  • Patent number: 10879320
    Abstract: An organic light-emitting display panel has a display region including a fingerprint recognition region and light-emitting devices for displaying image, the display panel includes a driving device layer, an anode layer, a pixel definition layer, an organic light-emitting layer, and a cathode layer sequentially stacked; and an optical fingerprint recognition sensor located in the fingerprint recognition region and located at a side of the driving device layer away from the anode layer; the pixel definition layer includes sub-pixel openings corresponding to the light-emitting devices, each light-emitting device includes an anode corresponding to one sub-pixel opening, the anode being located in the anode layer and overlapping with a corresponding sub-pixel opening, the organic light-emitting layer is located in each sub-pixel opening, and the cathode layer overlaps with each sub-pixel opening; in the fingerprint recognition region, at least part of the light-emitting devices each have an anode being a transpare
