Hook-face displayer back plate forming equipment and method

Abstract

The invention provides hook-face displayer back plate forming equipment. The hook-face displayer back plate forming equipment comprises an upper die and a lower die. The upper die comprises a plurality of segmented punching heads and a material pressing plate, wherein the working surfaces of the segmented punching heads are hook faces, and the material pressing plate is arranged on the outer sides of the segmented punching heads. The working surface of the lower die is a hook face matched with the working surfaces of the segmented punching heads. The edge of the lower die and the material pressing plate are matched to fix a back plate raw material. The working surfaces of all the segmented punching heads are sequentially attached to the working surface of the lower die to punch the back plate raw material, so that the back plate raw material is subjected to plastic deformation. The invention further provides a hook-face displayer back plate forming method. A workpiece is punched through the segmented punching heads in sequence, workpiece feeding is easy to control, the workpiece is uniformly stretched, an obtained hook-face back plate is thin and has certain strength, and the precise hook face can be maintained.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a forming device and a forming method for a curved display backplane. Background technique [0002] With the continuous development of display technology, the ultra-thin design of curved displays has become the latest research direction in the field of display technology. Generally, a curved display includes original components such as a backplane, a backlight unit, and a display panel, wherein the backlight unit and the display panel are fixed on the backplane with a preset curved state, so as to maintain the same curvature as the backplane. Therefore, how to design and process the backplane so that it has the characteristics of thinness and lightness while maintaining the curvature has become a hot topic in the research of curved displays. [0003] In the prior art, the method of forming the backplane of a curved display is to use a stamping device with a punch and a die to f...
