In a possible implementation manner, fig. 3 is a schematic structural diagram of another array substrate provided in an embodiment of the present application. As shown in fig. 3, the array substrate provided in the embodiment of the present application further includes at least two data lines 400, where the data lines 400 are indicated by two-dot chain lines in fig. 3, it should be noted that each row of pixel units 101 shown in fig. 3 can be electrically connected by using the data lines 400, and the data lines 400 between each row of pixel units in fig. 3 are not illustrated due to the number of lines; each of the driving units 210 mentioned in the above embodiments further includes a data driver 212, and the data driver 212 is electrically connected to the target pixel unit through the data line 400. The target pixel unit is the pixel unit 101 in the display sub-area 110 correspondingly driven by the driving unit 210. The scan driver 211 may provide scan signals to the pixel unit 101 to perform scan driving, i.e., drive the Thin Film Transistors (TFTs) in the pixel unit 101 to be turned on or off, so that the scan lines 300 are electrically connected to the gates of the TFTs. The data driver 212 may provide data signals to the pixel unit 101, i.e., input data signals to TFTs within the pixel unit 101, and the data line 400 is electrically connected to a source of a thin film transistor. The display signal generally includes a scan signal and a data signal to realize a picture display.
