[0067] It should be noted that the sizes and shapes of the figures in the accompanying drawings do not reflect the actual scale and are only for the purpose of illustrating the present disclosure. The same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions.

[0068] An embodiment of the present disclosure provides a display panel, as shown in FIG1 , comprising:

[0069] Display substrate 12

[0070] A light-transmitting film 11 is located on the light-emitting side of a display substrate 12. The light-transmitting film 11 includes a substrate 1, an antibacterial layer 2 located on one side of the substrate 1, and an anti-fingerprint layer 4 located on the side of the antibacterial layer 2 facing away from the substrate 1. The antibacterial layer 2 includes a light-transmitting substrate 201 and an antibacterial metal complex 202. The light-transmitting substrate 201 includes hydrophilic groups. The anti-fingerprint layer 4 has a contact angle greater than 100° and less than or equal to 150°.

[0071] The display panel provided by the embodiment of the present disclosure comprises a light-transmitting film attached to the light-emitting side of the display substrate. The light-transmitting film includes an antibacterial layer, which includes a light-transmitting substrate and an antibacterial metal complex. The hydrophilic groups included in the light-transmitting substrate can fully absorb water vapor in the air and on the surface of the film material. The water vapor induces the antibacterial metal complex to release antibacterial metal ions, thereby achieving the effect of killing bacteria and viruses, preventing the residue and growth of bacteria and viruses on the surface of the light-transmitting film, preventing the surface of the light-transmitting film from becoming a source of bacterial and viral contamination and further spread, thereby improving the antibacterial and viral resistance of the display panel. The light-transmitting film also includes an anti-fingerprint layer, which can prevent stains and other residues and improve the antibacterial effect. The contact angle of the anti-fingerprint layer is greater than 100° and less than or equal to 150°, which can prevent stains from remaining while also preventing the contact angle from being too large, which would prevent water vapor from remaining and affect the antibacterial performance.

[0072] In some embodiments, the display substrate is one of the following: a liquid crystal display substrate, an electroluminescent display substrate, such as an organic light emitting diode display substrate, a quantum dot display substrate, or a micro-sized inorganic light emitting display substrate.

[0073] In a specific implementation, the display substrate may be a non-touch display substrate, or the display substrate may be a touch display substrate.

[0074] In some embodiments, the light-transmitting substrate includes one or a combination of the following: polyacrylate resin, polyacetate, polycarbonate, polyimide, and polyolefin resin.

[0075] In practice, the transparent substrate can be made of a material with a high transmittance, thereby preventing the antibacterial layer from affecting the overall transmittance of the transparent film. Furthermore, when the transparent film is applied to a display product, it can avoid affecting the transmittance of the display product and the display effect.

[0076] In a specific implementation, polyacrylate resins are commonly used as light-transmitting substrates with relatively high transmittance. The light-transmitting substrate of the antibacterial layer can be a polyacrylate resin. An example of a polyacrylate resin is an acrylic polymer as shown in FIG2 . In FIG2 , R1 and R2 are both hydrophilic groups. Examples of hydrophilic groups include one or a combination of the following: hydroxyl, carbonyl, carboxyl, and ketone.

[0077] In some embodiments, the antimicrobial metal complex comprises one or a combination of the following: a silver complex, a copper complex, a zinc complex, or a titanium complex.

[0078] Next, taking the antibacterial layer including a silver complex as an example, the antibacterial and antiviral effects of the antibacterial layer are illustrated. Water vapor induces the silver complex to release silver ions (Ag+). The antibacterial rate of Ag+ against bacteria is shown in Table 1. The antibacterial rate of Ag+ against Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Staphylococcus epidermidis, and Klebsiella pneumoniae is all above 99%. The antiviral rate of Ag+ against bacteria is shown in Table 2. The antiviral rate of Ag+ against influenza A virus H1N1, influenza A virus H3N2, human enterovirus EV71, and human coronavirus Hcov229E is approximately 90%. This shows that the absorption of water vapor by hydrophilic groups to induce the release of Ag+ can effectively prevent bacteria and viruses. In addition, the antibacterial and antiviral effects of Ag+ can last for more than 5 years.

[0080] Table 2

[0081] In some embodiments, in the antibacterial layer, the mass fraction of the light-transmitting substrate is greater than or equal to 50% and less than or equal to 95%, and the mass fraction of the antibacterial metal complex is greater than or equal to 1% and less than or equal to 10%.

[0082] In some embodiments, the thickness of the substrate is greater than or equal to 20 microns and less than or equal to 80 microns;

[0083] The thickness of the antibacterial layer is greater than or equal to 5 micrometers and less than or equal to 7 micrometers.

[0084] In a specific implementation, if the display panel is applied to a portable display product such as a notebook, the thickness of the base of the light-transmitting film is greater than or equal to 20 microns and less than or equal to 40 microns; if the display panel is applied to a display product such as a monitor, the thickness of the base of the light-transmitting film is greater than or equal to 60 microns and less than or equal to 80 microns.

[0085] In practice, the thicker the substrate, the better the waterproof and support performance of the transparent film. Increasing the substrate thickness can improve the waterproof and support performance of the transparent film. Furthermore, to improve the performance of the transparent film, the substrate thickness is greater than or equal to 40 microns and less than or equal to 80 microns.

[0086] During specific implementation, a suitable substrate thickness can be selected according to actual product requirements.

[0087] In some embodiments, the material of the substrate includes polyethylene glycol terephthalate (PET) or triacetyl cellulose (TAC).

[0088] In a specific implementation, the thickness of the PET substrate can generally be thicker than that of the TAC substrate. When the thickness of the PET substrate is greater than or equal to 40 microns and less than or equal to 80 microns, the waterproof effect and support effect of the light-transmitting film are better.

[0089] In some embodiments, as shown in FIG. 3 , the antibacterial layer 2 further includes scattering particles 203 .

[0090] In the light-transmitting film provided by the embodiment of the present disclosure, the antibacterial layer includes scattering particles, thereby increasing the haze of the antibacterial layer and further improving the light emission uniformity of the light-transmitting film.

[0091] In some embodiments, the antimicrobial layer has a haze greater than or equal to 1% and less than or equal to 50%.

[0092] In some embodiments, the material of the scattering particles includes silicon oxide (SiO 2 ).

[0093] In specific implementations, the mass fraction of the scattering particles in the antibacterial layer can be selected according to the required haze. For example, the mass fraction of the scattering particles in the antibacterial layer is greater than 0 and less than or equal to 50%.

[0094] In some embodiments, as shown in FIG. 4 to FIG. 7 , the light-transmitting film further includes:

[0095] The polarizing functional layer 3 is located on the side of the substrate 1 facing away from the antibacterial layer 2 .

[0096] The display panel provided by the embodiment of the present disclosure has a light-transmitting film further including a polarizing functional layer, so that the light-transmitting film integrates the function of a polarizer. The light-transmitting film can replace the traditional polarizer located on the light-emitting side of the display panel, and while realizing the function of the polarizer, it can also improve the antibacterial and antiviral properties of the display panel.

[0097] In a specific implementation, as shown in Figures 4 to 7 , the display substrate 12 is a liquid crystal display substrate 12. That is, the transparent film 11 can function as an upper polarizer on the liquid crystal display substrate 12 while also achieving antibacterial and antiviral effects. The liquid crystal display substrate 12 includes an array substrate 1201 and an opposing substrate 1202 disposed opposite each other, and a liquid crystal layer 1203 located between the array substrate 1201 and the opposing substrate 1202.

[0098] In some embodiments, as shown in FIG. 4 to FIG. 7 , the polarizing functional layer 3 includes: a polarizing layer 301 and at least one protective layer 302 ;

[0099] The protective layer 302 is located between the polarizing layer 301 and the substrate 1 , and / or the protective layer 302 is located on a side of the polarizing layer 301 facing away from the substrate 1 .

[0100] The optical film in the display panel provided by the embodiment of the present disclosure has a protective layer disposed on at least one side of the polarizing layer, which can improve the supporting strength of the polarizing layer and also improve the waterproof performance of the optical film.

[0101] It should be noted that, FIG4 and FIG6 are illustrated by taking the antibacterial layer not including scattering particles as an example, and FIG5 and FIG7 are illustrated by taking the antibacterial layer not including scattering particles as an example.

[0102] In some embodiments, as shown in FIG. 4 and FIG. 5 , the substrate 1 is reused as a protective layer; the polarizing functional layer further includes a protective layer 302 located on a side of the polarizing layer 301 away from the substrate 1 .

[0103] In some embodiments, as shown in Figures 6 and 7, the polarizing functional layer 3 includes two protective layers 302, namely a first protective layer 3021 and a second protective layer 3022. The first protective layer 3021 is located between the polarizing layer 301 and the substrate 1, and the second protective layer 3022 is located on the side of the polarizing layer 301 away from the substrate 1.

[0104] In a specific implementation, the polarizing functional layer includes two protective layers, which can increase the thickness of the polarizing functional layer and thus increase the thickness of the transparent film, and can improve the waterproof performance of the transparent film, so that the transparent film can maintain stable performance even in a high temperature and high humidity environment.

[0105] In some embodiments, the thickness of the substrate is greater than the thickness of the protective layer between the polarizing layer and the substrate, and / or the thickness of the substrate is greater than the thickness of the protective layer on the side of the polarizing layer facing away from the substrate.

[0106] In some embodiments, the thickness of the polarizing functional layer including the double protective layer is, for example, greater than or equal to 110 microns. When the substrate is a PET substrate, the thickness of the PET substrate is greater than or equal to 40 microns and less than or equal to 80 microns. The thickness of the antibacterial layer is greater than or equal to 45 microns and less than or equal to 7 microns. The thickness of the transparent film layer including the polarizing layer is, for example, greater than 200 microns, thereby improving the support performance and waterproof performance of the transparent film.

[0107] In some embodiments, the material of the polarizing layer includes polyvinyl alcohol (PVA).

[0108] In some embodiments, the material of the protective layer includes PET or TAC.

[0109] In some embodiments, a bonding layer is further included between the protective layer and the polarizing layer, and the bonding layer includes a glue material; that is, the protective layer and the polarizing layer are bonded to each other via the glue material.

[0110] In some embodiments, as shown in FIG. 4 to FIG. 9 , the display panel further includes:

[0111] The pressure-sensitive adhesive 5 is located between the light-transmitting film 11 and the display substrate 12 .

[0112] That is, the light-transmitting film is bonded to the display substrate via a pressure-sensitive adhesive.

[0113] In some embodiments, as shown in FIG. 4 to FIG. 9 , the pressure-sensitive adhesive 5 includes: an adhesive material and a conductive material 501 mixed with the adhesive material.

[0114] In the display panel provided by the embodiments of the present disclosure, the pressure-sensitive adhesive between the transparent film and the display substrate includes a conductive material. When the transparent film is attached to the light-emitting surface of the display substrate, the conductive material can guide accumulated charges on the display substrate surface, preventing charge accumulation. This can particularly prevent touch defects caused by charge accumulation in touch-sensitive display substrates.

[0115] In a specific implementation, as shown in FIG8 and FIG9 , the transparent film 11 does not include a polarizing functional layer, and the base 1 is attached to the surface of the display substrate 12 via the pressure-sensitive adhesive 5 on the side facing away from the antibacterial layer 2 .

[0116] Alternatively, in a specific implementation, as shown in Figures 4 to 7, the transparent film 11 includes a polarizing functional layer 3, and the transparent film 11 also includes a pressure-sensitive adhesive 5 located between the substrate 1 and the polarizing functional layer 3; for the sake of convenience in distinguishing, the pressure-sensitive adhesive 5 located between the substrate 1 and the polarizing functional layer 3 is the first pressure-sensitive adhesive 5-1, and the pressure-sensitive adhesive 5 located between the polarizing functional layer 3 and the display substrate 12 is the second pressure-sensitive adhesive 5-2; that is, the substrate 1 is bonded to the polarizing functional layer 3 through the first pressure-sensitive adhesive 5-1, and the transparent film is attached to the surface of the display product through the second pressure-sensitive adhesive 5-2.

[0117] In some embodiments, the conductive material is, for example, bis(trifluoromethylsulfonyl)imide.

[0118] In some embodiments, the mass fraction of the conductive material is greater than 0 and less than 5%, thereby achieving charge conduction while ensuring pressure-sensitive adhesive adhesion.

[0119] In some embodiments, the light-emitting side of the substrate and / or the protective layer further includes a surface treatment layer.

[0120] During specific implementation, it is usually necessary to perform surface treatment on the substrate or protective layer to improve the uniformity of light output and thus prevent glare. Surface treatment is, for example, anti-glare (AG) surface treatment. AG surface treatment forms an uneven coating on the surface of the TAC layer or the PET layer with SiO2. This will cause uneven positions on the surface of the antibacterial layer, and stains and the like will easily remain in the uneven positions, reducing the contact area between the surface and bacteria and affecting the antibacterial effect. The display panel provided in the embodiment of the present disclosure, the light-transmitting film also includes an anti-fingerprint layer located on the side of the antibacterial layer away from the substrate, which can prevent stains and the like from remaining in the uneven positions and improve the antibacterial effect.

[0121] In some embodiments, the contact angle of the anti-fingerprint layer is, for example, 106°.

[0122] It should be noted that the anti-fingerprint layer provided in the embodiments of the present disclosure is disposed on the side of the antibacterial layer facing away from the substrate. This requires consideration not only of anti-fingerprint effectiveness but also of retaining water vapor, allowing the antibacterial layer to absorb water vapor and release antibacterial metal ions. The anti-fingerprint layer provided in the embodiments of the present disclosure has a contact angle of, for example, 106°, which balances the anti-fingerprint and water vapor retention effects. This prevents stains and other residues while also preventing excessive contact angles that prevent water vapor from remaining and impacting antibacterial performance.

[0123] In some embodiments, the material of the anti-fingerprint layer includes fluorine nanomaterials.

[0124] That is, in specific implementation, a fluorine nano coating can be sprayed on the surface of the antibacterial layer to form an anti-fingerprint layer.

[0125] Alternatively, a fluorine atom coating can be made on the surface of the antibacterial layer, or laser engraving / chemical etching / deposition methods can be used to form a surface nanostructure imitating the lotus leaf principle, forming a tiny air film to form a hydrophobic / oleophobic surface and an anti-fingerprint layer.

[0126] In some embodiments, the thickness of the anti-fingerprint layer is greater than or equal to 3 micrometers and less than or equal to 5 micrometers.

[0127] In some embodiments, the display substrate is a touch display substrate. As shown in FIG. 10 , FIG. 11 , and FIG. 12 , the display substrate 12 includes a plurality of sub-pixel units 13 and a plurality of touch electrodes 14 .

[0128] In some embodiments, as shown in FIG10 and FIG11 , the display substrate 12 is a liquid crystal display substrate; the array substrate 1201 includes: a first base substrate 15, a plurality of scan lines (not shown), a plurality of data lines 16, a plurality of sub-pixel units 13, and a common electrode 17 located on the side of the first base substrate 15 facing the liquid crystal layer 1203; the opposite substrate 1202 includes: a second base substrate 20, a color resist 18 and a black matrix 19 located on the side of the second base substrate 20 facing the liquid crystal layer 1203;

[0129] The sub-pixel unit 13 includes a thin film transistor 1301 and a pixel electrode 1302 located on a side of the thin film transistor 1301 facing away from the first substrate 15. The thin film transistor 1301 includes an active layer 13011, a gate G, a source S, and a drain D. The scan line is provided on the same layer as the gate G and is electrically connected thereto. The data line 16 is provided on the same layer as the source S and is electrically connected thereto. The pixel electrode 1302 is electrically connected to the drain D.

[0130] The black matrix 19 includes a plurality of first opening regions 1901 , and the color resist 18 is at least located within the first opening region 1901 .

[0131] In a specific implementation, the sub-pixel unit includes, for example, a red sub-pixel unit, a blue sub-pixel unit, and a green sub-pixel unit. Correspondingly, the color resist includes: a red color resist corresponding to the red sub-pixel unit, a blue color resist corresponding to the blue sub-pixel unit, and a green color resist corresponding to the green sub-pixel unit.

[0133] In a specific implementation, the line width of the strip extension portion is, for example, 2.6, and the width of the slit is about 4.5.

[0134] In some embodiments, as shown in Figure 10, the array substrate 1201 includes a plurality of touch electrodes 14, and the touch electrodes 14 are arranged in the same layer as the data lines 16. The touch electrodes 14 and the data lines 16 have the same extension direction. In a direction parallel to the plane where the first base substrate 15 is located, the touch electrodes 14 are located on one side of the data lines 16.

[0135] In the display panel provided by the embodiment of the present disclosure, the touch electrodes and the data lines are arranged in the same layer, and the two can be formed in the same patterning process, which can save process flow, save costs, and reduce the thickness of the display substrate.

[0136] In a specific implementation, the data line is usually an opaque metal line. As shown in FIG10 , the orthographic projections of the touch electrode 14 and the data line 16 on the first base substrate 15 are covered by the orthographic projection of the black matrix 19 on the first base substrate 15. This prevents the data line and the touch electrode from affecting the sub-pixel aperture ratio.

[0138] In some embodiments, as shown in FIG10 , the common electrode 17 is disconnected in the area between the touch electrode 14 and the data line 16 ; thus, a small capacitor is formed with the touch electrode 14 when a finger touches the touch electrode 14 , thereby realizing the touch function;

[0139] At the disconnection point, the edge of the common electrode 17 above the touch electrode 14 substantially overlaps with the edge of the touch electrode 14 , and the edge of the common electrode 17 above the data line 16 substantially overlaps with the edge of the data line 16 .

[0140] Alternatively, in some embodiments, as shown in FIG11 , the counter substrate 1202 includes a touch electrode 14 located on a side of the second base substrate 20 facing away from the black matrix 19. The touch electrode 14 is a transparent electrode made of, for example, indium tin oxide.

[0141] In a specific implementation, as shown in FIG11 , the common electrode 17 may be provided on the entire surface, with an opening only provided at the location where the pixel electrode 1302 and the drain electrode D are electrically connected.

[0142] Alternatively, in some embodiments, the touch display substrate is an electroluminescent display substrate, as shown in FIG12 , the display substrate includes: a first base substrate 15 , a sub-pixel unit 13 located on one side of the first base substrate 15 ;

[0143] The sub-pixel unit 13 includes: a thin film transistor 1301 and an electroluminescent device 29 located on the side of the thin film transistor 1301 facing away from the first substrate 15; the thin film transistor 1301 includes: an active layer 13011, a gate G, a source S and a drain D; the electroluminescent device 29 includes: a stacked anode 2901, a light-emitting functional layer 2902, and a cathode 2903;

[0144] The display substrate further includes: a pixel definition layer 28, an encapsulation layer 30 covering the electroluminescent device 29, and a touch function layer 31 located on a side of the encapsulation layer 30 facing away from the electroluminescent device 29; the pixel definition layer 28 is located on a side of the anode 2901 facing away from the first base substrate 15, and the pixel definition layer 28 includes a plurality of openings exposing the anode 2901; the encapsulation layer 30 includes, for example, an inorganic encapsulation layer / an organic encapsulation layer / an inorganic encapsulation layer in a stacked arrangement; the touch function layer 31 includes a plurality of touch electrodes 14;

[0145] The array substrate 1201 also includes: a buffer layer 21 located between the first base substrate 15 and the active layer 13011, a gate insulation layer 22 located between the active layer 13011 and the gate G, an interlayer insulation layer 23 located between the gate G and the source S and the drain D, and a planarization layer 25 located between the source S and the drain D and the anode 2901; the source S and the drain D are electrically connected to the active layer 13011 through vias penetrating the interlayer insulation layer 23 and the gate insulation layer 22, respectively, and the anode 2901 is electrically connected to the drain D through a via penetrating the planarization layer 25.

[0146] In a specific implementation, for example, the multiple touch electrodes include: multiple touch drive electrodes, multiple touch sensing electrodes, the touch functional layer includes a first touch conductive layer and a second touch conductive layer located on a side of the first touch conductive layer facing away from the encapsulation layer; the touch drive electrodes and the touch sensing electrodes each include multiple sub-electrodes, one of the touch drive electrodes and the touch sensing electrodes has multiple sub-electrodes electrically connected to each other, and the touch drive electrode and the other of the touch sensing electrodes are electrically connected via a bridging electrode; the first touch conductive layer includes the bridging electrode, and the second touch conductive layer includes the sub-electrodes. The touch functional layer also includes a touch insulating layer located between the first touch conductive layer and the second touch conductive layer.

[0147] In some embodiments, the display substrate is a non-touch display substrate, comprising a display function layer and an electrostatic discharge layer located on the side of the display function layer facing the light-transmitting film. Taking a liquid crystal display substrate as an example, as shown in FIG13 , all structures below the second base substrate 20 can be considered the display function layer, and the electrostatic discharge layer 27 is located on the side of the second base substrate 20 facing away from the black matrix 19.

[0148] Therefore, the static electricity of the display substrate can be removed through the static electricity lead-out layer, thereby avoiding display defects caused by charge accumulation.

[0149] It should be noted that Figure 13 illustrates the distance using a liquid crystal display substrate as an example. In a specific implementation, for an electroluminescent display substrate that does not include touch electrodes, the static electricity conduction layer can be disposed on the side of the encapsulation layer away from the electroluminescent device.

[0150] In a specific implementation, when the display substrate is a non-touch display substrate, as shown in FIG13 , since the display substrate 12 includes the static charge conduction layer 27, the pressure-sensitive adhesive 5 between the display substrate 12 and the light-transmitting film 11 may not include a conductive material. Of course, to further improve the charge conduction capability, the pressure-sensitive adhesive 5 between the display substrate 12 and the light-transmitting film 11 may also include a conductive material.

[0155] The present disclosure provides a method for preparing a display panel, wherein a transparent film is attached to the light-emitting side of a display substrate. The transparent film includes an antibacterial layer, which includes a transparent substrate and an antibacterial metal complex. The hydrophilic groups included in the transparent substrate can fully absorb water vapor in the air and on the surface of the film. The water vapor induces the antibacterial metal complex to release antibacterial metal ions, thereby achieving the effect of killing bacteria and viruses, preventing the residue and growth of bacteria and viruses on the surface of the transparent film, and preventing the transparent film surface from becoming a source of bacterial and viral contamination and further spread, thereby improving the antibacterial and viral resistance of the display panel. The transparent film also includes an anti-fingerprint layer to prevent stains and other residues, thereby improving the antibacterial effect. The anti-fingerprint layer has a contact angle greater than 100° and less than or equal to 150°, which can prevent stains from remaining while also preventing excessive contact angles that prevent water vapor from remaining and affecting the antibacterial performance.

When the light-transmitting film is attached to the display surface of a display product, the conductive material can guide accumulated charges on the display surface, thereby preventing charge accumulation. This can be particularly effective for touch-sensitive display products, preventing touch defects caused by charge accumulation.

[0174] In a specific implementation, a pressure-sensitive adhesive may be coated on the side of the polarizing functional layer facing away from the substrate during a roll-to-roll process.

[0175] When the light-transmitting film includes a polarizing functional layer, and when the polarizing functional layer includes a protective layer, a roll-to-roll process is used to bond the polarizing functional layer to the side of the substrate facing away from the antibacterial layer, and a pressure-sensitive adhesive is applied to the side of the polarizing functional layer facing away from the substrate. The specific steps are shown in FIG18 and include:

[0176] S301. Using a roll-to-roll process, the antibacterial substrate 9, the polarizing layer 301, and the protective layer 302 after the antibacterial layer is formed are laminated together using a roll-to-roll device 8 to obtain a light-transmitting film 11.

[0178] Alternatively, when the light-transmitting film includes a polarizing functional layer, and when the polarizing functional layer includes two protective layers, a roll-to-roll process is used to bond the polarizing functional layer to the side of the substrate facing away from the antibacterial layer, and to coat a pressure-sensitive adhesive on the side of the polarizing functional layer facing away from the substrate. The specific steps are shown in FIG19 and include:

[0179] S301: Using a roll-to-roll process, the antibacterial substrate 9 after forming the antibacterial layer and the polarizing functional layer 3 are laminated together using a roll-to-roll device 8 to obtain a light-transmitting film 11; wherein a pressure-sensitive adhesive 5 is also applied between the antibacterial substrate 9 and the polarizing functional layer 3;

[0181] In specific implementation, a release film is attached to one side of the pressure-sensitive adhesive to protect the transparent film coated with the pressure-sensitive adhesive. When the transparent film is attached to the light-emitting side of the display substrate, the release film needs to be torn off and then attached to the display substrate through the pressure-sensitive adhesive.
