Detailed Implementation

[0031] The features and exemplary embodiments of various aspects of this application will now be described in detail. Numerous specific details are set forth in the following detailed description in order to provide a comprehensive understanding of this application. However, it will be apparent to those skilled in the art that this application can be implemented without some of these specific details. The following description of embodiments is merely intended to provide a better understanding of this application by illustrating examples thereof.

[0032] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0033] The display device includes a display module and a mid-frame. The display module includes some or all of the following components stacked together: a cover plate, a polarizer, a touch layer, a display panel, a back plate, an SCF (Super Clean Foam) composite film, and an electrostatic shielding layer (copper foil layer). To simulate the impact of static electricity on the display effect during use, an electric field excitation test is required on the display module. The specific test process involves applying a high voltage (e.g., 4KV) to the copper foil on the back plate and grounding the cover plate. After maintaining this for a certain period, the display is observed for any abnormalities. The inventors discovered that as the negative charge on the cover plate surface is conducted along the edge of the display module to the back plate, it can easily cause changes in the electrical properties of the transistors in the array substrate of the display panel, leading to display abnormalities around the display panel. Simultaneously, as the mid-frame of the display device narrows, the adhesive connecting the cover plate and the mid-frame may overlap with the display panel and the back plate, making it easier for charges to be transferred to the display panel and affect the display effect. Based on the research on the above problems, the inventors provide a display module and display device to improve the anti-static capability of the display module and reduce the adverse effects of static electricity on the display effect.

[0034] To better understand this application, the following will be combined with... Figures 1 to 18 The display module and display device according to embodiments of this application will be described in detail.

[0035] Please see Figures 1 to 3This application provides a display module 1, including a display area AA and an edge area NA surrounding the display area AA. The edge area NA includes a flat area NA1 and a corner area NA2. The display module 1 includes multiple layers of film 11 stacked together, a first shielding portion 12, and a second shielding portion 13. The first shielding portion 12 is disposed between at least a portion of the film layers 11, and is located at least in the corner area NA2. The second shielding portion 13 is disposed on the periphery of at least a portion of the flat area NA1 and is in contact with at least a portion of the film layers 11. Both the first shielding portion 12 and the second shielding portion 13 are grounded.

[0036] like Figure 3 As shown, the display module 1 provided in this application includes a multilayer film layer 11 stacked together. The multilayer film layer 11 includes part or all of the following: cover plate 18, optical adhesive 24, polarizer 21, touch layer 15, display panel 14, back plate 22, SCF (Super Clean Foam) composite film 23 and electrostatic shielding layer 17.

[0037] The display module 1 of the display device 2 provided in this application includes a first shielding portion 12 and a second shielding portion 13. The first shielding portion 12 is disposed between at least a portion of the film layers 11, and the first shielding portion 12 is located at least in the corner region NA2. The first shielding portion 12 can be patterned according to the shape of the corner region NA2 to achieve good electrostatic shielding of the corner region NA2. The second shielding portion 13 is located on the periphery of at least a portion of the flat region NA1, and the second shielding portion 13 is in good contact with the periphery of the flat region NA1 to achieve electrostatic shielding of the flat region NA1. In the display module 1 provided in this application, the flat area NA1 and the corner area NA2 have different shapes, resulting in different manufacturing process difficulties. Different electrostatic shielding methods can be used for the flat area NA1 and the corner area NA2 respectively. That is, a first shielding part 12 is provided in the corner area NA2 to electrostatically shield the corner area NA2, which can ensure the manufacturing yield of the first shielding part 12 while meeting the process requirements. A second shielding part 13 is provided on the periphery of at least a part of the flat area NA1 to electrostatically shield the flat area NA1, so that all areas around the display panel 14 can be subjected to good electrostatic shielding effect.

[0038] In the above embodiments, the first shielding part 12 can be a metal layer or a conductive layer of other materials, and the second shielding part 13 can be a conductive adhesive. The conductive adhesive is prepared by a coating process. Due to the influence of the process, it is difficult to coat the conductive adhesive in the corner area NA2 of the display device 2, making it difficult for the conductive adhesive to make good contact with the part of the multilayer film layer 11 located in the corner area NA2. This results in poor electrostatic shielding effect at the poor contact location. Therefore, a first conductive part is set in this area. The first conductive part is located between at least a portion of the multilayer film layer 11, resulting in a higher preparation yield and ensuring the electrostatic shielding effect of the corner area NA2. At the same time, since the impedance of the conductive adhesive can be adjusted, the impedance can be adjusted according to the influence of the overall radio frequency signal of the display module 1 to achieve a better electrostatic shielding effect. Moreover, the preparation yield of the conductive adhesive is high in the flat area NA1. Therefore, selecting conductive adhesive in the flat area NA1 can further improve the electrostatic shielding effect of the flat area NA1.

[0039] In the above embodiments, the material of the second shielding part 13 can be conductive adhesive, which includes a colloid and conductive particles distributed within the colloid. This makes the conductive adhesive sticky and conductive, so as to facilitate contact and fixation with at least a portion of the periphery of the flat region NA1 of the multilayer film layer 11, while utilizing its conductivity to conduct away static electricity, thereby achieving electrostatic shielding.

[0040] In one feasible implementation, such as Figure 4 As shown, the flat area NA1 includes a preset shielding area NA11. The orthographic projection of the first shielding part 12 in the thickness direction of the display module 1 covers the preset shielding area NA11. The second shielding part 13 does not overlap with the edge of the preset shielding area NA11.

[0041] Display module 1 may include a cover plate 18, a display panel 14, and an electrostatic shielding layer 17, etc. The electrostatic shielding layer 17 is located on the side of the display panel 14 away from the cover plate 18. The electrostatic shielding layer 17 is generally made of copper foil. The main function of the electrostatic shielding layer 17 is to shield external electric fields. The electrostatic shielding layer 17 is grounded. During the manufacturing process of display module 1, a protective film 25 is set on one side surface of the electrostatic shielding layer 17. The protective film protects the electrostatic shielding layer 17 and prevents damage during the assembly of the electrostatic shielding layer 17 with the display panel 14, etc. The protective film is not removed during its own assembly process, but only during the assembly of the whole machine. It cannot be removed before the manufacturing of the second shielding part 13 is completed. The protective film includes a protrusion 251 to facilitate the adhesion and removal of the protective film to the electrostatic shielding layer 17. The protrusion of the protective film extends beyond the edge of the electrostatic shielding layer 17 and also extends beyond the edge of the display module 1. The protrusion is generally positioned opposite to the flat area NA1, so the protrusion will block the manufacturing of the second shielding part 13.

[0042] In the above embodiments of this application, the flat area NA1 includes a preset shielding area NA11. The preset shielding area NA11 can be a position within the flat area NA1 opposite to the protective film protrusion during the manufacturing process of the display module 1. The "opposite" refers to the fact that the outer edge of the preset shielding area NA11 and the edge of the protrusion facing the center of the display module 1 are projected onto the thickness direction of the display module 1. By setting the preset shielding area NA11 within the flat area NA1, and setting the first shielding part 12 within the preset shielding area NA11, and the orthogonal projection of the first shielding part 12 within the preset shielding area NA11 covering the preset shielding area NA11, the fabrication of the first shielding part 12 is not affected by the obstruction of the protrusion, thereby electrostatic shielding of the preset shielding area NA11 can be achieved through the first shielding part 12. The second shielding part 13 may not be provided on the periphery of the preset shielding area NA11, that is, the second shielding part 13 does not overlap with the edge of the preset shielding area NA11, in order to save materials.

[0043] In one feasible implementation, such as Figure 5 and Figure 6 As shown, the first shielding part 12 includes a first part 121 and a second part 122. The first part 121 is located in the corner region NA2. The first part 121 includes a first end 1211 and a second end 1212 arranged along its own extension direction. The first end 1211 is connected to one of the second parts 122, and the second end 1212 is connected to another second part 122. The dimension D of the second part 122 along the extension direction of the straight region NA1 is greater than or equal to 20 micrometers.

[0044] In the above embodiment, the first shielding part 12 includes a first portion 121 and a second portion 122. The first portion 121 is located in the corner area NA2, and the two second portions 122 are respectively located in the straight areas NA1 on both sides of the corner area NA2. The two ends of the first portion 121 are respectively connected to the second portions 122, thereby ensuring that the first shielding part 12 provides a good shielding effect for the corner area NA2. At the same time, the first shielding part 12 extends to the straight areas NA1 on both sides of the corner area NA2, and can be well connected with the second shielding part 13 in the straight areas NA1, so as to prevent electrostatic shielding failure at the transition position of the first shielding part 12 and the second shielding part 13. Furthermore, it facilitates synchronous grounding of both, thereby simplifying the grounding process.

[0045] In the above embodiments, since the second shielding part 13 is difficult to manufacture and has a poor yield in the corner area, the second shielding part 13 can only contact the first shielding part 12 in the straight area to achieve connection with the first shielding part 12. Setting the dimension D of the second part 122 along the extension direction of the straight area NA1 to be greater than or equal to 20 micrometers can reserve sufficient space for the contact between the first shielding part 12 and the second shielding part 13, so as to further ensure the contact yield of the first shielding part 12 and the second shielding part 13, and prevent poor overlap with the first shielding part 12 due to the dimension of the second part 122 being too small along the extension direction of the straight area NA1.

[0046] In one feasible implementation, such as Figures 7 to 9 As shown, the display module 1 includes a display panel 14 and a touch layer 15. The display panel 14 includes an array substrate 141 and a light-emitting layer 142 disposed on the array substrate 141. The array substrate 141 includes multiple conductive layers. The touch layer 15 is disposed on the side of the light-emitting layer 142 away from the array substrate 141 and includes at least one touch metal layer. The first shielding portion 12 is disposed in the same layer as the at least one conductive layer, or the first shielding portion 12 is disposed in the same layer as the touch metal layer.

[0047] In the above embodiment, the display module 1 includes a display panel 14, which includes an array substrate 141 and a light-emitting layer 142. The light-emitting layer 142 is located on one side of the array substrate 141. The array substrate 141 includes multiple conductive layers. Specifically, it may include a first metal layer 1411, a second metal layer 1412, a third metal layer 1413, and a fourth metal layer 1414 that are stacked and insulated from each other. The array substrate 141 includes transistors and capacitors. The first metal layer 1411 is used to form the gate and the lower electrode of the capacitor. The second metal layer 1412 is used to form the upper electrode of the capacitor. The third metal layer 1413 is used to form the source and drain of the transistor. The fourth metal layer 1414 is used to form signal lines, etc. The first shielding portion 12 may be formed in any one of the first metal layer 1411, the second metal layer 1412, the third metal layer 1413, and the fourth metal layer 1414. To improve light transmittance, a transparent conductive material is typically used at the position opposite the photosensitive module in the display module 1. The multilayer conductive layer may also include a transparent conductive layer, and the first shielding portion 12 can be formed on the aforementioned transparent conductive layer. The active layer 1416 of the transistor can be made of polysilicon or oxide semiconductor material, and the first shielding portion 12 can also be formed on the active layer. For example... Figure 8 As shown, the first shielding portion 12 may be formed on the fourth metal layer 1414. For example... Figure 9 As shown, the first shielding portion 12 may be formed on the third metal layer 1413.

[0048] like Figure 10 and Figure 11As shown, the display module 1 may further include a touch layer 15, which is formed on the side of the light-emitting layer 142 facing away from the array substrate 141. The touch layer 15 includes a first touch metal layer 151 and a second touch metal layer 152 for touch electrodes and touch traces. The first touch metal layer 151 and the second touch metal layer 152 are insulated from each other. The first shielding portion 12 may be formed in either the first touch metal layer 151 or the second touch metal layer 152. Figure 10 As shown, the first shielding portion 12 may be formed on the first touch metal layer 151. For example... Figure 11 As shown, the first shielding portion 12 may be formed on the second touch metal layer 152.

[0049] In the above embodiments, the first shielding part 12 is formed in the multilayer conductive layer or the touch metal layer, which can simplify the manufacturing process and does not increase the number of film layers 11 in the display module 1, thus helping to achieve the thinning of the display module 1.

[0050] In the above embodiments, the width d of the first shielding part 12 is greater than 10 micrometers to achieve its own good electrostatic shielding effect, while taking into account the space and manufacturing process limitations within the display module 1.

[0051] In one feasible implementation, such as Figure 12 As shown, the display module 1 includes a flexible circuit board 16, which includes a ground terminal 1611. The first shielding part 12 is electrically connected to the ground terminal 1611 through a first grounding wire 1415.

[0052] In the above embodiment, since the first conductive part is formed in the array substrate 141 or the touch layer 15, its grounding method can be adopted in the manner of synchronous grounding with the array substrate 141 and the touch layer 15, which helps to simplify the manufacturing process and simplify the wiring in the display module 1.

[0053] Specifically, the display module 1 includes a flexible circuit board 16, which is connected to the display panel 14. A grounding terminal 1611 is provided on the flexible circuit board 16. A first grounding wire 1415 is provided on the periphery inside the display panel 14. The first grounding wire 1415 is connected to the grounding terminal 1611. The touch layer 15 can also be grounded by connecting to the first grounding wire 1415.

[0054] The first grounding wire 1415 may be located in the first metal layer 1411, the second metal layer 1412, the third metal layer 1413, or the fourth metal layer 1414. For example... Figure 13 As shown, when the first shielding part 12 and the first grounding wire 1415 are arranged on the same layer, they can be directly connected to form an integrated structure, or, as... Figure 14As shown, the first shielding part 12 is connected to the connecting wire, and the first grounding wire 1415 is connected to the connecting wire through vias. Figure 15 As shown, when the first shielding part 12 and the first grounding wire 1415 are disposed in different layers, they can be directly connected through a via, and this application does not impose any special limitations.

[0055] In one feasible implementation, such as Figure 7 As shown, the multilayer film layer 11 in the display module 1 also includes an electrostatic shielding layer 17 disposed on the side of the display panel 14 away from the light-emitting surface, and the second shielding part 13 is electrically connected to the electrostatic shielding layer 17.

[0056] In the above embodiment, the grounding method of the second shielding part 13 can be achieved by direct contact with the electrostatic shielding layer 17. Specifically, during the preparation of the second shielding part 13, the second shielding part 13 can be extended to the periphery of the electrostatic shielding layer 17 to achieve good contact with the electrostatic shielding layer 17 and grounding.

[0057] In one feasible implementation, such as Figure 5 As shown, the first shielding part 12 extends into a portion of the flat region NA1 and contacts the second shielding part 13.

[0058] In the above embodiment, the side of the portion of the first shielding part 12 extending into the flat area NA1 contacts the second shielding part 13, thereby achieving an electrical connection between the first shielding part 12 and the second shielding part 13. This enables synchronous grounding of the first shielding part 12 and the second shielding part 13, simplifying the grounding process. Synchronous grounding of the first shielding part 12 and the second shielding part 13 can be achieved by connecting the first shielding part 12 to the grounding terminal 1611 of the flexible circuit board 16, or by electrically connecting the second shielding part 13 to the electrostatic shielding layer 17. The specific synchronous grounding process can be selected according to the actual situation of the display module 1, and this application does not impose any particular limitation.

[0059] In one feasible implementation, such as Figure 16 As shown, the edge of the first shielding part 12 includes protrusions 123 and recesses 124 spaced apart, and the second shielding part 12 is partially located within the recesses 124.

[0060] In the above embodiment, the edge of the first shielding part 12 includes a protrusion 123 and a recess 124, thereby increasing the effective length of the contact between the edge and the second shielding part 13, thus increasing the contact area between the first shielding part 12 and the second shielding part 13, and making the contact effect between the first shielding part 12 and the second shielding part 13 better. On the one hand, it can make the physical connection effect between the first shielding part 12 and the second shielding part 13 better, and make the grounding effect better when they are grounded simultaneously. On the other hand, it can make the transition of electrostatic shielding between the first shielding part 12 and the second shielding part 13 better, ensuring the electrostatic shielding effect of the first shielding part 12 and the second shielding part 13 on the entire circumference of the display module 1 after they are used together.

[0061] In one feasible implementation, such as Figure 17 As shown, the display module 1 also includes a cover plate 18 and a display panel 14. The cover plate 18 is disposed on the side of the display panel 14 facing the light-emitting surface and includes an extension 181 extending out of the display panel 14. The second shielding part 13 is connected to the side of the extension 181 facing the display panel 14.

[0062] The multilayer film layer 11 of the display module 1 also includes a cover plate 18, which includes an extension 181. The orthographic projection of the extension 181 on the display panel 14 does not overlap with the display panel 14. The side of the extension 181 facing the display panel 14 is in direct contact with the second shielding part 13. The second shielding part 13 is connected to the cover plate 18 to better conduct static electricity away from the cover plate 18.

[0063] In one feasible implementation, such as Figure 17 As shown, the first shielding part 12 is located on the side of the extension 181 facing the display panel 14, and part of the first shielding part 12 is located in the flat area NA1 and part of the corner area NA2. The second shielding part 13 is in contact with the part of the first shielding part 12 located in the flat area NA1. The display module 1 also includes an electrostatic shielding layer 17 disposed on the side of the display panel 14 away from the light-emitting surface, and the second shielding part 13 is electrically connected to the electrostatic shielding layer 17.

[0064] In the above embodiment, the first shielding part 12 is located on the side of the extension 181 facing the display panel 14, and part of it is located in the flat area NA1 and part of it is located in the corner area NA2. At this time, the corner area NA2 of the display module 1 can be electrostatically shielded by the first shielding part 12, and the flat area NA1 of the display module 1 can be electrostatically shielded by the second shielding part 13. At the same time, the edge of the part of the first shielding part 12 located in the flat area NA1 is in contact with the edge of the first shielding part 12, so that the first shielding part 12 can be electrically connected to the electrostatic shielding layer 17 through the second shielding part 13, so as to realize the synchronous grounding of the first shielding part 12 and the second shielding part 13.

[0065] In one feasible implementation, the first shielding part 12 is made of metal or conductive cloth.

[0066] In the above embodiments, when the first shielding part 12 is disposed on the cover plate 18, the first shielding part 12 can be disposed inside the cover plate 18, and the material can be metal, that is, the cover plate 18 can be a cover plate 18 with the first shielding part 12. Alternatively, the material of the first shielding part 12 can be conductive cloth, which can be attached to the side of the extension 181 facing the display panel 14 during module assembly or before module assembly, and is located in the corner area NA2. The manufacturing process of using conductive cloth is simpler and less expensive.

[0067] In one feasible implementation, such as Figure 17 As shown, it also includes a middle frame 19 and a middle frame sealant 20. The middle frame 19 is disposed on the periphery of the edge area NA of the display panel 14, and the middle frame sealant 20 is disposed between the second shielding part 13 and the middle frame 19 and between the middle frame 19 and the extension part 181.

[0068] In display module 1, the mid-frame sealant 20 is used to connect the mid-frame 19 and the extension 181 of the cover plate 18. However, with the demand for narrow bezels in display devices, the thickness of the mid-frame 19 has become narrower. When connecting the mid-frame 19 and the cover plate 18, the mid-frame sealant 20 overflows into the gap between the mid-frame 19 and the extension 181, extending to the periphery of the multilayer film layer 11 and contacting it. This can conduct static electricity from the cover plate 18 to the display panel 14, causing display abnormalities around the display panel 14. In this application, by providing a second shielding part 13, the overflowing mid-frame sealant 20 can be prevented from contacting the periphery of the multilayer film layer 11, so that the mid-frame sealant 20 is only located between the mid-frame 19 and the second shielding part 13 and between the extension 181 and the mid-frame 19, thereby reducing the probability of the mid-frame sealant 20 contacting the periphery of the multilayer film layer 11 and reducing the chance of display defects.
