Display device and fingerprint identification method thereof and electronic device

Abstract

An embodiment of the invention discloses a display device and a fingerprint identification method thereof and an electronic device. The display device comprises a display panel and a cover plate arranged on the display panel. The display panel comprises an array substrate, an organic light-emitting layer arranged at one side, facing to the cover plate, of the array substrate, and a fingerprint identification array. The organic light-emitting layer comprises a plurality of organic light-emitting structures. A first surface, away from the array substrate, of the cover plate is a light output surface of the display device. In the fingerprint identification stage, the plurality of organic light-emitting structures realize displacement and light emitting according to a first light-emitting dot matrix; the distance between any two adjacent organic light-emitting structures in the first light-emitting dot matrix is larger than or equal to minimum no-crosstalk distance; and the minimum no-crosstalk distance is the maximum radius of a coverage area formed on the fingerprint identification array when light emitted by any one organic light-emitting structure is reflected by the first surface of the cover plate. Fingerprint identification units are not influenced by crosstalk of other organic light-emitting structures, so that fingerprint recognition accuracy of the display device can be improved.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular to a display device, a fingerprint identification method thereof, and electronic equipment. Background technique [0002] Fingerprints are inherent to each person and are unique. With the development of technology, a variety of display devices with fingerprint recognition functions appear on the market, such as mobile phones, tablet computers, and smart wearable devices. In this way, before operating the display device with the fingerprint recognition function, the user only needs to touch the fingerprint recognition sensor of the display device with a finger to perform authority verification, which simplifies the authority verification process. [0003] In the existing display device with fingerprint identification function, when the light emitted by the fingerprint identification light source is reflected by the finger, it will be irradiated on a plurality of fing...
