Abstract

The present disclosure relates to a display module, a screen module and an electronic device. The display module comprises: a display panel comprising a display area and a bending area; a polarizing layer, which is arranged in the display area in a laminated manner and has a first edge side close to the bending area; and a first optically transparent adhesive layer, which is arranged in the bending area in a laminated manner with the polarizing layer and covers the bending area. The first optically transparent adhesive layer has a second edge side close to the polarizing layer. The second edge side is adjacent to the first edge side and has no overlap in the orthogonal projection in the thickness direction of the display panel. In this way, the stress concentration point is avoided at the edge position of the first optically transparent adhesive layer and the polarizing layer.

Description

Technical Field

[0001] This disclosure relates to the field of electronic equipment technology, and in particular to a display module, a screen module, and an electronic device. Background Technology

[0002] With the development of science and technology, users have increasingly higher requirements for electronic devices. Narrow-bezel display modules have attracted widespread attention due to their larger screen-to-body ratio. Related technologies often involve bending or folding a portion of the display panel structure onto the backlight side of the display module to reduce its space occupation and achieve the narrow-bezel effect. Simultaneously, protective adhesive is applied to the bent sections of the display panel to protect against static electricity and reduce bending stress.

[0003] However, because the protective adhesive forms stress concentration points when it comes into contact with the edge of the polarizer, electronic devices may experience screen distortion or touch malfunction when dropped. Utility Model Content

[0006] In some embodiments, the display module further includes a second optically transparent adhesive layer; the second optically transparent adhesive layer is bonded to the side of the polarizing layer away from the display area, and the orthographic projection of the second optically transparent adhesive layer on the display panel is located in the display area; the first optically transparent adhesive layer and the second optically transparent adhesive layer have the same material.

[0007] In some embodiments, the first optically transparent adhesive layer and the second optically transparent adhesive layer are segments of the same optically transparent adhesive, and the orthographic projections of the segments in the thickness direction of the display panel do not overlap.

[0008] In some embodiments, the second optically transparent adhesive layer has a third edge side near the bending region, the third edge side being adjacent to the first edge side.

By making the second edge side of the first optically transparent adhesive layer near the polarizing layer adjacent to the first edge side of the polarizing layer near the bending area, the orthographic projections of the second edge side and the first edge side in the thickness direction of the display panel do not overlap, thereby avoiding the formation of stress concentration points at the edges of the first optically transparent adhesive layer and the polarizing layer. Through the above structural setting, the peeling of the internal film layer and the breakage of the circuit caused by stress concentration during the drop of electronic devices are avoided, which would lead to screen distortion or touch failure.

[0031] Some embodiments of this disclosure will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. Various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will become apparent upon understanding this disclosure. For example, the order of operations described herein is merely illustrative and is not limited to those orders set forth herein, but can be changed as will become apparent upon understanding this disclosure, except for operations that must be performed in a particular order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0032] The embodiments described in the following examples of this disclosure are not representative of all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0033] In related technologies, electronic devices typically incorporate a portion of the display panel structure within the display module onto the backlight side of the module through bending or other methods. This reduces the space occupied by this portion of the structure, achieving a narrow bezel effect. The technology involves applying a protective adhesive, such as bending protection layer (BPL) glue, to the bent portion of the display panel to protect against static electricity and reduce bending stress. Figure 1 and Figure 2 As shown, the current processing technology scheme for the display module is as follows:

[0034] After the polarizer 1 is bonded to the display panel 10, BPL adhesive 2 is applied. Adhesive 2 is applied along the edge of the polarizer 1. Due to the siphon effect, the adhesive 2 at the position of the polarizer 1 protrudes above the polarizer 1, resulting in uneven overall thickness. Ultraviolet (UV) lamps cure the BPL adhesive 2, preventing it from flowing. Optical transparent adhesive 3 is then bonded to the polarizer 1. First, the protective film of the polarizer 1 is removed. The protective film carries away the cured BPL adhesive 2, causing the cured BPL adhesive 2 at the edge of the polarizer 1 to further increase. After the glass cover of the screen module is bonded, the cured BPL adhesive 2 at the corresponding edge of the polarizer 1 will form stress concentration points. Due to the existence of these stress concentration points, when the electronic device is dropped, the internal film layer of the display panel at the corresponding location may peel off and the circuit may break, leading to screen distortion or touch malfunction.

[0035] To prevent screen distortion or touch malfunction caused by stress concentration during electronic device drops, embodiments of this disclosure provide a display module.

[0036] In one embodiment of this disclosure, the display module includes an optically transparent adhesive layer for covering the bending area 12 of the display panel 10. For ease of description, the optically transparent adhesive layer covering the bending area 12 of the display panel 10 will be referred to as the first optically transparent adhesive layer 30. A polarizing layer 20 is stacked on the display area 11 of the display panel 10. The polarizing layer 20 has a first edge side 21 near the bending area 12. The first optically transparent adhesive layer 30 is disposed in the same layer as the polarizing layer 20. The first optically transparent adhesive layer 30 is adhered to the bending area 12 to cover the bending area 12. The first optically transparent adhesive layer 30 has a second edge side 31 near the polarizing layer 20. The second edge side 31 is adjacent to the first edge side 21.

[0037] Furthermore, in this embodiment, the orthographic projections of the second edge side and the first edge side in the thickness direction of the display panel do not overlap. This avoids stress concentration points forming at the edges of the first optically transparent adhesive layer 30 and the polarizing layer 20. This structural design also prevents the peeling of the internal film layer and circuit breakage of the display panel 10 due to stress concentration during a drop of the electronic device, thus avoiding screen distortion or touch malfunction. Additionally, when peeling off the protective film of the polarizing layer 20, the first optically transparent adhesive layer 30 is prevented from being further lifted up, thus avoiding stress concentration points forming on the protruding portion. This structural design further prevents the peeling of the internal film layer and circuit breakage of the display panel 10 due to stress concentration during a drop of the electronic device, thus avoiding screen distortion or touch malfunction.

[0038] The display module provided in this disclosure provides electrostatic protection and reduces bending stress on the display panel 10 in the bending region 12 by providing a first optically transparent adhesive layer 30, which is on the same layer as the polarizing layer 20. This is achieved by placing a second edge 31 of the first optically transparent adhesive layer 30 near the polarizing layer 20 adjacent to a first edge 21 of the polarizing layer 20 near the bending region 12. The orthographic projections of the second edge 31 and the first edge 21 in the thickness direction of the display panel 10 do not overlap. This avoids stress concentration points forming at the edges of the first optically transparent adhesive layer 30 and the polarizing layer 20. This structural arrangement further prevents the internal film peeling and circuit breakage caused by stress concentration during electronic device drops, thus avoiding screen distortion or touch malfunction.

[0039] Figure 3 This is a schematic diagram of a display module in an unbent state, according to some embodiments of the present disclosure. Figure 4 This is a schematic diagram illustrating another display module in an unbent state, according to some embodiments of the present disclosure. (Refer to...) Figure 3-4 As shown, the display module includes a display panel 10, a polarizing layer 20, and a first optically transparent adhesive layer 30.

[0040] The display panel 10 includes a display area 11 and a bending area 12. A polarizing layer 20 is stacked on the display area 11 and has a first edge side 21 near the bending area 12. A first optically transparent adhesive layer 30 is disposed on the same layer as the polarizing layer 20 and is bonded to the bending area 12 to cover the bending area 12. The first optically transparent adhesive layer 30 has a second edge side 31 near the polarizing layer 20. The second edge side 31 is adjacent to the first edge side 21 and their orthographic projections in the thickness direction of the display panel 10 do not overlap.

[0041] The display panel 10 is one of the most important components in the display module, and it typically includes multiple layers of film (not shown in the figure) stacked together. The embodiments of this disclosure do not limit the internal film structure of the display panel 10. Exemplarily, the display panel 10 includes an array layer, a light-emitting layer, and an encapsulation layer stacked together.

[0042] It should be noted that during the manufacturing process of the display module, a portion of the structure in the display panel 10, namely the bending area 12, is usually placed on the backlight side of the display module by bending or other means, thereby reducing the space occupied by this part of the structure in the display module and achieving a narrow bezel effect.

[0043] The first optically clear adhesive layer 30 has a uniform thickness. The first optically clear adhesive layer 30 can be made of optically clear adhesive (OCA), which has low flowability and good softness and extensibility. Other types of optically clear adhesives can also be used for the first optically clear adhesive layer 30, and this disclosure does not limit this.

[0044] In this disclosure, by providing a first optically transparent adhesive layer 30, which is co-layered with the polarizing layer 20, in the bending region 12 of the display panel 10, electrostatic protection and bending stress reduction are achieved for the display panel 10 in the bending region 12. The second edge side 31 of the first optically transparent adhesive layer 30, near the polarizing layer 20, is adjacent to the first edge side 21 of the polarizing layer 20, near the bending region 12. The orthographic projections of the second edge side 31 and the first edge side 21 in the thickness direction of the display panel 10 do not overlap. This avoids stress concentration points forming at the edges of the first optically transparent adhesive layer 30 and the polarizing layer 20. This structural arrangement further prevents the peeling of the internal film layer and circuit breakage of the display panel 10 due to stress concentration during electronic device drops, thus avoiding screen distortion or touch malfunction.

[0045] In some embodiments, such as Figure 3 and Figure 4 As shown, the display module also includes a second optically transparent adhesive layer 40. The second optically transparent adhesive layer 40 is bonded to the side of the polarizing layer 20 away from the display area 11. The orthographic projection of the second optically transparent adhesive layer 40 on the display panel 10 is located in the display area 11. The first optically transparent adhesive layer 30 and the second optically transparent adhesive layer 40 have the same material.

[0046] The second optically transparent adhesive layer 40 can be a single layer or multiple layers, with the multiple layers of the second optically transparent adhesive layer 40 stacked together in the thickness direction of the display panel 10. The second optically transparent adhesive layer 40 can be optically transparent adhesive, i.e., OCA adhesive, or other types of optically transparent adhesive; this embodiment does not limit the choice.

[0047] In this embodiment of the disclosure, by using a first optically transparent adhesive layer 30 and a second optically transparent adhesive layer 40 of the same material, the main function is to attach the first optically transparent adhesive layer 30 and the second optically transparent adhesive layer 40 of the same material to the bending area 12 and the display area 11 of the display panel 10 respectively during the processing of the display module. There is no need to change different materials during the processing, which helps to save process flow and facilitates processing.

[0048] In some embodiments, such as Figure 3 As shown, the first optically transparent adhesive layer 30 and the second optically transparent adhesive layer 40 are segments of the same optically transparent adhesive, and the orthographic projections of the segments in the thickness direction of the display panel 10 do not overlap.

[0049] In this embodiment, due to the presence of the polarizing layer 20, there is a height difference between the first optically transparent adhesive layer 30 and the second optically transparent adhesive layer 40 in the thickness direction of the display panel 10. By setting the first optically transparent adhesive layer 30 and the second optically transparent adhesive layer 40 as segments of the same optically transparent adhesive, and bonding them segment by segment to the display panel 10, the operation is simpler. In addition, since the orthographic projections of the segments in the thickness direction of the display panel 10 do not overlap, the thickness of the display module is reduced, which is beneficial to the thinner and lighter design of electronic devices.

[0050] In some embodiments, such as Figure 3 As shown, the second optically transparent adhesive layer 40 has a third edge side 41 near the bending region 12, and the third edge side 41 is adjacent to the first edge side 21.

[0051] In this embodiment, the third edge side 41 is adjacent to the first edge side 21. The purpose of this arrangement is to protect the display area 11 and the bending area 12 from static electricity and reduce bending stress without causing stress concentration. This avoids the situation where stress concentration during the drop of electronic devices causes the internal film layer of the display panel 10 to peel off and the circuit to break, resulting in screen distortion or touch failure.

[0052] In some embodiments, the thickness of the first optically transparent adhesive layer 30 is less than or equal to a preset thickness, which is the sum of the thickness of the polarizing layer 20 and the thickness of the second optically transparent adhesive layer 40.

[0053] The preset film thickness is determined according to the design requirements in the actual production process, and this embodiment does not limit it.

[0054] In one scenario, the thickness of the first optically transparent adhesive layer 30 is less than the sum of the thicknesses of the polarizing layer 20 and the second optically transparent adhesive layer 40. By placing the first optically transparent adhesive layer 30 in the bending area 12 of the display panel 10 and the second optically transparent adhesive layer 40 in the display area 11 of the display panel 10, electrostatic protection and reduced bending stress are achieved for the display panel 10. Simultaneously, stress concentration points are avoided at the edges of the BPL adhesive and the polarizing layer 20 due to a siphon effect. This structural arrangement further prevents the internal film peeling and circuit breakage of the display panel 10 caused by stress concentration during electronic device drops, thus avoiding screen distortion or touch malfunction.

[0055] In another scenario, the thickness of the first optically transparent adhesive layer 30 is equal to the sum of the thicknesses of the polarizing layer 20 and the second optically transparent adhesive layer 40. By placing the first optically transparent adhesive layer 30 in the bending area 12 of the display panel 10 and the second optically transparent adhesive layer 40 in the display area 11 of the display panel 10, electrostatic protection and stress reduction of the display panel 10 are achieved. Simultaneously, stress concentration points are avoided at the edges of the BPL adhesive and the polarizing layer 20 due to a siphon effect. This structural arrangement further prevents the internal film peeling and circuit breakage of the display panel 10 caused by stress concentration during electronic device drops, thus avoiding screen distortion or touch malfunction.

[0056] In some embodiments, such as Figure 3 As shown, the third edge side 41 and the second edge side 31 are flush with each other in the direction facing the first edge side 21.

[0057] In this embodiment, by aligning the third edge side 41 and the second edge side 31 in the direction facing the first edge side 21, stress concentration points are avoided at the edges of the first optically transparent adhesive layer 30 and the polarizing layer 20. This structural arrangement further prevents stress concentration during drops from causing film peeling and circuit breakage within the display panel 10, which could lead to screen distortion or touch malfunction.

[0058] In some embodiments, such as Figure 4 As shown, the first optically transparent adhesive layer 30 and the second optically transparent adhesive layer 40 are integrally formed using the same optically transparent adhesive.

[0059] In this embodiment, by making the first optically transparent adhesive layer 30 and the second optically transparent adhesive layer 40 an integral structure of the same optically transparent adhesive, the second optically transparent adhesive layer 40 and the first optically transparent adhesive layer 30 can be bonded together at different stages of the same process during the manufacturing of the display module. For example, the second optically transparent adhesive layer 40 of the display area 11 can be bonded using a roller process. Then, the first optically transparent adhesive layer 30 of the bending area 12 is bonded using a roller process. After bonding, the first optically transparent adhesive layer 30 is adjacent to the first edge side 21 of the polarizing layer 20 through excess adhesive and covers the bending area 12. This avoids stress concentration points formed at the edge positions of the first optically transparent adhesive layer 30 and the polarizing layer 20 due to the siphon effect.

[0060] Based on the same concept, this disclosure also provides a screen module, which includes a display module as described in any of the above embodiments. Accordingly, the advantages of the above display modules are also present in the screen module, and will not be repeated here.

[0061] In some embodiments, such as Figure 3 and Figure 4 As shown, the display module includes a second optically transparent adhesive layer 40, and the screen module also includes a cover plate 50. The cover plate 50 is stacked on the side of the second optically transparent adhesive layer 40 away from the display panel 10, and the cover plate 50 covers the display area 11 and the bending area 12 in the orthographic projection of the display panel 10.

[0062] The cover plate 50 can be a glass cover plate or a cover plate of other transparent materials, and this embodiment does not limit it.

[0063] In this embodiment, after the polarizing layer 20 in the display module is bonded, there is no need to apply BPL adhesive. After the screen module is bonded to the cover plate 50, no stress concentration point will be formed at the first edge side 21 of the corresponding polarizing layer 20. Through the above structural setting, the peeling of the internal film layer and the breakage of the circuit caused by stress concentration during the drop of the electronic device are avoided, which would lead to screen distortion or touch failure.

[0064] Based on the same concept, embodiments of this disclosure also provide an electronic device, such as... Figure 5 As shown, the electronic device 100 includes a display module or a screen module as described in any of the above embodiments. Accordingly, the electronic device including such a display module or screen module also possesses the same advantages, which will not be elaborated further here.

[0065] In this disclosure, the electronic device 100 can be referred to as a terminal device, user equipment (UE), mobile station (MS), mobile terminal (MT), etc., and is a device that provides voice and / or data connectivity to a user. The electronic device can be: a smartphone (Mobile Phone), a pocket personal computer (PPC), a handheld computer, a personal digital assistant (PDA), a laptop computer, a tablet computer, a wearable device, or an in-vehicle device, etc.

[0066] Regarding the apparatus in the above embodiments, the specific manner in which each module performs its operation has been described in detail in the embodiments of the relevant display modules, and will not be elaborated here.

[0067] In the above detailed description, reference has been made to the accompanying drawings, which illustrate specific aspects of this disclosure by way of illustration. In this regard, terms indicating direction or positional relationship, such as “center,” “longitudinal,” “lateral,” “length,” “width,” “thickness,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” “outer,” “clockwise,” “counterclockwise,” “axial,” “radial,” and “circumferential,” are used with reference to the orientation of the described figures. Since components of the described device can be positioned in multiple different orientations, directional terms are used for illustrative purposes and not for limitation. It should be understood that other aspects can be utilized and structural or logical changes can be made without departing from the concept of this disclosure. Therefore, the following detailed description should not be considered limiting.

[0068] It should be understood that, unless otherwise specifically indicated, features of various embodiments of this disclosure described herein can be combined with each other. As used herein, the term "and / or" includes any of the associated listed items and any combination of any two or more; it should be understood that, unless otherwise expressly specified and limited, the terms "joining," "attaching," "mounting," "connecting," "linking," "fixing," etc., used in the embodiments of this disclosure should be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral part; as a mechanical connection, an electrical connection, or a communicative connection; as a direct connection or an indirect connection through an intermediate medium; as a connection within two elements or an interaction between two elements, unless otherwise expressly limited. Those skilled in the art will understand the specific meaning of the above terms herein according to the specific circumstances.

[0069] Furthermore, the term "above" as used herein with respect to components, elements, or material layers formed or located "above" a surface may be used to indicate that the component, element, or material layer is "indirectly" positioned (e.g., placed, formed, deposited, etc.) on the surface such that one or more additional components, elements, or layers are arranged between the surface and the component, element, or material layer. However, the term "above" as used with respect to components, elements, or material layers formed or located "above" a surface may also optionally have a specific meaning: that the component, element, or material layer is "directly" positioned (e.g., placed, formed, deposited, etc.) on the surface, for example, in direct contact with the surface.

[0070] It should be understood that spatial relative terms, such as “above,” “upper,” “below,” and “lower,” are used herein to describe the relationship between one element and another shown in the figures. In addition to the orientation depicted in the figures, these spatial relative terms are also intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as “above” or “upper” relative to another element would be “below” or “lower” relative to that other element. Thus, depending on the spatial orientation of the device, the term “above” encompasses both above and below orientations. Devices may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used herein should be interpreted accordingly.

[0071] Although terms such as “first,” “second,” and “third” may be used herein to describe various components, parts, regions, layers, or sections, these components, parts, regions, layers, or sections are not limited to these terms. Rather, these terms are used only to distinguish one component, part, region, layer, or section from another. Therefore, without departing from the teachings of the examples described herein, a first component, part, region, layer, or section mentioned in the examples may also be referred to as a second component, part, region, layer, or section. Furthermore, the terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as “first” or “second” may explicitly or implicitly include at least one of that feature.

[0072] It is further understood that the terms "first," "second," etc., are used to describe various types of information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another, and do not indicate a specific order or degree of importance. In fact, the expressions "first," "second," etc., are completely interchangeable. For example, without departing from the scope of this disclosure, first information can also be referred to as second information, and similarly, second information can also be referred to as first information.

[0073] In this description, "multiple" means at least two, referring to two or more, such as two, three, etc., unless otherwise explicitly specified. Other quantifiers are similar. The singular forms "a," "the," and "the" are also intended to include the plural forms unless the context clearly indicates otherwise. Furthermore, unless otherwise specified or clearly indicated from the context, the articles "a" and "an" as used in this application and the appended claims are generally understood to mean "one or more."

[0074] It should be understood that, unless otherwise specifically indicated, features of various embodiments of this disclosure described herein can be combined with each other. As used herein, the term "and / or" includes any one of the related listed items and any combination of two or more; "and / or" describes the association relationship between related objects, indicating that three relationships may exist, for example, A and / or B can represent: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. Similarly, "at least one of..." includes any one of the related listed items and any combination of two or more.

[0075] It is further understood that the terms "first," "second," etc., are used to describe various types of information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another, and do not indicate a specific order or degree of importance. In fact, the expressions "first," "second," etc., are completely interchangeable. For example, without departing from the scope of this disclosure, first information can also be referred to as second information, and similarly, second information can also be referred to as first information.

[0076] Furthermore, the term "exemplary" is used herein to indicate that it serves as an example, instance, or illustration. Any aspect or design described herein as "exemplary" is not necessarily to be construed as advantageous compared to other aspects or designs. Rather, the use of the term "exemplary" is intended to present concepts in a concrete manner. As used herein, the term "or" is intended to indicate an inclusive "or" rather than an exclusive "or." That is, unless otherwise specified or clear from the context, "X applies A or B" is intended to indicate any of the natural inclusive permutations. That is, if X applies A; X applies B; or X applies both A and B, then applying A or B satisfies the condition under any of the foregoing instances.

[0077] Similarly, although this disclosure has been shown and described with respect to one or more implementations, equivalent variations and modifications will occur to those skilled in the art upon reading and understanding the specification and drawings. This disclosure includes all such modifications and variations and is limited only by the scope of the claims. In particular, with respect to the various functions performed by the components described above (e.g., elements, resources, etc.), unless otherwise indicated, the terminology used to describe such components is intended to correspond to any component (functionally equivalent) that performs the specific function of the described component, even if it is not structurally equivalent to the disclosed structure. Furthermore, although specific features of this disclosure may have been disclosed with respect to only one of several implementations, such features may be combined with one or more other features of other implementations, as may be desired and advantageous to any given or particular application. Moreover, with regard to the terms “comprising,” “owning,” “having,” “having,” or variations thereof as used in this disclosure, such terms are intended to be inclusive in a manner similar to the term “including.”

[0078] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the utility models disclosed herein. This disclosure is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.

[0079] It should be understood that this disclosure is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope.
