Abstract: The disclosure discloses an improving method of bending display abnormality of a flexible display, including the following steps: detecting a characteristic parameter of a driving thin film transistor of each of pixels in the flexible panel during display bending; calculating a bending position of the flexible panel according to the characteristic parameter of the driving thin film transistor of each of pixels; performing image visual correction on an image displayed by the pixels located at the bending position of the flexible panel. The disclosure also discloses an improving device of display bending abnormality of a flexible display and a flexible display. In the disclosure, when the flexible display is displayed in a bent state, the pixels located at the bending position are corrected to improve the display abnormality, thereby enhancing the display quality.
