Description

Technical Field

[0001] This invention relates to the field of display technology, and more particularly to a display module and display device. Background Technology

[0002] To enhance the lifespan of flexible display modules, related technologies employ a metal support layer to support the display panel. This support layer features perforated patterns in the bending areas of the display panel to reduce its elastic modulus, allowing the display panel to be rolled or folded according to specific designs. However, for large-size display modules, if the perforated patterns are formed using chemical etching, the support layer itself is easily bent and flexible. During the etching and bonding process, the patterned areas of the support layer are prone to damage and deformation, and gaps may not be able to be closed, resulting in a low overall yield and high cost. Summary of the Invention

[0003] This invention provides a display module and display device that can solve the technical problem that the patterned area of ​​the support layer in existing display modules is prone to folding and deformation, and that slits cannot be connected.

[0004] This invention provides a display module, comprising:

[0005] A display panel includes a bent area and two non-bent areas located on opposite sides of the bent area; and

[0006] A support assembly is disposed on the non-light-emitting side of the display panel. The support assembly includes a first support layer and a second support layer connected to each other. The orthographic projection of the first support layer on the display panel covers the two non-bending areas, and the orthographic projection of the second support layer on the display panel at least covers the bending area.

[0007] According to the display module provided by the present invention, the first support layer includes two separately disposed non-bending support portions and a gap region located between the two non-bending support portions;

[0008] The second support layer includes an integrated first main body and two first connecting parts located on opposite sides of the first main body. The first main body and the first connecting parts are located in the interval area, and the first connecting parts are detachably connected to the corresponding non-bending support parts.

[0009] According to the display module provided by the present invention, a first connector is provided on the side of the first connecting portion near the non-bending support portion, and a second connector is provided on the side of the non-bending support portion near the first connecting portion, wherein the first connector and the second connector engage with each other.

[0010] According to the display module provided by the present invention, the second support layer further includes an integrated second main body and two second connecting portions located on opposite sides of the second main body. The second main body is located on the side of the first main body away from the display panel, and the second connecting portions are located on the side of the first connecting portions away from the display panel.

[0011] The second connecting part has a stepped area on the side near the display panel, and at least part of the non-bending support part is disposed in the stepped area and is detachably connected to the second connecting part.

[0012] According to the display module provided by the present invention, the non-bending support portion is provided with a plurality of filling holes, and the second connecting portion is provided with a plurality of filling pillars corresponding to the plurality of filling holes on the side near the display panel, and the filling pillars are fitted into the corresponding filling holes.

[0013] According to the display module provided by the present invention, the bending area includes a main bending area and two transition bending areas located on opposite sides of the main bending area;

[0014] The second support layer includes a first sub-region and two second sub-regions arranged along a first direction. The two second sub-regions are located on opposite sides of the first sub-region. The first sub-region is directly opposite the main bending region, and the second sub-region is directly opposite the transition bending region.

[0015] In the bending area, the second support layer has a plurality of grooves spaced apart along the first direction on the side away from the display panel. In the second direction, the depth of the groove in the first sub-region is less than the depth of the groove in the second sub-region. The first direction intersects the extension direction of the bending axis of the display module, and the second direction is the thickness direction of the display module.

[0016] According to the display module provided by the present invention, the depth of the plurality of grooves located in the first sub-region gradually increases in the second direction along the first direction.

[0017] According to the display module provided by the present invention, the second support layer includes a third sub-region and a fourth sub-region arranged along the extension direction of the bending axis of the display module in the bending area, wherein the fourth sub-region is located on opposite sides of the third sub-region; wherein the fourth sub-region extends in a divergent manner from the edge of the third sub-region in a direction away from the third sub-region.

The present invention replaces the support layer made of a single sheet of metal material used in related technologies with a first support layer and a second support layer using different elastic moduli. Because the second support layer itself has a low elastic modulus and is easy to process, it does not require a hollow pattern, thus eliminating the complex processing technology of a single sheet of metal film, significantly reducing module production costs, and meeting the requirements of large-size screens.

[0037] The technical solutions of the embodiments of the present invention 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 the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0038] In the description of this invention, it should be understood that the terms "length," "width," "thickness," "upper," "lower," etc., indicating orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0039] In this invention, unless otherwise expressly specified and limited, the first feature "above" or "below" the second feature may include direct contact between the first and second features, or contact between the first and second features not in direct contact but through another feature between them.

[0040] In related technologies, a metal support layer is used to support the display panel. The support layer has perforated patterns in the bending areas of the display panel to reduce its elastic modulus, allowing the display panel to be rolled or folded according to specific designs. However, for large-size display modules, the perforated patterns are generally formed by chemical etching. Due to the flexible and easily bent nature of the support layer itself, the patterned areas of the support layer are prone to folding and deformation during the etching and bonding process, and the slits may not be able to be connected, resulting in a low overall yield and high cost.

[0041] Based on this, the present invention provides a display module and display device that can solve the technical problem that the patterned area of ​​the support layer in the existing display module is prone to bending and deformation, and that the slits cannot be connected.

[0042] The display module and display device provided by the present invention will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.

[0043] Please see Figure 1 and Figure 2 This invention provides a display module, including a display panel 1 and a support component 2. The display panel 1 includes a bending region 11 and two non-bending regions 12 located on opposite sides of the bending region 11. The support component 2 is disposed on the non-light-emitting side of the display panel 1. The support component 2 includes a first support layer 21 and a second support layer 22 connected to each other. The orthographic projection of the first support layer 21 onto the display panel 1 covers the two non-bending regions 12, and the orthographic projection of the second support layer 22 onto the display panel 1 at least covers the bending region 11. The elastic modulus of the second support layer 22 is less than that of the first support layer 21.

[0044] It is understood that the present invention replaces the support layer using a whole sheet of metal material in the related technology with a first support layer 21 and a second support layer 22 using different elastic moduli. Since the second support layer 22 itself has the characteristics of low elastic modulus and easy processing, it does not need to set a hollow pattern, which can save the complex processing process of the whole sheet of metal film material, greatly reduce the module production cost, and meet the requirements of large-size screen.

[0045] Specifically, the display module can be a foldable display module, and correspondingly, the display panel 1 can be a foldable display panel. In the flattened state, both the bending area 11 and the non-bending area 12 are flat and located on the same horizontal plane. In the folded state, the bending area 11 can be bent around the bending axis 11a of the bending area 11, so that the two non-bending areas 12 located on both sides of the bending area 11 are arranged opposite each other, thereby realizing the folding of the display module.

[0046] It should be noted that the embodiments of the present invention are illustrated by taking the display panel 1 as having one bent area 11 and two non-bent areas 12 as an example. However, it should be understood that the display panel 1 may also include two or more bent areas 11 and three or more non-bent areas 12, and the present invention is not limited thereto.

[0047] The display panel 1 can be an organic light-emitting diode (OLED) display panel, which includes an array substrate (not shown in the figure), an organic light-emitting layer (not shown in the figure), an encapsulation layer (not shown in the figure), and a touch layer (not shown in the figure) stacked sequentially. The array substrate may include a driving circuit, and the organic light-emitting layer may include multiple light-emitting elements. The driving circuit is electrically connected to the light-emitting elements to drive them to emit light.

[0048] It should be noted that this embodiment of the invention uses an organic light-emitting diode (OLED) display panel as an example for illustration, but the invention is not limited to this. In other embodiments, other types of display panels may also be used. Furthermore, this embodiment of the invention may also include other structures necessary to ensure the normal operation of the display panel 1, which will not be elaborated here.

[0049] In one embodiment, the material of the first support layer 21 includes metal, and optionally, it may include stainless steel film or Invar alloy. Of course, the present invention does not limit the range of materials of the first support layer 21, and can refer to all metal film materials.

[0050] In one embodiment, the material of the second support layer 22 includes plastic, optionally including polypropylene (PP) synthetic materials. Polypropylene is a polymer formed by the addition polymerization of propylene, and is a white, waxy material that is transparent and lightweight. It has excellent mechanical properties, including tensile strength, compressive strength, and hardness, outstanding rigidity, and resistance to bending fatigue. A movable hinge made of polypropylene can withstand 7 × 10⁻⁶ mm of bending fatigue. 7 It can withstand multiple folds and bends without damage. Similarly, this invention does not limit the scope of plastic materials used; any plastic material with excellent tensile strength, compressive strength, and resistance to flexural fatigue can be used in this invention.

[0051] It should be noted that in the existing technology, a full-surface metal film layer is used as the support layer, and a hollow pattern is set in the metal film layer corresponding to the bending area 11 of the display panel 1 to improve the bending ability of the metal film layer. For small-sized displays, the hollow pattern is usually formed by chemical etching, which is simple to produce and has high output efficiency. However, for large-sized displays, if the hollow pattern is still formed by chemical etching, it will cause defects in the pattern area of ​​the metal film layer, especially since the film material has been damaged and bent during the handling and transfer process. In addition, the deformation of the metal film material during the etching process may also cause the slits to be unable to be connected.

[0052] In this embodiment of the invention, the portion of the support layer corresponding to the non-bending area 12 of the display panel 1 (i.e., the first support layer 21) still uses a metal film material, while the portion of the support layer corresponding to the bending area 11 of the display panel 1 (i.e., the second support layer 22) is replaced with a plastic film material. Because plastic film material itself has low elastic modulus and is easy to process, it is easier to bend without the need for a perforated pattern. This eliminates the need for the complex processing of a full-surface metal film material, significantly reducing module production costs and meeting the requirements of large-size screens. Furthermore, since the price of plastic film material is lower than that of metal film material, eliminating the metal film layer in the bending area 11 further reduces module production costs.

[0053] Specifically, considering the dimensional stability, flatness, rigidity and surface hardness of metal materials, the plastic film material and the metal film material are joined by an integral injection molding process. That is, the first support layer 21 and the second support layer 22 are formed by integral injection molding.

[0054] It is understood that the side surface of the first support layer 21 near the display panel 1 and the side surface of the second support layer 22 near the display panel 1 are located on the same plane, so that the side surface of the support component 2 near the display panel 1 is flat, thereby providing a flat support surface for the display panel 1.

[0055] In one embodiment, such as Figure 2 As shown, the orthographic projection of the first support layer 21 on the display panel 1 covers the entire non-bending area 12, and the orthographic projection of the second support layer 22 on the display panel 1 covers the entire bending area 11. That is, there is no overlapping area between the orthographic projections of the first support layer 21 and the second support layer 22 on the display panel 1.

[0056] In another embodiment, please refer to Figure 3 The orthographic projection of the first support layer 21 on the display panel 1 covers a portion of the non-bending area 12, and the orthographic projection of the second support layer 22 on the display panel 1 covers the entire bending area 11 and a portion of the non-bending area 12. That is, the orthographic projections of the first support layer 21 and the second support layer 22 on the display panel 1 have an overlapping area, and the first support layer 21 and the second support layer 22 are joined in the overlapping area.

[0057] For details, please refer to Figures 3-4 The first support layer 21 includes two separately disposed non-bending support portions 211, with a gap region 212 between the two non-bending support portions 211; the second support layer 22 includes an integrated first main body portion 221 and two first connecting portions 222 located on opposite sides of the first main body portion 221, the first main body portion 221 and the first connecting portions 222 are located within the gap region 212, and the first connecting portions 222 are detachably connected to the corresponding non-bending support portions 211, thus enabling the joining of the first support layer 21 and the second support layer 22.

[0058] In this embodiment, the first connecting portion 222, the first main body portion 221, and the non-bending support portion 211 are located on the same plane.

[0059] Furthermore, such as Figure 4 and Figures 5A-5B As shown, a first connector 2221 is provided on the side of the first connecting portion 222 near the non-bending support portion 211, and a second connector 2111 is provided on the side of the non-bending support portion 211 near the first connecting portion 222. The first connector 2221 and the second connector 2111 engage with each other to achieve a fixed connection between the first connecting portion 222 and the non-bending support portion 211, thereby achieving a fixed connection between the first support layer 21 and the second support layer 22.

[0060] Specifically, such as Figure 5A As shown, the first connector 2221 includes a plurality of first protrusions 2221a and a first groove 2221b located between two adjacent first protrusions 2221a. The second connector 2111 includes a plurality of second protrusions 2111a and a second groove 2111b located between two adjacent second protrusions 2111a. The first protrusions 2221a and the second grooves 2111b are correspondingly arranged and have the same shape. The second protrusions 2111a and the first grooves 2221b are correspondingly arranged and have the same shape, so that the first protrusions 2221a are fitted into the second grooves 2111b and the second protrusions 2111a are fitted into the first grooves 2221b. In this way, by designing the structural boundaries of the first support layer 21 and the second support layer 22 as teeth, the engagement of the first support layer 21 and the second support layer 22 is achieved, while increasing the metal cross-sectional interlocking force, preventing the edge of the first support layer 21 from lifting, and making it more convenient to assemble the two layers together, and facilitating disassembly and maintenance.

[0061] Specifically, the arrangement direction of the first protrusion 2221a and the first groove 2221b, as well as the arrangement direction of the second protrusion 2111a and the second groove 2111b, are all parallel to the extension direction of the bending axis 11a.

[0062] In embodiments of the present invention, such as Figure 5B As shown, taking the second connector 2111 as an example, the distance between the second protruding tooth 2111a and the outer boundary of the non-bending support portion 211 is H, the protruding width of the second protruding tooth 2111a is H1, and the spacing between two adjacent second protruding teeth 2111a is H2. Therefore, H = 2H1, H1 = H2. The value of H2 ranges from 10 mm to 20 mm. Optionally, the value of H2 can be one of 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, and 20 mm.

[0063] Of course, in other embodiments, the first connector 2221 and the second connector 2111 may also be a wave-shaped structure or other types of structures, as long as they can be spliced ​​and connected, they are all within the protection scope of this invention.

[0064] Furthermore, in one embodiment, please refer to Figure 6To increase the bonding capability of the first support layer 21 and the second support layer 22, and to increase the bending capability of the second support layer 22, the second support layer 22 further includes an integrated second main body 223 and two second connecting portions 224 located on opposite sides of the second main body 223. The second main body 223 is located on the side of the first main body 221 away from the display panel 1, and the second connecting portions 224 are located on the side of the first connecting portions 222 away from the display panel 1. A stepped area 2241 is provided on the side of the second connecting portion 224 near the display panel 1. At least a portion of the non-bending support portion 211 is disposed in the stepped area 2241 and is detachably connected to the second connecting portion 224. That is, in this embodiment of the invention, the first main body 221 and the second main body 223 are used to achieve bending, and the first connecting portion 222 and the second connecting portion 224 are used to connect with the first support layer 21.

[0065] It should be noted that the stepped area 2241 refers to the area on the side surface of the second connecting part 224 near the display panel 1 that is not covered by the first connecting part 222.

[0066] For details, please refer to Figure 7 The non-bending support portion 211 is provided with a plurality of filling holes 2112. The second connecting portion 224 is provided with a plurality of filling posts 2242 corresponding to the plurality of filling holes 2112 on the side near the display panel 1. The filling posts 2242 are fitted into the corresponding filling holes 2112. In this way, the joint area between the first support layer 21 and the second support layer 22 is increased, so that the first support layer 21 and the second support portion can be more firmly joined together, and better interlocking can be achieved in the horizontal and vertical directions, thereby improving the joint strength.

[0067] Specifically, the length direction of the filling hole 2112 is parallel to the extension direction of the bending axis 11a, and the width direction of the filling hole 2112 is perpendicular to the extension direction of the bending axis 11a. Multiple filling holes 2112 are arranged in multiple rows and columns, wherein the row arrangement direction of the filling holes 2112 is parallel to the extension direction of the bending axis 11a, and the column arrangement direction of the filling holes 2112 is perpendicular to the extension direction of the bending axis 11a. Multiple filling holes 2112 in adjacent columns are staggered. This embodiment of the invention does not impose specific limitations on the number of filling holes 2112 in each row or column; the number should be determined based on the dimensions of the non-bending support portion 211 and the second connecting portion 224.

[0068] In the embodiments of the present invention, please refer to Figure 8Taking the second connector 2111 as an example, the distance between two adjacent filling holes 2112 in the same column is W, the length of the filling hole 2112 is W1, the minimum distance between the edge of the filling hole 2112 and the edge of the non-bending support 211 is W2, the width of the filling hole 2112 is S1, and the distance between two filling holes 2112 in two adjacent columns is S. Then, W2 = W, W1 = 2 * W, and S = 2 * S1. Wherein, the value of W1 ranges from 2 mm to 6 mm, and the value of S1 ranges from 1 mm to 3 mm. Optionally, the value of W1 includes one of 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, 5.5 mm, and 6 mm, and the value of S1 ranges one of 1 mm, 1.5 mm, 2 mm, 2.5 mm, and 3 mm.

[0069] Optionally, the filling hole 2112 can be formed by laser cutting or die punching, but other processing methods can also be used, and the present invention does not limit this.

[0070] In other embodiments, the first connecting portion 222 and the corresponding non-bending support portion 211, and the second connecting portion 224 and the corresponding non-bending support portion 211, can also be fixedly connected by means of adhesive, riveting or welding.

[0071] In one embodiment, please refer to Figure 9 When the display panel 1 is bent, the bending area 11 takes the shape of a teardrop. Specifically, the bending area 11 includes a main bending area 111 and transition bending areas 112 located on opposite sides of the main bending area 111. The main bending area 111 is located between the two transition bending areas 112. The main bending area 111 is the area where bending mainly occurs, and the transition bending areas 112 are areas that provide a smooth or gradual transition, preventing the display panel 1 from breaking or developing creases.

[0072] For the corresponding information, please refer to [link / reference]. Figure 10The second support layer 22 includes a first sub-region 225 and two second sub-regions 226 arranged along the first direction X. The two second sub-regions 226 are located on opposite sides of the first sub-region 225. The first sub-region 225 is directly opposite the main bending region 111, and the second sub-regions 226 are directly opposite the transition bending region 112. Furthermore, in this embodiment of the invention, to further reduce the overall elastic modulus of the second support layer 22, and because the plastic material will accumulate and be compressed during bending, making bending impossible, a plurality of grooves 229 spaced apart along the first direction X are provided on the side of the second support layer 22 away from the display panel 1 in the bending region 11. The use of grooves 229 helps to solve the problem of plastic material accumulation and compression.

[0073] Specifically, in the second direction Y, the depth of the groove 229 located in the first sub-region 225 is less than the depth of the groove 229 located in the second sub-region 226. The first direction X intersects the extension direction of the bending axis 11a of the display module, and the second direction Y is the thickness direction of the display module.

[0074] Furthermore, the depth of the plurality of grooves 229 located in the first sub-region 225 in the second direction Y gradually increases along the first direction X. Thus, the first sub-region 225 adopts a gradient design, which enables the elastic modulus of the first sub-region 225 and the second sub-region 226 to gradually transition, avoiding the situation where the bending shape changes abruptly due to abrupt changes in the elastic modulus.

[0075] Specifically, the thickness of the first support layer 21 in the bending area 11 is T, that is, the overall thickness of the first main body 221 and the second main body 223 in the bending area 11 is T. Then, the depth of the groove 229 located in the second sub-area 226 in the second direction Y is T / 3, and the depth of the groove 229 located in the first sub-area 225 in the second direction is T / 4 and T / 5.

[0076] In one embodiment, considering that the display module further includes flexible circuitry disposed on opposite sides of the display panel 1, the radial stress of the support component 2 in the bending area 11 increases sharply. This affects the bonding stability of the flexible circuitry. Therefore, in this embodiment of the invention, please refer to... Figure 11 and Figure 12The second support layer 22 includes a third sub-region 227 and a fourth sub-region 228 arranged along the extension direction of the bending axis 11a of the display module in the bending area 11. The fourth sub-region 228 is located on opposite sides of the third sub-region 227. The fourth sub-region 228 extends outward from the edge of the third sub-region 227 in a divergent manner. In this way, the edge region of the second support layer 22 is designed as a triangular region, which is beneficial to improve the distribution and gradual change of stress.

[0077] Furthermore, such as Figure 12 As shown, the second support layer 22 is provided with a plurality of diamond-shaped holes 2281 in the fourth sub-region 228, which can further improve the distribution and gradual change of stress.

[0078] In embodiments of the present invention, such as Figure 2 and Figure 6 As shown, the display module also includes a protective cover plate 3, which is disposed on the side of the display panel 1 away from the support component 2, for protecting the display panel 1. Optionally, the protective cover plate 3 can be a glass cover plate.

The display device provided in the embodiments of the present invention can be at least one of a smartphone, tablet computer, mobile phone, video phone, e-book reader, laptop PC, netbook computer, workstation, server, personal digital assistant, portable multimedia player, MP3 player, mobile medical device, camera, game console, digital camera, car navigation system, electronic billboard, ATM, smart bracelet, smartwatch, virtual reality (VR) device, or wearable device. The display module has been described in detail in the above embodiments; therefore, further details about the display module are not provided in the embodiments of the present invention.

[0080] Beneficial Effects: In the display module and display device provided by this invention, the display module includes a display panel and a support component disposed on the light-emitting side of the display panel. The support component includes a first support layer and a second support layer connected to each other. The orthographic projection of the first support layer on the display panel covers two non-bending areas, and the orthographic projection of the second support layer on the display panel covers at least the bending area. The elastic modulus of the second support layer is less than that of the first support layer. This invention replaces the support layer made of a single sheet of metal material used in related technologies with a first support layer and a second support layer using different elastic moduli. Because the second support layer itself has low elastic modulus and is easy to process, it does not require a hollow pattern, thus eliminating the complex processing technology of a whole sheet of metal film, significantly reducing the module production cost, and meeting the requirements of large-size screens.
