Graphic Video Displays for Process and Man-Vehicle Control
Over the last few years great progress has been made in the field of visual displays. Today such displays are not only passive devices like typewriters or plotters but more active devices for an interactive dialogue between men and computers. With the cathode ray tube (CRT) as the most common output device for todays visual displays we can generally find two kinds of displays. There are the so called vector-displays (or X-Y-displays) with a mostly analogue random deflection of the electron beam and with stroke writing generators; there are the so called raster-scan-displays with a deflection usually in a standard television raster, with point raster generators and using normal television monitors for the image output.
