Abstract: Disclosed are an array substrate, a control method thereof, a manufacturing method thereof and an electronic paper display device. The array substrate includes a substrate and a plurality of thin film transistors provided on the substrate and a plurality of pixel electrode structures, each thin film transistor includes an active layer, a source and a drain, a conductive channel is provided between the source and the drain and is provided on the active layer, a plurality of pixel electrode structures each is provided on a side of each thin film transistor away from the substrate, each pixel electrode structure includes a first pixel electrode and a second pixel electrode spaced from each other, the first pixel electrode corresponds to the conductive channel and connected to a voltage line, and the second pixel electrode is connected to the drain through a conductive through hole.

Abstract: A big data regression verification method includes: adding first data source information, second data source information, and data feature information to a preset configuration file; when a script running instruction is detected, running a python automation script to establish a first data access channel to a database of a business system and a second data access channel to a database of a big data system based on the first data source information and the second data source information; processing and calculating data in the database of the business system and the database of the big data system according to the data feature information; and determining whether a calculated first result file corresponding to the database of the business system is consistent with a calculated second result file corresponding to the database of the big data system, to verify the data. A big data regression verification apparatus is further provided.
