Problems solved by technology
[0002] In the related art, optical fingerprint identification components often include a backlight, and the light emitted by the backlight passes through the cover plate. Due to the difference in refractive index between the cover plate and the air, when the light incident on the cover plate is at a certain incident angle, the light forms a refraction angle, so that The optical fingerprint sensor of the optical fingerprint recognition component receives light in a small area, and the pixel utilization rate of the optical fingerprint sensor is low

The invention discloses an optical fingerprint identification assembly and an electronic device. The optical fingerprint identification assembly of the present invention includes a cover plate and anoptical fingerprint identification module, The optical fingerprint identification module includes an optical fingerprint sensor attached to a lower surface of the cover plate, an upper surface of thecover plate including a touch region and a non-touch region, the non-touch region being formed with grooves, the touch region being disposed in correspondence with the optical fingerprint sensor, andthe grooves being configured to transmit light to an upper region of the touch region through the cover plate. The electronic device of the present invention includes a housing and an optical fingerprint identification assembly of the present invention. The optical fingerprint identification assembly and the electronic device of the invention are formed with grooves on the cover plate to increasethe incident path of light rays, As more light is transmit to that upper region of the touch area, the pixel area of the optical fingerprint sensor receiving the light reflect by the finger can be increased when the fingerprint is collected, thereby improve the pixel utilization rate of the optical fingerprint sensor.
Description
technical field [0001] The invention relates to biological identification technology, in particular to an optical fingerprint identification component and an electronic device. Background technique [0002] In the related art, optical fingerprint identification components often include a backlight, and the light emitted by the backlight passes through the cover plate. Due to the difference in refractive index between the cover plate and the air, when the light incident on the cover plate is at a certain incident angle, the light forms a refraction angle, so that The area where the optical fingerprint sensor of the optical fingerprint identification component receives light is small, and the pixel utilization rate of the optical fingerprint sensor is low. Contents of the invention [0003] Embodiments of the present invention provide an optical fingerprint identification component and an electronic device. [0004] An optical fingerprint recognition component according to ...
