RASTER SCAN DIGITAL DISPLAY SYSTEM ABSTRACT An all points addressable raster scan graphics display system is operable in two modes. In the first mode, data is extracted from a refresh store, serialized, modified, and applied to a display device at a first frequency. In the second mode, data is extracted from the refresh store, serialized and partially modified at said first frequency, but it is then further modified and passed to the display device at an even sub harmonic, for example half, of the first frequency. The further modification includes concatenation of successive groups of display data bits. Accordingly, with the raster scan device operating at a constant scan velocity, the first mode provides a high picture element definition but relatively low color definition display, and the second mode provides a display with an even submultiple, for example half, the picture element definition but considerably greater color definition.
