In the present application, the back frame formed by integral molding replaces the plastic frame, the back plate, the heat dissipation plate, the aluminum substrate and the like of the existing module structure, thereby eliminating the thickness of the parts, so that the frame of the module can be narrowed to the utmost extent. Or no border, and because it can be made of metal such as aluminum, it further enhances the heat dissipation effect.

Example 2

As shown in FIG. 2 , the module structure in another embodiment of the present application includes a front frame 1 , a relatively disposed and fixedly connected liquid crystal panel 10 , and a backlight module. The backlight module includes a back frame 11 and is disposed in the back frame 11 . Optical components. The back frame 11 can be integrally formed by using an aluminum material. The back frame 11 can include a side portion and a bottom portion. The side portion and the bottom portion are formed with a receiving space for accommodating the optical component, and the side portion is formed with a supporting portion for supporting the liquid crystal panel 10. The liquid crystal panel 10 is fixed to the aluminum back frame 11 by a support portion. The edge of the liquid crystal panel 10 may be flush with the outermost end surface of the side portion of the back frame 11, that is, the outermost end and the innermost end of the liquid crystal panel 10 are on the same vertical plane. At this time, the upper portion of the side portion of the back frame 11 is One plane is integrally in contact with the liquid crystal panel 10. It is also possible to form the side portion of the back frame 11 in a stepped shape, and the liquid crystal panel 10 is only in contact with a part of the side portion, that is, the step portion. In one embodiment of the present application, the width of the support portion supporting the liquid crystal panel 10 may preferably be 2-3 mm, but is not limited thereto.

In the embodiment of the present application, the front frame 1 may be disposed on one side of the liquid crystal panel 10 to fix the liquid crystal panel 10 on the back frame 11. The front frame 1, the liquid crystal panel 10, and the back frame 11 can be fixed by any existing fixing manner. For example, the front frame 1 and the back frame 11 can be fixed by screws provided on the side of the front frame 1, and the liquid crystal panel 10 can pass The double-sided tape is bonded to the support portion of the back frame 11. When the liquid crystal panel 10 is fixed by bonding, the entire portion of the liquid crystal panel 11 in contact with the support portion can be covered.

The distance of the light-emitting surface of the light source 3 from the screen display area is the same as the distance of the LED light-emitting surface of the existing module structure from the screen display area, and is the distance A, so that the LED light shadow phenomenon is not generated.

The reflector 7, the light guide plate 8, and the optical film 9 are known conventional structures, and a detailed description thereof will be omitted herein to avoid redundancy.

In this embodiment, since the back frame 11 formed by integral molding replaces the plastic frame, the back plate, the heat dissipation plate, the aluminum substrate and the like of the existing module structure, the thickness of the parts is omitted, so that the module is The frame can be narrowed to the utmost extent, at least 2 mm narrower than the frame width of the module of the prior art. Preferably, the frame width of the module of the embodiment is 6 mm or less, and since the back frame is entirely supported by aluminum, Further improve the heat dissipation effect.

FIG. 3 is a schematic structural diagram of a frameless liquid crystal module according to another embodiment of the present application. The module structure of this embodiment is substantially the same as the module structure of the above embodiment except that there is no front frame. In this way, the front frame is eliminated, so that the borderless effect can be achieved. In the case of no border, the liquid crystal panel 10 is directly bonded to the support portion of the back frame 11 by applying double-sided tape on the back side, so that the front frame 1 is not required to fix the liquid crystal panel of the liquid crystal panel 10, thereby achieving a borderless effect.

In this embodiment, an additional frame structure (front frame) is not used to fix the liquid crystal panel of the liquid crystal panel, and the integrated connection between the liquid crystal panel and the aluminum base frame is achieved by bonding, and the entire liquid crystal module has no frame and is enlarged. The effective display area of the liquid crystal module makes the liquid crystal module more beautiful, and also makes the super Large-size LCD screens are more feasible and convenient for splicing, and the effect is better.

In addition, the present application also provides a liquid crystal display device including the liquid crystal module of the above embodiment.
