Description

technical field

[0001] The present invention relates to the field of display technology, and more specifically, to a display panel and a display device. Background technique

[0002] With the rapid development of display technology, display panels with fingerprint recognition functions have gradually spread in people's lives, and fingerprint recognition is widely used in display screens of electronic devices such as mobile phones, personal digital assistants, and computers. Fingerprint is an invariable feature that is unique and distinguishable from others. It consists of a series of ridges and valleys on the skin surface of the fingertips. The details of these ridges and valleys usually include the bifurcation of ridges, the Details such as ends, arches, tented arches, left-handed, right-handed, helical or double-handed, these details determine the uniqueness of the fingerprint pattern.

[0003] In the prior art, the fingerprint identification unit of the liquid crystal di...
