Abstract
An organic light emitting diode (OLED) display panel and a display device are provided. A first pixel driving circuit of the is configured to compensate a threshold voltage of a drive transistor in the bending area during a first time period before starting up or a second time period after shutting down. A second pixel driving circuit is configured to compensate a threshold voltage of a drive transistor in the non-bending area during a blank time period between adjacent display frames. A duration of the first time period and a duration of the second time period are both greater than a duration of the blank time period. A brightness of the display panel is uniform.
