One end of the FPC is bound to the liquid crystal display screen, and the other end of the FPC is used to connect to the PCB board.

[0003] In the prior art, the PIN pitch of the FPC position where the display screen is bound is generally 0.2mm, while the PIN pitch of the plug-in position at one end of the FPC connected to the PCB is generally 0.5mm, so the width of the FPC at the position bound to the display screen is narrow, while the width of the FPC at the other end is relatively wide. Due to the limited number of PIN pins of the connector connected to the FPC on the PCB, the FPC uses two connecting plugs to plug with the connector on the PCB. However, the two connecting plugs that plug the FPC and the connector on the PCB are arranged horizontally side by side. The two connecting plugs arranged side by side make the width of the FPC wider and also have requirements for the connector position on the PCB. Utility Model Content

[0024] Reference Figure 1 The display screen 20 is bound with FPC40, which is a flexible circuit board. One end of the FPC40 is bound to the display screen 20, and the other end of the FPC40 is located outside the display screen 20. The side of the FPC40 away from the display screen 20 is bent toward the back of the backlight module 30.

[0025] Reference Figure 2 A PCB board 50 is provided on the side of the backlight module 30 away from the display screen 20, and the PCB board 50 is fixed to the back of the backlight module 30. A connector for connecting with the FPC 40 is provided on the PCB board 50, and one end of the FPC 40 away from the display screen 20 is bent to the back of the backlight module 30 and plugged with the connector to ensure the normal use of the display screen 20.

[0026] Reference Figure 1 Two connecting plugs for connecting to the PCB board 50 are arranged at one end of the FPC 40 away from the display screen 20. The two connecting plugs are arranged vertically side by side. The two connecting plugs arranged vertically side by side will not increase the width and area of ​​the FPC 40, so as to save costs.

[0027] Reference Figure 1The two vertically arranged connection plugs are the first connection plug 41 and the second connection plug 42 from top to bottom. The first connection plug 41 is located in the middle of the FPC 40, and the second connection plug 42 is located at the end of the FPC 40. The FPC 40 is provided with a placement groove 60 relative to the first connection plug 41. The first connection plug 41 is located in the placement groove 60, and the first connection plug 41 is located on the upper side of the FPC 40 relative to the placement groove 60. The first connection plug 41 is connected to the FPC 40, and the first connection plug 41 extends downward from the connection with the FPC 40.

[0028] Further, refer to Figure 2 , a first connector 51 for connecting with the first connection plug 41 is provided on the PCB board 50. When the FPC 40 is bent to the back of the PCB board 50, the first connector 51 is located above the first connection plug 41, and the first connection plug 41 and the first connector 51 are aligned and plugged. The position of the placement groove 60 other than the first connection plug 41 is a receiving cavity 70 for receiving the first connector 51. The receiving cavity 70 is located on one side of the first connection plug 41. The size of the receiving cavity 70 is adapted to the size of the first connector 51, so that after the FPC 40 is bent, the first connector 51 is just located in the receiving cavity 70 and plugged with the first connection plug 41.

[0029] Reference Figure 1 and Figure 2 , the second connection plug 42 is located below the first connection plug 41, and the second connection plug 42 is located at the end of the FPC 40 away from the display screen 20. A second connector 52 for connecting with the second connection plug 42 is provided on the PCB board 50, and the second connector 52 corresponds to the position of the second connection plug 42. When the FPC 40 is bent to the back of the PCB board 50, the second connection plug 42 is aligned and plugged with the second connector 52. By providing two vertically arranged connection plugs, when the end of the FPC 40 away from the display screen 20 is bent to the back of the PCB board 50, the first connection plug 41 and the second connection plug 42 are aligned and plugged with the first connector 51 and the second connector 52 respectively, thereby reducing the width and area of ​​the FPC 40 and saving costs.
