Problems solved by technology

As the resolution doubles, the number of flexible circuit boards displayed on the liquid crystal panel that drives the liquid crystal display will also double, so that the flexible circuit board will be densely distributed on the source of the liquid crystal panel, resulting in limited mechanism design, such as Screw distribution settings, etc.

Embodiment 1

[0022] figure 1 is a schematic structural view of a liquid crystal display according to Embodiment 1 of the present invention.

[0023] refer to figure 1 The liquid crystal display provided by Embodiment 1 of the present invention mainly includes a liquid crystal panel 10 and a backlight module 20, wherein the liquid crystal panel 10 is arranged on the backlight module 20 or the backlight module 20 is arranged opposite to the liquid crystal panel 10, and the backlight module Group 20 is to provide the display light source to the liquid crystal panel 10, so that the liquid crystal panel 10 displays images by the light provided by the backlight module 20, and the specific fixing method of the liquid crystal panel 10 and the backlight module 20 will be carried out on the backlight module 20 below. When describing in detail, explain it together. Since in the present invention, the liquid crystal panel 10 can be a liquid crystal panel in the prior art, please refer to the relevan...

Embodiment 2

[0034] In this embodiment, only the differences from Embodiment 1 will be described, and the same content as Embodiment 1 will not be repeated here. image 3 is a schematic structural view of a liquid crystal display according to Embodiment 2 of the present invention.

[0035] refer to image 3 The difference between Embodiment 2 and Embodiment 1 is that in order to realize the fixing of the liquid crystal panel 10 and the backlight module 20, the liquid crystal display further includes an outer frame 70, wherein the frame edge 71 of the outer frame 70 connects the liquid crystal panel 10 Pressed on the backlight module 20, the side wall 72 of the outer frame 70 is provided with a locking hole 721, and the side wall 231 of the bracket 23 is provided with a hook 2311 corresponding to the locking hole 721. The hook 2311 and the locking hole 721 Corresponding locking and fixed connection, so that the side wall 72 of the outer frame 70 is fixedly connected with the side wall 231 ...

Embodiment 3

[0037] Figure 4 is a schematic structural view of a liquid crystal display according to Embodiment 3 of the present invention.

[0038] refer to Figure 4 The difference between embodiment 3 and embodiment 1 is: in order to accommodate the multiplied flexible circuit board 30 and the printed circuit board 40 connected with the flexible circuit board 30, the backlight module 20 according to embodiment 3 of the present invention Also comprise support 23, back frame 24 is arranged on support 23 like this and is fixedly connected with support 23, and the part near the sidewall 241 of back frame 24 of the bottom plate 232 of support 23 is along the bottom plate 242 far away from back frame 24. direction (the direction opposite to the y direction in the figure) protrudes to form an accommodating cavity 50 , which can be used to accommodate multiplied flexible circuit boards 30 and printed circuit boards 40 .

[0039] In addition, since the accommodation cavity 50 is formed betwee...

Abstract

The invention discloses a backlight module and a liquid crystal display. The backlight module includes a back frame (24) and a bracket (23), wherein the back frame (24) is disposed on the bracket (23) and is fixedly connected to the bracket (23), and the A receiving cavity (50) is formed between the back frame (24) and the bracket (23). The receiving cavity (50) is used to accommodate the flexible circuit board (30) and connect with the flexible circuit board (30). of printed circuit boards (40). The present invention adds a bracket outside the back frame, so that a receiving cavity is formed between the back frame and the bracket to accommodate the doubled number of flexible circuit boards and printed circuit boards, thereby realizing high-definition display of the liquid crystal display while improving the mechanical properties of the liquid crystal display. reliability.

Description

technical field [0001] The invention relates to the field of liquid crystal display; more specifically, it relates to a backlight module and a liquid crystal display. Background technique [0002] Liquid crystal display (Liquid Crystal Display, LCD) has been more and more widely used due to its many advantages such as thin body, power saving, low radiation, soft picture and not hurting eyes. With people's continuous pursuit of high-definition picture quality, the introduction of LCD monitors with a resolution of 4K has brought unprecedented high-quality visual enjoyment to consumers, and such high-quality LCD monitors are becoming more and more popular. welcome. Therefore, in order to introduce higher-resolution liquid crystal displays, some manufacturers are conducting research on liquid crystal displays with a resolution as high as 8K. [0003] With the continuous development of technology, liquid crystal displays with higher resolution will be produced. As the resoluti...
