Claim:
1. An OLED array substrate including a switching thin film transistor and a driving thin film transistor, wherein, an S factor of the switching thin film transistor is less than that of the driving thin film transistor; wherein, the switching thin film transistor and the driving thin film transistor respectively include an active region, a gate, and a gate insulating layer insulatedly separating the active region and the gate from each other, the gate insulating layer of the driving thin film transistor has a first thickness, and the gate insulating layer of the switching thin film transistor has a second thickness; wherein, the second thickness of the gate insulating layer of the switching thin film transistor ranges from 600 nm to 800 nm; and the first thickness of the gate insulating layer of the driving thin film transistor ranges from 800 nm to 2000 nm.
