Description

Technical Field

[0001] The utility model relates to the technical field of backlight modules, in particular to an all-in-one backlight module. Background Art

[0002] Display products such as monitors and televisions are constantly improving their pursuit of product appearance while satisfying the display effect and performance. Lightweight, low-cost, and easy to maintain products have become a trend. The existing backlight modules all use a set of back panels (plastic back shells) as the main structure. The backlight materials can only be assembled from the inside of the machine. The disassembly and assembly workload is large and the internal backlight components are easily damaged. In addition, since it only relies on the support of the plastic back panel, its hardness is poor and it is easily affected by external forces. Utility Model Content

[0003] The utility model aims to overcome at least one defect of the above-mentioned prior art and provide an all-in-one backlight module to achieve the purpose of convenient disassembly and assembly, high overall hardness and strong stability.

[0004] The utility model provides an integrated machine backlight module, comprising a top side end and a bottom side end; comprising a liquid crystal panel, a diaphragm group, a light guide plate, a reflective sheet, a radiator and an iron back plate in sequence; the bottom side end of the integrated machine backlight module is also provided with a lower side bar and a light bar, and the radiator encloses the light bar and the light guide plate at the bottom side end to form a heat dissipation space; the lower side bar is L-shaped; one side is attached to the liquid crystal panel; the bottom is used to fix the radiator; the other end is connected to the iron back plate to achieve the fixation of the bottom side end.

[0005] The utility model designs a new backlight module structure and process to optimize assembly efficiency and cost. At the same time, as the peripheral and rear appearance structure of a television or display, an iron back plate is used as an appearance part to play a supporting role and also to assist in heat dissipation. The liquid crystal panel of the utility model is exposed, and glass is used as a light guide material. The reflective sheet, the glass light guide plate and the optical film are first wrapped with an integral wrapping tape to form an optical component, and then the liquid crystal panel is attached to the optical component to form a complete liquid crystal film group. The liquid crystal film group is then fixed to the iron back plate by a snap-fit ​​method, which is convenient for disassembly and assembly. The utility model also designs an L-shaped lower edge strip on the ground side, which can wrap the bottom of the entire liquid crystal film group to achieve quick disassembly and assembly.

[0006] Furthermore, the top side end is provided with a hook and a plastic frame; the hook includes a hook body and a connecting portion; the connecting portion is fixed to the iron back plate; and the hook body is connected to the plastic frame.

[0007] Preferably, the entire liquid crystal module of the utility model is clamped to the iron back plate by the cooperation of the plastic frame and the hook of the sheet metal material. This structural method is based on the toughness and resilience of the sheet metal and plastic to achieve the design concept of easy installation and quick disassembly, without the use of screws, saving materials and processes, and realizing a universal product form for the backlight source, which can be applied to the display product design of all edge-lit backlight modules.

[0008] More preferably, the iron back plate is in a 7-shape; the top is attached to the top side of the all-in-one backlight module; the bottom is connected to the bottom side bar. Therefore, the iron back plate of the utility model encloses the top end of the backlight module, and the bottom end is fixed by the bottom side bar. When assembling, the whole can be inserted from the top side to the iron back plate and hooked, and disassembly is also convenient and quick.

[0009] Furthermore, the plastic frame includes an embedding portion, a first bending portion, a second bending portion, a third bending portion and a hook cap; the embedding portion, the first bending portion and the second bending portion form an embedding space with an opening on one side, and the embedding space encloses and fixes the diaphragm group, the light guide plate, the reflective sheet and the heat sink; the hook cap is connected to the hook body.

[0010] Another inventive point of the utility model is the design of the plastic frame. Since the iron back plate and the plastic frame cannot be directly connected, the utility model designs a connection method of hooks and plastic frame buckles, which can realize the rapid fixation of the iron back plate and the plastic frame, and the connection is detachable. The utility model design uses the iron back plate, buckles, and frames as the main structure, and uses an integrated wrapping tape to fix the reflector, glass light guide plate, optical film, and heat sink into an optical component, and then the optical component is clipped into the frame of the lower side bar, and then the liquid crystal panel is attached to the surface of the frame, and finally the liquid crystal module is fixed with the iron back plate by a buckle method, so as to achieve ultra-thin, low cost, and no need to open a mold, forming an easy-to-assemble, easy-to-disassemble, and beautifully designed all-in-one display product.

[0011] Furthermore, the cross section of the hook cap is trapezoidal, the upper bottom surface of the trapezoid fits with the inner side surface of the iron back plate; the fitting surface is a plane, which improves the stability of the fitting. The lower bottom surface extends upward to form an embedding end, which is connected to the hook body.

[0012] Furthermore, the hook body is V-shaped, and the inner side is used to embed the embedding end.

[0013] Furthermore, double-sided foam glue is provided between the embedding portion and the liquid crystal panel. Therefore, the optical module of the utility model adopts a pasting method, does not need to be fixed with screws, and is more convenient to disassemble and assemble.

[0014] Furthermore, the top end of the connection portion is welded to the inner side surface of the iron back plate and / or the side edge of the connection portion is adhered to the inner side surface of the iron back plate.

[0015] Furthermore, the radiator is an iron radiator; the iron radiator includes a fitting portion and an enclosure portion; the fitting portion is fitted and fixed to the reflector; the enclosure portion is a semi-enclosed structure with one side open, forming a heat dissipation space for heat dissipation of the light bar. There is also a certain space between the iron radiator and the iron back plate to achieve heat dissipation, and the heat dissipation space is mainly used to concentrate the heat dissipation of the light bar.

[0016] Furthermore, the middle part of the iron back plate is protruding to form a heat dissipation space. The utility model adopts the iron back plate to increase the support strength of the entire optical module and also play a role in assisting heat dissipation.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] The utility model design uses an iron back plate, buckles, and a frame as the main structure, and fixes the reflector, glass light guide plate, optical film, and radiator into an optical component using an integrated wrapping tape, and then the optical component is snapped into the frame of the lower side bar, and then the liquid crystal panel is attached to the surface of the frame, and finally the liquid crystal module is fixed to the iron back plate by buckles, so as to achieve ultra-thinness, low cost, and no need for mold opening, forming an all-in-one display product that is easy to assemble, easy to disassemble, and has a beautiful appearance.
