These terms are used only to distinguish one element from another. For example, without departing from the scope of this application, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element. Words such as “comprising” or “including” mean that the element or object preceding the word covers the element or object listed following the word and its equivalents, without excluding other elements or objects.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0032] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0033] It is understandable that "at least one" refers to one or more, and "multiple" refers to two or more. "At least a part of an element" refers to part or all of an element.

[0034] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising / including” or “having,” etc., specify the presence of the stated features, wholes, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof. Meanwhile, the term “and / or” as used in this specification includes any and all combinations of the associated listed items.

[0035] In existing displays, in order to realize functions such as image acquisition, infrared proximity sensing, light sensing, and infrared remote control on the light-emitting side of the display, it is often necessary to drill holes in the display. Generally, the holes are drilled in the upper area of ​​the display. The more common notch screens and waterdrop screens are all types of punched displays. The image acquisition module, infrared sensing module, proximity sensing module, light sensing module, and remote control module are all set in the hole.

[0036] In practical applications, some software designs allow specific content to be displayed in the punch-hole area, which refers to the area on the display screen surrounding the hole. For example, prompts, system information, and notifications can be displayed in the punch-hole area, thus creating a demand for touch control of this area. Besides this, users may touch the punch-hole area for other reasons during screen use, such as due to habit or accidental touches.

[0037] However, after long-term research, the inventors discovered that users touching the perforated area can easily cause the perforated area to turn green or produce bright spots, which will seriously affect the display effect of the screen.

[0038] In view of this, embodiments of this application provide a display module and a display device, wherein the display module has a display area and a border area at least partially surrounding the display area, the display module includes multiple functional film layers and a cover plate disposed on one side of the multiple functional film layers, wherein the multiple functional film layers include an optically transparent adhesive layer, a polarizer, a display layer, a driving layer, a support film, SCF foam, and an SCF metal layer disposed sequentially; wherein the optically transparent adhesive layer is used to bond the cover plate, the polarizer is used to control the polarization direction of light, the display layer includes multiple light-emitting units, specifically, the multiple light-emitting units may include at least one first light-emitting unit, at least one second light-emitting unit, and at least one third light-emitting unit, the first light-emitting unit, the second light-emitting unit, and the third light-emitting unit are used to emit light of different colors, the driving layer is used to drive the multiple light-emitting units, and the support film and SCF foam are used to provide... The display module includes mechanical support or cushioning, grounding of the SCF metal layer, and a through-hole extending along the thickness direction of the multiple functional film layers. A conductive layer is coated on the side of the cover plate facing the multiple functional film layers, and this conductive layer contacts the through-hole to conduct static electricity generated at the edge of the through-hole to ground. Normally, user touches on the perforated area generate static electricity at the boundary of the perforated area, i.e., at the edge of the through-hole. The accumulation of static electricity can cause the perforated area to turn green or produce bright spots. In the display module provided in this application, a conductive layer is coated on the side of the cover plate facing the multiple functional film layers, and this conductive layer contacts the through-hole. This allows the static electricity generated at the edge of the through-hole to be conducted to ground, thus discharging static electricity generated by user touches and preventing static accumulation. This, to a certain extent, avoids the phenomenon of greening or bright spots in the perforated area.

[0039] The following description, in conjunction with the accompanying drawings, will exemplarily illustrate the display module and display device provided in this application. It is understood that the following embodiments are merely illustrative examples, but the display module provided in this application is not limited thereto and can also be applied to and protected in similar structures.

[0040] Please refer to Figure 1The illustration shows a cross-sectional view of a display module provided in an embodiment of this application. It should be noted that the display module provided in this embodiment can be an Organic Light-Emitting Diode (OLED) display module, a Micro Organic Light-Emitting Diode (Micro OLED) display module, a Light Emitting Diode (LED) display module, a Quantum Dot Light Emitting Diode (QLED) display module, a Mini Light Emitting Diode (MiniLED) display module, a Micro Light Emitting Diode (Micro LED) display module, or a Liquid Crystal Display (LCD) display module, etc. This embodiment uses an OLED display module as an example for illustration.

[0041] like Figure 1 As shown, the display module includes CG (Cover Glass), OCA (Optically Clear Adhesive), POL (Polarizer), display layer, driving layer, support film, SCF (Soft Conductive Film) foam, and SCF metal layer.

[0042] The cover plate is the outermost protective layer of the display module, preventing the display module from being scratched or impacted. The cover plate is generally made of chemically strengthened glass. In actual implementation, the surface of the cover plate can be coated with anti-reflective coatings, oleophobic layers, etc.

[0043] Optical transparent adhesive is used to bond cover plates. In addition, it can reduce interface reflection and maintain high light transmittance. In practical applications, optical transparent adhesive can be a solid film, which is solvent-free and can avoid bubbles.

[0044] Polarizers are used to control the polarization direction of light and can be used in conjunction with the display layer to adjust brightness.

[0045] The display layer includes multiple light-emitting units, which can be arranged in an array. Each light-emitting unit may include an emission layer (EML). It may also include one or more of the following: a hole injection layer (HIL), a hole transport layer (HTL), an electron injection layer (EIL), an electron transport layer (ETL), a hole block layer (HBL), and an electron block layer (EBL). Alternatively, the light-emitting unit may be a stacked light-emitting structure, i.e., including at least two light-emitting layers and a charge generation layer (CGL) located between adjacent light-emitting layers. Multiple light-emitting units are used to emit light of different colors. For example, the multiple light-emitting units may include a first light-emitting unit emitting red light, a second light-emitting unit emitting green light, and a third light-emitting unit emitting blue light. For ease of understanding, this embodiment of the application will be described using this as an example.

[0046] The driving layer is used to drive the multiple light-emitting units. In practical applications, the driving layer may include a thin-film transistor array.

[0047] The support membrane and SCF foam are used to provide mechanical support or cushioning to prevent deformation or disperse pressure. The support membrane can be made of polyimide, metal foil, etc., and the SCF foam can be made of foam filled with conductive particles (such as carbon or metal), which has both flexibility and conductivity.

[0048] In addition to grounding the SCF metal layer, it can also enhance conductivity and / or provide a signal transmission path. In actual implementation, the SCF metal layer can be made of copper foil, aluminum foil or ITO (indium tin oxide) coating.

[0049] like Figure 1 As shown, when a user touches the perforated area, a negative charge is generated on the surface of the CG facing the light-emitting side. Correspondingly, an opposite induced charge, i.e., a positive charge, is generated on the other side of the CG at the boundary of the perforated area. This positive charge is introduced into the carbonization path of the laser-cut edge. Through this carbonization path, the positive charge is transferred to the support film. Thus, the display layer and the driving layer generate the opposite induced charge, i.e., a negative charge. This negative charge causes Vth to be negatively biased, resulting in a greenish tinge or the formation of a bright spot in the perforated area. In other words, the accumulation of static electricity at the boundary of the perforated area causes the perforated area to appear greenish or produce a bright spot.

[0050] To solve the above problems, please refer to Figure 2 It shows an exemplary schematic diagram of the display module provided in the embodiments of this application, such as... Figure 2 As shown, the display module has a display area AA (Active Area) and a border area NA (Non-Active Area) that is at least partially surrounding the display area AA.

[0051] The display area AA is the actual area used for display within the display module, where all pixels emit light or modulate light. The bezel area NA surrounds the display area AA and does not participate in the display; it is mainly used for functional integration and structural support. In practical applications, circuit wiring, such as driver ICs, signal traces (Gate Driver, Source Driver), and power lines, can be located in the bezel area NA. In addition, the bezel area NA also serves to support the display module and prevent edge warping.

[0052] The display module includes multiple functional film layers and a cover plate disposed on one side of these multiple functional film layers. Please refer to the reference. Figure 1 Optionally, the plurality of functional film layers may include an optically transparent adhesive layer, a polarizer, a display layer, a driving layer, a support film, SCF foam, and an SCF metal layer. It should be noted that the above is only an exemplary description of the plurality of functional film layers. In practical applications, the plurality of functional film layers may include more or fewer film layers than described above. For example, the plurality of functional film layers may also include a touch layer, an encapsulation layer, etc. Furthermore, the stacking order of the plurality of functional film layers may be [not specified in the original text]. Figure 1 The same as shown, or can be the same as Figure 1 As shown in the image, this application does not impose specific limitations on this matter.

[0053] like Figure 2 As shown, the display area AA includes through holes 201 extending along the thickness directions of multiple functional film layers. In other words, the through holes 201 penetrate the optically transparent adhesive layer, polarizer, display layer, driving layer, support film, SCF foam, and SCF metal layer. It should be noted that the through holes 201 do not penetrate the cover plate. In an optional embodiment of this application, "does not penetrate the cover plate" can be understood as: the hole structure of the through holes 201 does not penetrate the cover plate at all, or "does not penetrate the cover plate" can be understood as: the hole structure of the through holes 201 penetrates the cover plate, but does not penetrate the cover plate.

[0054] It should also be pointed out that, although Figure 2Only one through hole 201 is shown in the figure. However, in actual applications, the display area AA may include one or more through holes, which are all through the thickness directions of multiple functional film layers. When the display area AA includes multiple through holes 201, the multiple through holes 201 may be flush. Alternatively, all or part of the multiple through holes 201 may be interconnected. Alternatively, the multiple through holes 201 may be equally spaced. The spacing between the multiple through holes 201 can be determined according to design requirements. This application embodiment does not specifically limit this.

[0055] In an optional embodiment of this application, the through hole 201 can be disposed in the upper part of the display area AA. Furthermore, as described above, in an optional embodiment of this application, the through hole 201 can house components such as an image acquisition module, an infrared sensing module, a proximity sensing module, a light sensing module, and a remote control module. This application does not specifically limit the components disposed within the through hole 201.

[0056] It should be noted that when multiple through holes 201 are provided in the display area AA, the components provided in different through holes 201 may be the same or different, and this application embodiment does not specifically limit this.

[0057] Furthermore, the embodiments of this application do not limit the cross-sectional shape of the through hole 201. Generally, the cross-sectional shape of the through hole 201 can be circular, or of course, other shapes.

[0058] In an optional embodiment of this application, a conductive layer is coated on one side of the cover plate facing the plurality of functional film layers. As the name suggests, the conductive layer is a film layer with conductivity. This application embodiment does not limit the specific coating method of the conductive layer. The conductive layer is in contact with the through hole 201 so that the static electricity generated at the edge of the through hole 201 can be conducted to the ground through the conductive layer. In other words, the conductive layer is in electrical contact with the through hole 201 and the ground respectively.

[0059] It should be noted that the contact between the conductive layer and the via 201 refers to the electrical contact between the conductive layer and the boundary of the via 201. It should also be noted that if the display area AA includes multiple vias 201, the conductive layer should be in electrical contact with all of the vias. Furthermore, if the display area AA has multiple vias 201 that are interconnected, the conductive layer may only be in electrical contact with one of the vias 201.

[0060] The display module provided in this embodiment has a display area and a border area at least partially surrounding the display area. The display module includes multiple functional film layers and a cover plate disposed on one side of the multiple functional film layers. The multiple functional film layers include, sequentially arranged, an optically transparent adhesive layer, a polarizer, a display layer, a driving layer, a support film, SCF foam, and an SCF metal layer. The optically transparent adhesive layer is used to bond the cover plate; the polarizer is used to control the polarization direction of light; the display layer includes multiple light-emitting units, including at least one first light-emitting unit, at least one second light-emitting unit, and at least one third light-emitting unit, which emit light of different colors; the driving layer is used to drive the multiple light-emitting units; the support film and SCF foam provide mechanical support or cushioning; and the SCF metal layer... The display area includes through-holes extending along the thickness direction of the multiple functional film layers. A conductive layer is coated on the side of the cover plate facing the multiple functional film layers. This conductive layer contacts the through-holes, allowing static electricity generated at the edge of the through-holes to be conducted to ground. Normally, when a user touches the perforated area, static electricity is generated at the boundary of the perforated area, that is, at the edge of the through-hole. The accumulation of static electricity can cause the perforated area to turn green or produce bright spots. However, in the display module provided in this application, a conductive layer is coated on the side of the cover plate facing the multiple functional film layers. This conductive layer contacts the through-holes, allowing static electricity generated at the edge of the through-holes to be conducted to ground. This can discharge static electricity generated by user touch, preventing static electricity accumulation and thus avoiding the phenomenon of greening or bright spots in the perforated area to a certain extent.

[0061] Please refer to Figure 3 The diagram illustrates an alternative schematic of the cover plate. In one embodiment, a light-shielding layer 202 is coated on the side of the cover plate facing the plurality of functional film layers. The light-shielding layer 202 is located at least in the border area NA. In an alternative embodiment of this application, the light-shielding layer 202 may be aligned with the edge of the display area AA. In an alternative embodiment of this application, the light-shielding layer 202 may also be disposed around the through-hole 201.

[0062] The conductive layer is used to conduct static electricity generated at the edge of the through hole 201 to the light-shielding layer 202, and then conduct it to the ground via the conductive element.

[0063] Understandably, the main function of the light-shielding layer 202 located in the bezel area NA is to provide optical shielding, blocking the internal circuitry, wiring, adhesive materials, and other non-display components of the bezel area NA from being visible from the outside, thus preventing light leakage or visual noise. In addition, the light-shielding layer 202 can also improve contrast, reduce the reflection of ambient light in the bezel area NA, and enhance the purity of the content displayed in the display area AA. Furthermore, the light-shielding layer 202 can also serve as a physical barrier to prevent water, oxygen, and dust from entering the display module from the edges.

[0064] In actual implementation, the light-shielding layer 202 can be selected from black matrix (BM) material or composite functional material. For example, in an optional embodiment of this application, the material of the light-shielding layer 202 may include ink.

[0065] In optional embodiments of this application, the conductive element 203 may include at least one of the following: an antistatic liquid, a conductive adhesive, a wire, or a conductive cloth. Optionally, the antistatic liquid may include a surfactant and a conductive polymer. Optionally, the conductive adhesive may include an epoxy resin / silicone matrix and a silver / carbon nanotube filler. Optionally, the wire may include copper, gold wire, silver, or FPC (flexible printed circuit). Optionally, the conductive cloth may include polyester fiber and a nickel-plated or copper-plated coating.

[0066] Please refer to Figure 4 In one possible implementation, the conductive element 203 can be disposed below the light-shielding layer 202 located in the frame area NA to prevent the conductive element 203 from being visible from the outside. In addition, the conductive element 203 can be electrically connected to the SCF metal layer to ground.

[0067] In another possible implementation, the conductive element 203 can be disposed below the light-shielding layer 202 to prevent the conductive element 203 from being visible from the outside. In addition, the conductive element 203 can be electrically connected to the mid-frame of the display device to ground. The display module is disposed in the display device, which can be, for example, a mobile phone, tablet computer, digital camera, smart bracelet, smart glasses, etc.

[0068] In practical applications, the mid-frame of a display device is a key structural component connecting the display module, battery, motherboard, and other core components, undertaking multiple functions such as mechanical support, heat dissipation, electromagnetic shielding, and overall device integration. Generally, the mid-frame is made of metal, such as aluminum alloy, magnesium alloy, or stainless steel. Typically, the mid-frame is used to secure the display module using adhesive backing or snap-fit ​​structures.

[0069] In practical applications, user touches on the perforated area can easily cause the edges of the display screen to appear green or produce bright spots. This is because when a user touches the perforated area, a negative charge is generated on one side of the CG surface. Correspondingly, in addition to the opposite induced charge being generated at the boundary of the perforated area on the other side of the CG, an opposite induced charge, i.e., a positive charge, is also generated on the surface of the bezel area NA on the other side of the CG. This positive charge is also transferred to the support film, thereby generating the opposite induced charge, i.e., a negative charge, in the display layer and driving layer. This negative charge causes Vth to be negatively biased, resulting in the edges of the display screen appearing green or producing bright spots.

[0070] In the embodiments of this application, the static electricity generated at the edge of the through hole 201 is first conducted to the light-shielding layer 202 located in the frame area NA by the conductive layer. Then, the static electricity generated at the edge of the through hole 201 is conducted to the ground by the light-shielding layer 202 through the conductive element, for example, through the SCF metal layer or the middle frame of the display device. This allows the static electricity accumulated by the cover plate in the frame area NA to be discharged through the SCF metal layer or the middle frame of the display device, preventing the edge area of ​​the display screen from turning green or producing bright spots, thereby further improving the display effect.

[0071] In an optional embodiment of this application, the conductive layer may include a plurality of spaced conductive films, wherein the plurality of spaced conductive films are all in contact with the through hole 201 so that the static electricity generated at the edge of the through hole 201 can be conducted to ground through the plurality of conductive films.

[0072] In optional embodiments of this application, the spacing between the spaced conductive films may be equal or unequal, and the sizes of the spaced conductive films may be equal or unequal; this application does not specifically limit this. In optional embodiments of this application, the plurality of conductive films may be arranged in an array or in other arrangements; this application does not specifically limit this.

[0073] In addition, in optional embodiments of this application, two adjacent conductive films are electrically connected. For example, a conductive line can be provided between two adjacent conductive films, and the two adjacent conductive films can be electrically connected through the conductive line. Or, for example, the two adjacent conductive films can be electrically connected through an electrical connection structure on the two conductive films.

[0074] In an optional embodiment of this application, multiple electrostatic discharge paths can be formed by setting multiple spaced conductive films, so that the accumulated static electricity can be discharged through different electrostatic discharge paths, thereby ensuring the efficiency of electrostatic discharge, and further avoiding the occurrence of greening or bright spots, thereby further ensuring the display effect.

[0075] In optional embodiments of this application, the conductive layer can be made of a transparent material. For example, the conductive layer can be made of ITO (Indium Tin Oxide), metal mesh, silver nanowires, graphene, conductive polymers, etc. In optional embodiments of this application, the light transmittance of the conductive layer is greater than 90%; preferably, the light transmittance of the conductive layer is greater than 95%. Making the conductive layer a transparent material ensures that the brightness of the display area AA is not affected, thereby ensuring the display effect.

[0076] In optional embodiments of this application, the thickness of the conductive layer is between 100nm and 200nm, specifically 100nm, 120nm, 140nm, 160nm, 180nm, and 200nm. It should be noted that the 100nm to 200nm range in this embodiment includes both 100nm and 200nm endpoints. Setting the conductive layer to be thinner does not affect the overall thickness of the display module or subsequent bonding operations.

[0077] In an optional embodiment of this application, conductive adhesive can be coated on the wall of the through-hole 201. The conductive adhesive is electrically connected to the SCF metal layer, so that static electricity generated at the edge of the through-hole can be conducted to the SCF metal layer for grounding. Coating the wall of the through-hole with conductive adhesive allows for further dissipation of static electricity accumulated at the edge of the through-hole through another discharge path, thereby further preventing green discoloration or bright spots and ensuring display quality.

[0078] In an optional embodiment of this application, the conductive adhesive can be disposed along the sidewall of the through hole to avoid affecting the light transmittance of the through hole.

[0079] In embodiments of this application, a display device is also provided, wherein the display device includes a mid-frame, the mid-frame includes a receiving space, and a display module is at least partially located within the receiving space, the display module being the display module in any of the above embodiments.
