Abstract
The disclosure discloses an OLED display panel, a driving method thereof and a display device. In a texture recognition period, a first light emitting element in a texture recognition area is controlled to be in an off state, wherein the first light emitting element includes at least a light emitting element of which a spacing from an edge of a pinhole imaging area is closest in the texture recognition area; and then an image of an object, formed through the pinhole imaging area, is obtained by an image sensor, the object being in the texture recognition area and above the display panel, so as to implement the texture collection and recognition functions.
