Abstract
The present disclosure provides a pixel driving circuit and a display panel. After pre-charging a first node to a first electrical potential, raising it to a second electrical potential through a first capacitor by a current row gate output signal G(n), and then raising it to a third electrical potential which is a high electrical potential greater than an electrical potential of the current row gate output signal G(n), so that a first transistor is turned on and data is written, raising an original electrical potential of a gate and improving driving capability since a gate electrical potential of the first transistor can be raised to greater than the G(n).
