Problems solved by technology

The whole process needs to be flipped four times. For TVs over 60 inches, the length and width are too large. If you still use flat and flipped assembly, the operating distance will exceed the ergonomic comfort distance, so the production efficiency will be reduced. , and if the size is too large, if it is turned over many times, it will increase the risk of cracking the liquid crystal group

Embodiment 1

[0043] In this embodiment, the present invention is described by taking a super large liquid crystal display module (above 60 inches) of the direct-lit type as an example.

[0044] Such as Figure 4 As shown, the assembly of a super large liquid crystal display module needs to assemble the backplane first, and the backplane 310 is processed into a whole backplane 310 by riveting, welding, screwing and other processes for multiple block parts, so as to provide the liquid crystal display module. enough strength. The backplane 310 in this embodiment is formed by splicing a plurality of splicing blocks of rectangular structure, and the figure shows only one kind of spliced ​​backplane structure, but this patent should not be limited to this exemplary structure.

[0045] Such as Figure 5 As shown, two parallel fixed beams 311 are also arranged on the back side of the back plate 310. The two parallel fixed beams 311 can improve the strength of the spliced ​​back plate, and at the...

Embodiment 2

[0061] The liquid crystal display module in this embodiment adopts side-incoming light, and the difference from the first embodiment is that the light source assembly is fixed on the side wall of the back plate, and the light guide plate is used to convert the side-incoming light into a surface light source, while the first embodiment One of the light source components is arranged on the surface of the backplane.

[0062] Such as image 3 Shown, assembly process of the present invention can be summarized as following steps:

[0063] a1. Erect and fix the backboard, install the light source components on the backboard, and light it up for inspection;

[0064] a2. Install reflector and diffuser;

[0065] a3. Install optical diaphragm and middle frame;

[0066] a4. Lay the backlight module flat, install the LCD panel assembly and the front frame;

[0067] a5, erect and fixed, and lock various circuit boards;

[0068] a6. Check the screen.

[0069] Among them, in steps a1-a3...

Abstract

The invention discloses a liquid crystal display module and a packaging method. The liquid crystal display module comprises a back plate, wherein the back plate is provided with a fixing beam used for fixing the back plate erectly. As the back plate of the liquid crystal display module is provided with the fixing beam used for providing support to fix the back plate erectly, the back plate can be erected during the mounting process per se for the installation of a backlight module and a liquid crystal display component. Therefore, in the assembling process of the liquid crystal display module, a two-overturning process, that means, a process of mounting the liquid crystal display component horizontally and remounting a circuit board erectly, is only necessary when the liquid crystal display component is assembled, and the reduction of the overturning time decreases damage probability of the liquid crystal display component in installation during the assembling process; and as the erect mounting way is adopted for assembling the backlight module, a worker can operate in a standing manner, a wider reachable distance of the operation is can be obtained, and the operating distance can be enabled to adapt to an ergonomic and comfortable distance so as to improve the production efficiency.

Description

technical field [0001] The invention relates to the field of liquid crystal display devices, in particular to a liquid crystal display module and an assembly method thereof. Background technique [0002] Liquid crystal display is widely used in people's life and work because of its thinness and large display size. The structure of liquid crystal display is generally divided into backlight group, liquid crystal panel assembly, front frame, circuit board and so on. [0003] Such as figure 1 As shown, the backlight module 101 includes a light source assembly 110, a reflector 120, a light guide plate (or diffusion plate) 130, a plurality of optical films 140, a middle frame 150 for fixing the optical films, and a power board 160 for controlling the light source assembly 110. . The liquid crystal panel assembly 170 includes a liquid crystal panel 171 , a flexible circuit board 172 , and a signal timing control circuit board 173 . The front frame 180 is used to fix the liquid c...
