Abstract:
Devices and optical sensor modules are provided for provide on-screen optical sensing of fingerprints by using an under-LCD or OLED screen optical sensor module that captures and detects returned light.

Claim (Index 1):
An electronic device capable of detecting a fingerprint by optical sensing, comprising:\n a liquid crystal display (LCD) screen that provides touch sensing operations and includes a LCD display panel structure to display images; a LCD backlighting light module coupled to the LCD screen to produce backlighting light to the LCD screen for display images; a top transparent layer formed over the device screen as an interface for being touched by a user for the touch sensing operations and for transmitting the light from the display structure to display images to a user; an optical sensor module located below the LCD display panel structure to include an optical sensor array to receive probe light that is reflected from the top transparent layer and passes through the LCD screen to detect a fingerprint; one or more probe light sources, separate from the LCD backlighting light module, located under the LCD display panel structure, to produce the probe light that passes through he LCD display panel structure to illuminate a designated fingerprint sensing area on the a top transparent layer to be visibly different from a surrounding area of the top transparent layer for a user to place a finger for optical fingerprint sensing; and a device control module coupled to the optical sensor module to process an output of the optical sensor module to determine whether a detected fingerprint by the optical sensor module matches a fingerprint an authorized user, in addition to detecting fingerprints, also detect a biometric parameter different form a fingerprint by optical sensing to indicate whether a touch at the top transparent layer associated with a detected fingerprint is from a live person, wherein the optical sensor module includes one or more optical filtering layers to transmit probe light for optical sensing of fingerprints while blocking background day light at optical wavelengths longer than the probe light, and wherein the optical sensor module includes one or more layers between the LCD screen and the optical sensor array to be sufficiently thick to reduce undesired Moir\u00e9 patterns.
