Abstract: The present disclosure provides an electromagnetic shielding film, a flexible circuit board and a display device. The electromagnetic shielding film includes a central portion and an edge portion. The central portion has a plurality of surrounding side edges; and the edge portion is provided on at least one side edge of the central portion, and includes a plurality of protruding units protruding away from the central portion. The plurality of protruding units are arranged in an extending direction of the side edge where the edge portion is located. The electromagnetic shielding film is used to attach on a flexible circuit board body, the central portion is located on a non-bending area, and the edge portion is located on a bending area, so that the flexible circuit board is formed.

Abstract: The present disclosure provides a pixel circuit and a driving method thereof, a display device. The pixel circuit includes a reset sub-circuit, a compensation sub-circuit, a data writing sub-circuit, a storage capacitor, a driving transistor, a light emitting control sub-circuit and a light emitting sub-circuit. The compensation sub-circuit may write a threshold voltage of the driving transistor into a gate of the driving transistor in a date writing stage, so that magnitude of a drive current output by the driving transistor is independent of the threshold voltage of the driving transistor in a light emitting stage.
