Technical Field

[0001] This application relates to the field of display technologies, and particularly to a display device. Background Art

[0002] As the current mainstream display screen, the liquid crystal display screen has advantages such as low power consumption, small size, and low radiation. The liquid crystal display panel is usually used in combination with a backlight module. The backlight module is divided into a side-entry backlight module and a direct-lit backlight module. The direct-lit backlight module has higher brightness compared to the side-entry backlight module. Among them, the direct-lit backlight module usually uses a large number of Mini LED chips as the backlight source.

[0003] Since the design size of Mini LED display products is generally large, the size of the corresponding backlight module is large, which makes the size of the light guide plate used in the backlight module also large, resulting in an increase in the manufacturing difficulty and manufacturing cost of the light guide plate.

[0082] The liquid crystal display device mainly consists of a backlight module and a liquid crystal display panel. The liquid crystal display panel itself does not emit light and needs to rely on the light source provided by the backlight module to achieve brightness display. The imaging principle of the liquid crystal display device is to place the liquid crystal between two conductive glasses and, driven by the electric field between the two electrodes, cause the electro-optic effect of the liquid crystal molecules to twist, so as to control the transmission or shielding function of the backlight source, thereby displaying the image. If a color filter is added, a color image can be displayed.

[0083] Figure 1 It is a schematic cross-sectional structure diagram of the display device 100 provided by some embodiments of the present application; Figure 2 It shows a schematic structural diagram of the cooperation between the lamp board 121 and the display panel 110 in the display device 100 provided by some embodiments of the present application; for the convenience of description, only the content related to the embodiments of the present application is shown. Among them, Figure 2 It schematically shows the general situation of the adaptation setting of the lamp board 121 of the backlight module 120 and the display panel 110.

[0084] In some embodiments, please refer to Figure 1 , the display device 100 provided by the embodiments of the present application includes a display panel 110 and a backlight module 120. The display panel 110 is used to display images. The backlight module 120 is used to provide a backlight source for the display panel 110.

[0085] The display panel 110 can be a transmissive display panel 110, which can modulate the light transmittance but does not emit light itself. The display panel 110 has a plurality of pixel units arranged in an array, and each pixel unit can independently control the light transmittance and color of the light incident on the pixel unit from the backlight module 120, so that the light transmitted through all the pixel units forms a displayed image.

[0086] The size of the display panel 110 in the first direction F1 is greater than the size of the display panel 110 in the second direction F2. The first direction F1 and the second direction F2 intersect with each other and are both perpendicular to the thickness direction of the display panel 110. In the embodiments of the present application, with reference to Figure 2, the first direction F1, the second direction F2, and the third direction F3 are perpendicular to each other pairwise. The first direction F1 can be regarded as the length direction of the display panel 110, the second direction F2 can be regarded as the width direction of the display panel 110, and the third direction F3 is the thickness direction of the display panel 110. It can be understood that the first direction F1, the second direction F2, and the third direction F3 are only for illustrative purposes and are not limited thereto.

[0087] When the display device 100 is configured as a television, a mobile terminal, etc., generally, the display panel 110 can be set to be rectangular, and the display panel 110 has a top side, a bottom side, a left side, and a right side. Among them, the top side and the bottom side of the display panel 110 are oppositely arranged, and the left side and the right side of the display panel 110 are oppositely arranged. One end of the top side of the display panel 110 is connected to one side of the left side of the display panel 110, and the other end of the top side of the display panel 110 is connected to one side of the right side of the display panel 110. The bottom side of the display panel 110 is connected to the other end of the left side of the display panel 110 and the other end of the right side of the display panel 110 respectively. In the embodiments of the present application, with reference to Figure 1 and Figure 2 , the left side and the right side of the display panel 110 are oppositely arranged along the first direction F1, the top side and the bottom side of the display panel 110 are oppositely arranged along the second direction F2, and the thickness direction of the display panel 110 is the third direction F3.

[0088] Of course, in some other embodiments, it may also be that the left side and the right side of the display panel 110 are oppositely arranged along the second direction F2, and the top side and the bottom side of the display panel 110 are oppositely arranged along the first direction F1, which can be determined according to the specific usage situation and will not be specifically limited herein.

[0089] The backlight module 120 is usually located on the back of the display device 100. Specifically, the backlight module 120 is located on the light incident side of the display panel 110. That is, the display panel 110 is located on the light exit side of the backlight module 120. With reference to Figure 2 , the arrow on one side of the backlight module 120 indicates the light exit direction of the backlight module 120. The shape of the backlight module 120 is adapted to the shape of the display device 100, and the size of the backlight module 120 is adapted to the size of the display module. When the display device 100 is configured as a television, a mobile terminal, etc., the backlight module 120 usually can adopt a rectangular shape. The backlight module 120 in the embodiments of the present application can adopt a direct-lit backlight module 120, and the backlight module 120 is used to emit light more uniformly within the entire light exit surface of the display panel 110, so as to provide light with sufficient brightness and more uniform distribution for the display panel 110, so that the display panel 110 can display images normally.

[0090] The backlight module 120 generally includes a backplane (not shown in the figure) and a light board 121 located on the backplane. The backplane is located at the back of the backlight module 120 and has a supporting and bearing function. The backplane is usually a rectangular structure, and when applied to the special-shaped display device 100, its shape adapts to the shape of the display device 100. The top side, bottom side, left side, and right side of the backplane are adapted to the display panel 110, and can be understood by referring to the top side, bottom side, left side, and right side of the display panel 110, which will not be elaborated here. The material of the backplane can be aluminum, iron, aluminum alloy, iron alloy, etc. The backplane is used to support the light board 121 and the edge positions of related components such as a diffusion plate and optical films (not shown in the figure), and the backplane can also play a role in dissipating heat from the light board 121.

[0091] With reference to Figure 3 , Figure 3 FIG. shows a schematic structural diagram of the light board 121 in the display device 100 provided in some embodiments of the present application. The backlight module 120 includes at least one light board 121. The light board 121 includes a first part 121a, a plurality of first connectors 121b, a plurality of second parts 121c, and a plurality of light sources m.

[0092] Among them, both the first part 121a and the second part 121c can be made of a printed circuit board (PCB). Both the first part 121a and the second part 121c can be single-layer boards or multi-layer boards, which can be set according to actual usage requirements and are not specifically limited here.

[0093] The width of the first part 121a along the first direction F1 and the length along the second direction F2 can be set according to actual usage requirements. The first part 121a has two sides oppositely arranged along the first direction F1. In the embodiments of the present application, the two sides of the first part 121a oppositely arranged along the first direction F1 generally correspond to the left side and the right side of the display panel 110 respectively.

[0094] The first connector 121b is a component for realizing electrical connection between two components. Exemplarily, the first connector 121b can be configured as a connection terminal. Specifically, the plurality of first connectors 121b are connected to one side of the first part 121a along the first direction F1, and the plurality of first connectors 121b are arranged at intervals along the second direction F2. In this way, a plurality of structures that can be used to respectively connect the corresponding second parts 121c are formed on one side of the first part 121a along the first direction F1.

[0095] One end of the second part 121c is connected to a first connecting member 121b, and the other end extends along the first direction F1. That is to say, the second part 121c is generally a strip-shaped component. In the embodiment of the present application, when the first part 121a is disposed near the left side of the display panel 110, the second part 121c can be generally regarded as extending from the left side of the display panel 110 to the right side of the display panel 110; when the first part 121a is disposed near the right side of the display panel 110, the second part 121c can be generally regarded as extending from the right side of the display panel 110 to the left side of the display panel 110.

[0096] The light source m is a component that can be controlled to emit light. The plurality of light sources m are distributed on the first part 121a and the second part 121c. The light source m distributed on the first part 121a is electrically connected to the circuit in the first part 121a, and the light source m distributed on the second part 121c is electrically connected to the circuit in the second part 121c. The first part 121a and the second part 121c are electrically connected through the corresponding first connecting member 121b.

[0097] Exemplarily, the light source m can be an LED (Light Emitting Diode), a Mini LED (Mini Light Emitting Diode), or a Micro LED (Micro Light Emitting Diode). Since the sizes of the Mini LED and the Micro LED are very small, it is beneficial to control the dynamic light emission of the backlight module 120 into smaller partitions, thereby improving the dynamic contrast of the picture. The LED, the Mini LED, and the Micro LED can adopt a structure with a packaging bracket (such as a POB packaging structure), or can adopt a structure without a bracket (such as a CSP packaging structure), which is not limited herein. The light guide plate 121 can include light sources of one color, or can include light sources of multiple colors, which is not specifically limited herein.

[0098] It can be understood that if the first part 121a is disposed near the side of the display panel 110 along the second direction F2, it will cause the first part 121a to extend along the first direction F1, resulting in a longer longitudinal length of the first part 121a. However, in the embodiment of the present application, the first part 121a is disposed near the side of the display panel 110 along the first direction F1, such that the first part 121a is generally extending along the second direction F2, thereby enabling the longitudinal length of the first part 121a to be shorter. In this way, it is not only beneficial to reduce the size of the first part 121a, but also the width of the first part 121a along the first direction F1 can be controlled according to actual usage requirements.

[0099] Accordingly, the lamp board 121 of the backlight module 120 in the display device 100 is provided to include a first part 121a, a plurality of first connectors 121b, a plurality of second parts 121c, and a plurality of light sources m, such that each first connector 121b is connected between the first part 121a and a corresponding second part 121c. Since the display panel 110 has a relatively long dimension in the first direction F1, by arranging the first part 121a and the second parts 121c along the first direction F1, and configuring the second parts 121c to extend along the first direction F1, it is beneficial to reduce the size of the first part 121a. Meanwhile, by arranging a plurality of first connectors 121b on one side of the first part 121a along the first direction F1, it is convenient to connect the plurality of second parts 121c, which not only facilitates the manufacture of the lamp board 121, but also further helps to reduce the size of the first part 121a. Therefore, the display device 100 provided by the embodiments of the present application reduces the manufacturing difficulty of the lamp board 121 while reducing the manufacturing cost of the backlight module 120. Further, especially when the display device 100 is configured as a large-size television, it can greatly reduce the manufacturing cost of the first part 121a and the manufacturing difficulty of the lamp board 121.

[0100] Figure 4 FIG. shows a schematic structural diagram of a lamp board in a display device provided by some other embodiments of the present application; for ease of description, only the content related to the embodiments of the present application is shown.

[0101] According to some embodiments of the present application, please continue to refer to Figure 3 and, in combination with reference to Figure 4 , the first part 121a includes a first sub-part p1, a plurality of second sub-parts p2, and a driving chip (not shown in the figure).

[0102] The first sub-part p1 is the main part constituting the first part 121a. The first sub-part p1 has a first side c1 and a second side c2 oppositely arranged along the first direction F1.

[0103] The second sub-part p2 is a component extending along the first direction F1 compared with the first sub-part p1. The second sub-part p2 can be generally arranged in a strip shape. Specifically, the plurality of second sub-parts p2 are arranged at intervals along the second direction F2. The second sub-part p2 extends along the first direction F1 and has a first end e1 and a second end e2 oppositely arranged along the first direction F1. The plurality of first connectors 121b are arranged in one-to-one correspondence with the plurality of second sub-parts p2. Taking Figure 3 as an example, the first ends e1 of all the second sub-parts p2 are connected to the first side c1 of the first sub-part p1, and the first connectors 121b are connected to the second ends e2 of the corresponding second sub-parts p2; or, taking Figure 4For example, the first ends e1 of all the second sub-parts p2 are connected to the second side c2 of the first sub-part p1, and the first connecting member 121b is connected to the first side c1 of the first sub-part p1. In this way, the first part 121a is arranged substantially in a comb shape. Further, the plurality of light sources m are distributed on the first sub-part p1, the second sub-part p2, and the second part 121c.

[0104] Exemplarily, the dimension of the second sub-part p2 along the second direction F2 can be the same as the dimension of the aforementioned second part 121c along the second direction F2, the distance between two adjacent second sub-parts p2 along the second direction F2 is equal to the distance between two adjacent second parts 121c along the second direction F2, and the second sub-part p2 and the corresponding second part 121c can be arranged to extend along the same straight line.

[0105] The driving chip is used to convert the received signal into the electrical signal, timing, or power requirements required by the light source m, so as to realize the control of the light source m. The working process of the driving chip usually can include input signal processing, data switching and processing, or output signal generation, etc.

[0106] Thus, compared with the case where the first part 121a is integrally arranged in a plate shape, by setting the first part 121a into a structural form including the first sub-part p1 and a plurality of second sub-parts p2, the material used for the first part 121a can be reduced by means of the plurality of second sub-parts p2, thereby further reducing the manufacturing cost of the first part 121a. At the same time, arranging the driving chip on the first sub-part p1 and distributing the plurality of light sources m on the first sub-part p1, the second sub-part p2, and the second part 121c can not only improve the utilization rate of the first part 121a, but also facilitate the control of the light source m. When the first end e1 of the second sub-part p2 is connected to the first side c1 of the first sub-part p1, not only can the manufacturing cost of the first part 121a be further reduced, but also it is convenient to arrange the plurality of first connecting members 121b on the plurality of second sub-parts p2 one by one. When the first end e1 of the second sub-part p2 is connected to the second side c2 of the first sub-part p1, arranging the second sub-part p1 and the first connecting member 121b on both sides of the first sub-part p1 respectively can not only further reduce the manufacturing cost of the first part 121a, but also facilitate the flexible setting of the first connecting member 121b according to the use requirements, and further facilitate the manufacture of the second part 121c.

[0107] According to some embodiments of the present application, please continue to refer to Figure 3 , the plurality of second sub-parts p2 and the first sub-part p1 are of an integral structure.

[0108] Exemplarily, taking Figure 3 as an example, the first end e1 of the second sub-part p2 is connected to the first side c1 of the first sub-part p1, and the plurality of second sub-parts p2 and the first sub-part p1 are of an integral structure. Also exemplarily, takingFigure 4 For example, the first end e1 of the second sub - part p2 is connected to the second side c2 of the first sub - part p1, and the multiple second sub - parts p2 and the first sub - part p1 are of an integral structure.

[0109] Among them, the integral structure means that two components are connected into a whole instead of two independent components. Exemplarily, the way for the first sub - part p1 and the second sub - part p2 to form an integral structure can be welding, hot - melt welding or integral molding. Integral molding means a whole component formed by an integral molding process with the same material. It can be selected according to specific usage situations and is not specifically limited herein. In the embodiments of the present application, the first sub - part p1 and the second sub - part p2 are integrally molded parts.

[0110] In this way, by setting the second sub - part p2 and the first sub - part p1 of the first part 121a as an integral structure, the assembly process can be saved, thereby improving production efficiency and reducing manufacturing costs.

[0111] Figure 5 The structural schematic diagram of the lamp board 121 in the display device 100 provided by some other embodiments of the present application is shown; for the sake of convenience of description, only the content related to the embodiments of the present application is shown.

[0112] According to some embodiments of the present application, please refer to Figure 5 , the first end e1 of the second sub - part p2 is detachably connected to the first sub - part p1.

[0113] Exemplarily, the first part 121a may further include multiple second connectors p3. The multiple second sub - parts p2 and the multiple second connectors p3 are arranged in one - to - one correspondence, and the second connector p3 is connected between the first sub - part p1 and the corresponding second sub - part p2. Taking Figure 5 as an example, the first end e1 of the second sub - part p2 is detachably connected to the first side c1 of the first sub - part p1.

[0114] The second connector p3 is a component for realizing the electrical connection of two components, so that the second sub - part p2 is electrically connected to the first sub - part p1. For example, the second connector p3 can be configured as a connection terminal. Specifically, the multiple first connectors 121b are arranged at intervals along the second direction F2. In this way, a plurality of structures for respectively connecting the corresponding second sub - parts p2 are formed on one side of the first sub - part p1 along the first direction F1.

[0115] In this way, by setting the second sub - part p2 and the first sub - part p1 of the first part 121a as a split - type structure and connecting the first sub - part p1 and the second sub - part p2 through the second connector p3, the second sub - part p2 can be set more flexibly, and the length of the second sub - part p2 can be configured according to the actual usage situation to meet different usage requirements.

[0116] Of course, in some other embodiments, the first end e1 of the second sub-part p2 may be detachably connected to the second side c2 of the first sub-part p1. This can be flexibly configured according to actual usage and is not specifically limited here.

[0117] Figure 6 A schematic diagram of the structure of the lamp board 121 in the display device 100 provided in some further embodiments of the present application is shown; for ease of explanation, only the contents related to the embodiments of the present application are shown.

[0118] According to some embodiments of this application, please refer to Figure 6 The second portion 121c includes a plurality of sub-divisions n1 and at least one second connecting member n2. The plurality of sub-divisions n1 are arranged along the first direction F1, and the sub-divisions n1 extend along the first direction F1. The second connecting member n2 is connected between two adjacent sub-divisions n1 along the first direction F1.

[0119] The second connector n2 is a component used to realize electrical connection between two components, so that two adjacent subdivisions n1 along the first direction F1 are electrically connected. Exemplarily, the second connector n2 can be configured as a connection terminal.

[0120] In this way, by setting the second part 121c to include a plurality of sub-divisions n1, and connecting two adjacent sub-divisions n1 along the first direction F1 through the second connecting member n2, not only the difficulty of manufacturing the second part 121c can be reduced, but also the length of the second part 121c can be flexibly set according to the use requirements. It can be understood that in the case where the length of the second part 121c along the first direction F1 is long, by making a plurality of sub-divisions n1 connected, the difficulty of manufacturing the second part 121c can be greatly reduced.

[0121] Figure 7 A schematic diagram showing the structure of a light board 121 in a display device 100 provided in some other embodiments of the present application is shown; Figure 8 Shows Figure 7 A schematic structural diagram of the second part 121c in the provided structure; for ease of explanation, only the contents related to the embodiment of the present application are shown.

[0122] According to some embodiments of this application, please refer to Figure 7 and Figure 8 The second part 121c includes a first sub-division u1 and a plurality of second sub-divisions u2. The first sub-division u1 has a first connection side s1 and a second connection side s2 arranged opposite to each other along the first direction F1, and the first connection side s1 of the first sub-division u1 is connected to the corresponding first connection member 121b. The plurality of second sub-divisions u2 are connected to the second connection side s2 of the first sub-division u1, and one end of the second sub-division u2 that is away from the first sub-division u1 is extended along the first direction F1.

[0123] Exemplarily, taking Figure 7 and Figure 8 as an example, each sub-division u1 is connected to two second sub-divisions u2. Of course, it can also be that each sub-division u1 is connected to three, four or other numbers of second sub-divisions u2, which can be set according to specific usage situations and are not specifically limited herein.

[0124] In this way, by setting the second part 121c to a structural form including the first sub-division u1 and multiple second sub-divisions u2, the assembly process of the second part 121c can be saved, thereby improving production efficiency.

[0125] According to some embodiments of the present application, please continue to refer to Figure 7 and Figure 8 , the first sub-division u1 and the second sub-divisions u2 connected to the first sub-division u1 are of an integral structure.

[0126] Specifically, the first sub-division u1 and the second sub-divisions u2 connected to the first sub-division u1 are integrally formed parts. The first sub-division u1 can be arranged to extend along the second direction F2. In this way, the first sub-division u1 and the multiple second sub-divisions u2 can form a comb-like structure. Taking Figure 7 and Figure 8 as an example, the case where the second part 121c includes two second sub-divisions u2 is shown. At this time, the first sub-division u1 and the two second sub-divisions u2 generally form an n-shaped structure.

[0127] It should be noted that taking Figure 7 and Figure 8 as an example, in the case where the first part 121a includes the first sub-part p1 and the second sub-part p2, the second sub-part p2 and the second sub-divisions u2 can be arranged in one-to-one correspondence, that is, the number of the second sub-parts p2 is the same as the number of the second second parts u2, and the second sub-part p2 and the corresponding second second parts u2 both extend along the same straight line in the first direction F1. In this way, it is beneficial to control the light-emitting effect.

[0128] In this way, by setting the first sub-division u1 and the corresponding second sub-divisions u2 to an integral structure, the assembly process can be saved, thereby improving production efficiency and reducing manufacturing costs.

[0129] According to some embodiments of the present application, please continue to refer to Figures 3 to 8 , the light sources m on the second sub-part p1 are arranged along the first direction F1. That is, the arrangement direction of the light sources m on the second sub-part p1 and the extension direction of the second sub-part p1 are both the first direction F1.

[0130] Exemplarily, taking Figures 3 to 8For example, when the second sub - part p1 and the second part 121c are arranged in one - to - one correspondence, and the extension paths of the corresponding second sub - part p1 and the second part 121c are on the same straight line, the paths along which the light sources m on the second sub - part p1 are arranged in the first direction F1 and the paths along which the light sources m on the second part 121c are arranged in the first direction F1 are on the same straight line. Of course, in some other examples, the paths along which the light sources m on the second sub - part p1 and the light sources m on the second part 121c are arranged in the first direction F1 may not be on the same straight line. It can be set according to the specific usage situation, and no specific limitation is made here.

[0131] In this way, by arranging the light sources m on the second sub - part p1 in the first direction F1, it is convenient to manufacture the light sources m.

[0132] Figure 9 The structural schematic diagram of the lamp board 121 in the display device 100 provided by some other embodiments of the present application is shown; for the convenience of description, only the content related to the embodiments of the present application is shown.

[0133] According to some embodiments of the present application, please continue to refer to Figures 3 to 7 and, in combination with referring to Figure 9 The light sources m on the first sub - part p1 are arranged in columns along the first direction F1 and in rows along the second direction F2.

[0134] Exemplarily, taking Figures 3 to 7 as an example, the paths along which the light sources m in each row on the first sub - part p1 are arranged, the paths along which the light sources m on the second sub - part p1 are arranged in the first direction F1, and the paths along which the light sources m on the second part 121c are arranged in the first direction F1 are on the same straight line. Another example is, taking Figure 9 as an example, it shows the situation where, in addition to the situation shown by Figures 3 to 7 light sources m are also provided on the part of the first sub - part p1 that is not connected to the second sub - part p2. At this time, the light sources m on the first sub - part p1 are arranged in an array in the first direction F1 and the second direction F2. It can be set according to the specific usage situation, and no specific limitation is made here.

[0135] In this way, by arranging the light sources m on the first sub - part p1 in rows and columns, it is not only convenient to manufacture the light sources m, but also can improve the utilization rate of the first sub - part p1.

[0136] Of course, in some other embodiments, the light sources m on the first sub - part p1 can also be arranged according to other rules or arranged irregularly, which can be set according to the specific usage situation, and no specific limitation is made here.

[0137] According to some embodiments of the present application, please continue to refer to Figure 7 and Figure 8, the light sources m distributed on the first sub-division u1 and the second sub-division u2 are arranged in columns along the first direction F1 and in rows along the second direction F2.

[0138] In this way, by arranging the light sources m distributed on the first sub-division u1 and the second sub-division u2 in rows and columns, it is not only convenient to manufacture the light sources m, but also the utilization rate of the first sub-division u1 and the second sub-division u2 can be improved.

[0139] Of course, in some other embodiments, taking Figure 10 as an example, Figure 10 is a schematic structural diagram of the lamp board 121 in the display device 100 provided in some other embodiments of the present application, showing a case where the light sources m are provided on a part of the first sub-division u1 located between two adjacent second sub-divisions u2 along the second direction F2. The light sources m can be arranged on the first sub-division u1 according to actual usage conditions, and no specific limitation is made here.

[0140] Figure 11 shows a schematic structural diagram of the lamp board 121 in the display device 100 provided in some other embodiments of the present application; Figure 12 shows a schematic structural diagram of the lamp board 121 in the display device 100 provided in some other embodiments of the present application; for the convenience of description, only the content related to the embodiments of the present application is shown.

[0141] According to some embodiments of the present application, please refer to Figure 11 and Figure 12 , a plurality of first parts 121a are provided, and all the first parts 121a are arranged along the second direction F2. Two adjacent first parts 121a along the second direction F2 may be adjacent to each other or may be spaced apart from each other. In the embodiments of the present application, a case where two adjacent first parts 121a along the second direction F2 are spaced apart from each other is shown.

[0142] It should be noted that the plurality of first parts 121a can also be arranged in the structures shown in other drawings shown in the foregoing some embodiments, and can be flexibly set according to actual usage requirements, and no specific limitation is made here.

[0143] In this way, by providing a plurality of first parts 121a and arranging the first parts 121a along the second direction F2, the flexibility of arranging the first parts 121a is improved, and then the required first parts 121a can be configured according to actual usage requirements, which is beneficial to reducing the size of the rear shell of the display device 100 and reducing the manufacturing cost of the rear shell of the display device 100.

[0144] It can be understood that when there is a gap between two second parts 121c adjacent to each other along the second direction F2, two first parts 121a adjacent to each other along the second direction F2 may also have a gap, which can reduce the manufacturing cost of the first part 121a. Of course, in some other embodiments, two first parts 121a adjacent to each other along the second direction F2 may also be of an integral structure. In this way, the wire for wire outlet can be reduced, which further facilitates the assembly of the display device 100.

[0145] According to some embodiments of the present application, please refer to Figures 3 to 7 , Figures 9 to 12 , a wire outlet terminal w is provided on the first part 121a. Among them, Figure 4 and Figure 7 schematically show the wire outlet terminal w, but it is not labeled.

[0146] Exemplarily, two wire outlet terminals w may be provided on the first part 121a. When the first part 121a includes a first sub - part p1 and a second sub - part p2, the wire outlet terminal w may be provided on the first sub - part p1. Of course, in some other embodiments, the number of wire outlet terminals w on the first part 121a may also be set to other numbers. The wire outlet terminal w may be arranged close to the first side c1 of the first part 121a or close to the second side c2 of the first part 121a, and can be set according to the actual use situation, and no specific limitation is made here.

[0147] By providing the wire outlet terminal w on the first part 121a, it is beneficial to make the circuits of the lamp board 121 all lead out from the first part 121a, which is beneficial to reducing the occupation of the internal space of the display device 100, facilitating the design and assembly of the interior of the display device 100. At the same time, it is also beneficial to simplify the circuit design of the lamp board 121, the number of wires for wire outlet, and facilitate later maintenance and repair.

[0148] The technical features of the above - described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above - described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0149] The above - described embodiments only represent several implementation manners of the present application. Their descriptions are relatively specific and detailed, but they should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
