[0002] Liquid crystal display devices are widely used in various information, communication and consumer electronic products. Liquid crystal display modules are mainly composed of liquid crystal display screens and backlight modules. The connection between the backlight module and the liquid crystal display screen is usually to connect the backlight FPC on the backlight module with the main screen FPC on the liquid crystal display screen, and the main screen FPC is then connected to the customer's mainboard.

[0003] Currently, during the assembly of display modules, there are two ways to connect the backlight FPC and the main screen FPC. One is to fix one end of the backlight FPC on the main screen FPC through solder paste welding, and the other is to set a connector on the main screen FPC and plug the backlight FPC through the connector. However, solder paste welding may cause poor contact due to short circuit caused by immature operation, and plugging in the connector may cause poor contact because the plug-in end cannot be stuck in place. Both connection methods will lead to poor contact and cause adverse effects. Utility Model Content

[0023] 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.

[0024] Embodiment 1:

[0025] An embedded backlight structure, 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, and the display screen 20 and the backlight module 30 are attached to each other. The display screen 20 is bound with a main screen FPC 21, which is a flexible circuit board. The end of the main screen FPC 21 away from the display screen 20 is bent to the back of the backlight module 30, and the end of the main screen FPC 21 bent to the back of the backlight module 30 is attached to the back of the backlight module 30. The end of the main screen FPC 21 away from the display screen 20 is used to connect to the customer's mainboard to ensure the normal use of the display screen 20.

[0026] Reference Figure 1 The backlight module 30 is provided with a socket connection structure, which is used to replace the backlight FPC to connect with the customer's mainboard. The socket connection structure includes a connection line 40 and a socket 50. There are two connection lines 40, which are respectively a positive line 41 and a negative line 42. The two connection lines 40 are electrically connected to the inside of the backlight module 30. Both of the two connection lines 40 extend from the inside of the backlight module 30 to the outside of the backlight module 30. The ends of the two connection lines 40 away from the backlight module 30 are inserted into the socket 50 and are respectively connected to the corresponding positive and negative electrodes in the socket 50.

[0027] Further, refer to Figure 1 The two connecting wires 40 have the same length, and the length of the two connecting wires 40 is determined according to actual needs. The two connecting wires 40 are extended out of the backlight module 30 so that the socket 50 is located outside the backlight module 30, and the end of the socket 50 away from the two connecting wires 40 is connected to the customer's mainboard. By adopting the socket connection structure instead of the backlight FPC, the socket 50 is directly connected to the customer's mainboard to improve the poor display caused by improper operation, thereby improving product quality.

[0028] Further, refer to Figure 1 The two connecting wires 40 are provided with heat shrink tubes 60 for limiting the positions of the two connecting wires 40. The heat shrink tubes 60 are provided in a cylindrical shape. The heat shrink tubes 60 are provided outside the two connecting wires 40 to limit the positions of the two connecting wires 40 and prevent the two connecting wires 40 from being separated. The heat shrink tubes 60 are located outside the backlight module 30. In this embodiment, a plurality of heat shrink tubes 60 can be provided according to the actual length of the connecting wires 40 to better limit the positions of the two connecting wires 40.

[0029] Embodiment 2:

[0030] Reference Figure 2 The difference between this embodiment and the first embodiment is that a double-sided adhesive 70 for fixing two connecting wires 40 is provided on the back of the backlight module 30, and the double-sided adhesive 70 is located at the connection between the two connecting wires 40 and the backlight module 30. The double-sided adhesive 70 is arranged along the length direction of the two connecting wires 40, and the width of the double-sided adhesive 70 is adapted to the width of the two connecting wires 40. As the positions of the two connecting wires 40 are different, the position of the double-sided adhesive 70 changes accordingly. The two connecting wires 40 are fixed to the back of the backlight module 30 by the double-sided adhesive 70, so as to play the effect of limiting the two connecting wires 40, so that the section of the two connecting wires 40 connected to the backlight module 30 is fixed to the back of the backlight module 30, which is convenient for the socket 50 to be connected to the customer's mainboard.

[0031] Embodiment 3:

[0032] Reference Figure 3 The difference between this embodiment and embodiment 1 is that a groove 80 for accommodating two connecting wires 40 is opened on the back of the backlight module 30, the groove 80 is set along the length direction of the two connecting wires 40, and the groove 80 is opened along the placement position of the two connecting wires 40. The two connecting wires 40 are both accommodated in the groove 80, and the groove 80 limits the two connecting wires 40.

[0033] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
