Description

Technical Field

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

[0002] With the continuous development of science and technology, more and more display products, such as mobile phones, tablets, laptops and smart wearable devices, are being widely used in people's daily lives and work, bringing great convenience to people's daily lives and work, and becoming an indispensable tool for people today.

[0003] The production process of display products involves multiple quality inspection procedures. However, due to the structural characteristics of display products themselves, it is difficult to avoid the problem of missed inspections in certain areas. Summary of the Invention

[0004] To address the aforementioned technical issues, this disclosure provides a display module and display device that helps avoid missed detections regarding the application of shielding film.

[0005] In a first aspect, this disclosure provides a display module, including:

[0006] The display panel includes a first bonding area disposed on a non-light-emitting surface, wherein a first device is bonded to the first bonding area;

[0007] The shielding film is located on the non-light-emitting surface and covers at least the first bonding area and the first device;

[0008] The protective film is located on the non-light-emitting surface and on the side of the shielding film away from the first device; the protective film includes a visual area, which overlaps with the shielding film along a first direction, which is perpendicular to the light-emitting surface of the display panel.

[0009] Secondly, based on the same inventive concept, this disclosure provides a display device, including the display module provided in the first aspect of this disclosure.

[0010] The technical solution provided in this disclosure has the following advantages compared with the prior art:

[0011] In the display module and display device provided in this disclosure, the first bonding area is located on the non-light-emitting surface of the display panel. For example, it can be bent to the non-light-emitting surface of the display panel to achieve a narrow bottom bezel design. By covering the first bonding area and the location of the first device with a shielding film, it is beneficial to reduce or avoid the adverse effects of static electricity on the first bonding area and the first device, thereby improving the anti-static performance of the display product. A protective film is introduced on the side of the shielding film away from the first device to support and protect the first device. In particular, a visualization area is introduced in the protective film of this disclosure. Along the first direction, that is, the direction perpendicular to the light-emitting surface of the display panel, the visualization area overlaps with the shielding film. Thus, the adhesion of the shielding film can be observed through the visualization area of ​​the protective film. Since the adhesion of the shielding film directly affects the anti-static performance of the product, if the shielding film has wrinkles or other problems, the shielding effect against static electricity will be greatly weakened. Therefore, this disclosure introduces a visualization area in the protective film, which allows inspectors to observe whether there are any abnormalities in the adhesion of the shielding film. This enables timely interception of products with poorly adhered shielding films, thereby improving the yield of the final product and solving the problem of missed detection of shielding film adhesion in related technologies.

[0024] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0025] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0026] In related technologies, to achieve a narrow bezel design in display products, the bonding area where control chips or flexible circuit boards are bonded is typically folded back to the non-light-emitting surface of the display product, thus achieving a narrow bottom bezel design. Exposed electronic components in the bonding area reduce the product's anti-static capability. Therefore, conductive cloth can be attached to the bonding area on the non-light-emitting surface of the display product to improve its anti-static performance. Furthermore, an injection-molded bracket can be introduced on the side of the conductive cloth away from the bonding area to support it. Typically, a black modified material is added to the injection-molded bracket. After the bracket is assembled, the actual adhesion of the conductive cloth beneath it cannot be observed, leading to missed detection issues regarding the conductive cloth's adhesion.

[0027] To address this issue, this disclosure provides a display module and display device to avoid missed detections regarding the adhesion of the shielding film. The disclosure will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0028] Figure 1 The image shown is a plan view of a display module provided in this disclosure. Figure 2 As shown Figure 1 The image shows a cross-sectional view of the module along the AA' direction. Figure 3 The figure shown is another planar schematic diagram of the display module provided in this disclosure. Figure 4 As shown Figure 3 The image shows a cross-sectional view of the module along the BB' direction.

[0029] Please refer to Figures 1 to 4 The present disclosure provides a display module 100, comprising:

[0030] The display panel 10 includes a first bonding area Q1 disposed on its non-light-emitting surface, wherein a first device 20 is bonded to the first bonding area Q1; wherein the first device 20 may be, for example, an electronic device such as a control chip or a PCB board, and this disclosure does not specifically limit it. Figure 1 and Figure 3 The shape and size of the first bonding area and the shape and size of the first device are for illustrative purposes only and are not intended to limit this disclosure. The non-light-emitting surface of the display panel refers to the surface opposite to the light-emitting side of the display panel, and can also be understood as the back of the display panel.

[0031] The shielding film 30 is located on the non-light-emitting surface and at least covers the first bonding area Q1 and the first device 20; optionally, the shielding film 30 is a conductive cloth used to shield against static electricity. The specific structure of the conductive cloth can be found in related technologies, and will not be described in detail here.

[0032] The protective film 40 is located on the non-light-emitting surface and on the side of the shielding film 30 opposite to the first device 20. The protective film 40 includes a viewing area that overlaps with the shielding film 30 along a first direction F1, where the first direction F1 is perpendicular to the light-emitting surface of the display panel 10. The viewing area refers to the light-transmitting area of ​​the protective film, through which the adhesion to the shielding film can be observed. Optionally, the area of ​​the viewing area in the protective film is larger than the coverage area of ​​the shielding film 30, so that the adhesion of the edge of the shielding film can be observed through the viewing area.

[0033] In the display module provided in this embodiment, the first bonding area Q1 is located on the non-light-emitting surface of the display panel 10. For example, it can be bent to the non-light-emitting surface of the display panel 10 to achieve a narrow bottom bezel design. By covering the first bonding area Q1 and the location of the first device 20 with a shielding film 30, it is beneficial to reduce or avoid the adverse effects of static electricity on the first bonding area Q1, the first device 20, and other electronic devices located on the non-light-emitting surface, thereby improving the anti-static performance of the display product. A protective film 40 is introduced on the side of the shielding film 30 away from the first device 20 to support and protect the first device 20 and the bending area. In particular, a visualization area is introduced in the protective film 40 of this disclosure. Along the first direction F1, that is, the direction perpendicular to the light-emitting surface of the display panel 10, the visualization area overlaps with the shielding film 30. Thus, the adhesion of the shielding film 30 can be observed through the visualization area of ​​the protective film 40. Since the adhesion of the shielding film 30 directly affects the antistatic performance of the product, if the shielding film 30 has wrinkles or other problems, its shielding effect against static electricity will be greatly reduced. Therefore, this disclosure introduces a visualization area in the protective film 40. Inspectors can observe whether there are any abnormalities in the adhesion of the shielding film 30 through this visualization area, and promptly intercept products with poorly adhered shielding film 30, thereby improving the yield of the final product and solving the problem of missed detection of shielding film 30 adhesion in related technologies.

[0034] The protective film 40 in this disclosure includes a visible area. One feasible implementation is that a portion of the protective film 40 is transparent and visible, for example, the area overlapping with the shielding adhesive film 30 is transparent and visible, while other areas are not visible. Another feasible implementation is that the entire protective film 40 is transparent and visible. The requirement is that the adhesion of the shielding adhesive film 30 can be observed through the protective film 40.

[0035] It should be noted that this disclosure does not limit the type of display panel 10 in the display module. The display panel 10 can be an organic electroluminescent display panel (e.g., an OLED display panel), an inorganic light-emitting diode display panel (e.g., a Micro LED or Mini LED display panel), a liquid crystal display panel, etc. Figure 1 and Figure 2 The corresponding display panel 10 is a flexible display panel, which can be an organic electroluminescent display panel or an inorganic light-emitting diode display panel. In this type of display panel, the light-emitting element is self-emissive, and there is no need to introduce a backlight module, which is conducive to realizing the thin design of display products. Figure 3 and Figure 4The corresponding display panel 10 is a liquid crystal display panel. In addition to the display panel 10, the display module also includes a backlight module 90. This embodiment shows a scheme in which the display panel 10 and the backlight module 90 correspond to different first devices 20. For example, the first device 20 connected to the display panel 10 is a display driving device 21, and the first device 20 corresponding to the backlight module is a backlight driving device 22. In this case, the shielding film 30 will cover both types of first devices 20. Of course, in some other embodiments of this disclosure, the above-mentioned display panel 10 and backlight module 90 may also correspond to the same first device 20, and this disclosure does not specifically limit this.

[0036] It should also be noted that, Figure 1 and Figure 3 This illustration only shows the top view of the display module and does not limit the actual shape and size of the display module. It should be noted that the figures in this embodiment are merely illustrative of the display module's structure. In actual implementation, the display module may also include other structures capable of displaying functions, such as sub-pixels, scanning drive circuits, and surrounding lines, etc., which will not be elaborated upon in this embodiment. The display module in this disclosure does not limit the structure of sub-pixels and the pixel circuits included within them; for specific understanding, please refer to the structure of display panels in related technologies. Furthermore, Figure 2 and Figure 4 This illustration only shows a portion of the film layer structure of the display module. In actual implementation, the display module also includes other film layers. For example, for OLED display panels, there are also driving layers, light-emitting functional layers, pixel definition layers, cathode layers, encapsulation layers, etc. This embodiment will not elaborate on these layers. Other film layer structures can be understood by referring to the film layer structure of organic light-emitting diodes in related technologies.

[0037] Please refer to Figures 1 to 4 In one optional embodiment of this disclosure, the protective film 40 is entirely made of a transparent material. This makes the entire protective film 40 a transparent structure, eliminating the need to distinguish between transparent and non-transparent areas, thus simplifying the manufacturing process. Optionally, the protective film 40 can be made of transparent PET (Polyethylene terephthalate), a thermoplastic polyester. Using this material as the protective film 40 in this disclosure gives it excellent heat resistance, mechanical, chemical, and electrical insulation properties. Of course, in other embodiments of this disclosure, the protective film 40 can also be made of transparent PE (polyethylene) or transparent PVC (polyvinyl chloride), etc., and this disclosure does not specifically limit its use.

[0038] In one optional embodiment of this disclosure, the protective film 40 is manufactured using a die-cutting process. Protective films in related technologies are typically formed into black sheet-like structures using injection molding, while the protective film 40 in this disclosure is manufactured using a die-cutting process. Die-cutting is easier to process than injection molding, has a shorter production cycle, and lower costs. Therefore, the method of manufacturing the protective film using a die-cutting process in this disclosure is beneficial for both improving production efficiency and reducing production costs.

[0039] Please refer to Figure 2 and Figure 4 In one optional embodiment of this disclosure, the thickness of the protective film 40 is D0, where 0.3 mm ≤ D0 ≤ 0.5 mm. As a component of the display product, the thickness of the protective film 40 is closely related to the final thickness of the display product. When this disclosure uses a transparent material, such as transparent PET, to make the protective film, the thickness of the protective film 40 can be controlled to 0.5 mm or less, which is much smaller than the thickness of the protective film 40 made using injection molding in related technologies. Therefore, using a thinner protective film is beneficial to meeting the thinning requirements of the display product. Furthermore, considering that if the thickness of the protective film 40 is too thin, for example, less than 0.3 mm, the supporting capacity of the protective film will decrease, and the protection capability for the first device 20 will also decrease, when the thickness of the protective film 40 is set to be greater than or equal to 0.3 mm, the edge warping of the protective film 40 can be ensured to be within 1 mm, thereby ensuring that the protective film 40 has good supporting capacity and thus achieving effective protection for the first device 20. In practical applications, the thickness of the protective film 40 can be 0.3mm to 0.4mm (inclusive of the endpoint value), or 0.4mm to 0.5mm (inclusive of the endpoint value), etc. This disclosure does not make specific limitations on this.

[0040] Figure 5 As shown Figure 3 The image shows another cross-sectional view of the module along the BB' direction. Figure 6 The diagram shown illustrates the relative positional relationship between the protective film 40 and the support column provided in this disclosure. Please refer to the diagram for further details. Figures 1 to 6 In one optional embodiment of this disclosure, the display module provided by this disclosure further includes a foam support column 50. Along the first direction F1, the foam support column 50 is located between the protective film 40 and the shielding film 30, and the foam support column 50 is fixed to the surface of the protective film 40 facing the shielding film 30. The foam support column 50 creates a first gap between the protective film 40 and the shielding film 30, and the height of the first gap is greater than zero.

[0041] It should be noted that the surface of the display module with the shielding film 30 attached may not be a flush surface. For example, please refer to... Figure 5When the protective film 40 is introduced on the side of the shielding film 30 away from the first device 20, the height of the foam support column 50 introduced between the protective film 40 and the aforementioned non-flush surface can be set differently according to the actual situation, so as to ensure that the surface of the protective film 40 away from the foam support column 50 is parallel to the light-emitting surface of the display module, thereby facilitating the subsequent assembly of the whole machine.

[0042] During the assembly of the display module, the foam support pillar 50 can be pre-fixed to one side surface of the protective film 40. Specifically, the two can be fixed by adhesive, for example, at least one side surface of the foam support pillar 50 is adhesive, and this adhesive surface can be attached to the protective film 40. When assembling the protective film 40, the surface of the protective film 40 with the foam support pillar 50 attached faces the shielding film 30. The foam support pillar 50 has a certain thickness, and when the protective film 40 is placed on one side of the shielding film 30, the foam support pillar 50 creates a first gap between the protective film 40 and the shielding film 30, thereby preventing direct contact between the protective film 40 and the shielding film 30, and preventing the protective film 40 from touching the first device 20 through the shielding film 30 when subjected to external force, thus preventing damage to the first device 20.

[0043] Please refer to this appropriately. Figure 5 In one optional embodiment of this disclosure, along the first direction F1, the minimum distance between the surface of the protective film 40 facing the shielding film 30 and the surface of the shielding film 30 facing the protective film 40 is D1, where D1 ≥ 1 mm. As mentioned above, the surface of the display module to which the shielding film 30 is attached may not be a flat surface. In this embodiment, when a foam support column 50 is introduced between the protective film 40 and the shielding film 30, the width of the minimum gap between the highest point of the surface of the display module to which the shielding film 30 is attached and the surface of the protective film 40 facing the shielding film 30 is greater than or equal to 1 mm. This ensures that the highest point of the uneven surface is also spaced from the protective film 40. Even if the protective film 40 is subjected to external force and may move towards the shielding film 30, this gap of 1 mm or more can provide space for the movement of the protective film 40, preventing the protective film 40 from contacting the shielding film 30, and thus preventing the protective film 40 from contacting the first device 20, which is more conducive to achieving the protection function of the first device 20.

[0044] Continue to refer to Figure 6 and combined Figures 1 to 4 In one optional embodiment of this disclosure, the shielding film 30 includes an edge region, and the foam support column 50 includes a first support column 51. Along the first direction F1, the first support column 51 overlaps with the edge region of the shielding film 30.

[0045] Since the surface on which the shielding film 30 needs to be attached in the display module is not a flat surface—for example, the area where the first device 20 is located may be higher than other surrounding areas—when the shielding film 30 is attached to the position corresponding to the first device 20, the edge of the shielding film 30 is attached to the outer periphery of the first device 20. When the shielding film 30 is attached to an uneven surface, wrinkles may occur at its edge, and the presence of wrinkles greatly weakens the antistatic capability of the shielding film 30. Therefore, when a foam support post 50 is introduced between the protective film 40 and the shielding film 30, at least a portion of the foam support post 50 (corresponding to the aforementioned first support post 51) can be placed at the edge of the shielding film 30, and the foam support post 50 abuts against the edge area of ​​the shielding film 30 to avoid wrinkles in this part of the shielding film 30. Thus, the foam support post 50 introduced in this disclosure not only works with the protective film 40 to protect the first device 20, but also abuts against the edge area of ​​the shielding film 30 to ensure the shielding performance of the shielding film 30 against static electricity.

[0046] It should be noted that, please refer to... Figures 1 to 6 When setting the foam support pillar 50, the foam support pillar 50 is located in the clearance area of ​​the non-light-emitting surface of the display panel 10. That is to say, no electronic components are placed at the position where the film layer bent to the non-light-emitting surface of the display panel 10 contacts the foam, thereby avoiding damage to the electronic components when the foam support pillar 50 is under pressure. In practical applications, if the edge area of ​​the shielding film 30 is a clearance area, the foam support pillar 50 can be used to cover each edge area of ​​the shielding film 30; if some areas of the edge area of ​​the shielding film 30 are not clearance areas, the foam support pillar 50 is not set in these areas, but only at the positions corresponding to the edges of the shielding film 30 in the clearance area.

[0047] It should also be noted that, Figure 6 The relative positional relationship between the protective film 40 and the foam support column 50 shown is for illustrative purposes only and does not represent the actual number and position of the foam support column 50. In practical applications, the number and position of the foam support column 50 can be flexibly adjusted.

[0048] Figure 7 The diagram shown illustrates another relative positional relationship between the protective film 40 and the support column provided in this disclosure, and is adapted for reference. Figures 1 to 4 , Figure 7 The location of the first device 20 is indicated by a dashed box. In an optional embodiment of this disclosure, the foam support column 50 includes a second support column 52. Along the first direction F1, the orthographic projection of the second support column 52 onto the plane of the shielding film 30 is located outside the orthographic projection of the first device 20 onto the plane of the shielding film 30; please refer to... Figure 2The height of the second support column 52 along the first direction F1 is H1, and the height of the first device 20 along the first direction F1 is H2, wherein H1 > H2.

[0049] This disclosure illustrates a scheme in which a second support post 52 is introduced around the first device 20. One end face of the second support post 52 contacts the periphery of the first device 20, and the other end face contacts the protective film 40, thereby supporting the protective film 40. In this embodiment, the height H1 of the second support column 52 is set to be greater than the height H2 of the first device 20. When the second support column 52 is placed on the shielding film 30, since the first device 20 is also covered with a shielding film, the sum of the height H1 of the second support column 52 and the thickness of the shielding film 30 is greater than the sum of the height H2 of the first device 20 and the thickness of the shielding film 30. The purpose is to make the end face of the second support column 52 facing away from the shielding film 30 extend beyond the surface of the shielding film 30 on the first device 20. In this way, a certain space is ensured between the surface of the protective film 40 facing the first device 20 and the shielding film 30 on the first device 20. The spacing width of this space is greater than or equal to 1 mm. Even when the protective film 40 is squeezed by external force, the aforementioned space can reserve a certain displacement space for the protective film 40, avoiding the protective film 40 from touching the shielding film 30 on the first device 20 and causing damage to the first device 20.

[0050] Please continue to refer to this. Figure 6 and Figure 7 In one optional embodiment of this disclosure, the second support column 52 is located at least on both sides of the first device 20 along the second direction F2, which is parallel to the light-emitting surface of the display panel 10. Optionally, the second direction F2 can be, for example, the length direction of the first device 20, or of course, the width direction or the oblique direction of the first device 20; this disclosure does not specifically limit this. The dashed boxes in the figure represent the corresponding positions of the first device 20.

[0051] Please combine them together Figure 2 and Figure 4 When the protective film 40 is subjected to uneven force, it may tilt slightly and touch the shielding film 30 above the first device 20, thus affecting the reliability of the first device 20. In this embodiment, when the second support column 52 in the foam support column 50 is provided on at least both sides of the first device 20 along the second direction F2, even if the protective film 40 is subjected to uneven force, since the second support column 52 is provided on both sides of the first device 20, the second support column 52 can also provide a certain support for the protective film 40, preventing the protective film 40 from tilting in the area corresponding to the first device 20 and affecting the reliability of the first device 20.

[0052] It should be noted that when the second support pillars 52 are introduced on both sides of the first device 20, the second support pillars 52 are also set in the clearance area, that is, bent into the film layer on the back of the display panel 10. No other electronic devices are set at the position where the second support pillars 52 overlap along the first direction F1, so as to avoid the introduction of the foam support pillars 50 from affecting the stability of the electronic devices.

[0053] Figure 8 The diagram shows another relative positional relationship between the protective film 40 and the support column provided in this disclosure. In an optional embodiment of this disclosure, the orthographic projection of the second support column 52 on the plane where the shielding film 30 is located surrounds or at least partially surrounds the orthographic projection of the first device 20 on the plane where the shielding film 30 is located.

[0054] Figure 7 The illustrated embodiment shows a scheme in which second support posts 52 are provided on both sides of the first device 20. For more reliable protection of the first device 20, please refer to [the following text is missing]. Figure 6 and Figure 8 In addition to providing second support columns 52 on both sides of the first device 20 along the second direction F2, a second support column 52 can also be provided on at least the other side of the first device 20, so that the second support column 52 is at least partially arranged around the first device 20. This arrangement is equivalent to introducing more support points around the first device 20 by using the second support column 52, which is more conducive to avoiding the situation where the protective film 40 directly above the first device 20 is tilted by force and damaged. Figure 6 The diagram illustrates a scheme in which the second support column 52 comprises multiple independent structures respectively disposed on different sides of the first device 20. Figure 8 The diagram illustrates a scheme where the second support column 52 is an integral structure positioned on three sides of the first device 20. Both configurations provide good protection for the first device 20. In practical applications, the structure of the second support column 52 can be flexibly configured according to the surrounding conditions of the first device 20. If the clearance area around the first device 20 is large, a large, continuous second support column 52 can be installed. If there is a non-clearance area, the second support column 52 is not installed in the non-clearance area, thus forming a structure similar to... Figure 6 The schemes show multiple independent structures.

[0055] In some other embodiments of this disclosure, if the area surrounding the first device 20 is a clear area, the second support column 52 can be configured as a closed structure surrounding the first device 20, for example... Figure 9 , Figure 9 The diagram shows another relative positional relationship between the protective film 40 and the support column provided in this disclosure. In this way, the surrounding area of ​​the first device 20 can be reliably supported by the second support column 52, which is more conducive to the protection of the first device 20.

[0056] Please refer to Figures 6 to 9 and combined Figure 2 and Figure 4 In one optional embodiment of this disclosure, the display panel 10 includes a bent portion 80 located on the side of the display module, and the protective film 40 includes a lug 41, which overlaps with the bent portion 80 along the first direction F1.

[0057] When the display panel 10 in the display module is a flexible display panel, the flexible display panel itself can be bent. For example, in the lower bezel area of ​​the display module, the display panel 10 can cause the first bonding area Q1, on which the first device 20 is bonded, to be bonded to its non-light-emitting surface. In this case, the bent portion 80 corresponds to the bent part of the display panel 10. When the display panel 10 in the display module is a liquid crystal display panel, the bent part is the flexible circuit board bonded to the display panel 10. The flexible circuit board causes the first bonding area Q1 on it to bend to the non-light-emitting surface of the display panel 10. The bent portion 80 itself is a flexible structure and is easily damaged when subjected to external forces. This disclosure provides a lug 41 at the edge of the protective film 40. When the protective film 40 is assembled into the display module, the position of the lug 41 corresponds to the position of the bent portion 80 of the display module. That is, along the first direction F1, the lug 41 overlaps with the bent portion 80. When subjected to external force, the lug 41 in the protective film 40 can buffer the external force and prevent the external force from acting on the bent portion 80, thereby effectively protecting the bent portion 80.

[0058] Please continue to refer to this. Figures 6 to 9 On the side opposite to the lug 41, the protective film 40 has a protrusion 42. A foam support post 50, which can be considered a third support post 53, is provided on the surface of the protrusion 42 facing the shielding film 30. Optionally, both ends of the third support post 53 are provided with an adhesive layer. One end is adhered to the aforementioned protrusion 42 via the adhesive layer, and the adhesive layer on the other end has a tear handle 70. When it is necessary to adhere it to the non-light-emitting surface of the display module, the tear handle 70 on the other end is removed to expose the adhesive layer and fix it to the aforementioned non-light-emitting surface, thereby fixing the protective film to the non-light-emitting surface of the display module. Optionally, except for the third support post 53, the other support posts of the foam support post 50 are all single-sided adhesive layer structures. The end with the adhesive layer is adhered to the protective film 40, and the end without the adhesive layer contacts the film layer bent to the non-light-emitting surface via the bending portion 80.

[0059] Based on the same inventive concept, this disclosure also provides a display device. Figure 10 The diagram shown is a structural schematic of a display device 200 provided in an embodiment of this disclosure. Please refer to it. Figure 10The display device 200 includes the display module 100 in any of the above embodiments. The display device 200 provided in this disclosure can be any electronic device with display function, such as a touch screen, mobile phone, tablet computer, laptop computer, e-reader, or television. The display device 200 provided in this disclosure has the beneficial effects of the display module 100 provided in this disclosure. For details, please refer to the specific descriptions of the display module 100 in the above embodiments; these descriptions will not be repeated here.

[0060] Understandable Figure 10 The rounded rectangle structure is used as an example to illustrate one shape of the display device 200. In some other embodiments of this disclosure, the display device 200 may also be embodied as a rectangle, a circle, an ellipse or any other feasible shape, and this disclosure does not specifically limit it in this regard.

[0061] In summary, the display module and display device provided in this disclosure achieve the following technical effects:

[0062] In the display module and display device provided in this disclosure, the first bonding area is located on the non-light-emitting surface of the display panel. For example, it can be bent to the non-light-emitting surface of the display panel to achieve a narrow bottom bezel design. By covering the first bonding area and the location of the first device with a shielding film, it is beneficial to reduce or avoid the adverse effects of static electricity on the first bonding area and the first device, thereby improving the anti-static performance of the display product. A protective film is introduced on the side of the shielding film away from the first device to support and protect the first device. In particular, a visualization area is introduced in the protective film of this disclosure. Along the first direction, that is, the direction perpendicular to the light-emitting surface of the display panel, the visualization area overlaps with the shielding film. Thus, the adhesion of the shielding film can be observed through the visualization area of ​​the protective film. Since the adhesion of the shielding film directly affects the anti-static performance of the product, if the shielding film has wrinkles or other problems, the shielding effect against static electricity will be greatly weakened. Therefore, this disclosure introduces a visualization area in the protective film, which allows inspectors to observe whether there are any abnormalities in the adhesion of the shielding film. This enables timely interception of products with poorly adhered shielding films, thereby improving the yield of the final product and solving the problem of missed detection of shielding film adhesion in related technologies.
