A heart rate detection method, a heart rate detection apparatus and an electronic device are provided. The heart rate detection method includes: acquiring a heart rate detection light signal, where the heart rate detection light signal is a light signal that is emitted upward from a ring light-emitting region of a display screen and enters a capturing region after being reflected by a finger of a user, and an intermediate region surrounded by the ring light-emitting region is a non-light-emitting region (); and determining a heart rate of the user according to the heart rate detection light signal (). According to the method, the accuracy of heart rate detection could be effectively improved.

Heart rate detection method, heart rate detection apparatus and electronic device

An under-screen optical fingerprint recognition system, a backlight module, a display screen, and an electronic device are provided. The under-screen optical fingerprint recognition system is applied to a display screen with a backlight module, the under-screen optical fingerprint recognition system includes a fingerprint recognition chip and a first light source, the wavelength of fingerprint detecting light emitted by the first light source is within a preset wavelength range, the fingerprint recognition chip is arranged below the backlight module for receiving light carrying fingerprint information that passes through the backlight module and has a diffusivity smaller than or equal to a set threshold, and the light carrying fingerprint information is reflected by a finger from the light emitted by the first light source. The system may be applied to a display screen with a backlight module to meet the requirements of the LCD screen for under-screen fingerprint recognition.

Under-screen optical fingerprint recognition system, backlight module, display screen, and electronic device

The present application discloses a method of fingerprint identification, a fingerprint identification apparatus, a fingerprint identification chip and a terminal device. The method includes: detecting a value of a light signal reflected by a finger when a touch signal of the finger is received on a fingerprint identification area; determining whether the value of the light signal is within a preset numerical range; and determining a fingerprint contacting the fingerprint identification area is a live fingerprint if the value of the light signal is within the numerical range. Therefore, when a finger presses a fingerprint identification area, it is judged that a fingerprint contacting the fingerprint identification area is a live fingerprint or a non-live fingerprint through a value of a light signal reflected by the finger, thereby improving security of a fingerprint password.
