Abstract

The invention discloses a bending stiffness testing method, a bending stiffness testing device and a display panel testing method. The bending stiffness testing method comprises the steps of placing asubstrate to be tested on a reference surface; fixing the position of a first edge on the reference surface; pre-pressure facing the first edge is applied to a second edge, so that the substrate to be tested is arched relative to the reference surface to have a pre-bending angle; applying test pressure towards the first edge to the second edge, so that the to-be-tested substrate is arched relative to the reference surface to have a test bending angle; and obtaining the bending stiffness of the to-be-tested substrate at the test bending angle. According to the bending stiffness test method provided by the embodiment of the invention, the problem that the bending stiffness test error of the to-be-tested substrate is relatively large due to uneven stress, uneven surface or other miscellaneous forces is relieved.

Description

technical field [0001] The invention relates to the field of stiffness testing, in particular to a bending stiffness testing method, a testing device and a testing method for a display panel. Background technique [0002] With the development of display devices, people's requirements for display devices are becoming more and more diverse. Due to its deformable and bendable characteristics, flexible display panels can meet more diverse design requirements of display devices, so flexible display panels are being widely used. [0003] The quality of the bending performance of the flexible display panel will affect the performance and quality of the display device, wherein the bending stiffness of the flexible display panel is an important parameter of its bending performance. Therefore, it is necessary to test the bending stiffness of the flexible display panel, so as to facilitate the evaluation of its bending performance. [0004] When performing a bending stiffness test on...
