In a vector stroke type of display, the cathode ray tube (CRT) deflection coils require different periods for their deflection currents to build up between the display of consecutive characters, depending upon the separation distance between those characters on the display face. In the past, a maximum deflection current build-up time was assumed for each intercharacter display period. Since all of the vector strokes must be generated before the CRT phosphors decay, it becomes increasingly difficult to display large quantities of information.
