Title:
BIOLOGICAL FEATURE DETECTION MODULE, BACKLIGHT MODULE AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/181445
Kind Code:
A1
Abstract:
An electronic device, comprising: a display (1), comprising a display panel (11) and a backlight module (10) provided below the display panel (11), the backlight module (10) being used for providing a visible light beam to the display panel (11); and a biological feature detection module (2) at least partially provided below the backlight module (10), the biological feature detection module (2) being used for receiving a detection light beam through the display panel (11) and the backlight module (10), and executing corresponding sensing according to the received detection light beam. The backlight module (10) comprises: a light guide plate (120) for transmitting and guiding a light beam; a diffusion film (130) located above the light guide plate (120), the diffusion film (130) being a quantum dot film; and a backlight source (150) provided on one side of the light guide plate (120), the backlight source (150) being used for providing a backlight beam to the light guide plate (120), the backlight beam being transmitted to the diffusion film (130) by means of the light guide plate (120), and the diffusion film (130) being used for performing wavelength conversion on the backlight beam of a specific wavelength and diffusing the backlight beam on which wavelength conversion has been performed, and for transmitting the detection light beam. Also disclosed are the biological feature detection module (2) and the backlight module (10).
