US 2021/0341702 A1 · Lens, Active Light Emitting Module, and Terminal

Abstract

The present invention provides a lens, an active light emitting module, and a terminal and relates to the field of electronic terminal device technologies, so as to protect a conductive layer on an optical element, and reduce a risk that the conductive layer is damaged by static electricity. The lens includes a lens tube and the optical element mounted in the lens tube. The lens tube has a top surface, and a conductive layer is disposed on a surface that is of the optical dement and that faces a side on which the top surface is located. The lens further includes: an antistatic structure disposed on the top surface, and an electrostatic conducting wire disposed in a tube wall or on an inner surface or an outer surface of the lens tube. One end of the electrostatic conducting wire is electrically connected to the antistatic structure, and the other end is grounded. The lens is mounted in the active light emitting module, and the active light emitting module is applied to the terminal, to assist the terminal in implementing a function such as 3D sensing.
