Abstract

The invention discloses an electroluminescent display panel and a display device, comprising: a display area and a fingerprint identification area; the display area includes: a display pixel unit; the display pixel unit includes: a first pixel control circuit and a first light emitting unit; The light-emitting unit includes a first anode; the fingerprint identification area includes: a plurality of capacitive fingerprint identification electrodes arranged in an array, and electrode lines that are arranged in one-to-one correspondence with each capacitive fingerprint identification electrode and electrically connected; the capacitive fingerprint identification electrode and The first anode is made of the same material and arranged in the same layer. Through the setting of the capacitive fingerprint identification electrode, the capacitive fingerprint identification electrode is arranged inside the electroluminescent display panel, which reduces the thickness of the electroluminescent display panel and is conducive to realizing a thinner design; The pattern recognition electrode and the first anode are arranged in the same material and on the same layer, which can effectively reduce the manufacturing difficulty of the electroluminescence display panel and save the manufacturing cost.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an electroluminescent display panel and a display device. Background technique [0002] Organic Light Emitting Diode (OLED) display is a self-luminous display, and has the characteristics of thinness, high chromaticity, wide viewing angle and fast response speed, and has great development prospects in the field of display technology. In order to make the display have a fingerprint identification function, generally a fingerprint identification area is provided on the non-display area of ​​the display and on the display surface of the display or on the back of the display, and a fingerprint identification structure is usually provided in the fingerprint identification area; It is not conducive to the thin design of the display, and it is also not conducive to the design of the narrow frame of the display; based on this, how to realize the thin design and narrow frame design of th...
