Abstract

This technique is for obtaining alphanumeric display from digital coded data. The character font is contained on a rotating belt. The characters can be physically cut into the belt or photographically generated on it. In addition to the character information, the belt contains a data. The character font is contained on a rotating belt. The characters can be physically cut into the belt or photographically generated on it. In addition to the character information, the belt contains a timing mark which is used for operating an external clock for controlling display of the characters. Four display positions are shown. The belt is driven by a drive pulley and an idler pulley so as to pass over the four display positions which contain light sources.

The character font is contained on a rotating belt. The characters can be physically cut into the belt or photographically generated on it. In addition to the character information, the belt contains a timing mark which is used for operating an external clock for controlling display of the characters. Four display positions are shown. The belt is driven by a drive pulley and an idler pulley so as to pass over the four display positions which contain light sources. When the desired or addressed character is over the appropriate display area, the light source associated with that area is strobed thus displaying the character on an adjacent phosphorescent or ground glass screen. The use of phosphorescent or luminescent material for the viewing surface integrates the light output thus reducing flicker.
