Problems solved by technology

This method has a disadvantage. It is more troublesome to apply the sealant, and the cutting section of the glass edge of the liquid crystal module is not smooth, which may easily cause the sealant to not adhere firmly and there is a risk of falling off.
[0003] Since the glass of the LCD module without a front frame is already close to the outermost edge, the conventional method is to design an edge-wrapped shell with a relatively simple appearance design, as shown in the side shell 3 in the figure
Existing frameless liquid crystal display modules cannot provide a variety of overall appearance requirements
In addition, the shell of the whole machine adopts a hemming structure, and the shell is locked to the back frame of the module, which may easily cause the shell to turn outward and cause uneven gaps.
There needs to be a gap D1 between the side shell and the module, which is not conducive to reducing the frame

Embodiment 1

[0023] Such as figure 2 As shown, the liquid crystal display in this embodiment includes a liquid crystal display module 10 and a back frame 20, wherein the liquid crystal display module 10 is composed of a liquid crystal module 11 and a backlight module 12, and also includes a middle frame 30, wherein the middle frame 30 is fixed by side walls 31 and The horizontal wall 32 connected to the side wall 31 forms a T-shape. The horizontal wall 32 divides the side wall 31 into a front side wall 311 and a rear side wall 312. As shown in the figure, the liquid crystal module 11 is fixed on the horizontal wall 32 and its The side corresponds to the inner side of the front side wall 311, and can also be as figure 1 As shown, a sealant (not shown) is coated on the edge A of the liquid crystal module 11, wherein the liquid crystal module 11 is connected to the horizontal wall 32 of the middle frame 30 by pasting hair on the lower glass substrate 13 of the liquid crystal module 11. Bubb...

Embodiment 2

[0028] The structure of this embodiment is as image 3 As shown, different from Embodiment 1, the side wall 31 of the middle frame 30 is composed of an integrally formed front side wall 311 and an indented rear side wall 312, that is, the rear side wall 312 and the front side wall 311 form a step, and at the same time It also includes a side outer frame 40, the side outer frame 40 is composed of a side frame 41 and a bottom frame 42 which are integrally connected vertically, wherein the side frame 41 is connected to the step, and the bottom frame 42 is fixedly connected to the back frame 20 , the fixed connection method can be screw connection or riveting. In order to achieve an overall uniform visual effect, the outer surface of the side frame 40 in this embodiment is on the same plane as the outer surface of the front side wall 311 . This structural design can prevent the front side wall 311 from warping outward, because when the front side wall 311 is warped outward, it wi...

Embodiment 3

[0030] see Figure 4 This embodiment differs from Embodiment 2 in that the step of the middle frame 30 also includes a groove 33 indented in the direction of the front side wall 311 along the surface of the rear side wall 312, and correspondingly, the end of the side outer frame 40 is provided with There is a convex edge 43 . This structure can strengthen the combination of the side outer frame 40 and the middle frame 30 without misalignment and the like, and the effect on the front side wall 311 is the same as that of Embodiment 2, and will not be repeated here.

Abstract

A narrow frame structure of a liquid crystal display comprises a middle frame (30), where the middle frame (30) is formed of a sidewall (31) and a horizontal wall (32) fixedly connected to the sidewall (31), the horizontal wall (32) divides the sidewall (31) into a front sidewall (311) and a rear sidewall (312), a liquid crystal module (11) of the liquid crystal display is fixed on the horizontal wall (32), a lateral side of the liquid crystal module (11) corresponds to an inner side of the front sidewall (311), the rear sidewall (312) is fixedly connected to a back frame (20) of the liquid crystal display, and a backlight module (12) of the liquid crystal display is fixed on the back frame (20). A liquid crystal display having a narrow frame comprises the narrow frame structure. The narrow frame structure can effectively achieve an objective of a narrow frame, and can further effectively prevent warp and deformation of the front sidewall (311) of the middle frame (30).

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to the narrow frame structure of the liquid crystal display. Background technique [0002] Nowadays, liquid crystal displays with narrow frame structures have become a trend. Existing liquid crystal displays usually include a front frame, which is mainly used to hold down the liquid crystal module and prevent the liquid crystal module from being detached. The whole machine with a narrow front frame design generally adopts a wrap-around appearance scheme, that is, the side shell is used to wrap the LCD module. With the development of display technology, the liquid crystal display without front frame shows a more fashionable appearance. figure 1 It is a schematic diagram of the overall design of the liquid crystal display module without a front frame. Since there is no front frame, the edge of the liquid crystal module 1 is directly exposed to the outside, and the gla...
