Method and system for displaying an image on a screen

#The present relates to display boards in general and to remotely changing the displayed information on the display boards in particular.

#One common form of display utilizes poster displays usually located at strategic road junctions for maximum effect. Such posters are commonly pasted on large display boards and remain for the time period paid for, after which the poster is replaced. A major disadvantage of the poster display is that it is restricted to displaying one poster at a time.

#In order to maximize the available net display area, various systems have been developed which allow several, usually not more than three, separate advertisements to be displayed on the same display area. One system uses a rotating screen which contains two advertisements, one of which is visibly displayed at a time.

#The present invention will be understood and appreciated more fully from the following detailed description taken in conjunction with the appended drawings in which:

#FIG. 1 is a schematic illustration of a display system, according to a preferred embodiment of the present invention.

#FIG. 2 is a high level block diagram illustration of the components of the display system of FIG. 1;

#Reference is now made to FIGS. 1-3A. FIG. 1 is a schematic illustration of a display system, generally designated 10, according to a preferred embodiment of the present invention. FIGS. 2 and 2A are high level block diagram illustrations of the components of the display system 10. FIGS. 3 and 3A are side view of the display screen 12, used in the system.

#The display system 10 comprises a display screen, generally designated 12 connected, via an interface and control unit 14, to a computer system 16 Computer system 16, which is preferably situated at a separate central location, remotely communicates with interface and control unit 14 to direct the operation and control the display of an image 15 on the display screen 12. The display system 10 further comprises drive means 18, operable by computer system 16 via interface and control unit 14, printing means, generally designated 20, for depositing color images on to the display screen 12, and erasing means, generally designated 22, for erasing or removing the deposited toner. Printing means 20 and erasing means 22 are connected to interface and control unit 14.

#Display screen 12 comprises a plurality of display screens 26, 28 and 30, which are superimposed on each other, each of which is utilized to display a different color. The plurality of display screens 26, 28 and 30 are situated one behind the other so that the display screen 12 displays a composite image comprising the three images deposited on each of the display screens 26, 28 and 30.
