The first electrode 310 and the second electrode 320 excite the light emitting layer 320 to generate visible light under the action of the driving voltage, and the pixel defining layer 20 is used for isolating each sub-pixel unit 30. The light emitting layer 320 excites the sub-pixel unit 30 to generate light of different colors according to the magnitude of the driving voltage. The sub-pixel units 30 can be divided into red sub-pixels, green sub-pixels and blue sub-pixels according to different materials. The light emitting layer 320 excites the red, green and blue sub-pixels to emit red, green and blue light, respectively, by the driving voltage.
Optionally, the first electrode 310 is an anode and the second electrode 320 is a cathode.

In the bottom emission mode of the display panel, the photoluminescent unit 40 may be located on a side of the first electrode 310 facing away from the second electrode 330 or between the first electrode 310 and the light-emitting layer 320, and the infrared identification unit 50 is located between the pixel defining layer 20 and the substrate 10 around the sub-pixel unit 30 having the photoluminescent unit 40 on the light-emitting side. When the light emitting mode of the OLED display panel is dual-sided light emitting, the first electrode 310 and the second electrode 330 are both transparent electrodes, and the first electrode 310 and the second electrode 330 can be made of materials such as tin fume oxide and tin zinc oxide, so that light emitted from the light emitting layer 320 can penetrate through the first electrode 310 and the second electrode 330, and dual-sided light emitting of the display panel is further achieved.

When the infrared recognition unit 50 receives infrared light reflected by human fingerprints, the infrared light is reflected by a human face and is collected by the infrared recognition unit in the display panel, a photoelectric signal is converted by the signal data conversion module, and the photoelectric signal is processed and compared with the human face information in the database in the equipment data processing module, so that functions of unlocking equipment and the like are realized.
It should be noted that, the embodiment of the present invention does not limit the infrared identification function, and any display panel using the infrared identification function provided in the embodiment of the present invention is the protection scope of the embodiment of the present invention.
According to the technical scheme, the photoluminescence unit is arranged on the light emitting side of the sub-pixel unit of the display panel to excite red light, the infrared identification unit is arranged on one side, close to the light emitting direction, of the pixel limiting layer corresponding to the sub-pixel unit of the photoluminescence unit on the light emitting side, the infrared identification unit is achieved by utilizing the light source in the OLED display panel, the thickness of the display panel is reduced, and the accuracy of an identification result is improved.
On the basis of the above embodiment, referring to fig. 3, the display panel further includes an infrared filter layer 60, and the infrared filter layer 60 is located on one side of the infrared identification unit 50 close to the light emitting direction.
Since the light emitted from the light emitting side of the display panel includes light beams of different colors, the reflected light reaches the infrared recognition unit 50 including light beams of other colors in addition to the infrared light. Through set up infrared filtering layer 60 in one side that infrared identification unit 50 is close to the light-emitting direction, the light beam of other colours is filtered to accessible infrared filtering layer 60, and only infrared light reachs infrared identification unit 50, avoids other light sources to disturb infrared identification unit 50's identification result, improves infrared identification result's rate of accuracy.
It should be noted that the infrared filter layer 60 is used to filter light beams of different colors and only allow infrared light to pass through, the embodiment of the present invention does not limit the material of the infrared filter layer 60, and any infrared filter layer 60 that can filter infrared light is within the protection scope of the embodiment of the present invention.

Because a part of the light emitted from the sub-pixel unit 30 in the display panel is used for the display function, the other part of the light passes through the photoluminescence unit 40 to emit infrared light and then reaches the infrared identification unit 50 through reflection, and the infrared identification unit 50 performs infrared identification. The vertical projection of the photoluminescence unit 40 on the substrate 10 is positioned in the vertical projection of the sub-pixel unit 30 on the substrate 10 and is not overlapped with the vertical projection of the sub-pixel unit 30 on the substrate 10, so that the display panel has functions of display and the like, and has an infrared recognition function. If the vertical projection of the photoluminescence unit 40 on the substrate 10 completely coincides with the vertical projection of the sub-pixel unit 30 on the substrate 10, the light emitted from the light emitting side of the sub-pixel unit 30 only emits red light after passing through the photoluminescence unit 40, and the display panel can only be used for infrared identification, cannot display, and further cannot realize functions such as displaying of infrared identification results.
It should be noted that the vertical projection of the photoluminescent unit 40 on the substrate 10 can satisfy the functions of display and infrared recognition as long as the photoluminescent unit is located in the vertical projection of the sub-pixel unit 30 on the substrate 10, and the embodiment of the present invention does not limit the specific size and shape of the photoluminescent unit 40.
