Abstract
A flexible display screen, a bending detection method and device, a driving method are disclosed. The flexible display screen includes an array substrate, a light emitting device on a side of the array substrate, and an elastic conductor layer on a side of the array substrate distal to the light emitting device. The array substrate includes at least one target region, and a plurality of storage capacitors in each target region. The array substrate further includes a target electrode-plate including first electrode-plates of storage capacitors in the same target region. The target electrode-plate is electrically connected to a detecting signal terminal, and the detecting electrode-plate includes at least the target electrode-plate. The array substrate is configured to form a bending detection capacitor collectively by the detecting electrode-plate and the elastic conductor layer in response to the target electrode-plate receives detecting signal.
