The invention relates to a flexible display panel stretching and retracting measuring device and a display device.In the flexible display panel stretching and retracting measuring device, a flexible display panel is wound around the outer surface of a first rotating shaft, when the flexible display panel is stretched or loosened, the first rotating shaft correspondingly rotates clockwise or anticlockwise, and in the rotating process of the first rotating shaft, the first rotating shaft rotates clockwise or anticlockwise; the sensor can detect the rotation amount of the first rotating shaft in the rotating process and generate a detection signal, the processor determines whether the flexible display panel is in a stretched state or a relaxed state based on the change of the detection signal, and in addition, the flexible display panel stretches and retracts once every time the detection signal changes. Therefore, the telescopic measuring device can realize the detection of the telescopic state and the telescopic times. Generally, the stretching times of the flexible display panel are within a certain interval, and the service life of the flexible display panel can be estimated by monitoring the stretching times of the flexible display panel.
Description
technical field [0001] The present disclosure relates to the field of display technology, and in particular, to a telescopic measurement device of a flexible display panel and a display device. Background technique [0002] At present, with the development of flexible display technology, more possibilities are provided for the form of flexible display terminals, such as display terminals equipped with foldable screens and slidable screens that have appeared in recent years. [0003] However, most of the existing foldable display terminals or sliding display terminals do not have the function of detecting the expansion and contraction state and the number of times of expansion and contraction. [0004] It should be noted that the information disclosed in the above Background section is only for enhancement of understanding of the background of the present disclosure, and therefore may contain information that does not form the prior art that is already known to a person of or...
