APPARATUS FOR DISPLAYING A HOLOGRAM

摘要

An embodiment of the present invention relates to an apparatus to display a hologram with an interference pattern. The apparatus to display a hologram with an interference pattern includes: a display panel to form the hologram in a space therein; a camera to detect a location of a user; a light path conversion panel to refract light corresponding to the detected location of the user by forming a prism pattern; and a driver to apply a drive voltage to determine a tilt value of the prism pattern to the light path conversion panel. The light path conversion panel includes display electrodes formed in a first direction and is divided into a plurality of groups; a connection electrode formed in a second direction crossing the first direction and includes an end forming a pad portion; and a common electrode form between the display electrodes and a liquid crystal cell to face each other. The connection electrode commonly connects display electrodes having the same order belonging to the groups on an end thereof.
