Abstract
An electronic device is provided. The electronic device includes a cover plate, a main board, an iris camera, an infrared lamp, a polarizing member. The iris camera is coupled with the main board and arranged on a side of the main board facing the cover plate. The infrared lamp is coupled with the main board and arranged on the side of the main board facing the cover plate. The infrared lamp is spaced apart from the iris camera. The polarizing member is arranged between the infrared lamp and the cover plate to reduce an angle of infrared light emitted from the infrared lamp.
Claims18
An electronic device, comprising:
- a cover plate;
- a main board arranged at a rear side of the cover plate and spaced apart from the cover plate;
- an iris camera coupled with the main board and arranged on a side of the main board facing the cover plate;
- an infrared lamp coupled with the main board and arranged on the side of the main board facing the cover plate, the infrared lamp being spaced apart from the iris camera;
- and
- a polarizing member arranged between the infrared lamp and the cover plate to reduce an angle of infrared light emitted from the infrared lamp,
- wherein a thickness of the polarizing member decreases gradually in a radially outward direction from a central axis of the infrared lamp, and
- wherein an orthographic projection area of the polarizing member on the cover plate is larger than an orthographic projection area of the infrared lamp on the cover plate.
An electronic device, comprising:
- a cover plate;
- a polarizing member arranged to a rear side of the cover plate;
- a main board arranged behind the polarizing member and spaced apart from the polarizing member;
- an iris camera coupled with the main board and arranged on a side of the main board facing the cover plate;
- and
- an infrared lamp coupled with the main board and arranged on the side of the main board facing the cover plate, the infrared lamp being spaced apart from the iris camera,
- wherein the infrared lamp is arranged opposite to the polarizing member, and the polarizing member is configured to polarize infrared light emitted from the infrared lamp to reduce an angle of the infrared light emitted from the infrared lamp,
- wherein a thickness of the polarizing member decreases gradually in a radially outward direction from a central axis of the infrared lamp, and
- wherein an orthographic projection area of the polarizing member on the cover plate is larger than an orthographic projection area of the infrared lamp on the cover plate.
An electronic device, comprising:
- a housing;
- a cover plate connected to the housing to enclose an inner space therebetween;
- a display screen and a polarizing member arranged to a rear side of the cover plate, and spaced apart from each other;
- an infrared lamp arranged in the inner space and facing the polarizing member;
- and
- an iris camera arranged in the inner space and spaced apart from the infrared lamp,
- wherein the polarizing member is configured to polarize infrared light emitted from the infrared lamp to reduce an angle of the infrared light emitted from the infrared lamp,
- wherein a thickness of the polarizing member decreases gradually in a radially outward direction from a central axis of the infrared lamp, and
- wherein an orthographic projection area of the polarizing member on the cover plate is larger than an orthographic projection area of the infrared lamp on the cover plate.
