At an initial compensation stage, a display screen can be subjected to brightness calibration by an image sensor so as to acquire a data voltage compensation value of each sub-pixel when a brightness value of a display panel equals a preset value, a first data voltage is output to a corresponding pixel circuit according to the data voltage compensation value of each sub-pixel, a sensed voltage of each sub-pixel at this stage is used as an initial reference voltage of each sub-pixel when the brightness value of the display panel equals the preset value; and at a subsequent compensation stage, by regulating a data voltage of each sub-pixel, the sensed voltage of each sub-pixel is made to be equal to the corresponding initial reference voltage when the brightness value of the display panel equals the preset value, so as to achieve uniform compensation on brightness of each sub-pixel at the subsequent compensation stage. Thus, not only are uniformity and accuracy of initial brightness compensation improved, but also pixel aging is accurately compensated and uniformity and accuracy of subsequent compensation are improved.

Abstract: The present invention provides an array substrate and a manufacturing method thereof. The array substrate of the present invention comprises multiple pixel units arranged in an array, each pixel unit comprising a substrate, an active layer, a source layer and a drain layer arranged in the same layer, and a gate layer; wherein each pixel unit further comprises a power wire layer connected to the source layer via a via hole. Since the power wire layer of the present invention is separately provided as a layer, the area of the projection of the power wire layer on the substrate may be larger, that is, the conductive cross-sectional area of the power wire layer may be larger, and thus the resistance of the power wire layer is decreased. Therefore, difference among currents of different pixel units is reduced, and thus the mura phenomenon generated in displaying is alleviated.
