Problems solved by technology

[0003] At present, in order to improve the stealing phenomenon of sub-pixels, it is necessary to use a lower reset signal to reset the anode of the organic light-emitting element. However, since the first reset transistor and the second reset transistor receive the same reset signal, this causes the drive transistor The reset signal received by the gate is also pulled down accordingly, which leads to some adverse effects on display performance
For example, when the reset signal received by the gate of the driving transistor is too low, in the data writing period, the gate of the driving transistor needs to write data voltage on the basis of a very low voltage, plus the pulse of the current scanning signal Shorter width means shorter charging time, which will lead to insufficient charging and make the display brightness deviate

Abstract

Embodiments of the present invention provide a display panel, a driving method thereof, and a display device, relating to the field of display technology, capable of making charging more sufficient, weakening the difference between the brightness of the first frame and other frames, and effectively improving the afterimage phenomenon. The above display panel includes: n pixel groups, each pixel group includes 2m pixel rows arranged along the first direction, n and m are positive integers greater than or equal to 1; each pixel row includes multiple pixel rows arranged along the second direction A pixel circuit; the pixel circuit includes: a driving transistor; a first reset module, configured to transmit the first reset signal provided by the first reset signal line to the gate of the driving transistor in response to the first scanning signal provided by the first scanning signal line , the first reset signal includes alternating high level and low level; the second reset module is used to respond to the second scan signal provided by the second scan signal line, and transmit the second reset signal provided by the second reset signal line to the organic The anode of the light-emitting element.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a display panel, a driving method thereof, and a display device. 【Background technique】 [0002] In the prior art, the pixel circuit includes a drive transistor, a first reset transistor, and a second reset transistor, the first reset transistor and the second reset transistor are electrically connected to the same reset signal line, and the reset signals supplied by the reset signal terminal line are respectively The gate of the driving transistor and the anode of the organic light emitting element are reset. [0003] At present, in order to improve the stealing phenomenon of sub-pixels, it is necessary to use a lower reset signal to reset the anode of the organic light-emitting element. However, since the first reset transistor and the second reset transistor receive the same reset signal, this causes the drive transistor The reset signal received by the grid is als...
