Claim:
1. A method of preparing a display screen, comprising: forming a flexible base layer on a rigid base substrate, wherein the rigid base substrate comprises a first region, a second region, and a connection region between the first region and the second region, and the flexible base layer is formed in at least both the second region and the connection region; fabricating an organic light emitting diode device on the substrate with the flexible base layer formed thereon; stripping the rigid base substrate in the second region along a boundary between the second region and the connection region; wherein, before the step of fabricating an organic light emitting diode device on the substrate with the flexible base layer formed thereon, the method further comprises: preparing a gate driver on array circuit on the substrate with the flexible base layer formed thereon, the gate driver on array circuit being configured for controlling an entire display screen.
