The embodiment of the invention discloses a display panel and a manufacturing method thereof and a display device. The display panel comprises a substrate, a driving circuit layer, a planarization layer and a conductive path, the OLED device layer comprises an anode of an OLED device, a luminescent material layer and a pixel defining layer which are electrically connected with a driving circuit layer through a conductive path, a cathode of the OLED device covering the luminescent material layer and the pixel defining layer, a cathode covering the substrate, an infrared quantum dot layer and ablack matrix, wherein the infrared quantum dot layer receives visible light emitted by the OLED device to generate infrared light, and the orthographic projection of the black matrix on the substratesurrounds the orthographic projection of the infrared quantum dot layer on the substrate; and the infrared light receiving device is used for receiving infrared light. According to the display panel,infrared light is adopted to recognize fingerprints, the safety and accuracy of fingerprint recognition are effectively improved, meanwhile, non-contact recognition can be achieved, sanitation is good, and the display panel is not prone to being affected by scratches or greasy dirt on the surface of a palm.
Description
technical field [0001] This application relates to the field of display technology. More specifically, it relates to an OLED display panel, a manufacturing method thereof, and a display device. Background technique [0002] Fingerprint recognition technology is to collect the fingerprint image of the human body through the fingerprint sensor, and then compare it with the existing fingerprint imaging information in the system to judge whether it is correct or not, and then realize the technology of identity recognition. Due to its ease of use and the uniqueness of human fingerprints, fingerprint recognition technology has been widely used in various fields, such as security inspection fields such as public security bureaus and customs, building access control systems, and consumer products such as personal computers and mobile phones, etc. [0003] Fingerprint identification technology first requires the ability to image fingerprints. The implementation methods of fingerprin...
