Abstract: The present application discloses a pixel driving circuit and a display panel. Before the charging module charges the pixel electrode, the present application releases the voltage of the pixel electrode by means of the discharging electrode. Therefore, it is possible to avoid that the voltage of the pixel electrode is charged to a target value after the residual voltage on the pixel electrode needs to be canceled during charging the pixel electrode by the charging module. As a result, the power consumption of the pixel electrode during the charging/discharging process can be reduced, and the charging/discharging time period of the pixel electrode can be reduced.

Abstract: The present disclosure provides a display panel and a display device. A distance from a surface of a first conductive adhesive layer close to a first pin, electrically connecting the first conductive pad and the first pin, to the substrate is different from a distance of a surface of a second conductive adhesive layer electrically connected to the second conductive pad and the second pin to the substrate, to compensate for a height difference caused by the partial warpage of the pins on the drive chip when binding a drive chip, so as to ensure that the drive chip can be well bonded to the display panel.
