A method for enabling an electronic device to receive a fingerprint data, the electronic device comprising a display unit, wherein the display unit comprises a green sub-pixel, a blue sub-pixel, a red sub-pixel and a sensing unit, and the method comprises following steps:
- the green sub-pixel of the display unit being in an on state, the blue sub-pixel and the red sub-pixel of the display unit being in off state;
- producing a visible light by the display unit;
- using the sensing unit to sense a reflected portion of the visible light;
- and
- receiving the fingerprint data from the sensing unit.
An electronic device, comprising:
- a display unit comprising a plurality of first conducting wires and a plurality of second conducting wires respectively extending along different directions, wherein the plurality of first conducting wires are intersected with the plurality of second conducting wires to define a plurality of sub-pixels;
- and
- a plurality of photoelectric converting elements respectively disposed in one of the plurality of sub-pixels,
- wherein a ratio of a total number of the plurality of photoelectric converting elements to a total number of the plurality of sub-pixels is in a range from 1/3 to 2/3.
