Abstract
An image information displaying system comprises a transparent support, a hologram screen attached to the transparent support, a radiation unit for radiating image information on the hologram screen, a sensor for detecting the ambient condition within the viewing angle of the hologram screen, and a controller for controlling the radiation unit based on the signal from the sensor. The image information displaying system, which is inexpensive, long in service life, superior in eye-catching effect and low in running cost, consumes less energy and is controlled by a central control unit connected thereto through a communication line. The lower end of the hologram screen is 80 to 180 cm from the floor level.
