1. An apparatus for fabricating a flexible display screen, comprising a roller mechanism and a jig, wherein the jig comprises a bearing surface configured to bear a flexible display panel, the bearing surface being a curved surface; and the roller mechanism comprises a roller, an axis of the roller being parallel to an element line of the bearing surface, and the roller being configured to roll on the bearing surface along a directrix of the bearing surface,
wherein the bearing surface comprises a flexible-circuit-board positioning groove; wherein the flexible-circuit-board positioning groove is disposed on an end of the bearing surface along a direction of the directrix, and along a direction of the element line of the bearing surface, a width of the flexible-circuit-board positioning groove is less than a length of the roller, such that the roller is prevented from entering the flexible-circuit-board positioning groove.
