Abstract

One end of a flexible display screen (110) to be tested is fixed on a fixed platform (10), and the other end of the flexible display screen is fixed on a movable platform (20) which is located on a plane with a different height from the fixed platform (10), so that the flexible display screen (110) is naturally bent to form a curved surface. Moreover, the curvature of the curved surface can be changed by adjusting the fixed platform (10) in the second direction so as to achieve the specified curvature required by the test and meet different test requirements of different types of flexible display screens (110). Furthermore, the moving platform (20) is moved back and forth along the first direction, so that the distance between two ends of the flexible display screen (110) can be changed continuously, the position of the bending surface can be changed continuously, and the cyclic bending service life of the flexible display screen (110) can be tested.
