ABSTRACT:
A flat display system having a display screen consisting of a planar arrangment of a plurality of segments has an isosceles triangular form with an apex angle of 90 degrees, the segments being selectively operated for optical display. The optical display is achieved by electrically, thermally or magnetically changing the optical character of selected segments. The segments can recoverably or reversibly undergo a change of the optical character, and they permit either still display or motion display.
