Problems solved by technology

[0004] However, because the electrode layer in the light-emitting unit is generally made of indium tin oxide (ITO), the electrode layer is transparent, and part of the light emitted by the light-emitting unit will pass through the electrode layer and irradiate the fingerprint module, thereby causing fingerprint identification. Interference, affecting the normal identification of fingerprints

Abstract

The invention provides a display panel and a display device. The display panel comprises a substrate, a first light-shielding layer and a light-emitting layer are sequentially stacked on a first surface of the substrate, a second surface of the substrate is provided with a fingerprint module, the light-emitting layer comprises a plurality of light-emitting units arranged at intervals, the first light-shielding layer comprises a plurality of light-shielding units which are in one-to-one correspondence with the light-emitting units, and in a direction perpendicular to the substrate, the projection of the light-shielding unit is at least partially overlapped with the projection of the corresponding light-emitting unit. According to the display panel and the display device in the invention, light rays that are emitted by the light-emitting layer and irradiated on the fingerprint module can be effectively reduced, so that the interference to normal recognition of the fingerprint is reduced,and the fingerprint recognition precision is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Fingerprints are an innate feature of the human body that can be distinguished 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 determine the uniqueness of the fingerprint pattern. The display panel with the fingerprint recognition function developed therefrom has been widely applied to various display devices for personal identity verification, thereby enhancing the safety and convenience of using the display device. [0003] In the prior art, a display panel with a fingerprint recognition function includes a substrate, a thin film transistor, a light emitting layer and a fingerprint module. The thin film transistor and the light-emitting layer are arranged above the substrate, and the light-emitting layer includes...
