[0032] like Figure 1 As shown, the demand for narrow borders of display modules is becoming increasingly strong. There are many factors that affect the narrow borders of display modules, such as the thickness F and climbing distance C of the protective glue 3, the thickness E of the display panel 1, and the binding radius R. By reducing the binding radius R, the width of the lower border of the display module can be reduced.

[0033] The display module may include a display panel 1, which includes a display portion 11 and a non-display portion 12. The display portion 11 is arranged in the display area of ​​the display panel 1, and the non-display portion 12 includes a first straight portion 121, a first bent portion 122 and a second straight portion 123. The first straight portion 121 is connected to the display portion 11, the first bent portion 122 is adjacent to an end of the first straight portion 121 away from the display portion 11, and the second straight portion 123 is adjacent to an end of the first bent portion 122 away from the first straight portion 121.

[0034] The first straight portion 121 is arranged in the non-display area of ​​the display side of the display module, the first bent portion 122 is bent along the side of the display module to the display panel 1, the second straight portion 123 can be arranged on the non-display side of the display module, the display portion 11 can perform the display function of the display module, and the display portion 11 has a display device, the second straight portion 123 can be provided with a circuit board, the circuit board is connected with a metal trace, the metal trace extends to the display portion 11 through the first bent portion 122, and is connected to the display device.

[0035] A support layer group 2 is provided between the display side and the non-display side of the display panel 1. In order to closely fit the display panel 1 and the support layer group 2 and obtain a good display effect, one end of the display panel 1 after profiling is bonded to the front side of the support layer group 2, and is bent along the side of the support layer group 2 to the back side of the support layer group 2, and the other end of the display panel 1 is bonded to the back side of the support layer group 2. The display portion 11 and the first straight portion 121 are bonded to the front side of the support layer group 2, and the second straight portion 123 is bonded to the back side of the support layer group 2.

[0036] The support layer group 2 includes a first back film 221, a heat dissipation film 222, a spacer layer 223, and a second back film 224 which are sequentially arranged. The heat dissipation film 222 is arranged on one side of the first back film 221, the spacer layer 223 is arranged on the side of the heat dissipation film 222 away from the first back film 221, and the second back film 224 is arranged on the side of the spacer layer 223 away from the first back film 221. The display portion 11 and the first straight portion 121 are attached to the first back film 221, and the second straight portion 123 is attached to the second back film 224.

[0037] The distance between the edge of the first back film 221 and the starting end of the first bending portion 122 is the first distance d1, the first distance d1 is 0, the distance between the edge of the second back film 224 and the ending end of the first bending portion 122 is the second distance d2, the second distance d2 is 0, and the length L of the first bending portion 122 is πR. After the display panel 1 is bent, the first bending portion 122 is smooth without corners, and the length L of the first bending portion 122 is positively correlated with the binding radius R. The actual value of the binding radius R is greater than the design value, and the arcing effect of the first bending portion 122 is deteriorated. Stress concentration occurs during the bending process of the display panel 1, which may cause the risk of binding cracking.

[0038] Based on this, the present disclosure provides a display module. Figures 2 to 8As shown, the display module includes a support layer group 2 and a display panel 1, the support layer group 2 includes a first back film 221 and a second back film 224, the first back film 221 and the second back film 224 are respectively arranged on the front and back of the support layer group 2; the display panel 1 includes a first straight portion 121, a first bent portion 122 and a second straight portion 123, the first straight portion 121 is bonded to the first back film 221, the first bent portion 122 is bent along the side of the support layer group 2 to the back of the support layer group 2, and the second straight portion 123 is bonded to the second back film 224; the distance between the edge of the first back film 221 and the starting end of the first bent portion 122 is a first distance, and the distance between the edge of the second back film 224 and the ending end of the first bent portion 122 is a second distance, and the first distance is greater than the second distance.

[0039] The distance between the edge of the first back film 221 of the display module and the starting end of the first bending portion 122 is a first distance, and the distance between the edge of the second back film 224 and the ending end of the first bending portion 122 is a second distance. The first distance is greater than the second distance, which can reduce or eliminate the influence of binding tolerance and material tolerance on the arc effect of the bending portion, avoid the first back film 221 entering the bending portion to affect the binding radius, make the actual value of the binding radius closer to the design value, and the arc effect of the display panel 1 is better.

[0040] The display module involved in the present disclosure is described in detail below in conjunction with specific embodiments.

[0041] like Figures 2 to 4 As shown, Figure 1 The difference is that the first distance d1 is greater than the second distance d2. Specifically, the second distance d2 can be 0, and the first distance d1 is greater than or equal to 0.1 mm. The length L of the first bending portion 122 is πR+d1. The eccentric design of the first back film 221 and the second back film 224 mainly considers the influence of the bending accuracy a and the incoming material accuracy b to prevent the first back film 221 from entering the first bending portion 122. Generally, the bending accuracy a is ±0.08mm, and the incoming material accuracy b is ±0.06mm, that is, L=πR+0.1mm.

[0042] After the display panel 1 is bent, the first bending portion 122 is smooth without corners, the length L of the first bending portion 122 is positively correlated with R, and the actual value of the binding radius R is greater than the designed value. Figures 2 to 4 and Figure 1 compared to, Figures 2 to 4 The middle binding radius R is closer to the design value, which reduces the influence of process accuracy and material tolerance and prevents the first back film 221 from entering the first bending portion 122 . Figures 2 to 4 The distance from the vertex of the first bending portion 122 to the binding center is small, and the distance between the vertex of the first bending portion 122 and the vertex of the bending portion is small. Figures 2 to 4 The narrow border of the display module is better.

[0043] The display module also includes a polarizing layer 4, which is disposed on the display side of the display panel 1. The orthographic projection of the polarizing layer 4 on the display panel 1 covers the display portion 11 and overlaps with the first straight portion 121. The thickness of the polarizing layer 4 is greater than the thickness of the protective glue 3, so the climbing distance C of the protective glue 3 is relatively large, which will increase the frame of the display module. Therefore, the difference between the thickness of the polarizing layer 4 and the thickness of the protective glue 3 on the first straight portion 121 can be reduced, thereby reducing the climbing distance of the protective glue 3. Figure 3 and Figure 4 In the embodiment, the thickness of the polarizing layer 4 is made equal to the thickness of the protective glue 3 on the first straight portion 121 , and the climbing distance of the protective glue 3 can be removed.

[0044] A protective glue 3 is provided on the side of the non-display portion 12 away from the supporting layer group 2, and the protective glue 3 covers the first bending portion 122, part of the first straight portion 121 and part of the second straight portion 123. During the bending process of the display panel 1, the protective glue 3 can buffer part of the bending stress, form protection for the first bending portion 122, and prevent the display panel 1 from breaking.

[0045] like Figures 5 to 7 As shown, the display module also includes a cover plate 5, which is made of a flexible material. The cover plate 5 may include a second bending portion 51, a third straight portion 52 and a fourth straight portion 53. The third straight portion 52 is bonded to the side of the first straight portion 121 away from the second back film 224 through a first adhesive layer 6, and the fourth straight portion 53 is bonded to the side of the second straight portion 123 away from the first back film 221 through a second adhesive layer 7.

[0046] Usually, the thickness of the first bending portion 122 will also affect the width of the frame of the display module. Therefore, considering reducing the thickness of the first bending portion 122, a first groove 31 is provided on the side of the protective glue 3 away from the first bending portion 122, and the cover plate 5 is fitted in the first groove 31, so that the distance between the outer surface of the cover plate 5 and the first bending portion 122 is reduced, thereby achieving the purpose of reducing the frame of the display module.

[0047] Generally, the thickness of the second bending portion 51 will also affect the width of the frame of the display module. Therefore, in order to reduce the thickness of the second bending portion 51, the second groove 511 may be provided on the side of the second bending portion 51 close to the first bending portion 122, or on the side of the second bending portion 51 far from the first bending portion 122. In order to ensure the beauty of the display module, the second groove 511 is generally provided on the side of the second bending portion 51 close to the first bending portion 122.

[0048] The length of the second groove 511 is greater than that of the first groove 31 to ensure that when the cover plate 5 is fitted with the protective glue 3, the portion of the protective glue 3 located in the first groove 31 can fit with the portion of the second bent portion 51 located in the second groove 511, so that the distance between the outer surface of the cover plate 5 and the first bent portion 122 is further reduced, thereby achieving the purpose of further reducing the frame of the display module.

[0049] like Figure 5 As shown, a simple force analysis of the curved edge of the bonded display module shows that the rebound force of the display panel 1 is an upward force F, that is, the rebound force of the first straight portion 121 is an upward force F; the rebound force of the cover plate 5 after the folding is a downward force F2, that is, the rebound force of the fourth straight portion 53 is a downward force F2, and the tension of the folded portion of the third straight portion 52 is a downward force F3. Because F2 and F3 are in opposite directions to F, they have a mutually offsetting effect. In this way, the debonding phenomenon between the first back film 221 and the heat dissipation film 222 during bending can be eliminated, and the bonding yield of the display panel 1 can be improved.

[0050] The area where the first back film 221 does not overlap with the heat dissipation film 222 is defined as the first area 211. Figure 5 The width of the first region 211 is significantly smaller than Figure 1 The width of the first region 211 in the middle portion is such that the area of ​​the region where the heat dissipation film 222 provides the rebound force becomes smaller when the heat dissipation film 222 is bent. Figure 5 The bending stress is less than Figure 1 The bending stress is Figure 5 The probability of peeling between layers in the display module is less than Figure 1 The probability of peeling between layers in the module is shown in the figure. Figure 5 The layer-to-layer peeling phenomenon of the display module is relatively common. Figure 1 The layer-to-layer peeling phenomenon of the display module is 30% lower.

[0051] The spacer layer 223 in the support layer group 2 may also be provided as an integrated material with the first back film 221, the heat dissipation film 222 and the second back film 224, that is, the support layer group 2 is formed by cutting the pre-formed stack, rather than cutting and stacking the layers of the stack in the process of forming the display module. The precision stability of stacking first and then cutting is better than the precision stability of cutting first and then stacking, which is conducive to improving the phenomenon of peeling between layers in the display module during the bending process.

[0052] The display module needs to bend the display panel 1, so an OLED display panel 1 can be used. Figure 8As shown, the OLED display panel 1 generally includes a driving backplane 101 and a pixel layer. The driving backplane 101 includes a base substrate 1011 and a driving circuit layer 1012. The driving circuit layer 1012 is arranged on one side of the base substrate 1011. The driving circuit layer 1012 includes a plurality of pixel circuits ( Figure 8 (not shown in the figure), the pixel layer is arranged on the side of the driving circuit layer 1012 away from the base substrate 1011, and the pixel layer includes a pixel definition layer 102 and a plurality of light-emitting devices 103.

[0053] The substrate 1011 may be an inorganic substrate 1011 or an organic substrate 1011. For example, in one embodiment of the present disclosure, the substrate 1011 may be made of glass materials such as soda-lime glass, quartz glass, sapphire glass, or may be made of metal materials such as stainless steel, aluminum, and nickel.

[0054] In another embodiment of the present disclosure, the material of the base substrate 1011 can be polymethyl methacrylate (PMMA), polyvinyl alcohol (PVA), polyvinyl phenol (PVP), polyether sulfone (PES), polyimide, polyamide, polyacetal, polycarbonate (PC), polyethylene terephthalate (PET), polyethylene naphthalate (PEN) or a combination thereof.

[0055] In another embodiment of the present disclosure, the substrate 1011 may also be a flexible substrate 1011, for example, the material of the substrate 1011 may be polyimide (PI). The substrate 1011 may also be a composite of multiple layers of materials. For example, in one embodiment of the present disclosure, the substrate 1011 may include a bottom film layer, a pressure-sensitive adhesive layer, a first polyimide layer, and a second polyimide layer stacked in sequence.

[0056] like Figure 8As shown, the pixel definition layer 102 is arranged on the side of the driving circuit layer 1012 away from the base substrate 1011, and a pixel opening 1021 is provided on the pixel definition layer 102. Each light-emitting device 103 can be distributed in an array in the pixel opening 1021. The light-emitting device 103 can be an organic light-emitting diode, which includes a first electrode 1031, a light-emitting material layer 1032 and a second electrode 1033 stacked in a direction away from the base substrate 1011, wherein: a first electrode 1031 is connected to a pixel circuit, and the first electrode 1031 serves as an anode.

[0057] like Figure 8 As shown, the light-emitting material layer 1032 is at least partially disposed in the pixel opening 1021, and the light-emitting material layer 1032 can be distributed in an array, and each light-emitting device 103 has an independently emitting light-emitting material layer 1032, so that each light-emitting device 103 can emit light independently, and the light-emitting colors of different light-emitting devices 103 can be different. For example, the number of the light-emitting material layer 1032 is multiple, and the array is distributed in each pixel opening 1021, and is stacked with the first electrode 1031 exposed by the pixel opening 1021.

[0058] like Figure 8 As shown, the second electrode 1033 may cover the light-emitting material layer 1032, which may serve as a cathode of the light-emitting device 103. Each light-emitting device 103 may share the same second electrode 1033. Specifically, the second electrode 1033 is a continuous conductive layer covering the light-emitting material layer 1032 of each light-emitting device 103 and the pixel definition layer 102. That is, the orthographic projection of the second electrode 1033 on the pixel definition layer 102 covers each pixel opening 1021.

[0059] like Figure 8 As shown, in order to limit the range of each light-emitting device 103, a pixel definition layer 102 may be further provided on the surface of the planarization layer away from the base substrate 1011, and the pixel definition layer 102 may be used to separate each light-emitting device 103, thereby preventing the adjacent light-emitting devices 103 from cross-coloring. Specifically, the pixel definition layer 102 may be provided with a plurality of pixel openings 1021, each pixel opening 1021 correspondingly exposes each first electrode 1031, and the boundary of the pixel opening 1021 is located within the boundary of the exposed first electrode 1031. The range defined by each pixel opening 1021 is the range of a light-emitting device 103.

[0060] The present disclosure also provides a display device, which may include any of the display modules mentioned above. The structure and beneficial effects of the display device may refer to the display module and will not be described in detail here.

[0061] It should be noted that, in addition to the display module, the display device also includes other necessary parts and components, such as a housing, a circuit board, a power cord, etc. Those skilled in the art may make corresponding supplements according to the specific use requirements of the display device, which will not be repeated here.

[0062] The display device can be a traditional electronic device, such as a mobile phone, a watch, a computer, a television, and a camcorder, or it can be an emerging wearable device, such as VR glasses, which are not listed here one by one.
