Description

Technical Field

[0001] Embodiments of the present disclosure relate to a display module, a spliced ​​screen and a display device. Background Art

[0002] The application of display devices formed by spliced ​​screens is becoming more and more widespread, and each spliced ​​screen is usually formed by splicing multiple independent display modules. The application scenarios of display devices formed by spliced ​​screens mainly include areas that require large-area displays, such as conference rooms, halls, and monitoring centers. Each display module usually includes a display component and a backlight component. The middle frame included in the backlight component is arranged on one side of the display component. The middle frame is provided with a bearing platform that can bear the display component, and a receiving area that can accommodate optical films such as light guide plates, diffusers, and reflective structures. The reflectivity of the reflective structure to light will directly affect the display brightness of the display device and whether there are alternating light and dark stripes around the display device when displaying. The bearing platform needs to be connected and fixed to the non-display area of ​​the display component by adhesive, and the back panel included in the backlight component can support the middle frame.

[0065] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0066] Unless otherwise defined, the technical terms or scientific terms used in the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs. The "first", "second" and similar words used in the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0067] Unless otherwise defined, the features such as "parallel", "perpendicular" and "same" used in the embodiments of the present invention include the situations of "parallel", "perpendicular", "same" in a strict sense, as well as the situations of "approximately parallel", "approximately perpendicular", "approximately the same", etc., which contain certain errors. For example, the above-mentioned "approximately" may mean that the difference of the compared objects is within 10% or 5% of the average value of the compared objects. When the number of a component or element is not specifically indicated in the following text of the embodiments of the present invention, it means that the component or element may be one or more, or may be understood as at least one. "At least one" refers to one or more, and "multiple" refers to at least two. The "same-layer arrangement" in the embodiments of the present invention refers to the relationship between multiple film layers formed by the same material after the same step (for example, a one-step patterning process). The "same layer" here does not always mean that the thickness of multiple film layers is the same or the height of multiple film layers in the cross-sectional view is the same.

[0068] For display devices, display quality is one of the important parameters for evaluating the display effect of the display device, especially for mid-to-high-end display devices formed by splicing screens. After the splicing screen is formed by splicing multiple display modules, there are differences in the display quality of individual display modules, which makes the overall visual effect of the splicing screen very poor, and the phenomenon of alternating light and dark stripes around the display device is very obvious when the display device is displaying. For example, in the splicing screen technology, the splicing screen is formed by splicing multiple display modules, and the middle frame included in each display module can be a middle frame formed by plastic or a middle frame formed by transparent aluminum metal. After the splicing screen is used for a long time or under high temperature, the middle frame formed by plastic material is easily oxidized and its color becomes darker, which will cause the light transmittance of the middle frame to decrease, so that the peripheral brightness of the final display device is reduced, and the phenomenon of peripheral dark frame appears. The middle frame formed by aluminum metal also has the problem of uneven brightness of the periphery and the middle area. The size of the physical seam between adjacent display modules is an important physical parameter for the quality of the spliced ​​screen. In order to make the seam between adjacent display modules as small as possible, glue is usually used to connect the adjacent display modules. The main component of the glue is a transparent resin material. The glue is easily oxidized after long-term use, causing the color to deepen, and the light transmittance of the glue will also be weakened, resulting in dark edge pixels on the display device during display, and also causing the seam between adjacent display modules to become larger.

[0069] At present, the application scenarios of splicing screens mainly include conference rooms, halls and monitoring centers. The display devices formed by splicing screens usually have high brightness, and the temperature of the display devices is also high during use. The large temperature difference when the display device is in a working state and a non-working state is likely to cause the gap between adjacent structures such as the diffusion plate included in the display module to change, thereby causing the light transmittance of the edge of the display device to change, and then the display device will have bright lines or dark lines or light stripes and dark stripes alternating in sequence when displaying, that is, the phenomenon of alternating light and dark stripes occurs, which makes the display effect of the display device worse. The poor display effect of the above-mentioned display devices is caused by the material properties of the adhesive. The current display devices cannot solve the above problems and can only be solved by disassembling and repairing the display devices or replacing them. However, the cost of repairing the display devices is very high and will seriously affect the brand reputation and brand image of the display devices. Therefore, it is necessary to improve the structure of the current display devices to enhance the market competitiveness of the display devices.

[0070] The inventors of the present disclosure have noticed that it is possible to start with the design architecture of the display module. For example, the reflectivity of the reflective structure or the reflectivity of the reflective glue can be adjusted in a targeted manner according to the surrounding image quality when the display device is displaying. That is, a new structural design can be made for the reflective structure or the reflective glue, so that the image quality uniformity of the display device reaches a higher level. Without disassembling the display device, the peripheral image quality of the display module included in the display device can be adjusted, and the maintenance rate of the display device during the production process and the maintenance rate of the terminal product can be greatly reduced, thereby reducing the maintenance cost of the display device to enhance the competitiveness of the display device. For display devices with high-standard image quality requirements, it is impossible to develop new display products independently, and it is impossible to select suitable display products through testing, which will cause market losses.

[0071] At least one embodiment of the present disclosure provides a display module, which includes: a backlight assembly, which includes a middle frame, a reflective structure and a light source structure, the light source structure includes a light source part and a support plate that carries the light source part; the reflective structure includes a first part parallel to a first plane where the support plate is located, and a second part on a second plane intersecting the first plane, the second part is connected to the middle frame, and the first part is connected to the support plate, and the reflective structure is configured to reflect light emitted by the light source part; the second part of the reflective structure includes a first reflective sheet, a second reflective sheet and a third reflective sheet that are stacked, the main part of the second reflective sheet is arranged in a accommodating space defined by the first reflective sheet and the third reflective sheet, and the main part of the second reflective sheet can be moved relative to the first reflective sheet, the middle part of the first reflective sheet is provided with a first opening, the surface of the second reflective sheet facing the first reflective sheet has at least one first light adjustment pattern, and the main part of the second reflective sheet moves relative to the first reflective sheet so that the overlapping area of ​​the first opening and the first light adjustment pattern changes. In the embodiment of the present disclosure, the second part of the reflective structure is designed to include a first reflective sheet, a second reflective sheet and a third reflective sheet which are stacked, and a first opening is provided in the middle part of the first reflective sheet, and a surface of the second reflective sheet facing the first reflective sheet has at least one first light adjustment pattern. When the user is using the display device, if dark lines, bright lines or dark frames appear on the edge of the display device, the main body of the second reflective sheet can be moved relative to the first reflective sheet without disassembling the display device, so that the overlapping area of ​​the first opening and the first light adjustment pattern changes, thereby changing the amount of reflected light to adjust the peripheral image quality of the display device, thereby greatly reducing the probability of repairing the display device during the production process and reducing the maintenance rate of the display device of the terminal, thereby reducing the maintenance cost of the display device as a whole to enhance the competitiveness of the display device.

[0072] For example, Figure 1 A schematic cross-sectional structure diagram of a display module provided in at least one embodiment of the present disclosure is shown in FIG. Figure 2 for Figure 1 A partially enlarged schematic diagram of the reflection structure. Figure 3 The schematic diagram of the overall planar structure of the first reflector provided in at least one embodiment of the present disclosure is as follows. Figure 4 for Figure 3 A partial enlarged structural diagram of the first reflector, Figure 5 A schematic diagram of the planar structure of a second reflector provided in at least one embodiment of the present disclosure, Figure 6 for Figure 5 A partial enlarged structural diagram of the second reflector in FIG. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the display module 10 includes: a backlight assembly 101, the backlight assembly 101 includes a middle frame 102, a reflective structure 103 and a light source structure 104, the light source structure 104 includes a light source unit 105 and a support plate 106 carrying the light source unit 105; the reflective structure 103 includes a first portion 1031 parallel to a first plane where the support plate 106 is located, and a second portion 1032 on a second plane intersecting the first plane, the first portion 1031 of the reflective structure 103 is connected to the second portion 1032, the second portion 1032 is connected to the middle frame 102, and the first portion 1031 is connected to the support plate 106. The board 106 is connected, and the reflective structure 103 is configured to reflect the light emitted by the light source part 105; the second part 1032 of the reflective structure 103 includes a first reflective sheet 1033, a second reflective sheet 1034 and a third reflective sheet 1035 which are stacked, and the main part 1034a of the second reflective sheet 1034 is arranged in the accommodation space defined by the first reflective sheet 1033 and the third reflective sheet 1035, and the main part 1034a of the second reflective sheet 1034 can move relative to the first reflective sheet 1033 in the accommodation space defined by the first reflective sheet 1033 and the third reflective sheet 1035. For example, the main part 1034a of the second reflector 1034 can move linearly on a straight line relative to the first reflector 1033, or can also translate on a plane. The middle part of the first reflector 1033 is provided with a first opening 1036, and the surface of the second reflector 1034 facing the first reflector 1033 has at least one first light adjustment pattern 1037. The main part 1034a of the second reflector 1034 can move relative to the first reflector 1033 so that the overlapping area of ​​the first opening 1036 and the first light adjustment pattern 1037 changes. In the embodiment of the present disclosure, the second part 1032 of the reflective structure 103 is designed to include a first reflective sheet 1033, a second reflective sheet 1034, and a third reflective sheet 1035 which are stacked, and a first opening 1036 is provided in the middle part of the first reflective sheet 1033, and a surface of the second reflective sheet 1034 facing the first reflective sheet 1033 has at least one first light adjustment pattern 1037. When a user uses the display device, if the display device has problems such as dark lines, bright lines, or dark frames on the edges, the display device can be easily adjusted without disassembling the final display device. In this case, by making the main part 1034a of the second reflective sheet 1034 move relative to the first reflective sheet 1033 so that the overlapping area of ​​the first opening 1036 and the first light adjustment pattern 1037 changes, the amount of light reflected by the reflective structure 103 can be changed to adjust the peripheral image quality of the display device, thereby greatly reducing the probability of repairing the display device during the production process and reducing the probability of repairing the display device of the terminal, thereby reducing the overall cost of repairing the display device and improving the competitiveness of the display device.

[0073] It should be noted that although Figure 1 and Figure 2 Not shown in the figure, in addition to the main body, the second reflective sheet also has handle parts arranged at the two ends of the main body. For example, the handle part is a part extending from the left and right ends of the main body respectively. The user of the terminal product can drive the main body of the second reflective sheet to move relative to the first reflective sheet within the accommodation space defined by the first reflective sheet and the third reflective sheet by holding the handle part, so as to adjust the peripheral image quality of the display device without disassembling the display device, so as to reduce the phenomenon of dark frames and dark lines or bright lines on the edges. The handle part is described in more detail in the following embodiments.

[0074] For example, in one example, only the first reflective sheet 1033 may be in contact with the middle frame 102, and neither the second reflective sheet 1034 nor the third reflective sheet 1035 may be in contact with the middle frame 102; for example, in another example, Figure 1 As shown, the first reflective sheet 1033 and the third reflective sheet 1035 may both be in contact with the middle frame 102 , while the second reflective sheet 1034 is not in contact with the middle frame 102 , which is not limited in the embodiments of the present disclosure.

[0075] For example, Figure 1 and Figure 2 As shown, the first reflector 1033 and the third reflector 1035 are glued and fixed at the peripheral position, and the cross-section of the third reflector 1035 includes a bent portion, so that a cavity can be formed after the first reflector 1033 and the third reflector 1035 are glued at the peripheral position. For example, the first reflector 1033 and the third reflector 1035 are connected between surfaces at the peripheral position, so that the connection between the first reflector 1033 and the third reflector 1035 is more stable. The second reflector 1034 is arranged in the cavity, and the second reflector 1034 does not contact the surface of the first reflector 1033 and the surface of the third reflector 1035, so as to ensure that the second reflector 1034 can move freely relative to the first reflector 1033.

[0076] In the embodiments of the present disclosure, a reflective structure is designed to have a three-layer stacked structure of a first reflective sheet 1033, a second reflective sheet 1034 and a third reflective sheet 1035, and the second reflective sheet 1034 is located in a cavity formed by the first reflective sheet 1033 and the third reflective sheet 1035. The second reflective sheet 1034 is moved relative to the first reflective sheet 1033 to adjust the overlapping area between the first opening 1036 in the first reflective sheet 1033 and the first light adjustment pattern 1037 in the second reflective sheet 1034, thereby changing the reflectivity of the reflective structure to light, so as to reduce the problem of dark frames or dark lines or bright lines on the edges, thereby adjusting the peripheral image quality of the display device without disassembling the final display device.

[0077] For example, Figure 1 and Figure 2 As shown, the second portion 1032 of the reflective structure 103 is tilted relative to the first portion 1031, and the dihedral angle formed by the first plane where the first portion 1031 is located and the second plane where the second portion 1032 is located is in the range of (90°, 180°), that is, Figure 1 It can be seen from the figure that the angle α is an obtuse angle. The angle α being an obtuse angle can be more conducive to the light emitted by the light source structure to reach the display component, so as to enhance the display effect.

[0078] It should be noted that the “inclined setting” in which the second part 1032 of the reflective structure 103 is inclined relative to the first part 1031 does not include the situation where the second part 1032 is vertically set relative to the first part 1031. When the second part 1032 of the reflective structure 103 is vertically set relative to the first part 1031, the coverage range of the light emitted from the reflective structure will be very small, which will affect the final display effect of the display device.

[0079] For example, Figure 1 and Figure 2 As shown, the first part 1031 is a single-layer structure, and the first part 1031 and the second part 1032 include a first reflector 1033 integrally formed to form a bending structure, in which the first part 1031 is horizontally arranged, and the first part 1031 is in direct contact with the support plate 106, so that the contact area between the reflective structure 103 and the support plate 106 can be larger, and the first part 1031 supports the second part 1032, so that the first reflector 1033 can be stably arranged to be more firmly connected to the middle frame 102. For example, in combination with Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the fourth sides of the third reflector 1035 are in surface contact with the first reflector 1033, and the first reflector 1033 and the third reflector 1035 are fixedly connected to form a fixed accommodating space. The fourth sides of the third reflector 1035 and the surface of the first reflector 1033 are in surface contact, that is, the surface-to-surface contact and fixation make the connection between the first reflector 1033 and the third reflector 1035 more stable.

[0080] For example, Figure 3 and Figure 4 As shown, the peripheral portion of the first reflector 1033 and the third reflector 1035 that are in contact with each other are provided with a second opening 1038, and the size of the second opening 1038 is smaller than the size of the first opening 1036. The second opening 1038 is provided in the peripheral portion of the first reflector 1033 so that the reflectivity of light can be adjusted by the first reflector 1033, that is, a portion of the light incident on the second opening 1038 can directly reach the third reflector 1035, and the material of the third reflector 1035 can be a metal material with light absorption ability; or the material of the first reflector 1033 can be a metal material with light absorption ability, and the third reflector 1035 can reflect the light incident thereon, that is, a portion of the light incident on the second opening 1038 can directly reach the third reflector 1035, and the third reflector 1035 reflects the light incident thereon.

[0081] For example, the amount of light incident on the middle area of ​​the first reflector is generally greater than the amount of light incident on the peripheral area of ​​the first reflector. Figure 3 and Figure 4 As shown, the planar shapes of the first opening 1036 and the second opening 1038 are both circular, and the size of the first opening 1036 is 2 to 6 times the size of the second opening 1038. For example, the size of the first opening 1036 is 2, 3, 4, 5 or 6 times the size of the second opening 1038. This can make the light adjustment ability in the middle area of ​​the first reflector 1033 stronger to adapt to the situation where more light is irradiated to the middle area of ​​the middle area of ​​the first reflector 1033.

[0082] For example, Figure 3 and Figure 4 As shown, the arrangement density of the second openings 1038 is greater than the arrangement density of the first openings 1036, that is, within the same area, the number of the second openings 1038 is greater than the number of the first openings 1036, so that the second openings 1038 can adjust the light more precisely.

[0083] For example, in other examples, the farther away from the center of the first reflector 1033, the smaller the density of the first openings 1036 in the middle area of ​​the first reflector 1033, that is, the density of the first openings 1036 in the middle area of ​​the first reflector 1033 changes gradually; or the farther away from the center of the first reflector 1033, the smaller the size of the first openings 1036 in the middle area of ​​the first reflector 1033, that is, the size of the first openings 1036 in the middle area of ​​the first reflector 1033 changes gradually.

[0084] It should be noted that the planar shape of the second opening 1038 can be circular, rectangular, or other regular or irregular shapes.

[0085] For example, combined with Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown in the schematic structural diagram, the number of the first openings 1036 and the first light adjustment patterns 1037 are the same and are both multiple, the shape of each first light adjustment pattern 1037 is the same as the shape of the first opening 1036, and the first light adjustment patterns 1037 and the first openings 1036 correspond one to one, so that the amount of reflected light can be adjusted by the first light adjustment patterns 1037 and the first openings 1036.

[0086] For example, Figure 5 and Figure 6 As shown, the first light adjustment pattern 1037 on the second reflector 1034 is a printed dot pattern that can absorb light, and the size, distribution position and arrangement of the dot pattern are the same as the size, distribution position and arrangement of the first opening 1036 in the middle area of ​​the first reflector 1033. In this way, the first light adjustment pattern 1037 and the first opening 1036 can more finely adjust the amount of light reflected.

[0087] For example, Figure 5 and Figure 6 As shown, the first light adjustment pattern 1037 includes black dots. Of course, the embodiments of the present disclosure are not limited thereto, and may also be regular shapes such as black rectangles or irregular shapes. The color of the first light adjustment pattern 1037 may also be other colors that can absorb light other than black, such as brown, dark blue, etc., which are not limited in the embodiments of the present disclosure.

[0088] For example, Figure 5 and Figure 6 As shown, the second reflective sheet 1034 further includes a handle portion 1034b disposed at at least one end of the main body portion 1034a. Figure 5 and Figure 6In the embodiment, the second reflective sheet 1034 further includes handle portions 1034 b respectively disposed at two ends of the main body portion 1034 a , and the handle portions 1034 b extend out of the accommodation space formed by the first reflective sheet 1033 and the third reflective sheet 1035 .

[0089] For example, combined with Figure 6 , a marking line 1039 may be provided on the handle portion 1034b, combined with Figure 6 and Figure 1 The marking line 1039 can more precisely determine the moving distance of the first light adjustment pattern 1037 in the second reflector 1034 to ensure that the moving distance of the second reflector 1034 makes the first opening 1036 in the first reflector 1033 and the first light adjustment pattern 1037 in the first reflector 1033 in an interlaced state, that is, the marking line 1039 can be used to determine the interlaced length of the first light adjustment pattern 1037 in the second reflector 1034 and the first opening 1036 in the first reflector 1033, so that the overlapping area between the first opening 1036 in the first reflector 1033 and the first light adjustment pattern 1037 in the second reflector 1034 can be more precisely adjusted to change the overall reflectivity of the reflective structure 103 to light, so that the reflective structure 103 achieves the expected light emitting effect.

[0090] For example, Figure 1 As shown, the backlight assembly 101 further includes a back plate 107, which includes a side plate 1071 and a bottom plate 1072. The side plate 1071 is configured to support the middle frame 102, and the light source structure 104 is disposed on the bottom plate 1072. Figure 1 In the embodiment, the second portion 1032 of the reflective structure 103 abuts against the edge of the side plate 1071. The third reflective sheet 1035 included in the reflective structure 103 is in direct contact with the back plate 107 to achieve the supporting function of the back plate 107 on the reflective structure 103. For example, the third reflective sheet 1035 and the back plate 107 are in line contact.

[0091] For example, Figure 7 A three-dimensional structural diagram of a display device provided by at least one embodiment of the present disclosure, combined with Figure 1 and Figure 7 The side plate 1071 is provided with a groove 109, and the handle portion 1034b extends into the groove 109 to engage and fix the handle portion 1034b. Figure 7 Only the handle portion 1034b on the left side is shown, and the handle portion on the right side is not shown. In the actual product, there is also a handle portion on the right side, and the handle portion 1034b on the right side is also fixed in the groove 109 of the side panel 1071, thereby fixing the entire second reflector 1034.

[0092] For example, during the use of the display device, when problems such as dark frames or dark lines on the edges appear in the peripheral image quality of the display device, the handle portion 1034b of the second reflective sheet 1034 is pulled out of the groove 109 without disassembling the display device, and pulled outward for a distance along the extension of the second reflective sheet 1034. Then, the first light adjustment pattern 1037 in the second reflective sheet 1034 and the first opening 1036 in the first reflective sheet 1033 are staggered, so that the first light adjustment pattern 1037 printed on the second reflective sheet 1034 can be seen through the first opening 1036 in the first reflective sheet 1033. When the first light adjustment pattern 1037 is a black dot, the surface of the black dot will absorb part of the light, thereby reducing the overall reflectivity of the reflective structure, thereby improving the bright and dark line problems around the display device and improving the uniformity of the image quality of the display device.

[0093] For example, Figure 8 The actual photo of the display device provided in at least one embodiment of the present disclosure shows that the volume of the entire display module can be reduced by using the groove 109 located on the side plate 1071 to accommodate the handle portion 1034b, and the entire display device does not have any sharp or easily scratched parts. Moreover, the handle portion 1034b extends outside the outer shell portion and fits with the outer shell portion. Under the premise of ensuring safety during use and transportation, the overlapping area between the first opening 1036 in the first reflector 1033 and the first light adjustment pattern 1037 in the second reflector 1034 can be conveniently adjusted through the handle portion 1034b.

[0094] For example, Fig. 9 A schematic structural diagram of a first light adjustment pattern in a second reflective sheet and a first opening in a first reflective sheet in an embodiment of the present disclosure in a staggered state; Fig.10 A schematic diagram of a structure in which the first light adjustment pattern in the second reflector and the first opening in the first reflector are overlapped in an embodiment of the present disclosure, combined with Fig. 9 and Fig.10 , schematically, in Fig. 9 The first light adjustment pattern in the second reflector and the first opening in the first reflector are completely staggered, and the four light beams are completely reflected after entering the first opening 1036 in the first reflector 1033. Fig.10In the embodiment, the first light adjustment pattern 1037 in the second reflector 1034 and the first opening 1036 in the first reflector 1033 are in a partially overlapping state. After the four light beams are incident on the first opening 1036 in the first reflector 1033, only two light beams are completely reflected back, and part of the other two light beams are absorbed by the first light adjustment pattern 1037, and part of them are reflected by the reflective structure, which is equivalent to that the reflectivity of the other two light beams is reduced by a part. Therefore, without disassembling the display device, the first light adjustment pattern in the second reflector and the first opening in the first reflector can be staggered by pulling the handle part 1034b, thereby improving the problem of bright lines around the display device and further improving the uniformity of the overall picture quality of the display device.

[0095] For example, Fig.11 for Fig. 9 Schematic diagram of the corresponding light reflection, Fig.12 for Fig.10 Schematic diagram of the corresponding light reflection, comparison Fig.11 and Fig.12 , it can be clearly seen that Fig.11 The amount of light reflected from the Fig.12 The amount of light reflected in the image. Fig.13 for Fig. 9 The display image of the display device in the shown state, Fig.14 for Fig.10 The display image of the display device in the shown state, Fig.13 The display brightness of the corresponding display device is significantly greater than Fig.14 The display brightness of the corresponding display device, and Fig.13 The displayed image shown has a bright line on the right edge. Fig.14 There are no bright lines in the displayed image shown. Therefore, when bright lines appear in the image displayed by the display device, the overall reflectivity of the reflective structure 103 to light can be changed by adjusting the overlapping area between the first opening 1036 in the first reflective sheet 1033 and the first light adjustment pattern 1037 in the second reflective sheet 1034, thereby eliminating the problem of bright lines on the edges.

[0096] For example, when using a spliced ​​screen, there will be mutual squeezing between adjacent display modules that make up the spliced ​​screen. When the outer side of the middle frame is squeezed, it is easy to cause the middle frame to turn inward, and the supporting part of the middle frame's supporting reflective adhesive will shift inward. The width of the bonding between adjacent display modules is small (<1.2mm), and the inward shift of the supporting part of the middle frame's supporting reflective adhesive can easily block the edge pixels, making the size of the actual splicing seam smaller than the design value. For example, Fig.15 A schematic diagram of a cross-sectional structure in which edge pixels are blocked when the middle frame of a display module is turned inward. Fig.16The cross-sectional structure diagram of a display module in which the edge pixels are blocked and the reflective structure is squeezed when the middle frame is turned inward. Fig.15 As shown in , the dotted frame is where the middle frame is after it turns inward, and it will block the edge pixels at the upper end of the middle frame. Fig.16 As shown, when the middle frame is turned inward, not only the upper end of the middle frame blocks the edge pixels, but the reflective structure is also squeezed and deformed at the lower right corner, causing the reflective structure to bulge toward the side away from its corresponding side panel, thereby deteriorating the peripheral image quality of the display screen, and easily causing dark edge lines, bright edge lines or dark frames.

[0097] Therefore, it is possible to consider designing the support point of the side panel to the middle frame on the inner side of the middle frame to reduce the risk of the middle frame turning inward. Fig.17 A schematic diagram of a cross-sectional structure of a back plate as a whole and a middle frame provided in at least one embodiment of the present disclosure, such as Fig.17 As shown, the middle frame 102 and the back panel 107 form a whole, and the edges of the middle frame 102 away from the cavity 108 are all on the outside of the bent edges of the side panels 1071, and the support point A of the side panels 1071 to the middle frame 102 is located between the middle frame 102 and the cavity 108. Since the support point A is located on the inner side of the middle frame 102, the middle frame 102 is not prone to inversion, so that the overall structure of the display module is more stable.

[0098] For example, Fig.18 A schematic diagram of a cross-sectional structure of a backplane provided in at least one embodiment of the present disclosure, such as Fig.18 As shown, the side panels 1071 are symmetrically arranged on the left and right sides, and the side panels 1071 symmetrically arranged on the left and right sides are connected by a bottom plate 1072 located between the two opposite side panels 1071. The side panels 1071 are formed of electro-galvanized steel plates so that the side panels 1071 have a certain supporting strength. Fig.17 and Fig.18 The side panels 1071 on each side adopt a secondary bending design, and the bending directions of the opposite side panels 1071 are the same to form a cavity 108 between the opposite side panels 1071 , and the light source structure 104 is formed in the cavity 108 .

[0099] It should be noted that, combined with Fig.18 The secondary bending can be a first bending at the M position and a second bending at the N position.

[0100] For example, Fig.17As shown, the middle frame 102 includes a main body 102a, and the plane shape of the main body 102a is a parallelogram. Of course, the embodiments of the present disclosure are not limited thereto. The plane shape of the main body 102a can also be other shapes, and the middle area of ​​the main body 102a can also be hollowed out or made of a material with higher transparency. The extension direction of the side plate 1071 is the first direction X, and the extension direction of the bottom plate 1072 is the second direction Y. The parallelogram includes a first side 1021 and a second side 1022 extending in the second direction Y and arranged opposite to each other. The first side 1021 is the uppermost side of the parallelogram, and the second side 1022 is the lowermost side of the parallelogram. The middle frame 102 further includes a first branch portion 1023 extending in the first direction X and connected to the edge of the first side 1021 away from the cavity 108, and a second branch portion 1024 extending in a direction opposite to the first direction X and connected to the edge of the second side 1022, and the first branch portion 1023 and the second branch portion 1024 are both long strips. The support point of the side plate 1071 for the middle frame 102 is located on the side of the second branch portion 1024 close to the cavity 108, thereby preventing the risk of the middle frame 102 turning inward.

[0101] For example, Fig.17 As shown, the side plate 1071 includes a first side plate portion 1071a and a second side plate portion 1071b that are detachably connected, and the first side plate portion 1071a and the second side plate portion 1071b are connected by screws and a second branch portion 1024, and the first side plate portion 1071a is in contact with the middle frame 102 to support the middle frame 102. For example, in Fig.17 In the structure shown, the second branch portion 1024 is also divided into a portion located on the upper side of the screw and a portion located on the lower side of the screw. The portion located on the upper side of the screw and the portion located on the lower side of the screw of the second branch portion 1024 are detachable and separable from each other.

[0102] For example, Fig.17 As shown, the second side plate portion 1071b includes a bent portion 1072 bent toward one side of the cavity 108. Figure 1 and Fig.17 The third reflective sheet 1035 included in the reflective structure 103 rests on the bending portion 1072 to support the third reflective sheet 1035, so that the reflective structure 103 is less likely to be bent, thereby ensuring that the reflective structure 103 stably reflects the light incident thereon, thereby ensuring the reflection effect of the reflective structure 103 on light.

[0103] For example, in a spliced ​​screen formed by splicing multiple display modules, whether there is a splicing seam or the size of the splicing seam is one of the important physical parameters for evaluating the performance of the spliced ​​screen. In order to minimize the splicing seam of the spliced ​​screen or eliminate the splicing seam, the design of the spliced ​​screen should try to avoid the side edges affecting the splicing seam. Fig.18 As shown, a receiving space 1073 is formed at the bending position of the side panel 1071. The receiving space 1073 is a fixed area for a printed circuit board (PCB board), thereby ensuring that there is space for placing the printed circuit board and that there is no seam between two adjacent display modules of the spliced ​​screen.

[0104] For example, Fig.19 A schematic diagram of a three-dimensional structure of a middle frame provided in at least one embodiment of the present disclosure, Fig. 20 for Fig.19 The schematic diagram of the three-dimensional structure of the corners of the dotted frame in the middle frame is shown as follows: Fig.19 As shown, the four sides of the middle frame are all split-type designs, and the four corners of the middle frame 102 are connected by connecting pieces to form a frame shape. Fig. 20 The four corners of the middle frame 102 are fixedly connected by connecting pieces 1021 and screws 1022 .

[0105] For example, Figure 1 As shown, the display module 10 also includes a diffuser plate 110 and an optical film material 111 stacked on one side of the main surface of the parallelogram of the middle frame 102 away from the bottom plate 1072, a portion of the main surface of the diffuser plate 110 close to the bottom plate 1072 is connected to the first side 1021 of the middle frame 102, and the side surface of the optical film material 111 is connected to the first branch portion 1023 of the middle frame 102 via a reflective adhesive 112.

[0106] For example, Fig.21 A partially enlarged structural schematic diagram of a reflective adhesive provided in at least one embodiment of the present disclosure, such as Fig.21 As shown, the reflective adhesive 112 includes a fourth reflective sheet 1121, a fifth reflective sheet 1122 and a sixth reflective sheet 1123 which are stacked, and a main part of the fifth reflective sheet 1122 is disposed in a receiving space defined by the fourth reflective sheet 1121 and the sixth reflective sheet 1123, and can move relative to the fourth reflective sheet 1121. For example, Fig. 22 for Fig.21 The overall planar structural diagram of the fourth reflector, Fig.23 for Fig. 22 The middle part is an enlarged structural diagram of the fourth reflector. Fig.24 for Fig.21 A schematic diagram of the overall planar structure of a fifth reflector, Fig.25 for Fig.24 The middle part is a schematic diagram of the enlarged structure of the fifth reflector. Fig.26for Fig.21 Another schematic diagram of the overall planar structure of the fifth reflector, Fig. 27 for Fig.26 The middle part is a schematic diagram of the enlarged structure of the fifth reflector.

[0107] For example, combined with Fig. 22 and Fig.23 A third opening 1124 is provided in the middle portion of the fourth reflector 1121 , and the third opening 1124 allows light to pass through so that the light reaches the fifth reflector 1122 .

[0108] For example, Fig.24 and Fig.25 As shown, the surface of the fifth reflective sheet 1122 facing the fourth reflective sheet 1121 has at least one second light adjustment pattern 1125. Fig.24 What is shown is that the surface of the fifth reflector 1122 facing the fourth reflector 1121 has a plurality of second light adjustment patterns 1125, and the main part of the fifth reflector 1122 moves relative to the fourth reflector 1121 so that the overlapping area of ​​the third opening 1124 and the second light adjustment pattern 1125 changes.

[0109] Fig.28 A schematic diagram of a cross-sectional structure of the sky side and the ground side of a display device provided in at least one embodiment of the present disclosure, for example, Fig.28 As shown, reflective adhesive 112 is disposed on both the sky side and the ground side of the display module, and the surfaces of the fifth reflective sheet 1122 included in the reflective adhesive 112 on the ground side and the sky side and close to the fourth reflective sheet 1121 are both provided with second light adjustment patterns 1125 .

[0110] For example, the middle frame 102 supports a portion of the inner wall of the optical film material 111, and a reflective adhesive 112 is generally attached between the optical film material 111 and the first branch portion 1023 of the middle frame 102. The reflective adhesive 112 can reflect light, but the size of the gap between the diffuser 110 and the middle frame 102 directly affects the function of the reflective adhesive 112, thereby causing the image quality at the edge of the display device to deteriorate.

[0111] For example, during the stage of assembling the display device or transporting the display device, the diffuser plate 110 often shifts under the action of gravity, which may cause the gap d2 between the diffuser plate 110 and the middle frame 102 on the ground side to decrease, and the gap d1 between the diffuser plate 110 and the middle frame 102 on the sky side to increase. On the ground side, the reduction of the gap d2 between the diffuser plate 110 and the middle frame 102 may cause dark lines to appear at the edge of the display device, so it is necessary to increase the brightness of the ground side of the display device. On the sky side, the increase of the gap d1 between the diffuser plate 110 and the middle frame 102 may cause bright lines to appear at the edge of the display device, so it is necessary to reduce the brightness of the sky side of the display device.

[0112] For example, in Fig.24 and Fig.25 In the embodiment, the surface of the fifth reflective sheet 1122 facing the fourth reflective sheet 1121 has a plurality of second light adjustment patterns 1125. Fig.24 and Fig.25 In the structure shown, the reflective adhesive 112 is located on the ground side. The gap between the diffuser plate 110 and the middle frame 102 on the ground side of the display device is small, and dark lines are easily seen at the edge of the ground side of the display device. Therefore, it is necessary to improve the brightness of the display device. The second light adjustment pattern 1125 is a printed silver dot, which corresponds to the third opening 1124 one by one. The silver dot has a higher reflectivity to light, which can effectively improve the brightness of the ground side edge of the display device to improve the dark line problem at the ground side edge of the display device.

[0113] For example, in Fig.26 and Fig. 27 In the embodiment, the surface of the fifth reflective sheet 1122 facing the fourth reflective sheet 1121 has a plurality of second light adjustment patterns 1125. Fig.26 and Fig. 27 In the structure shown, the reflective adhesive 112 is located on the sky side. The gap between the diffuser plate 110 and the middle frame 102 on the sky side of the display device is large, and bright lines are likely to appear on the edge of the sky side of the display device. Therefore, it is necessary to reduce the brightness of the display device. The second light adjustment pattern 1125 is a printed black dot. The black dots correspond to the third openings 1124 one by one. The black dots have a low reflectivity to light, which can effectively reduce the brightness of the ground side edge of the display device to improve the problem of bright lines on the ground side edge of the display device.

[0114] For example, in one example, the diameter of the third opening 1124 is between 2 cm and 6 cm, and in the moving direction of the main part of the fifth reflector 1122 relative to the fourth reflector 1121, the distance between two adjacent third openings 1124 is greater than the diameter of the third opening 1124. In this way, the adjustment range of the overlapping area of ​​the third opening 1124 and the second light adjustment pattern 1125 can be larger to suit more application scenarios.

[0115] For example, Fig.25 and Fig. 27 As shown, in the direction in which the fifth reflective sheet 1122 moves relative to the fourth reflective sheet 1121 , reflective adhesive handles 1122 a are provided at both ends of the fifth reflective sheet 1122 , and the reflective adhesive handles 1122 a extend to the outside of the middle frame 102 .

[0116] For example, combined with Figure 8In the actual photo shown, the reflective adhesive handle 1122a is also contained in a groove, which can reduce the volume of the entire display module and prevent the entire display device from having sharp parts or parts that are easy to scratch the user. Moreover, the reflective adhesive handle 1122a extends outside the outer shell part and fits with the outer shell part. Under the premise of ensuring safety during use and transportation, the overlapping area between the third opening 1124 in the fourth reflector 1121 and the second light adjustment pattern 1125 in the fifth reflector 1122 can be conveniently adjusted through the reflective adhesive handle 1122a.

[0117] For example, Fig.28 As shown, the main part of the fifth reflector 1122 moves relative to the fourth reflector 1121, so that the overlapping area of ​​the third opening 1124 and the second light adjustment pattern 1125 changes. For example, the overlapping area of ​​the third opening 1124 and the second light adjustment pattern 1125 on the ground side becomes larger, so that the silver dots reflect the light, so that the reflectivity is improved, which can effectively improve the brightness of the ground side edge of the display device to improve the dark line problem of the ground side edge of the display device. For example, Fig.29 is a schematic diagram after the third opening on the ground side and the second light adjustment pattern overlap, for example, Fig.30 is the amount of light emitted before and after the third opening on the ground side overlaps with the second light adjustment pattern, Fig.30 The light path diagram on the left side of the middle shows the emission before the third opening on the ground side overlaps with the second light adjustment pattern. Fig.30 The light path diagram on the right side of the middle shows the emission amount after the third opening on the ground side and the second light adjustment pattern overlap. Fig.30 It can be seen that after the overlapping area of ​​the third opening 1124 and the second light adjustment pattern 1125 on the ground side increases, the emission amount of edge light increases significantly, and there is no problem of dark lines on the ground side edge.

[0118] For example, Fig.28 As shown, the overlapping area of ​​the third opening 1124 and the second light adjustment pattern 1125 on the sky side becomes larger, so that the black dots reflect the light and the reflectivity is reduced, which can effectively reduce the brightness of the sky side edge of the display device to improve the dark line problem on the sky side edge of the display device.

[0119] For example, Figure 1 As shown, the display module also includes a display component 113 disposed on a side of the optical film material 111 away from the bottom plate 1072, and an outer frame 114 disposed on a side of the middle frame 102 away from the side plate 1071, and the display component 113 is connected to the outer frame 114. The outer frame 114 can protect the internal structure of the display module. A display panel 113 is disposed on a side of the optical film material 111 away from the diffuser 110, and the display panel 113 is used to display images.
