摘要（英）：

The invention relates to the field of display technology, specifically to a current acquisition device, a drive unit and a method, an array substrate and its preparation method. The charging current acquisition device is used for acquiring charging current of a thin film transistor in a display area of a display device and comprises a detection thin film transistor which has the same structure as the thin film transistor in the display area. According to the charging current acquisition device, the detection thin film transistor having the same structure as the thin film transistor in the display area is arranged, and the detection thin film transistor is provided with a scanning signal which is the same as a scanning signal of the thin film transistor in the display area as well as a data signal which has the same voltage as a data signal selected by the thin film transistor in the display area. Charging current of a display panel is accurately reflected by the utilization of the detection thin film transistor, thus providing basis for regulation of a driving signal. In addition, the charging current acquisition device has a simple structure and is easy to implement.
