Abstract

The invention discloses a display panel and a driving method thereof, and a display device. The display panel comprises a substrate, a driving circuit positioned on the substrate, a plurality of microlight emitting diodes positioned on one side, deviating from the substrate, of the driving circuit and electrically connected with the driving circuit, a common electrode layer located on one sides,deviating from the substrate, of the micro light-emitting diodes and electrically connected with the light-emitting diodes, an insulating layer located on the side, deviating from the substrate, of the common electrode layer, and a plurality of fingerprint recognition electrodes located on the side, deviating from the substrate, of the insulating layer. According to the display panel provided in the invention, the fingerprint recognition electrodes are arranged on one side, deviating from the substrate, of the common electrode layer; and a touch position of a finger and a fingerprint pattern of the finger can be determined according to a capacitance value of each fingerprint recognition electrode, and the common electrode layer can be driven in a time-sharing manner so that fingerprint recognition is realized on the basis of meeting normal display requirements, and full-screen fingerprint recognition can also be realized.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a driving method thereof and a display device. Background technique [0002] With the rapid development of computers and networks, people have put forward higher requirements for the accuracy, security and practicability of identity authentication. Due to the non-repeatable characteristics of the human body's physical characteristics, more and more people are turning their attention to biometric technology, using the physical characteristics of the human body for identification. Among them, fingerprint recognition technology is the earliest and most widely used. Fingerprint recognition technology Making full use of the universality, uniqueness and permanent biological characteristics of fingerprints, it has gradually replaced the traditional identification methods based on signs and numbers, and is currently widely used in industries such as network, banking, fi...
