Abstract

The invention provides an array substrate and a driving method thereof, a display panel and a display device. The array substrate comprises a plurality of circulating units and a plurality of pixel circuits. Each circulating unit consists of four sub-pixel units located in four columns and two rows, sub-pixel units in any two adjacent columns are located in different rows and have different colors, and sub-pixel units in at least one row have different colors. Each sub-pixel unit is connected to one pixel circuit, and each sub-pixel unit comprises a first sub-pixel and a second sub-pixel located in the same column and having the same color. The pixel circuit is configured to drive the first sub-pixel when a first frame picture is displayed, and to drive the second sub-pixel when a second frame picture is displayed.
