Abstract

The invention discloses a curling test method and device. The curling test method comprises steps that when a curling test signal is received, a movable mechanism is controlled for moving in a set direction and a curling shaft is controlled to rotate around the axis so as to stretch or curl a to-be-tested flexible board, and the movable mechanism is used for fixing a first end of the to-be-testedflexible board, the curling shaft is used for fixing a second end, opposite to the first end, of the to-be-tested flexible board, and the set direction is perpendicular to the axis direction of the curling shaft; in the process of curling or stretching the to-be-tested flexible board, the moving speed of the movable mechanism and / or the angular speed of the curling shaft are / is adjusted so that the stretching and curling speed of the to-be-tested flexible board located on an outermost ring of the curling shaft is equal to the moving speed of the movable mechanism. The curling test method is advantaged in that problems that accuracy of the curling test is reduced, and a flexible display device and the curling test device are easy to damage are solved.

Description

technical field

[0001] The embodiments of the present invention relate to the technical field of crimp testing, and in particular, to a crimp testing method and equipment. Background technique

[0002] In the field of displays, flexible display devices that can be bent or rolled are one of the development directions of next-generation display technologies. The curl life and curl reliability are one of the important properties to measure the quality of such a flexible display device.

[0003] However, in the process of curling the flexible display device using the existing curl test method, the flexible display device may be over-tensioned or unable to keep straight, resulting in a decrease in the accuracy of the curl test, and the flexible display Equipment as well as crimp testing equipment are susceptible to damage. Contents of the invention

[0004] In view of this, the object of the present invention is to propose a curl testing method and equipment to solve the prob...
