Abstract

The embodiment of the invention provides an organic light-emitting display panel and a display device, relates to the technical field of display, can realize a fingerprint identification function in adisplay area, and is beneficial to the design of a narrow frame. The organic light-emitting display panel comprises a display area which comprises a fingerprint recognition area; the organic light-emitting display panel comprises a driving device layer, an anode layer, a pixel definition layer, an organic light-emitting layer and a cathode layer which are sequentially stacked. The organic light-emitting display panel also comprises an optical fingerprint identification sensor positioned in the fingerprint identification area, and the optical fingerprint identification sensor is positioned onone side of the driving device layer far away from the anode layer; and at least part of the anode of the light-emitting device is a transparent electrode in the fingerprint identification area.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an organic light-emitting display panel and a display device. Background technique [0002] With the development of display technology, Organic Light Emitting Display (OLED) panels are more and more widely used due to their excellent characteristics such as self-illumination, high brightness, wide viewing angle, and fast response. In order to realize the fingerprint identification function, it has appeared that a fingerprint identification sensor is set in the frame area of ​​the organic light-emitting display panel to form a fingerprint identification area, and the fingerprint identification function is realized in the fingerprint identification area. However, due to the need for sufficient fingerprint identification area to identify fingerprints, The area of ​​the border area is larger. Contents of the invention [0003] Embodiments of the present invention provide ...
