    摘要: The present disclosure provides a display panel, a manufacturing method thereof, and a display device. The display panel includes a plurality of optical fingerprint identification structures, each optical fingerprint identification structure includes a display region and a sensing region, the display region includes a driving circuitry layer, a planarization layer, a. pixel definition layer, and a light-emitting element, and the light-emitting element includes an anode, a light-emitting material layer and a cathode. The sensing region includes a sensing region opening, an optical sensor and a cathode metal layer, the cathode metal layer includes a first cathode metal layer and a second cathode metal layer, and the first cathode metal layer is separated from the second cathode metal layer by a gap, so that light emitted by the light-emitting element is allowed to enter the optical sensor through the gap after being reflected by a fingerprint.

    摘要: A touch display panel, a manufacturing method thereof and a method of detecting a touch for the same are disclosed. The touch display panel includes a first substrate (01) and a second substrate (02). The first substrate (01) includes, within its non-display region, a plurality of gate lines (10) parallel to each other, a plurality of data lines (20) parallel to each other, a plurality of first touch electrode lines (30) parallel to the gate lines (10), and a plurality of second touch electrode lines (40) parallel to the data lines (20). The first substrate (01) further includes first touch electrodes (50) electrically connected to the first touch electrode lines (30) and second touch electrodes (60) electrically connected to the second touch electrode lines (40). Between two adjacent data lines (20), there are two sub-pixels arranged in the same row on the first substrate (01). A second touch electrode line (40) is located between the two sub-pixels. A pair of gate lines (10) are located between any two adjacent rows of sub-pixels on the first substrate (01), and a first touch electrode lines (30) is located between the pair of the gate lines (10). Since the first touch electrode line (30) and the second touch electrode line (40) are disposed within the light-proof non-display region, their impact on the aperture ratio can be avoided.
