Description

Technical Field

[0001] The present invention relates to the technical field of flexible display screen detection, and in particular to an intelligent flexible display screen performance test system and a test method. Background Art

[0002] Flexible display is a new type of display that uses a plastic substrate instead of the common glass substrate. It uses thin-film packaging technology and has a protective film attached to the back of the panel. Flexible display makes the display panel bendable and not easy to break. The use of flexible display is beneficial to the manufacturing of a new generation of high-end smartphones. At the same time, compared with traditional screens, flexible screens have obvious advantages. Not only are they lighter and thinner in size, but they also consume less power than the original devices, which helps to improve the battery life of the device. At the same time, based on their bendable and flexible characteristics, their durability is much higher than previous screens, reducing the probability of accidental damage to the device. Flexible display screens usually need to be tested for folding performance before leaving the factory.

[0003] At present, there are the following problems in the batch manufacturing and testing process of flexible displays: 1. In the traditional folding performance test of flexible display screens, due to the different sizes of flexible display screens, when testing the folding performance of flexible display screens, it is necessary to constantly replace the fixtures, which is a complicated process and increases the cost of the folding performance test of flexible display screens; 2. In the traditional flexible display folding performance test process, the maximum number of times the flexible display can be bent at different bending degrees is measured by manually recording the folding performance test. Since flexible displays made of different materials require different folding ranges, the state of the flexible display at the bending limit is not monitored during the folding process, and it cannot well reflect the test data of the flexible display, and the test results are relatively simple.

[0004] Therefore, there is an urgent need to provide an intelligent flexible display performance test system and test method to solve the above problems. Summary of the invention
