Abstract: The present disclosure related to an optical fingerprint identification display and a driving method thereof. In the optical fingerprint identification display and the driving method thereof, the fingerprint identification display includes: a display panel and a processor. The display panel includes a plurality of pixels arranged in a two-dimensional matrix. The pixel includes: at least one subpixel which emits light on the basis of a first signal received from the processor; and an optical sensor which receives the light emitted from the subpixel and is reflected from a fingerprint and generates a second signal. The processor determines a touch region on the display panel, and transmits the first signal to one or more pixels included in the touch region, and identifies the fingerprint of the user on the basis of the second signal received from the pixel.
