Abstract: Provided are a touch display panel and a display device. The touch display panel includes a first touch electrode, a second touch electrode, a shielding signal line, and a driving chip. The first touch electrode and the driving chip are electrically connected by a first electrode line. The first electrode line includes at least one part located in a first non-display region of the touch display panel. The second touch electrode includes a first touch sub-electrode and a second touch sub-electrode, which are connected by a first connection line. The first connection line includes at least one part located in the first non-display region. The shielding signal line includes at least one part located in the first non-display region. In the first non-display region, the first electrode line and the first connection line are isolated by the shielding signal line.

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.
