Abstract

The invention discloses a fingerprint identification display panel and display device. A plurality of infrared light emitting units based on the infrared photosensitive effect are integrated on a driving circuit backboard, and a plurality of infrared photosensitive sensing units are arranged inside a protective cover plate above a packaging component for packaging an electroluminescence unit and the infrared light emitting units, namely between the protective cover plate and a film layer of the infrared light emitting units. When a finger of a user is close to the surface of the display panel, because the skin surface of the finger has uneven ridges and valleys, the intensities of infrared light emitted by the infrared light emitting units, irradiated to the ridges and valleys of the finger and reflected to the infrared photosensitive sensing units are different, and the light intensity difference is converted into a current signal difference to detect fingerprints; and the infrared photosensitive sensing units for detecting the fingerprints based on the infrared photosensitive effect are unlikely to interfere with internal components of the display panel, so that high-quality fingerprint detection is easily realized.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a fingerprint identification display panel and a display device. Background technique [0002] With the rapid development of display technology, display panels with a fingerprint recognition function have gradually spread in people's lives. At present, fingerprint recognition display panels generally adopt capacitive structure to realize the function of fingerprint recognition. For example, in-cell fingerprint recognition display The fingerprint identification component is likely to generate parasitic capacitance with the components inside the display panel, so that the fingerprint identification detection signal and the display signal interfere with each other, thereby affecting the quality of fingerprint identification. Contents of the invention [0003] In view of this, the embodiments of the present invention provide a fingerprint identification display panel and a displa...
