Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a display module and display device. Background Technology

[0002] Currently, narrow bezel display products are increasingly popular among young people, and the ultra-narrow bezel design of display modules has become a trend. However, due to the requirements of edge routing, the width between the edge of the L-cut position of the display panel and the display area cannot be compressed in the existing narrow bezel design of display modules. However, it can be further compressed by the starting point of the bending part of the display panel to achieve a narrower bezel design.

[0003] However, further compression at the bending point will cause part of the screen at the L-cut position of the display panel to be exposed. The exposed part of the screen has no first back plate support, resulting in a deterioration in the mechanical performance of the screen. Utility Model Content

The first transition groove has a first tangent point near the display area, and the second transition groove has a second tangent point near the display area. The line connecting the first tangent point and the second tangent point is a first connecting line, which is the common external tangent of the first transition groove and the second transition groove.

The third corner corresponds to and covers the first corner, and the fourth corner corresponds to and covers the second corner. The first side of the slot near the display area overlaps with the bending line. The side of the first back plate near the bending portion is designed to be irregularly shaped so that the shape of the first back plate matches the L-cut of the main body. This can better cover the corner of the main body near the bending portion and avoid partial exposure of the L-cut of the main body, which would cause a deterioration in the mechanical performance of the display module.

[0039] 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.

[0040] Please refer to Figure 1 , Figure 1 This is a structure of a display module in the prior art. The display module includes a display area AA and a non-display area NA surrounding the display area AA. The display module includes a display panel 100 and a first back plate 200, etc. The display panel 100 includes a main body 110, a bent portion 120, and a bonding portion 130. The first back plate 200 is disposed on the back side of the main body 110. Figure 1 As shown, at the L-cut position of the display panel 100, the distance A between the first edge L1 of the main body 110 near the bend 120 and the second edge L2 of the display area AA near the bend 120 cannot be compressed because this area has a large number of signal traces. However, the ultra-narrow bezel design can be further achieved by compressing the distance B between the bending line W (the position where the bend 120 begins to bend) and the second edge L2 of the display area AA. However, the existing design of the first backplate 200 and the laser grooving method cannot meet the requirement for further compression of the bending line W, such as... Figure 1 As shown by the dashed line M, the existing laser grooving method for the first back panel 200 is a straight line (along the direction of the bending line W). However, when the bending line W is further compressed towards the display area AA, cutting the first back panel 200 using the existing cutting method will result in the exposure of a portion of the main body 110 near the bend 120 (the exposed portion is as indicated by arrow K). Since the exposed portion lacks the support and protection of the first back panel 200, the mechanical performance of the display module will deteriorate.

[0041] To address the aforementioned problems, this application provides a display module 10, please refer to... Figures 2-4This application provides a structure for a display module 10. The display module 10 includes a display area AA and a non-display area NA located on at least one side of the display area AA. The display area AA is used to display images, while the non-display area NA has metal traces and does not display images. The non-display area NA can be located on one side, both sides, three sides, or surrounding the display area AA; this application does not impose any limitations. The following example, where the non-display area NA surrounds the display area AA, further illustrates the display module 10 of this application.

[0042] The display module 10 includes a display panel 100 and a first backplate 200. The display panel 100 includes a main body 110, a bonding portion 130, and a bending portion 120 connecting the main body 110 and the bonding portion 130. The main body 110 includes a display area AA and a non-display area NA. The bonding portion 130 is used to bond components such as chips and circuit boards. The bonding portion 130 is bent to the back side of the main body through the bending portion 120. The main body 110 has a first corner 101 and a second corner 102 on the side closer to the bending portion 120. The first corner 101 and the second corner 102 are located on opposite sides of the bending portion 120. The first corner 101 is connected to the bending portion 120 through a first transition groove 103, and the second corner 102 is connected to the bending portion 120 through a second transition groove 104. The first transition groove 103 and the second transition groove 104 can reduce the stress when the bending portion 120 is bent, thereby avoiding damage to the film layer during the bending process.

[0043] The first back plate 200 is disposed on the back side of the main body 110 and covers the main body 110 to ensure that the entire main body 110 is supported by the first back plate 200, thus ensuring the mechanical performance of the display module 10. The first back plate 200 has a third corner 201 and a fourth corner 202 on the side closer to the bending portion 120. The third corner 201 corresponds to the first corner 101 and covers the first corner 101. The fourth corner 202 corresponds to the second corner 102 and covers the second corner 102. The above-mentioned coverage means that the orthographic projection of the first corner 101 / second corner 102 in the top view direction is within the orthographic projection range of the third corner 201 / fourth corner 202 in the top view direction, and the orthographic projection of the third corner 201 / fourth corner 202 is greater than or equal to the orthographic projection of the first corner 101 / second corner 102. The first back panel 200 is also provided with a slot 210 on the side near the bending part 120. The slot 210 is located between the third corner 201 and the fourth corner 202, that is, the third corner 201 and the fourth corner 202 are connected by the slot 210. In other words, the edge of the first back panel 200 near the bending part 120 is irregular (non-straight) in shape. The slot 210 includes a first side 211 near the display area AA (that is, the bottom edge of the slot 210). The first side 211 overlaps with the bending line W. The bending line W is located between the main body 110 and the bending part 120. The bending line W is the position where the bending part 120 begins to bend.

[0044] In this application, by providing a slot 210 on the side of the first back plate 200 near the bending portion 120, the edge of the first back plate 200 near the bending area (i.e., the first edge 211) is compressed along the bending line W toward the display area AA, so as to meet the compression of the bending line W in the narrow bezel design. At the same time, it ensures that the third corner 201 of the first back plate 200 can cover the first corner 101 of the main body portion 110, and the fourth corner 202 of the first back plate 200 can cover the second corner 102 of the main body portion 110, so as to avoid the first corner 101 and the second corner 102 of the main body portion 110 being partially exposed, which would lead to a reduction in mechanical performance.

[0045] In some embodiments, please refer to Figure 2 and Figure 4Both the first transition groove 103 and the second transition groove 104 are arc-shaped grooves recessed inward in the direction X from the bent portion 120 toward the main body portion 110, i.e., recessed in the direction toward the display area AA. The recessed arrangement of the first transition groove 103 and the second transition groove 104 toward the display area AA compresses the distance B from the bending line W to the display area AA and reduces the stress on the bent portion 120 during bending. The arc shape of the first transition groove 103 and the second transition groove 104 allows for a smooth transition at the L-cut position and a more uniform stress distribution at the connection between the main body portion 110 and the bent portion 120.

[0046] Please refer to Figure 2 The first transition groove 103 has a first tangent point D1 near the display area AA, and the second transition groove 104 has a second tangent point D2 near the display area AA. The line connecting the first tangent point D1 and the second tangent point D2 is the first connecting line, that is, the first connecting line is the external common tangent of the first transition groove 103 and the second transition groove 104; wherein, the bending line W coincides with the first connecting line, that is, the first connecting line can be used as the bending line W, and the bending portion 120 starts to bend from the first connecting line.

[0047] For further details, please refer to Figures 2-4 On the display panel 100, the connection point between the first corner 101 and the first transition groove 103 is the first connection point D3, and the connection point between the second corner 102 and the second transition groove 104 is the second connection point D4; the line connecting the first connection point D3 and the second connection point D4 is the second connection line, the distance from the second connection line to the display area AA is A, the distance from the bending line W to the display area AA is B, and AB≥0.05mm. To achieve an extremely narrow bezel, this application compresses the bending line W towards the display area AA, thus reducing the distance B. However, the distance A cannot be further compressed due to the signal routing. Therefore, a distance difference exists between the bending line W and the first edge L1 (the second connecting line) of the main body 110 near the bend 120, i.e., AB > 0. This distance difference causes the first corner 101 and the second corner 102 to be exposed between the first edge L1 and the cutting line M when using the existing first backplate 200 cutting method (straight-line cutting along the bending line W), without the support of the first backplate 200. Especially when AB ≥ 0.05 mm, the mechanical performance of the display module 10 is significantly weakened. In this case, the irregularly shaped first backplate 200 of this application can effectively solve the problem of weakened mechanical performance of the display module 10 caused by the compression of the bending line W.

[0048] The distance B from the bending line W to the display area AA is greater than or equal to 0.3mm to ensure a safe distance between the bending area and the display area AA, and to avoid problems such as deformation of the edge of the display area AA due to the bending area being too close to the display area AA during the bending process, which would affect the display effect of the display area AA.

[0049] In some embodiments, please refer to Figures 2-4 The outer edge of the third corner 201 is flush with the outer edge of the first corner 101, and the outer edge of the fourth corner 202 is flush with the outer edge of the second corner 102, so as to ensure that the first corner 101 and the second corner 102 of the main body 110 can be effectively supported by the first back plate 200, while avoiding the first back plate 200 from exceeding the edge of the main body 110 and affecting the size of the display module 10.

[0050] For further details, please refer to Figures 2-4 The main body 110 also includes a first side 105 opposite to the bent portion 120, a second side 106 connecting the first side 105 and the first corner 101, and a third side 107 connecting the first side 105 and the second corner 102. The first back plate 200 also includes a fourth side 203 opposite to the first side 211, a fifth side 204 connecting the fourth side 203 and the third corner 201, and a sixth side 205 connecting the fourth side 203 and the fourth corner 202. The fourth side 203 is flush with the first side 105, the fifth side 204 is flush with the second side 106, and the sixth side 205 is flush with the third side 107. This ensures that the main body 110 as a whole can be effectively supported by the first back plate 200, while preventing the first back plate 200 from extending beyond the edge of the main body 110 and affecting the size of the display module 10.

[0051] Among them, the first corner 101, the second corner 102, the third corner 201 and the fourth corner 202 can be rounded corners. The first side 105 and the second side 106 and the first side 105 and the third side 107 can be transitioned by rounded corners. The fourth side 203 and the fifth side 204 and the fourth side 203 and the sixth side 205 can also be transitioned by rounded corners, but are not limited to these.

[0052] For details, please refer to Figures 5-7 In the cutting process of the display panel 100 and the first back plate 200, the first back plate 200 can first be cut on the side near the bending portion 120. This first cut uses a laser grooving method along a specific route (e.g., Figure 5The dashed line N path replaces the linear laser grooving method in the prior art, so that the grooving structure 210 is formed on the side of the first back plate 200 near the bending part 120. Then, the first back plate 200 after the first cut is attached to the display panel 100 and a second cut is performed. The second cut cuts the outer contours of the display panel 100 and the first back plate 200. Therefore, after the second cut, the outer edge of the third corner 201 is flush with the outer edge of the first corner 101, the outer edge of the fourth corner 202 is flush with the outer edge of the second corner 102, the fourth side 203 is flush with the first side 105, the fifth side 204 is flush with the second side 106, and the sixth side 205 is flush with the third side 107. That is, the outer contours of the display panel 100 and the first back plate 200 are flush. Figure 5 This is a schematic diagram of the first backplate being cut in one operation (200mm). Figure 6 This is a schematic diagram before the second cutting. Figure 7 This is a schematic diagram after the second cutting.

[0053] In the laser cutting process, during a single cut, the cutting line M of the first back plate 200 must extend beyond the edges of the corresponding main body 110 near the bending portion 120 at the first corner 101 and the second corner 102, and also beyond the bending line W, to meet the requirements for cutting accuracy and fit deviation. For details, please refer to... Figure 6 The distance a1 from the cutting line M to the edge of the first corner 101 / second corner 102 of the main body 110 is greater than 0, the distance a2 from the cutting line M to the bending line is greater than 0, and the difference Hh between the distance h between the edge of the first cut groove and the side of the binding part 130 and the distance H between the end of the corresponding first transition groove 103 / second transition groove 104 away from the binding part 130 and the side of the binding part 130 is greater than 0. Furthermore, a1 is greater than 0.05mm, a2 is greater than 0.05mm, and Hh is greater than 0.05mm to meet the requirements of cutting accuracy and fitting deviation.

[0054] In some embodiments, please refer to Figures 3-4The slot 210 also includes a second side 212 and a third side 213 located at opposite ends of the first side 211. The first side 211 is the bottom edge of the slot 210, and the second side 212 and the third side 213 are the two sides of the slot 210. The second side 212 and the third side 213 are connected to the first side 211 to form the slot 210. For example, the slot 210 can be U-shaped. The connection point between the third corner 201 and the second side 212 is the third connection point B1, and the connection point between the fourth corner 202 and the third side 213 is the fourth connection point B2. The distance between the third connection point B1 and the fourth connection point B2 is the opening size C of the slot 210. The opening size C is equal to the length of the second connecting line (i.e., the distance between the first connection point D3 and the second connection point D4). That is, the third connection point B1 overlaps with the first connection point D3, and the fourth connection point B2 overlaps with the second connection point D4. This ensures that the opening size of the slot 210 of the first back plate 200 on the side near the bending part 120 is equal to the distance between the first connection point D3 and the second connection point D4 of the main body 110, thus guaranteeing the reserved space for the bending part 120 and avoiding any impact on the bending part 120.

[0055] For further details, please refer to Figure 4 Both the second side 212 and the third side 213 are arc-shaped edges that are recessed inward from the bending portion 120 toward the main body portion 110, i.e., recessed toward the display area AA; the first transition groove 103 includes a first transition edge 1031 located between the first connection point D3 and the first tangent point D1, and the second transition groove 104 includes a second transition edge 1041 located between the second connection point D4 and the second tangent point D2; wherein, the second side 212 overlaps with the first transition edge 1031, and the third side 213 overlaps with the second transition edge 1041, i.e., the second side 212 is flush with the first transition edge 1031, and the third side 213 is flush with the second transition edge 1041, so as to avoid the first back plate 200 from exceeding the inner arc edge of the first transition groove 103 and the second transition groove 104, which would cause the second side 212 and the third side 213 of the first back plate 200 to affect the bending performance of the bending portion 120.

[0056] In some embodiments, please refer to Figure 4 The first transition groove 103 and the second transition groove 104 are symmetrically arranged about the center line OO' of the display panel 100, and the slot 210 is also symmetrical about the center line OO'. Furthermore, the display panel 100 and the first back plate 200 as a whole can be a symmetrical structure about the center line OO'. The symmetry of the structure can improve the bending performance and stability of the bending part 120 during the bending process, and at the same time simplify the cutting process and improve the cutting accuracy and bonding accuracy. The center line OO' extends along the first direction X, which is the direction from the binding part 130 to the main body part 110.

[0057] In some embodiments, please refer to Figure 8The display module 10 also includes: a second back plate 300, a buffer layer 400, an adhesive layer 500, a protective adhesive layer 600, a polarizer 700, an optical adhesive layer 800, and a cover plate 900. The second back plate 300 is disposed on the side of the bonding portion 130 near the first back plate 200, and the outer contour of the second back plate 300 is flush with the outer contour of the bonding portion 130 (e.g., Figure 7 As shown, the first backplate 200 and the second backplate 300 provide support for the bonding portion 130. The materials of the first backplate 200 and the second backplate 300 can be organic polymer materials, such as polyimide (PI), but are not limited thereto. A buffer layer 400 is disposed between the first backplate 200 and the second backplate 300 to provide a buffering effect. The material of the buffer layer 400 can be flexible foam (Super Clean Foam, SCF), but is not limited thereto. An adhesive layer 500 is disposed between the buffer layer 400 and the second backplate 300 to bond the upper and lower film layers. The material of the adhesive layer 500 can be adhesive or tape. A protective adhesive layer 600 is disposed on the side of the bending portion 120 away from the first backplate 200 and the second backplate 300, and covers the bending portion 120 and the portion of the main body 110 and the bonding portion 130 connected to the bending portion 120, providing protection for the bending portion 120. The material of the protective adhesive layer 600 can be ultraviolet (UV) curable adhesive. A polarizer 700 is disposed on the side of the main body 110 away from the first back plate 200 to improve the display effect. A cover plate 900 is disposed on the side of the polarizer 700 away from the main body 110 to protect the display module 10. An optical adhesive layer 800 is disposed between the polarizer 700 and the cover plate 900 to bond the upper and lower film layers; the material of the optical adhesive layer 800 can be optically clear adhesive (OCA).

[0058] It should be noted that the display module 10 of this application may also include other conventional film layers in the art, and this application does not impose any restrictions.

[0059] This application also provides a display device, which includes the display module 10 as described above. The display device can be a mobile phone, tablet, computer, television, smart display, vehicle display, or other similar products, but is not limited to these.

[0060] This application provides a display module and a display device. The display module includes a display panel and a first back plate. The display panel includes a main body, a bending portion, and a bonding portion. The main body has a first corner and a second corner on the side near the bending portion. The first corner and the second corner are located on opposite sides of the bending portion. The first corner and the bending portion are connected by a first transition groove, and the second corner and the bending portion are connected by a second transition groove. The first back plate has a third corner, a fourth corner, and a slot between the third corner and the fourth corner on the side near the bending portion. The third corner corresponds to and covers the first corner, and the fourth corner corresponds to and covers the second corner. The first side of the slot near the display area overlaps with the bending line. The side of the first back plate near the bending portion is designed to be irregularly shaped so that the shape of the first back plate matches the L-cut of the main body. This can better cover the corner of the main body near the bending portion and avoid partial exposure of the L-cut of the main body, which would cause a deterioration in the mechanical performance of the display module.
