Abstract

The invention discloses a display panel and a display device. The display panel comprises a color film substrate, an array substrate and collimating holes, wherein the array substrate is opposite to the color film substrate, the array substrate comprises a light sensing unit group; one light sensing unit group comprises n light sensing units, n is a positive integer, n is larger than or equal to 2, and all the light sensing units in the same light sensing unit group are connected in series; and the collimating holes are in one-to-one correspondence with the light sensing units. At least two light sensing units are connected in series, and a distance between the light sensing units can be adjusted through the design, so that overlapping of detection areas corresponding to the light sensingunits (also collimating holes) is realized, the same valley or ridge can be detected by using optical signals received by the at least two light sensing units, the semaphore used for detecting one valley or the ridge is increased without increasing the sizes of the collimating holes, and the detection precision is improved.

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...
