[0065] As described in the background art, in the related art, the source driver board is an important component in the display device, which can be used to receive, process and convert input signals, and send the processed signals to the display panel to display images. The source driver board is usually relatively fixed to the back plate, and the source driver board can also be electrically connected to the back plate, so that the source driver board can be grounded through the back plate, thereby improving the electromagnetic compatibility performance (EMC) and anti-static performance of the display device.

[0066] It is easy to understand that when the source driving board is fixed relatively to the back plate, it is necessary to first form adhesive and conductive foam on the source driving board, so that the surface of the adhesive facing away from the source driving board is bonded to the back plate, and the surface of the conductive foam facing away from the source driving board is electrically connected to the back plate. This makes the process of connecting the source driving board to the back plate complicated, the installation efficiency of the source driving board connected to the back plate is low, and after the display device has been used for a period of time, the adhesive between the source driving board and the back plate is prone to failure, etc., making the source driving board easy to fall off from the back plate.

[0067] In view of this, the display device of the embodiment of the present application is provided with a connecting bracket and a conductive spring sheet, so as to fix the source driving board by cooperating with the connecting bracket and the conductive spring sheet. The connecting bracket may include a main body and an abutting head, the main body may be fixedly connected to the back plate, the abutting head may move in a direction close to or away from the main body, so as to abut against the surface of the source driving board away from the back plate; the conductive spring sheet includes a connecting portion and a pressing portion connected to each other, the connecting portion is electrically connected to the back plate, the pressing portion faces the abutting head, so as to abut against the surface of the source driving board facing the back plate, so as to abut against both sides of the source driving board through the cooperating pressing portion and the abutting head.

[0068] When the source driving board is connected to the back plate, the source driving board can be inserted between the clamping part and the abutment joint, the abutment joint abuts against the surface of the source driving board facing away from the back plate, the clamping part abuts and pushes the source driving board to tightly abut the abutment joint, so that the source driving board can be fixed to the back plate through the clamping part and the abutment joint, and the clamping part is used to abut the conductive part of the source driving board, so that the source driving board can be electrically connected to the back plate through the conductive spring sheet.

[0069] Compared with the implementation in the related art that the source driving board is fixed to the back plate by adhesive bonding and electrically connected to the back plate through conductive foam, the display device of the embodiment of the present application can fix the source driving board by connecting the bracket and the conductive spring sheet, so that the source driving board is arranged between the clamping part and the abutment head, so that the source driving board and the back plate are relatively fixed, and the source driving board can also be electrically connected to the back plate, thereby improving the installation efficiency of the source driving board connected to the back plate, and the source driving board does not need to be fixed to the back plate by adhesive, so that the source driving board will not fall off from the back plate due to failure of the adhesive, and the connection between the source driving board and the back plate is more stable.

[0076] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0077] Reference Figure 1-Figure 3 An embodiment of the present application provides a display device, including a back panel 100 , a source driving board 400 , a connecting bracket 200 and a conductive spring 300 .

[0078] The source driving board 400 may be connected to the display panel 500. The source driving board 400 may have a conductive portion 410, and the source driving board 400 may be mounted on the back plate 100 through the connecting bracket 200 and the conductive spring sheet 300, and the conductive portion 410 of the source driving board 400 may be electrically connected to the back plate 100 through the conductive spring sheet 300.

[0079] The back plate 100 can at least be used to support structures such as a backlight module, etc. Moreover, the material of the back plate 100 can be set to be a conductive metal material, so that the source driving board 400 can be grounded through the back plate 100, thereby improving the electromagnetic compatibility and antistatic performance of the display device.

[0080] Reference Figure 4-Figure 6 Exemplarily, the connecting bracket 200 may include a main body 210 and an abutment head 220. The main body 210 may be fixedly connected to the back plate 100, and the abutment head 220 may move in a direction close to or away from the main body 210. The abutment head 220 and the main body 210 may be used to accommodate at least a portion of the source driving board 400, and the surface of the abutment head 220 facing the main body 210 may abut against the source driving board 400.

[0081] The conductive spring sheet 300 may include a connecting portion 310 and a pressing portion 320 connected to each other. The connecting portion 310 may be electrically connected to the back plate 100 .

[0082] The pressing portion 320 can be used in conjunction with the abutting head 220, and the pressing portion 320 can push the source driving board 400 to closely abut the abutting head 220, so that the source driving board 400 and the back plate 100 can be relatively fixed by using the pressing portion 320 and the abutting head 220. The pressing portion 320 is used to abut the conductive portion 410 of the source driving board 400, so that the source driving board 400 can be electrically connected to the back plate 100 through the pressing portion 320 and the connecting portion 310.

[0083] With such arrangement, when the source driving board 400 is connected to the back plate 100, the source driving board 400 can be inserted between the pressing portion 320 and the abutting joint 220, the abutting joint 220 abuts against the surface of the source driving board 400 away from the back plate 100, and the pressing portion 320 abuts and pushes the source driving board 400 to abut against the abutting joint 220, so that the source driving board 400 can be fixed to the back plate 100 through the pressing portion 320 and the abutting joint 220. The pressing portion 320 is used to abut against the conductive portion 410 of the source driving board 400, so that the source driving board 400 can be electrically connected to the back plate 100 through the conductive spring sheet 300.

[0084] In some possible implementations, the display device may have a sky side and a ground side that are arranged opposite to each other, and a left side and a right side that are arranged opposite to each other. When the display device is placed vertically, with the middle of the display device as a reference, the upper part of the display device forms the sky side of the display device, the lower part of the display device forms the ground side of the display device, the left part of the display device forms the left side of the display device, and the right part of the display device forms the right side of the display device.

[0085] Exemplarily, the source driving board 400 may be a square source driving board 400. In a first direction (i.e., the y direction in the figure), the source driving board 400 may be closer to the ground side of the display device than to the sky side of the display device, and the first direction may be parallel to the connection direction of the sky side of the display device and the ground side of the display device.

[0086] The extension direction of the source driving board 400 may be parallel to the second direction (i.e., the x direction in the figure), and the second direction may be parallel to the connection direction of the left side of the display device and the right side of the display device. The first surface of the source driving board 400 is provided with a conductive portion 410, the first surface of the source driving board 400 faces the back plate 100, and the second surface of the source driving board 400 faces away from the back plate 100.

[0087] In the first direction, the source driving board 400 may abut against the body 210 at a portion facing the ground side of the display device, and the source driving board 400 may be located between the pressing portion 320 and the abutting head 220 at a portion facing the sky side of the display device.

[0088] When the source driving board 400 is connected to the back plate 100 through the connecting bracket 200 and the conductive spring sheet 300, in a first direction, the source driving board 400 can be moved toward the sky side of the display device, so that the portion of the source driving board 400 facing the sky side of the display device is inserted between the clamping portion 320 and the abutment head 220, and the portion of the source driving board 400 facing the ground side of the display device abuts against the main body 210.

[0089] Exemplarily, the source driving board 400 may be arranged obliquely relative to the back plate 100. In the first direction, the distance between the end of the source driving board 400 facing the sky side of the display device and the back plate 100 is greater than the distance between the end of the source driving board 400 facing the ground side of the display device, so that the main body 210 can be used to support the source driving board 400 to a certain extent, making the installation of the source driving board 400 more convenient.

[0090] In some possible implementations, the number of the conductive springs 300 is set to be multiple. The multiple conductive springs 300 can be arranged along the second direction, so that the source driving board 400 can be electrically connected to the back plate 100 through the multiple conductive springs 300.

[0091] On the surface of the source driving board 400 away from the abutment head 220, the number of the conductive parts 410 can be set to be multiple. The multiple conductive parts 410 can be electrically connected to the pressing parts 320 of the multiple conductive springs 300. For example, the multiple conductive parts 410 can be arranged one by one with the multiple conductive springs 300, and each conductive part 410 can be electrically connected to the back plate 100 through a conductive spring 300. Alternatively, several conductive parts 410 can be electrically connected to the back plate 100 through the same conductive spring 300, and each conductive spring 300 is electrically connected to at least one conductive part 410.

[0092] For example, the number of the connecting brackets 200 may be one or more.

[0093] For example, the number of the connecting bracket 200 can be set to one, and the connecting bracket 200 can be connected to multiple conductive springs 300. In the connecting bracket 200, the number of the abutting joints 220 can be set to multiple, and the multiple abutting joints 220 can be arranged along the second direction, so that the surface of the source driving board 400 away from the back plate 100 can be abutted by the multiple abutting joints 220, so that the connection between the source driving board 400 and the back plate 100 is more stable.

[0094] The number of the connecting brackets 200 can be set to be multiple. The multiple connecting brackets 200 can be arranged along the second direction. The multiple connecting brackets 200 can be arranged in a one-to-one correspondence with the multiple conductive springs 300, and each connecting bracket 200 can be connected to a conductive spring 300, so that the abutting head 220 of each connecting bracket 200 can abut against the corresponding conductive spring 300 on both sides of the source driving board 400.

[0095] Alternatively, each connection bracket 200 may be connected to one or more conductive springs 300. The number of conductive springs 300 connected to the same connection bracket 200 may be the same, and the number of conductive springs 300 connected to the same connection bracket 200 may be different.

[0096] By adopting the above technical solution, when the source driving board 400 is connected to the back plate 100 through the connecting bracket 200 and the conductive spring sheet 300, in the second direction, the surface of the source driving board 400 facing away from the back plate 100 abuts against the abutting joints 220 of the multiple connecting brackets 200, and the surface of the source driving board 400 facing the back plate 100 abuts against the multiple conductive spring sheets 300, thereby fixing multiple positions of the source driving board 400 to the back plate 100, so that the connection between the source driving board 400 and the back plate 100 is more stable, further reducing the possibility of the source driving board 400 detaching from the back plate 100.

[0097] In some possible implementations, in the first direction, the main body 210 may be closer to the ground side of the display device than to the sky side of the display device.

[0098] The main body 210 can be fixed relatively to the back plate 100 by means of snap connection, plug connection, screw connection or welding, etc. The first surface of the main body 210 can face and fit the back plate 100, and the second surface of the main body 210 can face away from the back plate 100.

[0099] For example, refer to Figure 4 , Figure 5 and Figure 7 The first surface of the main body 210 may be provided with a card block 213 , and the back plate 100 may be provided with a card interface 110 .

[0100] The card block 213 can be inserted into the card interface 110 so that the main body 210 can be fixedly connected to the back plate 100 through the cooperation of the card block 213 and the card interface 110, thereby making the connection between the main body 210 and the back plate 100 more convenient.

[0101] The size of the clamping block 213 may be larger than the size of the card interface 110 , so that the clamping block 213 and the card interface 110 are interference-fitted, thereby making the clamping block 213 more stably installed in the card interface 110 .

[0102] Alternatively, the first portion of the clamping block 213 may be inserted into the card interface 110, and the second portion of the clamping block 213 may extend to the surface of the back plate 100 away from the main body 210. The size of the second portion of the clamping block 213 may be larger than the size of the card interface 110, and the clamping block 213 may be configured as an elastic clamping block 213, so that the second portion of the elastic clamping block 213 can be inserted through the card interface 110 to the side of the back plate 100 away from the main body 210.

[0103] In the main body 210 of the connecting bracket 200, the number of the clamping blocks 213 can be set to one or more. For example, the number of the clamping blocks 213 can be set to multiple, and the multiple clamping blocks 213 can be arranged along the second direction. In this way, by setting multiple clamping blocks 213, the connection between the connecting bracket 200 and the back plate 100 can be more stable, and the possibility of the main body 210 of the connecting bracket 200 falling off from the back plate 100 is reduced.

[0104] Reference Figure 6 and Figure 7 In some possible implementations, the main body 210 may be formed with a receiving groove 211 .

[0105] The receiving groove 211 may be located on the second surface of the main body 210, and the receiving groove 211 may be used to accommodate the source driving board 400, and the bottom surface of the receiving groove 211 may abut against the surface of the source driving board 400 away from the abutting head 220. In this way, the receiving groove 211 located on the main body 210 may play a certain limiting role on the source driving board 400, thereby reducing the possibility of the source driving board 400 moving relative to the connecting bracket 200.

[0106] For example, the main body 210 may be formed with a clearance groove 212 . The clearance groove 212 may be connected to the receiving groove 211 , and at least a portion of the clearance groove 212 may face the conductive portion 410 of the source driving board 400 .

[0107] The pressing portion 320 may be disposed in the clearance groove 212, and at least a portion of the pressing portion 320 extends out of the groove bottom surface of the receiving groove 211, and the portion of the pressing portion 320 extending out of the groove bottom surface of the receiving groove 211 may be electrically connected to the conductive portion 410. The pressing portion 320 can be connected to the conductive portion 410 of the source driving board 400 by being disposed in the clearance groove 212, so that the conductive portion 410 of the source driving board 400 can be electrically connected to the back plate 100 through the pressing portion 320.

[0108] With such an arrangement, when the source driving board 400 is connected to the back plate 100, the source driving board 400 can be moved along the first direction toward the sky side of the display device, so that the portion of the source driving board 400 facing the sky side of the display device is inserted between the clamping portion 320 and the abutment joint 220, the first surface of the source driving board 400 can be attached to the bottom surface of the accommodating groove 211, the conductive portion 410 located on the first surface of the source driving board 400 can face the yield groove 212, and the second surface of the source driving board 400 can abut against the abutment joint 220.

[0109] The clamping portion 320 located in the yield groove 212 can be tightly abutted against the conductive portion 410 of the source driving board 400, and push the surface of the source driving board 400 that is away from the back plate 100 to move toward the abutting head 220, so that the source driving board 400 can be fixed to the back plate 100 through the clamping portion 320 and the abutting head 220, and the source driving board 400 can also be electrically connected to the back plate 100 through the conductive spring sheet 300.

[0110] It should be noted that the number of the connecting bracket 200 is set to one, and the number of the conductive part 410 is set to multiple. The number of the abutment joints 220 can be set to multiple, and the multiple abutment joints 220 are all connected to the main body 210, and the multiple abutment joints 220 can be arranged along the second direction.

[0111] Exemplarily, the number of the receiving groove 211 can be set to one, and the receiving groove 211 can extend along the second direction. The number of the giving way grooves 212 can be set to multiple, and multiple giving way grooves 212 are connected to the receiving groove 211. Multiple giving way grooves 212 can be arranged in a one-to-one correspondence with multiple conductive springs 300, and each giving way groove 212 accommodates one conductive spring 300.

[0112] The number of the connecting brackets 200 can be multiple, and the number of the conductive parts 410 can be multiple. The multiple connecting brackets 200 can be arranged along the second direction, and the number of the conductive springs 300 can be multiple, and the multiple conductive springs 300 are arranged one-to-one with the multiple connecting brackets 200.

[0113] In some possible implementations, the abutment 220 may be connected to the body 210 .

[0114] Reference Figure 5-Figure 8 For example, the end of the abutment joint 220 facing the sky side of the display device can be fixedly connected to the main body 210. The end of the abutment joint 220 facing the ground side of the display device can be close to or away from the main body 210, so that the part of the source driving board 400 facing the sky side can be inserted between the main body 210 and the abutment joint 220, so that the source driving board 400 is fixed by the abutment joint 220 and the main body 210.

[0115] The abutment joint 220 can be set as an elastic abutment joint 220, which can drive the source driving board 400 to move toward the main body 210, so as to make the connection between the source driving board 400 and the connecting bracket 200 more stable and reduce the possibility of the source driving board 400 detaching from the connecting bracket 200.

[0116] Exemplarily, the conductive spring 300 may include a fixing portion 330. The fixing portion 330 may be connected to the main body 210, so that the connection between the conductive spring 300 and the main body 210 is more stable, and the possibility of the conductive spring 300 being separated from the connecting bracket 210 is reduced.

[0117] In some possible implementations, the abutment head 220 may be connected to the connection portion 310 .

[0118] Reference Figure 5 , Fig. 9 and Fig.10 Exemplarily, the conductive spring sheet 300 may include a fixing portion 330 . The fixing portion 330 may be connected to the abutting head 220 , and the fixing portion 330 is used to drive the abutting head 220 to closely abut against the source driving board 400 .

[0119] The first end of the fixing portion 330 can be connected to the connecting portion 310, and the second end of the fixing portion 330 is connected to the pressing portion 320. The fixing portion 330 is formed with a fixing groove 331, and the notch of the fixing groove 331 is away from the back plate 100, so that the abutment head 220 can be connected through the fixing groove 331.

[0120] The abutting head 220 has a bent portion 221 . The bent portion 221 extends toward the back plate 100 , and at least a portion of the bent portion 221 is disposed in the fixing groove 331 , so that the abutting head 220 can be connected to the fixing portion 330 through the bent portion 221 .

[0121] It is easy to understand that when the abutting head 220 is fixed relatively to the conductive spring sheet 300, the bent portion 221 of the abutting head 220 can be inserted into the fixing groove 331 of the fixing portion 330, so that the conductive spring sheet 300 can be connected to the abutting head 220 through the fixing portion 330, thereby realizing the installation of the abutting head 220;

[0122] When it is necessary to drive the abutment joint 220 away from the back plate 100, the abutment joint 220 can be pulled so that the abutment joint 220 drives the conductive spring sheet 300 to deform, thereby allowing the abutment joint 220 to move away from the back plate 100 and allowing the source driving plate 400 to be placed on the main body 210; then the abutment joint 220 is released, and the conductive spring sheet 300 can drive the abutment joint 220 to approach the main body 210, thereby allowing the abutment joint 220 to abut against the surface of the source driving plate 400 away from the back plate 100, thereby achieving the connection and fixation between the source driving plate 400 and the connecting bracket 200.

[0123] For example, refer to Figure 8-Figure 10 The conductive spring sheet 300 may further include a fitting portion 340. The fitting portion 340 may be connected to an end of the connecting portion 310 away from the pressing portion 320, a first surface of the fitting portion 340 may be fitted to the back plate 100, and a second surface of the fitting portion 340 may be fitted to the main body 210. The fitting portion 340, the connecting portion 310 and the fixing portion 330 may enclose a limiting groove 350, and the limiting groove 350 may accommodate at least a portion of the main body 210.

[0124] The bonding portion 340 is connected to one end of the connecting portion 310 away from the clamping portion 320, and the first surface of the bonding portion 340 is bonded to the back panel 100, and the second surface of the bonding portion 340 is bonded to the main body 210, so that the main body 210 and the back panel 100 can fix the bonding portion 340, so that the electrical connection between the back panel 100 and the bonding portion 340 is more stable, reducing the possibility of the conductive spring sheet 300 being detached from the back panel 100.

[0125] The fitting portion 340 , the connecting portion 310 and the fixing portion 330 form a limiting groove 350 , which accommodates at least a portion of the main body 210 , so that the conductive spring sheet 300 can be relatively fixed to the main body 210 of the connecting bracket 200 , thereby enabling the conductive spring sheet 300 to be relatively fixed to the back plate 100 through the connecting bracket 200 .

[0126] Reference Figure 5-Figure 8 In some possible implementations, a guide portion 222 may be provided at one end of the abutting head 220 facing the ground side of the display device, and an end of the guide portion 222 that is away from the abutting head 220 extends away from the back plate 100. When the source driving board 400 is connected to the back plate 100, the source driving board 400 can push the abutting head 220 to move away from the back plate 100 through the guide plate, making the process of the source driving board 400 passing between the main body 210 and the abutting head 220 more convenient.

[0127] And / or, the pressing portion 320 may be provided with a protrusion 321 . The protrusion 321 may face the abutting head 220 , and the protrusion 321 may abut against the conductive portion 410 of the source driving board 400 .

[0128] When the source driving board 400 is connected to the back plate 100, the source driving board 400 can drive the conductive spring sheet 300 to deform through the protrusion 321, and the clamping portion 320 moves toward the back plate 100, making the process of the source driving board 400 passing through the main body 210 and the abutment 220 more convenient, and the protrusion 321 abuts against the conductive portion 410 of the source driving board 400, making the electrical connection between the conductive spring sheet 300 and the source driving board 400 more stable.

[0129] In summary, the connection bracket 200 and the conductive spring sheet 300 are provided to fix the source driving board 400 by cooperating with the connection bracket 200 and the conductive spring sheet 300. The connection bracket 200 may include a main body 210 and an abutment head 220, the main body 210 may be fixedly connected to the back plate 100, and the abutment head 220 may move in a direction close to or away from the main body 210, so as to abut against the surface of the source driving board 400 away from the back plate 100; the conductive spring sheet 300 includes a connecting portion 310 and a pressing portion 320 connected thereto, the connecting portion 310 is electrically connected to the back plate 100, and the pressing portion 320 faces the abutment head 220, so as to abut against the surface of the source driving board 400 facing the back plate 100, so as to abut against both sides of the source driving board 400 through the matching pressing portion 320 and the abutment head 220.

[0130] When the source driving board 400 is connected to the back plate 100, the source driving board 400 can be inserted between the clamping portion 320 and the abutment joint 220, and the abutment joint 220 abuts against the surface of the source driving board 400 facing away from the back plate 100. The clamping portion 320 abuts and pushes the source driving board 400 to tightly abut the abutment joint 220, so that the source driving board 400 can be fixed to the back plate 100 through the clamping portion 320 and the abutment joint 220. The clamping portion 320 is used to abut the conductive portion 410 of the source driving board 400, so that the source driving board 400 can be electrically connected to the back plate 100 through the conductive spring sheet 300.

[0131] Compared with the implementation in the related art that the source driving board 400 is fixed to the back plate 100 by adhesive bonding and is electrically connected to the back plate 100 through conductive foam, the display device of the embodiment of the present application can fix the source driving board 400 by connecting the bracket 200 and the conductive spring 300, so that the source driving board 400 is arranged between the clamping part 320 and the abutment head 220, so that the source driving board 400 and the back plate 100 are relatively fixed, and the source driving board 400 can also be electrically connected to the back plate 100, thereby improving the installation efficiency of the source driving board 400 connected to the back plate 100, and the source driving board 400 does not need to be fixed to the back plate 100 by adhesive, so that the source driving board 400 will not fall off from the back plate 100 due to failure of the adhesive, and the connection between the source driving board 400 and the back plate 100 is more stable.

[0132] The present application provides a display device, including a back plate 100 , a source driving board 400 , a connecting bracket 200 and a conductive spring sheet 300 .

[0133] The connecting bracket 200 includes a main body 210 and an abutment joint 220. The main body 210 is fixedly connected to the back plate 100, and the abutment joint 220 can move in a direction close to or away from the main body 210; the conductive spring 300 includes a connecting portion 310 and a pressing portion 320 connected to each other, the connecting portion 310 is electrically connected to the back plate 100, and the pressing portion 320 faces the abutment joint 220.

[0134] When the source driving board 400 is inserted between the clamping portion 320 and the abutment joint 220, the abutment joint 220 abuts against the surface of the source driving board 400 facing away from the back plate 100, and the clamping portion 320 abuts and pushes the source driving board 400 to abut tightly against the abutment joint 220.
