Abstract

The invention provides a display panel and a display device, which relate to the field of display technology and are used for improving the accuracy of fingerprint identification. Scanning lines and data lines of the display panel intersect to define a plurality of first pixel circuits and second pixel circuits arranged in a matrix along the row direction and the column direction; the display area of ​​the display panel includes a fingerprint identification area and a non-fingerprint identification area; The fingerprint identification area also includes a plurality of first organic light-emitting devices; the plurality of first organic light-emitting devices are arranged in a matrix along the row direction and the column direction; the non-fingerprint identification area includes a plurality of second organic light-emitting devices; a plurality of second organic light-emitting devices The light-emitting devices are arranged in a non-matrix along the row direction and the column direction; each first pixel circuit includes a first capacitor unit, and the first capacitor unit includes a first plate; the first plate of each first capacitor unit is displayed The projection of the plane where the panel is located is located within the projection of the corresponding first electrode on the plane where the display panel is located. The above-mentioned display panel is used to realize image 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] For a display panel with fingerprint recognition function, when performing fingerprint recognition, the light emitted by the light source is reflected into the fingerprint recognition unit through the touch body, and the fingerprint recognition unit recognizes different fingerprints according to the difference in the reflected light intensity of the valleys and ridges of the fingerprint. [0004] At present, in order to prevent t...
