Abstract
A digital hologram image reproducing device includes a light modulator reproducing a hologram interference fringe image, a first panel driving circuit which scans a first display panel and writes data of the hologram interference fringe image to the first display panel, a first timing controller controlling an operation timing of the first panel driving circuit, a second panel driving circuit which scans a second display panel and writes data of the hologram interference fringe image to the second display panel, a second timing controller controlling an operation timing of the second panel driving circuit, and a panel synchronization circuit which simultaneously transfers a polarity control signal received from one of the first and second timing controllers to the first and second panel driving circuits.
