Problems solved by technology

[0002] Iris recognition generally requires an infrared light source to assist in obtaining a clear iris image. However, the iris color of different races is different, and the wavelength of the applicable infrared light source is different. The applicability of a single-wavelength infrared light source is poor.

Abstract

The invention discloses an infrared light source, an iris recognition module and a mobile terminal. The infrared light source comprises a substrate, multiple infrared light source wafer chips and a packaging body, wherein the multiple infrared light source wafer chips are arranged on the substrate, and at least two infrared light source wafer chips have different working wavelengths; and the packaging body is used for packaging the infrared light source wafer chips on the substrate. According to the infrared light source, the iris recognition module and the mobile terminal of the invention, through arranging multiple wafers with different working wavelengths in the infrared light source for users with different iris color differences and particularly different areas, different scenes and different setting requirements, on one hand, the applicability of the infrared light source is enhanced, and on the other hand, the iris recognition efficiency is improved.

Description

technical field [0001] The invention relates to the field of electronic devices, in particular to an infrared light source, an iris recognition module and a mobile terminal. Background technique [0002] Iris recognition generally requires an infrared light source to assist in obtaining a clear iris image. However, the iris color of different races is different, and the applicable infrared light source has different wavelengths. The applicability of a single-wavelength infrared light source is poor. Contents of the invention [0003] Embodiments of the present invention provide an infrared light source, an iris recognition module and a mobile terminal.
