Abstract
The present disclosure relates to a flat panel display embedding an optical imaging sensor such as a fingerprint image sensor. The present disclosure provides a flat panel display embedding an image sensor comprising: a display panel including a display area and a non-display area; and a directional optical unit having a length and a width corresponding to the display panel and a thickness, and attached on a top surface of the display panel, wherein the directional optical unit includes: a first cover plate and a second cover plate having a size corresponding to the length and the width and joining each other by a first low refractive layer between the first cover plate and the second cover plate; a light radiating film corresponding to the display area under the second cover plate; a light incident film disposed outside of the display area at one lateral side of the light radiating film, under the second cover plate; a second low refractive layer disposed under the light radiating film and the light incident film, and attached on the top surface of the display panel; and a light source disposed at the lateral side of the display panel as facing with the light incident film.
