Abstract
A display panel includes: a plurality of light-emitting pixels arranged in an array, a first shift register unit and a second shift register unit, wherein the first shift register unit is connected to data writing transistors in an irow and an (i+1)row and configured to provide a first controlling signal for the two adjacent rows of pixel circuits, and the data writing transistor is turned on in response to the first controlling signal; the second shift register unit is connected to threshold compensating transistors in the irow and an (i−1)row, and configured to provide a second controlling signal for the two adjacent rows of pixel circuits, and the threshold compensating transistor is turned on in response to the second controlling signal; and wherein a first turn-on period of the data writing transistor is partially overlapped with a second turn-on period of the threshold compensating transistor.
