Then, the first part 2 and the second part 3 are fixed to each other by means of mutual welding, screw locking, rivets, gluing or joints.

In these embodiments, the shapes of the first part and the second part can be the same or different. For the case where the shapes of the first part and the second part are the same, the first part can be made by the same processing method (metal stamping forming) or the same mold If the structure of the first part and the second part are different from the second part, or the frame shown in FIG. 2A , only part of the structure of the mold needs to be changed to realize the production of the first part and the second part.

It can be seen from the above that in this embodiment, the frame body is formed by the first part and the second part as an example, but it is not limited thereto. The frame body of the present invention can be easily assembled by using at least two parts, or it can be formed by Composed of multiple parts, the combination of two adjacent parts is as above.

In addition, the present invention also provides a method for manufacturing the above-mentioned frame body by dismantling the same part into multiple parts for separate production, and then assembling them together. In this embodiment, two components are combined to form a frame or a backboard as an example, please refer to FIG. 4 , which is a flowchart of a method for manufacturing a frame according to the present invention, wherein the method includes the following steps:

First, step S11, providing a first part and a second part, the first part has a first flat plate, and the second part has a second flat plate;

Next, step S12, make the first part and the second part adjoin each other, so that the first flat plate and the second flat plate are located on the same plane, wherein the adjoining part of the first part and the second part is the overlapping part of the first part and the second part , of course, the first part and the second part can be set to be adjacent but not overlapped.

Finally, step S13 , fixing the first flat panel and the second flat panel to form a frame applied to the display device. If the first part overlaps with the second part, the overlapping parts can be fixed to each other by welding, screwing, rivets or glue. If the first part and the second part do not overlap, the third part can be used to form overlapping parts with the first part and the second part to position and fix the first part and the second part. Moreover, the third part can be disposed on one side or both sides of the plane formed by the first plate and the second plate. Wherein, the overlapping parts can be fixed to each other by means of welding, screw locking, rivets or glue.

In the present invention, two parts such as the first part and the second part are separately formed, and then the two parts are combined into a frame body required for a large-size LCD. Using this forming method, it can greatly get rid of the large-size The method of coil stamping overcomes the fetters of equipment, not only avoiding the need to purchase high-end equipment for the production of large-size iron parts, but also avoiding the flatness and size deviation caused by the production of large-size iron parts. Problems, thus conforming to the trend of large-scale design of liquid crystal displays in the future. Moreover, the molds can also be shared. Only the same mold is needed, or the first part and the second part can be produced by partial changes, and then the first part and the second part can be combined to become a large-size liquid crystal display. The backplane or frame required by the device.
