Abstract:
1. A joining method for an organic light emitting diode (OLED) display device, the method comprising: providing a support and a flexible substrate; forming a first metal layer on one side of the support and a second metal layer on a first side of the flexible substrate; performing a cleaning process on the first metal layer and the second metal layer; forming a first radical layer on the first metal layer and a second radical layer on the second metal layer by a plasma process; joining the first radical layer to the second radical layer so that the flexible substrate, second metal layer, second radical layer, first radical layer, first metal layer and support are stacked in this order; forming an OLED display device on a second side of the flexible substrate, wherein the second side is opposing the first side; and detaching the first side of the flexible substrate from the second metal layer.
