Abstract:
A display panel having a fingerprint recognition function and a display apparatus is provided in present invention. The display panel includes a display region and a fingerprint recognition region, the display region comprising a plurality of first pixel unit, the fingerprint identification region comprising a plurality of second pixel units, each second pixel units comprising a display unit and a fingerprint identification unit; wherein the pixel aperture area of the first pixel unit is equal to the pixel aperture area of the display unit plus the pixel aperture area of the fingerprint identification unit; by the gray scale voltage compensation of the pixel in the fingerprint recognition region makes the pixel luminance in the display region and the pixel luminance in the fingerprint identification region is the same to achieve ensuring safety of an electronic device while allowing luminance uniformity of the display panel.
