Abstract
The present invention discloses an OLED array substrate and a manufacturing method thereof, a display apparatus. The OLED array substrate includes a TFT and an OLED. The method includes: forming an oxide semiconductor layer by a film forming process, and performing one patterning process on the oxide semiconductor layer to form an active layer of the TFT and a first electrode of the OLED; sequentially forming a first insulating layer and a second insulating layer on the active layer and the first electrode of the OLED, the first insulating layer being a lyophilic layer, and the second insulating layer being a lyophobic layer; forming an accommodation cavity exposing the first electrode by performing a patterning process on the first and second insulating layers; and injecting, into the accommodation cavity, and drying a solution containing an organic light emitting material to form an organic light emitting material layer.
