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 18):
A method for operating an electronic device to detect a fingerprint by optical sensing, wherein the electronic device includes 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, and an optical sensor array of optical detectors located under the display panel, the method comprising:\n directing a first illumination probe beam to illuminate a designated fingerprint sensing area over the top transparent layer in a first illumination direction and to enter a user finger over the designated fingerprint sensing area to produce first scattered probe light by scattering of tissues inside the finger that propagates towards and passes the top transparent layer by transmission through internal tissues of ridges and valleys of the finger to carry both (1) a first 2-dimensional transmissive pattern representing a fingerprint pattern formed by bridges and valleys of the finger, and (2) a first fingerprint topographical pattern that is associated with the illumination of internal tissues of ridges and valleys of the finger in the first illumination direction and is embedded within the first 2-dimensional transmissive pattern; operating the optical sensor array to detect transmitted part of the first scattered probe light that passes through the top transparent layer and the display panel to reach the optical sensor array so as to capture both (1) the first 2-dimensional transmissive pattern, and (2) the first fingerprint topographical pattern; directing a second illumination probe beam, while turning off the first illumination light source, to illuminate the designated fingerprint sensing area over the top transparent layer in a second, different illumination direction and to enter the user finger to produce second scattered probe light by scattering of tissues inside the finger that propagates towards and passes the top transparent layer by transmission through internal tissues of ridges and valleys of the finger to carry both (1) a second 2-dimensional transmissive pattern representing the fingerprint pattern, and (2) a second fingerprint topographical pattern that is associated with the illumination of the internal tissues of ridges and valleys of the finger in the second illumination direction and that is embedded within the second 2-dimensional transmissive pattern, wherein the second topographical pattern is different from the first topographical pattern due to different beam directions of the first and second illumination probe beams; operating the optical sensor array to detect transmitted part of the second scattered probe light that passes through the top transparent layer and the display panel to reach the optical sensor array so as to capture both (1) the second 2-dimensional transmissive pattern, and (2) the second fingerprint topographical pattern; constructing a detected fingerprint pattern from the first and second transmissive patterns; and processing the first and second fingerprint topographical patterns to determine whether the detected fingerprint pattern is from a natural finger.
