Abstract: Disclosed in the present disclosure are an OLED display panel, a driving method therefor and a display device. A first light-blocking layer is disposed between a photosensitive unit and an organic electroluminescent structure, and the first light-blocking layer at least has a hollow area corresponding to a fingerprint identification area. When a finger touches a screen, the lights emitted by the organic electroluminescent structure are reflected by the finger to irradiate the photosensitive unit through small holes, such that fingerprint information of the finger is detected due to the brightness differences among the lights reflected by ridges and valleys of the finger. The small holes in the hollow area can function to improve the light intensity convergence, thus increasing the sensitivity to finger touches to the greatest extent.
