Abstract

The invention provides a display panel with a fingerprint identification function, a preparation method and a display device for achieving an OLED display with the fingerprint identification function, reducing the process complexity and saving the cost. The display panel with the fingerprint identification function provided by the invention comprises an array substrate, an anode layer, a pixel definition region, a plurality of organic light-emitting units, an isolating column, a reuse electrode layer, a second electrode layer and a cover plate, wherein the anode layer is located on the array substrate; the plurality of organic light-emitting units are surrounded by the pixel definition region; the pixel definition region and the organic light-emitting units are located on the anode layer; the isolating column is located on the pixel definition region; the reuse electrode layer is located on the isolating column and the organic light-emitting units; the reuse electrode layer comprises a cathode layer and a first electrode layer; the reuse electrode layer covering the isolating column is taken as a first electrode layer; the reuse electrode layer surrounded by the first electrode layer is taken as the cathode layer; the first electrode layer and the cathode layer are arranged on the same layer and are not connected with each other; the second electrode layer is located on the reuse electrode layer; and the cover plate is located on the second electrode layer.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel with a fingerprint identification function, a preparation method, and a display device. Background technique [0002] An organic light-emitting diode (Organic Light-Emitting Diode, OLED) display is also called an organic electroluminescence display (Organic Electroluminescence Display, OELD). Among various types of flat panel displays, OLED displays have the advantages of wide viewing angle, high brightness, high contrast ratio, low driving voltage and fast response. see figure 1 , the existing OLED display panel includes from bottom to top: an array substrate 101, an anode layer 102, an organic light-emitting layer 103, and a cathode layer 104; wherein, the organic light-emitting layer includes a pixel defining region and a plurality of organic light unit ( figure 1 not marked). [0003] Fingerprint is an invariable feature that is unique and disti...
