Abstract:
A fingerprint identification display device, includes: a display panel having a plurality of display units defined therein, and at least some of the plurality of display units are located in a fingerprint identification region, each of which comprises display subpixels and an identification subpixel; a light guide plate; one or more light emitting components configured to make detection light emitted therefrom travel in the light guide plate in a total reflection manner; a first polarizer comprising a first region and a second region with perpendicular polarization directions, and a second polarizer comprising a third region and a fourth region with perpendicular polarization directions, wherein the first region and the third region correspond to the display subpixels and have perpendicular polarization directions, and the second region and the fourth region correspond to the identification subpixel; and a photosensitive sensing unit disposed at the second polarizer, and corresponding to the identification subpixel.
