Problems solved by technology

When the pixel displays many frames of black images, the driving transistor is in the off state for a long time. At this time, due to the high potential of the control terminal of the driving transistor, the driving transistor is in the positive bias for a long time, and the threshold voltage drifts, and then switches to For a white screen, the threshold voltage of the drive transistor cannot be restored in time, that is, the hysteresis effect of the drive transistor causes the display brightness to be low in the first few frames of white screen, and the display effect is poor

Abstract

The invention discloses a display panel and a scanning driving method thereof. The display panel comprises a display area; the display area comprises a plurality of sub-pixels arranged in an array, and the sub-pixels are arranged in the first direction to form a pixel row. The array substrate further comprises n signal line sets arranged in the second direction, each signal line set comprises a scanning signal line extending in the first direction and a reset control signal line extending in the first direction, and the signal line sets correspond to the pixel rows in a one-to-one mode. Wherein the scanning signal line in the i-th signal line group is electrically connected with the reset control signal line in the (i + j)-th signal line group, both n and i are positive integers, j is a positive integer greater than or equal to 3, and i + j is less than or equal to n; the first to j-th reset control signal lines are not electrically connected with the scanning signal line; the first direction intersects the second direction. According to the display panel and the scanning driving method thereof provided by the invention, the power consumption caused by resetting can be reduced while the hysteresis characteristic of the driving transistor is improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display panel and a scanning driving method thereof. Background technique [0002] Organic Light-Emitting Diode (OLED) is one of the hot spots in the field of flat panel display research today. Compared with Liquid Crystal Display (LCD), OLED display has low energy consumption, self-illumination, wide viewing angle and response speed Fast and other advantages. [0003] A plurality of pixel circuits are arranged in the OLED display, and the pixel circuits generally include a driving transistor, a plurality of switching transistors, storage capacitors and organic light emitting diodes, and the driving current generated by the driving transistors drives the organic light emitting diodes to emit light for display. When the pixel displays many frames of black images, the driving transistor is in the off state for a long time. At this time, due to the high potentia...
