[0024] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0025] A plug-in structure that facilitates the connection between FPC and connector, referring to Figure 1 , including a display module body 10, the display module body 10 includes a display screen 20 and a backlight module 30. The display screen 20 is accommodated in the backlight module 30, and the backlight module 30 is recessed inwardly on one side facing the display screen 20 to completely accommodate the entire display screen 20.

[0026] Reference Figure 2 The display screen 20 includes an upper polarizer 21, an upper glass 22, a lower glass 23, and a lower polarizer 24 arranged in sequence. The side of the lower polarizer 24 away from the lower glass 23 contacts the inner side of the backlight module 30. The size of the lower glass 23 is larger than that of the upper glass 22. A driver IC 40 is arranged on the side of the lower glass 23 facing the upper glass 22. The driver IC 40 is bound to the lower glass 23 beyond the upper glass 22. An FPC 50 is also arranged on the side of the lower glass 23 facing the upper glass 22. The FPC 50 is bound to the bottom of the driver IC 40. The FPC 50 is a flexible circuit board. One end of the FPC 50 is bound to the lower glass 23, and the other end of the FPC 50 is located outside the lower glass 23.

[0027] Reference Figure 2 A PCB mainboard 60 is disposed on the side of the backlight module 30 away from the display screen 20. The PCB mainboard 60 is attached to the back of the backlight module 30, and the size of the PCB mainboard 60 is smaller than the size of the backlight module 30. A connector 61 is disposed on the side of the PCB mainboard 60 away from the backlight module 30, and the connector 61 is used to connect with the FPC 50.

[0028] Reference Figure 1The end of the FPC 50 away from the lower glass 23 is provided with a plug-in end 51 for plugging with the connector 61. The plug-in end 51 is set in a round shape, and the plug-in end 51 is located near the edge of the side of the FPC 50 away from the lower glass 23. The lower side of the plug-in end 51 set in a round shape is open, and a plug-in portion 52 for plugging with the connector 61 is provided at the lower opening of the plug-in end 51. The plug-in portion 52 is used to connect with the connector 61, so that the FPC 50 is connected to the PCB main board 60.

[0029] Further, refer to Figure 3 and Figure 4 , the plug-in end 51 of the FPC50 is bent toward the back side of the backlight module 30 so that the plug-in end 51 is bent to the connector 61 of the PCB main board 60. When the FPC50 is bent, the position of the plug-in portion 52 of the FPC50 is set corresponding to the position of the connector 61, the plug-in portion 52 is correspondingly plugged with the connector 61, and the connector 61 enters from the side opening of the plug-in end 51 set in a round shape and plugs with the plug-in portion 52, so that the connector 61 is located in the plug-in end 51 set in a round shape, and the plug-in end 51 is sleeved outside the connector 61 to facilitate the connection between the plug-in end 51 of the FPC50 and the connector 61. There is no need to bend the plug-in end 51 of the FPC50 again. Even if the FPC50 has a downward rebound force, that is, the FPC50 has a rebound force toward the direction of the connector 61, it will also strengthen the connection between the connector 61 and the plug-in end 51 to enhance the connection firmness between the FPC50 and the connector 61.
