Abstract

The embodiment of the invention provides a display panel and a display device. The display panel comprises a display area and a non-display area, wherein a fingerprint recognition driving chip and a display driving chip are arranged in a non-display area of the display panel; a plurality of pixels arranged in an array mode are arranged in a display area on one side of a substrate of the display panel, and fingerprint recognition elements and fingerprint recognition driving circuits electrically connected with the fingerprint recognition elements are arranged in gaps between the pixels; the display area of the display panel further comprises a common electrode layer; the common electrode layer comprises a common electrode of each pixel and a first electrode of each fingerprint recognition element, and the first electrodes of the fingerprint recognition elements are insulated from the common electrodes of the pixels; a first electrode of the fingerprint recognition element and a power supply signal input end and a scanning signal input end of the fingerprint recognition driving circuit are electrically connected with the fingerprint recognition driving chip, and a second electrode ofthe fingerprint recognition element is electrically connected with the fingerprint recognition driving circuit; and the display driving chip is electrically connected with the common electrode.

Description

Technical field [0001] The present invention relates to the field of display technology, and in particular to a display panel and a display device. Background technique [0002] Fingerprints have become synonymous with biometric identification due to their lifetime immutability, uniqueness and convenience. Especially in the display device, functions such as unlocking and payment of the display device can be realized by performing fingerprint recognition on the user. [0003] At present, in order to enable the display to realize the fingerprint recognition function, a fingerprint recognition element and a fingerprint recognition drive circuit are usually integrated in the display panel of the display, wherein the fingerprint recognition drive circuit can drive the fingerprint recognition element so that the display panel can realize the fingerprint recognition function. In the prior art, a display panel with fingerprint recognition function is usually provided with two driving chip...
