Description

Technical Field

[0001] This utility model relates to the field of display module technology, and in particular to a display module that prevents warping. Background Technology

[0002] In an LCD display module, the backlight FPC of the backlight module is soldered to the module FPC of the display module and then connected to the motherboard of the entire unit through the module FPC. During subsequent assembly, the module FPC needs to be bent and attached to the back of the display module. At this time, the backlight FPC is also bent, so there will be rebound stress in the backlight FPC, which can cause the backlight FPC to warp. Even if there is double-sided tape on the bottom of the backlight FPC, warping can still occur at the solder joint due to stress, under conditions such as long-term exposure, vibration, high temperature and high humidity. This can lead to breakage of the circuits and pads at the FPC solder joint, resulting in damage to the display module.

[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a display module that prevents warping.

[0005] The technical solution of this utility model is as follows: This utility model provides a display module to prevent warping, including: a module FPC, a backlight module, and a high-temperature adhesive. The backlight module includes a backlight frame and a backlight FPC. The backlight FPC includes: a backlight connector for electrical connection with the module FPC, and a backlight connecting part for connecting the backlight connector. The backlight connector of the backlight FPC is welded to the backlight area of ​​the module FPC. A high-temperature sticker is attached to the backlight connector. The backlight FPC connector is welded to the backlight welding area of ​​the module FPC. The high-temperature adhesive is integrally attached to the backlight connector, the backlight welding area, and the backlight frame. The high-temperature adhesive avoids the backlight frame of the display module from the grounding ESD treatment area, the antenna RF clearance area, and the backlight connecting part.

[0006] Furthermore, the area of ​​the backlight frame to which the high-temperature adhesive is attached undergoes surface roughening treatment.

[0007] Furthermore, on both the left and right sides of the backlight connection portion, there are areas where the backlight frame is adhered by the high-temperature adhesive.

[0008] Furthermore, the backlight frame is a plastic frame, an iron frame, or a combined plastic and iron frame.

[0009] Furthermore, the thickness of the high-temperature adhesive is 0.05 mm.

[0010] The beneficial effects of this utility model by adopting the above solution are as follows: the high-temperature adhesive that is simultaneously bonded to the backlight welding area, the backlight connector, and the backlight frame can effectively fix the backlight connector of the backlight module, avoiding the problem of damage to the backlight circuit, backlight pads, etc. caused by the backlight FPC lifting due to stress, thus improving the quality of the product. Attached Figure Description

[0011] Figure 1 This is a structural schematic diagram of an embodiment of the present utility model.

[0012] Figure 2 This is an enlarged view of point A in this utility model.

[0013] Figure 3 This is an embodiment of the present utility model. Detailed Implementation The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] Please refer to the following: Figures 1 to 3 In this embodiment, the present invention provides a display module to prevent warping, comprising: a module FPC 1, a backlight module, and a high-temperature adhesive 4. The backlight module includes a backlight frame 3 and a backlight FPC 2. The backlight frame 3 is used to fix and house optical films, such as an adhesive frame, an iron frame, or an integrated adhesive-iron frame. The backlight FPC 2 includes: a backlight connector 21 for electrical connection with the module FPC 1, and a backlight connecting part 22 for connecting the backlight connector 21. The backlight connector 21 of the backlight FPC 2 is welded to the backlight area of ​​the module FPC 1. A high-temperature sticker is attached to the backlight connector 21. The connector of the backlight FPC 2 is welded to the module FPC. The backlight welding area 11 of module 1 is covered with a high-temperature adhesive 4, which is attached to the backlight connector 21, the backlight welding area 11 and the backlight frame 3. The high-temperature adhesive 4 strengthens the connection between the backlight connector 21 and the backlight welding area 11, and avoids the problem of lifting due to stress. The high-temperature adhesive 4 is an insulating material with a thickness of 0.05mm. Its left and right width does not exceed the outer edge of the module FPC1. The high-temperature adhesive 4 avoids the backlight connector 22, so as not to be lifted by the backlight connector and affect the bonding effect with the backlight frame 3. The high-temperature adhesive 4 avoids the grounding ESD treatment area and the antenna radio frequency clearance area of ​​the backlight frame 3 of the display module, so as not to adversely affect the normal function of the entire machine.

[0015] Furthermore, the area of ​​the backlight frame 3 to which the high-temperature adhesive 4 is attached undergoes surface roughening treatment, such as sanding, to ensure that the high-temperature adhesive 4 adheres more firmly to the backlight frame 3.

[0016] Furthermore, on both the left and right sides of the backlight connection part 22, there are areas where the backlight frame 3 is glued with high-temperature adhesive 4, which can ensure a better bonding and fixing effect.

[0017] In summary, the beneficial effects of this solution are as follows: by setting up high-temperature adhesive that is simultaneously bonded to the backlight welding area, the backlight connector, and the backlight frame, the high-temperature adhesive can effectively fix the backlight connector of the backlight module, avoiding damage to the backlight circuitry and backlight pads caused by stress-induced warping of the backlight FPC, thus improving product quality.

[0018] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
