Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, the present invention provides a device 100 for testing the life of a flexible display screen 110 in a cyclic bending process. The flexible display screen cyclic bending life test device 100 comprises a fixed platform 10 and a movable platform 20 arranged in parallel with the fixed platform 10. The fixed platform 10 and the movable platform 20 are at different heights, and there is a height difference between the fixed platform 10 and the movable platform 20. The movable stage 20 is movable in a first direction X, and the fixed stage 10 is movable in a second direction Y. Wherein the first direction X is perpendicular to the second direction Y. By moving the movable stage 20 in the first direction X, the relative position between the movable stage 20 and the fixed stage 10 in the first direction X can be adjusted. By moving the stationary platen 10 in the second direction Y, the height difference between the stationary platen 10 and the movable platen 20 is adjusted. The plane of the fixed platform 10 and the plane of the movable platform 20 are both parallel to the first direction X and perpendicular to the second direction Y. In this embodiment, there is one fixed platform 10, and the fixed platform 10 and the movable platform 20 are disposed opposite to each other, but it should be understood that in other embodiments, the fixed platform 10 and the movable platform 20 may be disposed in a staggered manner.
Referring to fig. 1, the number of the fixed platforms 10 of the flexible display screen cyclic bending life test apparatus 100 may be multiple, and the multiple fixed platforms 10 are arranged at intervals along the third direction Z. The third direction is perpendicular to both the first direction X and the second direction Y. Wherein, a plurality of the fixed platforms 10 correspond to one of the movable platforms 20, so as to simultaneously realize the cyclic bending life test of a plurality of the flexible display screens 110.
Referring to fig. 2(a) and 2(b), when the flexible display screen 110 to be tested is tested by the flexible display screen cyclic bending life testing apparatus 100, one end of the flexible display screen 110 to be tested is fixed on the fixed platform 10, and the other end is fixed on the movable platform 20. Because the fixed platform 10 and the movable platform 20 are supported by a height difference, when two ends of the flexible display screen 110 are respectively fixed on the fixed platform 10 and the movable platform 20, the flexible display screen 110 can be naturally bent, a circular arc-shaped curved surface can be generated at the bent position, and the curvature radius of the curved surface is half of the height difference between the fixed platform 10 and the movable platform 20. Therefore, the curvature of the flexible display screen 110 can be adjusted to a desired curvature value by adjusting the height difference between the fixed platform 10 and the movable platform 20. Compared with the mode of realizing the bending of the flexible display screen 110 through a round roller in the prior art, the method does not need to arrange the round roller, so that the contact between the round roller and the flexible display screen 110 is avoided, and the friction damage of the round roller to the flexible display screen 110 is avoided. Meanwhile, the curvature of the arc-shaped curved surface can be adjusted randomly, and different testing requirements of different types of flexible display screens 110 are met. Further, the bending position of the flexible display screen 110 can be adjusted by moving the movable platform 20 in the first direction X. Specifically, two ends of the flexible display screen 110 are respectively fixed to the fixed platform 10 and the movable platform 20, and the movable platform 20 is moved along the first direction X to adjust the relative position between the fixed platform 10 and the movable platform 20 in the first direction X, so as to change the relative position between the two ends of the flexible display screen 110 in the first direction X, and further adjust the bending position of the flexible display screen 110. The movable platform 20 is driven to reciprocate along the first direction X, so that the cyclic bending test of each position of the flexible display screen 110 can be realized, and the cyclic bending service life of the flexible display screen 110 can be obtained through the test. In this embodiment, the fixed platform 10 and the movable platform 20 are disposed opposite to each other, so that when two ends of the flexible display screen 110 are respectively fixed to the fixed platform 10 and the movable platform 20, the flexible display screen 110 is bent in a bending direction, and the bending life of the flexible display screen 110 when bent in the bending direction can be tested. It is understood that, in other embodiments of the present invention, the fixed platform 10 and the movable platform 20 are arranged in a staggered manner, so that when two ends of the flexible display screen 110 are respectively fixed on the fixed platform 10 and the movable platform 20, the flexible display screen 110 is bent in other bending directions, and thus the bending life of the flexible display screen 110 when bent in other directions can be tested.
When the fixed platforms 10 are multiple, one end of each of the two flexible display screens 110 may be fixed to each of the fixed platforms 10, and the other end of each of the two flexible display screens 110 is fixed to the movable platform 20. By adjusting the height difference between the two fixed platforms 10 and the movable platform 20 to be the same or different, the cyclic bending life test of the same curvature or the cyclic life test of different curvatures of the two flexible display screens 110 can be simultaneously realized, and the test efficiency is improved.

In this embodiment, the number of the slide rails 41 is three, two of the slide rails correspond to two opposite sides of the movable platform 20, and the other slide rail is located between the two slide rails 41. Therefore, the three slide rails 41 and the corresponding slide blocks 42 can stably support the movable platform 20 and can drive the movable platform 20 to move stably. It is understood that the number of the slide rails 41 may be two or more, and the specific number thereof may be changed according to the size of the movable platform 20. The driving member 43 is connected to the movable platform 20 and is used for driving the movable platform 20 to slide along the slide rail 41. In this embodiment, the driving unit 43 includes a screw rod 431 parallel to the slide rail 41, a motor 432 connected to one end of the screw rod 431, and a slider 433 connecting the movable platform 20 and the screw rod 431.

In this embodiment, the adjusting member 53 includes a screw 531 parallel to the guide rail 51 and a sliding block 532 connecting the screw 531 and the fixed platform 10. The fixed platform 10 is connected with the screw 531 through the sliding block 532. When the screw 531 is driven to rotate, the slide block 532 moves along the screw 531, so that the fixed platform 10 moves along the second direction Y. In this embodiment, a height adjusting handwheel 532 is disposed at one end of the screw 531 away from the first fixing plate 31, so that the screw 531 is manually driven by the height adjusting handwheel 532 to rotate, so as to adjust the position of the fixed platform 10 in the second direction Y.
