1. A fingerprint identification display comprising:
a display panel; and
a processor,
wherein the display panel includes a plurality of pixels arranged in a form of a two-dimensional matrix,
wherein each pixel of the plurality of pixels comprises:
a plurality of subpixels within the pixel that are configured to emit light based on a first signal received from the processor; and
an optical sensor within the pixel that is configured to receive the light emitted from the plurality of subpixels and is reflected from a fingerprint and generate a second signal,
and wherein the processor is configured to drive at least some optical sensors among a plurality of optical sensors within the plurality of pixels to operate responsive to a touch of the display panel not being detected, and drive all optical sensors within at least one pixel included in a touch region that is touched by a user when the touch of the display panel is detected, and identifies the fingerprint of the user based on the second signal received from the pixel.
