Abstract: The present disclosure relates to the field of display technology, and proposes a pixel driving circuit, a pixel structure, and a display panel. The pixel driving circuit includes a plurality of driving transistors. For each driving transistor the first terminal is connected to a first power terminal, the second terminal is connected to a first node, and the control terminal is connected to a second node, so as to input current to the first node under the effect of the voltage at the second node. The low pixel density area of the display panel can be provided with the above-mentioned pixel driving circuit, so that the brightness difference between the low pixel density area and the high pixel density area can be avoided.
