Measuring device and measuring method

Abstract

The invention relates to a measuring device, which is used for measuring bending parameters of a bendable area of a flexible display panel and comprises: a first limiting and fixing assembly, whereinthe first limiting and fixing assembly comprises a first limiting plate capable of being connected with the first non-bending area, a second limiting plate capable of being connected with the second non-bending area, and a adjusting piece which can adjust the distance between the first limiting plate and the second limiting plate to be a preset distance; a second limiting and fixing assembly whichcomprises an adjusting structure capable of adjusting the bending radius of the bendable area and a sensing structure used for sensing the positions of the two opposite sides of the bendable area toobtain the current bending radius information of the bendable area, wherein the first direction is parallel to the direction from the first non-bending area to the bendable area; a measuring assemblywhich is used for measuring the first bending length of the bendable area in the first direction when the flexible display panel is in the bent state. The invention also relates to a measuring method.

Description

technical field [0001] The invention relates to the technical field of manufacturing flexible display products, in particular to a measuring device and a measuring method. Background technique [0002] With the development of communication technology, mobile display devices such as mobile phones and smart wearable devices are widely used. In order to ensure the portability of display devices, foldable display devices have become a trend. For the panel (display panel) inwardly curved drop-shaped structure, when the module stacking structure is determined, the screen distance H after bending, the bending radius R, and the bending border (boundary) length L are one-to-one correspondence, that is, locked Two of them determine the third. However, the relationship between the screen distance H after bending, the bending radius R, and the bending border length L is complex and nonlinear, which cannot be obtained by calculation. A qualitative measurement method is required, and the...
