Abstract
The utility model provides a mini LED backlight unit, includes backplate, bottom plate, buckling plate, easy drawing glue, glues frame and LED lamp plate, and the backplate includes bottom plate and buckling plate, and the backplate is the rectangle structure, and the four sides of this backplate all upwards the side buckling form the buckling plate, forms the installation cavity between bottom plate and the buckling plate. The easy-to-draw glue is pasted on the inner surface of the whole back plate, the edge of the easy-to-draw glue extends to the inner edge position formed by the inner surface of the back plate and the bending plate, the lower surface of the LED lamp panel is adhered to the easy-to-draw glue, and the LED lamp panel is located in the middle of the bottom plate. Aiming at the problems that a lamp panel is difficult to detach and easy to damage when a mini LED backlight module is maintained, the easy-to-draw glue covers the upper surface of the back plate, the glue frame is directly adhered to the easy-to-draw glue, and the glue frame fixing adhesive tape on the inner side face of the glue frame and the bent portion is omitted, so that the backlight module is simpler in structure. By simplifying the backlight, the rejection rate is reduced and the production efficiency is improved.
Description
Technical Field
The invention relates to the field of LED illumination, in particular to a mini LED backlight module.
Background
At present stage mini LED board in a poor light is as described in the structure of fig. 1, including backplate 1, bond line 2, gluey frame fixed band 3, gluey frame 4 and LED lamp plate 5, adopts the problem point that this structural formula exists to lie in:
the lamp plate is difficult for demolising and fragile during maintenance, for the reason as follows:
because the frame of the current model is narrower and narrower, the area of an LED lamp panel is large for the mini LED model, and the mini LED model is adhered by easy-to-draw glue.
Meanwhile, the edge of the easy-to-draw glue is arranged right below or inside the LED lamp panel because the glue frame needs to be attached to avoid the position; when the LED lamp panel is dismantled in the mode, one corner of the lamp panel needs to be tilted firstly, so that the dismantling efficiency is low, and the LED lamp panel has damage risk.
Disclosure of Invention
The invention aims to solve the problems that a lamp panel is difficult to dismantle and easy to damage when the existing mini LED backlight module is maintained.
The mini LED backlight module is provided, and the specific technical scheme is as follows:
the utility model provides a mini LED backlight unit, includes backplate, adhesive linkage, glues frame and LED lamp plate, its characterized in that:
the back plate comprises a bottom plate, and the side edges of the bottom plate are bent towards the same side to form a bent part;
the inner surface of the bottom plate is provided with an adhesive layer which covers the whole inner surface of the bottom plate;
the LED lamp panel is adhered to the adhesive layer, and the bottom of the rubber frame is adhered to the adhesive layer;
the glue frame is provided with a surface adjacent to the inner side surface of the bent part, and the surface is attached to the inner side surface of the bent part.
Further: the bonding layer is made of easy-to-pull glue.
The invention has the beneficial effects that: aiming at the problems that a lamp panel is difficult to detach and easy to damage when a mini LED backlight module is maintained, the upper surface of the back plate is covered by the easy-to-draw glue, the glue frame is directly adhered to the easy-to-draw glue, and the glue frame fixing adhesive tape on the inner side surface of the glue frame and the bent part is omitted, so that the backlight module is simpler in structure. By simplifying the backlight, the rejection rate is reduced and the production efficiency is improved.
Drawings
FIG. 1 is a prior art block diagram;
FIG. 2 is a block diagram of the present invention;
the attached drawing in the figure illustrates a back plate 1, a bottom plate 1-1, a bending plate 1-2, easy-to-draw glue 2, a glue frame 3 and an LED lamp panel 4.
Detailed Description
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.
This embodiment is specifically shown in fig. 2:
a mini LED backlight module comprises a back plate 1, a bottom plate 1-1, a bending plate 1-2, easy-to-draw glue 2, a glue frame 3 and an LED lamp panel 4, wherein the back plate 1 comprises the bottom plate 1-1 and the bending plate 1-2, the back plate 1 is of a rectangular structure, four sides of the back plate 1 are bent upwards to form the bending plate 1-2, and an installation cavity is formed between the bottom plate 1-1 and the bending plate 1-2.
The easy-to-pull glue 2 is adhered to the inner surface of the whole back plate 1, the edge of the easy-to-pull glue 2 extends to the inner edge formed by the inner surface of the back plate 1 and the bending plate 1-2, the lower surface of the LED lamp panel 4 is adhered to the easy-to-pull glue 2, and the LED lamp panel 4 is located in the middle of the bottom plate 1-1.
The bottom of the rubber frame 3 is directly adhered to the easy-pulling rubber 2, and the outer side face of the rubber frame 3 is adhered to the inner side face of the bending plate 1-2.
By adopting the mode, when the LED lamp panel is detached, the LED lamp panel 4 does not need to be tilted, the easy-pulling glue 2 can be directly torn to take the LED lamp panel 4 out, and the damage probability of the LED lamp panel 4 is reduced.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
