Abstract
Disclosed are a row drive circuit () of an array substrate and a display device. The row drive circuit () includes N row drive units () arranged in cascade and auxiliary circuit units (). The Nrow drive unit () is configured to output Ngate driving signal to pre-charge and charge the Nrow of sub-pixels, when its signal input end receives the gate driving signal output by (N−2)row drive unit (). The Nauxiliary circuit unit () is configured to control Nrow drive unit () skip pre-charging the sub-pixels, when (N−1)timing control signal received by the first timing signal input end of Nauxiliary circuit unit () and (N+1)timing control signal received by the second timing signal input end of Nauxiliary circuit unit () are high level. N is positive integer greater than or equal to two. The present disclosure solves the problem that the charging saturation of two adjacent pixels which both share one data line is inconsistent due to the large step voltage of the data voltage, when the data signal is converted. As such bright lines and dark lines may be generated in the display panel. Therefore, the display device has a good displaying effect.
