Fingerprint recognizer, fingerprint recognition method, light emitter device, optical sensor, and display device
A fingerprint recognizer, a fingerprint recognition method, a light emitter device, an optical sensor and a display device are provided. The fingerprint recognizer includes a pressure detector unit, a light emitter unit, a light sensor unit, and a fingerprint analyzer unit. The pressure detector unit is configured to detect the strength at which a finger presses a display screen, and send a signal to the light emitter unit according to the strength. The light emitter unit is configured to emit a light signal under the control of the signal of the pressure detector unit. The light sensor unit is configured to receive a light-reflection signal formed by the light signal reflected by the finger, convert the light-reflection signal into an electrical signal and output the electrical signal to the fingerprint analyzer unit. The fingerprint analyzer unit is configured to determine fingerprint information according to the received electrical signal.
