Abstract: Disclosed is a method for manufacturing a flexible organic light-emitting diode (OLED) display component which includes steps of: forming a ferromagnetic material layer on a surface of a flexible substrate; and abutting the ferromagnetic material layer against a flat bearing surface, and applying a magnetic pull force directing to the bearing surface on the ferromagnetic material layer. Drawn by the magnetic pull force, the ferromagnetic material layer abuts closely against the flat bearing surface, smoothing out the flexible substrate, and meanwhile fixing the flexible substrate on the bearing surface.
