Array substrate and control method thereof, manufacturing method thereof and electronic paper display device

A control method based on an array substrate, wherein:

• the array substrate is applied on an electronic paper display device, and comprises a substrate, a plurality of thin film transistors provided on the substrate, and a plurality of pixel electrode structures provided on a side of the thin film transistors away from the substrate;
• each thin film transistor comprising an active layer, a source and a drain, a conductive channel being provided between the source and the drain and being provided on the active layer;
• each pixel electrode structure comprises a first pixel electrode and a second pixel electrode spaced from each other, the first pixel electrode corresponds to the conductive channel and is connected to a signal line, and the second pixel electrode is connected to the drain through a conductive through hole, and
• wherein the control method based on the array substrate comprises:
• obtaining a light intensity parameter of an environment where the array substrate is located;
• and
• determining a driving strategy of the pixel electrode structure based on the light intensity parameter.
