DETAILED DESCRIPTION

[0027] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, the specific embodiments of the present application will be described below with reference to the drawings. Obviously, the drawings in the following description only represent some of the embodiments of the present application, and for those skilled in the art, other drawings can be obtained from these drawings without creative labor, and other embodiments can also be obtained.

[0028] In order to make the drawing simple, only the parts related to the application are shown in each drawing, which does not represent the actual structure of the product. In addition, in order to make the drawing simple and easy to understand, in some drawings, only one of the components with the same structure or function is shown schematically, or only one of them is marked. In this paper, "one" not only means "only one", but also means "more than one".

[0029] It should be further understood that the term "and / or" used in the present application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes these combinations.

[0030] In this paper, it should be noted that unless otherwise specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0031] In addition, in the description of the present application, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0032] For example, Figures 1-6The embodiment provides a display module 100, which comprises a display assembly 110 and a shielding layer 120, the display assembly 110 can display at least part of a preset complete target image, for example, an LED spliced display unit, the LED spliced display unit can be combined to form a complete image, each LED spliced display unit can display a corresponding part of the complete image, and the complete image is formed by combination, for example, a complete television display screen, and the embodiment is not limited to the television display screen.

[0033] Generally, the display module 100, especially the current LED spliced display unit, adopts a surface packaging technology, that is, an LED light emitting tube is directly installed on a bearing material (PCB or glass substrate), so that the rapidly changing high-frequency current emits electromagnetic waves into the air, and thus there is a corresponding electromagnetic leakage risk problem.

[0034] The application is to strengthen the electromagnetic shielding function of the display module 100, reduce the electromagnetic radiation of the display module 100 and the influence of external electromagnetic waves on the normal operation of the display module 100, and provide a display module 100 with a strengthened shielding function, so that better electromagnetic shielding effect can be achieved.

[0035] Therefore, some representative embodiments are given to facilitate clear understanding and implementation of the application, and the scope of the application is not limited to these representative embodiments.

[0036] A display module 100 comprises a display assembly 110 and a shielding layer 120, the display assembly 110 comprises a display area 111 and a non-display area 112, when the display assembly 110 is used for television imaging, the display assembly 110 is generally flat, the display area 111 is generally located on the flat surface of the display assembly 110, the flat surface generally has a large display imaging area, and it is convenient to face the observer to display the image, for example, the display assembly 110 is similar to a rectangle, the top surface and the bottom surface of the display assembly 110 are larger independent surfaces among six surfaces, the display area 111 can be preset on the top surface of the display assembly 110, and the other five surfaces are the non-display area 112, but the embodiment is not limited to this; in use, the display area 111 is generally placed in a vertical manner, so that the display area 111 is generally perpendicular to the ground, it is convenient for the observer to observe the display image generally parallel to the ground and perpendicular to the display area 111, and it is ensured that the observer can more accurately observe the display image with a preset shape.

[0037] Since the preset target image of the complete state generally has a large area, for example, the display screen display area 111 of the television has a large size, and the display area 111 of a single display component 110 cannot meet the display imaging requirement of a large size, and of course, it is not completely limited to the above reasons, therefore, a splicing method is generally used, that is, the display components 100 are spliced together, the display areas 111 of the plurality of display components 110 are coplanar, the display area 111 of each display component 110 displays a regional image of a corresponding region, and the plurality of corresponding regional images are spliced to present a complete preset target image, which can also be a preset target visual image information, and is not limited thereto.

[0038] The preset target visual information is complete image or image information corresponding to a complete image frame information at each moment based on specific requirements, and is not limited thereto. The display area 111 displays at least part of the preset target visual information, that is, the complete preset target visual information can be realized by splicing a plurality of display areas 111.

[0039] The shielding layer 120 has shielding properties, and can realize shielding effect in the area covered by the shielding layer 120. In some embodiments, the shielding layer 120 can be covered on the display area 111 and the non-display area 112. Since the non-display area 112 can not meet the requirement of covering the shielding layer 120 due to the layout space of electronic components and other functional components or other reasons, part of the area cannot be covered by the shielding layer 120, and therefore, at least part of the non-display area 112 is covered by the shielding layer 120, but it is not excluded that the non-display area 112 is completely covered. When the covering requirement is met, the non-display area 112 is covered as much as possible to ensure that the shielding effect of the display area 111 and the strengthening shielding effect of the non-display area 112 are realized at the same time, and the electromagnetic shielding effect of the entire display module 100 is realized. Since the display component 110 can be arranged at different positions by external force, the shielding layer 120 can always shield the electromagnetic field in the first space 140 where the display component 110 is located and the space outside the first space 140.

[0040] For "covering", it should be understood as the shielding of the first space 140 where the electromagnetic radiation source is located to the display area 111 and the non-display area 112, which can be full wrapping, and of course due to various conditions, it can also be non-full wrapping. Covering is not absolutely required to be in a manner of being attached to the surface of the display assembly 110, nor is it absolutely required to be attached to the surface of the electromagnetic radiation source device. The key point is to electromagnetically shield the first space 140 where the electromagnetic radiation source device is located from the space outside the first space 140, which is any possible area where the observer observes the preset visual information. The space outside the first space 140 can also be any area where other electromagnetic radiation sources outside the display module 100 are located. Therefore, under normal circumstances, the shielding layer 120 is directly attached to the surface of the display assembly 110 to achieve the effectiveness of the above shielding, and to minimize the impact on the disassembly and assembly work of the display assembly 110 and the normal display work of the display assembly 110, and is not limited thereto.

[0041] In some embodiments, the shielding layer 120 can be divided into a first shielding area 121 and a second shielding area 122, and the first shielding area 121 and the second shielding area 122 are in a separated state when not covering the display assembly 110, to facilitate the covering setting requirement of the surface of different positions of the display assembly 110, especially for the surface area of different orientation directions of the display assembly 110, the first shielding area 121 is used for covering and shielding the display area 111, and the second shielding area 122 is used for covering and shielding the non-display area 112, generally the display area 111 and the non-display area 112 are surface areas of different orientation directions, after the covering operation setting is completed, generally the first shielding area 121 and the second shielding area 122 are effectively connected and set, for example: the corresponding edges of the first shielding area 121 and the second shielding area 122 abut each other, or the corresponding edges of the first shielding area 121 and the second shielding area 122 are overlapped and set in the same area, which will increase the effective contact area of the first shielding area 121 and the second shielding area 122, ensure the stable conductive connection between the first shielding area 121 and the second shielding area 122, facilitate the grounding of the first shielding area 121 and / or the second shielding area 122, and realize the grounding of the entire shielding layer 120, increase the freedom of grounding installation position and mode, and also realize the full coverage of the display assembly 110, to avoid the joint between the first shielding area 121 and the second shielding area 122, which will cause electromagnetic leakage through the joint, in some corresponding embodiments, due to the limitation of the functional components such as electronic components in the non-display area 112, the second shielding area 122 does not necessarily need to cover all the areas of the non-display area 112, but needs to cover as much as possible of the non-display area 112 on the basis of meeting the display function of the display assembly 110, to strengthen the electromagnetic shielding effect of the non-display area 112 as much as possible, in other embodiments, it is not excluded that the area where the functional components such as electronic components are located in the non-display area 112 is covered by directly covering the electronic components with the shielding layer 120, to realize that the functional components such as electronic components are also contained in the first space 140, realize the electromagnetic shielding of the functional components, and further realize the better shielding effect of the display module 100.

[0042] In some embodiments, the first shielding area 121 and the second shielding area 122 are in a separated state in the uncovered installation condition, for example, the first shielding area 121 can be selected from a shielding film, which is generally preferred to have a high light transmittance, so that the light emitted by the display area 111 can be attenuated as little as possible when passing through the first shielding area 121, thereby improving the imaging quality of the display area 111. Therefore, in general, the film selected for the first shielding area 121 can be added with transparent conductive material, or the conductive wire layout in the film is relatively sparse, or the conductive wire size is relatively small, so that the light emitted by the display area 111 is pre-attenuated, that is, the attenuation is controlled within a pre-set range, which does not affect the imaging quality required by the design. Under the condition of meeting the above requirements, of course, the conductive wire size and the density of the plurality of conductive wire layouts will be as large as possible to improve the shielding effect. Since the film is generally selected from the materials of the prior art, it will not be described again. The light emitted by the display area 111 generally propagates in a pre-set direction to form an image, which is convenient for the observer to obtain pre-set visual information or part thereof, and is not limited thereto.

[0043] In some embodiments, the second shielding area 122 is at least partially structured to cover the first edge 1111 of the display area 111, so that the second shielding area 122 and the first shielding area 121 overlap at the first edge 1111 of the display area 111. Since the thickness of the display assembly 110 is generally relatively thin, the extension of the second shielding area 122 by the partial structure to cover the first edge 1111 will increase the coverage area of the second shielding area 122, and the second shielding area 122 will have a better coverage effect due to the different orientation directions of the covered area. For example, the second shielding area 122 is mainly adhered to the non-display area 112, and in this embodiment, the partial structure of the second shielding area 122 is extended to cover and adhere to the surface of the display area 111, thereby ensuring the adhesion between the second shielding area 122 and the display assembly 110. Since the second shielding area 122 is partially structured to extend and cover the first edge 1111 of the display area 111, the first edge 1111 is also covered by the first shielding area 121 at the first edge 1111. The first shielding area 121 and the second shielding area 122 will simultaneously cover the first edge 1111 at the first edge 1111, so that the first shielding area 121 and the second shielding area 122 have more overlapping contact surfaces, thereby ensuring that the first shielding area 121 and the second shielding area 122 maintain a continuous and stable electrical connection effect, and the different areas of the shielding layer 120 maintain a mutual conductive state.

[0044] In some embodiments, when grounding is required for the shielding layer 120, grounding of any one or more positions of the first shielding layer 120 and the second shielding layer 120 can achieve the overall grounding of the shielding layer 120.

[0045] In some preferred embodiments, since the partial structure of the second shielding area 122 extends away from the display area 111, the second shielding area 122 can be grounded at a position away from the display area 111, which facilitates the layout of grounding lines or other grounding conductive structures, and reduces the influence of grounding-related structures on the imaging of the display area 111.

[0046] In some other embodiments, a grounding member 130 is arranged on the side of the bearing layer 114 away from the display layer 113, and the grounding member 130 is electrically connected to the position of the extended edge of the second shielding area 122 away from the first shielding area 121, so as to achieve the grounding of the second shielding area 122 through the grounding member 130. Since the second shielding area 122 is electrically connected to the first shielding area 121, the grounding of the entire shielding area is achieved.

[0047] In some embodiments, the first shielding area 121 completely covers the side of the display layer 113 away from the bearing layer 114, i.e., the side is the display area 111, and the second shielding area 122 completely covers the side of the display layer 113 and the bearing layer 114, and the side of the display layer 113 and the bearing layer 114 is generally perpendicular to the surface of the display area 111, so that the first shielding area 121, the second shielding area 122 and the grounding member 130 are sequentially electrically connected and grounded. The "complete coverage" arrangement will better achieve the shielding effect of the display assembly 110.

[0048] In some embodiments, the display layer 113 is a display packaging structure, generally an LED packaging layer, that is, the LED chip and its related circuit can be protected and fixed in a layer of packaging material, and the LED packaging material generally includes epoxy resin, silicone, plastic, etc., which has good insulation, heat resistance and chemical stability, etc., for example: SMD, COB adopts surface packaging technology, and is not limited thereto. The carrier layer 114 is a circuit board or a glass substrate, and the packaged display layer 113 will be placed on the carrier layer 114 to form a display module 100 partially integrated structure, and the integrated structure of the display layer 113 and the carrier layer 114 is further covered by the shielding layer 120. Further, the shielding layer 120 includes a first shielding area 121 and a second shielding area 122, the first shielding area 121 is a first conductive film with preset light transmittance, and the second shielding area 122 is a second conductive film, which will make the first shielding area 121 and the second shielding area 122 be attached to the surface of the display assembly 110 in an attached manner, facilitating fast production operation, wherein the first shielding area 121 is a first conductive film with preset light transmittance, the purpose of preset light transmittance is to reduce the influence on the display imaging of the display area 111 as much as possible, of course, the basic requirement of electromagnetic shielding must be met, and the electromagnetic shielding effect and the display imaging effect are generally negatively correlated, in actual implementation, the implementer can determine the specific selection of the material with preset light transmittance based on the implementation requirements, but with the development of science and technology, there are more and more conductive materials with light transmittance, which will solve the problem of negative correlation between electromagnetic shielding effect and display imaging effect, therefore, the application also includes conductive films that meet the range of better electromagnetic shielding effect and display imaging effect, and is not limited thereto.

[0049] In some embodiments, the grounding member 130 is located at the side edge position of the carrier layer 114 away from the display layer 113, for example: when the side of the carrier layer 114 away from the display layer 113 is rectangular, the grounding member 130 will form a rectangular frame structure at the side edge position of the carrier layer 114, which can reduce the influence on the distribution of electronic components on the surface of the carrier layer 114, while ensuring effective grounding of the shielding layer 120 through the grounding member 130, and reducing the influence on the imaging of the display layer 113.

[0050] In some embodiments, the second conductive film is a non-light-transmitting material product, which can make the implementer select a material with lower cost, better conductive performance and electromagnetic shielding performance when selecting the second conductive film.

[0051] In some embodiments, the carrying layer 114 includes a functional area 1141 and a non-functional area 1142 on the side away from the display layer 113. The functional area 1141 can be understood as an area on the carrying layer 114 where functional components are assembled, such as an area where electronic components are assembled. The non-functional area 1142 is generally an idle area on the surface of the carrying layer 114. The non-functional area 1142 is generally located at the edge of the side of the carrying layer 114 away from the display layer 113 and the gap area between adjacent electronic components. The non-functional area 1142 on the carrying layer 114 is in a directly exposed state and is not shielded by functional components such as electronic components. In order to further improve the shielding effect of the side of the carrying layer 114 away from the display layer 113, for example, to enhance the shielding performance of the back of the television. In some embodiments, the non-functional area 1142 is fully covered by the grounding component 130 to maximize the electromagnetic shielding effect of the carrying layer 114 without affecting the normal installation of electronic components and the operation of electronic components.

[0052] In some embodiments, a display device (not shown in the drawings) is provided, for example, a television. The display device uses the display module 100 of the present application and further includes a back shell (not shown in the drawings). In order to achieve complete imaging and reduce the design size of a single display module 100, multiple display modules 100 are spliced together so that the corresponding sides of the multiple display modules 100 abut and the display areas 111 of the multiple display modules 100 are coplanar. However, it should be emphasized that the coplanar defined in the present application is not limited to coplanar. When the overall display device displays an imaging area that is a curved surface, for example, when the television screen is a curved surface, the display areas 111 of the multiple display modules 100 will collectively form a predetermined required curved surface. However, the multiple display modules 100 generally have a smooth transition, and the gap between the multiple display modules 100 needs to be as small as possible to reduce the impact on the overall imaging effect.

[0053] The back shell is generally made of metal material, which will make the back shell also have electromagnetic shielding function. In combination with the shielding layer 120, the display device will have better electromagnetic shielding performance.

[0054] In some embodiments, the back shell is provided with a first magnetic attraction component (not shown in the drawings), and the display module 100 is provided with a second magnetic attraction component (not shown in the drawings). The first magnetic attraction component and the corresponding second magnetic attraction component can be magnetically connected, which facilitates the quick splicing and assembly of the display module 100 in the back shell. The specific position, shape, and size of the first magnetic attraction component are not limited, as long as they facilitate splicing and installation.

[0055] The foregoing presents and describes the basic principles, main features and advantages of the present application. It should be understood by those skilled in the art that the present application is not limited to the above-described embodiments, and the above-described embodiments and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
