The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a schematic diagram of a distribution of pixel points in a display panel according to an embodiment of the present invention is shown in fig. 1, where the display panel 10 is provided with N first pixel points 11 and M second pixel points 12, an organic material light emitting layer of each first pixel point 11 is an infrared light emitting layer, an organic material light emitting layer of each second pixel point 12 is a red light emitting layer, a green light emitting layer, or a blue light emitting layer, and N and M are positive integers.
Here, in the case of applying the display panel 10 to the terminal, the organic material light emitting layer of the first pixel point 11 on the display panel 10 is set as the infrared light emitting layer, so that the display panel 10 can provide infrared light, and the terminal does not need to provide a mounting hole on the display side thereof to mount an infrared lamp, thereby increasing the mounting area of the display panel 10 and improving the screen occupation ratio of the terminal.
In the embodiment of the present invention, the display panel 10 may be any display panel whose light emitting layer is the organic material light emitting layer, and the organic material light emitting layer of the display panel 10 may emit both infrared light and light for displaying an image, that is, the infrared light emitting layer of the first pixel 11 emits infrared light, and the red light emitting layer, the green light emitting layer and the blue light emitting layer of the second pixel 12 emit red light (R), green light (G) and blue light (B), respectively, to constitute the light for displaying an image.

under the action of external voltage, electrons and holes move towards the organic material light-emitting layer EML, when the holes and the electrons meet at the organic material light-emitting layer EML, excited excitons are formed, because the states of the excitons in the excited state are unstable, the excitons in the excited state return to the ground state from the excited state, and finally energy difference released by the excitons is converted into light energy, so that the display panel displays images;
then, in the case that the organic material light emitting layer includes the infrared light emitting layer, the energy released by the exciton may form infrared light in the infrared light emitting layer, so that the first pixel 11 emits infrared light; the energy released from the excitons can form red light in the red light emitting layer, green light in the green light emitting layer, and blue light in the blue light emitting layer, so that the second pixel 12 emits light for displaying images.
