Description

Technical Field

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

[0002] With the innovation and development of folding technology, the demand for thinning and weight reduction of folding mobile phones is becoming stronger and stronger, and more and more new materials are applied to folding modules. Carbon fiber is used as a low-density material in folding modules as a back support material to reduce the weight of the folding modules.

[0003] However, bright / dark ripples (mura) are formed in the bending area, which affects the display effect of the folding module. Summary of the invention

[0004] Based on this, it is necessary to provide a display panel and a display device that can improve display uniformity in order to solve the above technical problems.

[0005] In a first aspect, the present disclosure provides a display panel, wherein the display module comprises:

[0006] A display panel, the display panel having a bending area, a first non-bending area, and a second non-bending area distributed along a first direction, the bending area being located between the first non-bending area and the second non-bending area;

[0007] A carbon fiber layer, disposed on the back of the display panel;

[0008] An electrostatic release layer, comprising a plurality of electrostatic release portions arranged along the first direction, the plurality of electrostatic release portions being arranged at intervals and connected to a fixed potential signal, at least one of the electrostatic release portions being located in the first non-bending area, and at least one of the electrostatic release portions being located in the second non-bending area;

[0009] The conductive layer is at least partially located in the bending area and is electrically connected to the electrostatic release layer. The conductive layer is arranged between the electrostatic release layer and the carbon fiber layer, or the conductive layer is arranged between two adjacent electrostatic release parts.

[0010] The above display module sets a conductive layer on the side of the carbon fiber layer away from the display panel, and shields the electric field or conducts static electricity through the conductive layer, thereby preventing the bending area that cannot be covered by the static release layer from being affected by the electric field and avoiding the problem of bright / dark ripples in the bending area.

[0011] In one embodiment, at least a portion of at least one of the electrostatic release portions is located in the bending region.

[0012] In one embodiment, the conductive layer is disposed between two adjacent electrostatic release portions, and the conductive layer and the carbon fiber layer are detachably connected so that the conductive layer can be removed before assembling the display module;

[0013] Preferably, the conductive layer is copper foil.

[0014] In this way, on the one hand, the conductive layer and the electrostatic release layer are connected to form a whole electric field shielding layer, and the conductive layer can shield the electric field in the bending zone to prevent the bending zone from being affected by the external electric field; on the other hand, the conductive layer and the carbon fiber layer are detachably connected, and the conductive layer can be removed before the display module is assembled, which can avoid the poor bending performance of the conductive layer affecting the bending effect of the display module.

[0015] In one embodiment, the conductive layer is disposed between two adjacent electrostatic release portions, and the thickness of the conductive layer is the same as or less than the thickness of the electrostatic release portion;

[0016] The material of the conductive layer includes stainless steel alloy or titanium alloy.

[0017] In this way, on the one hand, the conductive layer and the electrostatic release layer are connected to form a whole electric field shielding layer. The conductive layer can consume static electricity and prevent the bending area from being affected by the electric field. On the other hand, the conductive layer has good bendability. The conductive layer can bend together with the bending area of ​​the display panel without removing the conductive layer, and the production of the display module is simpler.

[0018] In one embodiment, the thickness of the conductive layer is 20 μm to 30 μm.

[0019] In this way, the conductive layer is thin and has good bending performance, which can prevent the conductive layer from shifting when the bending zone is bent.

[0020] In one embodiment, the thickness of the conductive layer is 30 μm to 150 μm, and a plurality of first holes arranged at intervals are formed in the conductive layer;

[0021] Preferably, the first hole is in the shape of a rhombus, a circle, an ellipse or a rectangle;

[0022] Preferably, the diameter of the first hole is 2 mm to 10 mm;

[0023] Preferably, the spacing between the first holes is 0.3 mm to 1 mm.

[0024] In this way, setting the first hole in the conductive layer can increase the bending performance of the conductive layer, avoid bending of the bending zone and cause the conductive layer to break, thereby increasing the thickness of the conductive layer and improving the effect of the conductive layer in shielding the electric field, thereby avoiding the display panel from being affected by the electric field and avoiding the problem of bright / dark ripples in the bending zone.

[0025] In one embodiment, the conductive layer is disposed between the carbon fiber layer and the electrostatic release layer, and the orthographic projection formed by the conductive layer on the display panel is at least partially located in the bending area;

[0026] Preferably, the orthographic projection formed by the conductive layer on the display panel covers the bending area;

[0027] Preferably, the conductive layer is made of stainless steel alloy or titanium alloy;

[0028] Preferably, the thickness of the conductive layer is 20 μm to 30 μm.

[0029] In this way, a conductive layer is added between the carbon fiber layer and the electrostatic release layer, and the bending area is covered by the conductive layer to prevent the bending area from being affected by the electrostatic electric field, thereby avoiding the problem of bright / dark ripples in the bending area of ​​the display panel.

[0030] In one of the embodiments, at least one side edge of the orthographic projection formed by the conductive layer on the display panel extends beyond a preset length of the edge of the orthographic projection formed by the carbon fiber layer on the display panel;

[0031] Preferably, the preset length is 0.05mm-0.15mm;

[0032] Preferably, the preset length is 0.1 mm.

[0033] In this way, static electricity can be easily discharged through the edge of the conductive layer, thereby preventing static electricity from interfering with the display panel.

[0034] In one embodiment, the display module further includes:

[0035] The conductive silver paste layer is arranged at the edge of the conductive layer.

[0036] In this way, the conductive silver paste layer has a good conductive effect, so that the conductive silver paste layer can connect the film layers on the back of the display panel together, and conduct static electricity on the back of the display panel to improve the antistatic effect of the display module and prevent the display panel from being affected by static electricity.

[0037] In a second aspect, the present disclosure further provides a display device, which includes the display module in the first aspect.

[0038] The above-mentioned display device arranges a conductive layer on the side of the carbon fiber layer away from the display panel, and shields the electric field or conducts static electricity through the conductive layer, thereby preventing the bending area that cannot be covered by the static release layer from being affected by the electric field and avoiding the problem of bright / dark ripples in the bending area.

[0050] In order to facilitate the understanding of the present disclosure, the present disclosure will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present disclosure are given in the drawings. However, the present disclosure can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present disclosure more thorough and comprehensive.

[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present disclosure. The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0052] When describing positional relationships, unless otherwise specified, when an element such as a layer, film, or substrate is referred to as being "on" another element, it can be directly on the other element or there can be intervening elements. Further, when a layer is referred to as being "under" another layer, it can be directly below or there can be one or more light-emitting units. It is also understood that when a layer is referred to as being "between" two layers, it can be the only layer between the two layers or there can be one or more light-emitting units.

[0053] In the case of using “including”, “having”, and “comprising” described herein, another component may be added unless a clear limiting term such as “only”, “consisting of”, etc. is used. Unless mentioned otherwise, a term in the singular form may include a plural form and should not be understood as being one in number.

[0054] It should be understood that although the terms "first", "second", etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. For example, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element without departing from the scope of the present disclosure.

[0055] It should also be understood that when interpreting an element, even if not explicitly described, the element is interpreted as including a range of error, which should be within the acceptable deviation range of the specific value determined by those skilled in the art. For example, "approximately", "approximately" or "substantially" can mean within one or more standard deviations, which are not limited here.

[0056] Furthermore, in the specification, the phrase “planar distribution schematic diagram” refers to a drawing when a target portion is viewed from above, and the phrase “cross-sectional schematic diagram” refers to a drawing when a section taken by vertically cutting the target portion is viewed from the side.

[0057] In addition, the drawings are not drawn to a 1:1 scale, and the relative sizes of the elements in the drawings are drawn only as examples and not necessarily according to the true scale.

[0058] As described in the background technology, the display module in the related technology uses a carbon fiber layer as the supporting material on the back of the display module. Since the carbon fiber layer is not conductive, it is necessary to set an electrostatic release layer on the back of the carbon fiber layer to release the static electricity of the display panel. The electrostatic release layer is usually copper foil. Since the bending ability of copper foil is poor, the copper foil is set in sections in the related technology. The copper foil is only set in the non-bending area, resulting in no copper foil in the bending area. The bending area is easily disturbed by the external electric field, and light / dark ripples are easily generated in the bending area, affecting the display effect of the display module and the user experience.

[0059] Based on the above reasons, the present disclosure provides a display module and a display device, which provides a conductive layer on the side of the carbon fiber layer away from the display panel, and shields the electric field or conducts static electricity through the conductive layer, thereby preventing the bending area that is not covered by the electrostatic release layer from being affected by the electric field, and avoiding the problem of bright / dark ripples in the bending area.

[0060] In a first aspect, the embodiment of the present disclosure provides a display module 10, which may include a flexible display module having only a display function, or a flexible display module having a touch function. The flexible display module may be, for example, a flexible OLED (Organic Light-Emitting Diode) display module, a flexible liquid crystal display module (LCD), or other types of flexible display modules.

[0061] Specifically, refer to Figure 1-Figure 8 As shown, the display module 10 includes a display panel 11, a carbon fiber layer 12, an electrostatic release layer 13 and a conductive layer 14. Among them, the display panel 11 can be flexible polyimide (PI), rigid glass or a thin metal sheet. The embodiment of the present disclosure will not discuss the display panel 11 of other materials in detail. Those skilled in the art can choose different types of materials according to actual needs. The display panel 11 includes a light-emitting side and a backlight side. The light-emitting side is the front side of the display panel 11, and the backlight side is the back side of the display panel 11.

[0062] The display panel 11 has a bending area 113, a first non-bending area 111 and a second non-bending area 112 distributed along a first direction, and the bending area 113 is located between the first non-bending area 111 and the second non-bending area 112; the carbon fiber layer 12 is arranged on the back of the display panel 11; the electrostatic release layer 13 includes a plurality of electrostatic release parts 131 arranged along the first direction, the plurality of electrostatic release parts 131 are arranged at intervals and connected to a fixed potential signal, at least one electrostatic release part 131 is located in the first non-bending area 111, and at least one electrostatic release part 131 is located in the second non-bending area 112; the conductive layer 14 is at least partially located in the bending area 113 and is electrically connected to the electrostatic release layer 13, the conductive layer 14 is arranged between the electrostatic release layer 13 and the carbon fiber layer 12, or, the conductive layer 14 is arranged between two adjacent electrostatic release parts 131.

[0063] In this embodiment, refer to Figure 2 or Figure 5 , fold the display module 10 to bend the bending area 113, the first non-bending area 111 can be parallel to or attached to the second non-bending area 112, unfold the display module 10 to restore the bending area 113 to a straight state, and the first non-bending area 111, the bending area 113 and the second non-bending area 112 are located in the same plane. When folding the display module 10 to bend the bending area 113, fold the display module 10 toward the light-emitting side, and when unfolding the display module 10 to restore the bending area 113 to a straight state, unfold the display module 10 toward the backlight side.

[0064] The carbon fiber layer 12 is disposed on the back of the display panel 11. The carbon fiber layer 12 has the characteristics of high strength and low density. The carbon fiber layer 12 supports the display panel 11 and can meet the supporting strength and bending performance of the display panel 11. At the same time, it can reduce the weight of the display module 10, so that the display module 10 is lighter and thinner, which is beneficial to improving the user experience.

[0065] The electrostatic release layer 13 is disposed on a side of the carbon fiber layer 12 away from the display panel 11. The electrostatic release layer 13 is connected to a fixed potential signal for releasing static electricity on the back of the display panel 11. The material of the electrostatic release layer 13 includes a metal material with good conductivity. In one example, the electrostatic release layer 13 is copper foil.

[0066] The bending performance of the electrostatic release layer 13 is poor. In this embodiment, the electrostatic release layer 13 is arranged in sections, the electrostatic release layer 13 is disconnected at least at the bending area 113, and the electrostatic release layer 13 is arranged into a plurality of electrostatic release portions 131 arranged at intervals along the first direction, and the first non-bending area 111 and the second non-bending area 112 are respectively provided with at least one electrostatic release portion 131 for drawing out static electricity. The electrostatic release layer 13 is prevented from bending with the display panel 11, and the electrostatic release layer 13 is prevented from affecting the folding of the display module 10, and the folding of the display module 10 is prevented from causing the electrostatic release layer 13 to break and affect the service life of the display module 10.

[0067] The conductive layer 14 is at least partially located in the bending area 113 and is electrically connected to the electrostatic release layer 13. The conductive layer 14 is disposed between the electrostatic release layer 13 and the carbon fiber layer 12, or the conductive layer 14 is disposed between two adjacent electrostatic release portions 131. In one example, the conductive layer 14 is disposed between the electrostatic release layer 13 and the carbon fiber layer 12. In another example, the conductive layer 14 is disposed between two adjacent electrostatic release portions 131.

[0068] The display module 10 adds a conductive layer 14 on the side of the carbon fiber layer 12 away from the display panel 11, and shields the electric field or conducts static electricity through the conductive layer 14, thereby preventing the bending area 113 that is not covered by the static release layer 13 from being affected by the electric field, thereby avoiding the problem of bright / dark ripples in the bending area 113.

[0069] In one embodiment, at least a portion of at least one electrostatic release portion 131 is located in the bending zone 113. The electrostatic release portion 131 of the first non-bending zone 111 may extend to the bending zone 113, or the electrostatic release portion 131 of the second non-bending zone 112 may extend to the bending zone 113. However, the electrostatic release portion 131 of the first non-bending zone 111 and the electrostatic release portion 131 of the second non-bending zone 112 are not connected, and there is still an area in the bending zone 113 that is not covered by the electrostatic release portion 131.

[0070] In one embodiment, referring to Figure 1 , Figure 2 The conductive layer 14 is disposed between two adjacent electrostatic release portions 131 , and the conductive layer 14 and the carbon fiber layer 12 can be detachably connected, so that the conductive layer 14 can be removed before the display module 10 is assembled.

[0071] In this way, on the one hand, the conductive layer 14 and the electrostatic release layer 13 are connected to form a whole electric field shielding layer, and the conductive layer can shield the electric field of the bending zone 113 to prevent the bending zone 113 from being affected by the external electric field; on the other hand, the conductive layer 14 and the carbon fiber layer 12 are detachably connected, and the conductive layer 14 can be removed before the display module 10 is assembled, which can prevent the poor bending performance of the conductive layer 14 from affecting the bending effect of the display module 10.

[0072] Specifically, the conductive layer 14 is copper foil. In this way, the conductive layer 14 and the static discharge unit 131 can be formed in the same manufacturing process, which can reduce the manufacturing consumables for forming the conductive layer 14, reduce the manufacturing difficulty of the display module 10, and thus reduce the manufacturing cost of the display module 10.

[0073] In one example, the entire copper foil is etched to break the entire copper foil to form a plurality of electrostatic release portions 131 and a conductive layer 14 disposed in the bending region. In this way, there is no need to add an additional process for forming the conductive layer 14, which not only reduces the cost but also simplifies the design.

[0074] In the display module 10 of the present embodiment, copper foil is provided as the conductive layer 14 in the bending area 113 between the electrostatic release parts 131. The conductive layer 14 shields the electric field on the back side of the display module 10 before assembly (such as the electric field generated by film sticking or film tearing), and prevents the electric field from interfering with the display panel 11 through the bending area 113 between the electrostatic release parts 131, thereby preventing the bending area 113 between the electrostatic release parts 131 from being affected by the electric field and causing the problem of bright / dark ripples, thereby improving the appearance and display effect of the display module 10 and helping to improve the user experience. The conductive layer 14 of the present embodiment is removed before assembly, so that the module assembled from the display module 10 does not contain the conductive layer 14, and the weight of the module assembled from the display module 10 is minimized, and at the same time, the bending performance of the display module 10 during application is not affected.

[0075] In one embodiment, referring to Figure 3 , Figure 4 , the conductive layer 14 is arranged between two adjacent electrostatic release parts 131, and the thickness of the conductive layer 14 is the same as or less than the thickness of the electrostatic release part 131; the material of the conductive layer 14 includes stainless steel alloy or titanium alloy. In this way, on the one hand, the conductive layer 14 and the electrostatic release layer are connected to form a whole layer of electric field shielding layer, and at the same time, the conductive layer 14 can consume static electricity to prevent the bending area 113 from being affected by the electric field. On the other hand, the bending performance of stainless steel alloy or titanium alloy is better than copper foil, and the conductive layer 14 has good bending properties. The conductive layer 14 can be bent together with the bending area 113 of the display panel 11. There is no need to remove the conductive layer 14, and the display module 10 is simpler to manufacture. At the same time, the conductive layer 14 has good bending properties, which avoids the deformation or displacement of the conductive layer 14 due to repeated bending and unfolding of the display panel 11, which can improve the service life of the display module 10 and the user experience.

[0076] In one example, the thickness of the conductive layer 14 and the electrostatic discharge unit 131 are the same. In another example, the thickness of the conductive layer 14 is smaller than the thickness of the electrostatic discharge unit 131.

[0077] In one embodiment, referring to Figure 3 The thickness of the conductive layer 14 is 20 μm to 30 μm. For example, the thickness of the conductive layer 14 can be 20 μm, 22 μm, 24 μm, 25 μm, 27 μm, 29 μm or 30 μm.

[0078] In this way, the conductive layer 14 is thin and has good bending performance, which can prevent the conductive layer 14 from shifting when the bending area 113 is bent. On the other hand, the thin thickness of the conductive layer 14 can reduce the manufacturing consumables for forming the conductive layer 14, reduce the manufacturing difficulty of the display module 10, and thus reduce the manufacturing cost of the display module 10.

[0079] In one embodiment, referring to Figure 4 , Figure 5 , the thickness of the conductive layer 14 is 30μm to 150μm, and for example, the thickness of the conductive layer 14 can be 30μm, 40μm, 50μm, 60μm, 70μm, 80μm, 90μm, 100μm, 120μm, 140μm or 150μm; a plurality of first holes 141 arranged at intervals are configured in the conductive layer 14. The first hole 141 can be a through hole or a blind hole. It can be understood that a through hole is a hole that penetrates the conductive layer 14, and the depth of the through hole is equal to the thickness of the conductive layer 14; a blind hole is a hole that does not penetrate the conductive layer 14, and the depth of the blind hole is less than the thickness of the conductive layer 14.

[0080] In this way, setting the first hole 141 in the conductive layer 14 can increase the bending performance of the conductive layer 14, and avoid the bending zone 113 being repeatedly bent to cause the conductive layer 14 to break, thereby increasing the thickness of the conductive layer 14 and improving the effect of the conductive layer 14 in shielding the electric field, thereby preventing the display panel 11 from being affected by the electric field and avoiding the problem of bright / dark ripples in the bending zone 113.

[0081] It is understandable that, referring to Figure 4 , Figure 5 The first hole 141 may be a relatively regular hole, for example, the first hole 141 may be a rhombus, a circle, an ellipse or a rectangle; or the first hole 141 may be a triangle, a square, a parallelogram, a regular pentagon, a regular hexagon, a quasi-circle or a quasi-ellipse, etc. The first hole 141 may also be an irregular hole, for example, two adjacent first holes 141 have different sizes and / or shapes. The specific structure of the first hole 141 is not limited in the embodiment of the present disclosure.

[0082] Specifically, the shape of the first hole 141 is rhombus, circle, ellipse or rectangle.

[0083] In this way, on the one hand, the bending performance of the conductive layer 14 can be increased to avoid frequent folding of the display module 10, which may cause deformation or displacement of the conductive layer 14 due to multiple bending of the bending zone 113; on the other hand, the first hole 141 is a regular hole, and it is easy to make the first hole 141 in the conductive layer 14, which can reduce the manufacturing cost of the display module 10.

[0084] Specifically, the diameter of the first hole 141 is 2 mm to 10 mm. For example, the diameter of the first hole 141 can be 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 6 mm, 7 mm, 7.5 mm, 8 mm, 9 mm or 10 mm.

[0085] Specifically, the spacing between the first holes 141 is 0.3 mm to 1 mm. For example, the spacing between the first holes 141 may be 0.3 mm, 0.35 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.65 mm, 0.7 mm, 0.8 mm, 0.9 mm or 1 mm.

[0086] In one example, the shape of the first hole 141 is a rhombus, the diameter of the first hole 141 is 2 mm, and the spacing between the first holes 141 is 0.3 mm. In another example, the shape of the first hole 141 is a circle, the diameter of the first hole 141 is 4 mm, and the spacing between the first holes 141 is 0.5 mm. In another example, the shape of the first hole 141 is an ellipse, the diameter of the first hole 141 is 6 mm, and the spacing between the first holes 141 is 0.7 mm; in another example, the shape of the first hole 141 is a rectangle, the diameter of the first hole 141 is 10 mm, and the spacing between the first holes 141 is 1 mm.

[0087] Specifically, the plurality of first holes 141 of the conductive layer 14 are arranged uniformly. It is understood that "uniform arrangement" means that the distance between any two adjacent first holes 141 is equal. This arrangement can, on the one hand, make the bending degree of the conductive layer 14 more uniform, avoiding frequent bending of the conductive layer 14 and local fracture or breakage; on the other hand, it can make the conductive layer 14 uniformly shield the external electric field, avoiding the electric field interference to the display panel 11 caused by the weak local shielding ability, and avoiding the ripple display defect in the bending area 113.

[0088] In one embodiment, referring to Figure 6 , Figure 7 , Figure 8 The conductive layer 14 is disposed between the carbon fiber layer 12 and the electrostatic release layer 13, and the orthographic projection formed by the conductive layer 14 on the display panel 11 is at least partially located in the bending area 113. In this way, by adding the conductive layer 14, the bending area 113 is covered by the conductive layer 14 to prevent the bending area 113 from being affected by the electrostatic electric field, thereby avoiding the problem of bright / dark ripples in the bending area 113 of the display panel 11.

[0089] In some embodiments, the orthographic projection of the conductive layer 14 on the display panel 11 covers the bending area 113. In this way, the bending area 113 is completely covered by the conductive layer 14, and the bending area 113 has a better anti-static interference capability.

[0090] In some embodiments, the material of the conductive layer 14 includes stainless steel alloy or titanium alloy.

[0091] In one embodiment, the thickness of the conductive layer 14 is 20 μm to 30 μm. In this way, on the one hand, the entire conductive layer 14 has a better effect of shielding static electricity, which can effectively prevent the bending area 113 of the display panel 11 from being affected by static electricity. On the other hand, the thickness of the conductive layer 14 is relatively thin, ensuring that the display module 10 is thin and light.

[0092] In one embodiment, referring to Figure 7 , at least one side edge of the orthographic projection formed by the conductive layer 14 on the display panel 11 extends beyond the edge of the orthographic projection formed by the carbon fiber layer 12 on the display panel 11 by a preset length. In this way, the edge of the conductive layer 14 extends beyond the carbon fiber layer 12, so that static electricity can be conducted out through the edge of the conductive layer 14, thereby preventing static electricity from interfering with the display panel 11 and preventing the problem of bright / dark ripples in the bending area 113 of the display panel 11.

[0093] For example, the preset length is 0.05 mm-0.15 mm. For example, the preset length can be 0.05 mm, 0.07 mm, 0.08 mm, 0.1 mm, 0.11 mm, 0.12 mm, 0.13 mm or 0.15 mm.

[0094] Specifically, the preset length is 0.1 mm.

[0095] It is understandable that one side edge of the conductive layer 14 extends out of the preset length of the carbon fiber layer 12. Alternatively, multiple side edges of the conductive layer 14 extend out of the preset length of the carbon fiber layer 12, for example, two side edges of the conductive layer 14 extend out of the preset length of the carbon fiber layer 12, three side edges extend out of the preset length of the carbon fiber layer 12, or four side edges extend out of the preset length of the carbon fiber layer 12.

[0096] In some other embodiments, referring to Figure 6 , the orthographic projection formed by the conductive layer 14 on the display panel 11 coincides with the orthographic projection formed by the carbon fiber layer 12 on the display panel 11. In this way, the edge of the display panel 11 is flat, so as to facilitate the application and assembly of the display panel 11.

[0097] In some other embodiments, referring to Figure 8The orthographic projection of the conductive layer 14 on the display panel 11 may also fall within the orthographic projection of the carbon fiber layer 12 on the display panel 11 , and the edge of the conductive layer 14 is concave relative to the display panel 11 .

[0098] In one embodiment, referring to Figure 7 , Figure 8 The display module 10 further includes a conductive silver paste layer 21, which is coated on the edge of the conductive layer 14. In this way, the conductive silver paste layer 21 has a good conductive effect, so that the conductive silver paste layer 21 can connect the film layers on the back of the display panel 11 together, and conduct static electricity on the back of the display panel 11, so as to improve the antistatic effect of the display module 10, prevent the display panel 11 from being affected by static electricity, and avoid the problem of bright / dark ripples in the bending area 113.

[0099] In one example, referring to Figure 7 , the edge of the conductive layer 14 extends beyond the preset length of the carbon fiber layer 12, and the conductive silver paste layer 21 is coated on the extended edge of the conductive layer 14. In this way, the conductive silver paste layer 21 can be connected to the film layer on the back of the display panel 11, and the static electricity on the back of the display panel 11 can be discharged through the conductive layer 14, thereby improving the efficiency of discharging static electricity.

[0100] In another example, referring to Figure 8 , the edge of the conductive layer 14 is concave relative to the display panel 11, and the conductive silver paste layer 21 is coated on the concave edge of the conductive layer 14. In this way, on the one hand, the static electricity on the back of the display panel 11 can be conducted out through the conductive silver paste layer 21 to improve the antistatic effect of the display module 10; on the other hand, after coating the conductive silver paste layer 21, the edge of the display panel 11 can be smoothed, so as to facilitate the application and assembly of the display panel 11.

[0101] It is understandable that a conductive glue may be applied on the edge of the conductive layer 14 to replace the conductive silver paste layer 21, and static electricity may be discharged through the back of the conductive glue. In this way, the manufacturing cost of the display module 10 can be further reduced.

[0102] It can be understood that a second hole (not shown in the figure) can be provided in the conductive layer 14 at the position of the bending area 113. The second hole can increase the bending performance of the conductive layer 14 in the bending area 113 to avoid the conductive layer 14 from breaking due to repeated bending of the bending area 113, thereby improving the service life of the display module 10 and the user experience.

[0103] The structure and layout rules of the second holes are the same as those of the first holes 141 , and will not be described in detail here.

[0104] In one embodiment, referring to Figure 1 , Figure 3 , Figure 4 , Figure 6-Figure 8 The display module 10 further includes a polarizer 17 , an optical adhesive layer 18 , a cover plate 19 and a first protective layer 20 which are sequentially arranged on the front surface of the display panel 11 . The first protective layer 20 is attached to a side of the cover plate 19 away from the display panel 11 .

[0105] The display module 10 further includes a support layer 15, which is disposed between the back of the display panel 11 and the carbon fiber layer 12. The support layer 15 may be a resin layer. In this way, the support layer 15 has good support strength and bending performance, and can meet the requirements of the display module 10. For example, the material of the support layer 15 may include at least one of polyethylene terephthalate (PET), polycarbonate (PC), polyimide (PI), and polyarylate (PAR).

[0106] The display module 10 further includes a second protective layer 16 , which is attached to a side of the electrostatic release layer away from the display panel 11 .

[0107] The first protective layer 20 and the second protective layer 16 are used to protect the display module 10 . Before the display module 10 is assembled, the first protective layer 20 and the second protective layer 16 are separated and removed.

[0108] Based on the same inventive concept, the embodiment of the present disclosure further provides a display device (not shown), which includes the display module 10 in the above embodiment.

[0109] It can be understood that the display device in the embodiments of the present disclosure can be an OLED display device, a QLED display device, electronic paper, a mobile phone, a tablet computer, a television, a monitor, a laptop computer, a digital photo frame, a navigator, a wearable device, an Internet of Things device, or any other product or component with a display function, and the embodiments of the present disclosure are not limited to this.

[0110] The above-mentioned display device adds a conductive layer 14 on the side of the carbon fiber layer 12 away from the display panel 11, and shields the electric field or conducts static electricity through the conductive layer 14, thereby preventing the bending area 113 that is not covered by the static release layer 13 from being affected by the electric field and avoiding the problem of bright / dark ripples in the bending area 113.

[0111] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0112] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the patent of the present disclosure shall be subject to the attached claims.
