Abstract

The invention discloses a display panel and a display device. The display panel comprises: a color filter substrate; an array substrate arranged opposite to the color filter substrate, the array substrate includes photosensitive unit groups, and one photosensitive unit group includes n photosensitive units, n is a positive integer, and n≥2, and all the photosensitive units in the same photosensitive unit group are connected in series; it also includes a collimating hole, and the collimating hole is connected to the said photosensitive unit. There is a one-to-one correspondence between the photosensitive units. In the present invention, at least two photosensitive units are connected in series, and the distance between the photosensitive units can be adjusted through design, so that the detection areas corresponding to the photosensitive units (which are also collimation holes) overlap, and the use of at least two photosensitive units can be realized. The received optical signal detects the same valley or ridge, which is equivalent to increasing the amount of signal used to detect a valley or ridge without increasing the size of the collimation hole, which is beneficial to improving the detection accuracy.

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] Display panels with fingerprint identification functions have gradually spread in people's lives, and fingerprint identification 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] The in-screen fingerprint recognition technology of the display panel is mainly by making photosensitive devices on the ar...
