Abstract

The invention discloses an OLED unit and a manufacturing method thereof, a display panel and a display device, and belongs to the technical field of display. The OLED unit includes a first electrode layer disposed on a substrate base plate, a near-infrared emitting layer, a barrier layer, a red light emitting layer and a second electrode layer. The near-infrared emitting layer is disposed on the side, away from substrate base plate, of the first electrode layer and used for emitting near-infrared light; the barrier layer is disposed on the side, away from the substrate base plate, of the near-infrared emitting layer and made of a conductive material; the red light emitting layer is disposed on the side, away from the substrate base plate, of the barrier layer and used for emitting red light; the second electrode layer is disposed on the side, away from the substrate base plate, of the red light emitting layer, and the polarity of the second electrode layer is opposite to that of the first electrode layer. The manufacturing process of the display panel is simplified, and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED unit and a manufacturing method thereof, a display panel, and a display device. Background technique [0002] In an organic light-emitting diode (English: Organic Light-Emitting Diode; abbreviation: OLED) display panel with a fingerprint recognition function, each light-emitting unit is provided with: an OLED unit for display and a near-infrared OLED unit, and the OLED unit for display can emit Light for display, the near-infrared OLED unit can emit light for fingerprint recognition. [0003] In the related art, the OLED unit for display and the near-infrared OLED unit are independently arranged on the display panel. And the display OLED unit and the near-infrared OLED unit both include an anode, a hole injection layer, a hole transport layer, an electroluminescent film layer, an electron transport layer, an electron injection layer, a cathode, and the like.
