1. An electronic device capable of detecting a fingerprint by optical sensing, comprising:

  • a liquid crystal display (LCD) screen that provides touch sensing operations and includes a LCD display panel structure to 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; and

    an optical sensor module located below the display panel structure to receive probe light that passes through the LCD screen to detect a fingerprint,wherein the LCD display panel structure includes a selected region that is located above the optical sensor module and is structured differently from other regions in the LCD display panel structure so as to transmit more probe light than the other regions in the LCD display panel structure to increase an amount of the received probe light at the optical sensor module.
