Abstract

The embodiment of the invention discloses an array substrate and a driving method thereof, a display panel and a display device. The array substrate comprises pixel circuits arranged in an array mode,wherein a first initialization module and a second initialization module are connected in series between an initialization signal end and the control end of the driving module; the output end of thesecond initialization module is electrically connected to the control end of the driving module, the output end of the first initialization module and the input end of the second initialization moduleare electrically connected to the first intermediate node, and the first pole of a light emitting module is electrically connected to a reset node; the control end of the first initialization moduleis used for receiving a first additional scanning signal, and the control end of the second initialization module is used for receiving a first scanning signal; and in at least one light-emitting period of a frame duration, the effective level end time of the first additional scanning signal lags behind the effective level end time of the first scanning signal. Therefore, the flicker phenomenon ofthe power-saving mode can be improved, and the image display effect of the display panel and the display device can be improved.

Description

technical field

[0001] The present invention relates to the field of display technology, in particular to an array substrate and a driving method thereof, a display panel and a display device. Background technique

[0002] With the development of display technology, active matrix organic light emitting diode (Active Matrix Organic Light Emitting Diode, AMOLED) display panel gradually entered the market, compared with traditional thin film transistor liquid crystal display panel (Thin Film Transistor Liquid Crystal Display, TFT LCD), The AMOLED display panel has the advantages of low energy consumption, self-illumination, wide viewing angle, fast response speed, and easy application to flexible display technology. The AMOLED display panel can generally be driven by current, that is, the light-emitting module is controlled to emit light by using the driving current.

[0003] In order to realize the control of the driving current flowing through the light-emitting module, it i...
