Abstract
A fingerprint acquisition method and an electronic device are provided. The method includes obtaining a triggering instruction for calling a fingerprint identification component of an electronic device. The method also includes in response to the triggering instruction, activating at least one pixel cell of a display screen of the electronic device corresponding to a fingerprint acquisition region. The at least one pixel cell of the display screen in a active state is used as a light source of the fingerprint identification component. Reflected light is generated with respect to the at least one pixel cell in the active state, as a finger is placed in the fingerprint acquisition region. The at least one pixel cell in the active state presents a first color of a green-series.
Claims20
A method, comprising:
- obtaining a triggering instruction for calling a fingerprint identification component of an electronic device;
- and
- in response to the triggering instruction, activating at least one pixel cell of a display screen of the electronic device corresponding to a fingerprint acquisition region, wherein:
- the at least one pixel cell of the display screen in an active state is used as a light source of the fingerprint identification component,
- reflected light is generated with respect to the at least one pixel cell in the active state, as a finger is placed in the fingerprint acquisition region, and
- the at least one pixel cell in the active state presents a first color of a green-series.
An electronic device, comprising:
- a display screen, wherein the display screen includes a display region, and the display region includes a fingerprint acquisition region;
- a fingerprint identification component, disposed on a backlight side of the display screen and opposite to the fingerprint acquisition region;
- and
- a processor, coupled to the display screen and the fingerprint identification component, wherein the processor obtains a triggering instruction for calling the fingerprint identification component of the electronic device, and in response to the triggering instruction, activates at least one pixel cell of the display screen of the electronic device corresponding to the fingerprint acquisition region, wherein:
- the at least one pixel cell of the display screen in an active state is used as a light source of the fingerprint identification component,
- reflected light is generated with respect to the at least one pixel cell in the active state, as a finger is placed in the fingerprint acquisition region, and
- the at least one pixel cell in the active state presents a first color of a green-series.
