Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there can be a central component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there can be a central component at the same time.

[0033] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this application and in the specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in this application includes any and all combinations of one or more of the related listed items.

[0034] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0035] Please refer to Figure 1 and Figure 2 The embodiment of the present application provides a display module, including a display panel 10, an adhesive member 20, a bottom frame 30, an edge member 40 and a fixing adhesive 50. The components of the display module of the embodiment of the present application can be roughly symmetrical in structure, and only one side of the symmetrical part is described below, and the other side can be used for reference without detailed description.

[0036] The display panel 10 includes a first substrate 12 and a second substrate 13 that are arranged opposite to each other. The side of the second substrate 13 facing away from the first substrate 12 is a light emitting surface. The edges of the second substrate 13 are retracted relative to the first substrate 12 .

[0037] The edges of the second substrate 13 are retracted relative to the first substrate 12, that is, the orthographic projection of the second substrate 13 on the first substrate 12 is entirely located within the first substrate 12, and each edge of the second substrate 13 is spaced apart from each corresponding edge of the second substrate 13, and the area of ​​the surface of the second substrate 13 facing the first substrate 12 is smaller than the area of ​​the surface of the first substrate 12 facing the second substrate 13. The width of the retracted second substrate 13 relative to the first substrate 12 may be greater than or equal to 0.5 mm, so that the portion of the first substrate 12 that exceeds the second substrate 13 has enough space for connecting the edging member 40, the fixing glue 50, etc. described later.

[0038] The display panel 10 further includes various layers of structures (not shown) disposed between the first substrate 12 and the second substrate 13 . The edges of the various layers of structures disposed between the first substrate 12 and the second substrate 13 should not exceed the edges of the second substrate 13 .

[0039] The display panel 10 may specifically be a liquid crystal panel, an OLED (Organic Light-Emitting Diode) panel, a Micro-LED (Micro-Light-Emitting Diode) panel, or the like.

[0040] It is understandable that this application Figure 1 and Figure 2 The display panel 10 shown only shows a simplified display panel 10 , and does not show the entire structure of the display panel 10 .

[0041] Taking the display panel 10 as a liquid crystal panel as an example, the first substrate 12 and the second substrate 13 may be glass substrates, and the layers therebetween include a liquid crystal molecule layer, a color filter, and the like.

[0042] Taking the display panel 10 as an OLED panel as an example, the first substrate 12 and the second substrate 13 can be glass substrates or flexible transparent films, and the layers therebetween include an electrode layer, an organic light-emitting layer, and the like.

[0043] Taking the display panel 10 as a Micro-LED panel as an example, the first substrate 12 can be a glass substrate, a silicon substrate, etc., the second substrate 13 can be a transparent protective film, and the various layers of structure between the two include an electrode layer, a micro light-emitting diode chip, etc.

[0044] The adhesive member 20 is disposed on the surface of the first substrate 12 facing away from the second substrate 13. The adhesive member 20 may be a double-sided adhesive or a double-sided foam adhesive, which plays a role of buffering and fixing.

[0045] The bottom frame 30 is bonded to the adhesive member 20. The structure of the bottom frame 30 is not limited, and the bottom frame 30 plays a supporting role.

[0046] The edging member 40 surrounds the side surfaces of the first substrate 12, the bottom frame 30 and the adhesive member 20. One end of the edging member 40 is connected to the surface of the bottom frame 30 facing away from the first substrate 12, and the other end facing away is connected to the surface of the first substrate 12 facing away from the adhesive member 20. The edging member 40 is spaced apart from the side surfaces of the second substrate 13.

[0047] The edge wrapping member 40 may be an adhesive structure that is opaque or has a relatively low light transmittance. For example, the edge wrapping member 40 may be a black or gray edge wrapping tape. The edge wrapping member 40 wraps the bottom frame 30, the first substrate 12, and the adhesive member 20. Since the plane size of the first substrate 12 is larger than the plane size of the second substrate 13, that is, the edge of the first substrate 12 is the side of the display panel 10, the wrapping effect of the edge wrapping member 40 can fully protect and fix the side of the display panel 10.

[0048] The fixing glue 50 fills the gap between the edging member 40 and the side of the second substrate 13, and bonds the first substrate 12, the second substrate 13 and the edging member 40. The fixing glue 50 is a glue with strong bonding performance, such as UV glue, hot melt glue, epoxy glue, etc. The fixing glue 50 plays a role in bonding reinforcement, so that the edging member 40 forms a stable bonding and fixing effect with the first substrate 12 and the second substrate 13. Optionally, the material of the fixing glue 50 is a black or gray material that is opaque or has low light transmittance, which plays a light-shielding role.

[0049] The edging member 40 and the reinforcement member both have a shading effect, which can prevent the light emitted by the display panel 10 from being emitted from the side of the display panel 10, avoid light efficiency loss and light leakage defects, and improve the light efficiency of the display panel 10, that is, the light emitting surface, that is, the side of the second substrate 13 facing away from the first substrate 12.

[0050] In the embodiment of the present application, the second substrate 13 is set to be retracted relative to the four edges of the first substrate 12, and an adhesive member 20 is set on the surface of the first substrate 12 facing away from the second substrate 13, the bottom frame 30 is bonded to the adhesive member 20, and then the edging member 40 is used to surround the side of the first substrate 12, the bottom frame 30 and the adhesive member 20, so that the edging member 40 wraps the side of the display panel 10 to form a complete protection and fixation, and the first substrate 12, the second substrate 13 and the edging member 40 are bonded and reinforced by setting a fixing glue 50, thereby enhancing the firmness of the edging and improving the appearance and visual effect of the edge of the display panel 10. The display module of the embodiment of the present application can have a narrow frame width and a lower risk of peeling and edge breakage.

[0051] The assembly order of the display module of the embodiment of the present application can be as follows: the display panel 10 and the bottom frame 30 are first assembled and pre-fixed with the adhesive member 20; the edging member 40 is wrapped around the first substrate 12, the bottom frame 30 and the adhesive member 20, wherein the two ends of the edging member 40 are respectively bonded to the surface of the first substrate 12 facing away from the adhesive member 20 and the surface of the bottom frame 30 facing away from the adhesive member 20; one end of the edging member 40 is located on the outside of the second substrate 13 and has a spacing distance from the second substrate 13; then, a fixing glue 50 is applied to the gap between the side surfaces of the edging member 40 and the second substrate 13 on the first substrate 12, so that the fixing glue 50 is bonded to the first substrate 12, the second substrate 13 and the edging member 40 after curing.

[0052] In one embodiment, please refer to Figure 1 , the adhesive member 20 is arranged at the edge of the first substrate 12. Specifically, the adhesive member 20 can be bonded to the edges of the surface of the first substrate 12 facing away from the second substrate 13 to form a ring; the adhesive member 20 can also be bonded to the two opposite edges of the surface of the first substrate 12 facing away from the second substrate 13 to form two parallel strips.

[0053] The bottom frame 30 includes a connecting portion 31, a transition portion 32, and a supporting portion 33 connected in sequence. The connecting portion 31 is bonded to the adhesive member 20, the transition portion 32 and the supporting portion 33 extend toward the middle of the first substrate 12, the distance between the transition portion 32 and the first substrate 12 gradually increases from the connecting portion 31 to the supporting portion 33, the supporting portion 33 and the first substrate 12 are spaced apart, and an accommodating space 35 is formed between the first substrate 12 and the supporting portion 33.

[0054] The connecting portion 31, the transition portion 32 and the supporting portion 33 may be an integral structure, or may be connected to form a whole by welding, bonding, etc. The bottom frame 30 may be a frame structure, such as a rod or plate, etc., which are not limited. The bottom frame 30 may be a symmetrical structure, such as Figure 1 As shown, the bottom frame 30 is a mirror-symmetrical structure in the left-right direction, that is, the two opposite sides of a support portion 33 are respectively connected to the transition portion 32 and the connecting portion 31. The connecting portions 31 on both sides are respectively bonded to an adhesive member 20, and a edging member 40 and a fixing glue 50 are respectively provided on both sides.

[0055] The connecting portion 31 is in close contact with the adhesive member 20 , and the opposing surfaces of the connecting portion 31 and the first substrate 12 are roughly parallel. The thickness of the adhesive member 20 is roughly the same everywhere, so that the connecting portion 31 and the first substrate 12 are stably bonded and fixed by the adhesive member 20 .

[0056] There is an inclined angle between the transition portion 32 and the connecting portion 31, such that a receiving space 35 is formed between the supporting portion 33 and the first substrate 12. The inclined angle is not limited, for example, 90°, 120°, 135°, 150°, etc. The supporting portion 33 can be arranged parallel to the connecting portion 31, such that the supporting portion 33 is parallel to the first substrate 12, so that the receiving space 35 has substantially the same depth at positions corresponding to the supporting portion 33, which facilitates the setting of other devices with uniform thickness in the receiving space 35. For example, for liquid crystal display, a backlight module can be arranged in the receiving space 35 to provide backlight for the liquid crystal panel. Of course, for other types of display technologies, devices such as driving chips can also be arranged in the receiving space 35, and the supporting portion 33 forms a supporting effect on the devices in the receiving space 35.

[0057] Optionally, one end of the connecting portion 31 facing away from the transition portion 32 can extend beyond the first substrate 12, and the corresponding adhesive member 20 can also extend beyond the first substrate 12. Then, the edge wrapping member 40 protrudes outward relative to the corresponding first substrate 12 at positions corresponding to the connecting portion 31 and the adhesive member 20. With such an arrangement, when the side of the display module is bumped, the bumped position is the position of the connecting portion 31, and the first substrate 12 will not be damaged, which can enhance the protection effect on the display panel 10.

[0058] Optionally, please refer to Figure 1 and Figure 2 , the edge wrapping member 40 includes a bottom edge portion 41, a side edge portion 42, and a top edge portion 43 connected in sequence. The bottom edge portion 41 is bonded to the surface of the bottom frame 30 facing away from the first substrate 12, the side edge portion 42 is bonded to the side surfaces of the adhesive member 20 and the bottom frame 30, and the top edge portion 43 is bonded to the surface of the first substrate 12 facing away from the bottom frame 30.

[0059] Specifically, the bottom edge portion 41 is bonded to the surface of the connecting portion 31 of the bottom frame 30 facing away from the adhesive member 20, and the top edge portion 43 is bonded to the surface of the first substrate 12 facing away from the adhesive member 20. The bottom edge portion 41, the side edge portion 42, and the top edge portion 43 are of an integral structure, and the overall cross-section of the three forms a "C" shape.

[0060] Optionally, please refer to Figure 1 , the side edge portion 42 is bonded to the side surfaces of the connecting portion 31, the adhesive member 20, and the first substrate 12. In this way, the edge wrapping member 40 can be stably bonded and the frame width is relatively narrow.

[0061] Optionally, please refer to Figure 2The adhesive member 20 includes a first adhesive portion 21 and a second adhesive portion 22. The first adhesive portion 21 is disposed on the surface of the first substrate 12 facing away from the second substrate 13 and extends to the edge of the first substrate 12. The second adhesive portion 22 is disposed on the side of the first substrate 12 and adheres to the first adhesive portion 21. The side portion 42 adheres to the surface of the second adhesive portion 22 facing away from the first substrate 12. In this way, the second adhesive portion 22 can play a buffering role when the side of the display module encounters bumps.

[0062] Optionally, the top edge portion 43 is also bonded to the surface of the second bonding portion 22 facing away from the bottom frame 30. This can make the adhesive member 20 and the edge member 40 more stably bonded, reduce the gap between the side edge portion 42 and the side of the first substrate 12, and make the structure more stable.

[0063] Please refer to Figure 1 , Figure 2 and Figure 4 A groove 44 is formed on the surface of the top edge portion 43 facing away from the first substrate 12. By forming the groove 44, after the fixing glue 50 is provided, the fixing glue 50 can be accommodated in the groove 44, and the fixing glue 50 can have a larger contact area with the top edge portion 43, thereby having a greater bonding force, so that the fixing glue 50 enhances the bonding and fixing effect on the first substrate 12, the second substrate 13 and the edge member 40.

[0064] Please refer to Figure 1 and Figure 2 The fixing glue 50 includes a filling portion 51 and a covering portion 52 . The filling portion 51 fills the gap between the edging member 40 and the side surface of the second substrate 13 . The covering portion 52 is connected to the filling portion 51 and covers the surface of the edging member 40 facing away from the first substrate 12 .

[0065] There is a gap between the side surface of the second substrate 13 and the side surface of the top edge portion 43, and the glue can flow in an orderly manner during glue injection, that is, the glue first fills the gap, and then the glue injection continues so that the glue overflows the gap and flows onto the top edge portion 43, which is conducive to obtaining more glue injection time and facilitating obtaining better flatness of the fixing glue 50, so that the display module has a better appearance visual effect and display effect.

[0066] When the top edge portion 43 has no groove 44, the covering portion 52 covers the surface of the top edge portion 43 facing away from the first substrate 12. When the top edge portion 43 has a groove 44 on the surface facing away from the first substrate 12, the covering portion 52 is at least partially located in the groove 44.

[0067] During assembly, glue is injected into the gap between the side of the second substrate 13 and the side of the top edge 43. The height of the top edge 43 is lower than the height of the second substrate 13. The liquid glue fills the gap and overflows from the surface of the top edge 43 facing away from the first substrate 12. The amount of glue injected is controlled so that a certain amount of glue is formed on the top edge 43. The cured glue forms a filling portion 51 and a covering portion 52 respectively.

[0068] It is understandable that, based on the first substrate 12 , the height of the covering portion 52 should not be higher than the height of the second substrate 13 to avoid glue overflowing to the surface of the second substrate 13 facing away from the first substrate 12 and causing a poor appearance.

[0069] Please refer to Figure 1 , Figure 2 and Figure 4 , there are multiple grooves 44, and the width and depth of the multiple grooves 44 gradually increase from the side of the second substrate 13 to the side of the first substrate 12. Exemplarily, Figure 4 It is shown that the groove 44 includes a first groove 441, a second groove 442 and a third groove 443 which are sequentially opened from the side of the second substrate 13 to the outside, and the width and depth of the first groove 441, the second groove 442 and the third groove 443 are increased in sequence. Of course, the number of the grooves 44 is not limited to 3, and can also be 2, 4, 5, etc., without limitation. The process of opening the grooves 44 can be any feasible method, without limitation.

[0070] Such a configuration can better control the efficiency of glue injection, that is, when the glue overflows to the surface of the top edge portion 43 facing away from the first substrate 12, the glue flows outward from the side of the second substrate 13 in sequence and fills the first groove 441, the second groove 442 and the third groove 443 in sequence. Since the width and depth of the first groove 441 are small and the volume is small, the width and depth of the second groove 442 are moderate and the volume is moderate, and the width and depth of the third groove 443 are large and the volume is large, the time for the glue to fill the first groove 441, the second groove 442 and the third groove 443 increases in sequence. Setting the groove 44 to such a structure can facilitate the control of the glue injection time, and the covering portion 52 formed after the glue injection is completed and solidified can have a better connection and fixing effect to prevent the edge member 40 from detaching.

[0071] The fixing glue 50 may be a low-reflective black glue, and the corresponding edging piece 40 may have a black woven texture or a matte black texture. In this way, there is a better side light leakage prevention effect and a consistent border appearance visual effect.

[0072] Please refer to Figure 1The display module further includes a first functional layer 11 and a second functional layer 14. The first functional layer 11 is disposed on the surface of the first substrate 12 facing away from the second substrate 13, and the second functional layer 14 is disposed on the surface of the second substrate 13 facing away from the first substrate 12. With the first substrate 12 as a reference, the height of the fixing glue 50 is lower than the height of the second functional layer 14.

[0073] For different display panels 10 , the first functional layer 11 and the second functional layer 14 may be different film layers.

[0074] Taking the display panel 10 as a liquid crystal panel as an example, the first functional layer 11 and the second functional layer 14 may be polarizers. Taking the display panel 10 as an OLED panel as an example, the first functional layer 11 may be a protective foam, and the second functional layer 14 may be a polarizer. Taking the display panel 10 as a Micro-LED panel as an example, the first functional layer 11 may be a protective foam, and the second functional layer 14 may be a glare protection film. Of course, the first functional layer 11 and the second functional layer 14 may also be other types of film layers, without limitation.

[0075] In the embodiment of the present application, after the first functional layer 11, the first substrate 12, the second substrate 13 and the second functional layer 14 are assembled into the whole of the display panel 10, the display panel 10 is then installed with the bottom frame 30, the adhesive 20, the edging member 40 and the fixing glue 50. The first functional layer 11 should be retracted relative to the first substrate 12, and the side of the first functional layer 11 can be bonded to the side of the adhesive 20, or there can be a spacing distance. The side of the second functional layer 14 can be flush with the side of the second substrate 13, or it can be not flush. The width of the first functional layer 11 can be smaller, equal to or larger than the width of the second substrate 13, etc., without limitation. Figure 1 The illustrated embodiment shows that the side surface of the second functional layer 14 is flush with the second substrate 13. In this embodiment, the surface of the second functional layer 14 facing away from the second substrate 13 should be treated with low reflection to reduce visual reflection and enhance the visual effect of edge transition.

[0076] Taking the first substrate 12 as a reference, the height of the fixing glue 50 is lower than the height of the second functional layer 14. Compared with the height of the fixing glue 50 being lower than the height of the second substrate 13, the height of the fixing glue 50 is higher, so that the size of the fixing glue 50 is larger, which can have a better effect on the connection stability.

[0077] In one embodiment, please refer to Figure 2 ,and Figure 1 The embodiments are basically the same, except that the second functional layer 14 also covers the fixing glue 50 .

[0078] When assembling the display module of the present embodiment, the second functional layer 14 of the display panel 10 may not be assembled with the second substrate 13 first. Instead, after assembling other components, the second functional layer 14 is covered on the second substrate 13 and the fixing glue 50 on the four edges is covered. In this way, the fixing glue 50 can play a role in bonding and fixing the second functional layer 14, thereby improving the fixing effect. At the same time, since the second functional layer 14 blocks the fixing glue 50, the frame consistency of the display module can be better, thereby achieving a better visual effect.

[0079] Optional, please refer to Figure 2 and Figure 3 , a shading portion 141 is provided at the position of the second functional layer 14 corresponding to the fixing glue 50. The shading portion 141 can be formed by screen printing black or gray ink. Of course, the shading portion 141 can also be formed by other methods. The shading portion 141 can be provided on the surface of the second functional layer 14 facing the second substrate 13, and the position corresponds to the position of the fixing glue 50 and is located in the non-display area of ​​the display panel 10. This application does not limit the non-display area, and any prior art can be referred to. In this way, the shading portion 141 can shield the fixing glue 50 and enhance the visual effect of the appearance.
