1. A driving method of an Organic Light Emitting Diode (OLED) display panel, comprising:

  • in a texture recognition period, controlling a first light emitting element in a texture recognition area to be in an off state, wherein the first light emitting element comprises 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

    obtaining, by an image sensor, an image of an object formed through the pinhole imaging area, the object being in the texture recognition area and above the display panel;

    wherein the first light emitting element comprises all light emitting elements of which spacings from the edge of the pinhole imaging area are smaller than a preset spacing in the texture recognition area;

    the preset spacing is determined according to a distance between a strong reflection interface in the OLED display panel and an upper surface of a light shading layer having the pinhole imaging area, a distance between the strong reflection interface in the OLED display panel and an upper surface of the light emitting element, and a maximum angle at which the image sensor in the OLED display panel receives light.
