A pixel circuit, a driving method of the pixel circuit, and a display panel

Abstract

The invention discloses a pixel circuit, a driving method of the pixel circuit and a display panel. The pixel circuit comprises a data voltage write-in module, a driving transistor, a light emitting module, a storage module, a first transistor and an electric leakage compensation module. The data voltage write-in module is used for writing data voltage into the driving transistor. The first transistor is electrically connected with the grid electrode of the driving transistor, and the first transistor is a compensation transistor or a reset transistor. The storage module is electrically connected with the driving transistor and used for storing grid voltage of the driving transistor. The electric leakage compensation module is electrically connected with the grid electrode of the driving transistor for compensating the potential of the grid electrode of the driving transistor. The driving transistor is used for outputting a driving signal to drive the light-emitting module to emit light according to the gate voltage. When the voltage is written into the grid electrode of the driving transistor, the electric leakage compensation module performs electric leakage compensation on the grid electrode of the driving transistor, so that the residual time of a frame of ghost shadow on the display panel can be reduced, and the ghost shadow phenomenon of the display panel is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a pixel circuit, a driving method for the pixel circuit, and a display panel. Background technique [0002] During the display process of the Organic Light-Emitting Diode (OLED) display panel, since the gate voltage of the drive transistor of the different pixel circuits is written to the data voltage at different times, when the display panel performs screen switching, the A picture does not disappear immediately, but slowly disappears with the next picture, causing short-term afterimage phenomenon on the OLED display panel. However, the leakage current phenomenon of the gate of the driving transistor in the pixel circuit makes the short-term afterimage phenomenon more obvious, which seriously affects the display effect.
