Abstract
A method of driving a display device, where the display device includes a display substrate including a plurality of rows of pixel circuits, and in each pixel circuit, a reset compensation circuit and a data writing circuit are connected at a second node, and the reset compensation circuit is connected to a reset control signal line and a first voltage input terminal; in a driving stage, driving a light emitting device OLED connected to each of other rows of pixel circuits except a last row of pixel circuits further includes a charge maintenance stage performed after a light emission voltage generation stage; and in the stable display stage, all light emitting devices OLED simultaneously emit light; where in the charge maintenance stage, the first voltage input terminal is disconnected from the second node by the reset compensation circuit in response to control of a reset control signal.
