Abstract

Current cathode ray tube (CRT) terminals scroll data one line at a time. That is, Line 1 is replaced by Line 2, Line 2 is replaced by Line 3, etc., and the last line is replaced by the new line added to the screen. The problem with this method is the data cannot be read as the display is scrolling. If the characters were to move up the screen smoothly like credits on a movie screen, the information could be read.
