Abstract
Disclosed are a pixel driver circuit, a display panel, a display device, and a driving method. The pixel driver circuit includes a data write module, a storage module, a first potential adjustment module, a second potential adjustment module, a comparison module, and a light emission control module. The data write module is configured to write a data signal into a first node at a first stage. The first potential adjustment module and the second potential adjustment module are configured to adjust a potential of a second node at a second stage and at a third stage, causing the comparison module to output a first control signal and a second control signal to the light emission control module at the second stage and at the third stage, respectively. The light emission control module is configured to control the light emission control module to be turned off and turned on according to the first control signal and the second control signal, respectively.
