Problems solved by technology

[0003] The traditional bending test equipment is to observe and test the aging performance of the flexible screen after repeated bending of the flexible screen many times, so as to judge the degree of aging of the flexible screen. There is no intuitive monitoring of the aging performance changes, so the test process may require multiple steps of bending, observation and performance testing. The test process is cumbersome, the test efficiency is low, and the accuracy of the test results is not high.

Abstract

The present invention provides a bending test device and a bending test method. The bending test device includes: a bearing platform for placing the object to be tested; The second end swings repeatedly so that the object to be tested is bent multiple times by a bending unit, the bending unit is arranged on the carrying platform; A parameter detection unit for detecting the aging parameters of the test object during the process, and the parameter detection unit is connected with the test object. The purpose of the present invention is to provide a bending test device and a bending test method, which can intuitively monitor the performance change of the test object during the repeated bending process of the flexible display screen, so that the The performance changes during the bending test process can intuitively judge the aging degree of the object to be tested, and improve the test efficiency and test result accuracy.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a bending test device and a bending test method. Background technique [0002] With the development of economy and technology, the application of display screens is becoming more and more extensive. In the display screen, because of its bendable and flexible characteristics, the flexible screen is thinner and thinner than the traditional screen, has lower power consumption, and its durability is much higher than that of the previous screen, which can reduce the probability of accidental damage to the device. At the same time, it will have a profound impact on the application of wearable devices, and in the future, flexible screens will be widely used with the continuous penetration of personal smart terminals. The bending resistance of the flexible screen is an important parameter of the flexible screen. It is related to the screen drift and no-touch characteristics of the fini...
