Abstract
The disclosure discloses an organic electroluminescent display panel, a driving method thereof and a display device, where the dimming mode is taken to drive and each frame of scanning time is divided into the display area scanning time and the front-back porch time. Where each line of pixel circuits located in the display area of the organic electroluminescent display panel are scanned during the display area scanning time; and the drive circuit is adjusted during the front-back porch time. Where the front-back porch time is less than the display area scanning time, and the front-back porch time is the common multiple of the respective clock signal cycles in the gate drive circuit of the organic electroluminescent display panel.
