    Abstract: The disclosure relates to a viewing angle switchable back light unit wherein a general mode and a privacy mode in a liquid crystal display can be selected. A thin film type back light unit includes a light guide film, a light radiator, a first light source, and a light collimator. The light guide film includes a light entering part at one side, a light guiding part extending from the one side to an opposite side of the one side, and a light radiating part on one plane surface. The light radiator is on the light radiating part. The first light source faces the light entering part. The light collimator is on the light entering part facing the first light source. The light collimator receives an expanding light from the first light source, converts the expanding light into collimated light, and provides the collimated light to the light entering part.

    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.

    Abstract: Disclosed herein is a display device capable of recognizing a fine fingerprint without a complicated construction such as a bulky optical device. The display device comprises a display panel having a display area and a non-display area outside the display area; a light source disposed below the non-display area of the display panel to irradiate the display panel with light; a directional light unit disposed on an upper portion of the display panel, refracting the light supplied from the light source at a first angle to travel from the non-display area to the display area in total internal reflection, reflecting some of the totally internally reflected light at a second angle, and then supplying a light reflected by an object having biometric information to the display panel; and an optical sensor disposed below the display panel and receiving the light exited from the directional light unit.
