[0045] Figure 1 Schematic diagram of the cross-sectional structure of a display module in the prior art. Figure 1 As shown, the display module includes a polarizer 20 and a cover plate 30 sequentially stacked on one side of the display panel 10. As described in the background art, in order to achieve the effect of environmental integration, it is usually necessary to remove the polarizer 20 and the cover plate 30 in the existing display module structure and replace them with a structure consistent with the environment, such as a skin, etc. However, removing the polarizer 20 and the cover plate 30 will make the transmittance of the display module too large, and the reflectivity of the external light will also increase, resulting in a significant reduction in the contrast of the display module, which seriously affects the display effect of the display module.

[0046] In view of this, the present application provides a display panel, including a substrate, an isolation structure, a plurality of light-emitting devices, and at least one light-shielding structure. The isolation structure is located on one side of the substrate, and the isolation structure encloses a plurality of first openings and at least one second opening. The light-emitting device is located in the first opening, and the light-shielding structure is located in the second opening.

[0047] By setting a shading structure between the light-emitting devices, the reflectivity of the display module of the depolarizer is reduced, and the problem of increased reflection of external light is improved, thereby improving the contrast of the display module and achieving the purpose of improving the display effect of the environmental integrated display module.

[0048] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. In the following detailed description, many specific details are proposed to provide a comprehensive understanding of the present application. However, it is obvious to those skilled in the art that the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating examples of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application. The features and exemplary embodiments of various aspects of the present application will be described in detail below.

[0049] Figure 2 FIG. 1 is a schematic diagram of a cross-sectional structure of a display panel in an embodiment of the present application. Figure 2 As shown, the display panel includes a substrate 100 and an isolation structure 200 located on one side of the substrate 100, wherein the isolation structure 200 encloses a plurality of first openings 210 and at least one second opening 220. The light emitting device 300 of the display panel is located in the first opening 210, and a light shielding structure 400 is disposed in the second opening.

[0050] This embodiment blocks and absorbs external light by setting a shading structure 400 between the light-emitting devices 300, thereby preventing external light from entering the display module and reducing the reflectivity of the display module without the polarizer. The inventor has verified through experiments that the display panel provided by this embodiment has a reflectivity drop of about 20% compared to a conventional display panel (i.e., the display panel does not include the shading structure 400). In this case, when the display panel provided by this embodiment is applied to an environment-integrated display module, the reflectivity increase problem of ambient light caused by removing the polarizer 20 can be improved, and the viewing angle and contrast of the display module can be prevented from being affected by ambient light, thereby improving the contrast of the display module and achieving the purpose of improving the display effect of the environment-integrated display module.

[0051] In one embodiment, the isolation structure 200 isolates each light emitting device 300 to prevent unnecessary flow or leakage of electrons between different pixels or regions, thereby helping to maintain the independence of pixels and prevent crosstalk between pixels. Exemplarily, the isolation structure 200 includes a pixel definition layer.

[0052] In one embodiment, the display panel further includes a support layer 500, which is located on the side of the isolation structure 200 away from the substrate 100, and is used to provide support to ensure that the mask plate and the first opening 210 in the process can be accurately aligned and positioned. Exemplarily, the support layer 500 includes a plurality of support pillars.

[0053] In one embodiment, the light shielding structure 400 includes a light shielding material layer, which blocks and absorbs external light, thereby reducing the light transmittance of the display module behind the depolarizer 20 and improving the problem of increased external light reflection.

[0054] In one embodiment, the material of the light-shielding material layer may include any one of black glue, yellow glue, and gray glue. The light-shielding principle of the light-shielding material layer is mainly to reduce or completely block the entry of light by absorbing or reflecting light. The density and color of the light-shielding material layer determine its shielding effect. The higher the density, the better the shielding effect; the darker the color, the more light is absorbed and reflected.

[0055] In one embodiment, the display panel further includes a first inorganic encapsulation layer 600, which is stacked on the side of the light emitting device 300 away from the substrate 100 and is stacked between the light shielding structure 400 and the substrate 100. Figure 2 In this embodiment, by providing the first inorganic encapsulation layer 600 between the light shielding structure 400 and the substrate 100, it is possible to avoid water and oxygen from entering the light shielding structure 400 during the preparation process, thereby damaging the light emitting device 300 and affecting the display effect of the display panel.

[0056] In one embodiment, the display panel further includes an organic encapsulation layer 700 and a second inorganic encapsulation layer 800, wherein the organic encapsulation layer 700 is stacked on the first inorganic encapsulation layer 600 and the light shielding structure 400 on the side away from the substrate 100, and the second inorganic encapsulation layer 800 is located on the side of the organic encapsulation layer 700 away from the substrate 100. The organic encapsulation layer 700 can be manufactured by coating or inkjet printing process to play a flattening role, and the second inorganic encapsulation layer 800 plays a role in blocking external water and ions.

[0057] Figure 3 FIG. 1 is a top view of a display panel in another embodiment of the present application. Figure 3 As shown, the isolation structure 200 encloses a plurality of first openings 210, each of which is provided with a light emitting device 300, and a plurality of second openings 220 are provided around the first openings 210, and the plurality of second openings 220 are arranged at intervals around the first openings 210. A light shielding structure 400 is provided in the second opening, and the light shielding structure 400 corresponds to the second openings 220 one by one.

[0058] By evenly arranging the shading structure 400 between the light-emitting devices 300, this embodiment can effectively absorb or block the light passing through the display module, thereby effectively reducing the reflectivity of the display module of the depolarizer, improving the problem of increased reflection of external light, and effectively improving the contrast of the display module, thereby achieving the purpose of improving the display effect of the environmentally integrated display module.

[0059] The arrangement and quantity of the second openings 220 can be set according to requirements.

[0060] In one embodiment, the number of the second openings 220 and the number of the first openings 210 may be equal, that is, the number of the light shielding structures 400 and the number of the light emitting devices 300 are equal.

[0061] In one embodiment, the number of the second openings 220 may be smaller than or greater than the number of the first openings 210 , that is, the number of the light shielding structures 400 may be smaller than or greater than the number of the light emitting devices 300 .

[0062] Figure 4 FIG. 1 is a top view of a display panel in another embodiment of the present application. Figure 3 compared to, Figure 4 The second opening 220 shown has a different shape. Figure 3 The second opening 220 is in a rectangular shape. Figure 4 The shape of the second opening 220 is an ellipse. In order to make the light shielding structure 400 shield and absorb more transmitted light, its light receiving area needs to be increased as much as possible. Therefore, in order to make the most of the space in the display panel, the shape of the second opening 220 can be set to match the shape of the space in the display panel.

[0063] However, the above is not a limitation on the shape of the second opening 220 in the present application. The shape of the second opening 220 in the present application may include polygonal, circular, annular, frame-shaped, etc. In some embodiments, there may be multiple second openings 220 of different shapes in the same display panel, and the area sizes of different second openings 220 may also be different.

[0064] In one embodiment, the plurality of light-emitting devices 300 include light-emitting device units that can emit multiple colors, for example, a red light-emitting device R, a green light-emitting device G, and a blue light-emitting device B, which are arranged according to a certain pixel layout design to meet different resolution requirements.

[0065] Figure 5 FIG. 1 is a top view of a display panel in another embodiment of the present application. Figure 5 As shown, the display panel includes a second opening 220 , and the orthographic projection of the second opening 220 on the substrate surrounds the orthographic projections of the plurality of first openings 210 on the substrate.

[0066] In the present embodiment, by setting a second opening, the position outside the first opening 210 can be more effectively utilized, and the area of ​​the shading structure can be increased, so as to absorb or block more transmitted light, further reduce the emissivity of the display module of the depolarizer, improve the problem of increased reflection of external light, and effectively improve the contrast of the display module, thereby achieving the purpose of improving the display effect of the environmental integrated display module.

[0067] Figure 6 FIG. 2 is a schematic diagram of a cross-sectional structure of a display panel in another embodiment of the present application. Figure 6 As shown, the light shielding structure 400 includes a photoelectric conversion device, which includes a first electrode 410, a photoelectric conversion unit 420 and a second electrode 430 sequentially stacked on the substrate 100. The light emitting device 300 includes a third pixel electrode 310, a light emitting unit 320 and a fourth common electrode 330 sequentially stacked on the substrate 100.

[0068] In one embodiment, the second electrode 430 and the fourth common electrode 330 are disposed in the same layer.

[0069] In one embodiment, the electrode layer where the second electrode 430 and the fourth common electrode 330 are located is a cathode layer.

[0070] In one embodiment, the isolation structure 200 may include a conductive material, so that the fourth common electrodes 330 located between the isolation structures 200 can be connected to each other through the isolation structure 200 to form a whole surface electrode, and the interconnection reduces power consumption. In addition, the third pixel electrode 310 and the isolation structure 200 are insulated to avoid short circuit between the third pixel electrode 310 and the fourth common electrode 330 of the light emitting device 300.

[0071] Figure 7 for Figure 6 A schematic diagram of the structure of the photoelectric conversion unit is shown in FIG. Figure 7 As shown, the photoelectric conversion unit 420 includes a first semiconductor layer 421 and a second semiconductor layer 422 stacked together. The first semiconductor layer 421 and the second semiconductor layer 422 are used to form a heterojunction. The first electrode 410 is coupled to the first semiconductor layer 421 , and the second electrode 430 is coupled to the second semiconductor layer 422 .

[0072] In one embodiment, the first semiconductor layer 421 may be an interlayer structure composed of a P-type semiconductor material that provides holes during the photoelectric conversion process. The second semiconductor layer 422 may be an interlayer structure composed of an N-type semiconductor material that provides electrons during the photoelectric conversion process. In this way, the first semiconductor layer 421 and the second semiconductor layer 422 of different conductivity types form a PN junction, i.e., a heterojunction. When the photoelectric conversion unit 420 is illuminated, photons carrying energy enter the PN junction and generate electron-hole pairs, i.e., photogenerated carriers. When a voltage is applied to the first electrode 410 and the second electrode 430, the photogenerated carriers drift to form a current. The greater the intensity of the light, the greater the current.

[0073] The embodiment of the present application uses the photoelectric conversion device as a shading structure 400 and sets it in the second opening 220. It can absorb external light and reduce the transmittance of the display module while converting light energy into electrical energy for storage. It is suitable for application scenarios such as on-board displays of rechargeable cars and is used to increase the endurance of vehicles, etc.

[0074] In some other embodiments, the photoelectric conversion unit 420 further includes a third semiconductor layer 423. The third semiconductor layer 423 is located between the first semiconductor layer 421 and the second semiconductor layer 422. The third semiconductor layer 423 is used to increase the width of the depletion region in the heterojunction.

[0075] In one embodiment, the third semiconductor layer 423 may be an interlayer structure formed of an intrinsic semiconductor material.

[0076] It can be understood that the introduction of the third semiconductor layer 423 increases the thickness of the depletion region, which is conducive to shortening the diffusion process of carriers. The widening of the depletion layer can also significantly reduce the junction capacitance, thereby reducing the circuit constant. At the same time, the widening of the depletion layer is also conducive to the absorption of long-wavelength light.

[0077] Figure 8 FIG. 2 is a schematic diagram of a cross-sectional structure of a display panel in another embodiment of the present application. Figure 8 As shown, the difference between the display panel provided in this embodiment and the display panel provided in any of the above embodiments is that, in this embodiment, the display panel further includes a pixel circuit 900, which is located between the substrate 100 and the light-emitting device 300. Exemplarily, the pixel circuit 900 may be a 7T1C pixel circuit, an 8T1C pixel circuit, etc. The pixel circuit 900 includes a capacitor C, and the orthographic projection of the capacitor C on the substrate 100 overlaps with the orthographic projection of the light-shielding structure 400 on the substrate 100.

[0078] The present application also provides a method for preparing a display panel, such as Fig. 9 shown. Fig. 9 This is a process flow chart of a method for preparing a display panel in an embodiment of the present application, and the specific steps are described as follows.

[0079] S810: preparing an isolation structure on a substrate, wherein the isolation structure encloses a plurality of first openings and at least one second opening.

[0080] S820: Prepare a light-emitting device in the first opening.

[0081] S830: preparing a light shielding structure in the second opening.

[0082] S840: preparing a packaging structure on the side of the light-emitting device facing away from the substrate to obtain a display panel.

[0083] In one embodiment, the encapsulation structure includes a first inorganic encapsulation layer. A light shielding structure is prepared in the second opening, and the encapsulation structure is prepared on a side of the light emitting device away from the substrate, including:

[0084] A first inorganic encapsulation layer is prepared on a side of the light-emitting device facing away from the substrate, wherein the first inorganic encapsulation layer covers a surface of the second opening facing away from the substrate;

[0085] A light shielding structure is prepared in the second opening.

[0086] In one embodiment, the light shielding structure includes a light shielding material layer. Exemplarily, first, a coating process is used to coat the light shielding material layer on the side of the first inorganic encapsulation layer away from the substrate; second, the mask plate and the display panel are aligned; then, the light shielding material layer is patterned by exposure and development processes; finally, the light shielding material layer is baked to obtain the light shielding structure.

[0087] In one embodiment, the encapsulation structure further includes an organic encapsulation layer and a second inorganic encapsulation layer; and the preparation method further includes:

[0088] An organic encapsulation layer is prepared on the side of the first inorganic encapsulation layer and the light shielding structure facing away from the substrate;

[0089] A second inorganic encapsulation layer is prepared on the side of the organic encapsulation layer facing away from the substrate.

[0090] The present application also provides a display module, comprising any of the above display panels, such as Fig.10 shown. Fig.10 It is a schematic diagram of the cross-sectional structure of a display module in yet another embodiment of the present application. Fig.10 The display module shown also includes an encapsulation structure and a skin 40 covering the light emitting device 300 and the light shielding structure 400 on the side away from the substrate 100, and the skin 40 is located on the side of the encapsulation structure away from the substrate 100. The encapsulation structure includes a first inorganic encapsulation layer 600, an organic encapsulation layer 700, and a second inorganic encapsulation layer 800 sequentially stacked on the side of the substrate close to the light emitting device 300.

[0091] Since the display module in this embodiment uses a display panel 10 with low transmittance, although the polarizer 20 and cover plate 30 commonly used in the traditional display module are removed, the reflectivity of the display module equipped with the skin 40 can still be effectively reduced, so that the display module can have a higher contrast and improve the display effect. In addition, by removing the polarizer 20 and cover plate 30 and adding the skin 40, the thickness of the display module is effectively reduced, and the thickness of the entire display module can be controlled within 1 mm.

[0092] In one embodiment, the display module further includes an optical adhesive layer 50 located between the packaging structure and the skin 40, for attaching the skin 40. It can be seen that the display module is not provided with a polarizer and a cover plate.

[0093] In one embodiment, the thickness of the display module is greater than or equal to 0.7 mm and less than or equal to 0.94 mm. The thickness of the display module refers to the sum of the thickness of the display panel and the thickness of at least one functional film layer located on the non-light-emitting side of the display panel. The at least one functional film layer mentioned here, for example, includes a pressure-sensitive adhesive (PSA) layer, a support film (Bottom Protect Film, BPF) and a composite tape (Standard Cubic Feet, SCF) sequentially stacked on the non-light-emitting side of the display panel. Exemplarily, the thickness of the display module is 0.7 mm, 0.8 mm, 0.85 mm, 0.9 mm or 0.94 mm, etc.

[0094] In one embodiment, the surface 40 includes any one of wood grain, leather, and fabric. The choice of the surface mainly depends on the application scenario of the display module. For example, the interior surface of a vehicle, of course, it can also be the interior surface of an airplane, a ship, etc., and it can also be the decorative surface inside or outside a building, such as the decorative surface in a shopping mall, and the decorative surface of a household appliance.

[0095] In one embodiment, the transmittance of the epidermis 40 is 20%-55%, and the light emitted by the light emitting device 300 penetrates the epidermis 40, realizing environmental integration in the non-display stage of the display module, and simple lines and low-resolution display images in the display stage.

[0096] In one embodiment, the surface 40 includes but is not limited to a diffuse reflective matte surface, a reflective bright surface, etc., which can be selected according to the application scenario requirements.

[0097] In one embodiment, the material of the skin 40 includes but is not limited to polyethylene terephthalate (PET), acrylonitrile butadiene styrene (ABS), polymethyl methacrylate (PMMA), silicone, and the like.

[0098] In one embodiment, the substrate 100 includes alternately stacked fiber material layers and resin material layers. In this embodiment, the fiber material layers and resin material layers are used to replace the original glass substrate, and the cover plate 30 of the display module is removed, so that the entire module does not contain a glass structure, thereby improving the safety of the display module.

[0099] In one embodiment, the material of the fiber material layer includes at least one of polyphenylsulfone terephthalamide fibers and chopped carbon fibers.

[0100] In one embodiment, the material of the resin material layer includes bisphenol F epoxy resin.

[0101] The present application also provides an intelligent display system, including any of the display modules described above. An intelligent display system generally refers to a highly integrated and intelligent display system that can achieve more efficient data processing and image rendering through built-in chips and algorithms, and provide a more streamlined and realistic visual experience.

[0102] In one embodiment, the smart display system includes a smart home system, including household appliances such as refrigerators and televisions with display modules. By replacing the polarizer 20 and the cover plate 30 with the epidermis 40 in the display module, and providing a shading structure 400 on the same layer as the light-emitting device, the display module can achieve a good display effect integrated with the environment. For example, when the TV is turned off, it is no longer a large area of ​​black, but a decorative layer that is harmonious with the indoor decoration style, such as a display effect of original wood grain.

[0103] In one embodiment, the intelligent display system includes an intelligent cockpit system, including electronic devices with display modules such as navigators. Compared with the smart home system, in addition to integrating the skin 40 to achieve an integrated display effect of the environment, a photoelectric conversion device can be further integrated as a shading structure. While ensuring the display contrast of the display module, the natural light resources outside the cockpit can be effectively utilized and converted into electrical energy, which is stored in the battery and other electrical energy storage components of the intelligent cockpit system, thereby achieving the effect of extending the battery life of the intelligent cockpit system.
