Abstract
A fingerprint sensor integrated display using a holographic optical element and a recording and reconstruction method of the holographic optical element are disclosed. The fingerprint sensor integrated display includes a display panel on which an input image is displayed, a transparent substrate disposed on the display panel, and a light entering element configured to irradiate light from a light source onto the transparent substrate. A particular type of visual information is reconstructed through a holographic element at a location of the light entering element.
