When the liquid crystal display device adopts the direct type backlight module to provide backlight, the frame 40 of the liquid crystal display device covers the peripheral edge of the liquid crystal panel and is fixedly connected with the back plate of the direct type backlight module, so as to shield the peripheral black edge of the liquid crystal panel and protect the internal circuits.
However, with the development of narrow frames of liquid crystal display devices, the liquid crystal display device using the direct-type backlight module has a narrow frame design that is difficult to implement. Specifically, referring to fig. 2, in the direct-type backlight module, in order to prevent the diffusion plate 20 from abutting against the support ribs 31 after expansion, a certain expansion gap a needs to be reserved between the diffusion plate 20 and the support ribs 31; in order to ensure the stability of the rubber frame 30 supporting the liquid crystal panel and prevent the rubber frame 30 from turning over toward the center of the bottom plate 10, a certain gap c is also left between the support rib 31 and the vertical wall of the rubber frame 30 (contacting with the outermost folded edge of the U-shaped bend 13), and in addition, in order to ensure that the support rib 31 has enough support strength, the support rib 31 has a certain width b, and the width d of the frame 40 needs to be greater than the sum of the expansion gap a, the width b, the gap c and the thickness of the vertical wall of the rubber frame, so as to play a role in shielding the black edge of the liquid crystal panel and fixing the liquid crystal panel. It should be noted that the thickness of the folded edge of the back plate is much smaller than the gap c, and therefore, can be ignored.

In order to further explain the direct type backlight module and the liquid crystal display device provided by the embodiment of the invention, the following description is made in detail with reference to the accompanying drawings.
Referring to fig. 4 and 5, a direct type backlight module according to an embodiment of the present invention includes: a back plate, a diffusion plate 20 mounted on the back plate, and a rubber frame 32 mounted on the back plate; wherein,
the back plate includes: a bottom plate 10, a side plate 11 located at the periphery of the bottom plate 10 and fixedly connected with the peripheral edge of the bottom plate 10 to form a receiving groove, at least one first bend 13 is provided at one end of the side plate 11 far away from the bottom plate 10, each first bend 13 comprises: the first folded edge 14 is fixedly connected with one end, far away from the bottom plate 10, of the side plate 11, and the second folded edge 15 is fixedly connected with one end, far away from the side plate 11, of the first folded edge 14, wherein the second folded edge 15 is respectively perpendicular to the first folded edge 14 and the bottom plate 10, and one end, far away from the first folded edge 14, of the second folded edge 15 faces back to the bottom plate 10;
the diffusion plate is positioned in the accommodating groove of the back plate, the periphery of the diffusion plate 20 is overlapped on the first folded edge 14, and an expansion gap a is reserved between the diffusion plate and the second folded edge 15;
the rubber frame 32 includes: the vertical wall 33 and the transverse wall 34 perpendicularly intersecting the vertical wall 33, wherein the vertical wall 33 is attached and fixedly connected with the second flange 15, the transverse wall 34 covers the edge of the diffuser plate 20, and the surface of the transverse wall 34 facing the bottom plate 10 is abutted against the end surface of the second flange 15.
In the above embodiment, at least one first bend 13 is provided at an end of the side panel 11 remote from the bottom panel 10, each first bend 13 comprising: the first and second flanges 14 and 15, which are perpendicular to each other at one end, allow an angular error of ± 2 ° between the first and second flanges 14 and 15 in consideration of a machining error and convenience in subsequent assembly. The periphery of the diffuser 20 is overlapped on the first flange 14 around the diffuser, and a certain expansion gap a is required to be reserved between the edge of the diffuser 20 and the second flange 15 in the horizontal direction (the direction parallel to the bottom plate 10) so as to avoid the diffuser 20 from being pressed against the second flange 15 after being expanded to cause wrinkles; the vertical wall 33 of the rubber frame 32 is attached to the vertical surface of the second flange 15 and can be fixedly connected with the second flange 15 through screws, and the bottom surface of the transverse wall 34 of the rubber frame 32 is abutted to the upper end surface of the second flange 15. In the direct-type backlight module provided in this embodiment, the adhesive surface between the second flange 15 and the vertical wall 33 of the plastic frame 32, the locking screw, and the end surface of the second flange 15 can prevent the plastic frame 32 from turning over toward the center of the bottom plate 10, so as to ensure the stability of the plastic frame 32 supporting the liquid crystal panel.
Compared with the direct type backlight module provided by the background art, because one end of the second folded edge 15, which is far away from the first folded edge 14, is back to the bottom plate 10, the contact area between the vertical wall 33 of the rubber frame 32 and the vertical surface of the second folded edge 15 is increased, the stability of the rubber frame 32 for supporting the liquid crystal panel can be ensured without the supporting ribs 31, and the space occupied by the supporting ribs 31 and the gaps between the supporting ribs 31 and the vertical wall 33 of the rubber frame can be saved; at this time, the width d of the frame 41 is only required to be greater than the sum of the expansion gap a between the diffusion plate 20 and the second flange 15 and the thickness of the vertical wall 33 of the rubber frame 32, so that the black edge of the liquid crystal panel can be shielded and the liquid crystal panel can be fixed, the width of the frame can be reduced, and the narrow frame design of the liquid crystal display device can be realized.
In specific implementation, please refer to fig. 6 and 7, in the back plate, a certain side-turning angle is formed between the bottom plate 11 and the side plate 11, so that on one hand, the light divergence of each light source (such as an LED lamp) installed on the bottom plate 10 can be improved, and on the other hand, the outer side of the back plate can be conveniently shaped, thereby improving the aesthetic property of the direct type backlight module adopting the back plate. It should be noted that the number of the side plates 11 is not limited to one, and when there are a plurality of side plates 11, the side plates 11 may be fixed on the peripheral edge of the bottom plate 10 by welding or the like, and preferably, the side plates 11 and the bottom plate 10 are of an integral structure; specifically, it is designed such that one flat plate is first stretched by means of stretching to form a back plate having a receiving groove, and then a first bend 13 is formed at an upper edge of the receiving groove by means of bending. The overall strength and the aesthetic property of the back plate can be improved.
The shape of the bottom plate 10 is related to the shape of the liquid crystal panel and the liquid crystal display device, for example, the liquid crystal panel is rectangular, and in order to improve the aesthetic property of the liquid crystal display device and facilitate installation, the bottom plate 10 is also generally rectangular, that is, the bottom plate 10 is a rectangular plate, and the side plates 11 and the bottom plate 10 form a rectangular accommodating groove.
For example, when the frame is a rectangular frame, the upper side, the left side and the right side of the rectangular frame can be designed as narrow frames, and the lower side (ground side) still remains a wide frame, in order to implement the above design, the bottom plate 10 in the back plate is a rectangular plate, the side plate 11 and the bottom plate 10 form a rectangular receiving groove, three sides of one end of the side plate 11 away from the bottom plate 10 are designed as narrow sides, and the remaining side (ground side) is designed as wide sides.
Referring to fig. 8 and with continued reference to fig. 7, in a preferred embodiment, the side plate 11 is provided with a first bend 13 at one end corresponding to three sides of the rectangular receiving groove, and a second bend 16 at one end corresponding to the remaining side, and the second bend 16 includes: the fourth folded edge 18 is fixedly connected with one end, far away from the bottom plate 10, of the side plate 11, the fourth folded edge 18 is fixedly connected with one end, far away from the side plate 11, of the fourth folded edge 18, the fourth folded edge 18 is perpendicular to the fourth folded edge 18 and the bottom plate 10 respectively, and one end, far away from the fourth folded edge 18, of the fourth folded edge 17 points to the bottom plate 10. The second bend 16 is applied to the ground side of the back plate, so that the width of the third folded edge 17 of the side is larger than the width of the first folded edge 14 of the other three sides, thereby facilitating the wiring of the circuit and better protecting the circuit in the side. It should be noted that the second fold 16 may also be stretched to form the side panel like the other three sides, and then the third fold 17 and finally the fourth fold 18 pointing perpendicularly to the base panel 10 may be formed.
With reference to fig. 4 and fig. 5, the direct-type backlight module further includes: at least one bracket 50 positioned between the diffuser plate 20 and the first flange 14, each bracket 50 being fixedly mounted on the first flange 14 to support the diffuser plate 20. Because the upper surface of the first flange 14 is a plane, after the diffusion plate 20 is overlapped on the first flange 14, the gap between the diffusion plate 20 and the first flange 14 is very small, therefore, when the vertical wall 33 of the rubber frame 32 is locked on the second flange 15 by the screw, the space left for the screw is very small, and there is a risk that one end of the screw is pressed against the diffusion plate 20, thereby causing the diffusion plate 20 to have wrinkles, and further affecting the display effect of the direct type backlight module. After the support 50 is provided, the diffusion plate 20 can be supported by the support 50, so that a larger gap is left between the diffusion plate 20 and the first folding edge 14, and the phenomenon that the diffusion plate 20 is folded due to interference between the diffusion plate 20 and a screw can be avoided.
In the above direct type backlight module, in order to fully utilize light emitted from each light source (LED lamp) mounted on the bottom plate 10, it is preferable that the direct type backlight module further comprises: the reflection sheet 60 is disposed in the receiving groove of the back plate to reflect light emitted from the light sources, so as to reflect light emitted from each light source, thereby improving the utilization rate of light emitted from each light source (LED lamp).
Referring to fig. 4 and fig. 8, an embodiment of the invention further provides a liquid crystal display device, including: in any of the direct-type backlight modules proposed in the above technical solutions, the liquid crystal panel 70 is located on the light exit surface side of the direct-type backlight module, the periphery of the liquid crystal panel 70 is overlapped on the transverse wall 34 of the glue frame 32 in the direct-type backlight module, and the frame 41 covers the peripheral edge of the liquid crystal panel 70 and is fixedly connected with the second folded edge of the back plate in the direct-type backlight module.
In the above-mentioned liquid crystal display device, because the end of the second flange 15 far away from the first flange 14 is opposite to the bottom plate 10, the contact area between the vertical wall 33 of the glue frame 32 and the vertical surface of the second flange 15 is increased, so the adhesive surface between the second flange 15 and the vertical wall 33 of the glue frame 32 and the end surface of the second flange 15 are utilized, the glue frame 32 can be prevented from turning over toward the center of the bottom plate 10, and the stability of the glue frame 32 supporting the liquid crystal panel 70 can be ensured.
It should be noted that the liquid crystal display device may be any product or component having a display function, such as a liquid crystal television, a liquid crystal display, a digital photo frame, a mobile phone, and a tablet computer.
In the foregoing description of the various embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
