Abstract

Embodiments of the present invention provide a display panel and a display device, which relate to the field of display technology and can solve the problem that a display device with an iris recognition function needs to be separately provided with an infrared light source. The display panel includes a display area, and the display area includes an iris identification area; the display panel includes a light conversion layer arranged on the iris identification area; the light conversion layer is used to convert visible light incident on it into infrared light, the infrared light is emitted from the display side of the display panel. Used in display devices with iris recognition function.

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] Iris recognition technology is to confirm the identity by photographing the iris of the human eye, and it is an identity authentication technology based on biometrics. Since the security of iris recognition is much higher than that of fingerprint recognition, face recognition, etc., iris recognition is a major development trend of current user identification. [0003] Currently, some display devices have an iris recognition function. In order to realize the iris recognition function, the display device includes a display panel, an infrared light source emitting infrared light, a camera, a processor, and the like. Since the current display device with the iris recognition function requires a separate infrared light source, the structure of the display device is complicated, which is not suitable for the...
