Abstract

The invention provides a display panel and a display device, and relates to the field of display technology, aiming at improving the precision of fingerprint identification. The display panel comprises a display area and a non-display area, and further comprises a plurality of pixel driving circuits, wherein the display area comprises a plurality of display units which are distributed in an arrayform; the pixel driving circuits are correspondingly connected to the display units; the display area comprises a fingerprint identification area; the display units, which are arranged in the fingerprint identification area, include at least one first display unit; the pixel driving circuits include at least one first pixel driving circuit which is electrically connected to the at least one firstdisplay unit; and the at least one first pixel driving circuit comprises a storage capacitor and a plurality of thin-film transitors, wherein the storage capacitor and / or the at least one thin-film transitor are / is arranged in the non-display area. The display panel is used for implementing picture display.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. 【Background technique】 [0002] In recent years, with the continuous development of display technology, more and more display devices adopt fingerprint recognition to realize user privacy protection. When a user operates a display device with a fingerprint identification function, he only needs to touch the display screen with his finger to realize authority verification, and the operation is simple. [0003] When the existing display panel with fingerprint identification function performs fingerprint identification, the light emitted by the light source is reflected into the fingerprint identification unit through the touch body, and the fingerprint identification unit identifies different fingerprints according to the difference in the reflected light intensity of the valleys and ridges of the fingerprints. However, based on the...
