Abstract: An organic light-emitting display panel and a manufacturing method thereof as well as an electronic device are provided. The organic light-emitting display panel includes: an array substrate; a photosensitive identification array including a plurality of photosensitive identification devices; and a photosensitive detection circuit including a common voltage input layer and a photosensitive detection switch. The photosensitive detection switch includes a drain metal layer, a first electrode of the photosensitive identification device is electrically connected with a drain metal layer of an associated photosensitive detection circuit and a second electrode thereof is electrically connected with the common voltage input layer of the associated photosensitive detection circuit. The common voltage input layer is overlapped with the first electrode of the associated photosensitive identification device or overlapped with the drain metal layer in the photosensitive detection circuit in a direction vertical to the array substrate, to form a photosensitive storage capacitor.
