The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, it is to be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention.
The direct type backlight module comprises a diffusion plate and a back plate, wherein a larger space is arranged between the diffusion plate and the back plate, one or more diffusion plate support frames are arranged between the diffusion plate and the back plate for preventing the middle of the diffusion plate from being sunken, and the diffusion plate support frames are abutted against the diffusion plate and connected with the back plate.
Referring to fig. 2, a diffuser plate support according to an embodiment of the present invention is used for supporting a diffuser plate in a backlight module, and the diffuser plate support includes a buffer portion 1, wherein when a surface of the diffuser plate is subjected to a pressure (the pressure acts on the surface of the diffuser plate perpendicularly or obliquely), the buffer portion 1 can be elastically deformed to absorb the pressure transmitted from the diffuser plate to the diffuser plate support.
According to the diffuser plate support frame provided by the embodiment of the invention, as the diffuser plate support frame comprises the buffer part 1, when the diffuser plate is subjected to the pressure vertical to the surface of the diffuser plate, the diffuser plate transmits the pressure to the diffuser plate support frame, so that the buffer part 1 is elastically deformed, and the diffuser plate support frame and the diffuser plate are prevented from being in rigid contact, therefore, the problems of deformation, bending or fracture and the like when the diffuser plate support frame is pressed or dropped and impacted can be prevented, and the problems of bracket shadow, display blue spots, screen jumping and the like can be reduced.
The structure of the diffusion plate support frame can be realized by adopting various schemes, for example, one end of a buffer part 1 is connected with a support part 2, the support part 2 is used for abutting against the diffusion plate, the other end of the buffer part 1 is connected with a base 3, and the base 3 is provided with a connecting structure for connecting with a back plate in a backlight module; as another example, similar to the above structure, the difference is: the buffer part 1 is provided between the diffusion plate and the support part 2. In the latter, the buffer part 1 directly abuts against the diffuser plate, and when the diffuser plate is slightly pressed, the buffer part 1 is squeezed to shake, so that the supporting effect of the diffuser plate supporting frame is slightly poor, therefore, preferably, the embodiment of the invention adopts the former scheme, and the buffer part 1 is arranged between the supporting part 2 and the base 3, as shown in fig. 2 to 3, so that the supporting effect of the diffuser plate supporting frame is stable.
Specifically, the buffering portion 1 in the embodiment of the present invention includes a connecting plate 11, two opposite ends of the connecting plate 11 are respectively connected to a buffering plate 12, the connecting plate 11 and the buffering plate 12 enclose a buffering space 4, the supporting portion 2 is disposed on an outer surface of the connecting plate 11, and one end of the buffering plate 12 close to an opening of the buffering space 4 is connected to the base 3, as shown in fig. 3, when the buffering plate 12 is pressed to deform, the connecting plate 11 moves toward the base 3; compared with the scheme that the buffer part 1 adopts the buffer pad, the buffer part 1 in the embodiment of the invention is provided with a larger buffer space 4, the buffer distance is longer, and larger impact can be resisted. Referring to fig. 3-4, in the embodiment of the invention, two ends of a connecting plate 11 are respectively connected with a buffer plate 12, and a supporting part 2 is arranged at the symmetrical center of the two buffer plates 12 on the connecting plate 11, so that the buffer plates on two sides of the connecting plate are uniformly stressed, and the shock resistance is better.
Optionally, the buffer plate 12 in the embodiment of the present invention is a flat plate, an included angle between the buffer plate 12 and the connecting plate 11 is an obtuse angle, and compared with an included angle between the buffer plate 12 and the connecting plate 11 which is an acute angle, the buffer space 4 enclosed by the buffer portion 1 and the base 3 is an inverted trapezoid, the buffer portion 1 in this structure is easy to shake and is not favorable for returning to the initial position, while the buffer space 4 enclosed by the buffer portion 1 and the base 3 in the embodiment of the present invention is a regular trapezoid, as shown in fig. 3, this structure is stable, and when the pressure on the diffuser plate is removed, the buffer portion 1 can be quickly returned to the initial position. In addition, the included angle between the connecting plate 11 and the buffer plates 12 at the two ends of the connecting plate is the same, the stress of the buffer plates 12 of the connecting plate 11 is uniform, and the situation that the buffer plates 12 on one side of the connecting plate 11 are easily damaged due to long-term stress is avoided.
Optionally, the buffer plate 12 in the embodiment of the present invention is a V-shaped plate, two ends of the opening of the V-shaped plate are respectively connected to the connection plate 11 and the base 3, and similarly, the openings of the V-shaped plate at two ends of the connection plate 11 are oppositely disposed, as shown in fig. 4 to 7, a solid line in fig. 6 indicates that the buffer portion is located at an initial position, a dotted line indicates a position after the buffer portion is deformed by being pressed, and when the pressure on the diffusion plate is removed, the V-shaped plate can be quickly returned to the initial position.
In order to avoid too fast rebound speed of the diffuser plate support frame, which causes the optical component and the panel to be impacted or jump out, the buffer part 1 needs to realize slow rebound, and the buffer part can be realized by reasonably selecting buffer materials and structural parameters (such as wall thickness and angle of a V-shaped plate) of the buffer part.
Based on the above embodiment, when the buffer plate 12 is a V-shaped plate, an appropriate included angle α of the buffer plate 12 can be selected according to the size of the support frame and the actual stress condition, and the included angle α of the buffer plate 12 is too small to facilitate the rebound of the buffer part 1 to the initial position; however, the included angle α of the buffer plate 12 is too large to facilitate the deformation buffer of the buffer portion 1, and therefore, preferably, referring to fig. 7, the included angle α of the buffer plate 12 in the embodiment of the present invention is greater than 90 degrees and less than or equal to 120 degrees, and the included angles α of the V-shaped plates at the two sides of the connecting plate 11 are equal to each other, so as to avoid the problem of uneven stress.
Furthermore, according to the stress condition of the actual diffuser plate support frame, the thickness range of the proper buffer part is selected, and the buffer part is small in thickness, so that the structure deformation is facilitated, the buffer effect is good, but the buffer part is easy to break off when the stress is large; the thickness of the buffer part is larger, the structural strength of the buffer part is high, but the buffer part is not beneficial to deformation buffering, therefore, preferably, when the height H of the buffer part 1 is more than or equal to 15mm, the structural deformation allowance of the buffer part 1 is larger, and the thickness T of the buffer part 1 in the embodiment of the invention is 1.2-1.5 mm; when the height H of the cushioning portion 1 satisfies: when H is more than or equal to 10mm and less than 15mm, the structural deformation allowance of the buffer part 1 is small, the value range of the thickness T of the buffer part 1 in the embodiment of the invention is 0.8 mm-1.2 mm, and the effect of quickly absorbing the pressure structural deformation is achieved by reducing the thickness of the buffer part.
The buffer part 1 can be made of materials such as polyurethane, vinyl acetate-vinyl ester copolymer, polyamide and the like, preferably, the buffer part 1 in the embodiment of the invention is made of polyamide-6 or polyamide-66, the two materials have good buffer performance, can keep stronger strength and rigidity at higher temperature, and can better realize slow rebound.
The buffer part 1, the supporting part 2 and the base 3 in the embodiment of the invention are manufactured by integral molding, in particular to be integrally injection molded, so that the installation operation of the diffuser plate support can be simplified, and the pressure applied to the diffuser plate can be more quickly transmitted to the buffer part 1.
The embodiment of the invention also discloses a direct type backlight module which comprises a diffusion plate and a back plate, wherein the diffusion plate is supported by all the diffusion plate supporting frames, the supporting part 2 is abutted against the diffusion plate, and the base 3 is connected with the back plate through a connecting structure. Since the diffuser plate support frame installed in the direct type backlight module of the present embodiment has the same structure as the support frames provided in the embodiments of the diffuser plate support frame, the two support frames can solve the same technical problem and achieve the same expected effect.
Furthermore, the embodiment of the invention also discloses a display device which comprises a direct type backlight module, wherein the direct type backlight module adopts the direct type backlight module, and the diffusion plate support frame is applied in the direct type backlight module, so that the problems of deformation, bending or fracture and the like of the diffusion plate support frame when the diffusion plate support frame is pressed or dropped and impacted can be prevented, and the problems of bracket shadow, blue spots of the display device, screen jumping and the like are reduced.
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.
