A review of the principles and applications of display systems is given. A state-of-the-art survey is made of the various types of display devices and their disadvantages. A study is made of the problems associated with two particular display devices and solutions found by the use of hardware and software techniques. A communications line is occupied for an excessive amount of time when drawing graphs on a standard incremental plotter from a remote computer. This time was significantly reduced for low cost by using a satellite computer and trying various alternative coding techniques. A low cost interactive raster scan graphics system was developed that used a magnetic disc to refresh television monitors. This system was used to determine the best method for overcoming the crossing vector erasure problem. A system using the improvements to both the display devices is proposed as a further development.
