Detailed Description
The backlight module generally includes: backlight, backplate 5 and gluey frame 3 isotructure. The back plate 5 and the rubber frame 3 are used for assembling and matching to support the display panel 1. Specifically, as shown in fig. 1 and 2, in the prior art, the bottom surface of the rubber frame 3 (the surface of the rubber frame 3 close to the backboard 5) is fixed to the backboard 5 by using the rubber frame fixing adhesive 4 tape. However, most of the conventional display devices have a rectangular shape with a plurality of corners, and correspondingly, the back plate 5 has a rectangular shape. In the prior art, the rubber frame 3 is usually disposed in the sidewall of the back plate 5, and the four corner positions of the rubber frame 3 are bent, so that although the rubber frame 3 and the back plate 5 can be fixed by the rubber frame fixing adhesive 4, the actual limit effect on the rubber frame 3 is limited, and the rubber frame 3 is easy to shift inwards (i.e., sink inwards). The display panel 1 and the backlight module cannot be normally assembled under the condition of the invagination, so that frequent alarm of equipment is caused, and normal input of the module is influenced.
In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Example 1:
as shown in fig. 3 and 4, the present embodiment provides a backlight module, which includes a back plate 5 and a rubber frame 3. The edge area of the backlight module comprises a side line area and a corner area; the back plate 5 corresponding to at least part of the corner area is connected with the rubber frame 3 in a nesting way.
The overall shape of the back plate 5 and the backlight module in this embodiment is substantially the same. Specifically, the shape of the back plate 5 may include a conventional rectangular shape, a rectangular shape with a chamfer, or the like. The backlight module has an edge region, as shown in fig. 3, the edge region of the backlight module may include a side edge region and a corner region (e.g., a circular frame region in fig. 3). The edge regions and the corner regions are alternately connected to form the whole edge region of the backlight module. Taking the shape of the backlight module as a rectangle with round corners as an example, the side line area of the backlight module is a main straight line part in the edge area; the corner regions are rounded corner regions. It should be noted that the corner region is connected to the side region, and the corner region also includes a certain linear portion. The rubber frame 3 is located at the edge region of the backlight module, that is, at the edge of the back plate 5.
In particular, in the present embodiment, the back plate 5 corresponding to at least a portion of the corner region is nested and connected with the rubber frame 3. In the prior art, although the rubber frame has the function of fixing the rubber 4, the rubber frame 3 is still easy to bend inwards in the corner area, and the inwards sinking occurs. In the embodiment, the rubber frame 3 and the back plate 5 in the corner area form a clamping structure through a nesting design, and the rubber frame 3 is guaranteed to have forced positioning constraint at the corner position, so that the rubber frame is prevented from sinking, and the problem that the rubber frame 3 sinks is fundamentally solved.
Preferably, one side of the rubber frame 3, which is close to the back plate 5 and corresponds to at least part of the corner area, is provided with a slot; the side wall of the back plate 5 corresponding to the rubber frame 3 is connected with the rubber frame 3 in a nested way through a slot. As shown in fig. 4, the back plate 5 generally includes a plate-shaped main body and side walls disposed at the periphery. In the prior art, as shown in fig. 1 and 2, the adhesive tape is generally disposed on the inner side of the sidewall of the back plate 5 (left side of the sidewall in fig. 2), and is connected to the back plate 5 through the adhesive frame fixing adhesive 4 on the bottom surface (below the adhesive frame 3 in fig. 2). Because the fixing firmness of the fixing method is not high enough, in the embodiment, the side wall of the back plate 5 corresponding to the part of the rubber frame 3 can be embedded in the slot formed on the side of the rubber frame 3 corresponding to the corner area part.
It should be noted that, in the prior art, the rubber frame 3 is usually disposed inside the side wall of the back plate 5. In this embodiment, in order to realize the nesting of the rubber frame 3 and the side wall of the back plate 5, the rubber frame 3 corresponding to the corner region should be located just above the side wall of the back plate 5. In order to realize such a structure, it is preferable that, as shown in fig. 3, the sidewall of the back plate 5 corresponding to the corner region and the sidewall of the back plate 5 corresponding to the adjacent edge region of the corner region form an invagination pattern. That is, in this embodiment, on the basis of the existing back plate 5, the sidewall of the back plate 5 can be divided into a plurality of portions, and the sidewall of the back plate 5 corresponding to the corner region is retracted inward (as shown in the circular frame region in fig. 3), so that the sidewall of the back plate 5 located in the corner region can be nested with the rubber frame 3. Based on this kind of design structure, can not take place great change to the whole profile of gluing frame 3, basically not have the influence to backlight unit's whole shape, infinitely improve display panel 1.
Of course, it can be understood that the nesting between the corner region and the sidewall of the back plate 5 can also be achieved by improving the outline of the rubber frame 3, but this structure may affect the support of the display panel 1, and the description of this embodiment is omitted here.
Preferably, in this embodiment, the glue frame 3 corresponding to the edge area is located on the inner side of the sidewall of the back plate 5. It is understood that the material of the rubber frame 3 may include rubber, plastic, etc., and the hardness thereof is much smaller than that of the back plate 5. Therefore, the overall shape of the backlight module is determined by the shape of the back plate 5, and the rubber frame 3 is mainly used for supporting the display panel 1. In this embodiment, in order to ensure the overall shape and strength of the appearance of the backlight module, the rubber frame 3 corresponding to the edge area is preferably located on the inner side of the sidewall of the back plate 5.
It is further preferred that the side walls of the back plate 5 corresponding to the edge zones are higher than the side walls of the back plate 5 corresponding to the corner zones. As shown in fig. 4, the height of the sidewall of the back plate 5 and the height of the rubber frame 3 are critical to the overall thickness of the backlight module. In this embodiment, since the sidewall of the back plate 5 corresponding to the corner area is nested with the rubber frame 3, and the rubber frame 3 corresponding to the side area is located inside the sidewall of the back plate 5, the structural design preferably ensures that the overall height of the backlight module is consistent and the strength of the backlight module is ensured as much as possible.
Preferably, the backlight module further comprises: and the light guide plate 9 is positioned on one side of the back plate 5 close to the rubber frame 3 and is positioned within the range limited by the rubber frame 3. It is understood that the backlight module may further include a light source, such as an LED light bar. Specifically, the light source may include a light bar, which may be disposed on a side surface of the light guide plate 9.

Meanwhile, a reflective sheet 10 may be disposed on a side of the light guide plate 9 facing away from the display surface. Light emitted from the light source is transmitted through the light guide plate 9, and light directly emitted to the display side (the side where the display panel 1 is disposed) and light reflected by the reflection sheet 10 are emitted together, and after being diffused and homogenized by the diffusion sheet, the upper and lower prisms 7, etc., the light can be uniformly emitted to the display panel 1, and a desired image can be displayed after passing through the display panel 1.
Preferably, in this embodiment, the rubber frame 3 further includes a limiting member disposed on a side of the rubber frame 3 away from the display panel 1. As shown in fig. 4, the plastic frame 3 is used for not only supporting the display panel 1, but also limiting the display panel 1, and in this embodiment, the display panel 1 can be limited by the limiting member on the plastic frame 3.
In the backlight module provided by this embodiment, the sidewall of the back plate 5 in the corner region is embedded in the rubber frame 3 to enhance the fixation between the rubber frame 3 and the back plate 5. Specifically, four corners of the back plate 5 are designed into special shapes, a nesting design is formed between the local parts and the rubber frame 3, and the nesting design ensures that the rubber frame 3 has forced positioning constraint at the corners, so that the rubber frame 3 cannot be sunken, and the problem of sunken rubber frame 3 is solved fundamentally.
