An OLED display panel comprises: an OLED unit, comprising one or more pixel light-emitting units, wherein light emitted by the pixel light-emitting units is transmitted within a first area; a rotatable optical element, arranged on a transmission light path of the light emitted by the pixel light-emitting units, wherein the light emitted by the pixel light-emitting units is reflected after being transmitted and incident onto the optical element, and the light after being reflected by the optical element is distributed in a second area within a predetermined time by means of the rotation of the optical element, wherein the second area is larger than the first area; and a light-transmitting display substrate, arranged on a transmission light path of the light reflected by the optical element, and arranged correspondingly to the second area. |
