Abstract
A pixel driving circuit and a display panel are provided. The pixel driving circuit includes a light-emitting module, an external detection module, and an internal compensation module. The light-emitting module is electrically connected to the external detection module and the internal compensation module. The external detection module is configured to acquire a threshold voltage of a second transistor when a display panel is turned on, and determine a shift direction of the threshold voltage. When the shift direction of the threshold voltage is a positive shift, the pixel driving circuit uses a first timing sequence to compensate the threshold voltage. When the shift direction of the threshold voltage is a negative shift, the pixel driving circuit uses a second timing sequence to compensate the threshold voltage.
