[0051] Figure 6 It is a structural block diagram of a terminal device according to an exemplary embodiment. DETAILED DESCRIPTION

[0052] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0053] Currently, due to cost requirements, many terminal devices often use magnesium alloy plastic middle frames (MDA middle frames). In this way, some static electricity in the external electrostatic field may be transmitted to the inside of the display through the middle frame, causing abnormal display. Figure 1 , Figure 1 This is a schematic diagram of an abnormal screen display in the related art; wherein, Figure 1 There is an abnormal area S at the edge of the display screen.

[0054] In the related art, in order to solve the problem of electrostatic protection, the following electrostatic protection schemes are usually adopted: The first electrostatic protection scheme is based on the human body model (HBM) protection scheme, in which HBM protection simulates the electrostatic discharge phenomenon generated when the human body contacts the device with electricity, and evaluates the anti-static ability of the device under this condition. In the HBM scheme, it is necessary to form a metal layer (Mask) by coating inside the display screen and avoid the existing device layer in the display screen. Not only is the process difficult, but it also increases the cost and structural thickness of the display screen. The second electrostatic protection scheme is to apply silver paste to the corners of the display screen. However, the solution of applying silver paste to the corners of the display screen has little effect on the improvement of static electricity generated on the side, and the cost is also very high.

[0055] In view of this, the present disclosure provides a display module. Figure 2 , Figure 2 A schematic diagram of a display module according to an exemplary embodiment is shown. Figure 1 ; Wherein, the display module 1 includes:

[0056] Display component 11, used for screen display;

[0057] The electrostatic protection structure 12 is disposed at at least one side of the display component 11 and partially surrounds the display component 11 to shield the display module 1 from charge interference from outside the display module 1 .

[0058] Here, the display module proposed in the embodiment of the present disclosure is applied to a terminal device with a display function, and is used to display images through the display component inside the display module; the display module can be an OLED display screen, such as a passive matrix OLED (Passive Matrix OLED, POLED) or an active matrix OLED display screen (Active Matrix OLED, A-OLED). Of course, the display module can also be a liquid crystal (LCD) display screen, and the present disclosure does not limit this. In the embodiment of the present disclosure, the display component includes devices and connecting circuits for displaying images; taking the display module as an OLED display screen as an example, the above-mentioned display component includes at least an OLED panel; wherein, if the OLED display screen has a touch function, the display component also includes a touch panel, and the touch panel is arranged between the cover plate on the top of the display module and the OLED panel.

[0059] Among them, the OLED panel is provided with a supporting substrate, an anode layer, an organic layer, a cathode layer and an encapsulation layer; among them, the material of the supporting substrate can be glass or flexible plastic, and the supporting substrate is used to support the OLED panel, increase the anti-extrusion ability of the OLED panel, and protect the other functional layers mentioned above in the OLED panel; the anode layer generally adopts a transparent conductive material, such as indium tin oxide (ITO), etc., for injecting holes; the cathode layer usually adopts a metal material, such as aluminum or magnesium silver alloy, for injecting electrons; the organic layer includes a hole injection layer, a hole transport layer, a light-emitting layer, an electron transport layer, etc. In the light-emitting layer, electrons and holes will combine to form excitons, and the excitons will de-excite to emit light, thereby generating light of different colors for the color display of the picture; the encapsulation layer is used to protect the organic layer and electrodes inside the OLED panel, reduce the intrusion of harmful substances such as moisture and oxygen, and extend the service life of the OLED display panel.

[0060] In the embodiment of the present disclosure, the electrostatic protection structure is arranged at a position on at least one side of the display component. The electrostatic protection structure can be attached to the side of the display component, or there can be a gap between the side of the display component, but the gap needs to be set within a preset gap range to ensure the electrostatic protection effect; exemplarily, the preset gap range is less than 1 nanometer.

[0061] Here, the embodiment of the present disclosure sets the electrostatic protection structure outside the display component. Compared with adding a metal shielding film layer inside the display component, it not only has less process difficulty and lower cost, but also reduces the structural thickness of the display module to a certain extent, meeting the lightweight and thin design pursued by the display module.

[0062] Among them, the electrostatic protection structure is conductive and extends along the side of the display component, so it can serve as a freely grounded conductive component to quickly guide the charges attached to the electrostatic protection structure to the ground, reducing the display anomalies caused by the accumulation of charges from the external electrostatic field here and then entering the display screen. In this way, the electrostatic protection structure can play a role in shielding charge interference from outside the display module.

[0063] In the embodiment of the present disclosure, the electrostatic protection structure is arranged at a position on at least one side of the display component and partially surrounds the display component. It can be manifested as the electrostatic protection structure covering at least one side of the display component but not contacting other structures connected to the display component; of course, it can also be manifested as one end of the electrostatic protection structure being connected to the structure on the display side of the display component and the other end being connected to the structure on the non-display side, thereby achieving the effect of surrounding the side of the display component.

[0064] It should be noted that the length of the electrostatic protection structure can be the same as the side length of the display component, or it can be greater than the length of the display component; when the display module in the present disclosure has multiple sides, the above-mentioned electrostatic protection structure can be set at the positions of multiple sides to increase the range of electrostatic protection.

[0065] In the disclosed embodiments, an electrostatic protection structure is provided by spraying or depositing a conductive material on at least one side of the display component during the display module manufacturing process to form the electrostatic protection structure. The conductive material of the electrostatic protection structure may include a metal material, a metal oxide material, or a semiconductor material, etc., which is not limited in the disclosed embodiments. The electrostatic protection structure formed after spraying or depositing the conductive material has internal continuity, allowing for rapid charge flow and reducing charge accumulation.

[0066] In the disclosed embodiment, an electrostatic protection structure is provided on at least one side of the display component of the display module, and the electrostatic protection structure partially surrounds the display component; in this way, the electrostatic protection structure can quickly guide the charges in the electrostatic field from outside the display module to the ground, thereby reducing the damage to the components caused by the accumulation and flow of charges to the internal components of the display module, improving the display anomalies caused by external electrostatic interference, and improving the display effect and service life of the display module.

[0067] In some embodiments, combined Figure 2 , the display module 1 further includes:

[0068] a protective substrate 13 on which the display assembly 11 is disposed;

[0069] a cover plate 14 , disposed on a display side of the display assembly 11 away from the protective substrate 13 , and covering the display assembly 11 ;

[0070] The electrostatic protection structure 12 is connected to the protection substrate 13 , and / or the electrostatic protection structure 12 is connected to the cover plate 14 .

[0071] It should be noted that Figure 2 The display module 1 is an inverted diagram; when the display module 1 is applied to a terminal device, the cover plate 14 is located on the side away from the middle frame of the terminal device (i.e., above the display component 11), and the protective substrate 13 is located on the side close to the middle frame (i.e., below the display component 11).

[0072] Among them, the above-mentioned protective substrate is used as a protective component of the display component in the display module, which is used to support and protect the devices and circuits in the display component and enhance the stability of the display screen. In some examples, the protective substrate can be set as a plastic plate or a glass plate; in other examples, the protective substrate can also be set as a screen cooling film (SCF), wherein the SCF includes a glue layer, a foam layer and a copper foil layer. Here, the SCF is adhered to the bottom of the display component through a glue layer such as a grid glue, and the foam layer is arranged between the glue layer and the copper foil layer for buffering and shock absorption; the copper foil layer is used for support and heat dissipation.

[0073] In the embodiment of the present disclosure, the cover plate covers the display surface of the display component and is the outer glass cover plate (Cover Glass, CG) of the display module. It is mainly used to protect the internal display component, reduce the impact or scratches on the display module during use, and improve the safety and stability of the display module.

[0074] Here, the CG cover is primarily made of tempered glass and ink. The inks include main body ink, cover ink, and character ink. Furthermore, when the display module is used in mobile phones or tablets, the CG cover is often coated with an anti-fingerprint film to improve touch smoothness and softness and prevent scratches.

[0075] The electrostatic protection structure proposed in the embodiment of the present disclosure can be extended to connect to the protection substrate and / or to the connection cover plate, which can increase the electrostatic protection range of the electrostatic protection structure and further enhance the electrostatic protection effect.

[0076] In some embodiments, see Figure 3 , Figure 3 1 is a schematic structural diagram of an electrostatic protection structure according to an exemplary embodiment; wherein the electrostatic protection structure 12 includes a first portion 121 and a second portion 122;

[0077] The first portion 121 partially covers the surface of the protective substrate 13 away from the display assembly 11;

[0078] The second portion 122 is respectively connected to the first portion 121 and the surface of the cover plate 14 facing the display assembly 11 .

[0079] here, Figure 3 The display module is also in an inverted view; when the display module is used in a terminal device, the cover plate 14 is located on the side away from the terminal device's middle frame (i.e., above the display component 11), while the protective substrate 13 is located on the side close to the middle frame (i.e., below the display component 11). The first portion 121 is disposed below the protective substrate 13 and partially covers the lower surface of the protective substrate 13. Thus, by extending the electrostatic protection structure 12 below the protective substrate 13, the present disclosure can guide electrostatic charges to a location farther away from the display component 11, thereby improving the electrostatic protection effect.

[0080] It should be noted that the first part partially covering the protective substrate includes: the first part is arranged at an edge position of the lower surface of the protective substrate.

[0081] here, Figure 3The second portion 122 is shown as being disposed on the lower surface of the cover plate 14 and arranged below the cover plate 14, juxtaposed with the display assembly 11. The second portion 122 can be attached to or spaced from the side of the display assembly 11. The second portion 122 is connected to the protective substrate 13 and the cover plate 14, respectively, to form a C-shaped protective space for the display assembly 11. This C-shaped protective space effectively shields against external electrical interference and protects the display assembly 11 within.

[0082] In the embodiment of the present disclosure, the thickness of the first portion and the thickness of the second portion are both less than a first preset thickness; illustratively, the first preset thickness is 500,000 Å; wherein A is one tenth of a nanometer (nm).

[0083] Among them, the thickness of the first part and the second part can be the same or different; there needs to be continuity between each position of the second part and the first part to ensure effective flow of charge; here the thickness of each position of the second part can be the same to ensure consistency of the structural design, and different thicknesses can also be set at each position of the second part to meet the pressure resistance requirements of different positions.

[0084] It should be noted that, for the preparation of the electrostatic protection structure, in some examples of the present disclosure, a conductive material can be sprayed or deposited on the surface of the protective substrate away from the display component to form a first part, and a conductive material can be sprayed or deposited on the side of the display component and the surface of the cover plate facing the display component to form a second part, wherein the second part is effectively connected to the first part when forming the second part to ensure the continuity of the charge flow; in other examples of the present disclosure, the display module can be blocked and part of the surface of the protective substrate away from the display component, and part of the surface of the side of the display component and the cover plate facing the display component can be exposed, and conductive material can be sprayed or deposited to simultaneously form a continuous first part and second part.

[0085] In the embodiment of the present disclosure, by providing the first part and the second part, the electrostatic protection range of the electrostatic protection structure is increased, and the design diversity and flexibility of the electrostatic protection structure are improved.

[0086] In some embodiments, a heat dissipation layer is provided on a surface of the protective substrate away from the display component; and the first portion is connected to the heat dissipation layer.

[0087] Here, the heat dissipation layer can be the copper foil layer in the SCF proposed above in this disclosure; wherein, the heat dissipation copper foil has good heat dissipation performance and can quickly conduct away the heat generated by the display screen or other terminal devices; the heat dissipation copper foil also has good conductive performance and can conduct away charges to avoid charge accumulation.

[0088] In the embodiment of the present disclosure, the heat dissipation layer may also be a graphite layer or the like.

[0089] The first part and the heat dissipation layer proposed in the embodiment of the present disclosure can be overlapped or fixed and bonded with conductive glue, and the embodiment of the present disclosure does not limit this.

[0090] It should be noted that the heat dissipation layer can be located anywhere on the surface of the protective substrate away from the display assembly. For example, the heat dissipation layer can completely cover the surface or be located only at the edge of the surface. In the present disclosure, to reduce the structural thickness of the display module, the first portion is provided to connect to the heat dissipation layer at the edge of the surface.

[0091] The heat dissipation layer in the embodiment of the present disclosure has conductive properties, so the charges on the electrostatic protection structure can continue to flow to the heat dissipation layer, which increases the flow path of the charges on the electrostatic protection structure, allowing external charges to flow farther, reducing the phenomenon of external charges accumulating and entering the display module from the side of the display component, and improving the shielding effect against the external electrostatic field.

[0092] In some embodiments, the second portion has a first extension segment and a second extension segment; the first extension segment is connected to the second extension segment and has a connection angle with the second extension segment;

[0093] The first extension section is attached to at least one side of the display assembly and connected to the first portion;

[0094] The second extension section is attached to the surface of the cover plate facing the display component.

[0095] Here, combined Figure 3 The second portion 122 is formed by a first extension segment 122a and a second extension segment 122b, wherein the first extension segment 122a and the second extension segment 122b have different extension directions and have a connection angle, and the portion of the display component 11 close to the protective substrate 13 is located in the angle space of the connection angle.

[0096] In the present disclosure, one end of the first extension segment is connected to the second extension segment, and the other end is attached to the side of the display component, and extends along the side of the display component in a direction away from the cover plate to the first part; wherein, there is an angle between the first extension segment and the cover plate; in some examples, the angle is 90 degrees, that is, the first extension segment is perpendicular to the cover plate and parallel to the side of the display component; in other examples, the angle is less than 90 degrees, that is, the first extension segment is tilted toward the display component.

[0097] Correspondingly, the extension direction of the second extension section is different from the extension direction of the first extension section; wherein, the second extension section is attached to the surface of the cover plate facing the display component, one end is spaced apart from the display component, the spaced position has the first extension section, and the other end extends along the cover plate in the direction away from the display component.

[0098] Here, the first extension section is attached to the display component and extends as a key part for guiding the flow of charge, so the film layer of the first extension section has strict continuity, and the thickness of the first extension section exceeds the second preset thickness; here, the second preset thickness can be half of the first preset thickness, or 2 / 3, and the embodiments of the present disclosure do not limit this.

[0099] Furthermore, since the second extension section is used to connect to the cover plate to form a tight C-shaped protective space, the thickness of the second extension section can be less than the second predetermined thickness, thereby reducing the side width of the display module and improving the aesthetics of the display module.

[0100] In combination with the above disclosure, the first extension section and the second extension section can be provided as a whole, or can be formed separately and connected to each other. The process sequence of spraying or precipitation to form the second part in the embodiment of the disclosure is not described in detail here.

[0101] The embodiment of the present disclosure can improve the strictness of the electrostatic shielding space formed by the electrostatic protection structure and enhance the diversity and flexibility of the design of the electrostatic protection structure by providing the first extension section and the second extension section.

[0102] In some embodiments, the display assembly includes a first side and a second side disposed adjacently;

[0103] The electrostatic protection structure is arranged at the first side, and / or the electrostatic protection structure is arranged at the second side.

[0104] Here, the display component may have multiple sides, including a first side and a second side that are adjacently arranged. The electrostatic protection results proposed in the present disclosure may include one or more. An electrostatic protection structure may be arranged at the position of the first side or the second side. If there are multiple electrostatic protection structures, multiple electrostatic protection structures may be respectively arranged at the positions of the adjacent first side and the second side.

[0105] In some examples, the display module may be a separately arranged display screen having a long side and a short side, and the electrostatic protection structure may be arranged at any long side and / or short side.

[0106] In other examples, the display module may also be any screen of a spliced ​​screen in a folding display screen. In this case, the electrostatic protection structure may be provided at any side edge of the screen that is not connected to the hinge.

[0107] In addition, because the physical length of the long side is longer, the charges in the electrostatic field outside the display module can more easily enter the interior of the display module from the long side. Therefore, the embodiment of the present disclosure can also selectively set the electrostatic protection structure at the position of the side with the longer length between the first side and the second side.

[0108] For example, see Figure 4 , Figure 4 Schematic diagram of an electrostatic protection structure according to an exemplary embodiment; wherein, in the embodiment of the present disclosure, the display assembly 11 includes two long sides L1 and L2 disposed opposite each other. Here, the electrostatic protection structure 12 includes two, one disposed at the position of the two long sides L1 and L2.

[0109] It should be noted that the aforementioned long side may be a side where a button module, such as a volume control button, a power button, or a mute button, is located. For example, of the two long sides, one has a volume control button, and the other has a power button. In the disclosed embodiment, two electrostatic protection structures are disposed on these two long sides, respectively. The electrostatic protection structures may be disposed away from the button module, or may be provided with an opening in communication with the button module.

[0110] In combination with the first part and the second part of the electrostatic protection structure proposed in the above embodiment of the present disclosure, the first part of one electrostatic protection structure and the first part of another electrostatic protection structure both partially cover the surface of the protective substrate away from the display component, and are respectively arranged at two opposite edges of the surface of the protective substrate away from the display component; in addition, the second part of one electrostatic protection structure and the second part of another electrostatic protection structure are both connected to the first part of their respective electrostatic protection structures; wherein, the second extension section of one electrostatic protection structure and the second extension section of another electrostatic protection structure are symmetrically arranged, and are both attached to the surface of the cover plate facing the display component; the first extension section of one electrostatic protection structure and the first extension section of another electrostatic protection structure are symmetrically arranged, and the display component is located between the two first extension sections; wherein, in order to ensure the consistency of the structural design, the thickness and width of the two first parts are consistent, the thickness and width of the two second extension sections are consistent, and the thickness and width of the two first extension sections are also consistent. Based on the above example, the display component may also include short sides, and the short sides are respectively connected to the two long sides; exemplarily, in combination with Figure 4 When the two long sides L1 and L2 included in the display assembly 11 in the embodiment of the present disclosure are both first sides, the second side may also be a short side L3 respectively connected to the two long sides L1 and L2.

[0111] The electrostatic protection structure 12 may also be provided at the position of the short side L3.

[0112] In combination with the above disclosure, the first portion of the electrostatic protection structure also partially covers the surface of the protection substrate away from the display component, the first extension section is attached to the short side, and the second extension section is attached to the cover plate.

[0113] In the disclosed embodiment, an electrostatic protection structure is also provided on the short side connected to the two long sides, which can improve the comprehensiveness of electrostatic protection for the display module.

[0114] It should be noted that, since a metal structure is usually provided at the USB interface of a terminal device, the above-mentioned electrostatic protection structure is usually not provided on the side on the same side as the USB interface in the display module proposed in the embodiment of the present disclosure.

[0115] In the embodiment of the present disclosure, an electrostatic protection structure can be provided on any side of two adjacent sides, which improves the flexibility of the present disclosure in providing the electrostatic protection structure.

[0116] In some embodiments, the electrostatic protection structure includes a first electrostatic protection structure and a second electrostatic protection structure;

[0117] The first electrostatic protection structure is arranged at the position of the first side;

[0118] The second electrostatic protection structure is arranged at the position of the second side;

[0119] The first electrostatic protection structure and the second electrostatic protection structure are connected to form an enclosing structure, and the enclosing structure encloses the first side and the second side.

[0120] Here, the first part of the first electrostatic protection structure is connected to the first part of the second electrostatic protection structure; the second part of the first electrostatic protection structure is connected to the second part of the second electrostatic protection structure; in this way, the formed enclosing structure has continuity, which can reduce the external charge from entering the display module from at least two directions, thereby improving the electrostatic shielding effect of the display component.

[0121] like Figure 4 As shown, the first side can be the long side L1 and L2, in which case there are two first electrostatic protection structures 12a, and the second side can be the short side L3, in which case there is one second electrostatic protection structure 12b. In this case, the second electrostatic protection structure 12b is respectively connected to the two oppositely arranged first electrostatic protection structures 12a. In this way, the formed enclosing structure has continuity, which can reduce the external charge from entering the display module from at least three directions, thereby improving the electrostatic shielding effect of the display component.

[0122] Here, when the display module has two short sides, the two second electrostatic protection structures and the two first electrostatic protection structures can be connected in sequence to form a closed space for the display component, so that external charges cannot enter the display component, further improving the anti-static interference effect.

[0123] In the embodiment of the present disclosure, the surrounding structure formed by connecting the first electrostatic protection structure and the second electrostatic protection structure can effectively improve the anti-static interference effect.

[0124] In some embodiments, combined Figure 3 As shown, the display assembly 11 includes:

[0125] The display panel 111 is provided on the protective substrate 13;

[0126] The first optical adhesive layer 112 is disposed between the display panel 111 and the cover plate 14 .

[0127] Among them, the display panel can be the OLED panel proposed in the above embodiment of the present disclosure, which is used to realize picture display by driving pixels to emit light; in other examples, if the display module is a liquid crystal display screen, then the display panel can also be a liquid crystal layer, and a backlight layer can also be set in the display component, and the backlight layer is set between the liquid crystal layer and the above protective substrate.

[0128] In the disclosed embodiments, the optical adhesive layer (OCA) is a transparent double-sided adhesive layer. Due to its high adhesion, the OCA is primarily used to secure the display panel in place within the display module, enhancing structural stability. Furthermore, the OCA offers high clarity, strong light transmittance, and UV resistance, so its placement between the display panel and the cover plate can enhance the display quality.

[0129] The display panel and optical adhesive layer proposed in the embodiments of the present disclosure can ensure that the display module can display images stably and effectively.

[0130] In some embodiments, the display assembly further includes a polarizer; the polarizer is disposed between the display panel and the first optical adhesive layer;

[0131] or,

[0132] The display panel is provided with a packaging structure, and the packaging structure is located on a side of the display panel facing the first optical adhesive layer; the display module further includes a filter layer, and the filter layer is provided in the packaging structure.

[0133] Among them, a polarizer is provided in the display module of some examples; see Figure 3 , Figure 3 A polarizer 113 is exemplified.

[0134] In the disclosed embodiment, a polarizer is covered on the surface of the display panel away from the protective substrate, and is used to control the polarization direction of the light emitted from the display panel. Taking the OLED panel as an example, the polarizer can be set as a circular polarizer and used to block reflected light to improve the visibility and contrast of the display module under strong light. When external natural light shines on the OLED panel, the light will penetrate the encapsulation layer and reach the cathode layer and be reflected back, which will cause the display effect and contrast of the display module to decrease. In this way, the circular polarizer can effectively improve the screen display effect by utilizing its polarization characteristics to block these reflected lights.

[0135] Here, the circular polarizer includes a linear polarizer and a quarter glass plate, which work together to form left-handed circularly polarized light, and then turn it into right-handed circularly polarized light after being reflected by the cathode layer, so as to block the reflected light.

[0136] In some other display module examples, the display module does not include a polarizer, such as a polarless display module. In this embodiment, the portion of the display panel facing the first optical adhesive layer is provided with an encapsulation structure for the display panel. This encapsulation structure (which can be understood as the encapsulation layer mentioned above) is used to encapsulate some optical components in the display panel. The filter layer includes a color filter (CF) layer, which is provided within the encapsulation structure and is used to filter light, allowing light of specific wavelengths to pass through while blocking light of other wavelengths, thereby generating red, green, and blue (RGB) primary colors. These primary colors are then combined to ultimately present a rich color.

[0137] The electrostatic protection structure proposed in the embodiment of the present disclosure can be set in a display module with a polarizer, and can also be set in a display module without a polarizer, which broadens the scene diversity of the electrostatic protection structure design and improves the setting flexibility.

[0138] In some embodiments, the cover plate is an ultra-thin glass (UTG) cover plate.

[0139] The cover plate proposed in the embodiment of the present disclosure can be implemented as an ultra-thin glass (UTG) cover plate. The UTG cover plate not only has the basic functions of glass, but also has the characteristics of being light, thin, and flexible.

[0140] Among them, the thickness of UTG is usually between 1.2mm and 0.1mm, and it can be bent, so it can be used in foldable devices.

[0141] It should be noted that UTG cover plates are usually used in pollless display modules.

[0142] The embodiment of the present disclosure can broaden the usage scenarios of the display module by providing an ultra-thin glass UTG cover.

[0143] In some embodiments, the display module further includes:

[0144] a transparent protective layer, disposed on a side of the UTG cover plate away from the display panel and covering the UTG cover plate;

[0145] The second optical adhesive layer is arranged between the transparent protective layer and the UTG cover plate.

[0146] See also Figure 5 , Figure 5 The structure of the display module according to an exemplary embodiment is shown Figure 2 ; Combine Figures 2 to 5 , the cover plate 14 of the display module 1 is a UTG cover plate 141; at this time, the display module 1 also includes: a transparent protective layer 15, which is arranged on the side of the flexible glass cover plate 141 away from the display panel 111 and covers the UTG cover plate 141; a second optical adhesive layer 16, which is arranged between the transparent protective layer 15 and the UTG cover plate 141.

[0147] Here, the transparent protective layer can be a protective layer formed of glass material or a protective layer formed of polyethylene terephthalate (PET) material, which is used to protect the display module and reduce scratches and wear on the screen. The material of the second optical adhesive layer can be the same as or different from the material of the first optical adhesive layer, and this embodiment of the present disclosure is not further described.

[0148] In the embodiment of the present disclosure, a transparent protective layer is provided to effectively protect the display module and reduce scratches and wear on the screen.

[0149] In some embodiments, the material of the electrostatic protection structure includes a metal material, a metal oxide material, or a non-metallic material;

[0150] The metal material at least includes silver paste material, the metal oxide material at least includes indium tin oxide; and the non-metallic material at least includes carbon powder.

[0151] The electrostatic protection structure comprises a conductive material, which includes a metal material, a metal oxide material, or a non-metallic material. Here, the non-metallic material includes carbon powder, and may also be graphite, graphene, tellurium, etc.

[0152] In some examples of the present disclosure, carbon powder (C powder) may be used to form an electrostatic protection structure by spraying the C powder onto the sides of the display assembly, the protective substrate, and the corresponding positions of the cover plate using an electrospinning process. Electrospinning coating is a process that uses a strong electric field to form a jet stream for spinning. Through the electrospinning process, the C powder can be evenly dispersed on the sides of the display assembly, the protective substrate, and the corresponding positions of the cover plate to form a layer of carbon powder coating. This dispersed structure helps to evenly distribute the charge and reduce the possibility of localized charge accumulation.

[0153] In the embodiment of the present disclosure, the metal material may be copper, aluminum or silver.

[0154] In some examples, a metal electrostatic protection structure may be provided on the side of the display component by evaporating the evaporated material (such as the copper material or aluminum material mentioned above) into atoms or molecules through methods such as current heating, electron beam bombardment heating, or laser heating. These atoms or molecules move in a straight line with a large free path in a vacuum, collide with the corresponding positions of the display component, the protective substrate, and the cover plate, and then condense to form a first extension section attached to the display component, a first part attached to the protective substrate, and a second extension section deposited on the cover plate.

[0155] In other examples, the electrostatic protection structure on the side of the display assembly can be provided by mixing silver powder and glass powder to form a silver paste solution, and then spraying the prepared silver paste solution on the side of the display assembly using a spray coating device. After spraying, the solvent is allowed to evaporate and solidify, forming a silver paste spray coating.

[0156] Silver paste has excellent electrical conductivity, directing charges from external electrostatic fields away from the display components, creating a shielding effect for the display components. Furthermore, silver paste is corrosion-resistant and maintains stable electrical conductivity in various environments, ensuring the long-term effectiveness of ESD protection.

[0157] In the embodiment of the present disclosure, the metal oxide material may be zinc oxide, indium tin oxide, or the like.

[0158] In some examples, zinc oxide has excellent electrical conductivity and oxidation resistance, and can be formed on the side of the display component by coating or spraying to form a zinc oxide coating film.

[0159] In some other examples, the metal oxide material forming the ESD protection structure can also be indium tin oxide (ITO). ITO is a substitutional solid solution of indium (III) oxide (In2O3) and tin (IV) oxide (SnO2), typically with a mass ratio of 90% In2O3 and 10% SnO2. ITO is a transparent conductive material that can provide excellent electrical conductivity while maintaining high light transmittance.

[0160] Here, the method of setting up an electrostatic protection structure on the side of the display component can be: blocking the area outside the corresponding positions of the side of the display component, the protective substrate and the cover plate, sputtering the ITO material to the unblocked position, and forming an ITO coating after high-temperature annealing. It should be noted that in order to ensure the tolerance of the display module screen, the temperature for preparing the ITO coating needs to be lower than 80 degrees Celsius. Here, when there is an external electrostatic field, the ITO coating can quickly conduct the charge away, reducing the damage caused by static electricity to the components inside the display component.

[0161] In the embodiments of the present disclosure, different preparation processes can be adopted and different materials can be used to prepare the electrostatic protection structure proposed in the embodiments of the present disclosure, thereby improving the flexibility and comprehensiveness of preparing the electrostatic protection structure.

[0162] In some embodiments, the thickness of the electrostatic protection structure is within a predetermined thickness range.

[0163] In conjunction with the above-mentioned embodiments of the present disclosure, the first portion of the electrostatic protection structure, the first extension section of the second portion, and the second extension section are all less than the first predetermined thickness. Taking the first predetermined thickness as 500,000 Å as an example, the predetermined thickness range is between 1 and 500,000 Å. Of course, the thickness of the first extension section and the second extension section can be set as required, and this embodiment will not be described in detail here.

[0164] Here, in combination with the various preparation processes for preparing the electrostatic protection structure proposed above in this disclosure, when using different materials to prepare different electrostatic protection structures, the thickness requirements for the electrostatic protection structure are also different. Specifically, when the electrostatic protection structure is an ITO coating, the preset thickness range corresponding to the film layer thickness can be 5-200A; when the electrostatic protection structure is a silver paste spray coating, the preset thickness range corresponding to the film layer thickness can be 1-500,000A; when the electrostatic protection structure is a carbon powder coating, the preset thickness range corresponding to the film layer thickness can be 5-500,000A.

[0165] It should be noted that the thickness of the electrostatic protection structure in the embodiment of the present disclosure is within a preset range, which can achieve electrostatic shielding of the display module while reducing the overall structural thickness of the display module as much as possible, thereby realizing a narrow-frame design for the terminal device.

[0166] The present disclosure also provides a terminal device, wherein the terminal device includes:

[0167] middle frame;

[0168] The display module proposed in the above embodiment is assembled on the middle frame.

[0169] Here, the midframe can be a metal midframe or an MDA midframe, which is not limited in this embodiment. The midframe supports and mounts the various functional modules in the terminal device; the functional modules installed on the midframe include: a battery module, a processing module (including a core processor), and the aforementioned display module.

[0170] The terminal devices proposed in the embodiments of the present disclosure include fixed terminals, mobile terminals or portable electronic devices; the fixed terminals include but are not limited to vehicle-mounted terminals, televisions, etc.; the mobile terminals include but are not limited to mobile phones, tablet computers, etc.; the portable electronic devices include but are not limited to smart watches, etc., and the embodiments of the present disclosure do not impose further restrictions on this.

[0171] The following takes a mobile phone as an example of a terminal device to illustrate an exemplary application of a display module in a mobile phone.

[0172] Combine Figure 3 The electrostatic protection structure 12 can be a metal film layer formed by spraying or depositing on the side of the display module 1. Specifically, in the electrostatic protection structure 12, the first portion 121 is a lapped layer in the metal film layer. Copper foil is provided on the surface of the protective substrate 13SCF, serving as the lapped layer of the electrostatic protection structure 12. The first extension 122a of the second portion 122 is a key film layer in the metal film layer, having a moderate thickness and a continuous film layer. The second extension 122b of the second portion 122 is a deposited redundant layer in the metal film layer, and the thickness of this portion can be less than the second predetermined thickness.

[0173] In the above embodiment, the electrostatic protection structure may also be silver paste spray coating, ITO coating or carbon powder coating. The preparation process may refer to the above description of the present disclosure, and the present disclosure will not elaborate further here.

[0174] It can be understood that the electrostatic protection structure proposed in the embodiment of the present disclosure is arranged on the side of the display module, which can not only reduce the preparation cost of the display screen, but also reduce the impact of the external electrostatic field on the display, and reduce the customer return rate of mid-terminal equipment, thereby improving the quality and reputation of the product.
