DETAILED DESCRIPTION

[0041] The embodiments of the present application will be described in further detail below with reference to the drawings and examples. The detailed description and drawings of the following examples are used to exemplarily illustrate the principles of the present application, but cannot be used to limit the scope of the present application, i.e., the present application is not limited to the described examples.

[0042] In the description of the present application, it should be noted that, unless otherwise specified, the meaning of "a plurality of" is more than two; the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer" and the like merely facilitates the description of the present application and simplifies the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third" and the like are only for descriptive purposes and cannot be understood as indicating or implying relative importance. "Vertical" is not strictly vertical, but within the allowable range of error. "Parallel" is not strictly parallel, but within the allowable range of error.

[0043] In the present application, the mention of "embodiments" means that the specific features, structures or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The appearance of this phrase at various places in the specification does not necessarily mean the same embodiment, nor is it an independent or alternative embodiment to other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in the present application can be combined with other embodiments.

[0044] The orientation words appearing in the following description are the directions shown in the drawings, and are not a limitation on the specific structure of the present application. In the description of the present application, it should also be noted that, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0045] The existing display module includes a display panel and a cover plate. A large amount of electric charges are generated on the cover plate during use or testing. For example, in daily life, users have a high frequency of touch demand for the display module. When used intensively, the human body often rubs the surface of the cover plate for a long time, so that the cover plate has static charges. In addition, during the testing of the display module, a copper rod is used to rub the cover plate to test the touch function. A large amount of electric charges are generated during the process, and the large amount of electric charges form static electricity accumulation. The static electricity generated on the surface of the cover plate is easy to accumulate on both sides of the cover plate and is conducted to the back of the display panel through a certain path, causing the change of TFT (Thin Film Transistor) characteristics, and then the phenomenon of green display panel and uneven brightness occurs.

[0046] To solve the above problems, embodiments of the present application provide a display module and a display device. Each embodiment of the display module and the display device will be described below with reference to the accompanying drawings.

[0047] Embodiments of the present application provide a display module. The display module can be an organic light emitting diode (OLED) display module. The display module can also be other types of display modules, such as a micro light emitting diode (Micro-LED) or a quantum dot light emitting diode (QLED) display module.

[0048] Please refer to Figure 1 , Figure 1 A cross-sectional schematic view of the display module provided by the embodiments of the present application is shown. The display module 100 includes a display panel 10, a cover plate 20, an electrostatic discharge layer 30, and an insulating shielding layer 40. The cover plate 20 is arranged on one side of the display panel 10. The electrostatic discharge layer 30 includes a first discharge part 31 and a second discharge part 32 connected to each other. The first discharge part 31 is arranged on the side of the display panel 10 away from the cover plate 20. The second discharge part 32 is arranged around the circumferential side of the display panel 10, and one end of the second discharge part 32 away from the first discharge part 31 is connected to the cover plate 20. The insulating shielding layer 40 is arranged between the electrostatic discharge layer 30 and the display panel 10.

[0049] The cover plate 20 is used to protect the display panel 10, wherein the cover plate 20 can be a glass cover plate 20, or other transparent materials, and the embodiments of the present application are not limited to this. The display panel 10 can be a flexible display panel or a rigid display panel. The static electricity release layer 30 is a conductive layer, for example, a metal layer, and static electricity accumulated at the edge of the cover plate 20 can be transmitted to the second release part 32, or transmitted to the first release part 31 through the second release part 32, so as to realize the release of static electricity. The material of the static electricity release layer 30 can be a conductive metal such as silver, copper, aluminum and its alloy, which has good conductivity, eliminates static electricity of the display module 100, and also has good heat dissipation effect. The first release part 31 and the second release part 32 can be made of the same material and integrally formed, which is convenient for process preparation and improves production efficiency. For example, the first release part 31 and the second release part 32 can be integrally formed copper foil. The static electricity release layer 30 can be an integrally formed structure. The static electricity release layer 30 can be grounded.

[0050] It should be noted that the first release part 31 is arranged on the side of the display panel 10 away from the cover plate 20, which can be that the first release part 31 covers the whole side of the display panel 10 away from the cover plate 20, or partially covers the side of the display panel 10 away from the cover plate 20, as long as the first release part 31 and the second release part 32 are connected. The second release part 32 is arranged around the periphery of the display panel 10, which can be that the second release part 32 covers the whole periphery of the display panel 10, or partially covers the periphery of the display panel 10, for example, the second release part 32 is connected to the cover plate 20 in a segmented manner along the periphery of the display panel 10, that is, the second release part 32 has a gap along the periphery of the display panel 10, as long as the second release part 32 is present on the periphery of the display panel 10. The second release part 32 is connected to the cover plate 20, which can be that the second release part 32 directly contacts the cover plate 20, or the second release part 32 is connected to the cover plate 20 through other conductive medium, as long as the static electricity on the cover plate 20 can be conducted to the second release part 32. The connection mode of the second release part 32 and the cover plate 20 can be set by the person skilled in the art according to the actual needs.

[0051] Optionally, the resistance value of the insulating shielding layer 40 is greater than or equal to 10 14 Ω. The insulating shielding layer 40 can be made of insulating high-impedance material to improve the anti-static ability of the insulating shielding layer 40, and further prevent charges from entering the array layer 12 from the side of the substrate 11. Optionally, the resistance value of the insulating shielding layer 40 is less than or equal to 10 17 Ω. The insulating shielding layer 40 is made of high-impedance material, and the resistance value can be set to 10 14 ~10 17The insulating shielding layer 40 is attached to the display panel 10 to block the conduction of static charge into the display panel 10. The insulating shielding layer 40 and the electrostatic discharge layer 30 may have the same shape and be positioned identically, for example, their projections on the display module 100 may be exactly the same. Alternatively, the insulating shielding layer 40 and the electrostatic discharge layer 30 may differ; for example, the insulating shielding layer 40 may completely cover the periphery of the display panel 10 and the side facing away from the cover plate 20, while the electrostatic discharge layer 30 may not completely cover it, meaning the projected area of ​​the electrostatic discharge layer 30 on the display module 100 is smaller than the projected area of ​​the insulating shielding layer 40 on the display module 100.

[0052] In this embodiment, the static electricity accumulated on the cover plate 20 can be released through the static discharge layer 30. Since the first discharge portion 31 is located on the side of the display panel 10 away from the cover plate 20, and the second discharge portion 32 is arranged around the periphery of the display panel 10, the display panel 10 is effectively enclosed, enabling rapid static electricity release. Furthermore, an insulating shielding layer 40 is provided between the static discharge layer 30 and the display panel 10. This prevents static charges from passing through the insulating shielding layer 40 and affecting the performance of the display panel 10, and isolates any static electricity that may accumulate around and on the back of the static discharge layer 30, thus preventing the display panel 10 from exhibiting a greenish tint or uneven brightness.

[0053] Figure 2 This is a top view schematic diagram of a second release part of a display module provided in an embodiment of this application, as shown below. Figure 2 As shown, the second release section 32 includes multiple release segments 321 (e.g., 3 or 5 segments), which are arranged at intervals along the periphery of the display panel 10. It is understood that both ends of each release segment 321 are connected to the cover plate 20 and the first release section 31, respectively, to ensure charge transfer. Since the second release section 32 is made of metal, it easily shields antenna signals. Therefore, arranging multiple release segments 321 at intervals along the periphery of the display panel 10, compared to completely covering the periphery of the display panel with the second release section, creates a blank area that is left untreated, thus avoiding interference with the reception and / or transmission of antenna signals by the display module 100. The display module may also include an antenna structure located on the side of the electrostatic discharge layer 30 and the insulating shielding layer 40 closest to the display panel 10. The antenna structure may be disposed within the display panel 10.

[0054] Optionally, the first release section 31 can cover the entire side of the display panel 10 away from the cover plate 20 to ensure that the static electricity on the back of the display module 100 is more easily released and to improve the charge release capability of the static electricity release layer 30.

[0055] Figure 3 Another cross-sectional view of the display module provided in the embodiments of this application is shown below. Figure 3As shown, the display module 100 further comprises a charge conduction layer 33, and the second release part 32 is connected to the cover plate 20 through the charge conduction layer 33. Specifically, a dense charge conduction layer 33 can be formed on the side of the cover plate 20 facing the display panel 10 by applying conductive material or sputtering metal, so as to reduce the contact resistance between the static electricity release layer 30 and the cover plate 20. In addition to the conductive material, the charge conduction layer 33 can also be doped with colloidal material, so that the charge conduction layer 33 has viscosity, and the connection firmness between the second release part 32 and the cover plate 20 is increased.

[0056] Optionally, if the charge conduction layer 33 has no viscosity or small viscosity, such as Figure 4 As shown, Figure 4 Another cross-sectional view of the display module provided by the embodiment of the present application is shown, and the display module 100 further comprises a first adhesive layer 34, and the second release part 32 is pasted to the charge conduction layer 33 through the first adhesive layer 34. The first adhesive layer 34 can be a conductive adhesive layer. The first adhesive layer 34 can be a solid adhesive doped with conductive particles such as carbon black, graphite, high-density silver, low-density silver, and copper-plated silver, which can not only adhere the second release part 32 to the charge conduction layer 33, but also transmit charges. Of course, in other embodiments, the second release part 32 can also be directly adhered to the cover plate 20 through the first adhesive layer 34.

[0057] If the first adhesive layer 34 is between the second release part 32 and the cover plate 20, and the second release part 32 is arranged in multiple sections, and the multiple release sections 321 are arranged along the periphery of the display panel 10, the first adhesive layer 34 is also arranged in multiple sections corresponding to the second release part 32.

[0058] Optionally, as shown, Figure 5 As shown, Figure 5 A top view of a charge conduction layer of the display module provided by the embodiment of the present application is shown, and the charge conduction layer 33 is arranged in a ring shape close to the edge of the cover plate 20, so as to improve the charge conduction ability of the charge conduction layer 33. Of course, in other embodiments, the charge conduction layer 33 can also be arranged in sections along the edge of the cover plate 20.

[0059] In some embodiments, the resistivity of the charge conduction layer 33 is greater than or equal to 10 -10 Ω·cm. The charge conduction layer 33 has low resistivity and high conductivity, which can improve the charge conduction ability. Optionally, the resistivity of the charge conduction layer 33 is less than or equal to 10 2 Ω·cm.

[0060] Figure 6 A partial cross-sectional view of the display module provided by the embodiment of the present application is shown, and the display module 100 further comprises a first adhesive layer 34, and the second release part 32 is pasted to the charge conduction layer 33 through the first adhesive layer 34. The first adhesive layer 34 can be a conductive adhesive layer. The first adhesive layer 34 can be a solid adhesive doped with conductive particles such as carbon black, graphite, high-density silver, low-density silver, and copper-plated silver, which can not only adhere the second release part 32 to the charge conduction layer 33, but also transmit charges. Of course, in other embodiments, the second release part 32 can also be directly adhered to the cover plate 20 through the first adhesive layer 34. Figure 6As shown, the display module 100 has a display area AA and a non-display area NA arranged around the display area AA. The display area AA can emit light by arranging a plurality of sub-pixels in an array to realize image display. The non-display area NA arranged around the display area AA is used to arrange a driving circuit and can also be used to arrange a driving chip to drive the sub-pixels of the display area AA. The non-display area NA can also be used to arrange connection traces to connect the sub-pixels of the display area AA to the driving chip. The second release portion 32, the charge conduction layer 33, and the first adhesive layer 34 of the present embodiment are arranged in the non-display area NA, which can avoid affecting the display of the display module 100.

[0061] The display module 100 further includes a light shielding layer 21 arranged on the side of the cover plate 20 facing the display panel 10. The light shielding layer 21 covers the non-display area NA, and the second release portion 32 is arranged on the side of the light shielding layer 21 facing away from the cover plate 20. The light shielding layer 21 can be made of ink, such as black ink, which not only has the function of shielding light but also can shield the components such as the driving circuit, the driving chip, and the connection traces in the non-display area NA to play a decorative role and improve the aesthetics of the display module 100.

[0062] In another embodiment, the charge conduction layer 33 is arranged on the side of the light shielding layer 21 facing away from the cover plate 20. In the direction along the non-display area NA pointing to the display area AA, the width D1 of the charge conduction layer 33 is smaller than the width D2 of the light shielding layer 21, so that the charge conduction layer 33 is spaced apart from the display area AA by a certain gap to avoid the slurry flowing into the display area AA when the charge conduction layer 33 is prepared, thereby affecting the display effect of the display area AA.

[0063] Optionally, the light shielding layer 21 is a conductive light shielding layer 21, that is, the light shielding layer 21 is doped with conductive particles, such as conductive ink. On the one hand, the conductive light shielding layer 21 has conductive properties, which can ensure that the conductive light shielding layer 21 serves as part of the static electricity dissipation path to conduct static electricity out. On the other hand, the conductive light shielding layer 21 can shield components such as the driving circuit and the connection traces in the display module 100 to play a decorative role and improve the aesthetics of the display module 100. The light shielding layer 21 and the charge conduction layer 33 can be combined into one.

[0064] In some embodiments, as shown in Figure 3 The insulating shielding layer 40 includes a first shielding portion 41 arranged between the first release portion 31 and the display panel 10. The first shielding portion 41 is integrally attached to the side of the display panel 10 facing away from the cover plate 20 to improve the charge shielding performance of the side of the display panel 10 facing away from the cover plate 20.

[0065] Optionally, the insulating shielding layer 40 further comprises a second shielding portion 42, the second shielding portion 42 is arranged around the periphery of the display panel 10, and the second shielding portion 42 is arranged between the second releasing portion 32 and the display panel 10. The second shielding portion 42 is attached to the periphery of the display panel 10, and the periphery of the display panel 10 is completely wrapped, which effectively prevents the charge from entering the display panel 10 from the side, thereby affecting the performance of the display panel 10.

[0066] Figure 7 Another cross-sectional view of the display module is provided in the embodiments of the present application, as shown in FIG. 6, the display module 100 further comprises an optical adhesive layer 16 between the cover plate 20 and the display panel 10, and the second shielding portion 42 is connected to the first shielding portion 41 at the end away from the cover plate 20, and the end of the second shielding portion 42 close to the cover plate 20 at least extends to the optical adhesive layer 16. Figure 7

[0067] The optical adhesive is colorless and transparent, with a light transmittance of more than 90%, good cementing strength, and can be cured at room temperature or medium temperature, and has the specific feature of small curing shrinkage. In the embodiments, the second shielding portion 42 is extended to the optical adhesive pasted with the cover plate, so that the side of the display panel 10 has the insulating shielding layer 40 from top to bottom, and the effect of insulating shielding is improved. The optical adhesive layer 16 can be insulating, so as to form a closed space with the insulating shielding layer 40, so as to prevent the static charge from affecting the performance of the display panel through the insulating shielding layer and the optical adhesive layer 16. The optical adhesive layer 16 can be conductive, and the optical adhesive layer 16 can be connected with the second releasing portion 32 and / or the charge conduction layer 33, so as to guide the static charge to the first releasing portion 31.

[0068] Optionally, the display module 100 further comprises a polarizer 15, and the polarizer 15 is located between the optical adhesive layer 16 and the cover plate 20. The polarizer 15 is pasted on the side of the cover plate 20 facing the display panel 10 through the optical adhesive layer 16.

[0069] In some embodiments, the insulating shielding layer 40 contains a light shielding material to shield the display panel 10. The insulating shielding layer 40 can be a photosensitive resin composition with high impedance and good water resistance. The insulating shielding layer 40 can use the material of the black matrix of the liquid crystal display (LCD) display panel 10. The black matrix is mainly used for light shielding between red (R), green (G), and blue (B) pixels in the liquid crystal display to avoid color mixing between RGB, and has good light shielding effect. The first shielding portion 41 and the second shielding portion 42 can be made of the same material and integrally formed, which is convenient for process preparation and improves production efficiency. The insulating shielding layer 40 can be an integrally formed structure.

[0070] ​In some embodiments, the insulating shielding layer 40 and the electrostatic discharge layer 30 have the same shape towards the surface of the display panel 10. The insulating shielding layer 40 and the electrostatic discharge layer 30 can be located in the same composite structure, so as to simultaneously cut and pattern the insulating shielding layer 40 and the electrostatic discharge layer 30 in the composite structure, simplifying the process.

[0071] Specifically, the display panel 10 includes a substrate substrate 11, an array layer 12, a display layer 13 and an encapsulation layer 14 which are sequentially stacked, and the encapsulation layer 14 is close to the cover plate 20 relative to the substrate substrate 11. The display panel 10 can be a flexible display panel. The substrate substrate 11 can be a flexible substrate substrate, and the substrate substrate 11 can include a plurality of flexible film layers which are stacked; the flexible film layers can be made of polyimide (PI), polyethylene terephthalate (PET) or the like, so that the display panel 10 can be bent. The array layer 12 is generally composed of active layer, insulating layer, conductive layer and the like, and by patterning these film layers, a driving circuit for controlling the light-emitting layer to emit light can be formed, and the specific circuit structure has various implementation manners, which will not be described here. The display layer 13 is located away from the substrate substrate 11 on the side of the array layer 12, and the display layer 13 includes an anode layer, a light-emitting layer and a cathode layer, and the light-emitting layer further includes a light-emitting material layer, a hole transport layer and an electron transport layer. When the anode layer and the cathode layer are powered, electrons and holes migrate to the light-emitting material layer from the electron transport layer and the hole transport layer, respectively, and meet in the light-emitting material layer to form excitons to excite the light-emitting molecules, thereby generating visible light to achieve the purpose of display. The encapsulation layer 14 can be located away from the substrate substrate 11 on the side of the display layer 13 and cover the display layer 13, for protecting the display layer 13 from being eroded and damaged by water vapor and oxygen. The encapsulation layer 14 can be a thin film encapsulation layer, and can include a first inorganic encapsulation layer, an organic encapsulation layer and a second inorganic encapsulation layer which are stacked, so as to block water vapor and oxygen. A touch layer can be further provided between the encapsulation layer 14 / touch layer and the cover plate 20, so as to achieve the purpose of user touch. A polarizer 15, specifically a circular polarizer 15, can be further provided between the encapsulation layer 14 / touch layer and the cover plate 20, which can not only eliminate the reflection of the pixel electrode, but also eliminate the reflection of the touch screen electrode, and can be used to improve the contrast of the display module 100 in bright environment.
