The embodiment of the invention discloses a Mini-LED backlight module to avoid irreversible damage to a reflector plate caused by splicing and deformation of lamp panel monomers.
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.
Referring to fig. 1-2, fig. 1 is a schematic structural diagram of a Mini-LED backlight module according to an embodiment of the present invention; fig. 2 is a schematic cross-sectional view corresponding to fig. 1.
In one embodiment, the Mini-LED backlight module provided by the invention comprises a back plate 1, a lamp plate 3 and a reflector plate 2.
The back plate 1 is located at the bottom layer to support the installation lamp panel 3. The specific structure of the back plate 1 can be set by referring to the back plate 1 in a common Mini-LED backlight module, and details are not repeated here.
The lamp panel 3 is laid on the backboard 1, and the lamp panel 3 comprises a plurality of lamp panel monomers which are butted and arranged. The number of LEDs in the Mini-LED backlight area reaches thousands or even tens of thousands, and because the Mini-LED backlight area is limited by a proofing machine, Mini-LED products are all small-size lamp panel monomers, and then the small-size lamp panel monomers are spliced into the large-size lamp panel 3. The number of the specific lamp panel monomers can be set according to needs, and the specific limitation is not made here. And the plurality of blocks comprise two blocks or more than two blocks. The single splicing mode of polylith lamp plate can be single row multiseriate according to the size requirement and splice, also can be multirow multiseriate concatenation. The laying mode of specific lamp plate 3 can refer to the prior art, and is not repeated here.
The reflector plate 2 is laid on the lamp panel 3, and the reflector plate 2 is folded at the splicing position of two adjacent lamp panel monomers. The reflector plate 2 is laid on the lamp panel 3 and can be adhered to the lamp panel 3 through gum and the like, and the reflector plate 2 is correspondingly provided with avoiding holes corresponding to the positions of the lamp beads 31 on the lamp panel 3. The reflection sheet 2 may be a whole structure or a spliced structure as needed. The reflector plate 2 adopts a folding structure at the splicing position of two adjacent lamp panel monomers, namely the splicing seam 32, and the specific folding mode can be set as required. It should be noted that, the non-planar structure that the folded structure formed through buckling promptly, and then when folding department both sides and 2 parts of reflector plate of different lamp plate monomer fixed connection took place relative displacement, the corresponding motion of folded part was in order to offset this displacement, avoided causing the dragging to 2 parts of reflector plate with different lamp plate monomer fixed connection.
By applying the Mini-LED backlight module provided by the invention, because the reflection sheet 2 at the splicing part of the adjacent lamp panel monomers adopts a folding design, even if the lamp panel monomers generate micro deformation due to transportation and other reasons, the folding part of the reflection sheet 2 can well move along with the deformation of the lamp panel monomers, thereby avoiding the irreversible damage of the reflection sheet 2 caused by the deformation of the splicing seams 32 of the lamp panel monomers, ensuring the quality of the reflection sheet 2 and prolonging the service life of the reflection sheet.
Specifically, reflector plate 2 is upwards rolled over by the level earlier by a lateral opposite side of two adjacent lamp plate monomer's concatenation department and forms first inclined plane 21, rolls over downwards again and forms second inclined plane 22, rolls over to the level again, and concatenation department is located first inclined plane 21 and second inclined plane 22 below. That is, as shown in fig. 2, taking the left side to the right side as an example, the folding of reflector plate 2 is that the left side of the splicing position is firstly folded upwards by the level to form first inclined plane 21, and then folded downwards to the right of the splicing position and form second inclined plane 22, and then folded to the level to lay along the lamp panel monomer on the right of the splicing position. By the above folding, a convex structure is formed to accommodate the deformation of the patchwork 32.
Further, the first inclined surface 21 and the second inclined surface 22 are symmetrical with respect to a line connecting the two. The symmetrical arrangement is adopted, so that the first inclined surface 21 and the second inclined surface 22 are firmer. The first inclined surface 21 and the second inclined surface 22 are not limited to be symmetrically arranged, and the length of the first inclined surface 21 may be larger or smaller than that of the second inclined surface 22.
Specifically, the splice is disposed corresponding to a connecting line between the first inclined surface 21 and the second inclined surface 22. I.e. the first inclined surface 21 and the second inclined surface 22 are symmetrical about the seam 32, so that the folded structure can better adapt to the deformation at the splice. According to the needs, the splicing part can also be positioned on the left side or the right side of the connecting line, and the splicing part can be correspondingly arranged according to specific conditions.
For the first inclined plane 21 and the second inclined plane 22, specifically, the included angle range of the first inclined plane 21 and the lamp panel 3 is 10 degrees to 60 degrees, and the included angle range of the second inclined plane 22 and the lamp panel 3 is 10 degrees to 60 degrees. Taking fig. 2 as an example, the left-right reflector plate 2 is folded upward to form a first inclined plane 21 from the left side of the joint, and then folded downward to the right side of the joint to form a second inclined plane 22, the included angle between the first inclined plane 21 and the lamp panel 3 on the right side of the first inclined plane 21 is the angle between the first inclined plane 21 and the lamp panel 3 on the right side of the first inclined plane, and the included angle between the second inclined plane 22 and the lamp panel 3 on the left side of the second inclined plane 22 is the angle between the second inclined plane 22 and the lamp panel 3 on the left side of the second inclined. Through above-mentioned angle setting, can reflect the light that lamp pearl 31 sent to diffuser plate 4 through beta structure, make light distribution more even.
Specifically, a plurality of lamp beads 31 are arranged on each lamp panel 3 in an array manner. The lamp beads 31 are arranged in an array mode, so that the emitted light rays are more uniform. The lamp beads 31 can also be arranged in other arrangement modes as required.
In the above embodiments, the diffuser plate 4 is disposed above the reflector plate 2, and the height of the folded portion of the reflector plate 2 is lower than the distance from the lamp panel 3 to the diffuser plate 4. Through the setting of diffuser plate 4 for the better diffusion of light that lamp pearl 31 sent, it is more even to distribute. The structure of the diffusion plate 4 can refer to the arrangement of the diffusion plate 4 in the conventional Mini-LED backlight module, and is not limited herein. If necessary, a holder fixedly connected to the back plate 1 may be provided, and the diffuser plate 4 may be fixedly attached to the holder. The folding department height of reflector plate 2 is less than the distance of lamp plate 3 to diffuser plate 4 to the folding of reflector plate 2 has been avoided causing the interference to diffuser plate 4's setting.
Furthermore, the lower surface of the diffusion plate 4 is provided with a fluorescent material strip corresponding to the splicing position of the two adjacent lamp panel monomers. The fluorescent material strip and the strip-shaped structure formed by the fluorescent material may be made of a fluorescent material that is conventional in the art, and is not limited herein. Through increasing fluorescent material at 3 splice departments top diffuser plates 4 lower surfaces of lamp plate, carry out optical compensation to the dark band that splice department caused, make splice department top region more natural with the 3 top optics transition of normal lamp plate, alleviate the influence of dark band to optical quality in a poor light, effectively improved optical quality.
Specifically, the fluorescent material strip is formed by fluorescent material dots distributed in a dispersion shape, and the distribution density of the fluorescent material dots is reduced from a position close to a center line of a splicing position to a position far away from the center line. That is, the lower surface of the diffusion plate 4 is provided with fluorescent material dots distributed in dispersed dots corresponding to the splicing positions of the lamp panel monomers, and the fluorescent material dots form the fluorescent material strip. Because the dark band that concatenation department caused is more obvious in concatenation department central line position, so set up the distribution density of phosphor material point and reduce to the position of keeping away from the central line by the position that is close to concatenation department central line to the light filling effect to the concatenation department centre is strong, and the light filling effect at edge is weak, makes concatenation department top region and normal lamp plate 3 top optical transition more natural, has further improved optical quality.
Specifically, the width of the strip of fluorescent material is greater than the width of the splice 32 at the splice. If the width of the seam 32 is 10mm, the width of the fluorescent material strip is larger than 10mm, so that the light supplement effect is ensured. Further, the width of the fluorescent material strip is 3-5 times of the width of the seam 32, and the center line of the fluorescent material strip is collinear with the center line of the seam 32. Taking the seam as 10mm wide as an example, the fluorescent material strips respectively extend to two sides by taking the center line of the seam 32 as the center line to form the fluorescent material strips with the width of 30-50 mm. So set up, can guarantee that 2 top regions of concatenation department and the natural transition of 5 top optics of normal lamp plate. In the case where the fluorescent material tape is formed of fluorescent material dots distributed in a dispersed pattern, the fluorescent material dots are distributed more intensively as they approach the patchwork.
In the above embodiments, the strip of fluorescent material is coated or wet-printed onto the diffuser plate 4. By coating or wet printing, reliable molding of the fluorescent material on the diffusion plate 4 is ensured. For the specific coating or wet printing process and operation, reference is made to the prior art, which is not described herein again.
