In a display system including a screen memory having a one-to-one correspondence to the characters to be displayed on a cathode ray tube or CRT, a character generator for generating a bit stream indicative of a character selected by an output of the screen memory and a CRT control circuit for generating the display addresses corresponding to the display positions on the CRT and the raster addresses for selecting the relation between the character block of the character generator and the scanning...

A display arrangement consists of one or more elongate display devices, each of which has a number of separately energizable display areas positioned along its length. When energized, each display area is seen as a bright patch of light. As it is very difficult to arrange that the display areas extend right to the extreme ends of the device, optical deflection means are positioned in front of the display areas to magnify the size of each so that the total display area extends over the whole leng...
