Display devices and methods for driving display devices are provided. The method may include, in a first stage of the data writing phase, always turning on m1 first switch units of each multiplexer under a control of m1 corresponding clock signal lines, and sequentially turning on m2 second switch units for a preset time in a preset order; in a second stage of the data writing phase, keeping the m1 first switch units always on, turning off the m2 second switch units, and writing corresponding data voltage signals to the row of sub-pixels to cause the row of sub-pixels to display; and in the display maintaining phase, displaying same as in the second stage of the data writing phase. At least one first switch unit is always turned on under the control of a corresponding clock signal line when at least two continuously scanned rows of sub-pixels are displaying.

Display device and driving method thereof

The display panel includes an array substrate, and the array substrate includes pixel circuits arranged in an array. A first initialization module and a second initialization module are connected in series to an initialization signal terminal and a control terminal of the drive module, an output terminal of the second initialization module is electrically connected to the control terminal of the drive module; a control terminal of the first initialization module is used for receiving a first additional scan signal, and a control terminal of the second initialization module is used for receiving a first scan signal. Within at least one light emitting period of one frame duration, the end time of an active level pulse of the first additional scan signal is later than the end time of an active level pulse of the first scan signal.
