frame area 121 is adjacent to the bending area 16.

[0025] In the embodiment of the present application, the frame area 12 can be regarded as the lower frame area of ​​the display panel 1, the first sub-frame area 121 is the area in the lower frame area that intersects with the bending area 16, and the two second sub-frame areas 122 can be symmetrically arranged about the first sub-frame area 121. The display panel 1 may also include a left frame area 13 and a right frame area 14 arranged on the left and right sides of the display area 11, and an upper frame area 15 arranged on the upper side of the display area 11.

[0026] Combination Figures 1 to 3As shown, Figure 2 The display module provided in the embodiment of the present application is Figure 1 The cross-sectional view along the A-A' direction is shown. Figure 3 The display module provided in the embodiment of the present application is Figure 1 As shown in the cross-sectional view in the BB' direction, the display module 100 also includes a polarizing layer 2 and a protective layer 3. The polarizing layer 2 is arranged on the light-emitting side of the display panel 1, and a portion of the protective layer 3 is arranged on the first sub-frame area 121. The other portion 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 polarizing plate or a polarizing film.

[0027] In the embodiment of the present application, the display panel 1 may be an organic light emitting diode display panel or a micro light emitting diode display panel.

[0028] Combination Figure 3 and Figure 4 As shown, Figure 4 The structural diagram of the bending state of the display module provided in the embodiment of the present application needs to be explained as follows: Figure 4 The final product form of the display module is shown. 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 curved. 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 be used to maintain the bending area 16 in a curved state and prevent the bending area 16 from deformation or collapse, but also absorb the impact force applied by the outside, reducing the risk of damage to the bending area 16 caused by external impact.

[0029] In some embodiments, the material of the protection layer 3 includes ultraviolet light curing glue.

[0030] Combination Figures 1 to 4 As shown, the protective layer 3 is partially arranged on the first sub-frame area 121, and the orthographic projection of the protective layer 3 on the display panel 1 does not overlap with the second sub-frame area 122, that is, the protective layer 3 is not arranged on the second sub-frame area 122. In this way, the protective layer 3 can be prevented from blocking the path of static electricity in the second sub-frame area 122 entering the interface between the polarizing layer 2 and the display panel 1, thereby preventing a large amount of static electricity from accumulating in the second sub-frame area 122, thereby improving the abnormal brightness on both sides of the frame area of ​​the display panel.

The first polarizing part 21 and the two second polarizing parts 22 are an integrated structure, and the first polarizing part 21 and the two second polarizing parts 22 belong to different parts of the same polarizer.

[0033] In some embodiments, in combination Figure 2 and Figure 4 As shown, one end of the first sub-frame area 121 away from the display area 11 protrudes from the end of the first polarizing portion 21 close to the frame area 12, so that a certain space can be reserved on the end of the first sub-frame area 121 away from the display area 11 for placing the protective layer 3, and the protective layer 3 is used to protect the end of the first sub-frame area 121 close to the bending area 16, thereby reducing the risk of damage to the portion of the first sub-frame area 121 close to the bending area 16 due to external force impact.

By making the end of the second polarizing portion 22 close to the frame area 12 and the end of the first backplane 4 close to the frame area 12 and the end of the second sub-frame area 122 away from the display area 11 be arranged flush, it is possible to make the second polarizing portion 22 and the first backplane 4 and the second sub-frame area 122 have no space at the edges of both sides of the lower frame of the display panel for accommodating the protective layer 3, so as to prevent the ultraviolet curing glue applied when forming the protective layer 3 from overflowing from the first sub-frame area 121 to the second sub-frame area 122, so as to avoid the formation of the protective layer 3 in the second sub-frame area 122 and causing a large amount of static electricity to accumulate there, thereby improving the abnormal brightness of both sides of the frame area of ​​the display panel.

[0035] In some embodiments, one end of the first back plate 4 close to the frame area 12 protrudes from one end of the first polarizing portion 21 close to the frame area 12 .

[0036] Combination Figure 3 and Figure 4 As shown, one end of the first sub-frame area 121 away from the display area 11 protrudes from one end of the first back plate 4 close to the frame area 12.

The protective layer 3 is arranged on the same layer as the polarizing layer 2, and one end of the protective layer 3 close to the display area 11 is adjacent to one end of the first polarizing unit 21 close to the frame area 12. By making one end of the first back plate 4 close to the frame area 12 protrude from one end of the first polarizing unit 21 close to the frame area 12, a certain space is reserved on the first sub-frame area 121 above the first back plate 4 for accommodating the protective layer 3, so that the protective layer 3 is used to protect the portion of the first sub-frame area 121 close to the edge of the first back plate 4, thereby reducing the risk of damage to the portion of the first sub-frame area 121 close to the edge of the first back plate 4 when it is impacted by external force.

[0037] In some embodiments, one end of the second polarizer 22 close to the frame area 12 protrudes beyond one end of the first polarizer 21 close to the frame area 12 .

[0038] Combination Figures 2 to 5As shown, the outer contour of the polarizing layer 2 is adapted to the outer contour of the display panel 1, and the portion of the polarizing layer 2 corresponding to the frame area 12 adopts a special-shaped design, that is, the end of the second polarizing portion 22 close to the frame area 12 protrudes from the end of the first polarizing portion 21 close to the frame area 12, so that not only the end of the second polarizing portion 22 close to the frame area 12 can be flush with the end of the first back plate 4 close to the frame area 12 and the end of the second sub-frame area 122 away from the display area 11, so as to prevent the UV curing glue applied when forming the protective layer 3 from overflowing from the first sub-frame area 121 to the second sub-frame area 122, so as to avoid the formation of the protective layer 3 in the second sub-frame area 122 causing a large amount of static electricity to accumulate there, thereby improving the abnormal brightness of both sides of the frame area of ​​the display panel, and the protective layer 3 can also be used to protect the portion of the first sub-frame area 121 close to the edge of the first back plate 4, thereby reducing the risk of damage to the portion of the first sub-frame area 121 close to the edge of the first back plate 4 due to external force impact.

[0041] In some embodiments, in combination Figure 3 and Figure 4 As shown, the display module 100 further includes an adhesive layer 5 and a cover plate 6, wherein the adhesive layer 5 is disposed on a side of the polarizing layer 2 away from the display panel 1, and the cover plate 6 is disposed on a side of the adhesive layer 5 away from the polarizing layer 2. One end of the adhesive layer 5 close to the frame area 12 protrudes from one end of the first polarizing portion 21 close to the frame area 12, and the protective layer 3 is partially disposed between one end of the adhesive layer 5 close to the frame area 12 and one end of the first sub-frame area 121 close to the bending area 16, so that the protective layer 3 is used to protect the part of the first sub-frame area 121 close to the bending area 16, thereby reducing the risk of damage to the part of the first sub-frame area 121 close to the bending area 16 due to external force impact.

[0042] In some embodiments, the cover plate 6 is a glass cover plate, and the adhesive layer 5 is a transparent optical adhesive.

[0043] In some embodiments, Figure 3 As shown, one end of the second polarizing portion 22 near the frame area 12 protrudes from the other end of the adhesive layer 5 near the frame area 12, so as to prevent 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 formation of the protective layer 3 in the second sub-frame area 122 and causing a large amount of static electricity to accumulate there, thereby improving the abnormal brightness on both sides of the frame area of ​​the display panel.

[0044] In some embodiments, one end of the second polarizing portion 22 close to the border area 12 is arranged flush with the end of the adhesive layer 5 close to the border area 12. This can also prevent the UV-curable adhesive applied when forming the protective layer 3 from overflowing from the first sub-border area 121 to the gap between the adhesive layer 5 and the second sub-border area 122, thereby avoiding the formation of the protective layer 3 in the second sub-border area 122, which causes a large amount of static electricity to accumulate there, thereby improving the abnormal brightness on both sides of the border area of ​​the display panel.
