Abstract

Provided are a display panel and display device. The display panel includes a display region and a border region. The border region is provided with a display cascade scanning circuit and a fingerprint-identification cascade scanning circuit. The display region is provided with multiple display scanning lines and multiple fingerprint scanning lines. The display cascade scanning circuit is electrically connected to the multiple display scanning lines and configured to output display scanning signals to the multiple display scanning lines respectively. The fingerprint-identification cascade scanning circuit is electrically connected to the multiple fingerprint scanning lines and configured to generate and output fingerprint scanning signals to the multiple fingerprint scanning lines respectively. The fingerprint-identification cascade scanning circuit includes a first fingerprint-identification cascade scanning circuit and a second fingerprint-identification cascade scanning circuit that are disposed at two opposite sides of the display region.
