Problems solved by technology

Under-screen fingerprint recognition uses virtual buttons for fingerprint recognition, but it is still unavoidable to use external fingerprint recognition sensors. The mainstream fingerprint recognition sensors are all made of silicon-based CMOS (complementary metal oxide semiconductor) technology, and the production of large-area fingerprint recognition sensors. Cost limits its entry into the field of full-screen fingerprint recognition

Abstract

The invention provides a display panel and a preparation method thereof, a display device and a fingerprint identification method, and belongs to the technical field of display. The display panel comprises a substrate, a plurality of pixel units and a plurality of photosensitive units. The photosensitive units and the pixel units are arranged on the same side of the substrate, and any photosensitive unit is arranged between the adjacent pixel units. The display panel can realize in-screen fingerprint identification, and is convenient for improving the screen-to-body ratio.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular to a display panel, a manufacturing method thereof, a display device, and a fingerprint identification method. Background technique [0002] Fingerprint recognition technology is the most widely used technology in biometric technology. At present, the fingerprint image acquisition equipment mainly includes optical scanning equipment (such as micro-prism matrix), temperature-sensitive fingerprint sensor, semiconductor fingerprint sensor (such as capacitive fingerprint sensor and pressure-sensitive fingerprint sensor), optical fingerprint sensor (such as small hole imaging Fingerprint sensor and collimator fingerprint sensor) and ultrasonic fingerprint scanning equipment five categories. Among them, the application of semiconductor fingerprint sensors, especially capacitive fingerprint recognition technology, is the most common. [0003] At present, the fingerprint rec...
