Description

Technical Field

[0001] The utility model relates to the technical field of backlight structures, and more specifically to a backlight structure with an arc-shaped supporting retaining wall. Background Art

[0002] In the manufacturing and design of liquid crystal displays (LCDs), flexible printed circuits (FPCs) are the key bridges that connect TFT liquid crystal glass substrates with drive circuits or other electronic components. The stability and reliability of their performance directly affect the display effect and service life of the entire display. FPCs have been widely used in the LCD industry for their good flexibility, thin size, and efficient signal transmission capabilities. However, as LCD products develop towards higher resolution, thinner, and more durable directions, FPCs also face many challenges in design and application. In particular, during the assembly process of LCD modules, FPCs usually need to undergo complex bending processes to adapt to product structure requirements.

[0003] In traditional LCD module design, the FPC is often directly attached to the back of the backlight module after being bent, and fixed by adhesive or other fixing methods. However, this design method has obvious limitations. Stress concentration occurs at the bend of the FPC, and it is very easy to be damaged by creases, fractures, etc. when used for a long time or subjected to external impact. Therefore, we have improved this and proposed a backlight structure with an arc-shaped support wall.

[0004] For example, a Chinese patent (publication number CN220357389U) discloses a backlight FPC, a backlight module and a display module, and its specification discloses: In the backlight FPC, since the backlight FPC needs to be welded or plugged into the corresponding pad or interface of the module FPC after the backlight module and the liquid crystal display module are assembled, the subsequent module FPC needs to be bent and set on the back of the backlight module, so the backlight FPC also needs to be bent. The PI (polyimide) reinforcement edge of the conventional backlight FPC is a straight line and is located on the same line as the bending area, which can easily cause the backlight FPC to crack when bent, affecting the circuit damage and causing the backlight to not be bright. The above patents can prove the defects of the existing technology. Utility Model Content

[0005] The technical problem to be solved by the embodiments of the present invention is that after the FPC is bent, stress concentration is generated at the bending point, and when used for a long time or subjected to external impact, it is very easy to cause damage such as creases and breaks.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A backlight structure with an arc-shaped supporting retaining wall comprises: a backlight body and an FPC body arranged on the backlight body, wherein the FPC body is bent, and an arc-shaped supporting retaining wall body is arranged on one side of the backlight body close to the bending area of ​​the FPC body, and the outer surface of the arc-shaped supporting retaining wall body is in contact with the bending area of ​​the FPC body to achieve support of the bending area of ​​the FPC body by the arc-shaped supporting retaining wall body.

[0008] As an improved manner of the present invention, a display module is disposed on one side of the backlight body, and the display module is connected to the FPC body.

[0009] As an improved manner of the utility model, the arc-shaped supporting retaining wall body is arranged between the display module and the backlight body, and a side of the arc-shaped supporting retaining wall body away from the backlight body and the display module is arranged in an arc shape.

[0010] As an improved manner of the utility model, an adhesive layer is provided on the outer surface of the arc-shaped supporting retaining wall body, and the arc-shaped supporting retaining wall body is bonded to the bending area of ​​the FPC body through the adhesive layer.

[0011] As an improvement of the utility model, the arc-shaped supporting retaining wall body is block-shaped, and the middle part of the arc-shaped supporting retaining wall body is solid.

[0012] As an improved manner of the utility model, a side of the arc-shaped supporting retaining wall body close to the backlight body and the display module is fixedly connected to the backlight body and the display module.

[0013] As an improved manner of the utility model, a connecting piece is provided between the arc-shaped supporting retaining wall body and the backlight body, and the connecting piece is used for connecting the arc-shaped supporting retaining wall body and the backlight body.

[0014] As an improved manner of the utility model, the connecting member includes a connecting block fixedly mounted on the arc-shaped supporting retaining wall body and a connecting groove opened on the backlight body, and the connecting block is plugged into the inner wall of the connecting groove.

[0015] As an improved manner of the present invention, the connecting piece is double-sided adhesive, and the double-sided adhesive is bonded between the arc-shaped supporting retaining wall body and the backlight body and the display module.

[0016] As an improved manner of the utility model, the arc-shaped supporting retaining wall body is arranged in an arc-shaped sheet shape, and two ends of the arc-shaped supporting retaining wall body are respectively fixedly connected to the FPC body and the backlight body.

[0017] Compared with the prior art, the embodiments of the present invention mainly have the following beneficial effects:

[0018] In order to solve the problem in the prior art that after the FPC is bent, stress concentration is generated at the bending part, and creases, fractures and other damages are very likely to occur when used for a long time or subjected to external impact, the application discloses that an arc-shaped supporting retaining wall body is arranged at the backlight body close to the bent part of the FPC body. The arc-shaped supporting retaining wall body can provide a stable supporting surface for the bent part of the FPC body, effectively disperse the stress at the bending part of the FPC body, and reduce the creases or fractures caused by stress concentration at the bending part of the FPC body. The bent part of the FPC body is not only attached to the back of the backlight body, but also closely fits on the outer surface of the arc-shaped supporting retaining wall body. This double support structure significantly enhances the fixing effect of the FPC body and reduces the risk of shaking and damage due to external force. BRIEF DESCRIPTION OF THE DRAWINGS
