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] Flexible display modules have been widely used in large-size products. In related technologies, the display module and heat dissipation film of large-size flexible display products are assembled by bonding with adhesive tape. How to reduce the overall thickness of the device has always been a demand from customers. Summary of the Invention

[0003] This disclosure provides a display module and display device that can reduce the overall thickness and simplify assembly processes.

[0004] The technical solutions provided in this disclosure are as follows:

[0005] In a first aspect, embodiments of this disclosure provide a display module, including:

[0006] Display panel;

[0007] The adhesive layer that is adhered to the backlight side of the display panel; and

[0008] A flexible support layer is attached to the side of the adhesive layer opposite to the display panel. The flexible support layer has a slotted area, which is configured such that an adhesive layer is adhered to its interior, and / or the interior of the slotted area can be filled with curing adhesive.

[0009] When an adhesive layer is pasted inside the slotted area, the adhesive layer has a first surface on the side away from the display panel, and the flexible support layer has a second surface on the side away from the display panel. The difference between the first surface and the second surface in the direction perpendicular to the display panel is less than or equal to a first threshold.

[0010] For example, the flexible support layer further includes a third surface opposite to the second surface; wherein

[0011] At least a portion of the slotted area is configured as a through slot penetrating the second surface and the third surface to expose a portion of the adhesive layer, and the adhesive layer is adhered to the exposed portion of the adhesive layer on the side closer to the display panel;

[0012] and / or

[0013] At least a portion of the slotted area is configured as a recessed groove that does not penetrate the second surface and the third surface, and the adhesive layer is adhered to the recessed surface of the recessed groove facing away from the display panel;

[0014] and / or

[0015] At least a portion of the slotted area is configured such that a portion extends through the second surface and the third surface to expose a portion of the adhesive layer, and another portion has a recess; the adhesive layer includes a first region and a second region, the first region being adhered to the exposed portion of the adhesive layer, and the second region being adhered to the recessed surface of the recess opposite to the display panel.

[0016] For example, when at least a portion of the slotted area is configured to extend through the second and third surfaces to expose a portion of the adhesive layer, and another portion has a recess, the first area has a first thickness in the direction perpendicular to the display panel, the second area has a second thickness in the direction perpendicular to the display panel, and the recess has a third thickness in the direction perpendicular to the display panel, wherein the difference between the sum of the second and third thicknesses and the first thickness is less than or equal to a second threshold.

[0017] For example, there is a gap between the adhesive layer and the sidewall of the grooved area.

[0018] For example, the gap is greater than or equal to 0.2 mm.

[0019] For example, the adhesive layer includes stretchable adhesive tape.

[0020] For example, the flexible support layer includes a support body layer and a first protective film attached to the support body layer on the side opposite to the display panel; the adhesive layer includes an adhesive tape body layer and a second protective film attached to the adhesive tape body layer on the side opposite to the display panel.

[0021] For example, the flexible support layer has a protruding first tear-off portion at least on one side edge, the first tear-off portion being used to facilitate the tearing operation of the first protective film and the support body layer under external force; and / or

[0022] The adhesive layer has a protruding second tear handle at least on one side edge, which is used to facilitate the tearing of the second protective film and the supporting body layer under external force.

[0023] For example, the flexible support layer includes a central region and a peripheral region located around the central region, with at least a portion of the slotted area located in the peripheral region and extending along a portion of the edge of the flexible support layer.

[0024] For example, the flexible support layer includes a first side corresponding to the bonding side of the display panel, and other sides besides the first side, wherein the slotted area extends along a portion of the edge of the other sides.

[0025] For example, in the slotted area extending along a portion of the edge of the flexible support layer, the adhesive layer is flush with the outer surface of the bonding adhesive layer.

[0026] For example, when the grooved area is configured such that the interior of the grooved area can be filled with cured adhesive, the flexible support layer also includes a third surface opposite to the second surface, and the grooved area is a recessed groove that does not penetrate the second surface and the third surface.

[0027] For example, the recessed groove has a trapezoidal cross-section in the direction perpendicular to the display substrate, and the groove opening dimension is smaller than the inner bottom dimension of the recessed groove in the direction parallel to the display panel.

[0028] Secondly, embodiments of this disclosure provide a display device, including the display module described above.

[0029] The beneficial effects of the embodiments disclosed herein are as follows:

[0030] In the above solution, the flexible support layer in the display module has a slotted area. That is, the flexible support layer is designed with slots and / or windows, and an adhesive layer is pasted or subsequently filled with curing adhesive in the slotted area. It is ensured that the gap between the adhesive layer and the flexible support layer on the side away from the display panel is less than or equal to a first threshold. This ensures that the gap between the adhesive layer and the flexible support layer meets the bonding process requirements. Therefore, in the subsequent bonding process, when bonding the display module to components such as the heat dissipation film, it is not necessary to separately apply adhesive tape or foam glue on the side of the flexible support layer away from the display panel. The bonding and assembly of components such as the heat dissipation film can be completed directly using the adhesive layer, thereby reducing the overall thickness. Furthermore, since the separate application of adhesive tape or foam glue is eliminated, the tape bonding process on the client side is reduced. At the same time, since the gap between the adhesive layer and the flexible support layer meets the bonding process requirements, the bonding yield of the entire product can be guaranteed.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

The terms “upper,” “lower,” “left,” and “right,” etc., are used only to indicate relative positional relationships, and these relative positional relationships may change accordingly when the absolute position of the described objects changes.

[0041] Before providing a detailed description of the display module and display device provided in the embodiments of this disclosure, it is necessary to explain the related technologies as follows:

[0042] In related technologies, for large-size flexible display products, the display module structure is as follows: Figure 1As shown. The display module may include a display panel 1, an adhesive layer 2, and a flexible support layer 3. The adhesive layer 2 may include a buffer layer (EMBO) and a foam adhesive layer. The buffer layer and the foam adhesive layer are bonded to the flexible support layer 3 at the die-cutting plant, and then bonded to the display panel 1.

[0043] To match the customer's complete device, the client uses adhesive tape to bond the heat dissipation film (SCF), mid-frame, and other components of the display module to the complete device. Furthermore, to reduce film marks that may occur during assembly and bonding, the client adds foam at the bonding points between the flexible support layer 3 on the complete device and the heat dissipation film and other components to further reduce mold marks. However, reducing the overall thickness of the device remains a key requirement for the client.

[0044] To address the aforementioned issues, this disclosure provides a display module and display device that can reduce the overall thickness and streamline assembly processes.

[0045] like Figures 2 to 6 As shown, the display module provided in this embodiment includes: a display panel 100, an adhesive layer 200, and a flexible support layer 300. The display panel 100 includes a light-emitting side and a backlight side. The adhesive layer 200 can be adhered to the backlight side of the display panel 100, and the flexible support layer 300 is adhered to the side of the adhesive layer 200 opposite to the display panel 100 via the adhesive layer 200. The flexible support layer 300 has a slotted area 310, and the slotted area 310 is configured such that an adhesive layer 400 (e.g., ...) is adhered inside the slotted area 310. Figures 2 to 5 (as shown), and / or the interior of the grooved area 310 may be filled with curing adhesive 500 (such as... Figure 6 (as shown); wherein, when the adhesive layer 400 is pasted inside the slotted area 310, the adhesive layer 400 has a first surface on the side away from the display panel 100, and the flexible support layer 300 has a second surface on the side away from the display panel 100, and the difference between the first surface and the second surface in the direction perpendicular to the display panel 100 is less than or equal to a first threshold.

[0046] In the above scheme, the flexible support layer 300 in the display module is provided with a slotted area 310, that is, the flexible support layer 300 is designed with slots and / or windows, and the adhesive layer 400 is pasted in the slotted area 310 or subsequently filled with curing adhesive 500. For the case where the adhesive layer 400 is pasted in the slotted area 310, it can be ensured that the gap between the adhesive layer 400 and the flexible support layer 300 on the side away from the display panel 100 is less than or equal to a first threshold, so that the gap between the adhesive layer 400 and the flexible support layer 300 meets the requirements of the adhesive layer 400. In accordance with process requirements, when bonding the display module and other components such as the heat dissipation film in subsequent bonding processes, it is not necessary to separately apply adhesive tape or foam adhesive on the side of the flexible support layer 300 opposite to the display panel 100. The bonding adhesive layer 400 can be used directly to complete the bonding and assembly of components such as the heat dissipation film, thereby reducing the overall thickness of the device. Furthermore, since the separate application of adhesive tape or foam adhesive is eliminated, the tape bonding process on the client side is reduced. At the same time, since the gap between the bonding adhesive layer 400 and the flexible support layer 300 meets the bonding process requirements, the bonding yield of the entire product can be guaranteed.

[0047] It should be noted that in practical applications, the bonding process between the flexible support layer 300 and the heat dissipation film is usually completed at the client end. However, with the display module provided in this embodiment, since the flexible support layer 300 has a slotted area 310 and the bonding adhesive layer 400 is pasted in the slotted area 310, the separate tape bonding process at the client end can be eliminated, which can improve the competitiveness of the display module product.

[0048] It should be noted that in the above scheme, the difference in thickness between the first surface and the second surface in the direction perpendicular to the display panel 100 is less than or equal to a first threshold. Specifically, in one embodiment, there is no thickness difference between the adhesive layer 400 and the flexible support layer 300, and their surfaces on the side facing away from the display panel 100 are approximately flush, to ensure that bonding defects do not occur during the bonding process due to a thickness difference between the adhesive layer 400 and the flexible support layer 300. For example, the first threshold may be less than 10% of the thickness of the flexible support layer 300.

[0049] It is understandable that, in other embodiments, the specific value of the first threshold may be adapted according to the specific structure of the component to be bonded to the display module on the side where the flexible support layer 300 is located.

[0050] In addition, such as Figure 6As shown, in the case where the slotted area 310 is configured to be filled with curing adhesive 500, the curing adhesive 500 can be any suitable material such as hot melt adhesive. The client can use the curing adhesive 500 to connect the entire machine and the display module. Specifically, the client can apply the curing adhesive 500 to the slotted area 310 and then bond it to the entire machine, thereby reducing the overall thickness of the machine and increasing the reliability of the connection between the machine and the display module.

[0051] In some embodiments, the flexible support layer 300 can be made of any suitable material such as thin stainless steel sheet (SUS). The slotted area 310 of the flexible support layer 300 can be achieved by patterning the flexible support layer 300. For example, when the flexible support layer 300 is SUS, the SUS can be slotted or windowed by cutting or other methods to obtain the slotted area 310.

[0052] When the adhesive layer 400 is provided within the grooved area 310, the specific structure and connection relationship between the grooved area 310 and the adhesive layer 400 can be varied. Examples are given below:

[0053] In some embodiments, the adhesive layer 200 may include a buffer layer (EMBO) and a foam layer for attaching the flexible support layer 300 to the backlight side of the display panel 100. For example... Figures 2 to 5 As shown, the display module may further include a polarizer 500, an optical adhesive layer 700, and a protective cover plate 800, which are stacked sequentially on the light-emitting side of the display panel 100.

[0054] Furthermore, in some embodiments, such as Figure 3 As shown, the flexible support layer 300 also includes a third surface opposite to the second surface; wherein at least a portion of the slotted area 310 is configured as a through-groove penetrating the second surface and the third surface to expose a portion of the adhesive layer 200, and the adhesive layer 400 is adhered to the exposed portion of the adhesive layer 200 on the side closer to the display panel 100. That is, at least a portion of the slotted area 310 can be a through-groove, and the adhesive layer 400 can be located within the slotted area 310 and adhered to the exposed portion of the adhesive layer 200. This structure is simple and the process is easy to implement.

[0055] In other embodiments, such as Figure 4As shown, the flexible support layer 300 also includes a third surface opposite to the second surface; at least a portion of the slotted area 310 is configured as a recessed groove that does not penetrate the second surface and the third surface, and the adhesive layer 200 is adhered to the recessed surface 311 of the recessed groove that is opposite to the display panel 100. That is, at least a portion of the slotted area 310 does not penetrate the flexible support layer 300 but retains a recessed surface 311, which is the inner bottom surface of the recessed groove, and the adhesive layer 400 can be located within the slotted area 310 and adhered to the recessed surface 311.

[0056] In other embodiments, such as Figure 5 As shown, at least a portion of the slotted area 310 is configured such that a portion extends through the second surface and the third surface to expose a portion of the adhesive layer 200, and another portion has a recess; the adhesive layer 400 includes a first region 410 and a second region 420, the first region 410 being adhered to the exposed portion of the adhesive layer 200, and the second region 420 being adhered to the recessed surface 311 of the recess, which faces away from the display panel 100. That is, as shown, the recessed surface 311 can form a stepped structure of the slotted area 310, and the adhesive layer 400 can be partially adhered to the adhesive layer 200 and partially adhered to the recessed surface 311.

[0057] It should be noted that there can be multiple slotted areas 310, and each slotted area 310 can have the same structure, as shown in the figure. Figure 3 The through slot shown, such as Figure 4 The sinkhole shown or as Figure 5 The partially through-type and partially retainable sinking platform structure shown can also be a combination of any two of the above-mentioned through-type, sinking platform, or partially through-type and partially retainable sinking platform structures, where multiple slotted areas 310 adopt such structures.

[0058] In some exemplary embodiments, the adhesive layer 400 can be adhesive tape. More specifically, it can be stretch adhesive tape. This allows the adhesive layer 400 to be easily applied to the slotted area 310, facilitating operation. Furthermore, using stretch adhesive tape allows for easy removal of the entire machine after assembly by the client, simplifying disassembly. It is understood that the adhesive layer 400 is not limited to stretch adhesive tape.

[0059] In some embodiments, taking into account fit tolerances, Figures 2 to 5As shown in the example, there is a gap a between the adhesive layer 400 and the sidewall of the grooved area 310, so that the adhesive layer 400 and the grooved area 310 do not contact each other, ensuring a good bonding yield. For example, the gap a is greater than or equal to 0.2 mm.

[0060] Furthermore, in some embodiments, for Figure 5 The slotted area 310 structure shown has a first area 410 having a first thickness h1 in the direction perpendicular to the display panel 100, a second area 420 having a second thickness h2 in the direction perpendicular to the display panel 100, and a recessed platform having a third thickness h3 in the direction perpendicular to the display panel 100. The difference between the sum of the second thickness h2 and the third thickness h3 and the first thickness h1 is less than or equal to a second threshold.

[0061] It should be noted that the difference between the sum of the second thickness h2 and the third thickness h3 and the first thickness h1 is less than or equal to the second threshold. Specifically, in one embodiment, the first region 410 and the second region 420 are approximately flush on the surface opposite to the display panel 100 to ensure that bonding defects do not occur due to a thickness difference between the first region 410 and the second region 420 during the bonding process. For example, the second threshold can be 1 / 3 of the thickness of the flexible support layer 300.

[0062] In some embodiments, in order to ensure that the first region 410 and the second region 420 are substantially flush on the side of the display panel 100 away from the adhesive layer 400, two adhesive tapes of different thicknesses can be selected for the adhesive layer 400. As shown in the figure, the adhesive layer 400 may include a first adhesive tape 410a and a second adhesive tape 420a. The first adhesive tape has a first thickness h1 and the second adhesive tape has a second thickness h2. The first adhesive tape 410a is pasted onto the exposed portion of the adhesive layer 200 to form the first region 410; the second adhesive tape 420a is pasted onto the recessed surface 311 of the recessed platform away from the display panel 100 to form the second region 420.

[0063] It is understandable that the adhesive layer 400 can also be an adhesive tape of a certain thickness. In some embodiments, the third thickness h3 of the sinking platform can be within the second threshold, that is, the third thickness h3 of the sinking platform is less than or equal to 1 / 3 of the thickness of the flexible support layer 300, so as to ensure that the discontinuity between the first region 410 and the second region 420 is less than or equal to the second threshold.

[0064] In some exemplary embodiments, such as Figure 2 and Figure 7As shown, the flexible support layer 300 includes a support body layer 300a and a first protective film 300b attached to the support body layer 300a on the side opposite to the display panel 100; the adhesive layer 400 includes an adhesive tape body layer 400a and a second protective film 400b attached to the adhesive tape body layer 400a on the side opposite to the display panel 100.

[0065] In the above solution, protective films are respectively provided on the adhesive layer 400 and the flexible support layer 300. During the client's bonding and assembly, the bonding and assembly between the display module and the heat dissipation film to be bonded can be completed simply by peeling off the protective film. The difference between the sum of the thicknesses of the support body layer 300a and the first protective film 300b and the sum of the thicknesses of the adhesive body layer 400a and the second protective film 400b is within the first threshold value to ensure that poor bonding impressions do not occur due to thickness differences during the bonding process.

[0066] For example, such as Figure 2 As shown, the flexible support layer 300 has a protruding first tear handle 300c at least on one side edge, the first tear handle 300c being used to facilitate the tearing operation of the first protective film 300b and the support body layer 300a under external force; and / or the adhesive layer 400 has a protruding second tear handle 400c at least on one side edge, the second tear handle 400c being used to facilitate the tearing operation of the second protective film 400b and the support body layer 300a under external force.

[0067] Furthermore, in some exemplary embodiments, such as Figure 2 As shown, the flexible support layer 300 includes a central region and a peripheral region located around the central region. At least a portion of the slotted area 310 is located in the peripheral region and extends along a portion of the edge of the flexible support layer 300.

[0068] By adopting the above solution, the flexible support layer 300 is extended along a portion of the edge in the surrounding area, which ensures the overall fit of the machine and avoids loose edge fit.

[0069] As an exemplary embodiment, such as Figure 2 As shown, a flexible circuit board (PCB) is bonded to the bonding side of the display panel 100. The flexible support layer 300 includes a first side A corresponding to the bonding side of the display panel 100, and other sides besides the first side A. The slotted area 310 extends along a portion of the edge of the other sides. It is understood that in some embodiments, the slotted area 310 may be provided not only in the peripheral area but also in the central area.

[0070] Furthermore, in some exemplary embodiments, such as Figure 3 and Figure 5 As shown, when the adhesive layer 400 is attached to the exposed portion of the adhesive layer 200, the adhesive layer 400 is flush with the outer surface of the adhesive layer 200 within the grooved area 310 extending along a portion of the edge of the flexible support layer 300.

[0071] In the above scheme, the bonding adhesive layer 400 and the adhesive layer 200 can be cut together with a tool to ensure a flush edge design.

[0072] It should be noted that, in Figure 4 In other embodiments shown, when the slotted area 310 is a recessed groove and the slotted area 310 is located in the peripheral area extending along the edge of the flexible support layer 300, the adhesive layer 200 is not exposed, and the bonding adhesive layer 400 is completely bonded to the recessed area. Therefore, the bonding adhesive layer 400 and the adhesive layer 200 cannot be cut integrally. Considering the bonding tolerance, the outer edge of the recessed area 310 should extend beyond the outer edge of the adhesive layer 200. That is, the adhesive layer 200 is designed to be recessed from the shape of the slotted area 310. For example, the recessed dimension a' ≥ 0.2 mm.

[0073] It should be noted that, compared to the design of the slotted area 310 as a through groove, the design of the slotted area 310 as a recessed groove can withstand greater bonding pressure.

[0074] As an exemplary embodiment, when the grooved area 310 is configured such that the interior of the grooved area 310 can be filled with cured adhesive 500, the flexible support layer 300 further includes a third surface opposite to the second surface, and the grooved area 310 is a recessed groove that does not penetrate the second surface and the third surface.

[0075] Using the above solution, when the slotted area 310 is configured to be filled with curing adhesive 500, the curing adhesive 500 can be any suitable material such as hot melt adhesive. The client can use the curing adhesive 500 to connect the entire machine and the display module. Specifically, the client can apply the curing adhesive 500 to the slotted area 310 and then bond it to the entire machine, thereby reducing the overall thickness of the machine and increasing the reliability of the connection between the machine and the display module.

[0076] To ensure reliable fit, in some exemplary embodiments, such as Figure 6As shown, the recessed groove has a trapezoidal cross-section in the direction perpendicular to the display substrate. In the direction parallel to the display panel 100, the groove opening is smaller than the inner bottom surface of the recessed groove, which ensures that the curing adhesive 500 can flow fully into the grooved area 310.

[0077] It should be noted that in some embodiments, a grooved area can be set in the peripheral area of ​​the flexible support layer 300 and the adhesive layer 400 can be pasted thereon, while a grooved area can be set in the middle area of ​​the flexible support layer 300 for filling with cured adhesive 500.

[0078] The display panel 100 in the display module provided in this embodiment can be an OLED display panel 100, but is not limited to an OLED display panel 100.

[0079] Furthermore, in a second aspect, embodiments of this disclosure provide a display device, including the display module provided in embodiments of this disclosure.

[0080] As shown in the figure, in some embodiments, the display device further includes a heat dissipation film 600 attached to the side of the flexible support layer 300300 facing away from the display panel 100, wherein the heat dissipation film 600 is attached to the flexible support layer 300 through the adhesive layer 400.

[0081] The following points need to be explained:

[0082] (1) The accompanying drawings of the embodiments of this disclosure only involve the structures involved in the embodiments of this disclosure. Other structures can be referred to the general design.

[0083] (2) For clarity, the thickness of layers or regions is enlarged or reduced in the drawings used to describe embodiments of the present disclosure, i.e., these drawings are not drawn to actual scale. It will be understood that when an element such as a layer, film, region or substrate is referred to as being “above” or “below” another element, the element may be “directly” located “above” or “below” the other element or there may be intermediate elements.

[0084] (3) Where there is no conflict, the embodiments of this disclosure and the features in the embodiments can be combined with each other to obtain new embodiments.

[0085] The above are merely specific embodiments of this disclosure, but the scope of protection of this disclosure is not limited thereto. The scope of protection of this disclosure shall be determined by the scope of the claims.
