Problems solved by technology

Due to the characteristics of sheet metal materials, there will be springback deformation and aging deformation of the parts after integral molding, which makes it difficult to achieve accurate curved surfaces
At present, there is no perfect solution in the whole industry. Generally, the mold is adjusted at any time to control the accuracy of the curvature of the part, which increases the manufacturing cost a lot.

Abstract

The invention relates to a cambered displayer backboard manufacturing method and structure. The cambered displayer backboard manufacturing method and structure can prevent rebound deformation of a cambered backboard. The method involves a bearing plate, and comprises the following steps that (a), the bearing plate and a connection plate are selected; (b), bearing plate installing holes are formed in the bearing plate at same intervals; (c), connection plate installing holes are formed in the connection plate at same intervals; (d), fastening screws are arranged on the bearing plate installing holes of the bearing plate and the connection plate installing holes of the connection plate, it is guaranteed that the distance between the bearing plate and the connection plate is h, the bearing plate and the connection plate are firmly fixed through a tool, a fastening device, the fastening screws and fastening nuts, the bearing plate and the connection plate naturally bend, and a bearing plate curved surface with the radian equal to the circular arc radius R of the bearing plate is formed. The cambered displayer backboard manufacturing method is applied to cambered backboard process for manufacturing cambered displayers.

Description

technical field [0001] The invention relates to the field of manufacturing curved displays, in particular to a method and structure for manufacturing a curved display backplane. Background technique [0002] At present, displays are developing towards ultra-thin and curved surfaces. In particular, the development of curved surface display modules is entering a white-hot stage, and major TV manufacturers and liquid crystal display manufacturers are strengthening research on curved surface technology. It is expected that in 2014, curved TVs on the market will become mainstream. The key part of the curved display module is the curved backplane, and the radian of the curved surface is guaranteed by the accuracy of the curved backplane. In order to save costs, curved backplanes are generally processed with sheet metal materials. Currently, molds are used for integral molding in the industry. Due to the characteristics of the sheet metal material, there will be springback defor...
