Abstract:
Devices and optical sensor modules are provided for provide on-screen optical sensing of fingerprints by using an under-screen optical sensor module that captures and detects optical transmissive patterns in probe light that transmits through the internal finger tissues associated with the external fingerprint pattern formed on the outer finger skin to provide 3-dimensional topographical information for improved optical fingerprint sensing.

Claim (Index 1):
An electronic device capable of detecting a fingerprint by optical sensing, comprising:\n a display panel that displays images; a top transparent layer formed over the display panel as an interface for user touch operations and for transmitting the light from the display panel to display images, the top transparent layer including a designated fingerprint sensing area for a user to place a finger for fingerprint sensing; an optical sensor module located below the display panel and underneath the designated fingerprint sensing area on the top transparent layer to receive light from the top transparent layer to detect a fingerprint, wherein the optical sensor module includes an optical sensor array of optical detectors to convert the received light that carries a fingerprint pattern of the user into detector signals representing the fingerprint pattern; extra illumination light sources, separated from the display panel and located outside the optical sensor module at different locations to produce different illumination probe beams to illuminate the designated fingerprint sensing area on the top transparent layer in different illumination directions, each extra illumination light source structured to produce probe light in an optical spectral range with respect to which tissues of a human finger exhibit optical transmission to allow probe light in each illumination probe beam to enter a user finger over the designated fingerprint sensing area on the top transparent layer to produce scattered probe light by scattering of tissues inside the finger that propagates towards and passes the top transparent layer to carry both (1) fingerprint pattern information and (2) different fingerprint topographical information associated with the different illumination directions, respectively, caused by transmission through internal tissues of ridges and valleys of the finger; and a probe illumination control circuit coupled to control the extra illumination light sources to sequentially turn on and off in generating the different illumination probe beams at different times, one beam at a time, so that the optical sensor module located below the display panel is operable to sequentially detect the scattered probe light from the different illumination probe beams to capture both (1) the fingerprint pattern information and (2) the different fingerprint topographical information associated with the different illumination directions, respectively.
