Description

Technical Field

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

[0002] As the foldable phone market matures, mobile phone terminals are gradually beginning to pursue lighter and thinner devices. As an important component of the entire device, the screen has an increasingly strong demand for thinning.

[0003] At present, the display module of foldable mobile phones is mainly composed of five parts: cover plate, polarizing layer, display panel, back plate layer and module support component (Bracket, BKT). The module support component includes a buffer layer (usually made of PET or PI), an adhesive layer and a metal support layer. Among them, the excessive thinning of the cover plate, polarizing layer, display panel and back plate layer has a significant deterioration effect on the mechanical properties of the front of the module. The thickness of the metal support layer in BKT is usually greater than 120μm, accounting for more than 20% of the thickness of the whole module, and the metal density is high and the weight is large. Thinning the metal support layer in BKT is conducive to the thinness of the module, but the thinning of a single metal support layer in BKT, especially when the thickness of the metal support layer is less than 120μm, will cause problems such as poor appearance of orange grain on the front of the module. Summary of the invention

[0004] The embodiments of the present application provide a display module and a display device, wherein the display module can reduce the thickness while avoiding the problem of poor appearance of orange stripes on the front side of the display module.

[0005] In order to achieve the above object, according to a first aspect of the present application, a display module is provided, comprising:

[0006] Display panel;

[0007] A backplane layer, disposed on one side of the display panel; and

[0008] A support component, disposed on a side of the backplane layer away from the display panel, comprising a flexible support layer and a rigid support layer, wherein the flexible support layer is located between the backplane layer and the rigid support layer;

[0009] The elastic modulus of the flexible support layer is greater than that of the backplane layer and less than that of the rigid support layer, and the thickness of the flexible support layer is less than or equal to 50 μm, and the thickness of the rigid support layer is less than or equal to 120 μm.

[0010] In some embodiments, the elastic modulus of the backplane layer is less than 10 GPa, the elastic modulus of the flexible support layer is 10 GPa to 80 GPa, and the elastic modulus of the rigid support layer is greater than 150 GPa.

[0011] In some embodiments, the thickness of the flexible support layer is 25 μm to 50 μm, and the thickness of the rigid support layer is 20 μm to 120 μm.

[0012] In some embodiments, the material of the flexible supporting layer is ultra-thin flexible glass.

[0013] In some embodiments, the material of the rigid support layer is metal or composite fiberboard.

[0014] In some embodiments, the edge of the flexible supporting layer is set inward relative to the edge of the rigid supporting layer, and the distance between the edge of the flexible supporting layer and the edge of the rigid supporting layer is 0.15 mm to 0.30 mm.

[0015] In some embodiments, the supporting assembly further includes a first bonding layer and a second bonding layer, wherein the first bonding layer is disposed between the back panel layer and the flexible supporting layer, and the second bonding layer is disposed between the flexible supporting layer and the rigid supporting layer, wherein the material of the first bonding layer includes reflective particles.

[0016] In some embodiments, the display panel includes a bending area and non-bending areas located on opposite sides of the bending area; the rigid supporting layer includes a first supporting portion corresponding to the bending area and a second supporting portion corresponding to the non-bending area, and the first supporting portion is provided with a stress release structure.

[0017] In some embodiments, the display module further includes:

[0018] A shell is arranged on a side of the rigid supporting layer away from the flexible supporting layer;

[0019] Frame glue, arranged between the shell and the rigid support layer;

[0020] The area of ​​the flexible supporting layer corresponding to the sealant is located on the same plane as other areas of the flexible supporting layer.

[0021] According to a second aspect of the present application, a display device is provided, comprising the display module as described in the first aspect.

[0022] In the display module and display device provided by the embodiments of the present application, the support component includes a flexible support layer and a rigid support layer, wherein the flexible support layer is located between the rigid support layer and the backplane layer. The position of the flexible support layer of the present application is equivalent to the buffer layer in the module support layer of the prior art. In the prior art, the buffer layer and the backplane layer are both made of PET or PI materials with equivalent elastic moduli, while the elastic modulus of the flexible support layer of the present application is greater than that of the backplane layer. The increase in the elastic modulus of the flexible support layer makes the film layer harder, which can improve the overall support performance and impact resistance of the support component to the outside world. After replacing the existing buffer layer with a flexible support layer with higher hardness, the thickness of the rigid support layer can be reduced accordingly, so that the thickness of the rigid support layer is reduced to less than 120μm, so as to further reduce the thickness of the display module. Therefore, the combination of the flexible support layer and the rigid support layer in the present application can reduce the thickness of the display module while avoiding problems such as poor orange-striped appearance on the front of the display module.

[0023] Other features and advantages of the present application will be described in detail in the subsequent detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0035] See also Figure 1 , Figure 1 A schematic diagram of the cross-sectional structure of a display module provided in the prior art. The display module includes a support assembly 110, a backplane layer 120, a display panel 130, a polarizing layer 140 and a cover plate 150 stacked in sequence. Among them, the support assembly 110 includes a first adhesive layer 113, a buffer layer 101, a second adhesive layer 114 and a metal support layer 102 stacked, and the buffer layer 101 is located between the backplane layer 120 and the metal support layer 102. In the prior art, the material of the backplane layer 120 and the buffer layer 101 is usually a flexible material, such as polyethylene terephthalate (PET) or polyimide (PI), and the elastic modulus of PET or PI material is usually less than 10Gpa. The thickness of the buffer layer 101 is usually 25μm to 50μm.

[0036] In the prior art, after the metal support layer 102 of the folding display module is thinned, the roughness of the metal material surface will increase, and stripes are likely to appear during the metal rolling process. After the metal support layer 102 is bonded to the display module, the adverse deformation of the metal support layer 102 will gradually be transmitted to the film layer above it, and the buffer layer 101 is a flexible PET or PI material, which has insufficient hardness and is easy to deform. The adverse deformation of the metal support layer 102 will be transmitted to the backplane layer 120, the display panel 130 and the film layer above it through the buffer layer 101, causing the front side of the module (i.e., the light-emitting side 103) to have an orange-striped appearance and other problems. Therefore, in the prior art, the thickness of the metal support layer 102 is usually above 120 μm.

[0037] See also Figure 2 , Figure 2 A cross-sectional structural diagram of a display module provided in an embodiment of the present application. The present application provides a display module 100, which can reduce the thickness while avoiding the problem of poor appearance of orange stripes on the front of the display module.

[0038] The display module 100 includes a backplane layer 120, a display panel 130 and a support component 110; the backplane layer 120 is arranged on one side of the display panel 130; the support component 110 is arranged on the side of the backplane layer 120 away from the display panel 130, and includes a flexible support layer 111 and a rigid support layer 112, the flexible support layer 111 is located between the backplane layer 120 and the rigid support layer 112, wherein the elastic modulus of the flexible support layer 111 is greater than the elastic modulus of the backplane layer 120 and less than the elastic modulus of the rigid support layer 112, and the thickness of the flexible support layer 111 is less than or equal to 50μm, and the thickness of the rigid support layer 112 is less than or equal to 120μm.

[0039] The display panel 130 is a flexible display panel 130, which has a bendable or foldable performance. The display panel 130 can be a flexible OLED or a flexible LCD, but is not limited thereto.

[0040] The backplane layer 120 is used to support the display panel 130 and is attached to the side of the display panel 130 that is away from the light emitting surface. The material of the backplane layer 120 is polyethylene terephthalate (PET) or polyimide (PI), etc. The elastic modulus of the backplane layer 120 is less than 10 GPa.

[0041] The support assembly 110 is used to support the backplane layer 120, the display panel 130 and other structures above it. The support assembly 110 serves as the support structure of the entire display module 100 to improve the overall impact resistance of the display module 100 to the outside world. The support assembly 110 includes a flexible support layer 111 and a rigid support layer 112, and the flexible support layer 111 and the rigid support layer 112 can be connected by an adhesive layer. Among them, the elastic modulus of the flexible support layer 111 is greater than the elastic modulus of the backplane layer 120, that is, the hardness of the flexible support layer 111 is greater than the hardness of the backplane layer 120. The flexible support layer 111 is located between the backplane layer 120 and the rigid support layer 112. While playing a certain supporting role, it has a certain hardness to prevent the deformation of the rigid support layer 112 from being transmitted to the film layer above the flexible support layer 111. The elastic modulus of the rigid support layer 112 is greater than that of the back panel layer 120 and the flexible support layer 111, that is, the hardness of the rigid support layer 112 is greater than that of the back panel layer 120 and the flexible support layer 111. The rigid support layer 112 plays a major supporting role and also protects the display panel.

[0042] In the prior art, the materials of the buffer layer 101 and the backplane layer 120 are usually PET or PI, and the elastic modulus of the buffer layer 101 is equivalent to that of the backplane layer 120. In the present application, the buffer layer 101 in the support component 110 of the display module of the prior art is replaced with a flexible support layer 111, and the elastic modulus of the flexible support layer 111 is greater than the elastic modulus of the backplane layer 120, that is, the elastic modulus of the material of the flexible support layer 111 is greater than the elastic modulus of the material (PET or PI) of the buffer layer 101 in the prior art. Therefore, the hardness of the material of the flexible support layer 111 is increased compared with the hardness of the existing buffer layer 101. While increasing the hardness of the flexible support layer 111, the present application also reduces the thickness of the rigid support layer 112, so that the thickness of the rigid support layer is reduced to less than 120μm, so as to reduce the overall thickness of the display module 100 and realize the thinness of the display module 100. Since the hardness of the flexible support layer 111 is improved, the support performance and impact resistance of the support component 110 can be improved, and the undesirable deformation caused by the thinning of the rigid support layer 112 can be resisted, so that the problems such as the poor appearance of the front side of the display module caused by the thinning of the rigid support layer 112 can be improved. Therefore, the display module 100 of the present application can maintain the mechanical properties of the support component 110 while the support component 110 is thinned, and improve the poor appearance problem caused by the thinning of the rigid support layer 112.

[0043] In some embodiments, since the display module 100 is a foldable or bendable display module, the flexible support layer 111 also needs to have a certain elasticity, and the elastic modulus of the material of the flexible support layer 111 is 10Gpa to 80Gpa. The elastic modulus refers to the stress divided by the strain in the direction under the unidirectional stress state. In the elastic deformation stage of the material, its stress and strain become a proportional relationship (i.e., it conforms to Hooke's law), and its proportional coefficient is called the elastic modulus. The elastic modulus is a measure of the material's ability to resist elastic deformation. The elastic modulus can be a tensile elastic modulus. In the present application, the material of the flexible support layer 111 can be an inorganic material or an organic material, but is not limited thereto. When the elastic modulus of the material of the flexible support layer 111 is within the above range, it can satisfy that the flexible support layer 111 has a certain rigidity, and at the same time can satisfy a certain foldable or bendable performance to meet the bending requirements of the display module 100.

[0044] In some embodiments, the material of the flexible support layer 111 may be ultra-thin flexible glass (UTG). Ultra-thin flexible glass (elastic modulus exceeding 70 Gpa) has a higher elastic modulus than PET and PI film materials (elastic modulus less than 10 Gpa), and the higher the elastic modulus, the smaller the deformation, and it is difficult for ultra-thin flexible glass to undergo local deformation. Therefore, the local deformation caused by the thinning of the rigid support layer 112 is difficult to be transmitted to the front of the module through the ultra-thin flexible glass, which can improve the poor orange-strip appearance caused by the thinning of the rigid support layer 112. The hardness of ultra-thin flexible glass is greater than that of PET and PI film materials, so it has better supporting performance and resistance to external impact. Ultra-thin flexible glass is not easy to deform and can resist the surface unevenness problem caused by the thinning of the rigid support layer 112 in the support assembly 110, which can effectively avoid the deterioration of the appearance of the front of the display module.

[0045] In some embodiments, the rigid support layer 112 plays a major supporting role for the entire display module 100 , and therefore needs to use a material with greater rigidity or greater elastic modulus. The elastic modulus of the rigid support layer 112 is greater than 150 Gpa. Furthermore, the elastic modulus of the rigid support layer 112 is 150 Gpa to 200 Gpa.

[0046] In some embodiments, the material of the rigid support layer 112 can be metal, such as stainless steel (SUS), titanium alloy, etc. The rigid support layer 112 also has the function of dissipating heat for the display panel 130, and metals such as stainless steel (SUS) and titanium alloy have good heat dissipation effect.

[0047] In some embodiments, the material of the rigid support layer 112 may also be a composite fiber board, such as a carbon fiber composite board, but not limited thereto. The composite fiber board has the characteristics of high strength, high modulus, good heat dissipation effect, and light weight, which is conducive to the thinness and heat dissipation of the display module 100.

[0048] In some embodiments, the thickness of the flexible supporting layer 111 ranges from 25 μm to 50 μm. The thickness of the flexible supporting layer 111 within this range can satisfy the supporting performance of the flexible supporting layer 111 without increasing the thickness of the display module 100. In the present application, the thickness of the flexible supporting layer 111 can be less than or equal to the thickness of the buffer layer 101 in the prior art. For example, the flexible supporting layer 111 and the buffer layer 101 in the prior art can be replaced with equal thickness, so the overall thickness of the module will not be increased.

[0049] In some embodiments, the thickness of the rigid support layer 112 ranges from 20 μm to 120 μm, and further the thickness of the rigid support layer 112 ranges from 80 μm to 120 μm. The thickness of the rigid support layer 112 of the present application is less than 120 μm, and there will be no orange-striped appearance phenomenon, which is reduced compared to the thickness of the metal support layer 102 in the prior art, while the thickness of the metal support layer 102 in the prior art is above 120 μm, and the orange-striped appearance phenomenon will appear when the thickness of the metal support layer 102 in the prior art is less than 120 μm. In the present application, when the thickness of the rigid support layer 112 is within this range, it can satisfy the requirement of having a good support effect on the entire display module 100, so that the overall performance of the display module 100 is better.

[0050] In some embodiments, see Figure 3 Since the scratch resistance of ultra-thin flexible glass is poor, in order to protect the flexible supporting layer 111, the present application sets the edge of the flexible supporting layer 111 inward relative to the edge of the rigid supporting layer 112, that is, each edge of the rigid supporting layer 112 extends out of the corresponding edges of the flexible supporting layer 111 to protect the flexible supporting layer 111.

[0051] In the present application, by adding a metal layer under the ultra-thin flexible glass, the scratch resistance of the metal material can be used to protect the ultra-thin flexible glass material, and the overall support performance of the support assembly 110 can also be supplemented. The ultra-thin flexible glass is retracted into the metal layer, and the metal layer can protect the edge of the ultra-thin flexible glass.

[0052] In some embodiments, see Figure 3The distance between the edge of the flexible support layer 111 and the edge of the rigid support layer 112 is a, and the range of a is 0.15mm to 0.30mm. When the inward distance of the rigid support layer 112 is within this range, the edge of the flexible support layer 111 can be effectively protected without increasing the overall size of the display module 100.

[0053] In some embodiments, see Figure 2 , the support assembly 110 further includes a first adhesive layer 113 and a second adhesive layer 114. The first adhesive layer 113 is disposed between the backplane layer 120 and the flexible support layer 111 to connect the backplane layer 120 and the flexible support layer 111. The second adhesive layer 114 is disposed between the flexible support layer 111 and the rigid support layer 112 to connect the flexible support layer 111 and the rigid support layer 112. The materials of the first adhesive layer 113 and the second adhesive layer 114 may be a pressure sensitive adhesive (PSA), such as a transparent pressure sensitive adhesive, but are not limited thereto.

[0054] In some embodiments, the first bonding layer 113 can also be used as a reflective layer to reduce the reflection phenomenon caused by the deformation of the lower material of the flexible support layer 111, so as to further optimize the appearance of the display module 100 and improve the display quality. The material of the first bonding layer 113 can also include reflective particles. The reflective particles can be black particles. For example, by adding nano-scale carbon black particles to the transparent pressure-sensitive adhesive, the transparent pressure-sensitive adhesive is formed into a black pressure-sensitive adhesive, wherein the nano-scale carbon black particles can absorb light, reduce the transmittance of the pressure-sensitive adhesive, and thus reduce the reflection phenomenon caused by the deformation of the lower material of the flexible support layer 111. By adding reflective particles to the first bonding layer 113, the first bonding layer 113 has both the function of bonding the upper and lower film layers and the function of anti-reflection, thereby avoiding the problem of increasing the overall thickness of the display module 100 due to the additional addition of an anti-reflection film layer.

[0055] In some embodiments, see Figure 2 and Figure 4 The display panel 130 is a foldable display panel, and the display panel 130 includes a bending area AA and non-bending areas NA located on opposite sides of the bending area AA. The rigid support layer 112 includes a first support portion 1121 corresponding to the bending area AA and a second support portion 1122 corresponding to the non-bending area NA, and the first support portion 1121 is provided with a stress release structure 1123. The stress release structure 1123 can be a patterned structure, such as a groove or a through hole, disposed on the first support portion 1121 to release the stress of the first support portion 1121 during the bending process, thereby improving the service life of the first support portion 1121, and thereby improving the service life of the entire display module 100.

[0056] In some embodiments, see Figure 2 , Figure 5 and Figure 6, the display module 100 also includes a shell, which is arranged on the side of the rigid support layer 112 away from the flexible support layer 111, and can be a whole surface covering the side surface of the rigid support layer 112 away from the flexible support layer 111; further, the display module 100 also includes a sealant 160, and the sealant 160 is arranged between the shell and the rigid support layer 112. The sealant 160 can be a foam tape or a spot glue, which is attached to the local area of ​​the side of the rigid support layer 112 away from the flexible support layer 111, and is used to bond the shell and the rigid support layer 112. In the present application, the area of ​​the flexible support layer 111 corresponding to the sealant 160 is located in the same plane as other areas of the flexible support layer 111, that is, the flexible support layer 111 is a flat surface and does not deform.

[0057] During the assembly process of the display module 100, due to the thinning of the rigid support layer 112, when the frame glue 160 is attached, the rigid support layer 112 is more easily deformed after being locally compressed. Figure 5 The local deformation of the metal support layer 102 caused by the sealant 160 will cause the second adhesive layer 114, the buffer layer 101 and other film layers above it to deform, and finally cause local concave and convex marks to appear on the front of the display module 100. The human eye can clearly see the traces caused by the deformation of the metal support layer 102 on the front of the display module 100 under ambient light, which affects the appearance of the display module 100. In this application, please refer to Figure 6 Although the rigid support layer 112 is thinned, it is easy to produce concave-convex deformation caused by the frame glue 160, but because the flexible support layer 111 has a higher hardness and a higher elastic modulus, the local deformation generated by the rigid support layer 112 is terminated when it is transmitted to the flexible support layer 111, and the flexible support layer 111 is not deformed. The film layer above the flexible support layer 111 is less affected, and the traces caused by the deformation of the rigid support layer 112 that can be seen by the human eye on the front of the display module 100 under ambient light are weakened. Therefore, the appearance impact caused by the thinning of the rigid support layer 112 can be improved.

[0058] In some embodiments, see Figure 2 The display module 100 further includes a polarizing layer 140, which is disposed on a side of the display panel 130 away from the backplane layer 120 to improve light extraction efficiency. An adhesive layer may also be included between the polarizing layer and the display panel 130 and the backplane layer 120 to bond the polarizing layer 140 and the display panel 130.

[0059] In some embodiments, see Figure 2The display module 100 further includes a cover plate 150, which is disposed on a side of the polarizing layer 140 away from the display panel 130 to protect the display module 100. An adhesive layer is further provided between the cover plate 150 and the polarizing layer 140 to bond the cover plate 150 and the polarizing layer 140. The material of the cover plate 150 may be an inorganic material, such as glass, or an organic material, such as PET or PI, but is not limited thereto.

[0060] In addition, in the present application, there is no need to set a buffer layer between the display panel 130 and the rigid support layer 112. Instead, the buffer layer affects the impact resistance of the display module 100. The present application sets a flexible support layer 111 with greater hardness between the display panel 130 and the rigid support layer 112, which can make the display module 100 have higher impact resistance, thereby improving the overall mechanical properties of the display module 100.

[0061] The present application also provides a display device, which includes the above-mentioned display module 100. The display device has all the beneficial effects of the above-mentioned display module 100, which will not be described in detail in the present application.

[0062] The display device may be a display product such as a mobile phone, a tablet, or a computer, but is not limited thereto.

[0063] In the display module and display device provided by the embodiments of the present application, the support component includes a flexible support layer and a rigid support layer, wherein the flexible support layer is located between the rigid support layer and the backplane layer. The position of the flexible support layer of the present application is equivalent to the buffer layer in the module support layer of the prior art. In the prior art, the buffer layer and the backplane layer are both made of PET or PI materials with equivalent elastic moduli, while the elastic modulus of the flexible support layer of the present application is greater than that of the backplane layer. The increase in the elastic modulus of the flexible support layer makes the film layer harder, which can improve the overall support performance and impact resistance of the support component to the outside world. After replacing the existing buffer layer with a flexible support layer with higher hardness, the thickness of the rigid support layer can be reduced accordingly, so that the thickness of the rigid support layer is reduced to less than 120μm, so as to further reduce the thickness of the display module. Therefore, the combination of the flexible support layer and the rigid support layer in the present application can reduce the thickness of the display module while avoiding problems such as poor orange-striped appearance on the front of the display module.
